Petrov is an old purchaser of Hydrosila Group in Russia. He cooperates with AAK on some non-standard hydraulic pilot operated relief valves and often discusses some difficulties and complications of hydraulic pilot operated relief valves. In the second half of last year, they needed to purchase a hydraulic pilot operated relief valve to test an agricultural machinery equipment. Due to urgent time, Petrov purchased from a Russian hydraulic relief valve manufacturer, who delivered 30 hydraulic pilot operated relief valves in 30 days. During the test run, the hydraulic pilot operated relief valves screamed at about 1.5MPa before opening, as well as at the start and stop. Petrov contacted the manufacturer of the hydraulic relief valves, and the manufacturer replied that the non-standard customization was completely based on the drawings provided, and the dimensional accuracy also met the requirements. Their engineers independently tested the hydraulic relief valves and found that there was really no abnormality. The boss was dissatisfied with the one week of delay due to the test run and asked Petrov to repurchase the hydraulic pilot operated relief valves. Because the hydraulic relief valve problems encountered before were solved by AAK, Petrov emailed me again. AAK engineer preliminarily judged that there may be problems in the design of the hydraulic pilot operated relief valve according to his fault description, the drawings of the pilot operated relief valve, the working parameters of the hydraulic system of agricultural machinery, and the video of the test machine. Knowing that he still has one month of flexibility, AAK can modify the original design of the hydraulic pilot operated relief valve and send 12 samples within 30 days. Four weeks later, AAK sent 20 samples of hydraulic pilot operated relief valves, which were installed and debugged without screaming, and the hydraulic power unit was started or closed for many times still without screaming. Petrov was surprised that AAK engineer found and solved the problem of hydraulic relief valveS at one time, while the original Russian hydraulic relief valve manufacturer can do nothing? Because the scream of pilot operated relief valve is often generated by high-pressure oil through damping hole or valve port, AAK engineer added inclined hole of valve seat and vibration elimination cavity in the original design. In this way, the dynamic and static characteristics of the hydraulic pilot operated relief valve can be improved, the screaming can be eliminated, the noise can be reduced, and the pressure control accuracy can be improved at the same time. AAK strong engineering team not only has the concept of German HAWE, but also has the experience of Italian Oil Controlï¼?the problem can be found at one time. After the successful test run, Petrov privately told us that the boss was very satisfied that he found a
Zero from Italy often purchases hydraulic valve blocks. In previous years, his customer gave 95 days for delivery date. Some time ago, the customer had an urgent order for 1,200pcs of hydraulic valve blocks, and there was only 60 days from the sample of hydraulic valve blocks to delivery. For non-standard hydraulic valve blocks, the lead time is less than 30 days from drawing design, sample, service life test, production and delivery. Zero consulted all hydraulic valve block manufacturers in cooperation. They all said that it would take 60 days to complete the urgent order of 1,200 hydraulic valve blocks only for production, and the lead time in 90 days is necessary. Zero can't refuse the customer directly, so he has to find a new manufacturer of hydraulic valve blocks. Zero also understands that it is not easy to find a reliable manufacturer of hydraulic valve blocks. Moreover, this is an urgent order, and the processing of hydraulic valve blocks is also complex. There was no reply from all the manufacturers he contacted on the Internet. Occasionally, he mentioned this urgent order of hydraulic valve blocks with his friend Caled. Caled introduced him to try AAK hydraulic valves. Caled is a customer that I have worked with for several years on integrated valve blocks. Caled told Zero that AAK helped him solve several urgent orders for manifolds, and the quality was guaranteed. Zero said frankly that he was introduced by Caled and hoped to get our help. According to the drawing sent by zero, the hydraulic valve block has long and thin channels and complex oil circuit design, which is unbearable for general processing. AAK technical team first arranged the production procedure and calculated the daily output of hydraulic valve blocks. It would take 30 days to complete this urgent order. While Zero was pleased, he seemed a little worried about the quality of AAK hydraulic valve blocks. Three weeks later, their engineers tested AAK hydraulic valve block samples. The overall accuracy parameter of the hydraulic valve block is 5% higher than that of the original manufacturer, which proves what Caled has mentioned that AAK quality mentioned is guaranteed. After working overtime for 30 days, AAK successfully completed the urgent order of 1,200 hydraulic valve blocks for Zero, which is half less than the 60 days of lead time required by peers. Zero was surprised how AAK achieved it? AAK adopts the machining center of compound tools to combine two or more similar or different types of hole machining tools into one special tool. In the process of machining, reduce the tools required for machining X, Y, V and U partial views, and complete the process combination of multiple processes such as drilling, reaming, spot facing and boring. At the same time, one tool can simultaneously process threaded bottom holes, 45 , 15 , R0.1 chamfer and outer counter bore, which greatly
Kayden, from AH Garner company in the UK, has successfully purchased hydraulic valve blocks in Ningbo in recent years, and has cooperated with AAK on some high requirements hydraulic valve blocks for many years. He sent an email at the end of last year: I need AAKâ??s help. After communication, we learned that a new hydraulic equipment of their company was complained by customers about oil leakage in about 3 months. After inspection, their after-sales personnel found that when the equipment is switched with high-speed and high-frequency action under high pressure, the small O-ring of the cover plate of the hydraulic valve block is prone to oil leakage. The engineer asked Kayden to find the original supplier to replace the hydraulic valve blocks or cartridge valves. Unfortunately, Kayden purchased the hydraulic valve blocks and threaded cartridge valves from two factories. The manufacturer of the hydraulic valve blocks replied that the thread size accuracy of the cartridge valves did not meet the standard and caused oil leakage, while the cartridge valve manufacturer said that the accuracy of the hydraulic valve blocks did not meet the standard. The hydraulic valve blocks and cartridge valves have passed the inspection. How can there be a problem as soon as they are assembled on the equipment? Kayden suspected that the design of the hydraulic valve block was flawed, but the engineer thought the design drawing was in line with the principle. The customer didn't