Valves

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. Scott sent an inquiry for hydraulic manifold blocks last week and said that the exhibition effect was good. After two rounds, we finalized the price of hydraulic manifold blocks and confirmed the production time of 100 hydraulic manifold blocks. I asked in private why he chose to purchase hydraulic manifold blocks from AAK. Scott told me 3 points, which encouraged me a lot: 1.I contacted more than 10 new hydraulic manifold manufacturers, but all of them answered "No", while AAK gave us the direction to solve our problems. I felt that AAK is not short-sighted and thinking about doing business rightly with heart. 2.Although the hydraulic manifold block of AAK is 12% more expensive than its peers, the tested service life is 60% higher than that of the original manufacturer. 3.The quality parameters of AAK hydraulic manifold blocks have been on par with those of local manufacturers in the United States. There are 2 data that surpass local manufacturers. The prices are more than 30% cheaper and the delivery time is also fast. AAK can well complete our overseas procurement strategy. AAK, dedicate to hydraulic valves and hydraulic manifold blocks a lifetime. You can also have a small try! https://www.aakindustry.com/info-detai , l/hydraulic-manifold-blocks-aak218

No matter which hydraulic cartridge valve manufacturer, there are only two dimensions to it: one is to ensure the manufacturing quality of hydraulic cartridge valves, and the other is to serve hydraulic cartridge valve customers well. The former deals with things, while the latter deals with people. Whether it's with people or things, they can't do without specific things. In fact, there are only 3 types of things: big things, small things, and trivial things. AAK's understanding of these 3 types of things is: ability for big things, attitude for small things, and pattern for trivial things. The ability of hydraulic cartridge valve manufacturers is hidden in big things, the attitude of hydraulic cartridge valve manufacturers is hidden in small things, and the pattern of hydraulic cartridge valve manufacturers can be seen in trivial things. Faced with different things, the true capabilities and attitudes of hydraulic cartridge valve manufacturers will be demonstrated. The ability of hydraulic cartridge valve manufacturers is the fundamental foundation for their standing. Ability is not just a simple process or processing, it is also a comprehensive quality of hydraulic cartridge valve manufacturers, not only manufacturing quality, but also service. Other hydraulic cartridge valve manufacturers cannot solve it, but AAK can. This is AAK's manufacturing capability. Other hydraulic cartridge valve manufacturers cannot gain the trust of customers, but AAK can, this is due to AAK's daily dissemination ability. A single action is better than a hundred thoughts. A strong manufacturer relies on action every day. In big things, one hides abilities, while in small things, one sees attitudes. Be serious and responsible in small things, with a correct attitude, so that you won't be perfunctory when encountering big things. A sense of responsibility is a prerequisite for doing small things well. For example, AAK has been adhering to 1 reminder, and 4 protective packaging for 11 years on small batch trial orders of express shipments. There has never been a packaging rupture or damage to hydraulic cartridge valves, and most hydraulic cartridge valve manufacturers, when problems arise, shift the blame to package shipping. AAK insists on treating every small matter as a major event, completing it with dedication, and continuously improving the manufacturing quality of hydraulic cartridge valves and customer experience capabilities. Do every small thing well, not forget our original intention for temporary gain or loss, and not lose our principles for temporary gain or loss. Serious work and sincere treatment of people are the values of hydraulic cartridge valve manufacturer AAK. A drop of water reveals the sea, and trivial matters are the details of hydraulic cartridge valve manufacturers. Although they may seem insignificant, they can reflect the pattern of a hydraulic cartridge valve manufacturer. When facing trivial matters, it is necessary to have a grand perspective to view the problem, rather than getting stuck in trivial details. When a person stands tall enough, they will not be bound by the small things in front of them. Faced with various trivial matters, don't worry, don't be afraid. One of our Fortune 500 clients has been testing orders at AAK for 3 years, each time with customized hydraulic cartridge valves for 5-10 pcs. We don't look down on small quantities or multiple batches of testing orders, and a few years later, they became our second largest customer. The hydraulic cartridge valve manufacturer AAK in China, improves their capabilities in major matters, hones their attitude in small matters, and amplifies the pattern in trivial matters.

