Connor is from a Canadian agricultural machinery equipment company, mainly responsible for purchasing hydraulic components. In the second half of last year, the sales of one of their rotary tillers were poor. Users reported that the equipment was insensitive and inefficient, and the fuel consumption was 10% higher than that of the same type of equipment. The boss realized that there were hidden dangers in the hydraulic manifolds and asked the engineers to check the causes. However, more than 1 month had passed and there was no practicable plan. The boss was worried and asked Connor to contact the original hydraulic manifold manufacturer to see if they could provide technical support, but they were only good at producing hydraulic manifolds according to the drawings. Connor also asked all his manufacturers of hydraulic components, but none of them gave a plan. When Connor reported these to his boss, he could only helplessly look at his boss shaking his head. Connor browsed AAK website, saw the display and introduction of hydraulic manifolds, and left a message: what is the relationship between hydraulic equipment with high energy consumption and slow response and hydraulic manifolds? I understood that Connor had a problem with hydraulic manifolds, but it was difficult to answer. After several communications, I learned that his boss was worried, and Connor wanted to solve the problem that had plagued his company for nearly 3 months. According to the hydraulic manifold drawings and the video of rotary tiller work sent by Connor, AAK engineers had discussion. The probability was that the hydraulic manifold design had hidden problems. From the analysis of hydraulic manifold and system schematic diagram, there were certain energy conflicts between the design of some oil circuits and the selection of hydraulic valves. AAK could redesign the hydraulic manifold to match their equipment. Connor also readily paid the development cost. 1 month later, AAK sent the hydraulic manifold samples. 2 months later, Connor said that after their rotary tiller was installed with AAK hydraulic manifolds, it was responsive during operation. The operation was more than 20% higher than before, and the fuel consumption was also reduced by 20%. The customer feedback was good, and more and more customers came to try it out. Connor told me privately that he had seen his boss's long lost smile. The boss paid more and more attention to him. He will be promoted to the management next month. AAK hydraulic manifold has 3 advantages, and there may not be a second one in Ningbo. 1. AAK engineers have experience in hydraulic manifold design, especially in oil circuit design. Ensure flow distribution as required, eliminate bypass throttling loss and reduce energy loss. The sensitive oil circuit control makes the equipment easy to control, sensitive and efficient. 2. Hydraulic manifold material selection and proportioning. The material selection of each component from the valve block to the valve is based on the working conditions. The selection and allocation of all valves in the manifolds must comply with the energy principle under the condition that the system principle is met, without robbing energy or wasting energy. Without more than 10 years' experience in hydraulic manifolds, it is difficult to master its essence. 3. We make good use of MDTools software to design hydraulic manifolds. From circuit logic to the functionality of each valve, we can do personalized design and customized production of non-standard hydraulic manifolds. AAK hydraulic manifold makes the equipment flexible, energy-saving and efficient. You can also have a try! https://www.aakindustry.com/info-detai , l/hydraulic-manifolds-aak272

Castel is from Saudi Arabia, and their company mainly sells oil mining machinery. At the beginning of last year, one of their hydraulic platforms was complained, and the equipment went on strike 8 - 9 months later. After checking, it was found that the shoulder and pin hole of the hydraulic cartridge needle valve spool in the system were broken. The hydraulic cartridge needle valve manufacturer advised that the same model of hydraulic cartridge needle valve was supplied to the South American market. Within 1 year, there was no complaint. The manufacturer explained that the brittle fracture of the hydraulic cartridge needle valve spool was caused by the working conditions and working scenarios. The boss was not satisfied with the manufacturer's buck passing, and asked Castel to found a manufacturer whose hydraulic cartridge needle valve can be used for more than 1 year. Based on the requirement of "hydraulic cartridge needle valve can be used in desert with a service life of more than 1 year", Castel started to look for new cartridge valve manufacturers. After 1 week, there was no result. Castel was a little flustered. Castel noticed the article published by AAK in B2B that "AAK hydraulic counterbalance valves have been used in Sandstorm for 12 months, was free of corrosion”, he emailed us to ask if AAK can customize the hydraulic cartridge needle valves used in desert with a service life of more than 1 year. After communication, we learned that he had trouble in purchasing hydraulic cartridge needle valves. The durability of the hydraulic cartridge needle valve is related to the material, but the structure can not be ignored, especially for the complex working conditions, it should be designed specifically. Castel may have seen hope, and asked AAK to make 20 samples of hydraulic cartridge needle valves. After 45 days, AAK delivered the trial order. After the hydraulic cartridge needle valves were sent out for 2 months, there was no information from Castel. I followed up curiously, and he said that the boss would not reply until 1 year later, then there was no information anymore. I almost forgot about Castel. Until last week, he emailed us an order for 600 hydraulic cartridge needle valves, and specially emphasized that the second batch of hydraulic cartridge needle valves should be of the same quality as the trial order, not the best, but should not fluctuate. I agree with that. It's not the best quality, but the stable quality with few failures. Some small faults can be solved as soon as possible, but they are very troublesome if happen again and again. The quality should be reliable, and will not require repair for a year or even longer. Castel said that AAK hydraulic cartridge needle valves can be used for 18 months. Although the price is a little more expensive than the original hydraulic cartridge valve manufacturer, the service life is twice that of the original manufacturer. The sticking point of AAK hydraulic valve is the stability of function and reliability of performance. This hydraulic cartridge needle valve focuses on 3 points: 1. The shoulder of the hydraulic cartridge needle valve spool is increased to the circular radius, which effectively reduces the shoulder stress of the spool and improves the service life of the spool. 