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
Philip comes from a hydraulic equipment company in Italy. He has purchased hydraulic pressure reducing valves in China for several years. He is also an old customer of AAK. At the beginning of last month, Philip emailed that there was a problem with the hydraulic pressure reducing valves he purchased elsewhere at the beginning of last year, and the company had to pay a lot of money after sales. The boss had big disagree opinion on him. After further communication, we learned that in order to reduce the purchase cost by 17%, he did not choose AAK and purchased hydraulic pressure reducing valves from another factory. The crane sold by Philipâ??s company suddenly increased the load of variable displacement pump during operation, resulting in the control failure of the whole hydraulic system. Under normal circumstances, the hydraulic pressure reducing valve of the variable displacement pump as the emergency safety valve is in the normally closed state. This time, the pressure of the variable displacement pump cannot be released due to the jamming of the hydraulic pressure reducing valves, resulting in the collapse of the system. The customer requests to replace the hydraulic pressure reducing valves on the equipment and compensate the cost of work delay on the construction site. Philip asked the original manufacturer to replace the hydraulic pressure reducing valves. The manufacturer said that the hydraulic pressure reducing valves have been used for more than half a year. The problem of the valve spool sticking is caused by sundries in the hydraulic oil used by the user. At present, this model of hydraulic pressure reducing valves is not in stock, and it will take at least more than a month to re produce. I asked Philip to send me the model and parameters of this style of hydraulic pressure reducing valves. After analysis, AAK engineers found that the hydraulic pressure reducing valves needed by Philip was exactly the same as that ordered by one of our Russian customers last time. We have it in stock. The next day, AAK sent 20 hydraulic pressure reducing valves to Philip by air express. After receiving them, he asked the after-sales engineer to replace it on site. As a result, everything was normal and the crane could operate smoothly. A week later, Philip sent an email saying that thanks to AAK hydraulic pressure reducing valves, which saved the company a compensation. The boss also appreciated AAK for its help and suggested Philip list AAK as their preferred supplier of hydraulic pressure reducing valves. The price of AAK hydraulic pressure reducing valves may be a little higher than that of its counterparts in Ningbo, but you have no worries when using it. AAK knows that the hydraulic pressure reducing valve is the soul of this crane. Therefore, AAK controls the production quality of the hydraulic pressure reducing valves strictly, so that customers can buy it at ease and use it at ease.