Gallagher is from a hydraulic equipment manufacturing company in Brazil. His purchase has been smooth, but a hydraulic cartridge pressure control valve stumped him. In the second half of last year, they purchased high-pressure hydraulic cartridge pressure control valves for hydraulic power units. About half a year later, a customer complained that the hydraulic cartridge pressure control valve was leaking. According to the feedback from the original hydraulic cartridge pressure control valve manufacturer, the leakage was caused by ultra-high pressure 450bar and it can only be replaced with new one. Gallagher realized that the service life of the hydraulic cartridge pressure control valve produced by the original manufacturer was only 6 months, and the customer required at least 1 year. Gallagher contacted other cartridge valve manufacturers, but none of them was able to guarantee the service life of 1 year for the hydraulic cartridge pressure control valve that is resistant to ultra-high pressure of 450bar. Gallagher was worried. Gallagher found AAK website on B2B, noticed many customer cases related to hydraulic cartridge pressure control valves, and sent an email asking: Can AAK ensure that the hydraulic cartridge pressure control valve withstand ultra-high pressure 450bar working condition, and the service life is more than 1 year? According to the hydraulic system schematic diagram and the original production drawing of the hydraulic cartridge pressure control valve, AAK engineers found that the pressure relief method has a great impact on the valve, will consume the valve life, and is easy to leak. Gallagher asked AAK to make samples. After 35 days, AAK delivered 30 hydraulic cartridge pressure control valves. Last week, Gallagher informed us by email that AAK hydraulic cartridge pressure control valves had been used for 9 months, and no customer complained about leakage. The boss asked to purchase in bulk from AAK to replace the original hydraulic cartridge pressure control valves. I told him that 1 year's life is our basic requirement. He told me that his boss valued the service life of AAK hydraulic cartridge pressure control valve. The other cartridge valve manufacturers can only guarantee a service life about 6 months, while AAK could last more than 1 year. The pressure relief mode of this hydraulic cartridge pressure control valve, is optimized from the following 3 points: 1. The valve body of the hydraulic cartridge pressure control valve is divided into the upper valve body and the lower valve body, and then sealed and fastened with bolts to form the valve body. One end of the valve hole of the upper valve body is used as the pressure fluid inlet, and one end of the valve hole of the lower valve body is used as the pressure fluid outlet. 2. The valve hole of the upper valve body is close to the contact surface of the upper and lower valve bodies to form a variable diameter hole section larger than the diameter of the valve hole, and a sealing ball is set in it. The sealing ball is located on the valve hole port of the lower valve body. The sealing ball and the valve hole port of the lower valve body form a sealing pair. The upper part of the sealing ball is a return spring located in the variable diameter hole section. 3. The valve hole on the lower valve body is a folded hole composed of a vertical section and a horizontal section. The lower bottom surface of the lower valve body is provided with a control hole which is connected with the vertical section of the folded hole and coincides with the axis. The optimized hydraulic cartridge pressure control valve, when the piston rod of the hydraulic cylinder rises, the piston rod lifts the sealing ball, and the valve is in the state of pressure relief. The pressure relief medium flows out from the pressure fluid inlet along the valve hole through the spring, sealing ball, and pressure oil outlet to realize pressure relief. When the piston rod moves down, the sealing ball moves down to form a seal with the valve hole port of the lower valve body and stop pressure relief. This pressure relief method is conducive to the service life of hydraulic cartridge pressure control valve, which is guaranteed for 1 year. AAK hydraulic cartridge pressure control valve, ultra-high pressure 450bar, and safe for 1 year, welcome to try it! https://www.aakindustry.com/info-detail , /cartridge-pressure-control-valves- aak470