2. The pin hole setting is optimized to reduce the alternating influence of the load change on the valve spool stress. 3. The cantilever beam of the wedge structure of the hydraulic cartridge needle valve is changed into a simply supported beam, which increases the stability of the valve spool and can play an anti vibration role to a certain extent. AAK hydraulic cartridge needle valve, safe for 18 months, you can also have a small try! https://www.aakindustry.com/info-detai , l/cartridge-needle-valves-aak414

A customer asked me, is AAK Hydraulic Valve tweeting for flow? AAK Hydraulic Valve is not for traffic, but for trust. The rain is so heavy that it does not moisten the grass without roots. Although the rain is heavy, if there is no root to absorb the rain and dew, the grass and trees will not only be moisturized, but may also be submerged. What AAK Hydraulic Valve needs to do is not to ask how much rain it can rain, but to focus on its own water absorption root.   Ask how much it can rain, which means how much traffic it can have. What is traffic? In the Google search, enter the hydraulic valve manufacturer, and the customers of the hydraulic valves brush it again and again, which is the traffic. There are also many ways to engage in traffic, such as keywords setting, optimization of advertising, return on investment, click cost, display cost, etc. The core is: the higher the price, the better. The price keeps rising until the "flow dividend" disappears. The rain finally became a high- priced tap water that paid for when it was used and stopped when it was not paid.   What should I do? I began to ask, what is the foothold of AAK Hydraulic Valve? AAK Hydraulic Valve attracts new customers with trust, and win the repurchase rate with manufacturing quality. These are the two legs of AAK Hydraulic Valve.   But what about the repurchase rate? In the past, without the Internet, how did AAK Hydraulic Valve at the end of the street come to today step by step? That's because people who have bought AAK hydraulic valves think it's good. They can't help buying it next time. This is the "repurchase rate". One day, when a people heard that a friend needed a hydraulic valve, he could not help recommending AAK. This is the "recommendation rate". The recommended person, because of the good experience, will generate new repurchase rate and recommendation rate, and then the recommended person follows the way. Finally, the re-purchase rate and recommendation rate are rising, and the return rate is getting lower and lower. The name AAK has become a root that can absorb water. But if you really want to have a root that can absorb water, it is not enough to have only repurchase rate and recommendation rate. The most important thing is trust.   What is trust? To purchase hydraulic valve, click search engine in Google search. Guess whether he will input "hydraulic valves, hydraulic valve manufacturers, China hydraulic valve manufacturers" or "AAK hydraulic valves"? This difference is huge. If he is searching for "hydraulic valves", then guess whether the money you spend is the highest bidding price under this keyword. If he searches for "AAK hydraulic valves", then at this time, the natural search results are almost only AAK. So you don't have to participate in the auction at all. Pick and choose, or you. This is trust. Finally, everyone began to realize that the brand building that seemed to be a waste of money is not only worthless, but also directly determines your life and death. When consumers look for "AAK hydraulic valves", you are born. If consumers only look for "hydraulic valves" forever, you will almost die. What's more interesting is that the more sellers who know how to search for keywords, the more they like business flow, the more they will benefit from business flow, and the more they will ignore whether they have water absorption roots. Finally, it is swallowed by traffic.   AAK Hydraulic Valve walks on two legs, focusing on its own water absorption root. https://www.aakindustry.com/info- , detail/hydraulic-valve-manufacturers-aak484

Eustace is from Greece and is still in the probationary period. He almost switched jobs due to a hydraulic cartridge relief valve that has high requirement on roughness. At the beginning of this year, their customer customized a hydraulic manifold, and all hydraulic cartridge valves needed to be purchased by Eustace, except for hydraulic cartridge relief valves. Everything else went smoothly. The original manufacturer sent samples 3 times, but the roughness of the surface of the hydraulic cartridge relief valve spool and cage still cannot meet the requirements of Ra0.1. Eustace was complained about several times by their chief engineer due to delays in procurement time. Eustace left a message on AAK website: Can the roughness of the surface of the hydraulic cartridge relief valve spool and cage be controlled within Ra0.1? After communication, we learned that the original hydraulic cartridge relief valve manufacturer failed for 3 times, which made him very helpless. I told him that the design of their hydraulic manifold requires high precision for the hydraulic cartridge relief valve. If the roughness is not solved properly, the valve spool is prone to jamming. AAK cannot guarantee that the roughness of each processed product is within Ra0.1, but the hydraulic cartridge relief valves to be in the customer's hands must meet the standard. After 35 days, AAK sent out 10 samples. 