Iscen from Türkiye left a message on the website of the hydraulic cartridge valve manufacturer AAK: What if the valve holes of the hydraulic cartridge valve has burrs? After communication, it was learned that Iscen is a wholesaler of hydraulic cartridge valves, and has been purchasing from hydraulic cartridge valve manufacturers in China for 3 years. They designed a hydraulic cartridge valve themselves, and for every batch of production from the original manufacturer, there were always several customer complaints about burrs in the valve holes of the hydraulic cartridge valves. Although the defective quantity was not large, Iscen was still worried about losing the customer. According to the picture of the hydraulic cartridge valve sent by Iscen, one of the valve holes has a very small diameter, improper drilling can result in residual burrs and difficulty in cleaning. In the early days, hydraulic cartridge valve manufacturer AAK also encountered this type of problem. Our equipment engineer spent more than half a year modifying the equipment based on the Jinlida Drilling Center as a specialized equipment for processing small aperture valve holes. I have a short video I took for an American client a few months ago. At that time, we processed small aperture valve holes using optimized Jinlida drilling center. The tools and drill bits used were customized from Germany and washed with double water pipes. The optimized drilling equipment has 3 advantages: 1.Fast processing: With one clamping process, from cutting, drilling to tapping, the machining is completed in one go, which not only has high efficiency but also avoids human errors. 2.No burrs: The drill bit is magnetic and can automatically remove cutting burrs. 3.High precision: The drilling center adopts a servo control system, which timely controls the position and motion trajectory of the cutting tools. The automatic tool replacement system reduces errors in manual operation and provides accuracy assurance. AAK hydraulic cartridge valve, no burrs or residue, you can also give it a try!

Erop comes from Russia, and started purchasing hydraulic cartridge valves from Ningbo 2 years ago. In the second half of last year, they customized a hydraulic cartridge valve for use in their power unit equipment. After debugging, it was found that the equipment has 3 disadvantages: vibration, high impact, and high energy consumption. Their engineer optimized the hydraulic system, but the customized hydraulic cartridge valve did not work well. After 3 times of revision, the sample still failed to match the equipment requirements, which made Erop very upset. Erop found AAK in B2B, browsed AAK website for more than 5 minutes, and left a message: Can the AAK hydraulic cartridge valve solve the problems of vibration, high impact, and high energy consumption in the hydraulic power unit? This question is too big. It is hard to determine if it can be solved solely by replacing hydraulic cartridge valves. After communication, it was learned that his customized hydraulic cartridge valve was unable to upgrade their equipment. Based on the schematic diagram of the power unit system provided by Erop and the anatomical diagram of the original hydraulic cartridge valve manufacturer, AAK engineers have determined that the valve spool of the original hydraulic cartridge valve is under unbalanced force and is a hidden danger, AAK can make samples to solve the hidden dangers of equipment vibration and impact, but not very certain to solve the energy consumption problem. Erop may not have a better choice, and asked AAK to make samples after a week later. After 45 days, AAK sent out 10 samples of hydraulic cartridge valves. 4 weeks later, Erop informed us that the equipment trial run was successful. Their engineers were very satisfied with the 2 advantages of AAK hydraulic cartridge valves (no vibration, low impact). Their hydraulic power unit energy consumption also decreased by more than 10%. Compared to similar devices in the market, their equipment highlighted 3 major selling points (low vibration, low impact, and energy consumption reduction). The concept of AAK hydraulic cartridge valve is that the original valve spool is in an open state and cannot be closed, which is the root cause of impact and vibration. If the valve spool is closed or opened, a large amount of oil is required, which also leads to high energy consumption. We made clever moves around the valve spool. The force area on both sides of the AAK hydraulic cartridge valve spool is equal and the force is balanced. The valve spool is not affected by pressure, shortening the opening and closing time, and the movement state of the valve spool is easy to adjust and control, reducing impact and vibration, and reducing noise. 1. The valve spool is arranged in the valve chamber of the valve sleeve and can slide. There are axial and radial main oil ports in the front of the valve chamber, and the rear of the valve chamber is separated into a pilot controlled opening chamber and a pilot controlled closing chamber by a convex plate located on the outer side of the rear end of the valve spool. 2. The spring is installed in the spring installation chamber at the rear end of the valve spool, and there is a ring shaped extension at the rear end of the boss, and the outer diameter is smaller than the inner diameter of the valve chamber. The rear end of the valve chamber is fixed with a guide sleeve that allows the ring shaped extension to slide through it. 3. The valve chamber between the boss and the guide sleeve forms a pilot controlled closing chamber. AAK hydraulic cartridge valve, 2 advantages, no vibration, low impact, you can also give it a try!

