Patrick, an old customer in the Netherlands, used to buy our hydraulic cartridge valves. In the first half of the year, he purchased a batch of hydraulic valve blocks from another hydraulic valve manufacturer, but he had received a strange complaint from users in recent weeks. The hydraulic oil deteriorated suddenly. After stopping the machine to check the hydraulic oil, it was found that there were small iron filings inside the oil. After disassembling the whole hydraulic valve, it was found that the valve spool also showed signs of wear. The customer judged that there were iron filings in this batch of hydraulic valve blocks. Patrick discussed with the hydraulic valve block manufacturer about how to deal with this quality complaint. The manufacturer replied that it was the problem of hydraulic oil, not the hydraulic valve block. So this problem was stuck here. Patrick emailed me and asked if I knew this hydraulic valve block manufacturer and whether I could mediate and solve the problem. When I received the drawings of the hydraulic valve block purchased by Patrick this time, I felt that the iron filings probably came from the hydraulic valve block, because the intersecting processing channels of this hydraulic valve block were complex. With Patrick's appeal, I went to the hydraulic valve block factory. The overall feeling of the factory was still good, but the cleaning process before hydraulic valve block packaging did not accord with the process and details in my mind. When I came back, I emailed Patrick. The manufacturer should understand that the problem of iron filings lay with them. However, according to the current iron filings removal process in this factory, even if replenishment, it was difficult to completely avoid iron filings. So he didn't want to reproduce and couldn't solve the problem, he had to perfunctory your demands. Patrick didn't reply to my email for 2 days. When I asked him what else he needed me to do in this matter, he said that he had a big headache these 2 days. The owner asked him to find a new hydraulic valve block manufacturer to replenish part of the hydraulic valve blocks to take care of the customer's dissatisfaction with quality. I reminded him that there were few hydraulic valve manufacturers that could do this type of hydraulic valves with many slender holes. AAK HYDRAULIC VALVE solved a similar problem of iron filings of hydraulic valve block last month, and I sent him the pictures of hydraulic valve block for reference. The next day, Patrick asked us how long it would take to produce 200 hydraulic valve blocks, which was the minimum replenishment quantity required by the customer. When the replenishment order was confirmed, Patrick was relieved. How does AAK hydraulic valve remove iron filings from hydraulic valve block Firstly, the hydraulic valve block is boiled with high-temperature alkaline water to make the iron filings of the hydraulic valve block lose magnetism, and then
Hydraulic directional control valve troubleshooting, in only half of the time given by Leo, AAK HYDRAULIC VALVE used Fluororubber Sealing Ring and solved the problem of the hydraulic directional control valve troubleshooting that the other hydraulic valve manufacturers have not been able to solve, so that Leo can sleep at ease. This morning, just after reading the emails in the office and preparing for a cup of coffee, my colleague forwarded me an international express. I was a little surprised that there was no parcel notice from any customer, who sent the hydraulic valves to AAK? Will it be a complaint? I haven't met this for several years. I opened the package in fear. There are 5 new hydraulic valves inside. After simple inspection, they should be hydraulic directional valves. Looking at the sending address and person, it turns out that it belongs to the old customer Leo. This guy likes to make this sudden attack. Open the face book and I ask him, these are hydraulic directional valves. What do you need me to do? Leo said, hydraulic directional control valve troubleshooting, can you do it? I'm not good at the hydraulic directional control valve troubleshooting. He didn't reply. I immediately joked that I'm not good at the hydraulic directional control valve troubleshooting, which doesn't mean that AAK HYDRAULIC VALVE is also not good at the hydraulic directional control valve troubleshooting. AAK HYDRAULIC VALVE valve has its own technical team, which can help you on the hydraulic directional control valve troubleshooting. Leo commanded that I have 3 hours to go to bed. Give you 2.5 hours to finish the hydraulic directional control valve troubleshooting. I need to know where the hydraulic directional control valve troubles are and your solutions to the hydraulic directional control valve troubleshooting. After learning about his use scenarios of these hydraulic directional valves and media, I immediately asked AAK HYDRAULIC VALVE technical team to finish the hydraulic directional control valve troubleshooting within 2 hours. The AAK HYDRAULIC VALVE technical team simulated the use scenario of Leo's hydraulic directional valves under the pressurization and flow scenario. The test report came out soon. There were problems with the sealing rings of these hydraulic directional valves. At the same time, we suggested him use Fluororubber sealing ring to seal this hydraulic directional valve. We took 1.5 hours to finish the hydraulic directional control valve troubleshooting, which is just half of the time given by Leo. After learning the result, Leo was relieved and could sleep at ease. The story turned out to be this: Leo purchased some hydraulic directional valves, 30% of the hydraulic directional valves have flow parameter problems. The hydraulic valve manufacturer has not been able to have solutions to the hydraulic directional control valve troubleshooting. The boss is very unhappy.