AAK hydraulic valve blocks are processed with compound cutting tools, and the production efficiency is nearly 50% higher than that of peers. At the same time, the precision of hydraulic valve blocks is also improved by 5%. AAK completed the urgent order of 1,000 hydraulic valve blocks in only 30 days, while most hydraulic valve block manufacturers can't control the processing technology of compound cutting tools. German customers are also attracted by it. It's a little strange that since the second half of last year, many inquiries about hydraulic valve blocks have an urgent delivery date. They need to be shipped within 20 days or finished within 30 days. For non-standard hydraulic valve blocks, from production drawing design, sample, life test, production to delivery, the vast majority of hydraulic valve block manufacturers need 45-60 days. But this is desperate for the customers with urgent order of hydraulic valve blocks, and Bach in Germany is one of them. Bach wanted to purchase 1,000 pcs of hydraulic valve blocks a few weeks ago. His customer requested that the goods be delivered to Germany in 50-60 days, but the quotation of the local factory in Germany exceeded his budget. He could only find the manufacturer of hydraulic valve blocks in Ningbo, that is, goods need to be shipped in 30 days. Bach contacted nearly 20 hydraulic valve block manufacturers, but none of them can complete the production of 1,000 hydraulic valve blocks in 30 days. A few days ago, we received Bach's message on AAK website (www.aakindustry.com): I saw an article on B2B that "AAK processes hydraulic valve blocks with compound cutting tools, and the delivery time is 30 days faster than peers". Can AAK complete non-standard hydraulic valve blocks in 30 days? After communication, I learned that Bach was troubled by the delivery date of hydraulic valve blocks. I directly told him that the 30 days of lead time for 1,000pcs of hydraulic valve blocks is enough for AAK. AAK adopts the compound cutting tool processing technology that most hydraulic valve block manufacturers can't control, that is, combining two or more similar or different types of hole processing tools into a special composite 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 chamfering and external counterbore, which greatly improve the processing efficiency and have the characteristics of high efficiency, high precision and high stability. This is the "trump card" of AAK to improve the production efficiency. The production efficiency is nearly 50% higher than that of its peers. At the same time, the precision of hydraulic valve blocks is also increased by 5%. Five days later, the hydraulic valve block sample was successfully sent out. Less than a week later, Bach told AAK that the test results of the hydraulic valve block made him admire. The technical parameters of AAK hydraulic valves have caught up with the local factory in Germany, but the price is 30% cheaper, and the delivery is more than 30 days faster. The sample was approved for mass production at the first time, and the hydraulic valve blocks were shipped smoothly after 30 days. AAK hydraulic valve blocks, processed with compound cutting tools are not only fast, high precision but also stable. You are welcome to try the order. https://www.aakindustry.com/info-det , ail/hydraulic-valve-blocks-aak217

A while ago, Basel from Spain left a message on the website of hydraulic cartridge valve manufacturer AAK: Can you GUARANTEE that the cylindricity of the cage of the hydraulic cartridge valve is controlled within 0.3µm, and the accuracy of within 2μm? With the word“GUARANTEE” capitalized, I can feel Basel's emotions, he should have received promises from other hydraulic cartridge valve manufacturers, but he has been hurt. After communication, it was learned that Basel had tested the samples from a hydraulic cartridge valve manufacturer in Ningbo China. The 6 testing samples passed the requirements of 0.3µm cylindricity and 2μm accuracy for the valve cage. However, the 480 pcs of shipment had accuracy issue. That is to say, the machining accuracy of the original hydraulic cartridge valve manufacturer is unstable. For hydraulic cartridge valve cages with high precision requirements, subsequent honing is crucial. The consistent thinking of hydraulic cartridge valve manufacturer AAK is a 3-step process: what has been done, why is this done, and what else needs to be done? For the honing of the hydraulic cartridge valve cage, AAK has an automatic control honing machine SUNNEN from the United States. The equipment is equipped with a SAC size automatic control system. When the honing accuracy meets the system requirements, it can automatically stop, especially with the setting of oil and stone slow advance, providing assurance for the surface roughness and cylindricity of the hydraulic cartridge valve cage. Our technicians first match the corresponding fixtures based on the external contour of the hydraulic cartridge valve cage. Then fit the hydraulic cartridge valve into the equipment, and the equipment can automatically perform honing. This is our first step, making fixtures and then grinding. Why do we have to do this? Most hydraulic cartridge valve manufacturers prefer to use universal fixtures that come with their equipment, but AAK focuses on customizing fixtures based on the hydraulic cartridge valve cage, in order to achieve high-precision stability. What else does AAK do? After honing the valve cage of the hydraulic cartridge valve, compare each valve cage with a plug gauge. If it is not qualified, it will be discarded. Most hydraulic cartridge valve manufacturers in Ningbo China may not have this detail. AAK hydraulic cartridge valve, the consistent thinking of always takes 3 steps, you can also give it a try!

