Hydraulic Valve Block Suppliers and Manufacturers

Smith is the head purchasing of a hydraulic company from California. His purchasing of hydraulic valves in recent years has been smooth. In the last hydraulic valve block order, the parameters were normal when the hydraulic valve block approval sample was tested for the first time, but there was oil leakage in the second test on the hydraulic valve block. After rechecking, the oil leaked again in the third test on the hydraulic valve block. Smith communicated with the hydraulic valve block manufacturer for many times but without results. The manufacturer said that this is the traditional sealing process of hydraulic valve block, Smith should either accept it as is or cancel the order. Smith knew that the delivery date confirmed with the customer was due in 1 month, so it was urgent to find a new hydraulic valve block manufacturer to replace the current one. Smith checked the sealing process of no less than 20 hydraulic valve block manufacturers. They all adopted the traditional sealing method of hexagonal plug combined with and sealing gasket. Smith knew that although this sealing method is simple to operate, it has very high requirements for tightening torque. When the torque parameters are not up to standard, the hydraulic valve block is easy to leak. In order to prevent leakage, some hydraulic valve block manufacturers apply anaerobic glue on the threads. During operation, the particles of anaerobic glue fall into the valve hole, causing oil pollution or valve jamming of the hydraulic valve block. The delivery date is approaching day by day, but the new qualified hydraulic valve block manufacturer has not been found yet. Smith is worried and asks around. His friend Caleb gave him the contact information of AAK hydraulic valve. Caleb is also our hydraulic valve customer in the United States. He suggested Smith contact AAK, and told him that AAK hydraulic valve exports to European and American markets all year round and has some unique R & D processes. Perhaps AAK will be different in the sealing treatment process of hydraulic valve block. Smith directly sent us the hydraulic valve block drawing and required that the traditional sealing technology should not be used. A week later, AAK sent the hydraulic valve block sample successfully. Two weeks later, Smith informed AAK by email that the parameters of AAK hydraulic valve block were fully up to standard after 3 tests, and there was still no leakage after the 4th and 5th tests. Smith is very curious about how the sealing process of AAK hydraulic valve block is different from that of other hydraulic valve manufacturers? The vast majority of hydraulic valve manufacturers fail to seal the hydraulic valve block in place because they stick to the rules in technology. 6 years ago, AAK was eliminated by the customer due to the leakage of the traditional sealing technology of the hydraulic valve block. After that, we deci

Malcolm is a purchaser from an American hydraulic equipment manufacturer. He has purchased various hydraulic valves from AAK for some years. We know each other very well. At the beginning of the year before last, their company received an urgent order from a customer in South America. The company required that the accessories of the whole hydraulic system must be in place within 20 days. AAK is their long-term supplier of hydraulic valve blocks. Malcolm estimates that if the hydraulic valve blocks are purchased from AAK this time, including the transportation and customs clearance time, it will be over 20 days. AAK is only required to offer the quotation according to the hydraulic valve block drawings for their file and is informed that due to time constraints, they will first purchase the hydraulic valve blocks from the local hydraulic valve manufacturer this time. About 8 months after our quotation, Malcolm asked by email about what is the reason for the leakage of the hydraulic valve blocks. I asked jokingly if leakage happened in the hydraulic valve blocks purchased locally last time. He said that the customer initially complained that about 30% of the hydraulic valve blocks were leaking. The local manufacturer also replaced the bad hydraulic valve blocks with new ones. However, 3-4 months after installation, the customer reported that there was leakage fault of the hydraulic valve blocks again. Now the customer is not satisfied with the stability of the hydraulic valve blocks and needs the leakage problem of the hydraulic valve blocks solved at one time. The trouble is that the local hydraulic valve manufacturer in the United States does not cooperate to replace the hydraulic valve blocks again. We replied that if we simply look at the leakage cause of the hydraulic valve block, the probability is that the surface roughness of the hydraulic valve block is not up to standard, or the roughness Ra value of the hydraulic valve block is unstable. According to the requirements of these working conditions of your hydraulic equipment, if the Ra value is stable at 0.4um, the problem of hydraulic valve block leakage will not occur. 10 days later, AAK sent 12 samples of hydraulic valve blocks for emergency first. After 20 days, the remaining 30% of the hydraulic valve block was sent from AAK. Now, 12 months have passed, and no complaint from customer. Malcolm mentioned 2 days ago that the customer was ready to place an order again. This time, his owner said that no matter how urgent it was, it was necessary to purchase from AAK, because AAK hydraulic valve block was the most trustworthy, and the owner would communicate with the customer about the delivery date. Why can AAK achieve the surface roughness Ra value of hydraulic valve block to 0.4um? First of all, the Ra value of the hydraulic valve is the cornerstone. The coarser the surface, the easier it is to wear. The intermediate gap gradually increases during use