Consuelo is from Spain, and has purchased hydraulic cartridge valves from AAK 8 times. At the beginning of this year, she inquired about cartridge solenoid valves, and a week later, she reported that the price of AAK solenoid valves was higher than other hydraulic cartridge valve manufacturers in China. Therefore, she did not purchase the solenoid valves from AAK, and I did not ask too much because working with her on hydraulic cartridge valves was also quite good. Last month, she suddenly asked me, 'Is the price of the cartridge solenoid valve that AAK quoted last time still valid?'? After communication, I learned that she encountered difficulties in purchasing cartridge solenoid valves from other hydraulic cartridge valve manufacturers in China. At the beginning of this year, they developed hydraulic manifolds that required the use of cartridge solenoid valve equivalent to HydraForce standard part SV08-20. Consuelo chose a hydraulic cartridge solenoid valve manufacturer in Ningbo to place the order. But now their prototype has been complained by customers that the magnetic sleeve of the cartridge solenoid valve is not securely welded, and some solenoid valve magnetic sleeves have friction with the armature, causing hidden dangers. Consuelo realized that this hydraulic cartridge valve manufacturer was unreliable and came to me. She asked us to ship 100 pcs of cartridge solenoid valves within 40 days, and specially emphasized the welding of the magnetic sleeve of the cartridge solenoid valve to avoid the hidden dangers of friction. I told her, what kind of experience you had with purchasing hydraulic cartridge valves from AAK before, and the same goes for purchasing cartridge solenoid valves from AAK, so there's no need to worry about purchasing cartridge solenoid valves from AAK. I specially made a video for her to understand the difference between AAK and most hydraulic cartridge solenoid valve manufacturers in China. AAK adopts Planck laser welding machine and adopts brazing welding process. It brings 2 benefits to us: firm welding, small deformation, ensuring stable processing accuracy of the magnetic sleeve, and high production efficiency. Most cartridge solenoid valve manufacturers outsource the processing of magnetic sleeves, and generally use argon arc welding technology. The hidden danger is that there is large deformation during welding, and the dimensional accuracy of the magnetic sleeve during processing is not stable, which can easily cause hysteresis of the solenoid valve. At the same time, the welding fastness is also unstable, which can easily cause fracture at the welding point of the magnetic sleeve of the solenoid valve. The manufacturer chosen by Consuelo adopts this process, which not only has poor production efficiency but also brings hidden dangers to customers. AAK cartridge solenoid valve, a new process, brings you 2 major benefits, you can also try it out!

I've been working on hydraulic valves for 13 years, but I never say I've focused on hydraulic valves for 13 years. 13 years of hydraulic valve career, has been adhering to. I think no matter what you do, 10 years is a cycle, because only 10 years of persistence can make some small achievements, but they are only small achievements, which can't catch up with success. There must be compound interest in long-termism, but it does not mean that we should do it mechanically in the 10 years and then wait for the arrival of the cycle moment of the 10 years. It's impossible for me to stick to the industry for 10 years if without orders coming one by one in the daily working time, absolutely not possible. Therefore, long-termism is to produce hydraulic valve orders, while making hydraulic valve innovation at the same time. After 10 years of deliberate learning, pondering and imitating the major brands of international first-line hydraulic valves, we can make some small achievements at the time of the arrival of 10 years. AAK hydraulic valve is not a big brand. I never imitate the words of "lyrical romance" of big brands. Instead, I insist on what benefits AAK hydraulic valve can bring to users, what problems have been solved and what pain points have been solved, that is, the difference of AAK hydraulic valve function and performance from its peers. It has been 13 years since I started my business. 70% of the hydraulic valve customers come from the network and 30% of the customers come from the introduction of these 70% customers. My idea is like this: 1. Never burn money to advertise hydraulic valves. Almost all of them are free promotion at the cost of a lot of time and energy. There seems to be no holiday in a year. I have to work for about 12 hours every day. Because I'm stupid, I can only do a little every day, but I never stop. 2. Focus on the cartridge hydraulic valves, a single large category, which has been used in the hydraulic system in the fields of engineering machinery, agricultural machinery, field exploration and aviation flight. It is positioned for high-end customers who pay attention to quality and never produce the market common quality. 3. For the raw materials and semi-finished products, process and technology, production equipment and production line control of hydraulic valves, I dare not say I am proficient in these 4 parts, but at least at the level of assistant engineer. This is the basic skill and hard work of doing content. 