AAK Hydraulic Flow Control Valve, 2 Million Times of Service Life

Margaret is from a hydraulic equipment company in the United States. At the end of last year, some of their drilling rigs were complained by customers that they were unable to work. The problem was the leakage caused by the wear of the hydraulic flow control valves. The original hydraulic flow control valve manufacturer said that due to long-time high-pressure and high-frequency operation, the wear of the valve body is difficult to avoid, so the hydraulic flow control valves can only be replaced. After half a year, the fault occurs again, and it seems that the hydraulic flow control valves can only be replaced once every half a year. After the boss knew about it, he was not satisfied with this high frequent after-sales service. He asked Margaret to find a new hydraulic flow control valve manufacturer, and added the parameter requirements of high pressure resistance in the inquiry. In the first round, Margaret contacted with more than 10 hydraulic valve suppliers that she was satisfied with in the past, and only 3 said that they could have a warranty period of half a year to 1 year under high pressure. Margaret should not be satisfied with this reply either. After being introduced by one of our old customers, she contacted me. I suggest that she use durability to measure the service life of hydraulic flow control valves. After communicating with their engineers, she requested that the durability of this hydraulic flow control valve be more than 1.5 million times. AAK engineers judged that according to their working conditions and pressure requirements, the material selection of this hydraulic flow control valve is very important, especially the valve body material. After 40 days, AAK sent 10 samples of hydraulic flow control valves. More than 2 months later, Margaret emailed that the durability tests of 3 factories and AAK hydraulic flow control valves had failed. Before sending samples, our engineers tested each hydraulic flow control valve, and the durability of 1.5 million times is unlikely to fail. After checking with Margaret, it was learned that their boss specially asked the engineer to increase the durability test from the original 1.5 million times to 2million times. Margaret said that the other 3 factories have given up re testing, and asked whether we are willing to continue testing? AAK is most willing to do what its peers are unwilling to do. Three months later, the samples of the hydraulic flow control valves were sent again. Last week, Margaret said in an email that AAK hydraulic flow control valves passed the test and is the only manufacturer that can adhere to the samples for half a year. Their teams are convinced that AAK is obsessed with manufacturing quality. The boss was also very satisfied that she found a professional hydraulic flow control valve supplier like AAK. Over the past 13 years, AAK technical team has gained an experience that every customer thinks that the problems they encounter are individual and unique. In fact, we have already solved them here. Why do you have personalized questions? That's because none of your peers can help you solve it, let alone promise. During the test sample period, AAK engineers worked for more than 14 hours every day. After repeated defeats, they finally determined 3Cr3Mo3W2V hot work die steel as the valve body material and made special treatment on heat treatment. The mechanical stress is more than 10 times that of other steels. The hardness, strength, wear resistance, stability and thermal conductivity are completely consistent in the whole material section, so as to ensure that the hydraulic flow control valves can pass the test of 2million times under high pressure. AAK hydraulic flow control valve, 2 million times of service life, you can also have a small try! https://www.aakindustry.com/info-detai , l/hydraulic-flow-control-valves-aak266

AAK Hydraulic Cartridge Pressure Control Valve Cage Accuracy 2μm

Last March, Jhon from Canada left a message on the hydraulic cartridge valve manufacturer AAK website: Is your valve cage processing using Japanese equipment? It is the first time for me to notice such a message. After several rounds of communication, I learned that the hydraulic cartridge pressure control valves that Jhon purchased from the original manufacturer had unstable accuracy cages, which posed a problem to their equipment. He wants to find a hydraulic cartridge valve manufacturer who can control the valve cage accuracy of each hydraulic cartridge pressure control valve within 2μm. I told him that the accuracy of the valve cage of the hydraulic cartridge pressure control valve depends on the production equipment, but it is also related to the technician and the quality system of the factory, especially for non-standard hydraulic cartridge pressure control valves. Hydraulic cartridge valve manufacturer AAK can use Japanese imported equipment from Hasegawa to produce the valve cage of his hydraulic cartridge pressure control valve. Jhon seemed to see hope, and the next day, we received the trial order for his hydraulic cartridge pressure control valves. After 40 days, AAK sent out the samples of the hydraulic cartridge pressure valve as scheduled. Last weekend, Jhon emailed us to inform that the hydraulic cartridge pressure control valves shipped by AAK have been installed on their equipment for 8 months. The stability of the precision of the valve cage of the hydraulic cartridge pressure control valve has satisfied their engineers. This non-standard hydraulic cartridge pressure control valve cage is machined using the Japanese imported Hasegawa lathe used by AAK. The structure of the equipment can achieve ultra-low vibration machining, and it is equipped with a CNC parking system, which ensures the stability of machining accuracy. At the same time, its rotational speed can reach 30,000 revolutions per minute, and the 12 position turret can be freely matched with a powered tool handle, which is highly favored by our technicians for its flexibility in processing. After each valve cage is processed, AAK operators will use a micrometer caliper to measure the machining dimensions of each valve cage. AAK hydraulic cartridge pressure control valve, machined by Japanese equipment, with accuracy within 2μm. You can also give it a try.