Recently, I received the second re-order of a hydraulic pressure reducing valve from French client Chinning. I still remember when I first met Chinning in 2020, Chinning purchased hydraulic pressure reducing valves in a hydraulic valve factory and encountered quality complaints from her customers. The hydraulic pressure reducing valve was deformed in less than 3 months, and some valve spools and valve sleeves were seriously worn. More and more customers began to return goods, and the old suppliers did not cooperate with her work. Chinning had a big headache at that time, and the owner kept putting pressure on her to find a hydraulic valve manufacturer with exquisite quality as soon as possible. Chinning did not find a new hydraulic valve manufacturer very smoothly. Because her hydraulic pressure reducing valve had a special use scenario and required high hardness of materials, it was unbearable for ordinary factories. At the same time, under the environmental protection policy of 2019, many previous heat treatment and processing factories were shut down, so the supply supporting system was disrupted, and the heat treatment and processing of many hydraulic valve manufacturers could not keep up. how does AAK ensure the service life of hydraulic valve products We didn't answer directly, but asked her if the hydraulic valves you purchased had the problem of deformation and rapid wear. She also replied quite frankly that she should find a hydraulic valve manufacturer that paid attention to the service life of hydraulic valves in the fastest time. I sent her several samples of hydraulic pressure reducing valve and told her that different parts of our hydraulic pressure reducing valve have different material hardness standards, and some could reach about 50-55HRC or higher. There is even no problem with 65HCR with special requirements. The service life of hydraulic pressure reducing valve is our hard index. More than one week after we sent out the samples of hydraulic pressure reducing valve, we received Chinning's email, including the drawings of hydraulic pressure reducing valve and the hardness requirements for various components. She asked whether we could produce this hydraulic pressure reducing valve? I told her that his hydraulic pressure reducing valve is not difficult, but just the working scene is some special. As long as the heat treatment process is a little unique, it could ensure her requirements. The long service life of hydraulic valve is the most critical.

For the Hydraulic Manifold Block with porous system like cranial nerve, after made samples successfully, They have a special hydraulic manifold block, which includes 13 groups of M32 threaded holes, and all of them are stepped holes. At the same time, there are cross holes, straight holes, and bypass holes. The hole size is required to be more than 8. Compared with the hydraulic manifold blocks with 10 groups of normal threaded straight holes, it is not only complex in structure, but also 20% higher in precision. Arno knew that it was difficult, so he arranged 3 hydraulic manifold block manufacturers for proofing, which lasted 60 days, but all of them failed to meet the standard. This is a test order of hydraulic manifold block from an old customer. Arno wants to struggle again. Due to time constraints, he does not dare to use a new hydraulic manifold block manufacturer. His old hydraulic manifold block supplier is also unreliable. This makes , who has eight years of procurement experience, a little overwhelmed. I had a hunch that this hydraulic manifold block was not simple. Because the PO of hydraulic manifold blocks given to me by is a challenge every time. engineers pondered over the drawing of hydraulic manifold block sent by , and it is really difficult to process, with very high precision. There are not only many pore systems, but also many deep holes, more than 20 groups of 4 deep holes, with a length diameter ratio greater than 25. For M32 threaded holes of stepped holes, the coaxiality between holes is required to be 0.02mm, and the coaxiality between threads and holes is required to be 0.045mm. This complex pore system structure is like the distribution of the nervous system of the human brain. Doctors without more than 10 years of experience in brain surgery may not be confident to operate on the operating table. technical team, after 3 days of internal research and discussion, the plan has been worked out, and our chief engineer will handle the knife, starting from the production drawing of the hydraulic manifold block. However, I replied to that was only 90% sure that the sample of this hydraulic manifold block was successful, and the cost was not low. Maybe hesitated and didn't give any reply for 3 days. On the fifth day, received the development fee paid by him.