4. Like to output the content of hydraulic valves, write the content that customers want to see and will see, so as to attract real hydraulic valve customers and help customers solve problems, even if they give customers a "so it is". 5. Mindfulness to be a man and to do things. I never believe in the concept of "treat the company as your family", which either cheat employees or cheat yourself. In my understanding, mindfulness is not to cheat, or make small movements under the table. It is not difficult to improve the quality of hydraulic valves, and it is difficult for me to understand why some hydraulic valve manufacturers like producing market goods. As long as the cost of raw materials and semi-finished products is increased by 5 ~ 10%, the quality of hydraulic valves can be greatly improved. I don't know, why can't these bosses change? AAK hydraulic valve adheres to the top 1% of the subdivided market. At the same time, it aims at the global first-line hydraulic valve brands in terms of quality, first benchmarking them, and then surpassing them. With 13 years of long-termism and being the ODM factory of the global top 10 hydraulic valve brands for many years, AAK has been able to surpass the international first-line brands in terms of export quality and price. AAK hydraulic valve, never cheating or doing small movements under the table https://www.aakindustry.com/info-deta , il/hydraulic-valves-aak226

Jone is a hydraulic customer from the United States. His company has recently developed a hydraulic relief valve suitable for machines with high impact and high load. Because of the high requirements of working conditions, the steel used for the hydraulic relief valve has not been approved yet. They have been testing in the local hydraulic relief valve manufacturers in the United States for several weeks. Due to the high cost of proofing in the United States, they want to turn to Chinese hydraulic relief valve manufacturers for sampling and testing. Jone compared more than 10 hydraulic relief valve manufacturers and selected 3 to make samples. After receiving and testing the samples of hydraulic relief valves, none of them can meet the requirements of service conditions, and the test results are much worse than those of local manufacturers in the United States. Although these 3 hydraulic relief valve manufacturers changed the materials and improved the parameters, the toughness and plasticity of the steel still did not meet the working conditions, and Jone and his team were at a loss what to do. His friend Tom recommended him to contact AAK hydraulic valve for a try. Jone sent us an email with a try attitude. According to his hydraulic relief valve drawings and the working conditions with large impact force and high load, our engineers were not 100% sure, but were 90% sure, giving 2-3 weeks. Two weeks later, AAK successfully sent 6 hydraulic relief valve samples. On the 3rd day after Jone received the hydraulic relief valve samples, we received an email that the samples of hydraulic relief valve passed the performance test. AAK spent 2 weeks to try over 10 kinds of steels, and finally determined to replace 40Cr with 35CrMo steel. The high toughness and plasticity parameters of 35CrMo well match the working conditions of this hydraulic relief valve. At the same time, 35CrMo has high static strength, impact toughness and high fatigue limit, and the long-term working temperature can reach 500 ℃. Jone was surprised that the samples of more than 10 hydraulic relief valve manufacturers in China were not successful. Even if the local manufacturers in the United States spent 4 weeks but still failed, how can AAK succeed in 2 weeks one time? The reason why AAK hydraulic relief valves can do what the domestic factories in the United States failed to do, because: 1.AAK has full-time material engineer who is specially responsible for material screening, comparison, testing and docking with the materials research institute. 2.Good materials also need good processing. The heat treatment method adopted by AAK for 35CrMo alloy steel is 845 ℃ annealing, 860 ℃ quenching (oil quenching) and 200 ℃ low temperature tempering. After this special heat treatment, its hardness and wear resistance are increased by at least 50%. 3.AAK technical team has engineers from the global top 10 hydraulic valve industry. They have their own experience in material selection, production drawing design and production line quality control. AAK hydraulic relief valves, high load and high impact resistance, you can also have a small try! https://www.aakindustry.com/info-detai , l/hydraulic-relief-valves-aak225