For hydraulic cartridge relief valves with precise small holes, most of manufacturers encountered penetration when processing the Φ4.5H7、Φ4.7H7 holes. AAK used 3 advantages, which not only prevented penetration for 100%, but also reached R0.2mm at the bottom of the small holes. After receiving the samples of AAK hydraulic cartridge relief valves, Arvin sent a PO for hydraulic cartridge relief valves of 20,000 dollars. Precise small holes of hydraulic cartridge relief valves is a difficult problem in machining. The vast majority of hydraulic cartridge valve manufacturers have difficulty in controlling the processing tools, cutting parameters, cutting stress and processing technology, resulting in easy deformation of components or substandard accuracy. What's more, it is unstable. For example, the precision of the small holes of this batch of hydraulic cartridge relief valves reached the standard, but the next batch has hidden dangers. The most taboo about the quality of industrial products is instability. Arvin is from a hydraulic company in the United States. Recently, he was overwhelmed by a hydraulic cartridge relief valve with high requirements for machining accuracy and form and position accuracy. He selected a hydraulic cartridge relief valve manufacturer cooperated for 4 years to make samples. The samples were made by 3 times, but all failed, and the accuracy was not improved again and again, but was good and bad. Arvin had to give up this old supplier and contacted 20 hydraulic cartridge relief valve manufacturers. They either did not reply or gave up directly. Arvin found AAK hydraulic valves in B2B and left a message: Can you customize the hydraulic cartridge relief valve with precise small holes? After communication, I learned that he was troubled by the difficult machining of precision small holes of hydraulic cartridge relief valve. According to the parameter requirements of hydraulic cartridge relief valve, the hardness, wear resistance, corrosion resistance and surface treatment, all requirements are very high. After half a day of discussion, AAK technical team came up with the process plan. I told Arvin that AAK was 90% sure to solve the problem, and the standard deviation (Sigma) accuracy of size could be stable in different batches. 2 days later, Arvin asked me to make samples. After 30 days, AAK sent 6 hydraulic cartridge relief valves. 12 days later, Arvin returned a PO for the hydraulic cartridge relief valve worth 20,000 US dollars. In order to improve and stabilize the holes accuracy of hydraulic cartridge relief valve, AAK optimized 3 points: 1. Processing equipment: It is easy to process the hole into a taper hole by conventional grinding. The Swiss precision lathe is the first choice for processing the precision small holes of this hydraulic cartridge relief valve. 2. Tool and tool parameters: Six tooth 1201/4.6H7 and 1201/4.8H7 reamers are used as finishing tools, and the tool tip is grinded to R0.2mm to avoid penetration. 3. Fixture improvement: In order to ensure the state of precision holes during semi finishing, AAK uses self-made floating spring chuck to hold the reamer, avoiding horizontal axial or vertical space errors, which is conducive to precision and better standard deviation. AAK hydraulic cartridge relief valve precision small holes, only 3 steps to ensure quality, welcome to try! https://www.aakindustry.com/info-detai , l/hydraulic-cartridge-relief-valves- aak402

This morning, Joselito sent an email asking about the production time of 1,000 hydraulic manifold blocks, which surprised me a little, because in the past two years, Joselito has basically placed orders for just hydraulic valves only, but very few for the hydraulic manifold blocks. Joselito is a purchaser of BEZARES company in Spain. We met 2 years ago. After communication, it was learned that he encountered problem on the hydraulic manifold blocks purchased this time. A batch of hydraulic winch equipment of their company was complained by some users that the winch was often weak. Their after sales found that the hydraulic manifold block was leaking. Because of the purchase cost limitation, he disassembled the hydraulic manifold blocks and purchased them separately from 3 hydraulic valve manufacturers. Now the leakage problem of the hydraulic manifold blocks has come, all 3 manufactures prevaricate and are not responsible for the oil leakage of the hydraulic manifold blocks, they thought that the problem was caused by the unreasonable design or the wrong installation method of the hydraulic manifold blocks. The engineer checked the hydraulic manifold blocks one by one and found different problems, some sealing ring was broken, some gasket at the interface was worn, and some has iron filings in the valve hole. In the past year, a lot of money, labor and maintenance costs were spent on the after-sales for the hydraulic manifold blocks. Now the customers are not satisfied with their after-sales performance, and the boss is not happy to spend the after-sales money indiscriminately. Joselito has a big headache. AAK suggests that Joselito should purchase the whole hydraulic manifold blocks in one factory as much as possible, because each hydraulic valve manufacturer has different quality positioning. AAK has now received more and more inquiries for hydraulic manifold blocks, including Skyjack, a Canadian listed company, and Brevini, a top company in the field of transmission. Joselito finalized the purchase contract of the hydraulic manifold blocks with AAK in two rounds, and required that AAK hydraulic manifold blocks should not be reported for repair within 1 year. It is not only the hydraulic valves and hydraulic manifold blocks produced by AAK with quality assurance, but also 3 points that are difficult for peers to do well: 1.AAK shall deeply clean the hydraulic manifold blocks before assembly to ensure that it is 100% free of iron filings, dirt and other impurities. 2.Only technicians with more than 10 years of experience are qualified to assemble, check the matching between the duct and the hydraulic schematic diagram, and test the accuracy of each duct to ensure that the sealing ring of the hydraulic valves will not be damaged. After assembly, use the test bench to debug the hydraulic manifold blocks for many times, including pressure test and function test, to ensure that the action function of the circuit is accurate and reliable. Such technicians and such operation procedures may not be found in the 3rd hydraulic valve manufacturer in Ningbo. 3.AAK technical team has engineers from the world's top 500 hydraulic manifold block enterprises. They have their own experience in material selection, production drawing design and production line quality control. AAK hydraulic manifold blocks are not only professional, welcome to have a small try! https://www.aakindustry.com/info-detai , l/hydraulic-manifold-blocks-aak216