AAK Hydraulic check valve, O-ring that does not fall out of groove and wear

Last week Logan said that he needs to order 1,000 hydraulic check valves at one time and asked me to hurry up to prepare materials. After reading this email, I felt very good. Logan comes from a Canadian hydraulic equipment company. Two years ago, he found AAK Hydraulic Valve on the Internet. The hydraulic elevator to be developed by their company needed to use special hydraulic check valves. He asked AAK to make 20 hydraulic check valve samples urgently according to his drawings, and promptly paid the development cost. According to the drawing, the O-ring of the hydraulic check valve is a little special, and each component needs to be customized. It took more than 2 months for AAK to successfully finish and send 20 hydraulic check valves. Strangely, after samples were sent, there was no news in 9 months until Logan's email last week. Logan also frankly told us why we did not receive the feedback until now. It turned out that their company had selected 3 factories to test the samples of this hydraulic check valve. In the first test, the samples from all the 3 factories reached the standard, so they chose the cheapest one to place an order. Six months later, they knew the trouble was coming. The customer reported that the lift was unable to rise. After checking, it was found that the hydraulic check valve leaked and did not maintain pressure. The reason for the leakage was that the O-ring of the hydraulic check valve was out of the groove and worn. Logan contacted the original hydraulic check valve manufacturer, and the manufacturer replied that the O-ring was a quick-wear part. If the customer used it frequently, the quick-were part needs to be replaced every 6 months, and the O-ring replacements can be provided free of charge. However, in such frequent after-sales, the sealing ring is a small amount of money, but the after-sales cost is the big trouble. Moreover, the customer may not accept it. Logan checked the original archived samples again to verify the reliability of the O-ring of the hydraulic check valve, and found that the O-ring of AAK was different from that of other manufacturers. He also remembered that AAK was the latest one to deliver samples at that time. Their engineers compared and tested the O-ring of the hydraulic check valves again, and found that the O-ring of AAK was not only different in material, but also different in structure. How does AAK do it? The selection of O-ring should not only be based on the working conditions of hydraulic check valve, but also strictly control the size. With the special design of this hydraulic check valve, the pressure on the O-ring comes from the inside. The outer edge of the O-ring will contact the outer edge of the groove. The compression ratio can only be between 1% and 3%. Considering that the shrinkage of the O-ring will cause tolerance, AAK has customized samples for 8 times to determine the allowable tolerance range of O- ring, which is 15% higher than DIN 3771 and ISO 3601/1 standards. Finally, the ultra wear-resistant PU polyurethane rubber O-ring with reasonable size was selected, and it was guaranteed that the O-ring would not fall out of groove and wear within 1 year. AAK hydraulic check valve, with O-ring that does not fall off groove and wear, you can also have a small try! https://www.aakindustry.com/info-detai , l/hydraulic-check-valve-aak265