This morning, I received the order of 2,000 hydraulic needle valves from Charlotte. At first, I thought she sent the email by mistake, because Charlotte had no cooperation with AAK, we just discussed the inquiry for her hydraulic needle valve with pressure resistance of 450bar for 3 times. It is the first time I met a hydraulic valve customer who placed a big order after 3 times of communication. I asked her directly why she gave AAK such a large quantity of hydraulic needle valves order in only the first cooperation. Charlotte said that this hydraulic needle valve was purchased from HAWE in Germany 3 years ago, because HAWE is the best manufacturer of high-pressure hydraulic valves in the world. Charlotte is from a hydraulic equipment company in Spain. Last month, their company tried to purchase this high-pressure hydraulic needle valve from Ningbo, which is the hometown of hydraulic valves in China. She has a hydraulic valve supplier who has cooperated for 5 years and has high mutual trust. Due to the special requirements and urgent delivery date of this hydraulic needle valve, the original hydraulic valve supplier was unable to bear it, so he suggested Charlotte contact AAK, and joked that if AAK could not complete this hydraulic needle valve, she should not waste more time in Ningbo, but go back to HAWE to purchase the high-pressure hydraulic needle valves. I received the drawings and working condition requirements from Charlotte. This customized hydraulic needle valve is applied to aviation equipment. The working condition pressure is required to reach 450bar. It is required to be delivered within 50 days. The quality needs to be comparable to that of HAWE in Germany. Just like Ningbo counterpart said, in Ningbo, there may not be a second manufacturer who is able to produce this high-pressure hydraulic needle valve except AAK hydraulic valve. Charlotte was curious about why the Ningbo counterparts recognized AAK high- pressure hydraulic needle valves so much, and AAK was also so confident in its own high-pressure hydraulic valves. What is the strength of AAK high-pressure hydraulic needle valves? Like horse racing, if you want to win the gold medal, then a good horse should be equipped with a good saddle and a good rider. What are the good horses, saddles and riders of AAK? If you need to meet the following 3 points at the same time, you may not be able to find a second hydraulic valve manufacturer in Ningbo to produce high-pressure hydraulic needle valves, except AAK hydraulic valve. 1. Good horses: AAK has high-precision machine tools imported from Switzerland, Mikron GF high-precision CNC machining center and GILDEMEISTER turn milling composite machining center. 2. Good saddles: AAK has full-time material engineers in material selection, who are specially responsible for screening, comparison, testing and docking with the Research Institute. According to the working conditions of the hydraulic valves, the suitable materials are matched pertinently, not to use the general materials in the market. 3. Good riders: special personnel shall be assigned to operate the special machine in key processes. Only technicians who have worked in the workshop for at least 5 years can take up the post. There are engineers from Shanghai factory of Germany HAWE, who have worked there for 11 years. They know all the production and processing technologies of HAWE factory back to front. They can fully benchmark HAWE factory in terms of material selection, process formulation, production line control, quality inspection and other processes. Charlotte can’t refuse the 3 unique advantages of AAK high-pressure valves and confirmed the PO in 2 days with AAK. A single flower does not make a spring. The improvement of products may not just due to market competition, but also the improvement of the level of the whole industry. AAK leads Ningbo hydraulic valve manufacturers to jointly face the high-pressure hydraulic needle valves. AAK high-pressure hydraulic needle valves are recognized as a leader in the industry by counterparts. Welcome to have a small try! https://www.aakindustry.com/info-detai , l/hydraulic-needle-valves-aak224

How can there be a worldview without observing the world? Whether it's the boss of a hydraulic manifold manufacturer or the management of a hydraulic manifold manufacturer, especially their children, the purpose of studying abroad is not to come back and find a job in the future. If the child of a hydraulic manifold manufacturer simply wants to find a job, there is no need to go abroad. It's better to stay in his hydraulic manifold manufacturer factory and gradually polish into a senior technician. For children of hydraulic manifold manufacturers, studying abroad is not for a diploma or educational background, but for their own career and future development as hydraulic manifold manufacturers. China is doing very well now. The Belt and Road Summit has attracted more than 140 countries (more than 70% of countries), more than 30 international organizations, held an international conference of 4000 elites, signed 711.1 billion yuan (97.2 billion dollars) of cooperation projects, and nearly 300 domestic and foreign entrepreneurs signed on-site contracts in 15 batches, covering 68 countries and regions. Perhaps only China has such a calling power for such a high-level international conference. So, the boss of a hydraulic manifold manufacturer should try to send their children out to study abroad and expand their horizons. If they don't go to see the world, how can they have a worldview? What major do children from hydraulic manifold manufacturers choose to study abroad? 1) International trade. 2) Business. 3) The technology, process, or design related to one's own hydraulic manifold manufacturer. Why not study other majors? 