The hydraulic needle valves produced by AAK has no leakage and its stability exceeds that of most of its hydraulic valve peers, enabling a foreign trade company in Guangdong to save a major global top 500 customer. The key is that AAK adopts high-precision processing equipment imported from Switzerland to produce hydraulic needle valves. At present, there are less than 5 hydraulic valve manufacturers with such high configuration in the hometown of hydraulic valves in Ningbo. Most hydraulic valve manufacturers use CNC lathe to produce hydraulic needle valves. The hydraulic needle valves made by CNC lathe has high technical requirements for operators and is prone to human errors, such as the valve spool deviates from the central axis. Because of human error, the hydraulic needle valve leaks, and it is not easy to judge which part has the problem. At the end of last year, Mr. Wang, the general manager of a hydraulic valve export company in Shanghai, received complaints from major customers about the several batches of hydraulic needle valves, which made them in a mess. Under the introduction of friends, he came to our company and brought those hydraulic needle valve samples with problems. After inspection, it is found that the main line of the hydraulic needle valve is offset, and the valve spool deviates from the central axis. I told him that this problem is easy to solve and also easy to cause problems. Only with a better CNC lathe can it be guaranteed. We provided him the test data of AAK hydraulic needle valves for comparison, and also asked him to take several hydraulic needle valve samples at random and send them to his customer to compare with the domestic peers. More than half a year later, there was still no reply from Mr. Wang. I didn't know how difficult it was for a top 500 enterprise to place a new order until I had a telephone communication with Manager Wang for more than 30 minutes last week. After Mr. Wang went back last time, he wanted to send the samples of AAK hydraulic needle valves to the major foreign customer, a global top 500 enterprises. At first, the customer refused until their overseas colleagues came to visit with the samples of the hydraulic needle valve to test the samples together on site. After the test, the customer was very satisfied with the quality of the hydraulic needle valve samples, which not only had good surface gloss, high precision, but also had strong sealing performance. Customer is willing to place a trial order first. As long as the quality of the mass production is the same as the samples brought, they can continue to purchase all kinds of hydraulic valves from their company. Mr. Wang asked us to work together to keep this global top 500 customer.