receive the solution, and complained to the boss, who asked Kayden to completely solve the oil leakage problem of the hydraulic valve blocks within 30 days. Now Kayden was stumped and didn't have a clue. I asked Kayden to send us the drawings of the hydraulic valve block and cartridge valve, and system principles. AAK engineers found no problems after analysis. Our engineer asked Kayden to provide the video after the equipment was started up. Combined with the system schematic diagram and equipment fault video, our engineer judged that the position of installing O-ring at the interface of hydraulic valve block and cartridge valve was inappropriate. If the position of the O-ring is lowered, and the cover plate O-ring is completely free of oil, install and fasten the cartridge valve cover plate, and produce the hydraulic valve block and cartridge valve in a same factory, the oil leakage problem of the hydraulic valve block may be solved completely. Kayden seems to have seen the dawn and asked AAK to make samples. After 25 days, AAK sent out the integrated hydraulic valve block sample. A few days ago, Kayden emailed us that it has been 3 months since the hydraulic valve block was replaced with AAK samples, the equipment works normally without oil leakage. Kayden told me that AH Garner engineer admired AAKâ??s strictness in details. It is so obvious, why didn't he find such an obvious problem?
Chinese hydraulic valve manufacturers, the number of exports in the past 2 years is slowly increasing, which also seems to indicate that the quality of Chinese hydraulic valves has been recognized. Ten years ago, almost all Chinese hydraulic valves were supplied to domestic equipment manufacturers, and AAK began to provide samples for HydraForce. AAK hydraulic valves have indeed made a lot of progress in manufacturing / R & D in recent years, especially the export of high-pressure hydraulic valves. According to the data of Ningbo customs, AAK hydraulic valves account for more than 68%. The rapid growth of AAK hydraulic valves is due to the strict ODM, operation specification and quality control process for these big brands, which is more strict than the ISO certification system. When we communicate with any hydraulic valve customer, we don't care much about the specific PO amount of a hydraulic valve, but focus on the cooperation opportunities with him, the supply relationship of common destiny, especially the market prospect. AAK hydraulic valves have surpassed many peers in the market and research and development in recent years, but in the part of the market, especially in the mature developed market, there is a weakness in the market experience. Using AAK hydraulic valves manufacturing and R & D capabilities, combining with customers' industry experience and business creativity to jointly build a hydraulic valve supply chain system is our direction. It must be admitted that the way of thinking of European and American people in many commercial parts is worthy of our reference and learning. Therefore, AAK hydraulic valves expect to establish a business relationship of the community of common destiny with real hydraulic valve customers. Today, the new generation of hydraulic valve practitioners in Europe and the United States has been separated from manufacturing for decades. Their difficulty is how to find a healthy, sustainable, guaranteed and common fate hydraulic valve supply chain and effectively realize the actual commercial delivery. Perhaps, China's small and medium-sized hydraulic valve enterprises and European and American small and medium-sized hydraulic valve enterprises will find a better combination of interests, and then jointly create new users, which may be a new trend of globalization in the future. COVID-19 is impeding the development of globalization, but the globalization of hydraulic valves can not stop itself. The globalization of Chinese hydraulic valve manufacturers will not only stay at the level of hydraulic valve manufacturing and export. AAK is more concerned about how to make effective use of the favorable position of AAK hydraulic valve manufacturing and R & D, and then combine the business experience of the local market of developed countries to resort out and shape the innovative hydraulic valve business model, such as the software service module or platform of a hydraulic valve supply chain system.
According to the financial dept this morning, there was a sample fee for hydraulic pilot-operated relief valves. I knew it was from ROQUET company in Spain. One year ago, Domingo in their company had a hydraulic pilot-operated relief valve that needed AAK to make samples, but was unwilling to pay $2,000 of the sampling fee. The original factory didn't need them to pay, so they chose that factory to produce this hydraulic pilot-operated relief valve. Last week, Domingo came to me again to ask if there was time for sampling and they would pay the sampling fee. After communication, it was learned that the hydraulic pilot-operated relief valves shipped by the original factory were used in the hydraulic power unit. Less than half a year, it was reported for repair by the customer. It is easy to have insufficient power supply of the hydraulic system during the construction process. The after-sales engineer found that the wear of the valve spool of the hydraulic pilot-operated relief valves led to leakage. He had to use the alternative pilot-operated relief valves first and asked Domingo to contact the original manufacturer to solve the problem. The original manufacturer reported that the hydraulic pilot-operated relief valves had not been worn for more than 1 year previously. The working pressure is more than 450bar this time. The domestic hydraulic pilot-operated relief valves can only have a service life of half a year. If you want to find a hydraulic pilot-operated relief valve with a service life of more than 1 year, you can only buy it from HAWE in Germany. They are the best manufacturer of hydraulic pilot-operated relief valves with high pressure resistance in the world, but the price is estimated to be more than twice that of Chinese manufacturers. Domingo was a little helpless and asked the boss whether to purchase directly from HAWE in Germany or continue to look for hydraulic pilot-operated relief valve manufacturers in China. Because the alternative hydraulic pilot-operated relief valves were used on the construction site, they still had a 6-month buffer period. The boss asked him to look for the hydraulic pilot-operated relief valves under high pressure at the same time. At this moment, he thought of AAK. When I told him that the key point of the service life of this hydraulic pilot-operated relief valve is to resist high pressure, AAK has an engineer who has worked in HAWE Shanghai factory for 8 years, our production of high-pressure hydraulic valves is just to benchmark with that of German HAWE company, he seems to realize that perhaps AAK can sample a hydraulic pilot-operated relief valve with a service life of more than 1 year this time. AAK replied that it could complete the samples of 12 hydraulic pilot-operated relief valves within 1 month, and the warranty was more than 1 year. Domingo remitted the sample fee of US$2,000 the next day.
