Chaika is from Pakistan, and has cooperated with AAK for hydraulic cartridge valves for more than 3 years. His boss trusts him very much. At the beginning of last year, a number of their hydraulic paper cutters were complained by customers. The problem was that the hydraulic directional cartridge valve spool was worn and stuck. His boss was surprised. In the purchasing from AAK for more than 3 years, there was no quality complaint about the hydraulic directional cartridge valves. After checking, it was learned that this hydraulic directional cartridge valve is a standard part of HydraForce. Chaika found a manufacturer that is 20% cheaper than AAK to place the order. The boss asked Chaika to re-purchase the hydraulic directional cartridge valves from AAK for replacement. Chaika candidly told us the problems encountered on this hydraulic directional cartridge valve, and needed the help of AAK, to urgently produce 50 hydraulic directional cartridge valves within 30 days. After 25 days, AAK successfully delivered the hydraulic directional cartridge valves. 4 weeks later, Chaika informed that the problem of the equipment being complained about had been solved. This time, the boss was not happy and the customer was not satisfied, which made him under great pressure. He thanked me for solving the problem of the hydraulic directional cartridge valve in time. I told him that although AAK hydraulic directional cartridge valve is 20% more expensive, its service life is twice that of its peers, it has stable manufacturing quality, durable and fault-free, due to the following 3 efforts: 1. In terms of material, AAK hydraulic directional cartridge valve, the spool is made of 100Cr2 bearing steel, and then targeted heat treatment. Permeating at 820-830 ° high temperature for 13 hours, then oil quenching, - 60 ° to - 70 ° cryogenic treatment,+150 ° to+160 ° tempering treatment. Not only is the molecular structure uniform, but also the hardness is increased to HRC68. The valve spool with good wear resistance and high strength, ensures that the service life of AAK hydraulic directional cartridge valve is twice that of its peers. 2. In terms of processing, the processing accuracy of AAK hydraulic directional cartridge valve can reach 0.01~0.3μm by Japan OKK ultra-precision machine tool. And the production efficiency is more than 30% faster. Under the operation of our old technician for more than 30 years of experience, the components processed have no defects. 3. In terms of detection, the German Diatest small micro-pore diameter measuring instrument is used to check and accurately measure the valve hole of AAK hydraulic direction cartridge valve, and the measurement can reach 0.1μm. AAK hydraulic directional cartridge valve, although more expensive by 20%, it has a service life of 2 times that of other cartridge valve manufacturers in China.

Mayer has been working in a hydraulic equipment company in Brazil for 3 years. In the first half of this year, they customized a hydraulic power unit for a customer. The pressure supply range is 20bar to 450bar. 3 direct-acting cartridge relief valves, high, medium and low pressure, are used. The equipment was debugged smoothly, and the customer was also very satisfied. However, the batch order was stuck because of the price. The customer reported that the price of similar equipment in the market was 20% cheaper than theirs, and requested that the price of this hydraulic power unit be reduced by 15% before the batch order could be confirmed. The boss asked the engineer to optimize the system to reduce cost. The engineer said that the only way to reduce the cost was to combine the 3 cartridge direct-acting relief valves into 1. The original cartridge relief valve manufacturer was powerless. Mayer contacted more than 10 cartridge valve manufacturers. They were either not interested or unable to optimize. 2 weeks later, no results were achieved. Mayer was worried. Mayer browsed AAK hydraulic valve in Google and left a message: 1. Can you customize the cartridge direct-acting relief valve with the applicable pressure range of 20bar to 450bar? 2. The original system uses 3 high, medium and low pressure cartridge relief valves. Can they be combined into 1 without affecting the function? 3. What is the lead time and cost for sample development? According to his message, I judged that either the cost was challenged or the customer was dissatisfied with the system. After communication, I learned the trouble he faced. Based on his production drawings of cartridge direct-acting relief valve and the system principle of the equipment, AAK engineers had a discussion and came out a plan, but only 90% is sure. Mayer may be hesitating and did not give us any news for a week. I thought he chose another cartridge relief valve manufacturer, but I suddenly received his trial order. After 50 days, 10 samples of AAK newly designed cartridge direct-acting relief valves were sent out. 1 month later, Mayer sent us a PO for 360 cartridge direct-acting relief valves, and mentioned that AAK newly designed direct-acting cartridge relief valves were used in equipment, and did not affect its functions, and helped them reduce the cost by more than 15%. Only then did customer place order for bulk equipment. According to the 3 levels of pressure, AAK has changed the structure of the original hydraulic