Paul is an old customer and also an old friend of ours. He has been purchasing hydraulic cartridge valves from AAK for 7 years. He is a China expert. He used 3 "troubles" in his email on Friday. The thing is, AAK has developed a high- precision hydraulic proportional valve for him, which has already taken 5 months, and cannot fully match the standard parts of HydraForce. Paul is also a bit worried. He knows that if AAK cannot succeed with this hydraulic proportional valve, he can only purchase SUN hydraulic proportional valve standard parts at a higher price of over 70%. His email is as follows: First of all, I apologize for causing AAK in trouble for 5 months. (Paul, very friendly and gentle). What troubles do you have in development? Do you need any help from us? (Paul, very patient and helpful). Don't worry about causing me trouble. If you have a need, just speak up (Paul, very kind and thoughtful). Looking at the 3 troubles in his email, I felt very touched and went back to my childhood. My mother always said to me, "Being in society, try not to cause trouble for others.". My mother is very traditional. Now consider that some Chinese style family education has drawbacks. Parents always educate their children to avoid causing trouble to others outside. From Paul's email, I learned that actually getting into trouble with each other is the beginning of interaction. They trouble each other, but know how to be grateful, and when they come and go, they have a relationship. Over time, this interaction creates an intimate relationship. This is the cornerstone of "mutual trouble, interaction begins". Without gratitude, it is difficult to interact, let alone be intimate. Dare to trouble others, and you may encounter noble people. But the foundation for meeting noble people is to know how to be grateful. The most effective interpersonal communication is to "ask for help" and then give the other person a hidden compliment, potentially acknowledging that the other person is better than yourself. This is an act that everyone instinctively wants and likes to accept. After all, hoping respect, acknowledge, and value from others is the greatest weakness of human nature. But troubling the other person is limited, and you cannot let the other person sacrifice themselves to fulfill you, especially at the beginning of the relationship. This is the red line for "troubling each other and starting interaction.". "Request for help" involves questions that are best dealt with by the other person's expertise and that are a matter of no effort. When the other person has helped, you should immediately express gratitude in full appreciation, making the other person feel that they owe you something. This is the correct attitude in dealing with people. AAK hydraulic cartridge valve, mutual trouble, the start of interaction.

Kearney comes from Türkiye. He had an order for a customized hydraulic manifold with 3μm accuracy that needs to be delivered within 40 days. Due to high accuracy requirement and tight delivery, no manufacturer was willing to accept the order, which is very troublesome for him. At the beginning of this year, their old customer customized a hydraulic power unit, which was quite urgent. The hydraulic manifold for the power unit must be delivered within 40 days. Kearney contacted more than 10 hydraulic manifold manufacturers, but they either could not achieve the accuracy or could not complete it within 40 days. Kearney was very anxious. Kearney found AAK on Google and left a message on AAK website: Can AAK finish a hydraulic manifold with 3μm accuracy within 40 days? At the same time, he provided us the machining drawings of the hydraulic manifold. Although the hydraulic manifold is difficult to process and has high accuracy, AAK has Aigema machining center, and also has the historical experience of completing customized hydraulic manifold test orders in 30-35 days. Kearney saw hope and requested AAK to make samples immediately. 35 days later, AAK sent out 5 hydraulic manifold samples. Yesterday, Kearney sent us an email to place a re-peat order for 100 hydraulic manifolds. Their hydraulic power unit equipment has been recognized by their customer, and their engineers are also satisfied with the accuracy of AAK hydraulic manifolds. Kearney privately told me that his boss praised him for finding a high-quality and efficient manufacturer of hydraulic manifolds in China. This hydraulic manifold is processed by AAK using Taiwan Aigema machining center, which has the advantage of three-axis track and guaranteed accuracy. The setting of dual guide rails ensures that the Z-axis does not shake during rapid movement, ensuring that the machining accuracy is controlled within 3μm. The three-axis movement speed can reach 48M/min, which is more than 50% faster than most machining centers, ensuring that AAK can complete the trial order in 35 days, while the other hydraulic manifold manufacturers in Ningbo China require a delivery time of more than 40 days. This device also has another advantage: it can automatically remove chips. AAK hydraulic manifolds, give you not only 3 benefits. You are welcome to try it out.