Under the pressure and flow conditions, AAK hydraulic valve effectively controls the sealing ring of each hydraulic valve, so it always ensures that the flow parameters in the hydraulic directional valve system are at the normal value. Only a small detail of the sealing ring has made the reputation of AAK hydraulic valve exceed that of many domestic and foreign peers. I will not modest about this. Many hydraulic valve manufacturers are used to domestic sales and are used to dogmatic production. Maybe they can copy the production process of their peers and continue to use some traditional technologies, but they may be helpless on the details or hidden problems of some spare parts. Leo, an old customer, suddenly sent me 3 samples of hydraulic directional valve some time ago. I didn't receive any email about these samples of hydraulic directional valve in advance. So I thought Leo asked us to offer a quotation. After receiving the hydraulic directional valve samples, I asked him by e-mail how many quantities he needs and what scenario this hydraulic directional valve will be used, then I would give him the plan of this hydraulic directional valve. However, Leo didn't need my quotation, just let me judge the quality of these hydraulic directional valves. Sending samples to let me just see the quality without doing other actions. This was the first time I had met. After testing these hydraulic directional valve samples, AAK HYDRAULIC VALVE technical team found the overall quality was good. The only hidden danger was that the flow parameters of one of the hydraulic directional valves were a little unstable, which should be adjustable in use. I directly told Leo that these hydraulic directional valves were qualified, but he should pay attention to flow adjustment during use. Leo's email reply surprised me again. Leo said that no wonder he stumbled in purchasing these hydraulic directional valves. Even AAK HYDRAULIC VALVE couldn't find problems with these hydraulic directional valves. I angrily asked the technical team to test these hydraulic directional valves again and simulate the use scenario of Leo's hydraulic directional valve under the pressurization and flow scenario. The test report came out soon. There were problems with the sealing rings of these hydraulic directional valves. Leo was relieved when he learned of the result and found the root of the problem. 30% of the hydraulic directional valves he purchased this time had the problem of flow parameters lower than the standard parameter values required by customers. His hydraulic valve manufacturer had been unable to find the root cause of the problem. He never thought it was caused by the mismatch of sealing rings. The traditional nitrile rubber sealing rings were not suitable for hydraulic scenes.
Mason, an old customer of hydraulic valves from the United States. In March this year, he was not satisfied with the quotation of one of our hydraulic valve blocks, which was nearly 7% higher than his target price, so he didn't place an order with AAK HYDRAULIC VALVE. Unexpectedly, he sent an email last week asking whether our quotation of hydraulic valve block in March was still valid. We replied that you were our old customer and the price must be valid. Mason also frankly told us that there was a problem with the hydraulic valve blocks he purchased, which made him very headache now. After communication, we learned that there were no problems in the preliminary test and shipment inspection on the hydraulic valve blocks produced by his previous hydraulic valve manufacturer. In the recent month, users had gradually reported that after setting up and debugging, the surface of the hydraulic valve block fell off paint, rusted, and even there was pollution inside the hydraulic system. Nearly 60% of the 300 hydraulic valve blocks purchased had this situation, and only 40% were still on sale. His manager found something wrong and suspended the sale of the remaining products. The hydraulic valve manufacturer believed that this was caused by the improper use of the hydraulic valve block by the user, and was only willing to replenish 10% of goods to solve this problem. His manager asked him to find a qualified hydraulic valve block supplier as soon as possible. Because the use scenario of this hydraulic valve block was special, Mason knew that AAK HYDRAULIC VALVE could solve this problem, but his did not have authority to pay a 7% higher price. He contacted no less than 10 hydraulic valve manufacturers, and only 3 of them replied. They could solve the paint falling and rust spots on the surface of the hydraulic valve block, but the internal pollution could not be 100% avoided because they did not know the user's operation. The remaining hydraulic valve manufacturers did not give any reply at all. Mason was very helpless. He had to bite the bullet and asked his manager for help if the purchasing price could be raised. When his manager learned about the whole purchase process, he asked Mason, why he did not report this situation in March? After the delivery date provided by AAK HYDRAULIC VALVE was agreed by his users, Mason sent us the order for this hydraulic valve block, and asked us to ship as early as possible. At the same time, his manager was curious about how we did it. The anti-rust treatment of AAK hydraulic valve block in the past is the same as that in other factories, which adopts surface painting or conventional electroplating treatment. The pain point of this process is that the hydraulic valve block is easy to be scratched, causing corrosion and increasing system pollution. We understand these potential problems of this process, and our technical team adheres to the new process exploration, so that AAK now has its own unique