direct-acting cartridge relief valve, reducing the manufacturing cost by more than 40%, in the following way: 1.A spring is arranged between the poppet valve spool and the pressure regulating screw plug, and the vertical position at the front end of the poppet valve spool corresponds to a cylindrical oil chamber, which is connected with the oil inlet hole. 2.The horizontal position at the front end of the poppet valve spool corresponds to the oil return hole. At the same time, a thrust belt is arranged around the front end of the poppet valve spool, and the poppet valve spool is provided with an oil hole. 3.The pressure oil enters the cylindrical oil chamber from the oil inlet hole, and the oil pressure acts on the thrust ring. When the generated thrust is less than the spring pressure, the poppet valve spool is closed; when its thrust is greater than the spring pressure, the poppet valve spool opens the overflow, which is suitable for the generalization of high, medium and low pressure overflow. Mayer told me privately that he was promoted to the position of purchasing manager a few days ago, and he was more and more energetic. AAK hydraulic direct-acting cartridge relief valve is applicable to all kinds of pressures. You can also have a small try! https://www.aakindustry.com/info-detai , l/cartridge-relief-valves-aak418

Nowadays, there are involutions everywhere in China, and so do the hydraulic cartridge valve manufacturers. The reason why you feel serious involution is because you are taking money from someone else's pocket. If you don't want to be in involution, go pick up the money on the ground. In the era of increment, the land is full of gold. Various hydraulic cartridge valve manufacturers are desperately picking it up. At this point, if someone steps on you, will you hit him? Not available. Don't stop me from picking up gold. In the era of stock, there was almost no gold on the ground. At this point, if a hydraulic cartridge valve manufacturer steps on you, will you hit him? Not only did you kill him, but also snatched the gold from his pocket. Hydraulic cartridge valve manufacturers feel that competition is becoming increasingly fierce, it is becoming increasingly difficult to make money, and they feel that they must do their best to live the life of ordinary people. So what should we do? The most direct way is to snatch money from someone else's pocket. This is also what every hydraulic cartridge valve manufacturer is doing today. For example, if a customer wants to purchase a hydraulic cartridge valve, there are 3 hydraulic cartridge valve manufacturers in front of the customer: A, B, and C. If you choose A, you cannot choose B or C. The same goes for choosing B and C. So, are you going to choose A, B, or C? Many hydraulic cartridge valve manufacturers have racked their brains for this issue - competing for price, service, and quality. What exactly is' snatching money from someone else's pocket? That is, strive for excellence without changing the original model. This pursuit of excellence must have eliminated many manufacturers of hydraulic cartridge valves. But in fact, each of us is enjoying the result of this' money grabbing '. Recently, SUN launched a new type of hydraulic cartridge valve, priced at $269/pc on its official website, which is high. However, it cannot be denied that the manufacturering of this hydraulic cartridge valve is demonstrating excellence. Where is the essence? The valve cage is made of high-strength alloy steel, and the valve spool is made of wear-resistant customized bearing steel. The sealing adopts PU polyurethane rubber sealing rings and a dual mode with PTFE retaining rings. The appearance is made of galvanized nickel alloy. Regardless of processing accuracy, product functionality and performance, take it to the new level. This valve will become the blueprint for different hydraulic cartridge valve manufacturers. As long as we follow the "formula" above to design, the performance will probably not be poor. All hydraulic cartridge valve manufacturers follow this formula and work tirelessly. The result of doing so is a price reduction, and SUN cannot escape the entire cycle. As a user, of course, we hope that the hydraulic cartridge valve manufacturers can be in involution. This way, you can buy better hydraulic cartridge valves at a lower price and enjoy better service. But as a manufacturer of hydraulic cartridge valves, I only think it's too involuted! The involution brings results, which we want. The involution brings competition, and we don't want it anymore. So, hydraulic cartridge valve manufacturers repeatedly struggled between participating and not participating. We put a lot of effort into how to steal money from others' pockets. Of course, it has also created some small actions under the table and distorted thoughts from hydraulic cartridge valve manufacturers. Can we demand both lower prices and better products and services, while also avoiding such competition? Of course there are. That's to go pick up the money on the ground. So how do we pick up the money on the ground? It is a thing that very few people are doing today. Can AAK do it? We are thinking and on the way. With the eye of insight, see users, see needs, see waste, and see value, instead of just staring at the little money in someone else's pocket. Let's make for it together.