hydraulic relief valves . purchased a batch of hydraulic relief valves for crane system in because the original supplier was not able to meet the delivery. He sent an email last week saying with hydraulic relief valves, the stability is 8% higher than that of the original supplier, and there is almost no external leakage. This surprised him. The use experience of hydraulic relief valves has benchmarked with their previous local hydraulic relief valve manufacturers The vast majority of hydraulic valve bodies are made of nodular iron, vermicular iron and gray iron and cast with resin sand as the molding medium. Therefore, there is sticky sand in the casting, which is easy to pollute the oil system and block the valve and filter, which is the key factor affecting the stability of hydraulic relief valves. Most of the common sand cleaning methods of hydraulic relief valves used in the industry are shot blasting and electrochemical sand cleaning, all of which have limitations. 1. Shot blasting can not completely remove the sticking sand from the valve hole with complex structure and small oil passage, which is easy to affect the tightness and product accuracy, and is not conducive to the stability of the hydraulic relief valves. 2. Electrochemical sand cleaning can relatively remove the sticky sand in the narrow oil passage, but it has high energy consumption, high operation intensity of workers, easy to have human errors, can not completely remove the sticky sand, and is not conducive to the stability of the hydraulic relief valves. Improving the quality of hydraulic parts processing process, improving the cleanliness level and ensuring the stability of hydraulic relief valves has always been the hard index of hydraulic relief valves. Auxiliary processing of hydraulic parts mainly includes: sand cleaning of valve body, deburring or residue treatment of parts and cleaning of hydraulic parts. How does do the sand cleaning of hydraulic relief valves technical team has continuously improved the sand cleaning process of hydraulic relief valves after years of technical improvement. For the sand cleaning of small complex castings, has its own unique sand cleaning 5 methods, 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 to peel the sand from the casting, and then the explosion of compressed air during ultrasonic cleaning is used to peel off the sand, so as to achieve the purpose of sand cleaning. has its own unique advantages of sand cleaning 5 methods: (1) it is less affected by the casting structure; (2) it is

new hydraulic relief valve. The drawings of the hydraulic relief valve were sent 1 month after the confidentiality agreement was signed. The customer requested that if we were not able to develop it, they would witness us destroy the drawings and documents of the hydraulic relief valve by video. It's the first time for this customer to be so formal After receiving the drawings of hydraulic relief valve, we knew that it was to match with a set of aerospace equipment developed by a world top 500 enterprise in the engineers reviewed the drawings for 3 days and still didn't write the sample program. This hydraulic relief valve is not only small in size, but also has material requirements, machining accuracy requirements and use frequency requirements that exceed the parameter requirements of the hydraulic relief valves we have seen. We estimated that the overall development When we mentioned and give you 1 year of time. If the development is successful, you can wait for the order of hydraulic relief valve. If the development fails, this will be deducted from the payment for in the future. to say that the customer will prepay for the development cost of the hydraulic relief valve, but if it fails, we will need to refund it by deducting from the future payment gradually. I did not hesitate to reply to the email and was willing to try to develop this hydraulic relief valve. hydraulic relief valve development would be counted as the contribution of the technical team, and the failure would be counted as mine, because I can't fail to live up to the customer's support for our development. Some people in can not understand how this could be a kind of support. Maybe he didn't think about a question, that is, what would the mentality of the technical team be without customer support Behind these are two completely different ways of thinking. One is that if you haven't done it yet, think about failure first, think about whether there is a bottom plan first, and if not, don't do it. There is also a way of thinking, which is to think about how to start first. If conditions permit, start working first. The difference between these two ways of thinking is not just the difference between conservative and radical, but whether people are the key factor to create value. With the starting money, the hard work of the technical team and the best logistics