1 month later, Eustace informed us via email that their hydraulic manifold had been approved by the customer. Before the hydraulic manifold assembly, their technicians tested each hydraulic cartridge relief valve sent by AAK, and its roughness was within Ra0.1. The roughness of the AAK hydraulic cartridge relief valve spool and cage can be controlled within Ra0.1, with precision machining as the core and detection as the key. AAK uses Japan Mitutoyo roughness measuring instrument to check, and a dedicated person is responsible for it. The advantages of this measuring instrument are large measurement range and high accuracy. We do this by first placing the valve spool or cage on a testing glass platform, and the device will directly capture high-definition images. At the same time, when the contact needle scratches the tested surface of the valve spool and cage, although the surface contour fluctuates between peaks and valleys, the contact needle can vibrate up and down along the peaks and valleys, and at the same frequency, the signal is amplified by more than 10 times through an electronic device, and then transmitted to the computer to form data or dynamic images. With this big killer, the roughness Ra0.1 is not difficult. Most hydraulic cartridge valve manufacturers in China do not necessarily have this equipment for detecting roughness, or it may not be 100% full inspection. AAK hydraulic cartridge relief valve, high precision, no jamming, you can give it a try!

The quality of the team of hydraulic cartridge valve manufacturers determines how far they can go. Hydraulic cartridge valve manufacturer AAK has fired two salespeople since the beginning of the year, and they are always able to find reasonable reasons for their inaction and lack of effort. The team of hydraulic cartridge valve manufacturers always has a few people with low cognition. Every time when you communicate with them, you can only sigh that "mud cannot support the wall.". For those who with insufficient cognition, everything you say is in vain. Everyone is paying for their own cognition. If cognition is not at the same level, there is no need to conquer each other. In the world of adults, there is only screening and no education, only selection and no change. If you awaken others, it will only harm your own fortune. Short sighted people lack experience, things they haven't seen, things they haven't experienced, of course they don't believe. This Spring Festival, Ningbo is very cold. I told the child that I can go from winter to summer within 2 hours, but he said it's impossible. I told him to just take a plane. If the child doesn't know about airplanes, how can he understand? People with lower cognition tend to feel more correct and stubborn. There are many small hydraulic cartridge valve manufacturers in Ningbo China, and in their cognition, they think that they only make standard hydraulic cartridge valve parts for retail or wholesale to sell for money. Hydraulic cartridge valve manufacturers with low awareness believe that success is simple, while hydraulic cartridge valve manufacturers with high awareness know that success is difficult, and behind it lies a huge cost and effort. If the manufacturer of hydraulic cartridge valves is not well aware, even if they earn a little money by luck, they will still lose out entirely based on their strength. Manufacturers of hydraulic cartridge valves with low cognitive abilities do things completely according to their own habits, regardless of customer requirements or suggestions. No matter what kind of "golden ideas" he receives, these hydraulic cartridge valve manufacturers don't even want to take a think about it, they just reject them all! Hydraulic cartridge valve manufacturer AAK believes in luck very much. On the road of life, whether you run or read, your body and mind must always be on the road. With such persistence, your luck is likely to get better and better. Reading ten thousand books is not as good as traveling a thousand miles, traveling a thousand miles is not as good as reading countless people, reading countless people is not as good as celebrity guidance, and celebrity guidance is not as good as self realization. In the end, if the hydraulic cartridge valve manufacturer encounters a benefactor, a demanding and meticulous customer, and colleagues are willing to enlighten, then what are the hydraulic plug valve manufacturers worried about? Some hydraulic cartridge valve manufacturers have many scattered customers, but no matter how many customers you have, if they are all at the same level and level of understanding as you, then the hydraulic cartridge valve manufacturers will not make any progress. Only by stepping out of the comfort zone, finding customers with higher recognition than you, and using your sincerity to impress others, and the others are willing to enlighten you and take you to play, can hydraulic cartridge valve manufacturers elevate to a higher level. These are also what hydraulic cartridge valve manufacturer AAK has been doing in recent years. When hydraulic cartridge valve manufacturer AAK rises to a higher level, AAK needs to think carefully: how can they stand up in this circle? That, of course, is a continuous improvement in our own manufacturing quality. Hydraulic cartridge valve manufacturer AAK has gained recognition and guaranteed manufacturing quality. We still respect every customer who values excellence. AAK HYDRAULIC CARTRIDGE VALVES (781) 2024-03-03 https://www.aakindustry.com/info , -detail/hydraulic-cartridge-valve- manufacturer , s-aak781