Last October, our old Russian customer Matben sent me a video with the following message: take a look at the leakage of the hydraulic sequence valve in the equipment. Is there any way to solve the leakage problem? I was startled when I first read the email, thinking that there was a leak in the hydraulic sequence valve we previously shipped. I opened the video and took a closer look to find that there is a leak at the adjusting screw of the hydraulic sequence valve. The leakage at this point is a common problem for most hydraulic sequence valves and a challenge for most hydraulic sequence valve manufacturers. However, AAK has a clever solution to solve this small detail to avoid any leakage. After communication, it was learned that it was not the AAK hydraulic sequence valve that was leaking, nor was it their company's equipment that malfunctioned, but rather his friend Arata's equipment that was malfunctioning. Arata's hydraulic sequence valve was purchased from a hydraulic cartridge valve manufacturer in Ningbo and used in their mining equipment. After 6 months, the customer complained that the equipment would shut down. The root cause was a leak at the adjusting screw of the hydraulic sequence valve. The original manufacturer of the hydraulic sequence valve replied that the hydraulic sequence valve can only be used continuously in mining equipment, ensuring a service life of 6 months. The only solution to complaints is to replace the hydraulic sequence valve once every 6 months. Arata knows that neither his boss nor his client will accept such a costly and time-consuming after-sales service. Arata spent a week on sourcing but did not find a reliable manufacturer of hydraulic sequence valves, so he asked help from Matben, and I had the opportunity to see this video of hydraulic sequence valve leakage. I told Arata that the hydraulic sequence valves AAK supplied to Matben can work continuously for 10 hours a day and have a service life of over 1 year. This can be verified with Matben. Arata told me that this is the reason why he came to AAK and also the reason why Matt recommended AAK to him. After 40 days, AAK sent 20 samples of hydraulic sequence valves. 3 months later, Arata informed us that after internal testing, the service life of AAK hydraulic sequence valve exceeded 1 year without problem. He asked me to prepare the materials asap. They will place the regular order for this hydraulic sequence valve in a few days. AAK has a solution to the leakage at the adjusting screw of the hydraulic sequence valve, to address this small detail: 1.AAK hydraulic sequence valve O-ring, select the matching sealing ring from the aspects of structure, material fatigue resistance, medium, and aging cycle. 2.The screws used in the AAK hydraulic sequence valve have a performance level of 12.9, which is higher than the industry standard and has higher pressure resistance and is not easy to loosen. The service life has been increased by 30%. 3.AAK hydraulic sequence valve, 100% full inspection, controlling leakage from the source. AAK hydraulic sequence valve, small details, small tricks, works well, you can also give it a try!

The guard told me on Monday that there was an international parcel in the office. From the shipment airway bill, it was a sample of hydraulic valve block from an old American customer Zero. I was a little puzzled. Zero only purchases hydraulic cartridge valves from AAK. I didn't know why he sent me the hydraulic valve block sample until I read all the emails today. Zero introduced in the email that he purchased this hydraulic valve block from a friend, the quantity was not big, just 100 pieces. The hydraulic valve block was easy to leak after being used for a period of time. He didn't know the source of the leak and asked me to help have a check. After the pressure test and inspection, our technician analyzed that the leakage was serious and the pressure could not reach the pressure value of the system. I told Zero that the original manufacturer of this hydraulic valve block judged that the hydraulic valve block was qualified without strictly controlling the data in the pressure test stage. For this kind of hydraulic valve block, AAK did this in the pressure test stage, and this method has been used since 5 years ago. After the production of the hydraulic valve block is completed, start the pressure test. First, adjust the throttle valve opening on the hydraulic valve block to the maximum, and at the same time, adjust the pressure valve adjusting spring to a very loose state, and then gradually increase the pressure. When the pressure reaches the required test pressure, our pressure holding time is 10min, while the pressure holding time of most hydraulic valve block manufacturers is 3min. The problem is easy to be exposed if the pressure is maintained for a long time. If there is leakage during the pressure maintenance, the source can be traced, and special treatment of sealing glue can be added at the joint surface. At the same time, after the test is completed, adjust the relief valve on the hydraulic valve block to the set pressure value required by the system to achieve the internal pressure balance of the valve block system. Few manufacturers do this step. Zero realized that only AAK could ensure that there was no leakage in the hydraulic valve block, so he asked me to arrange 100 hydraulic valve blocks on the production line in a hurry. The pressure maintaining test is the key to check the leakage, but to produce a leak-free hydraulic valve block, AAK do these in production: first, select the appropriate processing material according to the working conditions of the customer's hydraulic valve block, and ensure that the internal organization of the processed valve block material is dense, without foreign objects, sand holes and other defects. If necessary, flaw detection will be carried out on the blank material. Secondly, the control of machining precision is also very strict, and the machining of all threaded holes on the valve block is guaranteed to be above 7H; In addition, the perpendicularity tolerance between the screw hole of the installation pipe joint and its external mating surface shall be at least Class 8. For picky hydraulic valve blocks, production is the core and detection is the key. AAK strictly controls these 2 processes to ensure that the hydraulic valve block has no leakage. There are not many manufacturers who can achieve these 2 details. It is not that they don't want to do it, but that they don't have enough ability to control the details. AAK hydraulic valve block, no leakage, welcome to try! https://www.aakindustry.com/info-detai , l/hydraulic-valve-blocks-aak291

