AAK hydraulic pressure valve has no horn hole. In Ningbo, the hydraulic valve production base, few factories are sure to solve the horn hole. AAK uses automatic programming software to program and upgrade the processing technology of hydraulic valve cavity hole. The geometric tolerance of each hole is within 0.02mm. At the same time, small fillet is used to replace the R angle of our peers to transition, which completely avoids the horn hole. Most hydraulic valve manufacturers use manual programming to design the geometric tolerance of cavity hole, which is prone to human error and can not be corrected. At the same time, due to the limitation of operation methods, the transition angle between small holes in the hydraulic pressure valve generally adopts the R angle for transition, which is easy to artificially leave a small space that is not easy to detect, so the horn hole will probably appear. After the hydraulic pressure valve is used for a period of time, the horn hole is easy to leak. What's more troublesome is that the oil stain outside the hydraulic pressure valve is easy to enter the valve spool and damage the whole hydraulic system. Adair, a hydraulic valve purchaser in Scotland, had many contacts with AAK hydraulic valve before, because he pursues low price, there is no cooperation between us. In July this year, he placed an order for hydraulic pressure valve worth 80,000 US dollars to a hydraulic valve manufacturer in Ningbo. 2 months later, the quality of the hydraulic pressure valve failed to meet the standard every time. Adair realized that even if it took another 2 months, the sample still could not be approved. Adair accidentally saw an article from AAK about "horn hole" on the B2B website, he further sourced until he got to the AAK website: www.aakindustry.com, he realized that it was the hydraulic valve manufacturer he had been contacting. When we received Adair's email, we understood the problems and causes of his hydraulic pressure valve. 3 days later, we received the hydraulic pressure valve samples that he asked the original hydraulic valve manufacturer to send, we found that the processing coaxiality of the cavity hole diameter of the combined holes of these hydraulic pressure valves was between 0.03-0.05mm, and there were tool connecting traces at the transition R angle. After we took the video and sent it to him, he understood why the samples of the original hydraulic valve manufacturer were always not approved. After receiving the video, Adair transferred the order of this hydraulic pressure valve to us AAK hydraulic valve the next day. At the same time, Adair also joked that you found the problem, but not means that you are able to solve the problem. How does you AAK hydraulic valve do and make me believe that you can 100% solve these hidden problems. AAK hydraulic valve is good at finding the pain points of traditional process, and is more willing to take time to improve or innovate the production process of hydraulic valve. Many times, the process has been one step ahead of the peers. For example, this hydraulic pressure valve is programmed by automatic programming software, which replaces the manual programming commonly used by our peers. After the hydraulic pressure valve automatically generates the cavity hole, then next step is processed. The geometric tolerance of each hole must be controlled within 0.02mm. If it does not meet the standard, the next step of processing will not be carried out. At the same time, each transition angle between the small holes of the hydraulic pressure valve uses a small fillet to replace the common R angle of our peers. By optimizing the processing parameters of the cartridge hole, the horn hole is completely avoided. AAK hydraulic pressure valve has no horn hole, feeling at ease to use. You can also try a small order.

Alfredo is from Spain. He has been smooth in purchasing for 3 years, but was stumbled in the hydraulic pressure control cartridge valve. Last October, they developed a walking reducer that needed to purchase hydraulic pressure control cartridge valve. During commissioning, the equipment stopped unstably. Their engineer judged that the buffering function of the hydraulic pressure control cartridge valve was not up to standard. The hydraulic pressure control cartridge valve manufacturer said that this situation was caused by the inertia of the travel motor when it stopped, and had nothing to do with the hydraulic pressure control cartridge valve. Alfredo was helpless in the face of the push- off of the original manufacturer. Alfredo searched the website of AAK hydraulic valve on Google, and noticed several customer cases of AAK about hydraulic pressure control cartridge valves. He emailed us to ask: Can AAK customize the hydraulic pressure control cartridge valve to solve the unstable stop of the traveling reducer? At the same time, he also sent us the hydraulic schematic diagram and video of on-site debugging. AAK engineers analyzed that as long as the control structure of the original hydraulic pressure control cartridge valve was changed and the buffering function of the hydraulic pressure control cartridge valve was strengthened, the travel reducer could stop stably. Alfredo saw hope and asked AAK to make 7 samples of the hydraulic pressure control cartridge valves. After 50 days, AAK sent the samples of hydraulic pressure control cartridge valves. Two days before our CNY holiday, Alfredo informed us by email that the test run of the walking reducer was smooth and their engineers were very satisfied with the buffer function of AAK hydraulic pressure control cartridge valves, the prototype has been sent to customer and let me wait patiently for their annual purchase order. The structure of the hydraulic pressure control cartridge valve is optimized from 3 aspects and AAK realizes the buffering function of the hydraulic pressure control cartridge valve. 1. The inner chamber of the hydraulic pressure control cartridge valve body is equipped with 2 limit steps. There is a buffer outlet between the 2 steps. The plug is installed at the rear end of the valve body. The valve spool is installed in the valve body, and the pressure regulating spring and buffer are sleeved on the valve spool. One end of the pressure regulating spring is connected to the limit bulge of the valve spool, and the other end is connected to the buffer. The limit bulge of the valve spool is matched with the first limit step, and the buffer is matched with the second limit step. 2. There is an inlet at the front of the hydraulic pressure control cartridge valve body, and a return port between the inlet and the first limit step. The buffer cavity is between the plug and the buffer. The valve spool has an internal flow passage connecting the liquid inlet and the buffer cavity, and the internal flow passage has an orifice. 3. For leakage prevention, 6 sealing rings and 2 retaining rings are used. There is a first sealing ring between the plug and the valve body, and a second sealing ring between the buffer and the valve body. There is a third sealing ring between the limit bulge of the valve spool and the valve body. There are the first retaining ring and the fourth sealing ring on the periphery of the front end of the valve body, the second retaining ring and the fifth sealing ring on the periphery of the middle of the valve body, and the sixth sealing ring on the periphery of the rear end of the valve body. The optimized AAK hydraulic pressure control cartridge valve adopts the forward and reverse, as well as the same direction and two-stage opening mode. The two- stage opening pressure is independent and adjustable, reducing the system flow path, and the system has high and low unloading pressure, realizing the buffering function. AAK, a top cartridge valve manufacturer in China, its hydraulic pressure control cartridge valve is buffered, stable and reliable.