1) Future hydraulic manifold manufacturers will inevitably move towards Industry 4.0, using artificial intelligence equipment. Perhaps 20 years from now, hydraulic manifold manufacturers may no longer need workers in their workshops. 2) In the future where the staff size of hydraulic manifold manufacturers is increasingly shrinking, enterprise management has become simpler, and sales have become the top priority for factories. 3) Especially for a hydraulic manifold manufacturer, online marketing, dissemination, and sales are the only functions that affect the future. Of course, another important task for children to study abroad is to learn English well, especially their oral communication skills, which is difficult to achieve in a Chinese environment, such as learning mute English. Only by integrating into the local society can one master true spoken English. Children studying abroad have 3 major systems of knowledge besides their majors. 1. Choose more underlying disciplines such as mathematics, history, or philosophy, which can enable children from hydraulic manifold manufacturers to have the underlying logical thinking and reach the essence in 3 seconds. 2. Multiple choices in psychology, behavioral economics, and neuroscience are very helpful for the marketing of hydraulic manifold manufacturers, not only understanding what sales are, but also knowing why. 3. Multiple choices in Western classical music, painting, and comparison of Eastern and Western cultures, are helpful for communication between hydraulic manifold manufacturers and Western customers. It doesn't take time, it's still fun, who doesn't love it? I am a person with a background in engineering. After entering society, I have great limitations in thinking and cognition. I hold a scientific attitude towards everything, and often have a single minded mind. It is clearly out of sincerity, but in the end, things go against my wishes, which is really foolish. This foolishness may be due to low emotional intelligence. A low emotional intelligence makes a fool of oneself. Hydraulic manifold manufacturers, whether in business or enterprise, apart from focusing and focusing, the key elements for true success are not technology and craftsmanship, but the 3 major choice systems mentioned above. Never underestimate them. This is a matter of experience. At my age, I should be qualified to say a little bit. Emotional intelligence is not something that can be seen on the surface, such as being able to speak, be funny, or come up with things. Only in social practice can one gradually realize what true emotional intelligence is. Hydraulic manifold manufacturer AAK, a bit silly, but always hold onto the right mindset.

Christopher is from Italian hydraulic company Hydr-app S.p.a. and responsible for the procurement of Beijing office. At the beginning of last month, he wanted to purchase a batch of hydraulic flow control valves urgently from AAK, because they had a batch of hydraulic power units sold to Southeast Asia that needed to replace the hydraulic flow control valves. At the beginning of last year, considering the cost and supply, his boss purchased the hydraulic flow control valves from China, which were originally purchased from Brevini locally. At the beginning, AAK also participated in the sampling of hydraulic flow control valves, but was cancelled because the quotation of AAK was more than 25% higher than that of other hydraulic valve manufacturers. Half a year later, they were complained several times that the hydraulic flow control valve leakage led to the unstable pressure of the hydraulic power unit. The original manufacturer replaced some hydraulic flow control valves, but 6 months later, similar complaints happened again, that is, the stability of these hydraulic flow control valves was only 6 months. Christopher found that the AAK hydraulic flow control valve samples have been normal for more than 1 year, which is as stable as the Brevini hydraulic flow control valves they purchased before. He persuaded the boss to buy from AAK. Although the price was more than 25% higher than other hydraulic valve manufacturers, but it was about 30% cheaper than that of Italy Brevini. More interestingly, the stability of AAK hydraulic flow control valves were not only more than twice that of its peers, but also benchmarked Brevini. Christopher wants to find out why the hydraulic flow control valves of every factory samples are qualified at the beginning. Six months later, except AAK, all other hydraulic flow control valves will leak and affect the stability. The leakage of hydraulic flow control valves after half a year is mostly due to the wear of parts, that is, the unstable surface hardness of materials during heat treatment. Most manufacturers adopt conventional heat treatment, which has advantages in processing cost. How does AAK do it? 1. AAK hydraulic valve has its own heat treatment plant, which can adopt different heat treatment methods in quenching, carburizing and nitriding according to different contents of steel. AAK can achieve the aging temperature of 420 degrees, heat preservation of more than 10H, and can also obtain the material hardness of 65HRC. 2. The core component materials of AAK hydraulic flow control valves use the industry's most advanced EFD Induction Sinac heating power supply for induction heat treatment, with less oxide scale and small deformation. The workpiece is quenched and locally heated accurately to make the surface hardness of each processing element consistent. 3. In the later stage, AAK test the hardness of each part of the hydraulic flow control valves point-to-point. SonoDur3, a Rockwell hardness tester imported from Germany, is used to perform nondestructive testing efficiently and accurately. The Italian customer said that the stability of AAK hydraulic flow control valves was benchmarked with Brevini. You can also give it a try! https://www.aakindustry.com/info-detai , l/hydraulic-flow-control-valves-aak223