Last week, once a hydraulic manifold drawing was approved, the customer wired the full payment of more than US$50,000 US dollars at one time, and the delivery was 2 months later. This is a customized hydraulic manifold. It is the first order from an Italian customer. It is the first time for him to cooperate with AAK Hydraulic Valves. I think behind his action is his trust in AAK Hydraulic Valves. If we say what is the most important asset in the future, I think it is "trust". If what is the most terrible risk in the future, I think it is "lack of trust". Some customers agree with the manufacturing quality of AAK Hydraulic Valves, know that AAK is the supplier of the first brand of hydraulic valves (HydraForce) for 9 consecutive years, and know that although AAK Hydraulic Valves are 20% more expensive than their peers, its service life is twice that of their peers, but they don't place orders. Why?   There are only 2 reasons: first, he is not a customer of AAK. Second, customers do not trust AAK enough, or AAK does not deliver enough trust. So trust is very important for the first order customers. Is it your customer? This is a very interesting topic. One third of the customers and you are predestined, trust each other, and work with him at the same frequency, and feel not tired; One third of the customers have no fate with you. No matter what you do, there will be no reply after you quoted the price; One third of the customers need to be won over and moved. This is what I think and do in regards of trust. First of all, learn to trust others, but also learn to be trusted. Those who can trust others are lucky mountains. You dare to trust others, which proves that you need the help of the other party, and it also proves that you are willing to give your back to the other party, not afraid of being stabbed by him. Then, expose yourself in exchange for more cooperation. If you always guard against others, there is no possibility of cooperation. Trust others and give my back to them. If you rely on others, others also rely on you. And the person who can be trusted is a powerful sea. Yes, the customer of AAK Hydraulic Valves is lucky mountain, and AAK is the strong sea of customers. Finally, it is the transmission of trust. If others want to cooperate with you as soon as they see you, because you can help others. If I help more people, it will be my motivation and responsibility. For AAK Hydraulic Valves, the customer is mountain, we are the sea. https://www.aakindustry.com/info-detai , l/hydraulic-manifolds-aak290

Last Wednesday, there was a repeat order from Peppe for a hydraulic valve block, which was tested in the second half of last year. Peppe required that the repeat order quality should be 100% burr free as same as the hydraulic valve block tested samples last year. Peppe comes from a hydraulic equipment company in Italy. At the beginning of last year, the paper cutter equipment they sold would stop automatically and was complained by customers. It was found that the hydraulic relief valve was stuck on the site, and the after- sales servicer thought that there was a problem with the hydraulic relief valve. After the original hydraulic valve block manufacturer disassembled it, it was found that there were debris at the moving part of the valve spool. At the same time, foreign matters were also found in the hydraulic oil, so it was known that it was caused by the incomplete burr cleaning of the hydraulic valve block. The original hydraulic valve block manufacturer also does not deny it. The burr cleaning of the inner cavity of the oil channel, the cross hole and the blind hole of this hydraulic valve block was indeed less than 100%. As long as the hydraulic oil can be replaced every 3 months, the problem can be solved. Peppe was very speechless and had to find a new hydraulic valve block manufacturer, and deliberately required 100% burr free. She contacted more than 10 hydraulic valve block manufacturers, they either gave no reply or could only have a try, but Peppe didn't have time to test, and began to worry. Peppe noticed the introduction of "100% burr free hydraulic valve block" in AAK on Google, so she directly sent us an email. I told her, "according to your hydraulic valve block drawing, there are many inner cavities and cross holes in the oil duct, especially the burr cleaning at the blind hole is a difficult problem. The traditional abrasive flow deburring method to remove this hydraulic valve block has hidden dangers. AAK suffered from it 5 years ago, and it was not until we used the new deburring technology that we dared to ensure 100% burr free". Peppe asked us to make samples as soon as possible. A month later, AAK sent 5 hydraulic valve blocks. 6 months later, Peppe emailed us that the paper cutter installed with AAK hydraulic valve block has been working normally. I told her that AAK adopted an intelligent grinding processing system to replace the traditional abrasive flow process. If this hydraulic valve block is deburred with abrasive flow, and the blind hole is easy to form a dead corner. The intelligent grinding and processing system can realize automatic solution. In the grinding process of the hydraulic valve block, with continuous power support and stability, the main shaft of the equipment can swing 360 °, which can realize the grinding of any angle and any inclined plane. No matter in the fixture positioning, or in the automatic optimization compensation of the simulation path simulation of the hydraulic valve block structure, the intelligent grinding processing system has no dead corner. No matter the surface of the hydraulic valve body, or the inner hole, cross hole, blind hole of the hydraulic valve block, as well as the end face and inner and outer contour of the orifice, the burrs can be completely removed. AAK hydraulic valve block, no burr, you can also have a small try! https://www.aakindustry.com/info-detai , l/hydraulic-valve-block-aak289