When I opened the mailbox this morning, I saw an from , which should be a re-order for the hydraulic relief valve, because he asked about the durability of hydraulic relief valve spool last week. Opening the , it is indeed the need for purchasing a large number of 420 hydraulic relief valves, and requiring 3 years of quality guarantee. is a purchaser of . 3 years ago, a customer of his company complained that the crane was easy to depressurize during work, resulting in the inability of the crane to bear the force. Especially after the working temperature reaches 55 C, the pressure cannot go up. Field engineers believe that this is a problem of the hydraulic system, such as low pressure regulation of the hydraulic relief valve, wear of the hydraulic system, or oil pollution. No abnormality was found after inspection. Finally, it was determined that the fault occurred on the hydraulic relief valve. After disassembling the hydraulic relief valve, it was found that the cone valve spool was worn, affecting the sealing of the hydraulic system, so the oil pressure could not rise. The customer does not understand why the valve spool of this hydraulic relief valve is worn after less than 2 years of use. The customer requested to replace with a batch of hydraulic relief valves with durability of more than 3 years and use them on these 12 faulty cranes. At that time, contacted more than 10 hydraulic relief valve manufacturers and got reply that the warranty could not be achieved for 3 years. Some hydraulic valve manufacturers replied that they only have 50% confidence. This result embarrassed Bruce. The customer requirements for the hydraulic relief valve could not be implemented, how he should explain to the owner. I received message from on the of can really provide a 3-year warranty hydraulic relief valve I replied directly: just give it a try then you will know. I can't make money with the trial orders of several samples, and you can't lose money. Maybe was stimulated and sent us the test order the next day for 4 hydraulic relief valves. also frankly told that two other hydraulic valve manufacturers would also try the order at the same time. Their plan is that each factory will be tested for 4 samples, with a total of 12 hydraulic relief valves to meet the urgent needs of customer first. About 2 years after the samples were sent, we received from again for another trial order of 8 hydraulic relief valves. I felt strange and thought that they actually didn't have big quantity order for hydraulic valves. Until last week, from his email, we learnt that they had tested the hydraulic relief valves provided by for 3 years. Indeed, 3 years later, hydraulic relief valves still worked normally, and the hydraulic relief valves provided by the other two manufacturers had faults in less than 2 years.

He has done very well and occasionally inquires about the price with HYDRAULIC VALVE. For the hydraulic check valves purchased some time ago, the production director found that 20% of the hydraulic check valves have parameters that do not meet the standard, so they must get new qualified ones to the workshop within 20 days, otherwise the delivery of customer order would be delayed. Charles asked the original manufacturer of the hydraulic check valve to complete the replacement within 2 weeks. The manufacturer is willing to replenish, but the production can be started only after 15 days, that is to say, it will take 30 days to replenish. tried to find other suppliers of hydraulic check valves, and all replied that it could not be completed in such a short time. realized that something was going to happen and began to look for a new hydraulic valve manufacturer, contacting factories one by one. thought that had also participated in the quotation of this hydraulic check valve, and the samples provided also met the requirements, but it was not considered because the quotation of was slightly higher than that of other hydraulic valve manufacturers by 7%. sent us an e-mail to ask whether the quotation of hydraulic check valve offered 6 months ago can be maintained, and if we can finish an urgent order of 100 hydraulic check valves in 10-12 days. I felt that this should be an order for hydraulic check valve encountered with problem. told us the truth. About 20% of the hydraulic check valves produced by the original factory were unqualified and rejected by their production director. Now he must replenish them as soon as possible. General hydraulic valve manufacturers are unwilling to make such aftercare orders, but HYDRAULIC VALVE don't think so, because , as a production factory, has the same goal as the importer, that is to serve users well, so is more willing to help customers and solve complaints from users together. Fortunately, the corresponding materials are in stock. Combined with the 24-hour production line, our production director conservatively estimates that it can be completed in 12 days. asked us to start blanking now and the hydraulic check valve order will be issued tomorrow. After 10 days, 100 hydraulic check valves were successfully finished. was very happy and quickly air freighted these hydraulic check valves to the Thanks to the God, 100 hydraulic check valves finally arrived at their workshop in 20 days. informed us by email that their engineers installed, debugged and tested hydraulic check valves, which were all normal. The 7% higher price was also agreed by his owner. The owner was very amazed that can deliver so quickly and the quality was better than that of the original manufacturer.