This morning, Mason sent an email asking about the production time of 2,000 hydraulic relief valves, which surprised me. Usually, he just places small trial orders of hydraulic relief valves. He is going to place a large order this time. Mason is a purchaser of BRACEBRIDGE company in Canada. We have known each other for 2 years. After communication, it was learned that a batch of their hydraulic pipe laying rigs had been complained about the frequent leakage in the hydraulic pump since the previous year. The after-sales engineer found that the cavitation was caused by the oil passing through the hydraulic relief valves for a long time, resulting in the pressure loss of the hydraulic cylinder. Mason contacted the original manufacturer of the hydraulic pressure relief valves to find a solution. The manufacturer advised that such a working environment can only replace the hydraulic relief valves with cavitation. The trouble is that the same problem happened again half a year later. The customer was very unhappy with this frequent after-sales, and the boss asked Mason to replace the manufacturer of hydraulic relief valves. Mason told his boss that there is no reliable manufacturer of hydraulic relief valves to replace the present one. For the sake of safety, AAK hydraulic relief valves should be selected. Because there was equipment installed with AAK hydraulic relief valves when testing samples at the beginning. Now 1 year later, there is still no cavitation on AAK hydraulic relief valves. But the price of AAK hydraulic relief valve was 17% higher than that of other manufacturers and was not selected. The boss rejected again and asked Mason to find a new manufacturer of hydraulic relief valves. During the continuous screening process, Mason selected 3 hydraulic relief valve manufacturers to test samples. Basically, after half an year, these hydraulic relief valve samples successively had similar faults. Mason was at a loss what to do. He once again suggested to his boss to purchase AAK hydraulic relief valves. After comparing so many hydraulic relief valve manufacturers, none of their samples can be used for more than 1 year under this working condition. In this way, the hydraulic relief valves need to be replaced every 6 months for after-sales. Not only the after-sales cost is high, but the customer is also not satisfied. The boss seems lost faith completely in other hydraulic relief valve manufacturers and agreed with Mason to regard AAK as their preferred supplier of hydraulic relief valves. It took Mason 2 years to persuade his boss to choose AAK hydraulic relief valves with 17% higher price, because he knows that the durability of AAK hydraulic relief valves is at least twice that of other manufacturers. Under complex working conditions, how does AAK ensure that the hydraulic relief valves have no cavitation and its durability is more than twice that of other manufacturers? 1. AAK hydraulic relief valve sleeve orifice processing, the opening adopts conical hole, not cylindrical hole of other manufacturers. Most hydraulic relief valve manufacturers do not have this ability to process conical hole. 2. The chamfering, deburring and polishing process is added at the orifice to further optimize the control edge, so as to reduce the cavitation caused by the flowing oil, and at least eliminate the cavitation within 2 years. Most hydraulic relief valve manufacturers did not expect that AAK has such a unique skill. 3. Devils are in the details. Most hydraulic relief valve manufacturers will ignore small details. Even if some factories think of them, they can't control the technology. AAK hydraulic relief valves, pay attention to every small detail, you can also have a small try! https://www.aakindustry.com/info-detai , l/hydraulic-relief-valves-aak222

Nelson comes from South Africa and purchases hydraulic solenoid cartridge valves from Ningbo. We have known each other for 2 years, but don't have much cooperation. Occasionally, there are only a few inquiries about hydraulic solenoid cartridge valves but without any results. Nelson advised that the price of AAK hydraulic solenoid cartridge valves is about 20% higher than that of solenoid valve peers in Ningbo. I listed how AAK's process ensured the manufacturing quality of hydraulic solenoid cartridge valves, but he did not respond. From the bottom of my heart, I have already given up on Nelson. Last February, Nelson suddenly approached me and asked for an AAK sample of a hydraulic solenoid cartridge valve. I felt a bit strange. After communication, it was learned that they are developing a new hydraulic power unit, and the engineer requires that the hydraulic solenoid cartridge valve must have a performance guarantee of over 1 year of service life. Nelson selected 3 hydraulic cartridge valve manufacturers in Ningbo to make samples at the same time. I am willing to accept such a challenge, jokingly asking Nelson :”Is AAK price acceptable?”