Yesterday, a hydraulic valve customer who has cooperated for 5 years sent me a message: I am surprised that you AAK hydraulic valves update information on the official website (www.aakindustry.com) every day. I spent 45 minutes on your official website today. I have never stayed on the official website of any factory for more than 10 minutes. I think this should be greatest encouragement to us. Some people may not understand why they write these hydraulic valve information. I think this is the charm of words. Words are the most basic logic of thoughts. All human thoughts will be stored in the form of words. For example, no matter how classic speeches and movies are, we will finally record them in the form of words to analyze their core ideas. Words are the best way to show human thoughts and the best way for human beings to capture effective information. Many years later, it would be our honor if AAK could record, store and disseminate the difficult and miscellaneous diseases, technical essentials or innovations about hydraulic valves. I have analyzed some manufacturing bosses who are invisible champions. They are basically good at writing. Almost all those who can write well and stick to writing are the top 1% of the industry. The new customer is a stranger. How does he come to us step by step? I think maybe so: 1) Customers are attracted by your spiritual world, not your professional ability and case. 2) The content you write has enough professional height, and the actual case is both specific and vivid. 3) The most important and only thing is that he trusts you. This is all. I have always believed that those engaged in manufacturing do not have shortcut keys. If they do not understand the essence of manufacturing, they will not be able to win orders. If you stare at the hydraulic valve order every day and study how to grab the hydraulic valve order every day, don't you think it's very low? AAK hydraulic valves concept solves your doubts and difficulties, and never deliberately sells hydraulic valves.
William comes from a Canadian hydraulic equipment company and has purchased hydraulic valve blocks in Ningbo for several years. AAK also supplies several difficult hydraulic valve blocks to their company. Although the quantity is not big, AAK service makes William very satisfied. In the second half of last year, William emailed an inquiry for a big quantity of order for hydraulic valve blocks. William said that the quotation was 40% higher than that of other hydraulic valve block manufacturers. I'm not surprised at all that he advised that the price of AAK hydraulic valve block is 40% higher. According to the hydraulic valve block drawing provided by William, AAK engineers found that according to the working condition requirements of the hydraulic valve block and the minimum wall thickness between two adjacent parallel holes (including installation threaded holes) in the middle of the valve block designed on the hydraulic valve block drawing is less than 4mm, the 6061-T6 Aluminum material marked in the drawing is not suitable, because this wall thickness can not bear the pressure of 350bar at all. During the operation of the equipment, the hydraulic valve block is likely to be broken down because it cannot withstand high pressure, that is, the materials used for the hydraulic valve block must be changed, rather than blindly follow the original hydraulic valve block drawing. AAK uses 7075-T6 aviation aluminum, which is the root cause of 40% higher price. A week later, William replied that he also sent the inquiry to the old hydraulic valve block supplier and more than 10 other hydraulic valve block manufacturers, but none of them suggested change the aluminum materials. He wondered whether AAK deliberately changed the materials for more profits. This large order of hydraulic valve blocks had been placed with the original supplier. Then I replied with a few words: good luck. Two months later, William sent an email saying that he regretted that he had not followed AAK suggestion at the beginning. The hydraulic valve block sample from old supplier was debugged 3 days after the equipment was installed. The manufacturer of the hydraulic valve blocks said that the sample was completely in accordance with the drawing and the development cost could not be refunded. The equipment commissioning time was wasted. The boss was very unhappy and asked William to try AAK samples even if the price was 40% higher, and asked to send the hydraulic valve block samples as soon as possible. AAK uses 7075-T6 aviation aluminum to make samples by soonest. After 30 days, AAK sent 2 samples of hydraulic valve blocks. Last Monday, when I opened the mailbox, I saw the unread email of hydraulic valve blocks from William. I knew that AAK hydraulic valve blocks passed the test of equipment commissioning. After opening, as expected, he placed a large order of 800 hydraulic valve blocks at one time. He also felt sorry to mistake AAK professional suggestion for deception.