Leo from Germany, who had been successful in the purchase of hydraulic valves, recently lost confidence in an order for hydraulic relief valves. During the test phase, when the pressure of the hydraulic relief valve sample is below 250bar, the system operates normally. Once it exceeds 250bar, the hydraulic relief valve will leak oil and the pressure will be unstable. After several debugging by their professional technicians, the oil will still leak when the pressure is high. After disassembling the hydraulic relief valves, no abnormality was found, but the O-ring was slightly scratched or the position was slightly offset, which may be the cause of oil leakage. The original hydraulic pressure relief valve manufacturer said that the O-ring material is synthetic rubber with the best anti-aging and oil resistance. It is the most suitable medium for this working condition. The assembly is also completed by 5 years of skilled workers. More new samples of hydraulic relief valves were tested, but they still leaks when the pressure is high. Leo believes that the O-ring seal of the hydraulic relief valve is improperly assembled, so it is urgent to find a reliable hydraulic relief valve manufacturer to re-produce it, otherwise there is a risk of shipping by air. Leo contacted more than 10 factories in 3 days, but none of them guaranteed that the sealing ring will be 100% free of displacement and scratches after assembly. The customer has been pushing for the progress of the approval samples, but Leo hasn't even determined the manufacturer. How can he take it easy? Leo started to look for new hydraulic relief valve manufacturers on Google, and noticed AAK hydraulic valve. He left a message to us: how should the synthetic rubber O-ring be assembled to make sure that there is no displacement or scratch? At the same time, it needs to make sure that when the pressure is above 250bar, the hydraulic relief valve does not leak oil, and the pressure is still stable. I told him that the disadvantage of the synthetic rubber sealing ring is that it is easy to deform under strong force, and not installed in place. As soon as the pressure is high, it will leak oil. Leo immediately sent the drawing of the hydraulic relief valve to AAK to make samples. Because we have the existing procedures for this hydraulic relief valve, 7 days later, the samples of the hydraulic relief valve were sent. 2 weeks later, Leo told me that AAK hydraulic relief valve had no oil leakage when it was pressurized to 300bar and tested continuously for 3 days. Most of hydraulic relief valve manufacturers install the sealing ring by directly pressing it with clamps. AAK suffered similar complaints 5 years ago. We have been skilled in and improved the installation process of O-ring 3 years ago. Apply lubricant to the long shaft of the valve first to ensure that the O- ring slides without resistance. When passes through the external thread, we will use the metal guide sleeve to guide it into the O-ring groove instead of forcing it in. After the O-ring is put into the groove and the O-ring is restored to 100%, check the gap to ensure that there is no displacement or scratch, and then install it into the valve body. When it is installed in the valve body, it should also be coated with lubricant to rotate and insert slowly, and the O-ring will not be affected. Yesterday, Leo sent a photo of him in the bar and told me that this was the most relaxing time in the past month for him. AAK hydraulic relief valve, O-ring is assembled with unique skills, no oil leakage, you can also have a small try! https://www.aakindustry.com/info-detai , l/hydraulic-relief-valve-aak271

Manator is from Indonesia and has been engaged in the procurement of hydraulic components for 2 years. At the beginning of last year, the hydraulic power unit they sold for deep-sea oil drilling was complained of as abnormal by customers 6 months later. The root cause is severe corrosion on the surface of the hydraulic cartridge valve in the hydraulic system, leading to dysfunction of the hydraulic cartridge valve. Manator was very confused because the valves sold to other markets from the same batch production has no complaint for over 1 year. The original hydraulic cartridge valve manufacturer stated that the corrosion in deep sea is severe, and the only solution is to replace the corrosive valves with new ones, and the service life can be only guaranteed for 6 months or less. The 6-month frequency of after-sales service not only results in high costs but also dissatisfaction from customers. The boss requested him to purchase hydraulic cartridge valves with a service life of more than 12 months to replace those corroded hydraulic cartridge valves. After sourcing for 1 week, but still without any results, the customer pushed for after-sales solutions several times, Manator was in a hurry. Manator left a message on AAK hydraulic cartridge valve website: Is the service life of AAK hydraulic cartridge valves guaranteed to be more than 1 year in deep-sea environments? I did not directly answer his question, but only sent him a case of a customized hydraulic flow control valve for a Brazilian customer: "AAK hydraulic flow control valves were still normal after being used for 15 months near the sea, while that of the peers corroded after 10 months.” Manator requested me to sample the hydraulic cartridge valves based on his drawings, and requested me to finish it as soon as possible to replace the hydraulic cartridge valves complained by customers. 45 days later, AAK sent out 40 hydraulic cartridge valves. After Manator received samples of AAK hydraulic cartridge valves, he just told us: AAK hydraulic cartridge valves can be used in their power unit, and their functions are consistent. Then, he didn't reply to my follow-up email. Last week, Manator sent an email with a repeat order for 200 hydraulic cartridge valves, informing us that his customer is very satisfied with this after-sales service. After replacing with AAK hydraulic cartridge valves, a year has passed and the hydraulic cartridge valves have no corrosion or abnormal function. They only trust AAK for hydraulic cartridge valves used in marine conditions in the future. The key of this hydraulic cartridge valve is its corrosion resistance, which is not difficult for AAK. 1. The selection of materials for hydraulic cartridge valves, with the valve body made of 3Cr3Mo3W2V hot working die steel, has a corrosion resistance of over 30% better than other steels. Although the material cost is over 30%, it is still the preferred material for AAK. 2. The surface treatment of the material adopts a zinc nickel alloy coating, and the coating thickness is controlled between 10-15μm. Compared to conventional zinc coatings, the corrosion resistance is more than 3 times higher. 3. AAK has a SH-90 salt spray testing machine for anti-corrosion testing of materials, which tests the valve body according to the GB/T2423.17 testing standard. Ensure that the anti-corrosion of any surface of the valve body meets the standard, and also ensure that there is no red rust after a neutral salt spray test for more than 1,500 hours. AAK hydraulic cartridge valve, is safe to use in the ocean, you can also give it a try!