At 05:10 this morning, I was listening to music and browsing emails. Billy, who had no news in 9 months, sent an email. Without reading the email, I could guess that the hydraulic check valve developed by AAK for 3 months last year had a result. Opening Billy's e-mail and it is an annual order of 5,000 hydraulic check valves at one time, with about 500 hydraulic check valves delivered every month. Billy is from a hydraulic equipment company in the United States, he has purchased a small number of high-pressure resistant hydraulic check valves from AAK in the past. At the beginning of last year, his company received complaints from a customer that its high-power bulldozers were prone to weak starting of the hydraulic system after being used in less than half a year. The after-sales engineer found that the hydraulic check valves leaked and can not maintain the pressure and caused the problem. Billy contacted the original manufacturer of the hydraulic check valves, and manufacturer advised that the system pressure of the high-power bulldozer exceeded 450bar, and the opening and closing frequency was also high. When the hydraulic check valve was in the high-pressure state above 450bar, the valve spool was worn quickly, and the service life could only be guaranteed as 1 million times. Therefore, it was normal to replace the hydraulic check valves every half a year. If you want a hydraulic check valve with a service life of 2 million times, you can only purchase it from German HAWE. Billy has no choice but to make do with the hydraulic check valves of the original manufacturer first, but the after-sales cost every half a year is really unbearable. Maybe other manufacturers can offer hydraulic check valves with service life more than 1 million times. Billy began to contact other factories, including AAK. After receiving Billy's email, AAK engineers had reached a conclusion according to the hydraulic check valve drawings and bulldozer working parameters. In order to exceed the service life of 2 million times of the hydraulic check valves, we can only test new high-pressure resistant materials. We replied Billy at that time that according to the existing steel options of AAK, what your original manufacturer said was right, it can only guarantee the service life of 1 million times of the hydraulic check valves. However, we are confident to develop the one of 2 million times, because we have our own R & D experience in anti-high pressure. Billy replied directly that AAK would be given 3 months to sample the hydraulic check valves with pressure resistance above 450 bar. He also frankly informed that two other hydraulic check valve manufacturers were also making samples. If all manufacturers fail, they can only buy high-pressure hydraulic check valves from German HAWE. Three months later, AAK successfully sent 20 hydraulic check valve samples to Billy. Nine months later, the email came from Billy today. Billy noted the sample testing results in the email. The bulldozer equipped with AAK hydraulic check valve was still normal after 9 months, while the hydraulic check valves from another two manufacturers were eliminated in the 6th and 8th months. AAK hydraulic check valve has a pressure resistance of more than 450 bar and a service life of more than 2 million times, because: 1.AAK has engineer who have worked in the Shanghai factory of German HAWE for 11 years and has experience in high pressure resistance. 2.We have tested more than 20 kinds of steel and selected the most suitable 35CrMo steel to produce the valve spool of this hydraulic check valve. 3.Good materials also need good processing. The heat treatment method adopted by AAK for 35CrMo alloy steel is 845 ℃ annealing, 860 ℃ quenching (oil quenching) and 200 ℃ low temperature tempering. After this special heat treatment, its hardness and wear resistance are increased by at least 50%. AAK hydraulic check valve, can resist pressure of more than 450bar, you can also have a small try! https://www.aakindustry.com/info-detai , l/hydraulic-check-valves-aak215