9 months ago, we received an email from an old customer in the UK, informing that Berge had transferred from the quality control department to the import department. We could see from the email of the young man's self-introduction that he was full of confidence in procurement. Unfortunately, the first hydraulic valve order went wrong. A batch of orders for hydraulic flow valves shipped from a hydraulic valve manufacturer in Ningbo had no problem when tested before leaving the factory. However, when the goods were delivered to customers, the company received a series of quality complaints from consumers in only 1 month, and nearly 20% of the hydraulic flow valves had leakage. The manager was not very happy, and requested Berge to solve the guest's complaints within 1 week. Berge had discussed with the original hydraulic valve manufacturer several times, but it has not been effectively solved, and he even wanted to resign. Shawn, a former old purchaser, felt his frustration and reminded him to communicate with AAK HYDRAULIC VALVE to see if it could be solved. We received Berge's email with product drawings, pictures and test data of the defective hydraulic flow valves. We preliminarily judged that there was a problem with the valve spool. In order to solve the problem at one time, Berge asked his hydraulic valve manufacturer to send 5 samples of defective hydraulic flow valves to AAK HYDRAULIC VALVE for thorough inspection. After receiving the hydraulic flow valve samples, frankly speaking, the main line type of the hydraulic flow valve was acceptable. The problem was that the valve spool deviated from the central axis, resulting in leakage. Of the 5 hydraulic flow valve samples sent, two were in this situation, and the other three were of acceptable quality. This proved what we said before that it was difficult to 100% ensure that the valve spool did not deviate from the central axis due to human error, which was a hidden problem among peers. I suggested him to replenish 40% hydraulic flow valves to their customer within 30 days. If the customer could accept this suggestion, we would give priority to the production of these replenished hydraulic flow valves. A week later, Berge informed by email that his manager had agreed to the plan and his customer could accept only 20% replenishment. They just repeatedly stressed that the replenishment of the hydraulic flow valve could not have any quality problems. AAK realized a few years ago that the hydraulic flow valve produced by CNC lathe has high requirements for operators and is prone to human errors, resulting in the deviation of valve spool from the central axis. On the production equipment, AAK HYDRAULIC VALVE have imported the Swiss machine tool with the highest precision to make up for the short board of CNC lathe. At present, less than 10% of the peers have this equipment. It can replace 7 groups of accessories at random.
AAK HYDRAULIC VALVE Classified the Types of Hydraulic Cartridge Valves from the Perspective of Installation, and Berge Puts Down His Uneasy Heart The types of hydraulic cartridge valves can be classified from different angles. Sometimes, buyers who purchase hydraulic cartridge valves are confused. After all, they are not engineers. In order to classify more simply and intuitively, AAK HYDRAULIC VALVE describes the types of hydraulic cartridge valves from the most extensive installation point of view. In this way, we can divide the hydraulic cartridge valves into 3 types: Insert-type, Slide-in and Screw-in. Berge, an old British hydraulic valve customer, was transferred from the quality control department to the import department. He is a very studious buyer. Maybe it's fate, we often discuss some knowledge points about hydraulic valves. Some time ago, he didn't understand that every time, when the domestic hydraulic valve manufacturers receive an inquiry about his hydraulic cartridge valve, they always ask about the type of hydraulic cartridge valve. The question about the type of hydraulic cartridge valve made him very nervous and helpless. Indeed, there are many types of hydraulic cartridge valves now, from the perspective of function, hole type and scene. We found that they are most commonly classified from the perspective of installation, which is easy to understand and remember. I summarized our hydraulic cartridge valve types to Berge. After reading my following report about the types of the hydraulic cartridge valves, he told me that this classification for the hydraulic cartridge valve types can basically cover more than 80% of the hydraulic cartridge valves. Here, I'll also share with you the types of hydraulic cartridge valves I gave him. Common types of hydraulic cartridge valves are as follows: The Insert-type hydraulic cartridge valves: completely enters the inside of the valve block and does not expose any part outside the valve block. It is positioned by its own thread or other components such as pipe joint, snap ring, retaining ring etc. For example, hydraulic check valve and two-way hydraulic flow regulating valve have this design. The slide-in hydraulic cartridge valves: it does not have installation threads itself, and the valve spool needs to be used together with the cover plate. The valve spool is integrated in the valve block to switch the oil circuit on and off through pressure and spring force. Different cover plates are used to realize direction control, pressure control and flow control. Screw-in hydraulic cartridge valves, that is, hydraulic threaded cartridge valves, have different brands and different hole types, which are usually unable to be interchanged in installation. At present, there are 3 commonly used pass types: ISO7789, SAE and SUN.