Giacomo from Italy, an old customer of AAK, has been purchasing hydraulic cartridge valves smoothly in recent years. At the beginning of last year, he told me privately that he was a little annoyed recently. The hydraulic needle valves he purchased at the beginning of last year was not corrosion-resistant enough, resulting in a claim for their equipment, the four column hydraulic press. The boss has criticized him 3 times. This hydraulic press is used in a chemical plant. After a few months, the system pressure is abnormal. After disassembling the hydraulic needle valve, it was found that the valve body was severely corroded, and the wear was even more serious. The customer requests to replace the hydraulic needle valves immediately and compensate for the delay cost. The original manufacturer is also willing to replace the hydraulic needle valves, but he can only ensure the corrosion resistance for 6 months. Moreover, this batch of hydraulic needle valves is non-standard, and it takes 2 months to reproduce, so Giacomo is not in a good mood because the hydraulic needle valve manufacturer can not solve the problem completely. I gave our engineers the drawings and working conditions of this hydraulic needle valve. Coincidentally, this hydraulic needle valve is similar to the one ordered by a Dutch customer just 1 month ago, they are both a component of chemical hydraulic equipment. The only change needed is the size of the throttle port. The next day, I replied to Giacomo that AAK would send 40 hydraulic needle valves in 2 weeks to solve the urgent needs. Last week, Giacomo sent an e-mail to inform us that AAK hydraulic needle valves had been used, and the equipment had operated for 9 months without any abnormality. The hydraulic needle valves had no corrosion. The customer was very satisfied and his boss was even more satisfied that they had saved a sum of work delay costs. Giacomo admires that AAK hydraulic needle valves are not only delivered 4 times faster than the original manufacturer, but also has a service life of more than 2 times. Giacomo also told me that because of his performance of solving problems quickly this time, the boss also looked at him differently, paid more and more attention to him, and his good mood came back. AAK hydraulic needle valve has 3 advantages in the chemical industry, and the second manufacturer can not be found in Ningbo. 1. Hastelloy steel imported from the United States, as the preferred material for the valve body of hydraulic needle valves, is suitable for most corrosive media, with super corrosion resistance and wear resistance. 2. AAK hydraulic valve has a large amount of data storage and many existing programs. With UG/SOLIDWORK software, the process data of hydraulic needle valves can be configured in 2 hours, which is 3-6 times faster than that of other hydraulic valve manufacturers. AAK is equipped with Swiss advanced machine tools and its own modified fixtures, which not only has fast production speed, but also avoids human errors. 3. The customer selects AAK hydraulic needle valves for their chemical equipment, and has supplied 2 world top 500 chemical enterprises. AAK hydraulic needle valve, the delivery is 4 times faster than peers, but its service life is more than 2 times. You can also give it a try! https://www.aakindustry.com/info-detai , l/hydraulic-needle-valves-aak270

My friend recommended me to read a book. The title of the book is “courage to be hated”. It is said that it has dominated the first place in the sales list of Japanese books for 300 consecutive days. It's a set of great life philosophy: I have courage, so I'm not afraid of being hated. After reading it, I repeated it for a while. It's very interesting. Being hated may not be necessarily a bad thing. I was wondering, what would happen if a hydraulic valve manufacturer was also hated by its peers? Some people say that being hated by others may also be a fortune. It is a very interesting point of view.   Last month, an Indian hydraulic valve customer privately said that a very strong hydraulic valve manufacturer in Ningbo hated AAK hydraulic valves. I was a little confused at that time. After reading the book "the courage to be hated", I was a little relieved. I think the other way around. A strong hydraulic valve peer especially hates AAK hydraulic valve, which actually sends a signal to AAK hydraulic valve. AAK must have something that he doesn't have, but he wants something. Therefore, I would like to thank this strong hydraulic valve peer. It is the peer's disgusting expression that helps AAK identify its own advantages. In fact, this peer also makes endorsement for AAK at the customer. Think so, why not be relieved? I think human nature is usually like this, because he has done something I can't do, he has something I can't have, and this kind of thing also damages my sense of security, so I hate him. If others hate me, I need to ask myself, why do others hate me? This question seems very difficult to answer because you don't know the starting point of others. If you send it to yourself, you may find the answer quickly. For example, why do I hate someone? For example, a person always likes to show off his wealth, always exaggerates, always flatters the leaders, and so on. These are all things I secretly want to have, but they are difficult to do. Because of this, my sense of security has been damaged, so I hate him.   