. Nelson told me frankly that AAK price is 20% more expensive than the other two manufacturers. 1 month later, AAK sent the samples of the hydraulic solenoid cartridge valves. Yesterday, Nelson emailed us that AAK sample has been in use for over 1 year and the response is also fast. I asked about the testing status of the other two hydraulic cartridge valve manufacturers. Nelson informed us that they only have a service life of 6-9 months. Nelson realized that although AAK hydraulic solenoid cartridge valve is more expensive by 20%, it has no after-sales troubles. I told Nelson that this hydraulic solenoid cartridge valve has a working pressure of over 350bar and a lifespan of over 1 year, which is crucial in one detail. Most hydraulic cartridge valve manufacturers use argon arc welding for the welding of the magnetic isolation tube of this hydraulic solenoid cartridge valve, which can reduce the service life of the hydraulic cartridge valve by welding rough holes, welding deviation, welding stress, etc. 1. AAK hydraulic solenoid cartridge valve has an axial first oil port and a radial second oil port set at the front end of the valve sleeve. The inner cavity of the magnetic isolation tube has a fixed iron, which is connected to the valve sleeve at the front end and the magnetic isolation tube at the back end. The fixed iron is hollow and forms a cavity. The front end of the magnetic isolation tube and the rear end of the fixed iron are welded together through copper welding rings, replacing the argon arc welding technology of the same industry. 2. The coil is wrapped around the outer side of the magnetic isolation tube and the fixed iron, with an end cover at the rear end of the magnetic isolation tube. The valve sleeve has a valve spool that can move axially, a convex head at the front end, and a reset mechanism inside the valve sleeve. 3. The push rod in the fixed iron chamber can move axially and transmit the force of the moving iron to the valve spool. This structure can reduce the resistance of the moving iron movement, shorten the opening and closing time of the solenoid valve, play a magnetic isolation role, reduce the release time of the moving iron, and have a long service life under high pressure. Nelson privately mentioned that their engineers were very satisfied with the hydraulic solenoid cartridge valves he purchased this time. Unlike the previous hydraulic solenoid cartridge valves, there were always some difficulties, and the boss increasingly valued him. He is also more experienced in purchasing the hydraulic solenoid cartridge valves. AAK hydraulic solenoid cartridge valve, although more expensive by 20%, has a service life twice that of its peers.

Esteban is from a Spanish hydraulic equipment manufacturing company. Some time ago, their company customized a hydraulic cylinder for a customer. The hydraulic check valve, relief valve and electromagnetic unloading valve in the system are all standard parts from HydraForce. The customer is basically satisfied, but the cylinder structure is not very satisfactory, and the price has no advantage. Their engineer said that only by integrating the functions of hydraulic check valve, relief valve and electromagnetic unloading valve, and replacing them with only one hydraulic screw-in threaded cartridge valve, would the structure be simple and the cost be reduced. Esteban inquired about more than 10 hydraulic threaded cartridge valve manufacturers, but no result for a week. Esteban was worried. After browsing AAK website on Google, Esteban found that AAK had many cases of solving customer problems, and sent an email asking: Can AAK customize the multi-function hydraulic threaded cartridge valve to make the cylinder compact and reduce costs? After communication, it was learned that Esteban needed AAK to customize the hydraulic threaded cartridge valve to replace the functions of the 3 valves in the system. According to the hydraulic schematic diagram provided by Esteban, AAK engineers basically had the idea. Esteban asked for samples after knowing it. After 50 days, AAK sent 10 samples of hydraulic threaded cartridge valves. 1 month later, Esteban informed us by email that the customer was satisfied with the new structure of the oil cylinder, and should promote it first, and let us wait for the batch order. AAK used an integrated multi-function hydraulic threaded cartridge valve to replace the 3 valves of the original system, specifically as follows: 1. The valve housing is provided with a connecting valve hole, a working port of the oil cylinder, and a hydraulic control port, an oil inlet port and an oil return port. A check valve spool is set in the valve hole to control the on-off of the oil inlet and the working port for oil feeding or unloading. In this way, the one-way control function is realized and the check valve of the original structure is replaced. 2. The control check valve spool is separated from the working port, and the hydraulic control valve spool for unloading the oil inlet and the working port is connected. At the same time, the connection between the valve hole and the relief valve spool of the oil return port can also be disconnected. In this way, the overflow function is realized and the relief valve of the original structure is replaced. 