Today's weather is fine and I'm in a good mood, too. It took us 6 months to finally send the samples of the hydraulic counterbalance valves used in the sandstorm to Leonard. Their company has operated hydraulic equipment in Italy for more than 30 years. Leonard has been successful in purchasing hydraulic valves. AAK is their old supplier of hydraulic valves, but he has not purchased hydraulic balance valves from AAK yet. In the past, I asked why there was no inquiry or sampling of hydraulic counterbalance valves. He advised that their hydraulic counterbalance valves were purchased from another supplier who had cooperated for many years. At the beginning of last year, Leonard sent an inquiry for the hydraulic counterbalance valves. At that time, I was a little surprised. I estimated that he had trouble purchasing hydraulic counterbalance valves from the original manufacturer. After communication, it was learned that their company had a batch of hydraulic equipment sold to the Middle East in previous years, and the hydraulic counterbalance valves used had to be replaced almost every 6 months. The customer was not very satisfied with this high-frequency after-sales service. The original manufacturer said that the hydraulic counterbalance valves used in other places do not need to be replaced for 1 or 2 years. There is often haze or sandstorm weather in the desert areas of the Middle East, and the solid particles will virtually cause corrosion to the exposed surface of the hydraulic counterbalance valves, resulting in a high replacement frequency of the hydraulic counterbalance valves, and there is no good way to solve it at present. Leonard contacted AAK to improve their after-sales service. Try AAK hydraulic counterbalance valves to see if they can be used for more than 6 months in a sandstorm environment. According to the hydraulic counterbalance valve drawings from Leonard, the parameter requirements are of medium grade. The core is to select the stainless steel with the best corrosion resistance as the external parts of the hydraulic counterbalance valves. I suggest Leonard ask his customer to send the particles in the worst weather to AAK, analyze the PH of the environment, and then increase the PH by 30% to test the service life of different steels. Three months later, Leonard asked about the progress of the hydraulic counterbalance valve samples and joked that if AAK development is successful this time, all their future hydraulic counterbalance valves will be purchased from AAK. Another three months later, a special steel produced by ArcelorMittal group from Luxembourg was successfully tested by AAK technical team. Using this special steel as the external part of the hydraulic counterbalance valves can ensure corrosion resistance for at least 1 year. It took us 6 months to finally send samples of the hydraulic counterbalance valves used in sandstorm to Leonard.
Yesterday, a person of the same export trade of hydraulic valves came to my office. He lamented that it was too difficult to do the export of hydraulic valves. I thought he met someone who blackmailed him. He said that the export of hydraulic valves . Because the hydraulic valve industry is too professional, he can't contact the decision-makers. From the first hydraulic valve inquiry from buyer to the final shipment, the whole delivery time is long, and it's too difficult to complete an order. This seems to be a common problem of I suggest him read the book the life that has not been destroyed. There is a sentence in the book: the real great is life. After being destroyed so many times, it is the most meaningful to live and die, and to have a bright future. Every time we are confused, it is the hidden willows and bright flowers that life gives us. hydraulic valves, every product is exported to overseas. Whether it is the test order of hydraulic valves delivered by express, the urgent air shipment of hydraulic valves or the big sea shipment of hydraulic valves, it is the result of customers' trust in . The hydraulic valves have strong professionalism, long delivery time, high amount and complex decision-making process, which requires the direct decision-making of senior management and even the boss. It's really difficult to break through layers and open the door of a hydraulic valve order. is not in a hurry to close the deal of hydraulic valves, but regards it as a process of slowly accumulating influence, which is suddenly enlightened. hydraulic valves have invested a lot of money in equipment upgrading, a lot of people in technical iteration and a lot of time in output content. Our ultimate goal is only to influence. Moisten things silently. Day after day, insist on using high stability hydraulic valves, high-quality content and high return rate of reputation to open the door of decision-makers of large companies. hydraulic valves, with tolerance, planted a seed called "influence". Many times, slow down the heart but work diligently and silently, until one day, when you meet a stranger offline, after greeting, he said to you: I already know you. I've read your content. It's really good. At this time, you will succeed. hydraulic valves are just going this way. hydraulic valves only appear in the time and space you urgently need. HYDRAULIC VALVES (202) 2022-04-20
The XX hydraulic manufacturing company in Germany has been rooted in the hydraulic system equipment of the airport for many years. A batch of hydraulic pressure reducing valves purchased by the novice Carla at the beginning of the year were repeatedly complained by the airport, which brought a lot of losses to the company's after-sales service and alerted the boss. In the first half of last year, Carlaâ??s company sold hydraulic power units to Malaysia, which is used to supply emergency fuel to aircraft at the airport. The equipment was reported for repair after running for about a month. The after-sales engineer handled it at Kuala Lumpur Airport and locked the abnormality of the hydraulic pressure reducing valves according to the fault code. Finally, it was found that the sealing ring of the hydraulic pressure reducing valves was corroded, affecting the operation of the equipment. The engineer asked Carla to mail the new sealing ring to the site within 2 weeks. The manufacturer of the original hydraulic pressure reducing valves learned that the sealing ring was seriously corroded and was willing to replace with fluororubber sealing rings, which have the best corrosion resistance, for free. The manufacturer also reminded Carla that when she placed the order, the medium used in the hydraulic pressure reducing valves was not specified, so the conventional nitrile rubber sealing rings were equipped. Considering that Carla is a novice, he is willing to offer replacements for free. Carla thought that the abnormal hydraulic pressure reducing valves were solved in this way. Unexpectedly, the same problem occurred only two months after the replacement. The customer was angry and said that if the second after-sales service still couldn't solved the