AAK Proportional Cartridge Valve Benchmarking HydraForce TS08-27

Recently, we launched a hydraulic proportional cartridge valve equivalent to HydraForce standard part TS08-27. It is a pilot operated spool type, proportional pressure relieving valve. The regulated pressure is inversely proportional to the input electrical current. Last February in 2022, a hydraulic cartridge valve customer in Russian found AAK when looking for a hydraulic cartridge valve manufacturer in China on Google. He sent us an inquiry for 20 pcs of HydraForce Pressure Relieving Proportional Cartridge Valve TS08-27. For this model, very few cartridge valve manufacturers in Ningbo have existing production procedures. At that time, AAK was still in developing it for a listed company in Canada. We told the Russian customer that after the development is finished, AAK still needs at least 1 year to test the function and performance. We will keep you informed when this Pressure Relieving Proportional Cartridge Valve passed the 1 year of durability testing. This June, we were very happy to learn from the Canadian customer that AAK Pressure Relieving Proportional Cartridge Valve E-TS08-27 has passed their internal testing after 1 year of use, they are preparing for the 2024 buy plan and will send us the official order very soon. After knowing this, the Russian customer asked us to quote based on an annual order qty of 500 pcs directly. Today, we received the official PO for it. AAK hydraulic pressure relieving proportional cartridge valve 2 advantages: 1. Hysteresis per cent ﹤3%, benchmarking HydraForce quality 2.

AAK Hydraulic Pressure Reducing Valve Durability Exceeds German factory

Edmund from Germany has purchased hydraulic valves from AAK for more than 3 years. He emailed me a question this morning: the SiCr alloy steel pressure spring is used in hydraulic pressure reducing valves, and its durability can not reach 1million times or more? I asked him why he suddenly asked so? He frankly told me that he had encountered problems when purchasing hydraulic pressure reducing valves from Germany factory. At the same time, he also saw an article of AAK that " For hydraulic pressure control valves that German manufacturers were unwilling to solve, AAK used special spring to ensure a service life over 1 year”, so he wanted to discuss it with me. At the beginning of last year, the hydraulic pump of the excavator they sold often had insufficient startup pressure. The problem lied in the hydraulic pressure reducing valve of the hydraulic pump. The pressure of the hydraulic system was unstable because the pressure spring of the hydraulic pressure reducing valve was deformed. Since this excavator has been in use for less than 1 year but the hydraulic pressure reducing valves must be replaced. Edmund contacted the local original manufacturer to replace several hydraulic pressure reducing valves. The manufacturer replied that the hydraulic pressure reducing valve was produced according to the standard, and the strength limit and elastic limit of the piano wire used for the spring were in line with the requirements. The problem was that the user's use frequency and working pressure were too high, problem was caused by improper use. This time, they were willing to replace it for free, and they would have to pay for it next time. Edmund is aware that if there is a complaint about one device, there may be a complaint about the second one. This time, the replacement of the hydraulic pressure reducing valve can only solve the current problem. Edmund began to contact nearly 20 manufacturers of hydraulic pressure reducing valves. Most of them said that the spring made of piano steel wire was the best material. Edmund asked several factories to provide samples for testing to simulate the high frequency and high pressure of excavators. After more than 2 months of durability testing, the durability of the spring failed to pass 1 million times, and basically began to be unstable after 400,000-600,000 times. I joked that he found the right person to solve this problem. The spring of piano steel wire is indeed a good material, but good materials do not necessarily produce good finished products. We strictly follow 3 steps in the selection of spring. The pressure spring of this hydraulic pressure reducing valve really needs better materials to pass the durability of 1 million times. AAK Hydraulic Valve began to innovate the pressure spring 1 year ago. At the request of the customer, AAK technical team spent 24 days, tested samples for 6 times, compared 3 kinds of springs with good elasticity, and selected the special SiCr alloy steel spring, which can pass the durability of 1 million times. SiCr alloy steel spring has high temperature resistance, high rigidity, anti relaxation and long service life. It can be used for 1 million times under high stress conditions. Edmund asked me to send samples. According to his hydraulic pressure reducing valve drawings, I told him that samples could be sent in 4 weeks. I also told him that using AAK hydraulic pressure reducing valve with SiCr alloy steel pressure spring, he would no longer have to worry about complaints. AAK hydraulic pressure reducing valve is protected by special SiCr alloy steel spring under high stress, with a service life of 1 million times. You can also have a small try! https://www.aakindustry.com/info-detai , l/hydraulic-pressure-reducing-valve- aak264