Andrea is from a British hydraulic equipment company. At the beginning of last year, they received an inquiry for hydraulic cylinders used in national defense military equipment, which needed to use hydraulic check valves. The specific requirements for the hydraulic check valve are: internal leakage 2drop/min, surface roughness Ra 0.1-0.2μm, concentricity tolerance of valve spool and valve hole is 0.005-0.01mm. These 3 requirements are more than twice as high as the standard parts of hydraulic check valves. Andrea realized the difficulty of purchasing, and contacted more than 10 hydraulic check valve manufacturers online and offline. Except for an old supplier who had cooperated for several years told her that he was 90% confident to meet the requirements, all other manufacturers could not achieve these 3 requirements. After 45 days, the hydraulic check valve sample was installed on the oil cylinder, and less than 12 hours after commissioning, the hydraulic cylinder was running unstably during reciprocating motion. During disassembly, the engineer found that the hydraulic check valve had internal leakage, which exceeded 2 drops/min, and the concentricity tolerance also exceeded 0.01mm during testing. Andrea was helpless and had to continue to look for new hydraulic check valve manufacturers. More than 1 week had passed, the manufacturer had still not been confirmed yet. Andrea was urged by her boss and got anxious. Andrea browsed AAK website in Google and felt that AAK could help her. She sent an email to ask about it, and we learned about the purchasing difficulties she encountered. According to the hydraulic check valve drawing and the schematic diagram of the whole hydraulic system provided by her, there are few hydraulic valve manufacturers who can meet the accuracy requirements of this hydraulic check valve. After discussion, our technical team replied to Andrea the next day that AAK was able to develop this hydraulic check valve. The development cost of this hydraulic check valve was at least US$2,000. 2 days later, Andrea directly placed a trial order and paid the development fee. 45 days later, AAK sent 30 samples of hydraulic check valves. 1 month later, Andrea told us that the test run was successful, and the boss was very satisfied that she found AAK, The success of AAK ultra-high precision hydraulic check valve lies on the following 3 points, which is also why Andrea only found AAK to try this hydraulic check valve. 1. AAK uses a precision honing machine imported from the United States. After honing, the accuracy of the hydraulic check valve hole is IT7 ~ 4, and the surface roughness Ra value can reach 0.1-0.2μm, so as to ensure that the internal leakage reaches the requirement of 2 drops/min. 2. After processing, use the Mahr cylindricity meter imported from Germany to accurately measure each part of the hydraulic check valve through EasyForm software to ensure that the concentricity tolerance of each hydraulic check valve spool and valve hole is less than 0.005mm. 3. AAK ultra-high precision hydraulic valve was used by a Russian customer in the aviation field in 2019. That is already a fact, so the military industry is not a problem, too. AAK hydraulic check valve can be used in military industry. You can also have a try! https://www.aakindustry.com/info-d , etail/hydraulic-check-valve-aak288

A few days ago, someone left a message about a tweet that hydraulic cartridge valve manufacturer AAK posted on a B2B website: Do hydraulic cartridge valve manufacturers also need to promote? At most, advertise on Google. He meant that hydraulic cartridge valve manufacturers only need to advertise. I'm not sure whether he is a hydraulic cartridge valve manufacturer or a hydraulic cartridge valve customer, but his IP is from Türkiye. Whether it is a hydraulic cartridge valve manufacturer or an individual, in this online age, it seems that they cannot do without the 5 modules of sales promotion, advertising, public relations, planning, and brand. How can these key words be connected? I think of my previous experiences in bars, various chat ups in bars, and the promotion of hydraulic cartridge valve manufacturers, which are quite similar. You go to the bar and sit down. Not long after you walked in, a girl directly approached you and said that you are tall, wealthy, and handsome. This is called sales promotion. When you get excited, you want everyone in the bar to know that you are tall, wealthy, and handsome, and then spend money to have the DJ notify everyone in the bar that you are tall, wealthy, and handsome, which is called advertising. Since the advertisement has been launched, if you want to see the effectiveness of the advertisement, ask the bar owner to arrange a private seat and chat with the girl alone, saying that you are a wealthy and handsome person who is very reliable, which is called public relations. You ordered the most expensive red wine in order to further build your high wealth and handsome appearance. The bar arranged for 10 people to queue up and deliver it to you, attracting bar girls. This is called event planning. The girl knows that you are a tall, wealthy, and handsome person, and takes the initiative to approach you. This is called brand attractiveness, or the girl has developed a sense of trust in you. The hydraulic cartridge valve manufacturer AAK in China promotes its daily content with a slow heart and diligent hands, leaving AAK's footprint everywhere on the internet. Use our manufacturing quality and service to differentiate it from the hydraulic cartridge valve manufacturer peers, and use AAK's advantages, characteristics, and professionalism to build trust in the online space. Chairman Mao said that doing a good deed is not difficult, but what is difficult is doing a good deed for a lifetime. AAK said that it is not difficult to promote once, but it is difficult to promote every day. If I am fragrant, butterflies come naturally, and I insist on manufacturing quality, and benchmark against international top brands. With our advantages, characteristics, and quality, we differentiate ourselves from other hydraulic cartridge valve manufacturers in China. Only in this way can the road be smooth. Although it may be a bit difficult, difficult roads are never crowded and eventually arrive.