problem at one time, all the equipment would be returned. Carla went to the original manufacturer of hydraulic pressure reducing valves again, and the manufacturer gave up, because the fluororubber seal ring was their best choice. Now Carla was worried and had to turn to her purchasing director for help. The director asked her to contact AAK hydraulic valves first. If AAK still cannot solve it, there will be no need to waste time on Chinese hydraulic pressure reducing valve manufacturers and can only purchase from Germany. After receiving the email, AAK replied that she should not worry. According to the drawing parameters of her hydraulic pressure reducing valve, it matches a hydraulic pressure reducing valve used in aircraft completely that AAK produced for a Russian customer reorder some time ago. We still have some quantity in stock, and can ensure that AAK hydraulic pressure reducing valves will not be reported for repair for at least one year. The next day, AAK sent 10 hydraulic pressure reducing valves to Kuala Lumpur Airport. Carla emailed us a few days ago that after using AAK hydraulic pressure reducing valves, the equipment has been running smoothly for 6 months,
AAK unique 5 steps sand cleaning method replaces the traditional method commonly used by peers, and completely solves the problem of valve stuck or filter blockage of hydraulic relief valves caused by hidden danger in sand cleaning. The American customer placed an order for the hydraulic relief valves to AAK 3 days after the test run. Most of the bodies of the hydraulic relief valves are made of nodular iron, vermicular iron and gray iron and cast by sand turning with resin sand as the modeling medium. Therefore, there is sticky sand in the casting, which is easy to cause valve jamming and filter blockage. Most of the common sand cleaning methods of hydraulic relief valves in the same industry are shot blasting and electrochemical sand cleaning. These methods have limitations and are not conducive to the stability of hydraulic relief valves. Gabriel is a purchaser of a hydraulic company in the United States. In previous years, he purchased the hydraulic relief valves in the United States. Recently, there is an order for hydraulic relief valves. The production of the original domestic manufacturer is full schedule, while the other hydraulic relief valve manufacturers dislike the small quantity and are unwilling to accept the order. The company asked him to check with Chinese hydraulic relief valve manufacturers. Among several hydraulic relief valve manufacturers recommended by his colleagues, Gabriel chose 3 of them to send samples after a round of comparison. After 20 days, the samples of these 3 hydraulic relief valve manufacturers were generally stable and prone to valve jamming or filter blockage. The root cause was the incomplete sand cleaning process of the hydraulic relief valves. When browsing B2B websites, Gabriel saw that AAK website www.aakindustry.com introduced the 5 steps sand cleaning method of hydraulic relief valves. He left a message on our website: Can AAK make the hydraulic relief valves not stuck or the filter not blocked? We replied him directly: AAK hydraulic relief valves with 5 steps sand cleaning method have been recognized by German customers. You are welcome to try the order. Gabriel subconsciously approved AAK hydraulic relief valves but was still some concerned because of no cooperation before, so he asked for samples to test first. According to the draft of hydraulic relief valves sent by him, we sent samples in 2 weeks. Gabriel issued official PO on the 3rd day after receiving the hydraulic relief valve samples for commissioning, and requested that the bulk goods to be 100% sand cleaned thoroughly. AAK adopts more efficient sand cleaning method and has its own unique 5 steps sand cleaning method for small and complex castings, namely: Artificial aging - Pickling - Rinsing - Rust prevention - Ultrasonic cleaning. Artificial aging is used to reduce the binding force between the casting and sand, acid pickling is used to remove the oxide skin at the joint between the sand and the casting,
Nicholas is from an Italian hydraulic company. Last year, a batch of hydraulic equipment needed to use the hydraulic check valve urgently. Due to tight time, Nicholas purchased in Italy. After installing the local hydraulic check valve, the equipment commissioning was normal, but 3 months later, some users complained that the pressure of the power unit was insufficient. It was found that the hydraulic check valve was stuck on site, resulting in weak pressure supply of the system. Nicholas contacted the original hydraulic check valve supplier and the supplier replied that the jamming was caused by unclean hydraulic oil. The on-site personnel found that the hydraulic oil was polluted, so they could only disassemble and clean the stuck hydraulic check valve. After replacing the hydraulic oil of the whole system, the equipment returned to normal. But a few months later, the same problem happened again, and Nicholas's after-sales personnel operated again as last time. The boss felt that the problem should be solved fundamentally after he knew it. Such after-sales cost is too high. Their engineers fed back that they could only install the filter screen at the inlet of the hydraulic check valve, but the original design of the equipment did not consider the position of the filter screen. It will cost more to refit the whole set of equipment. The boss asked Nicholas to contact more local hydraulic check valve manufacturers to brainstorm. After knowing the problem with this hydraulic check valve from Nicholas, and the hydraulic oil is inevitably polluted, combining with their equipment working conditions and installation drawings, I told him that we can only find hydraulic check valve with filtering function. AAK has similar hydraulic check valve with automatic filtering function. Nicholas doesn't believe that AAK can provide such a hydraulic check valve. After receiving AAK sample and installing it, the equipment works normally. Nicholas asked us how long AAK hydraulic check valve with filter screen can work? We told him that there would be no users to apply for repair within 1 year. Nicholas asked why we are so confident. I told him that a Canadian customer had the same problem last year. We developed this new hydraulic check valve. Within one year, Canadian customer has not reported that there is a problem with this hydraulic check valve yet. Half a year later, Nicholas sent an email saying that his customers had never changed the hydraulic oil after using AAK hydraulic check valves. At that time, in order to save the installation space of filter plug-ins for the hydraulic system of Canadian customer, not to use bulky filter containers, and keep the system clean and extend the service life of hydraulic check valves, AAK designed a hydraulic check valve with filter embedded into the body, that is, the filter screen and the hydraulic check valve are installed in the valve block together.