AAK Hydraulic Relief Valve, High Pressure Resistant and Long Service Life

Last Monday, Yvonne ordered 1,000 hydraulic pilot operated relief valves and stressed that all parameters should be in line with the hydraulic relief valve samples of last year. It seems a little strange. After we sent the samples last year, Yvonne said that the parameters were up to standard, but the plan changed. She would no longer purchase this hydraulic pilot operated relief valve. After several rounds of communication, it was learned that Yvonne changed the manufacturer last year and had suffered a loss, so she returned to AAK to make up the order. Yvonne, from a Canadian equipment company, started cooperation with AAK last year. At the beginning of last year, their company planned to develop a hydraulic power unit, which needed to purchase a hydraulic pilot operated relief valve. After a round of screening, Yvonne chose 3 hydraulic relief valve manufacturers to test samples, and AAK was one of them. Finally, Yvonne placed the order with the hydraulic relief valve manufacturer with lowest price. In more than half a year, customers complained that the hydraulic pressure of the equipment was unstable. The pilot operated relief valve in the system is used as a safety valve, but the valve spool and valve body are worn and the coaxiality is deviated, resulting in abnormal valve opening and sharp rise of system pressure, resulting in equipment failure. According to the feedback from the manufacturer of the original hydraulic pressure relief valve, this hydraulic pilot operated relief valve needs to meet the high-pressure working condition of 450bar and cannot withstand such high- frequency use. It can only be guaranteed the service life of half a year, and has to be replaced every half a year for after-sales service. The boss was not satisfied with the half year service life of this manufacturer and asked to change the hydraulic relief valve supplier. According to the records of the after-sales department, Yvonne found that among the samples from 3 factories, only the equipment installed with AAK hydraulic relief valve has no complaint record. The service life of the other one was about 10 months, but AAK was normal after 1 year. I told Yvonne that according to previous customer cases, the 18 month service life of this type of hydraulic relief valve under 450bar high pressure is not a problem, because we are benchmarking the service life of 2 million times of HAWE. She also wants to know why the service life of AAK hydraulic pilot operated relief valve is better than that of other factories? The selection of materials is the key to resist 450bar high pressure. Generally, AAK selects A+ material to replace the A material used by the international top brands. For example, the 20crni2mov high carburized bearing steel imported from Germany, is used as the valve spool of this hydraulic relief valve, combined with the carburizing pretreatment process, through the secondary quenching + cryogenic treatment + low temperature tempering process, it is cooled to 650 ~ 700 ℃ and then discharged after it is cooled to 450 ~ 500 ℃. The microhardness is 237 ~ 247 HV, and its wear resistance and contact fatigue performance are increased by more than 3 times, so the wear of valve spool is no longer worried. Yvonne privately told us that the boss was very satisfied with her ability to quickly solve problems. AAK hydraulic relief valve with a service life of 2 million times will be their fixed supplier in the future. AAK hydraulic pilot operated relief valve, is high pressure resistant, with 2 million times of service life, you can also have a small try! https://www.aakindustry.com/info-detai , l/hydraulic-relief-valve-aak263