In AAK hydraulic valve, what have we done to annoy our peers?   1. AAK hydraulic valve dares to announce the chaos in the hydraulic valve industry, pointing out the problems existing in the hydraulic valve industry and the pain points existing in the hydraulic valve industry. 2. AAK hydraulic valve adheres to the manufacturing quality, focuses on the process innovation of hydraulic valves, and pays attention to the research and development of new types, new functions and high service life of hydraulic valves. 3. AAK hydraulic valve is promoted on the Internet every day. It says something that peers have not said or can not say every day, and also helps customers solve the difficult problems encountered on hydraulic valves. In any case, whether the peers hate it or like it, AAK hydraulic valve only adheres to the right path, and then works hard, occasionally looking up at the sky. I know that those who are good at chess have no good skills. Take a road few people take and do something difficult and right. All the difficult things will become simpler, and the simple things will become more and more difficult. The difficult road is never crowded. AAK hydraulic valve is always walking to the customers who are fastidious. https://www.aakindustry.com/inf , o-detail/hydraulic-valve-manufacturer-aak269

Jone is a hydraulic customer from Canada. In recent years, his purchasing of hydraulic valves has been very smooth. However, an urgent order of 200 hydraulic valve blocks in his hand recently gave him a headache. The customer reported that 70% of the hydraulic valve blocks had large coaxiality deviation between the hole and the outer circle, which damaged the thread of the cartridge valve during assembly. The customer requested him to replenish half of the hydraulic valve blocks within 15 days, but the original manufacturer of the hydraulic valve blocks had to surrender. Although the lathe processing parameters were adjusted, and even the hydraulic valve block materials were changed, the hole position drift could not be solved, that is, the coaxiality deviation between the hole and the outer circle was large. Jone consulted more than 20 hydraulic valve block manufacturers before and after. Most of the manufacturers said that they could not completely avoid the drift generated during the drilling process of the hydraulic valve blocks, which could only be controlled between 1-2‰, but the customer's requirements could not be higher than 1‰. A week had passed, and Jone was still unable to give a plan for the aftermath, and his boss was not satisfied. Jone, introduced by his friend Blake, who is also my old customer, sent me an email. According to his hydraulic valve block drawings and the layout of the holes, I told him that during deep hole drilling, there would be symmetry errors between the two cutting edges of the drill bit, or the sharpness of the drill bit would be inconsistent after wear, which would cause the hole position to drift. Under normal circumstances, for example, it is difficult to control the 100mm drift value at 0.1mm, that is, the error of 1 ‰. There are really not many hydraulic valve block manufacturers who can meet his customer’s requirement standard. Even if the hole is reamed after drilling, the hole position drift caused by drilling cannot be corrected. However, 3 years ago, AAK did not adopt this traditional processing method and matured the new processing technology. Jone asked me to help replenish the goods directly. The customer had no time to wait for the samples. Three weeks later, AAK sent a replenishment of 100 hydraulic valve blocks and told Jone not to worry about the problem of hole drift that the original manufacturer could not solve. AAK hydraulic valve block is processed by using the outer circle to adapt to the inner hole, which is not only less than 1 ‰ of the error, but also has no deviation in the coaxiality between the hole and the outer circle. Here is how our workshop processes it: (1)Blanking, with a total length allowance of 2mm. (2)Lathing the left end face to be shiny, rough lathing the outer circle to be φ 35.5mm. (3)Clamp the rough turned excircle at the left end and finish turning the right end face to ensure a total length of 80 ± 0.05 mm. Drill and ream φ 4.9 ± 0.05 mm through hole. (4)Deburr the holes at both ends, and process φ 4.9 ± 0.05 mm holes at the two sharp tips, fine turning φ 34.9 mm outer circle. (5)With φ 34.9 mm excircle as the benchmark to process other dimensions. With φ 4.9 ± 0.05 mm holes machined first, and then φ 4.9 ± 0.05 mm hole is used as the benchmark to process the remaining dimensions of the hydraulic valve block so that the drift error in the processing of φ4.9 ± 0.05 mm hole was corrected in the subsequent processing, and the coaxiality between the hole and the outer circle of the hydraulic valve block was also guaranteed. AAK hydraulic valve block valve hole, no hole drift, high coaxiality precision, you can also have a small try! https://www.aakindustry.com/info-detai , l/hydraulic-valve-blocks-aak268