Whenever there is a new sample of AAK hydraulic valves, I must put it on the desk for a few days. Take a look at the hydraulic check valve with the same attitude of appreciating works of art, and taste a cup of coffee. The work is so simple. The parameters of AAK hydraulic check valves have surpassed most of the domestic hydraulic valve counterparts, and the appearance is also beyond what the 10-year-old hydraulic check valve manufacturers are able to keep pace with. AAK hydraulic valves have no quality complaints for 6 consecutive years. In 2019, AAK hydraulic check valves were used on aircraft by a Russian customer, which is a witness of good quality. AAK hydraulic check valve, how good is it? See the visual comparison in the picture below. Only from the appearance, the hydraulic check valve produced by 10 years old factory has lost. Not to mention meeting the parameters of hydraulic check valve using in aircraft, they may not dare to think or do it. AAK hydraulic valves is an ODM manufacturer for international first-line hydraulic valve brands. It is difficult to find the third one in Ningbo, the hometown of hydraulic valves. You can also have a small try. AAK HYDRAULIC VALVES (198) 2022-04-16
At the weekly meeting of hydraulic valve sales, I always ask our business team to study the production process of hydraulic valves with heart, observe the production of hydraulic valve at the workshop with heart, and think about customer emails with heart. Last month, someone asked me what is with heart? I was speechless for a moment. Recently, I saw an explanation in a book. The difference between using your heart and not is whether you are accepting the world as it is or observing how such a world will affect you? I think the explanation about the difference is in place and hit the nail on the head. Reading the email from hydraulic valve customer, word by word, and even forcibly reciting the whole email, which is still not called reading it carefully with heart. Reading with heart means thinking about these questions repeatedly in the process of reading: 1. What question is the customer asking or requesting about the hydraulic valves? 2. Do we have any problems with these hydraulic valves? If not, how to convince customers that we don't have these problems. 3. Is the answer we are going to provide persuasive? How can customers trust AAK hydraulic valves with the least amount of time? 4. These hydraulic valve problems raised by customers broaden my vision? If it is widened, what is the problem with my original frame about hydraulic valves? 5. Have I understood the customer's needs and emotions? If not, what's my problem? When you read the emails with these questions, you will find that we are not reading the emails, but observing our changes through external stimulation, and even receiving the customer's emotion. This is called reading the emails carefully with heart. AAK team works hard on the hydraulic valves with heart, and understands the needs of each customer with heart. This is our eternal direction!

Lucas is from a Canadian hydraulic equipment company. He found AAK hydraulic valves online last September. His first inquiry was the hydraulic pilot-operated pressure control valve. After 3 rounds of email communication, he placed a trial order for 20 pcs of hydraulic pilot-operated pressure control valves. I received the order so smoothly, but I didn't expect that AAK would almost take the blame for others in the first cooperation. At the beginning of last month, Lucas informed by email that there were problems with all 20 hydraulic pilot-operated pressure control valves provided by AAK. When the equipment was installed and debugged, the hydraulic system went on strike. This is the first time I have encountered such a complaint. AAK will do various tests on each hydraulic pilot-operated pressure control valve before leaving the factory, and deliver it only after it is qualified. I asked the engineer and the workshop to verify. It was proved that the programming and production of the hydraulic pilot-operated pressure control valves are completely consistent with the drawings provided by Lucas, so I can ensure that the samples of AAK hydraulic pilot-operated pressure control valves are qualified. Our engineers speculate that there may be a problem with the oil circuit design of the valve block system, but Lucas engineers believe that AAK is shirking the responsibility. So I suggest Lucas try the hydraulic pilot-operated pressure control valves of other manufacturers to debug. If the hydraulic system is still abnormal, our guess is right. Two weeks later, Lucas frankly told us that there should be a problem with the oil circuit design and asked us what good methods we had? The next day, Lucas sent us the video of equipment commissioning. Indeed, during the operation of the equipment, the speed increases when the cylinder of the hydraulic system is lowered, which is equivalent to the increase of flow, and the original set pressure of the hydraulic pilot-operated pressure control valve will also increase, resulting in the instability of system pressure. Therefore, it is inferred that the instability of pressure is caused by the thin oil passage of the hydraulic valve block in the system. We suggest that he send us the schematic diagram of the hydraulic system. After analysis, AAK engineers believe that the oil circuit design cannot match the working conditions of the equipment. AAK plans to design and process a new hydraulic valve block, and then installs the AAK hydraulic pilot-operated pressure control valves to debug the equipment. If it is not successful, AAK will not charge any fee for the hydraulic valve block. A month later, AAK sent out the newly designed hydraulic valve block. Lucas sent an email 3 days after receiving AAK hydraulic valve block. He informed that after installing the AAK designed hydraulic valve block and the hydraulic pilot-operated pressure control valves, the hydra
Last Friday, I received an email from Shikha, an Indian hydraulic directional valve customer. I was depressed all weekend and didn't even want to reply to the email. In July last year, Shikha placed a trial order for a hydraulic directional valve. Three months later, Shikha asked the price of the hydraulic directional valve to be reduced by 40%, on the grounds that the order quantity of the hydraulic directional valve is bigger now. At that time, we only reduced the price by 5%, but Shikha forwarded the email of other manufacturer accepting the price reduction to me. It means that if AAK hydraulic valve can not accept the price reduction, the order will be placed with other hydraulic directional valve manufacturer. It turned out that he tried the order at AAK and another manufacturer at the same time last July. Last week, Shikha contacted AAK again and asked us to accept the same price as last time. I felt that the hydraulic directional valves he purchased from other manufacturer was not smooth, then he turned back to AAK, so we insisted on the original quotation and got his weird email on Friday: "Why does AAK have to make money to make this hydraulic directional valve? Don't many manufacturers in China make a few points of profit?" Indeed, there are hydraulic directional valve manufacturers doing market common products. The only thing they can do is to compete with low price, and then make small moves under