This week, we’d like to introduce a hydraulic solenoid cartridge valve equivalent to HydraForce SV08-45. It is a solenoid-operated, 4 way, 2 position, direct-acting spool type, screw in hydraulic cartridge valve. In January of 2023, we received an inquiry from a Russian customer for a hydraulic solenoid cartridge valve equivalent to HydraForce SV08-45. Per customer, they have received quotes and samples from several hydraulic cartridge valve manufacturers in Ningbo China. But they are not satisfied either with quality of their product, or with the price level. They hope that AAK can be the one of good combination of reliable quality and reasonable price. After quoting, we were advised that AAK price is not competitive, but they’d like to make a decision after testing the samples. In December, the last month of 2023, we were very happy to know that this customer decided to place the order with AAK. Although AAK price is not competitive, the service life of AAK samples is the longest one among of those hydraulic cartridge valve manufacturers.   AAK hydraulic solenoid cartridge valve E-SV08-45 two advantages: 1. The function and performance is equivalent to that of HydraForce 2. Its service life is 2 times that of its domestic peers Technical parameters of AAK E-SV08-45 solenoid cartridge valve: Max. Operating Pressure: 207 bar (3000 psi) Flow: 11.4 L Internal Leakage: ＜82ml/min at 207 bar (3000 psi) Cavity: VC08-4 AAK E-SV08-45 hydraulic solenoid cartridge valve, benchmarking HydraForce SV08-45, its service life is 2 times that of its domestic peers.

Last Friday, James emailed that he would place an order for 1,200 hydraulic threaded cartridge valves for his last inquiry. This is the PO he sent to AAK after visiting 6 China hydraulic valve factories. It is a little surprised the first cooperation is 1,200 hydraulic threaded cartridge valves. James is from Spain. At the beginning of last year, he was assigned by the headquarters to the Guangzhou office to be responsible for the purchasing from China hydraulic valve factories. In early March, James sent an email saying that the epidemic policy of Ningbo can accept visitors. For the hydraulic threaded cartridge valve quoted last time, the headquarters asked him to visit the China hydraulic valve factories before placing an order. He planned to visit China hydraulic valve factories in Ningbo a few days later. AAK hydraulic valve is his first stop. Three days later, James came to AAK hydraulic valve and asked to visit the workshop directly instead of the office. I took James to visit the whole production line of AAK hydraulic valve, from the first raw material inspection to the processing of hydraulic threaded cartridge valves, including heat treatment of semi-finished products, rough machining, finishing, cleaning, inspection of parts, assembly, inspection, packaging, warehousing and other processes. We also introduced the equipment and processing advantages and characteristics of AAK hydraulic valves. He looked the fixtures modified by ourselves for a long time. Two hours later, James said he would go to other China hydraulic valve factories and left AAK. I'm not sure how many days he stayed in Ningbo and visited how many China hydraulic valve factories. I didn't know about his trip to Ningbo until his email last Friday. He visited 6 China hydraulic valve factories. I asked James why he chose AAK hydraulic valve to place an order after visit 6 China hydraulic valve factories and placed such a large order directly to AAK suddenly. James replied that AAK is the most distinctive China hydraulic valve factory in China he has seen, mainly including the following details: 1、AAK advanced Swiss imported CNC machine tools, honing machines, CNC precision automatic lathes and pressure test bench impressed him deeply, especially those modified fixtures, which have not been seen in other China hydraulic valve factories. 2、AAK has 6 senior engineers in the industry, especially the hydraulic valves in the high-pressure category, with the concept of German HAWE, which makes him feel at ease about quality. AAK inspectors used a strong spotlight to check the valve hole, which made him refreshing. In particular, a few of those whose finish does not meet the requirements are picked out, which shows that AAK is harsh on quality. He has never seen such detailed inspection in other China hydraulic valve factories he visited. 3、Although the hydraulic threaded cartridge valve of AAK is about 10 ~ 20% more expensive than the other 5 China hydraulic valve factories, he believes that the service life of AAK hydraulic valves is 1 ~ 2 times longer than that of them. China hydraulic valve factory, AAK has a cleanliness obsession in quality, which is even more QC than QC.