AAK Hydraulic Valves High Precision Long Service Life

Nowadays, people's recognition of the quality of "Made in China" products is much higher than that of 10 years ago. In fact, this recognition is still lagging behind. For example, the Chinese hydraulic valve manufacturers at the head can rank among the top 20% of the world's hydraulic valve industry only from the manufacturing quality of hydraulic valves. This is also an explanation for why Sun hydraulics directly import finished products from China. I believe that in 10 years, the hydraulic valves engraved with "Made in China" will account for more than 70% of the weight. AAK Hydraulic Valves, 13 years ago, changed from a hardware enterprise to hydraulic valve production. We started with the manufacturing process and learned by doing. We paid a lot of tuition fees and accumulated the production technology and experience of hydraulic valves. Then slowly improve the technology according to their own production needs, refit some equipment and create some patents. Until now, the sales volume of hydraulic valves has gradually expanded, and AAK technology has gradually moved forward. At the same time, more resources have been invested in research and development to promote more basic and wider application of hydraulic valves. In a word, there is no strong hydraulic valve manufacturing, others are floating clouds. In industrial manufacturing, there is no major technological innovation country in the world that did not start with a major manufacturing country (at least once). The advantages of China's hydraulic valve manufacturing industry chain have been self reinforcing in recent years, and continue to attract first-class hydraulic valve brands in the supply chain to set up factories in China. AAK has been OEM factory of hydraulic valves for 3 of the world's top 500 companies for 10 years. The quality control process is more strict than the ISO certification system. It sticks to the manufacturing details of hydraulic valves, focuses on process innovation, and insists on technology research and development. Ensure that each hydraulic valve has anti fatigue, high precision and long service life. What I want to say to the domestic hydraulic valve counterparts is that 20% of the hydraulic valve manufacturers already have quality awareness. What should the remaining 80% of the manufacturers do? Many domestic hydraulic valve peers lack concentration and patience, and specialization is to follow. Because in the past, when we set up enterprises, we could still make money by taking one shot at a time. The vast majority of hydraulic valve manufacturers are money worshippers, not technology worshippers. The vast majority are short-term, not long-term. In the past, they could survive and make money. However, after the construction of the national unified market and under the background of the globalization of industrial products, this kind of thinking will be completely over and impossible. In Japan's manufacturing industry, there is a word called "life dedication", a whole life for one thing. This is the Japanese concept. In fact, the Germans are the same. They have focused on one category or variety for decades or even hundreds of years. This is also the reason why they both are top ones in cutting-edge manufacturing. This is also the direction of AAK Hydraulic Valves. A group of people only work on hydraulic valves all their lives. There is another word in Japan called "one product into the soul". In order to make this product, the soul must be cast into it. To make a product, we should be attentive and soul-bound. I think that "life dedication " and "one product into the soul" constitute the core connotation of Japan's invisible champion. AAK is aiming at the invisible champion of Chinese hydraulic valves, and it acts the same. AAK Hydraulic Valve always focuses on 3 directions, the first is focus, the second is innovation, and the third is internationalization. Globalization is a trend of historical development. Although there are some effects against globalization, the historical trend will not change after all and will not be transferred by people's will. AAK puts "focus, innovation and internationalization" into the soul of the anti fatigue, high precision and long service life hydraulic valves. This is our way. The right way is not far away. https://www.aakindustry.com/info-deta , il/hydraulic-valves-aak262

AAK Hydraulic Cartridge Valves Reasons to Buy

This Sunday today, there was some time in the morning. My son Steven didn't have any training classes this morning. Most of the Chinese children are always taking cultural classes, or on their way to interest classes on weekends. Steven asked me to take him to a snack street near home for breakfast, but he hasn't figured out what to eat yet and will decide there. I usually already have a plan about what to have for the breakfast when getting up, such as having rice noodles or bread today, then go to the breakfast shop, buy it and leave. I won't think hard at the entrance of a few bakeries or a few noodle stalls. I don't think most people would do this. But today, I was walking from beginning to end with my son on this breakfast snack street for over 10 minutes, because I was free today. This snack street is actually my first time here, and I don't know which one is good or bad. Suddenly, I saw a sign "time-honored brand soup with pepper", which attracted me. Steven also wanted to try the soup with pepper he hadn’t eaten before, so we went in. Breakfast is a fast moving consumer product that everyone is familiar with. Unlike hydraulic cartridge valves, which are unfamiliar to most people. Fast moving consumer goods are cheap. It's so cheap that the brain doesn't have to think, and just buy it based on intuition, common sense, and instant reaction. I sat down, stopped, and thought, 'There are dozens of people eating breakfast on this street, why did I choose this one? I was attracted by time-honored brands, which are local characteristics and also with traditions. Sure enough, the boss came to introduce them. Their soup with pepper came from the Qing Dynasty and has a history of 120 years. And their innovative soup with pepper, Jack Ma of Alibaba has come to eat it. This boss really knows how to do business. Although I am not a breakfast maker, we can learn from breakfast about the production and sales of hydraulic cartridge valves. What am I thinking when I buy mineral water, instant noodles and web paper? What is the customer thinking when purchasing hydraulic cartridge valves? To think from the customer's perspective, in marketing, one must understand this matter. Why don't customers buy from the peers, but from me? I believe many people haven't thought about this issue. AAK hydraulic cartridge valve is usually promoted online, focusing on the specific content of the hydraulic cartridge valve. I write hydraulic cartridge valve tweets every day, but our sales team probably didn't specifically think about why customers want to buy AAK hydraulic cartridge valves? From accompanying my son for breakfast, my harvest is that fast moving consumer goods mainly depends on the selling points. I rely on intuition, try and a split second, because the store caught my eye. A book by a marketing guru that captures users' minds and relies on a differentiated selling point, I think that's the logic behind it. For example, there is an advertisement for Swiss chocolate: it only dissolves in the mouth, not in the hands. After breakfast and on the way back, I was thinking, can you use an advertising slogan for AAK hydraulic cartridge valves? It seems possible, but it seems impossible. Because hydraulic cartridge valves are not fast moving consumer goods, but durable industrial products. However, the promotion of AAK hydraulic cartridge valves must have a sense of scale, so that online customers can see the shadow of AAK hydraulic cartridge valves everywhere, the selling points of AAK hydraulic cartridge valves, a series of purchase reasons, and the most important trust.