Abel from Dubai, who has been purchasing hydraulic cartridge valves in China for 3 years, has been running smoothly, but he encountered trouble with a hydraulic solenoid cartridge valve that is benchmarking against HydraForce SV12-22. At the beginning of this year, their hydraulic manifold used in logistics vehicles required the SV12-22 hydraulic solenoid cartridge valve. Abel purchased 100 pcs of hydraulic cartridge valves from the original hydraulic cartridge valve supplier in China. 1 month later, their customer complained about the leakage of the hydraulic cartridge valve, and the engineer found that the valve cage of the hydraulic cartridge valve was significantly worn and the valve spool was corroded. The original manufacturer shifted the blame and the brake oil medium used did not meet the standard. Alternatively, materials with a hardness of HRC70 or higher may be used, but the machining accuracy cannot be guaranteed. Abel was helpless and anxious. Abel found AAK. After communication, it was learned that he was in trouble while purchasing the SV12-22 hydraulic solenoid cartridge valve. I told him that the brake oil medium is used in the SV12-22 hydraulic solenoid cartridge valve, even if HydraForce original valve will also have potential failures, and it is necessary to improve the hardness of the material and perform anti- corrosion treatment. Especially in the precision machining process, most hydraulic cartridge valve manufacturers cannot control the stability of accuracy very well. I suggested making samples for Abel directly. After 45 days, AAK sent 30 pcs of improved SV12-22 hydraulic solenoid cartridge valve samples to resolve Abel's customer complaint first. 3 months later, Abel informed us via email that no leakage was found on the AAK SV12-22 hydraulic solenoid cartridge valve samples, and they wanted to re-peat the order for 300 pcs. I think that the accuracy of AAK SV12-22 hydraulic solenoid cartridge valve has received his recognition and reorder. The improved SV12-22 hydraulic solenoid cartridge valve adopts the American SUNNEN honing machine in the valve cage precision machining process, with its SAC size automatic control system. It does not automatically stop until the honing reaches the accuracy set by the system. The upgraded filtration system eliminates impurities in honing oil. Especially for diamond honing stones, processing materials with HRC70 or higher is a perfect match, not only stable but also efficient. Our technicians perform the following operations: first, set the correct machining program on the computer system of the equipment, and then install the rough machined valve cage into the equipment. After starting the program, the equipment automatically completes honing. With the escort of this equipment, the precision of the processed hydraulic cartridge valve cage is stable within 2μm, the roundness can reach 1.5μm. The roughness can reach Ra0.1. But most hydraulic cartridge valve manufacturers do not have such high- end honing equipment, and there are few equipped with diamond honing stones, which is the key to the inability to process high hardness valve cages. AAK SV12-22 hydraulic solenoid cartridge valve is processed with 3 advantages of equipment, and 2 methods of operation. You can give it a try!

Friedlich, from Wirth company in Germany, sold the drawworks of oil drilling rigs to the Middle East at the beginning of last year. Six months later, the customer complained that the disc brake controlled by the hydraulic cylinder of the drawworks was weak, resulting in equipment shutdown. The reason was that the hydraulic flow control valve in the hydraulic system was stuck. Friedlich wondered that the same batch of drilling rigs and drawworks had been sold to Canada, Central Europe and other markets for almost 1 year, and there was no such abnormality. The original manufacturer of the hydraulic flow control valves is not sure why it is stuck for half a year, but is willing to offer 30 hydraulic flow control valves for replacement and send them to the Middle East. Friedlich was very worried about such solution without knowing the cause of the stuck valve spool. Sure enough, a batch of hydraulic flow control valves had to be replaced 6 months later. This frequent after-sales service not only costs a lot, but also makes the customer dissatisfied. The boss asked Friedlich to purchase new hydraulic flow control valves with high temperature resistance and durability of more than 1 year as soon as possible to replace the current ones. Friedlich found AAK on the Internet and left a message to us: why does the same hydraulic flow control valves have twice the service life difference in different working scenarios? I was puzzled when I saw this message. I learned the above story after communication. Our engineer checked the drawing of hydraulic flow control valve sent by Friedlich, and there was no problem from a technical point of view. The probability is that the high temperature in the Middle East and the high-frequency operation of the drawworks will lead to high hydraulic oil temperature and thermal deformation of the valve sleeve, which will reduce the matching clearance between the valve sleeve and the valve spool, affecting the movement of the valve spool until the valve spool is stuck. Friedlich learned that when the drawworks work, the oil temperature is above 70 ℃, while the oil temperature of the normal hydraulic system is 30 ℃ -50 ℃. Friedlich seemed to agree with our analysis and asked AAK to send samples of hydraulic flow control valves as soon as possible. AAK engineers know that the core of this hydraulic flow control valve lies in the material selection of the valve sleeve. It depends on the job of our full- time material engineers. After 2 months' efforts, 6 kinds of materials were tested, and a