For a hydraulic cartridge flow control valve, with many internal oil passage holes in different apertures and 60 ° seating holes, and the accuracy requirement below 0.8μm, Hemendra asked the most trusted local cartridge valve manufacturer to make samples. 3 weeks later, the manufacturer found that the scrap rate of the hydraulic flow control cartridge valve was more than 60%, and the efficiency was low, so he gave up. The other hydraulic cartridge flow control vale manufacturers had little interest in making samples. After AAK took over, it adopted a five-stage forming reamer from Germany, and the cutter has several blades with different diameters. This tool, solves the processing of all oil passage holes, and the hole accuracy is within 0.5μm, 40% higher than the original requirement. AAK hydraulic cartridge flow control valve enables Hemendra to receive the order for hydraulic cylinders successfully. Hemendra is from India, and has purchased hydraulic cartridge valves from AAK for 5 years. Some time ago, one of their hydraulic cylinders needed a customized hydraulic cartridge flow control valve, but encountered difficulties. He contacted me. After communication, I learned the difficulties he encountered in local hydraulic cartridge valve manufacturers. Because of the wasted time in the early stage, he needs AAK to send the hydraulic cartridge flow control valve sample within 40 days. According to his drawing, it is difficult to process the valve hole, but AAK has experience in this aspect. After 35 days, AAK sent 20 samples of hydraulic cartridge control valves. During CNY, Hemendra told me that the customer was satisfied with their hydraulic cylinder prototype and would like to place the annual order. He asked me to give priority to his orders for the hydraulic cartridge flow control valves. Hemendra also specially thanked me. The sample of AAK hydraulic flow control cartridge valve is not only delivered fast, but also stable in manufacturing quality, especially the valve hole accuracy reaches 0.5μm, which is 40% higher than the original requirement. AAK hydraulic flow control cartridge valve, in the finishing process, uses five-stage forming reamer, which is from Germany, and has multiple blades with different diameters. A tool, solves the processing of all oil passage holes, and the hole accuracy is within 0.5 μm, which is 40% higher than the original requirement. The reamer has a plurality of cutter teeth, and the reamer body is provided with a cutter bar, a cutter handle and a cutter. The reamer body is connected with the machine tool through the tool handle. The five-stage forming reamer can easily shape the 60-degree seat face. It is tapered and can be positioned. Especially, the tool has multiple blades with different diameters. Under the operation of our skilled workers for more than 30 years, the processing efficiency is high and the accuracy is guaranteed. AAK hydraulic flow control cartridge valve, is processed with good tool, by good craftsman, with high precision, you can also try it. https://www.aakindustry.com/info-detail , /flow-control-cartridge-valves-aak487

Phoebe comes from Greece, and has been purchasing hydraulic valves from Ningbo for 2 years. At the end of last year, their hydraulic power unit required a hydraulic pressure control valve, and Phoebe tested the sample from a cartridge valve manufacturer that had been cooperating for 2 years. During debugging, the equipment was unstable in operation, and it was found on site that it was rooted in the internal cone angle error of the hydraulic pressure control valve and the excessive axial grinding tolerance of the sealing circle. The original hydraulic pressure control valve manufacturer re-made samples two times, but the machining accuracy of the hydraulic pressure control valve still did not meet the standard. Phoebe realized that she needed to change the manufacturer of the hydraulic pressure control valve. After trying with another hydraulic pressure control valve manufacturer, the problem was not completely resolved for a month, and the boss was very angry that Phoebe was in a hurry and became anxious. In early March, Phoebe approached me through an introduction from peers in Ningbo. The first sentence of her email was: Can you ensure that each hydraulic pressure control valve is 100% leak free? For similar messages, AAK always gives reply as soon as possible, as the other party must have encountered difficulties in purchasing hydraulic pressure control valves. After communication, it was learned that the accuracy of the hydraulic pressure control valves produced by both previous manufacturers did not meet the standards. The root cause of the problem has been identified. Ensuring the hydraulic pressure control valve is 100% leak free is not difficult for AAK. AAK can make samples, and if the samples do not meet the standards, all fees can be refunded. After 35 days, AAK sent 10 samples of hydraulic pressure control valves. Today, Phoebe sent a PO for 300 hydraulic pressure control valves. Excitedly, the equipment has been running stably, and their engineer is satisfied with the machining accuracy of AAK hydraulic pressure control valve. The boss also praised her. AAK processed it in this way. AAK uses the TSUGAMI CNC precision automatic lathe imported from Japan, which can control the machining accuracy of each valve cage within 2 μm. At the same time, during the production process, the application of detection devices can capture test data at any time, and the machining accuracy of each inner cone surface is visible, ensuring that the error control range of the inner cone angle is ± 0.8 °, and the axial grinding tolerance of the sealing circle is 0.075 μm. This is a specialized three coordinate measuring instrument detection device designed by AAK based on the structural characteristics of the valve cage. This is not only a trick, but also a 100% leak free skill. Most of the hydraulic cartridge valve manufacturers in Ningbo can only imagine, but may not be able to do it. AAK hydraulic pressure control valve, with precision tips, no leakage, you can also give it a try!