At the beginning of this year, received an order from African customer for excavators with a delivery time of 2 months, which means that all accessories must be in place within 1 month, including 600 hydraulic cartridge valves. The production time for the factory is a little more than 2 weeks. The purchaser Peter sent the order information of the hydraulic cartridge valve to all the hydraulic valve manufacturers he contacted before at the first time. More than 20 hydraulic valve manufacturers said that they could not complete the order of the hydraulic cartridge valve in such a short time, and it would take at least 3 - 4 weeks. His supervisor was not satisfied with this delivery time and asked him to find a new hydraulic valve manufacturer. After the email was sent, there was basically no sound. Peter was very helpless and worried. Peter asked Mark for help. HYDRAULIC VALVE to ask if could produce 600 hydraulic cartridge valves in 2 weeks and CC Peter, and joking at the end of the email that if HYDRAULIC VALVE could not complete the hydraulic cartridge valve order, then there is no need to waste time on looking for a new hydraulic valve manufacturer. According to the drawings they sent, technical department found that this was very close to the hydraulic cartridge valve supplied to a Russian customer last year, so the time in the early stage of the production of the hydraulic cartridge valve was saved. After the price of the hydraulic cartridge valve was approved, the process data could be configured on the computer on the same day and the production could be carried out the next day. 2 weeks later, 600 hydraulic cartridge valves were delivered on time, which was the first of all the accessories purchased by Peter to arrive at the company's warehouse. Peter didn't expect that the hydraulic cartridge valve he was most worried about was the first to be completed. Peter appreciated the advice from Mark and was also surprised that could complete this in 2 weeks, while his previous hydraulic valve suppliers needed 3-4 weeks. Mark told : 1. is his most trusted hydraulic valve manufacturer. can surprise him every time when the hydraulic valve order is urgent. 2. has a large amount of data storage and clear classification. For hydraulic valves with relevant data, they can use the most advanced UG / SOLIDWORK software and finite element analysis method to configure process data in 2 hours, which is 3-6 times faster than that of other suppliers. 3. is equipped with advanced machine tools imported from Swiss, coupled with their own modified fixtures, the production speed is accelerated and man-made errors are avoided at the same time. After listening to the introduction realized that only a good hydraulic valve supplier can make his purchasing smooth. successfully completed this urgent order.

a purchaser of in He is responsible for the procurement of hydraulic components. He has done an excellent job some time ago and has been praised by his supervisor for many times. Before the shopping season, he wanted to relax and planned to go on vacation with his family next week. A phone call from the owner disrupted all his plans. A major dealer in asked for help for a excavator produced by their company within 1 week . His engineer came to the user for routine maintenance and found that there was oil leakage in the hydraulic system. After pressure test, it was found that there was oil leakage in the hydraulic check valve, and 12 excavators had such faults. this hydraulic check valve, and got the reply that it was too cold in at this time. For such high frequency operation, even if the hydraulic check valve was replaced, it was estimated that the hydraulic check valve would still leak oil 1 week later. Unless more low temperature resistant sealing rings are used, this will take time to test, but the finishing time is to be determined. was so helpless, he had to find a new hydraulic valve supplier. asked several local hydraulic valve manufacturers. They either didn't have time to produce or require over 50pcs MOQ. After knowing these situations, the supervisor asked Daniel to give the dealer a plan that can be implemented within 10 days. had to cancel the vacation. thought of HYDRUALIC VALVE who he had contacted for inquiry before. He emailed us to ask whether we can produce the hydraulic check valve for the excavator, which needs to be resistant to low temperature. According to the drawings and working conditions provided by him, we advised that it takes 20 days to customize. All our existing hydraulic check valves are not close to this size. reiterated the hydraulic check valve needs to be low temperature resistant, and frankly told us what they are currently experiencing. I answered directly that the core lies in the low temperature resistant sealing ring. Daniel felt that maybe could solve this problem. After 18 days, we sent a sample of hydraulic check valve. The test results proved feeling. The parameters passed the test and there was no oil leakage at low temperature. The order for 12 hydraulic check valves was also easily confirmed. hanging heart can finally be put down. asked why hydraulic valve manufacturer needs time to be determined to test, and we solved it in 18 days. Why hydraulic valve manufacturer is unwilling to do this small quantities, but it is OK for hydraulic valve. At the same time, the price of hydraulic valve is cheaper than that made in and that made in the .