Adam, an old American hydraulic customer, sent AAK 3 emails consecutively on the same day last month, for the leakage of a hydraulic cartridge flow control valve. According to the picture he sent, the hydraulic cartridge flow control valve has a cut-off plate that is supported by a spring. Some customer complained that the hydraulic cartridge flow valve leaked without working. The original manufacturer of the hydraulic cartridge flow control valve cannot solve the problem in 3 months. Because the sales volume of this hydraulic cartridge flow control valve is very good, Adam wants it 100% no complaints. Through the pictures, it is difficult to trace the cause. I suggested Adam send us 3 samples of the original hydraulic cartridge flow control valves. After we received and checked the samples, we found that the leakage was more serious if we pressurized, but the tightness of the cut-off plate was no problem. We adjusted the spring, and the first pressurization did not leak, but after 3 times, the leakage occurred. It was basically judged that the spring has hidden danger. After the spring tension test, it was found that the spring is abnormal. 2 days later, we informed Adam of the hidden danger of the spring, and at the same time, we replaced the internal springs of the 3 hydraulic cartridge flow control valves with AAK springs, and returned the samples to him. 2 weeks later, Adam sent a PO for this hydraulic cartridge flow control valve, with a value of more than 30,000 dollars, and told us that the 3 returned samples were tested for 5 pressurizations, and no leakage was found, and the operating efficiency of the hydraulic system was also improved by nearly 10%. Adam privately ridiculed himself. He has been engaged in the hydraulic valve market for so many years, but still has to ask for help from AAK when there is a problem that he cannot solve. The main reason why AAK can effectively solve the leakage problem caused by springs, is to ensure the following 3 points: 1. We have our own spring source that has cooperated with us for 10 years, to avoid the phenomenon of unequal material between the sample and the production spring, and ensure the quality. 2. Equipped with spring tension and compression tester, reasonably select the spring with elastic coefficient within the standard range, to avoid leakage caused by elastic coefficient deformation. 3. A quality inspection department to ensure that the quality is qualified during assembly and prevent leakage. AAK hydraulic cartridge flow control valve, 3-step check on the spring, zero leakage, welcome to try! https://www.aakindustry.com/info-detai , l/cartridge-flow-control-valves-aak469

For a hydraulic valve manufacturer, if you produce hydraulic valve standard parts like your peers, without your differentiation or difference, you can only rely on a set of hard technical indicators of quality to make the market. I think this is the hard indicator of hydraulic valve manufacturing industry. The first thing for a hydraulic valve factory is quality positioning. I ask our engineers, workshop directors and technicians, even apprentices, to benchmark the global first-line hydraulic valve brands in terms of quality awareness, at least surpassing the quality of domestic first-line hydraulic valves. Otherwise, you are not suitable for hydraulic valve production in AAK. If you don't get the masterly skill really masterly, you are not qualified to enter the hydraulic valve market. With masterly skill, you have the confidence to produce orders for hydraulic valves from the world's top 500 enterprises. “Zhiliang”, also known as “Pinzhi”, is both quality in English. I don't understand why some hydraulic valve manufacturers have no differentiation, and the quality and technical indicators are strong neither. What does it depend on to win the world? Unless you cheat. Each industry has its own quality standards. At the same time, each product has its own enterprise quality standards, and the peers are different. This is the quality positioning. The positioning of AAK hydraulic valves is to benchmark the global first-line hydraulic valve brands. In recent years, AAK has never wanted to recruit new engineers, because it is very difficult to change an engineer's cognition, which takes 18 months, and it will take another 18 months for him to do it, totally 3 years, but maybe he left in the second year, and he had to say something he thought he was right. The manufacturing of hydraulic valves is exquisite. This characteristic is in the upstream of the manufacturing industry - materials, key parts, manufacturing equipment, etc. need long-term investment, continuous tracking and the awareness of excellence, which is also the embodiment of the "craftsman spirit". No matter how iterative the technical cycle of the hydraulic valve is, your skills must not age, the craftsman spirit must not be lost, and the masterly skill must be really masterly. The road of quality is just like practice Buddhism or Taoism. The practice of good people has to go through thousands of risks and obstacles, same as the difficulty of eighty adventurous experiences before Tang Sanzang finally got the real Buddhi , st scripture. In the first few years of AAK hydraulic valves, we had to take a detour. There are a lot of south walls to hit, pits to fall and tuition fees to pay. Maybe this is the growth of AAK. Growth is as painful as death, and the essence is also the same as death. It means the disappearance of old quality standards and the birth of new quality standards. Accept it, face it. Then, we can constantly upgrade and grow into what we expect. AAK hydraulic valves, quality is the highest principle. https://www.aakindustry.com/info-detail/hy , draulic-valves-aak213