Nancy comes from a hydraulic equipment company in the United States. In October last year, they developed a hydraulic power unit that used a hydraulic counterbalance valve. Nancy purchased the standard parts of SUN hydraulics counterbalance valve according to the model required by the engineer. During the commissioning of the hydraulic power unit, the oil cylinder shook and made abnormal noise shortly after the equipment was started. After checking the design principle and installation method, the engineer judged that the problem probably lied in the hydraulic counterbalance valve. They asked to replace it with a new hydraulic counterbalance valve, but SUN after-sales personnel said that there would be no problem with the SUN hydraulic counterbalance valve and were unwilling to replace it. The engineer tested the hydraulic counterbalance valve separately, and the parameters were also normal. The technical team was confused. The promotion date of the new equipment was coming, but the machine test was stuck now, and the boss was also very anxious. Nancy tried to consult with different hydraulic counterbalance valve manufacturers, but after a week, there was no progress. She found AAK on Google and left a message to us: After using SUN hydraulic counterbalance valve, the equipment commissioning was abnormal, but no abnormality was found in the separate test of hydraulic counterbalance valve. At first glance, there seems to be no solution. Our engineer suggested Nancy to provide working condition requirements, hydraulic schematic diagram and equipment abnormal video. After discussion, AAK technical team judged that there was a problem with the flow selection of the hydraulic counterbalance valve. I told her that the flow difference of the cylinder diameter ratio of their power unit was 2.3 : 1. Although this ratio could be used for the standard parts of SUN hydraulic counterbalance valve, its stability was difficult to be guaranteed. This was the reason why the oil cylinder vibrated and made abnormal noise during the test run. Their engineers also recognized the reasoning of AAK technical team and asked AAK to customize standard two-way hydraulic counterbalance valves with appropriate flow. 45 days later, AAK sent 20 hydraulic counterbalance valves for test order. 2 weeks later, Nancy informed by email that the test run was successful with AAK hydraulic counterbalance valves, and the oil cylinder jitter and abnormal noise were disappeared, which could also catch up with the promotion of the equipment. Purchased a hydraulic counterbalance valve with unsuitable flow, no one in the company could solve the problem. It was solved by using AAK non-standard customized hydraulic counterbalance valves. Our engineers redesigned the hydraulic counterbalance valve, converted the appropriate flow according to the cylinder diameter ratio, adopted small cavity and small flow, and added bypass damping at the control port of the hydraulic counterbalance valve to improve the control stability of the valve, which can also completely solve the shaking and abnormal noise of the oil cylinder. Nancy privately told me that the boss was very satisfied with her behavior. The problem that should have been solved by the technician was solved by the purchaser. The boss not only praised her in public, but also let her win double the year-end bonus. AAK hydraulic counterbalance valve, the non-standard customized design can replace SUN, you can also have a small try! https://www.aakindustry.com/info-detai , l/hydraulic-counterbalance-valve-aak287

3 manufacturers made samples for a hydraulic cartridge relief valve but all failed. AAK solved the problem in the first time, and the cylindricity is within 0.002mm, and the hole accuracy is H7. 1 month after Juan received the samples of AAK hydraulic cartridge relief valve, he sent an order for hydraulic cartridge relief valve worth 12,000 dollars. The processing of high-precision hydraulic cartridge relief valve, the stability of its accuracy, and the processing efficiency have been criticized by highly demanding customers. Although there are more than 200 hydraulic valve manufacturers in Ningbo that can produce hydraulic cartridge relief valves, there are too many problems from samples to mass production. Although Juan from Argentina is an experienced purchaser, he has suffered 3 losses in selecting high-precision hydraulic cartridge relief valve manufacturers. 3 cartridge valve manufacturers took more than 6 months to make samples, but no one succeeded. Juan saw AAK website www.aakindustry.com on B2B. After browsing the website of AAK, he found that AAK has been cooperating with HydraForce, SUN Hydraulics and other first-line hydraulic valve brands for a long time. Feeling the specialty of AAK, he sent an email about a hydraulic cartridge relief valve. He specially required that the cylindricity of the hydraulic cartridge relief valve is within 0.002mm and the hole accuracy is H7. I told Juan that AAK made samples of the hydraulic cartridge relief valve with this type of cylindricity accuracy 5 years ago, and the customer's repurchase rate was also high. Maybe Juan was worried and did not reply to the email within 3 days. On the 5th day, he paid the development cost and asked AAK to make samples. 