Yesterday, I received a repeat order for a hydraulic sequence valve from . The first order of this hydraulic sequence valve was placed 3 years ago. Before, I wondered why this hydraulic sequence valve had not been repurchased, thinking that it had been switched back to the United States for production. I really didn't expect to receive the repeat order after 3 years, and the quantity was more than 3 times that before. 3 years ago, company had a newly designed hydraulic pump to be produced in branch, and the pump needed hydraulic sequence valve. If purchasing the hydraulic sequence valve in the , it was expected to take 3 months or more. His owner wanted to try purchasing in , hoping to save half the time. According to the owner instructions, spent 3 days looking for hydraulic valve factories, selected 5 hydraulic valve manufacturers from more than 10 as their hydraulic sequence valve suppliers, and asked them to send reference samples of hydraulic sequence valves to Vietnam for testing. happily reported the purchasing status to his owner, who was satisfied. After received these hydraulic sequence valve samples, he arranged the technical department to match the working conditions for testing, but the results were poor. The matching clearance between the valve body and the valve spool of some hydraulic sequence valves was small. After an additional 20 pressurization, the valve hole was deformed and the valve spool would be stuck. All 5 hydraulic valve manufacturers said that after additional pressurization, they were not able to ensure the quality of hydraulic sequence valve. Time has been wasted for more than 2 weeks. At this time, if returning back to the United States to purchase hydraulic sequence valves, he would be scolded by his owner. to worry. When browsed , he felt that hydraulic valve was some different from the other hydraulic valve manufacturers. He emailed to inquire about the hydraulic sequence valve and frankly told us the problems he had encountered with Chinese hydraulic valve manufacturers. After several rounds of communication and technical team analysis of his drawings, we truthfully told him that existing hydraulic sequence valve samples could not meet his pressurization test. It takes 2 weeks to proofing according to the drawing. If the sample of the hydraulic sequence valve is approved and it takes 25 30 days to produce his order for the hydraulic sequence valve, calculates the time. If the sample of hydraulic sequence valve is successful, the time saving meets the requirements of the owner. If it is not successful, it will waste another 2 weeks. It seems that he has no choice. Somehow, feels that can give him hope and hopes that we can send samples as soon as possible.

Only AAK was able to produce the hydraulic manifold blocks, and its technology is not inferior to American and Japanese counterparts Scott comes from an equipment company in the United States. In the second half of last year, they developed a hydraulic equipment to be introduced at the exhibition. The chief engineer of the company requires the purchasing department to get all hydraulic manifold blocks arrive at the factory within 3 months. There is a hydraulic manifold block. Due to the slow production, the production time of 45 days is not enough. Scott disassembled the hydraulic manifold blocks, purchased the hydraulic valve blocks from one factory and the hydraulic cartridge valves from another factory. All hydraulic manifold blocks and those parts produced separately arrived at the factory in the United States in 3 months. The technicians in the workshop installed them. After a few days of commissioning, they found that there were oil leakage on one hydraulic manifold block, that is the one disassembled and produced in two different factories. The chief engineer requires getting a new hydraulic manifold block within 1 month, otherwise it will be too late to catch the exhibition. Scott contacted the original manufacturer. As a result, the two hydraulic valve manufacturers prevaricated each other. Their engineers also tested the hydraulic cartridge valves and hydraulic valve blocks separately, and there was no abnormality. Scott tried to contact new manufacturers of hydraulic manifold blocks, but they all said that they couldn't get samples ready within 30 days. Scott was worried. Scott saw on AAK website that a hydraulic manifold block was very close to the size he wanted to purchase, so he sent an inquiry. After two rounds of communication, we learned about the problems he encountered in purchasing hydraulic manifold blocks. I told him that if the hydraulic cartridge valves and the hydraulic valve blocks were approved to be no problem, the workshop technician might break the seal ring or shift the seal ring during the installation of the hydraulic manifold blocks. This kind of hydraulic manifold blocks purchased from different manufacturers and then assembled is easy to have problem. A customer of AAK encountered similar problems before. After Scott asked their mechanic to replace the sealing ring, there was no abnormality in the test run, and they could catch up with the exhibition. Scott is glad that the problem of hydraulic manifold block has been solved, and said that for all hydraulic equipment orders after the exhibition, the hydraulic manifold blocks will be purchased from AAK, and also asked us to send hydraulic manifold blocks with similar dimensions to the United States to test stability and service life.