AAK Cartridge Valve Manufacturer Care to Customers with Heart

Adam, an old customer of AAK Hydraulic Valve, asked me to copy 2 hydraulic cartridge valve samples for exhibition some time ago. After receiving the samples of cartridge valves, I was a little surprised that the surface of the valve body was not heat treated, just the polished low carbon steel raw material. I double checked with him, is it still copied as required by the email, or can AAK improve the appearance of the valve? He just replied: do your best, the samples are for exhibition. I sent samples and refined 3 selling points. 1. The material of cartridge valve body and valve spool is changed to high- strength alloy steel. 2. The surface treatment of hydraulic cartridge valve is galvanized nickel alloy. 3. The durability of hydraulic cartridge valve ensure for more than 2 million times. Why should I do this? In fact, it is due to a small matter I met before. I needed to polish 2 stones. I found a stone polishing studio. They sent the stones back in a week. After I got the polished stones, I felt that they did not polish them attentively. In fact, the requirements for polishing the stones are very simple. As long as you polish it carefully, you can do it well. But they just didn't want to work hard, so they sent stones back after dealing with them. I'm a little surprised. The studio seems to be of high quality. Why can't they do this little thing well? Adam needs hydraulic cartridge valve samples to participate in the exhibition. The manufacturing quality, function stability and performance durability of such products must be considered. After Adam got the hydraulic cartridge valve samples, he told me that he had 3 hydraulic cartridge valve manufacturers copy 10 hydraulic cartridge valve samples. Only AAK made improvements on the basis of the original, and helped him extract 3 selling points, while others just completely copied the original. 2 months later, Adam told me that the 2 models of hydraulic cartridge valves copied by AAK had the most inquiries. No matter my customers and I, or my suppliers and I, we are "working together", but just the office is different. No matter who, no matter how: 1. You can do any work as long as you do your best. Doing your best is the easiest way to work. 2. If you are absent-minded, you may lose a customer you can cooperate with for a long time, and then continue to complain about the difficulty of business.   In fact, most of the work has little technical content. As long as we do our best and work hard, we can do a good job. But most people just don't want to do more and think more, which leads to their failure in work and dissatisfaction of the boss. In fact, they can take their work seriously and carefully, and then get higher pay. But they are not. They are slacking off and dealing with their work casually, while complaining about how hard life is and how unrecognized talented they are. Our corridor part-time cleaning aunt, the property did not require her to work on weekends, because there were not many people on weekends, but occasionally some people worked overtime. I often see her on weekends. I asked her curiously, "Are you coming on weekends?" She naturally replied that I have nothing to do at home, so I come to see if there is any place that needs cleaning. This is the difference between attentiveness and inattentiveness. AAK Hydraulic Valve, treats every old customer with care from a small matter, and will meet new customers with more care. https://www.aakindustry.com/info-deta , il/cartridge-valve-manufacturers-aak482