table in production. This is the involution of the hydraulic valve industry. AAK does not want to accept such orders for hydraulic directional valves, nor does it want to contact such customers. No matter what enterprise, if it doesn't make money, it can't find its mission, vision and values. If an enterprise deliberately creates its mission, vision and values, it is illogical. If the enterprise doesn't make some money first, where will these things come out of the mind? No matter how small an enterprise is, it may not realize the value of the enterprise until it has a net profit of at least one million yuan. For example, in what aspects has AAK hydraulic valves created value for customers and brought additional benefits to customers, as well as benefits that can not be given by hydraulic valve peers, not to mention the R & D cost of hydraulic valves, production process upgrading cost and equipment renewal cost. On the way of making money continuously, the enterprise's mission, vision and values will be clearer until the enterprise's mission, vision and values are slowly found and what the enterprise really wants to say and do. In the past few years, the conversion rate of AAK online inquiry is 17%. Does this 17% seem not high enough? But AAK never does business for poor enterprises. Our customers are concentrated in European and American brand hydraulics, and their operation is standardized. As long as the quality of your hydraulic valves is stable, it is really easy to discuss the hydraulic valve project, rather than forcing th
Since the epidemic, many work forms have changed. Whether working at home or in 3 + 2 mode, it tells us that the future organization will be a new mode, and the manufacturers of hydraulic valves are no exception. My understanding of the future factory is that the factory is a factory, only a limited production department. Just like our hydraulic valve factory in Cixi, it has only one function - producing hydraulic valves, which is the "1" in the "6 + 1" industrial chain. For hydraulic valve industry, "6" in the "6 + 1" industrial chain refers to: 1) hydraulic valve design and innovation, 2) procurement (raw materials, or semi-finished products), 3) warehousing and transportation, 4) order processing, 5) hydraulic valve sales, 6) after-sales and service; "1" refers to the production of hydraulic valves. A few years later, our hydraulic valve factory is no longer crowded. The hydraulic valve workshop is either the sound of machine tool cutting metal, or 2-3 masters who give machine tool instructions or maintenance. Small bosses shouldn't care about the macro-economy, which has nothing to do with you and me. Just like me, you can focus on a subdivided field of hydraulic valves, and it is enough to achieve the top 1% in this field. Please note, it is not Top 1. AAK has always focused on the single product of hydraulic valves. It works online for 4 hours a day, which is 7,300 hours in 5 years. It has reached the top 1% of the subdivided field of hydraulic valves. If your enterprise can't reach the top 1%, add another 2 years and reach 10,000 hours in 7 years. You must be the top 1%. Seven years is a watershed for many enterprises. Seven years later, if your enterprise is still "poor", there must be problems in your cognition, thinking and method. The "conspiracy theory" on the Internet makes those with simple brains look less simple. Online "knowledge fast food" makes those who never "think deeply" look like they can "think deeply". This is not a good way to do the hydraulic valves. Online, our circle is no longer restricted by the actual conditions and regions, and it is easier for those with similar interests to gather together. Although you may be in completely different industries, or even you and I are far from each other, the same combination of "cognition" and "Three Reviews" makes you attract each other. AAK hydraulic valves adhere to our three views and the top 1% of the industry. AAK hydraulic valves adhere to a group of people, a lifetime and one thing, let each user use AAK hydraulic valves without any trouble. AAK hydraulic valves adhere to the principle of integrity, does a good job in the business of AAK hydraulic valves, and sincerely treats the customers who purchase each hydraulic valve. Let more customers use good hydraulic valves with real materials without wasting money. AAK hydraulic valves, top 1%, welcome to give it a try. AAK HYDRAULIC VALVES (194) 2022-04-12
Last October, Henry had planned to go to Hawaii with his family for a vacation. The day before he left, he was informed that a customer complained about the vibration problem of his company's hydraulic power unit during low-speed operation. The boss asked Henry to solve the problem immediately. As the purchasing manager of the company, he had to cancel the annual leave. The engineer tested the hydraulic system on site and preliminarily judged that the hydraulic counterbalance valve was abnormal. The engineer disassembled the hydraulic counterbalance valve and failed to find out the reason. The hydraulic counterbalance valve was tested separately, and each parameter was up to standard. Henry began to contact the local hydraulic counterbalance valve supplier and wanted to solve it as soon as possible, but there was no reply. Henry found the original hydraulic counterbalance valve manufacturer. The factory said that he OEM the hydraulic counterbalance valve completely according to their hydraulic counterbalance valve drawings. He also specially retested the hydraulic counterbalance valve in stock, and its parameter basis was qualified. Henry was embarrassed to face such a situation. Henry thought of AAK because we helped him solve the difficult problems of hydraulic counterbalance valves several times before. We received Henry's email and understood that neither the original manufacturer nor the local manufacturer provided solutions. According to the working video of the pressure unit provided by Henry, our engineers recognized their preliminary judgment that the hydraulic counterbalance valve was abnormal. The function of the hydraulic counterbalance valve is to balance the "negative load force" opposite to the required movement direction, which makes the hydraulic motor easier to control. The vibration problem in the complaint is that the hydraulic counterbalance valve affects the control ability of the balance circuit to the load. This is just our first guess about the fault. The specific situation needs to be determined in combination with the actual hydraulic counterbalance valve samples. Henry sent us the hydraulic counterbalance valve samples the next day. After our engineers disassembled it, we are 90% confident that our judgment is correct. The check valve throttling groove of their hydraulic counterbalance valve is a traditional design. According to the working condition of their pressure unit, the design of double triangular throttling groove of hydraulic counterbalance valve has a little influence on the stability of valve spool. The hydraulic counterbalance valves we shipped to a Russian customer 2 years ago also encountered similar problems. I suggest Henry redesign the structure of the hydraulic counterbalance valve. A month later, AAK sent out 10 samples of hydraulic counterbalance valves, Henry installed the equipment for commissioning, and there was no vibration problem.