With hydraulic manifolds, the energy consumption of the original unsalable equipment not only decreased by 20%, but also became hot seller is from a agricultural machinery equipment company, mainly responsible for purchasing hydraulic components. In the second half of last year, the sales of one of their rotary tillers were poor. Users reported that the equipment was insensitive and inefficient, and the fuel consumption was 10% higher than that of the same type of equipment. The boss realized that there were hidden dangers in the hydraulic manifolds and asked the engineers to check the causes. However, more than 1 month had passed and there was no practicable plan. The boss was worried and asked to contact the original hydraulic manifold manufacturer to see if they could provide technical support, but they were only good at producing hydraulic manifolds according to the drawings. Connor also asked all his manufacturers of hydraulic components, but none of them gave a plan. When reported these to his boss, he could only helplessly look at his boss shaking his head. the display and introduction of hydraulic manifolds, and left a message: what is the relationship between hydraulic equipment with high energy consumption and slow response and hydraulic manifolds I understood that Connor had a problem with hydraulic manifolds, but it was difficult to answer. After several communications, I learned that his boss was worried, and wanted to solve the problem that had plagued his company for nearly 3 months. According to the hydraulic manifold drawings and the video of rotary tiller work sent by engineers had discussion. The probability was that the hydraulic manifold design had hidden problems. From the analysis of hydraulic manifold and system schematic diagram, there were certain energy conflicts between the design of some oil circuits and the selection of hydraulic valves. could redesign the hydraulic manifold to match their equipment. also readily paid the development cost. 1 month later, sent the hydraulic manifold samples. 2 months later, said that after their rotary tiller was installed with hydraulic manifolds, it was responsive during operation. The operation was more than 20% higher than before, and the fuel consumption was also reduced by 20%. The customer feedback was good, and more and more customers came to try it out. told me privately that he had seen his boss's long lost smile. The boss paid more and more attention to him. He will be promoted to the management next month. hydraulic manifold has 3 advantages 1. engineers have experience in hydraulic manifold design, especially in oil circuit design. Ensure flow distribution as required, eliminate bypass throttling loss and reduce energy loss.

90% of the people do not know hydraulic valves. How does persist for 13 years To be sure, there are many small and medium-sized factories with their own proprietary technologies , such as industrial products manufacturers with their own traditional technologies such as hydraulic valves. It is unlikely that will in 30-50 years, although consumables are gradually being replaced. Therefore, I am optimistic about hydraulic valve manufacturers, especially those with some proprietary technology. Over the past 13 years, has adhered to 3 lines: R & D, innovation and manufacturing capacity: 1. Hydraulic Valves maintain the trend of being specialized and strong. I call it both specialized and strong. Instead of giving priority to the development of manufacturing scale, we invest money in the research and development of hydraulic valves, spend time on the innovation of hydraulic valves, and spend energy on the manufacture of hydraulic valves. Most of the manufacturing industries have learned too many lessons from big to die. 2. focuses on the R & D and innovation of hydraulic valves. It focuses on both technology and quality, and strives to be strong on both sides. Its quality benchmarks the international first-line hydraulic valve brands. The performance and function of some hydraulic valves have exceeded the domestic head hydraulic valve manufacturers, especially in the vertically segmented niche market, such as high-pressure hydraulic valves. 3. Although the production scale of Hydraulic Valve maintains the original situation, there is still room for urgent orders and special orders of old customers. For industrial products, especially machine parts such as hydraulic valves, in marketing, you will find that it has nothing to do with the theories of Trout and Kotler. hydraulic valves adhere to: Focus on large hydraulic valve products and become our own core competitiveness. The manufacturing quality of hydraulic valves, the price positioning of hydraulic valves, and the target customers constitute a triangle of a manufacturing enterprise. Marketing, promotion and sales constitute a triangle of hydraulic valve business. I have always called on hydraulic valve manufacturers to improve the material grade and produce high-quality hydraulic valves, but few hydraulic valve manufacturers follow suit. Why Because the manufacturers of hydraulic valves have extremely fierce price competition, even if you do it, you may not be able to make money after all the hardships. However, hydraulic valves are used by 7 of the world's top 500 companies. For 9 consecutive years, hydraulic valves have been hydraulic valves. Moreover, hydraulic valves never do market common quality, price comparison and credit business. In the face of such a competitive hydraulic valve market

Is scientific research and innovation one way or two different ways hydraulic valve analyze it like this In the field of industrial products, has made rapid progress in recent years, with many proud scientific research achievements and patented technologies. In the hydraulic valve industry, hydraulic valve manufacturers have also begun to export, in these two years. Each hydraulic valve manufacturer has Many hydraulic valve manufacturers confuse the concepts of scientific research and innovation. Generally speaking, hydraulic valve scientific research is to convert money into hydraulic valve knowledge, which is a department that spends money, while hydraulic valve innovation is to exchange knowledge for money and create wealth for enterprises. They cannot be confused. Some scientific research institutions have only completed scientific research, but rarely completed innovation. It is a pity that some hydraulic valve manufacturers in the world have invested a lot of money in research and development, but they are only immersed in theory and have not become innovative pioneers in the industry.