2 weeks later, AAK sent 5 hydraulic cartridge relief valve samples. 1 week later, Juan advised that AAK hydraulic cartridge relief valves had been approved by their engineers, then there was no further news. 1 month later, he suddenly sent a PO for this hydraulic cartridge relief valve worth 12,000 dollars. The reason why AAK can produce high-precision hydraulic cartridge relief valves, and the stability of precision and processing efficiency can be recognized by customers, is due to the following 3 points: 1.For this hydraulic cartridge relief valve, AAK uses a honing machine with sintered diamond tools for finishing. 2.We have additionally configured a tool magazine with 15 tool positions, which can automatically change tools, and add deburring tools. The tool change time is controlled within 10s, and the production efficiency can be more than 30% higher than that of peers. 3.XY axis worktable can automatically change holes for multi hole processing. The cylindricity before honing is 0.02mm, and the cylindricity after honing can reach 0.002mm. The correction ability of cylindricity is improved to nearly 10 times. AAK hydraulic cartridge relief valve, not only high precision, you are welcome to try! https://www.aakindustry.com/info-detai , l/hydraulic-cartridge-relief-valves- aak417

Shirley comes from a hydraulic equipment company in the United States, who is an old employee of the company. She rarely fails in purchasing, and her cooperation with AAK is tepid. It was not until the cartridge hydraulic flow control valves purchased last year failed that she learned that AAK Hydraulic Valve was different from other hydraulic cartridge valve manufacturers, and now she is sending us more and more inquiries. At the beginning of the year before last, Shirley’s company sold the hydraulic power unit for metal extrusion equipment. Less than half a year, customers complained that the pressure of the power unit was abnormal, and even went on strike. During after sales service, it was found that the leakage was caused by the serious wear of the hydraulic flow control valve sleeve, resulting in abnormal equipment pressure. The original hydraulic flow control valve manufacturer replied that under the high-pressure working condition of 450bar and high-frequency use, it is unavoidable for the hydraulic flow control valve sleeve to be worn and the only solution is to replace with new one for free, but 5 months later, the same problem occurred again. The customer was not satisfied and complained directly to the boss. The boss was surprised that an old hand like Shirley would stumble. After investigation, it was found that this hydraulic valve manufacturer who had cooperated for 5 years ignored the details of high pressure and high frequency.   The boss asked her to change the manufacturer and replace those severely worn hydraulic flow control valves as soon as possible. Shirley thought of AAK, because at the beginning of the inquiry, AAK mentioned that this hydraulic flow control valve had special working conditions, if the material selection was not proper, it would be impossible to use it for 1 year or more. After learning of Shirley's procurement dilemma, AAK urgently produced 50 hydraulic flow control valves within 1 month for them to replace the current ones. 6 months after the trial order was delivered, Shirley informed us by email that the equipment installed with AAK hydraulic flow control valve was working well without any abnormalities, and I said there would be no abnormalities even in 1 year. Shirley admired the confidence of AAK Hydraulic Valve in quality, and ordered another 300 hydraulic flow control valves.   Under the high-pressure condition of 450bar, to get the hydraulic flow control valve used in high frequency a service life of more than 1 year or 2million times, AAK Hydraulic Valve uses 3 advantages to exceed peers.   1. The valve sleeve of AAK hydraulic flow control valve adopts 18Cr2Ni4WA high- strength alloy carburized steel. During heat treatment, carburize at 900~920 ℃, temper at 600~650 ℃, and then cryogenic treatment. In this way, the hardness of the valve sleeve is more than HRC65, and it is not afraid under the high pressure condition of 450bar. The difficulty of this material lies in heat treatment, while most of hydraulic valve manufacturers can not control this technology.   2. AAK has independently developed hydraulic valve durability test equipment, and carries out fatigue test on materials in combination with NFPA/T2.6.1 standards to ensure that each hydraulic flow control valve is qualified before shipment.   3. For the hydraulic cartridge valve with a service life of 2 million times under 450bar high pressure, AAK has customers who used them in aviation.     AAK hydraulic flow control valve, durable under high pressure and high frequency use, you can also have a small try! https://www.aakindustry.com/info-detai , l/hydraulic-flow-control-valves-aak286