Back from the three-day holiday, the director of the machine tool workshop sent a production report of TRV-08 hydraulic direct acting relief valve for an Indian customer early in the morning. The first paragraph is like this: "the programmers in our workshop made a low-level mistake and compiled the leakage of 2 drop / min in the hydraulic direct acting relief valve into a production process of 5 drop / min. I didn't check it out because I was anxious to go back to my hometown for the holiday". Seeing this production report of TRV-08 hydraulic direct acting relief valve, I was angry, not because the hydraulic relief valves produced has to be wasted, but because the workshop director indicated it as a low-level mistake in order to whitewash it. In every production link of hydraulic valves, error is error. There has never been any low-level error or high-level error. As long as you make a mistake, it's either bleeding or dying. I replied to him: 1. Re-produce TRV-08 hydraulic direct acting relief valve and work overtime continuously to make up for the the production progress delayed for 3 days. The produced parts of hydraulic relief valves shall be put into the waste warehouse and registered. 2. In the production of hydraulic valves, if you will make a mistake that no one has ever made, you can be promoted from workshop director to production director. The thought of predecessors is the ladder of future generations. To experience the pain of bleeding from mistakes, you can grow. No matter the production programming of hydraulic direct acting relief valves or other production links of hydraulic direct acting relief valves, we should not be careless. AAK hydraulic relief valves, it doesn't matter if there is a mistake. First recognize the mistake, then correct yourself, and then protect customers. You are welcome to try an order with AAK.
For the leakage in the pilot-operated pressure control valves less than 2drops /min, Howard from Accupress in Canada, contacted more than 30 Chinese hydraulic valve manufacturers. Only AAK pilot-operated pressure control valves met the standard and replaced his local factory in the United States. Last year, the hydraulic shearing machine they listed sold well. The boss decided to mass produce it in Suzhou, China. However, the pilot-operated pressure control valve to be used in the hydraulic shearing machine was originally purchased in the United States, and the internal leakage is less than 2drops / min. If the pilot-operated pressure control valve is purchased from China, it will save money and time. While contacting some old suppliers, Howard is also looking for new manufacturers of pilot-operated pressure control valves. We also received Howard's inquiry. The email subject is: can you supply pilot-operated pressure control valves with internal leakage less than 2drops / min for our Suzhou factory? We thought it was a domestic purchase, so we politely refused. Until Howard's second email told us why he wanted to ship to Suzhou, and he contacted more than 30 Chinese hydraulic valve manufacturers, only two of them replied that they could try to make samples of pilot-operated pressure control valves with internal leakage less than 2drops/min, and there was no any reply from the other manufacturers. Howard asked if AAK pilot-operated pressure control valves could meet American factory standards? If not, the sample is meaningless. I told him directly that AAK had tested samples of pilot-operated pressure control valves with internal leakage less than 2drops/min for a German company some time ago. The pilot-operated pressure control valves can be refunded in full if our samples do not meet the standard. One month later, 30 pilot operated pressure control valves were sent to Accupress's Suzhou plant. Four weeks later, Howard sent an email saying that their engineers tested the pilot operated pressure control valves of AAK and two other manufacturers, and only AAK samples met the standard. Some parameters were higher than those of the original American factory, and those of the other two manufacturers did not meet the standards. In particular, AAK pilot operated pressure control valves caught up with and surpassed his American factory, which surprised him. AAK pilot operated pressure control valves can meet such requirements because of two reasons: 1ã??For the pilot operated pressure control valves, the matching clearance accuracy between the valve spool and the valve body directly determines the internal leakage of the whole valve. AAK has German Nagel precision honing machine. After honing, the dimensional accuracy of the cone plating of the valve spool and valve body of the pilot operated pressure control valve is IT7 ~ 4, and the surface roughness can reach Ra0.32 ~ 0.04�¼m, which can not be achieved by most of hydraulic valve