The economical, efficient and reliable hydraulic manifold block design convinced Achilleas completely Achilleas comes from a Greek hydraulic equipment company. One of their rollers was complained by users because of oil leakage. After sales personnel found that there was a large gap in the valve block used for hydraulic manifold, which was the root cause of oil leakage. After further disassembling the hydraulic manifold, it was found that there were cracks in the lower left and right corners of the valve block. They thought that the problem can be solved by replacing the valve block. However, after 2 months of construction, the old problem was happened again. The engineer asked Achilleas to consult the original hydraulic manifold manufacturer. The manufacturer was not sure why the valve block broke within 2 months. Achilleas was helpless. Achilleas realized that he could only contact for help, because he also sent the inquiry for this hydraulic manifold to before. At that time, proposed to modify the oil circuit and hydraulic valve selection, but it was not accepted by their engineers. I was not surprised to receive his email. At the inquiry stage last year, our engineers found that there was an energy conflict between the oil circuit aperture of the hydraulic manifold and the selected hydraulic valve, resulting in the frequent instantaneous pressure rise of the hydraulic system. In particular, the oil circuit wall thickness at the left and right lower corners of the valve block is not enough, so it is not surprising that the valve block is cracked. This time, Achilleas didn't go to their engineers to verify. redesigned the oil circuit, re selected each hydraulic valve, and sent the hydraulic manifold block sample after 30 days. Last week, Achilleas sent an email saying that after replacing with sample for such a long time, there was really no problem. Moreover, the total price was saved by 20% compared with the original one, and the customer feedback that the action sensitivity was also improved a lot. This time, even their engineer also suggested that the boss should give the design and production of the hydraulic manifold block to in the future. He also wants to know why is so good I told him that the most important thing in the design of the hydraulic manifold block is to determine the operating parameters of the hydraulic system, understand the requirements of the system for the maximum working pressure and maximum flow, and reasonably design the oil circuit. Secondly, the pressure drop of the valve must be considered to ensure that the pressure drop through the pressure valve, flow valve and directional valve is not too high, which will affect the load action and cause the pressure problem of the valve block. has more than 20 years of industry experienced professional engineer from , who have unique experience in the design of hydraulic manifold blocks, especially

hydraulic valve has a bench department without KPI, but it is a special team in my heart hydraulic valve also has a similar department, but it is called bench department. This department has no short-term KPI and no KPI catch-up. Like an engineer's paradise, hydraulic valve engineers dare to keep trying and optimizing with such an environment. In hydraulic valve, the sales department makes today's money, the production department makes tomorrow's money, and the bench department makes the day after tomorrow's money. Conversely, the bench department is wasting today's money, spending tomorrow's money to do development for the sake of hydraulic valve strategy and the future of hydraulic valve, although the future is not clear, in my mind, they are the "special team" of hydraulic valve. Making high-quality hydraulic valves can only be driven by technology. A combat team composed of several people can anchor and conquer a technical direction. The subdivided STG focuses on innovative solutions for hydraulic valves. There has never been a shortcut or a fast track for the scientific research of hydraulic valves. Only when we settle down to do things, can we make every step steady. The reason why science and technology in this world can be developed is precisely because of the engineers' persistence, which is a long-termism and a bench spirit. hydraulic valve is used in aircraft. It sounds very powerful. But it's really hard to do. Sometimes you can't see the way. Sometimes, there are many roads in front of you. Fortunately, hydraulic valve chose the right path. Even if the road is tortuous, even if the road is very hard. But the right way is never far away. The bench Department of hydraulic valve has to make a hard hit on this road every day. Diligence is a way to explore talents and a necessary condition for success. engineers have experienced for many years. It is not difficult to combine, mutate and graft some hydraulic valve structures to create some new hydraulic valves. Instead of making some so-called patents that can't create any value for no reason, it's better to use your limited life to do something that can leave a mark on this beautiful planet. At that time, when I am old to die, on my deathbed, I will think that I have lived for so many years and made so many devices to run on the earth, which is enough to make me smile in the underworld. Bless the engineers of hydraulic valve. May you have the bench spirit to conquer one mountain after another. I also wish hydraulic valve a happy journey. hydraulic valves, the right way, never afraid of far.