AAK Hydraulic Cartridge Valve Manufacturers Stratified like Society

Yesterday, hydraulic cartridge valve manufacturer AAK defined some people as the bottom of society, although it is quite distressing, this is also a fact. In Ningbo, although there are over 200 of hydraulic cartridge valve manufacturers, most of them are at the bottom of the industry. People are stratified, and hydraulic cartridge valve manufacturers are also stratified. People at the bottom of society are almost always those who do not like to use their brains, and their perception of life is relatively shallow. Easy to move and angry, but usually comes quickly and goes quickly. They are deeply moved when others helped them, and at that moment, they were sincere. But they superficially believe that a "thank you" from themself can be equivalent to someone else's deep affection. The root cause is that they do not understand that the underlying logic of society is "equivalent exchange", and their gratitude becomes particularly cheap. If you provoke them, they do care about your past interactions and the help you gave them, and immediately turn again you mercilessly, because they really can't hold back. Even if there is a cost of having their tongue cut off afterwards, they must speak out what they want to say. Recently, a client of mine found a new valve from a hydraulic cartridge valve manufacturer in Ningbo, for AAK did not have the existing program for this valve, he had to purchase it from that manufacturer. This hydraulic cartridge valve manufacturer seems to have just started foreign trade and has received a foreign trade order. He treated my client very well and was also very grateful. 2 months later, upon receiving the bulk shipment from this hydraulic cartridge valve manufacturer, my client requested a refund and return due to unstable quality. However, the manufacturer seemed to disappear and did not respond to emails or phone calls. My client asked me to help negotiate with the hydraulic cartridge valve manufacturer, so I saw the email communication between the client and this hydraulic cartridge valve manufacturer. This manufacturer went from treating customers as gods to trampling them underfoot, just in a moment of thought. People at the bottom of society are like neighbors in a large courtyard. As long as their own interests are not involved, neighbors will be very enthusiastic and helpful to each other. However, when it comes to their own interests, even if they are brothers, they will fight against you. Hydraulic cartridge valve manufacturers at the bottom of the industry are like people at the bottom of society. As long as you influence their interests, whether you are their customer or their supplier, you become their enemy. I like to interact with bookworms who love to "use their brains", not only because of their sense of propriety, but also because they don't waste time and are controllable. The same goes for partners in business, if your supplier is from the bottom of society and is just a brainchild, such uncontrollable cooperation is like walking on a tightrope. AAK, a Hydraulic cartridge valve manufacturer in China, loves reading and has a brain. Live thoroughly and do professionally.

AAK Hydraulic Cartridge Directional Control Valve Load Balance

Stephen is from a hydraulic equipment manufacturing company in Greece, and his 3-year procurement is very successful. At the beginning of the year, their customer customized the company's large tonnage cranes, with very high requirements for hydraulic cartridge directional control valves. Stephen chose a local hydraulic cartridge valve manufacturer who has cooperated with him for 3 years to make samples. During the prototype debugging, the connecting pipeline of the oil cylinder burst, causing the boom to drop abnormally. Their engineers advised that the key is to optimize the load balance of the hydraulic cartridge directional control valve. The manufacturer said that this hydraulic cartridge directional control valve benchmarks a standard part of HydraForce and cannot be improved. Stephen contacted more than 10 hydraulic cartridge valve manufacturers, but none of them was willing to improve the standard parts of HydraForce. Stephen was very worried. Stephen found AAK while browsing Google. He noticed that AAK was continuously supplying HydraForce and left a message: Can AAK optimize the hydraulic cartridge directional control valve of HydraForce standard parts? I guess that he encountered trouble in purchasing hydraulic cartridge directional control valves. After communication, I learned the story above. According to his hydraulic schematic diagram, production drawings of hydraulic cartridge directional control valve, and equipment work videos, AAK engineer said that the original system was designed as a double cylinder luffing structure. During the luffing operation, the cylinder motion was not synchronous. When the system was suddenly loaded, the double cylinders were biased and the pipeline burst. Only by optimizing the structure of the hydraulic cartridge directional control valve can the load balance of the system be improved. Stephen saw the hope and paid the development cost on the second day. After 35 days, AAK sent 12 samples of hydraulic cartridge directional control valves. 2 weeks later, Stephen informed by email that after replacing with AAK hydraulic cartridge direction control valves, the prototype debugging was smooth, no pipeline burst, and the equipment had been delivered to the customer. After the customer tried, there would be an official order. AAK optimized the structure of the hydraulic cartridge directional control valve, and set small tricks on the first and second oil ports of the valve body. The oil passage between the first oil port and the valve chamber is equipped with a detachable damper, and the inner wall of the valve chamber at one side of the second oil port is provided with a boss extending radially. After this optimization, the oil pressure connected to the first oil port and the second oil port of the valve can act on both ends of the valve spool respectively, and the valve spool can slide between the first working position and the second working position under the action of the pressure oil. When the valve spool is in the first working position, the first oil port of the valve body is connected to the second oil port, and when the valve spool is in the second working position, the oil path between the first oil port and the second oil port of the valve body is not connected. AAK hydraulic cartridge directional control valve, no longer need to worry about safety, you can also try a small order! https://www.aakindustry.com/info-det , ail/hydraulic-cartridge-directional- control-va , lves-aak413