Maarten purchased a batch of hydraulic valve blocks some time ago. In the early test, the system parameters were normal. Strangely, 10 days after the hydraulic valve block was started, the hydraulic oil in the system suddenly deteriorated. The technician immediately suspended the operation of the whole test system. After inspection, it was found that there were small iron filings in the hydraulic oil, and the valve spool of the cartridge valve connected with the hydraulic valve block also showed signs of wear. Maarten mentioned these problems to the hydraulic valve manufacturer, but the hydraulic manufacturer asked the customer to use better hydraulic oil and avoided the problem of his own hydraulic valve block. With delivery date approaching, Maarten is very helpless. Maarten really had no choice but to try to find other suitable hydraulic valve manufacturers on the website to take over the hydraulic valve block order. He consulted no less than 10 manufacturers in a week, but all manufacturers gave the same reply, they could not 100% avoid fine iron filings. This made Maarten start to doubt the ability of the hydraulic valve manufacturers in China. Before, Maarten had a certain understanding about us AAK hydraulic valve through some B2B websites, so with a try mentality, he directly emailed us a trial order for 5 hydraulic valve blocks. After receiving our hydraulic valve blocks, Maarten tested and compared, he found that AAK hydraulic valve block has strong sealing, high precision and gloss finish. What's more, he was glad that there was no iron filings residue. He immediately sent the drawings, quantity, delivery date and other detailed requirements of the hydraulic valve blocks currently being purchased from the other hydraulic valve manufacturer. After confirming all details with us, he cancelled the order with the original hydraulic valve manufacturer. At this moment, Maarten could finally rest assured. Why do more than 10 hydraulic valve manufacturers dare not accept the order of this hydraulic valve block? Because this hydraulic valve block is very special. There are many slender holes in the processing channels intersected by each hydraulic valve block, and the cleaning of iron filings is a cumbersome process. If there is no unique skill, it is difficult to eradicate it 100%. 2 years ago, AAK hydraulic valve also had an order cancelled by customer due to the iron filings of hydraulic valve block not completely eradicated. After that lesson, our technical team spent half a year innovating the production process of hydraulic valve block, and finally AAK hydraulic valve was able to mass produce the hydraulic valve without iron filings 1 year ago.
AAK hydraulic pressure valve has no horn hole. In Ningbo, the hydraulic valve production base, few factories are sure to solve the horn hole. AAK uses automatic programming software to program and upgrade the processing technology of hydraulic valve cavity hole. The geometric tolerance of each hole is within 0.02mm. At the same time, small fillet is used to replace the R angle of our peers to transition, which completely avoids the horn hole. Most hydraulic valve manufacturers use manual programming to design the geometric tolerance of cavity hole, which is prone to human error and can not be corrected. At the same time, due to the limitation of operation methods, the transition angle between small holes in the hydraulic pressure valve generally adopts the R angle for transition, which is easy to artificially leave a small space that is not easy to detect, so the horn hole will probably appear. After the hydraulic pressure valve is used for a period of time, the horn hole is easy to leak. What's more troublesome is that the oil stain outside the hydraulic pressure valve is easy to enter the valve spool and damage the whole hydraulic system. Adair, a hydraulic valve purchaser in Scotland, had many contacts with AAK hydraulic valve before, because he pursues low price, there is no cooperation between us. In July this year, he placed an order for hydraulic pressure valve worth 80,000 US dollars to a hydraulic valve manufacturer in Ningbo. 2 months later, the quality of the hydraulic pressure valve failed to meet the standard every time. Adair realized that even if it took another 2 months, the sample still could not be approved. Adair accidentally saw an article from AAK about "horn hole" on the B2B website, he further sourced until he got to the AAK website: www.aakindustry.com, he realized that it was the hydraulic valve manufacturer he had been contacting. When we received Adair's email, we understood the problems and causes of his hydraulic pressure valve. 3 days later, we received the hydraulic pressure valve samples that he asked the original hydraulic valve manufacturer to send, we found that the processing coaxiality of the cavity hole diameter of the combined holes of these hydraulic pressure valves was between 0.03-0.05mm, and there were tool connecting traces at the transition R angle. After we took the video and sent it to him, he understood why the samples of the original hydraulic valve manufacturer were always not approved. After receiving the video, Adair transferred the order of this hydraulic pressure valve to us AAK hydraulic valve the next day. At the same time, Adair also joked that you found the problem, but not means that you are able to solve the problem. How does you AAK hydraulic valve do and make me believe that you can 100% solve these hidden problems.