3. The relief valve spool is equipped with connecting valve hole, oil return port and damping hole. One end of the damping hole is equipped with a unloading valve spool to control the opening and closing of the damping hole and the oil return port, and the check valve spool is equipped with a connecting channel to connect the valve hole and the working port for overflow or unloading. In this way, the unloading function is realized and the electromagnetic unloading valve of the original structure is replaced. AAK hydraulic threaded cartridge valve, can not only replace 3 valves of HydraForce with 1, but also realizing multi-function and flexible adjustment. AAK hydraulic thread cartridge valve, multi-function, with 3 valves into 1, you can also try it! https://www.aakindustry.com/info-detail , /cartridge-valve-manufacturers-aak471

Carver is from a hydraulic equipment company in Spain. He has engaged in purchasing hydraulic manifolds for 3 years, and has been smooth. At the beginning of this year, their company customized 2 sets of hydraulic units for a customer. The hydraulic manifolds used were from a local manufacturer. After 60 days, the equipment was successfully delivered to the customer. 1 month later, the customer reported that the hydraulic unit had stable performance and they were satisfied with its functions. However, they wanted to replace some hydraulic components to realize the multi-function of the equipment, but the complex structure of hydraulic manifold restricted this idea. According to the feedback of the original hydraulic manifold manufacturer, it would take 90 days to meet the customer's idea, and the cost would be increased by 50%. However, the customer did not accept the price increase, and can only give 60 days. The boss asked Carver to find a new hydraulic manifold manufacturer. He tried to contact more than 10 hydraulic manifold manufacturers, but it was fruitless after 1 week. The boss was not satisfied, Carver was worried. Carver browsed AAK at Google, noticed that AAK had released a series of customer cases about hydraulic manifolds, and left a message: Can AAK design and sample a compact multi-functional hydraulic manifold within 60 days, and it is also easy to install and maintain? I replied in 2 points: 1.Honeywell, one of the world's top 500 enterprises, is also a loyal hydraulic manifold customer of AAK. 2.AAK has tested 230 sets of hydraulic manifolds for 17 customers. Carver may have felt the specialty of AAK hydraulic manifolds. He sent me all the original drawings, even the complete set of drawings of the hydraulic unit. I received his trust in AAK. After half a day of internal discussion, AAK engineers came up with a plan, and were 90% confident to complete it within 50 days. Carver was surprised at the development time of AAK and satisfied with the price of AAK hydraulic manifold. I also told him that there was no need to worry about the manufacturing quality of AAK hydraulic manifold. Maybe AAK's progressiveness was not necessarily better than that of the Spanish manufacturers, but the reliability and stability of AAK hydraulic manifolds must be comparable, even better than that of Spanish hydraulic manifold manufacturers. After 50 days, AAK sent 5 sets of hydraulic manifolds. Yesterday, Carver emailed that the customer was very satisfied with their newly designed hydraulic unit. The internal hydraulic manifold is easy to install and replace, and the maintenance cost is also low. Carver placed an order for 500 hydraulic manifolds, and expressed his gratitude. He said that the hydraulic manifold designed by AAK was really different, especially in its compact structure, convenient installation and maintenance, and satisfactory performance after 6 months of tracking. Their customer was preparing the annual order, and he asked me to prepare the production plan in advance. AAK hydraulic manifold surpassed the Spanish manufacturers, due to the following 3 points. It may be difficult to find the third hydraulic manifold manufacturer like AAK in China. 1. Layout positioning is the foundation: engineer with 23 years of industry experience fromHAWE, use NGSA algorithm to intelligently optimize the external layout and internal hole layout, making the system circuit more stable. 2. Production process is the core: for hydraulic manifold design, AAK have a complete set of processes. From hole checking, wire network connection, hole network to component selection, oil circuit volume and assembly relationship, they are all precisely linked. The hydraulic manifold occupies less space, has less pressure loss, less leakage and less vibration. 3. High cost performance is the killer: AAK hydraulic manifold reduces pipeline connections and joints, reduces system complexity, and reduces energy consumption. Compact structure, convenient installation, low maintenance cost, less leakage and small vibration. AAK hydraulic manifolds, cost-effective is the trump card, and are supplied to the world’s top 500 Enterprises. You can also try a small order. https://www.aakindustry.com/info-detail/hy , draulic-manifold-manufacturers-aak403