AAK Hydraulic Cartridge Pressure Control Valve Free of Impact Load

Balram is from a hydraulic equipment manufacturing company in Chile. The purchase of 3 years has been smooth, but the recently purchased hydraulic cartridge pressure control valve has upset him. The hydraulic cylinder supplied by them was complained by a customer, the hydraulic shock caused serious vibration of the pipe, which was easy to crack and leak oil. It is judged by the after-sales that it was caused by the impact load of the hydraulic cartridge pressure control valve used to control the pipeline pressure of the oil cylinder. The impact load of the hydraulic cartridge pressure control valve must be reduced. The hydraulic cartridge pressure control valve manufacturer advised that the impact load cannot be avoided. Balram checked with different hydraulic cartridge valve manufacturers in China to solve the impact load of the hydraulic cartridge pressure control valve. A week later, it was still fruitless. Balram browsed AAK website on Google and clicked the articles or products about hydraulic cartridge pressure control valves for many times. He left us a message: How to reduce the impact load of hydraulic cartridge pressure control valve? My reply: There are many reasons for the problem, which should be analyzed in detail. According to the video of abnormal equipment sent by Balram, as well as the production drawings of hydraulic cartridge pressure control valves, AAK engineers judged that the structure should be optimized and AAK is 90% confident to be successful. Balram saw the hope and asked AAK to make samples. After 35 days, AAK sent 12 samples of hydraulic cartridge pressure control valves. Last week, Balram said that it had been 9 months since AAK hydraulic cartridge pressure control valve was used on the hydraulic cylinder, and the pipeline was free of vibration and cracking. The customer was very satisfied with this after-sales service. His boss has decided to replace all the hydraulic cartridge pressure control valves on this batch of hydraulic cylinders with AAK ones, so AAK can prepare materials in advance. According to the schematic diagram provided by Balram, AAK optimized the original structure of the hydraulic cartridge pressure control valve. It can realize small opening throttle back pressure, and meet large opening oil return to reduce pressure impact. It can effectively reduce the peak value of pulsating pressure impact generated by high-frequency commutation, avoid pipeline vibration impact damage, and reduce the impact load on the connection between the vibration table and the hydraulic cylinder. AAK made below 3 changes: 1. A cavity with a stop is formed between the upper part and the lower part of the valve body, and the upper end of the valve spool in the cavity is against the positioning nut. 2. A sliding block is arranged in the middle of the valve spool, a stop is arranged at the lower part, a pressure regulating spring is arranged below the stop, and the pressure regulating spring is fixed on the spring seat. 3. The spring seat is pressed on the plug, with an adjusting bolt in the middle. One side of the lower part of the valve body is provided with a radial oil inlet hole and an axial control hole connected with it. The other side is provided with a radial oil return hole, a damping hole and an axial oil return hole connected with both holes. The axial control hole is connected with the upper oil hole on the shoulder of the upper valve body. AAK hydraulic cartridge pressure control valve, no impact load, you can also have a small try! https://www.aakindustry.com/info-detai , l/hydraulic-cartridge-pressure-control- valves- , aak412