Kaden, a hydraulic valve purchaser from the United States, has been successfully purchasing hydraulic valves from China in recent years, and his boss also attaches great importance to him. Last month, at the original hydraulic valve manufacturer, he placed an order for a hydraulic valve block with multi-stage valve spool hole. The manufacturer confirmed that there was no problem and submitted the PPS of hydraulic valve block for 3 times, but the accuracy of valve spool hole was not approved every time. This made his customer very unhappy and thought it was a waste of his time. If the 4th hydraulic valve block sample still could not be approved, the order would have to be cancelled. The boss was also surprised and asked him to solve it within a time limit. Kaden felt unprecedented pressure. Kaden realized that the current hydraulic valve manufacturer must be replaced and contacted with no less than 10 hydraulic valve manufacturers. No factory has the ability to accept the order of this hydraulic valve block. Because the valve spool hole of this hydraulic valve block had a multi-stage structure, the accuracy was difficult to be controlled, the diameter tolerance of the valve spool hole of the hydraulic valve block was small, and there were many accuracy requirements such as coaxiality. Kaden was a little frustrated and seemed to have to give up. A hydraulic valve manufacturer in Ningbo told Kaden that the multi-stage valve spool hole must be processed with URMA reaming technology, and AAK hydraulic valve had this technology and could have a try. Kaden contacted us AAK hydraulic valve, directly indicating that he was introduced to us by a hydraulic valve factory, now he was in trouble with a special hydraulic valve block. He sent us the drawings and parameter requirements of the hydraulic valve block, and asked whether we were sure to be able to produce this hydraulic valve block. After analyzing the drawings, the technical team of AAK hydraulic valve told him that we would send the samples of hydraulic valve block directly to him for testing after 12 days. If the accuracy of hydraulic valve block met the requirements, we could produce it. Kaden requested that the PPS of the hydraulic valve block must be good so as not to completely disappoint his customer. On the 5th day after receiving the sample, he was very happy to inform us by email that after two tests by his company and his customer, AAK's hydraulic valve block met the requirements. He asked us to prepare materials and production can be started once other details are determined. AAK hydraulic valve URMA reaming technology adopts guide bar support to ensure correct tool position and rigorous cooling to ensure tool lubrication. Especially for multi-stage valve spool hole, or valve spool hole with small diameter, we have our own processing experience. This is rare in Ningbo hydraulic valve manufacturers.