special hot work die steel was determined as the valve sleeve for the hydraulic flow control valve. Its heat fatigue resistance and toughness fully adapt to high-temperature hydraulic oil, and the hardness and wear resistance of the material can also fully withstand the wear of more than 1 year. Eight months after the samples of AAK hydraulic flow control valves were sent out, Friedlich informed us that there was no complaint of valve spool jamming when AAK hydraulic flow control valves were used. I told him that within 12 months, if there was a complaint of valve spool jamming, we would refund all expenses. AAK has a full-time Material Engineer in the selection of materials. He connects with the materials research institute and university laboratories to master new materials at the first time. He is specially responsible for screening, comparison and testing, and matching suitable materials according to the working conditions of the hydraulic valves, instead of general materials in the market., In the selection of raw materials and spare parts, it is targeted from the requirements of working conditions and never goes with the market trend. Especially in the customization of hydraulic valves with high requirements, there are unique methods and cases. AAK hydraulic flow control valve, under high temperature, free of worry in 12 months, you can also have a small try! https://www.aakindustry.com/info-detai , l/hydraulic-flow-control-valve-aak267

A few days ago, a colleague complained that Guru, an Indian customer, was not trustworthy. He promised AAK as their preferred hydraulic cartridge valve supplier. Half a year later, he sent samples of the hydraulic cartridge valves shipped by AAK to other hydraulic cartridge valve manufacturers for inquiry. After communication, I learned that Guru had a cartridge valve that had a problem before, AAK helped him solve it, and Guru made a commitment to this colleague.   Whether in work or life, there are too many unsatisfactory things. For example, the promised cooperation has not been implemented; the person who promised to see you did not arrive; the phone promised to you was not called etc.   We should be happy when we listen to the promise from others, but don't take it too seriously. The advantage of this is that you are grateful for it if it is done; it doesn't matter if it is not done. You don't care too much about it, and naturally you won't be too disappointed to hate others.   In terms of concrete implementation, we must accept changes and have a philosophical attitude. Because time is changing, the situation is changing, the environment is changing, and the mood is changing, many variable influences will affect the original commitment. If you can accept the change, you can take good words and promises lightly and understand the difficulties of others. Besides, how should we expect the favors from others, just because they agreed?   I remember that many years ago, we went to Shanghai for training, and we met many local hydraulic valve colleagues in Shanghai, as well as fellow villagers and alumni. We were very happy together. There is an alumnus A, who is the leader of a unit and is equipped with a special car. He sent the car to pick up and drop off wherever we go, which was naturally much more convenient. Everyone thanked him one after another, and he promised: when you come to Shanghai in the future, you must let me know, I will send a car to pick you up.   Soon after, we went to Shanghai for refresher training. The engineer Zhang from the same training group wanted to go to the university in the suburbs to see his daughter. There was no direct bus there. Someone has an idea: let alumni A send a car to drive you there! Engineer Zhang called Alumni A without thinking about it. Alumni A told him that he was in Hong Kong. He was not there. It was not convenient to ask the company to send a car. Engineer Zhang was very angry. He told everyone that alumnus A was a man with empty talk: "Don't tell me if you can't do it".   I advised him: Alumni A said this to everyone, not to you only. Many people didn't take it to heart, just listened to it. Because we don't have much friendship with alumni A, what is the reason for them to pick us up? And alumnus A is also telling the truth. He is not in the company and still occupies the public car. It is really inappropriate. After all, it is the company's car, not his private car. Why should we make trouble for others?   In fact, many times, a word from others makes us have thoughts we should not have, and makes us lose self-knowledge. We should trust the goodwill of others, but we should not take it too seriously.   We should appreciate the kindness expressed by others, but we don't really have to accept the kindness of others. To face life with a grateful heart will always be full of positive energy. A person full of positive energy has the ability to turn others' goodwill into reality.   A person who takes the kindness of others for granted is not qualified to accept the kindness, because you lack a little virtue, and disappointment is inevitable and self-seeking. The same is true for us manufacturing hydraulic valves. If there is only price, no value; only profit, no quality, that virtue is also lacking.   AAK Hydraulic Valve, makes business with a positive mind, and makes friends with kindness. https://www.aakindustry.com/info- , detail/cartridge-valve-manufacturers-aak483