AAK pilot hydraulic pressure valve adds welded high-strength filter screen at the inlet section of slender hole, and the damping hole is 100% unblocked. Colin faced 4 times of hydraulic pressure valve approval failures, which were solved at one time by AAK hydraulic valve. Many hydraulic valve manufacturers believe that the pilot hydraulic pressure valve has fine impurities and is easy to block the pilot stage slender hole, which is determined by the special structure of the hydraulic valve. Therefore, they just remind customers to use high-purity hydraulic oil and never reflect on their production process, resulting in many hydraulic valve customers falling over here. Colin is the purchasing supervisor of a hydraulic valve company in Germany. He has a batch of orders for pilot hydraulic pressure valves recently. During sample approval stage, it was found that some fine impurities could easily block the pilot stage slender hole, resulting in the blockage of the damping hole, the loss of pressure of the pilot stage and the failure of the pressure valve. The hydraulic pressure valve sample was modified for 4 times, but it was still unapproved. Colin looked for no less than 20 hydraulic valve manufacturers within 7 days, and only got a reply from 3 hydraulic valve manufacturers: they could not make sure that the damping hole was 100% unblocked. The remaining more than 20 hydraulic valve manufacturers did not give any reply at all. Colin happened to see an article about damping hole blockage of AAK hydraulic valve on B2B website. With a try attitude, he contacted us AAK hydraulic valve and asked about the treatment of damping hole blockage. After we asked him about the parameter requirements and use scenarios of his hydraulic pressure valve, we said there was no problem and could rest assured to proofing. Colin didn't think too much either. He tried again with the mentality of making every possible effort. Unexpectedly, the pilot hydraulic pressure valve sample made by AAK not only passed the testing but also solved the problem of damping hole blockage, and the pressure debugging was more sensitive and stable. The next day, he transferred the hydraulic pressure valve order to AAK. He wondered why hydraulic pressure valve of AAK proofing passed testing at one time. In order to deal with severe working conditions more effectively, AAK hydraulic valve reduces the impact of oil pollution on the pressure valve, and has optimized and upgraded the pilot hydraulic pressure valve process for a long time. While improving the oil inlet stability, the welded integral high-strength filter screen and local turbulent self-cleaning function are added to the inlet section of the pilot slender hole, so as to reduce the impact of oil pollution on the normal operation of the hydraulic valve. The opening and overflow characteristics of the hydraulic pressure valve are better, and the pressure curve is less affected by the change of overflow flow
AAK adopts the high-pressure solution injection method, weakens the magnetism of the burr with the solution, and then uses the instantaneous impact force of the liquid to not only ensure that the burr of the hydraulic valve block is 100% eradicated, but also effectively clean each part of the hydraulic valve block. Most of its peers do not have such a process. After learning about it, the American customer sent an inquiry sheet for the hydraulic valve block worth US$20,000 within 20 minutes. Throughout the entire hydraulic valve industry, the deburring of hydraulic valve block is still manual. The work piece is polished with tools such as file, sandpaper and grinding head. This method has blind spots, general effect and low efficiency, especially for the burrs in complex cross holes. Even the later inspection can not find the burr hidden in the hydraulic valve block. Eric, an American hydraulic valve customer, purchased a batch of hydraulic valve blocks from a hydraulic valve manufacturer some time ago. Problems were found in the test stage. The pressure regulation of the hydraulic system was unbalanced. After careful analysis, it was found that there were different degrees of burrs at the cross holes of the hydraulic valve blocks. After modifying the hydraulic valve block sample several times, the burr could not be 100% eradicated. His client did not accept the quality of the hydraulic valve block, and Eric could only reconsider other manufacturers. Eric saw an article on deburring treatment of hydraulic valve block of AAK hydraulic valve on B2B website and found that it was similar to his current problems. Eric sent us his hydraulic valve block drawing and the problems encountered by email. He asked us how to deal with the burr problem of hydraulic valve block? The burr shape and size of the hydraulic valve block are related to the spindle speed, drilling feed, work piece material, cutting tool, coolant, bit geometric angle and other factors. It really needs unique skills to clean it thoroughly. AAK hydraulic valve mainly adopts the high-pressure solution injection method, uses the solution to weaken the magnetism of the burr, and then uses the instantaneous impact force of the liquid to not only ensure that the burr of the hydraulic valve block is 100% eradicated, but also effectively clean each part of the hydraulic valve block, with high efficiency and no dead corner. Within 20 minutes after Eric received our email reply, he sent an inquiry for the hydraulic valve block worth US$20,000. According to his hydraulic valve block drawings and parameter requirements, we calculated the most advantageous hydraulic valve block price. For a week, we didn't hear any news from Eric. We thought he wouldn't order the hydraulic valve block. But we didn't expect that after 15 days, we received his order for the hydraulic valve block. Purchase burr free hydraulic valve block, choose AAK hydraulic valve, you can have a try.