Most people are willing to admit that they are lazy rather than foolish, and most hydraulic manifold manufacturers are willing to admit that they are not proactive rather than foolish. It is dangerous to say that one is smarter than others. Hydraulic manifold manufacturer AAK prefers to say that AAK is harder and more hardworking than other hydraulic manifold manufacturers, so AAK is not very eye-catching among its peers in Ningbo. Sometimes, on the other hand, it's even more interesting. Some hydraulic manifold manufacturers may not say they are lazy or hardworking, but they seem to have made little progress. If you admit that you are not very smart and that you are a bit clumsy, it may actually be a safer way. With the wide range of hydraulic manifold types involved in AAK, for the hydraulic cartridge valves that AAK does not have a ready-made program, AAK needs to purchase them externally. Therefore, two hydraulic cartridge valve manufacturers were selected as cooperation intentions. For better management, only one hydraulic cartridge valve manufacturer can be identified from A and B as a partner of hydraulic manifold manufacturer AAK. Finally, our chief engineer chose hydraulic cartridge valve manufacturer B. I asked him the reason for determining B. His opinion was that both A and B's manufacturing quality were recognized. Hydraulic cartridge valve manufacturer A looked very smart, but hydraulic cartridge valve manufacturer B looked a bit clumsy. I understand what the chief engineer means now. When many people choose partners, they don't choose the smart one, but instead choose the person they think is a bit clumsy. Because most people's idea is to choose a smart partner, I may not be able to manage it, but choosing a clumsy one, I actually have everything in control. I remember 10 years ago, hydraulic cartridge valve manufacturer AAK was upgrading to a hydraulic manifold manufacturer. When Honeywell chose AAK as the supplier, their purchaser said something: from the manufacturing quality of AAK hydraulic cartridge valves, I saw the quality of AAK's hydraulic manifold production. AAK engineers can select valves based on the oil circuit diagram to complete the hydraulic manifold function. They can create three-dimensional hydraulic manifold drawings according to customer requirements, and design valves with the same function according to the customer's required cavity size to fit with hydraulic manifolds. He knows that many hydraulic manifold manufacturers in China can only do replication, but AAK has the potential to move from ideas to samples. More importantly, AAK is pragmatic and looks a bit clumsy. Interestingly, this is a bit clumsy, but it will actually give me a choice. Moreover, it tells my Fortune 500 clients that hydraulic manifold manufacturers are very hardworking, but they don't seem to be so top-notch and smart. It's okay just get to know the Fortune 500 clients. You can play with me and I will work hard to seize the opportunity you give me. The years when I first started working, I was the same. I never told my boss that I was very smart. I often tell my boss that I am actually a bit foolish, but I will work hard and resolutely execute the orders given by my boss. If there is anything wrong with me, the boss will promptly criticize and correct me, guide me to improve, and I have gained more favor from the boss. Hydraulic manifold manufacturer AAK is a bit foolish, but it works hard and the manufacturing quality is definitely good.

Chapman comes from a hydraulic equipment manufacturing company in Italy. He has been in the company for 3 years and is highly regarded by his boss. However, the hydraulic pilot relief valves purchased at the beginning of the year has been in a big trouble, which makes his boss more and more disappointed with him. They sold a batch of hydraulic power units, and there was squeal or vibration. They judged that it was caused by the abnormality of the hydraulic pilot relief valve. However, when they tested the hydraulic pilot relief valve separately, the parameters met the standard, and no abnormality was found. In a week, Chapman contacted different hydraulic valve manufacturers online and offline, but it was fruitless. The original manufacturer of the hydraulic pilot relief valve could not provide constructive suggestions. The boss is urging the after-sales plan. Chapman has not found the root cause of the equipment howling yet and has a big headache. Chapman tried to source Chinese hydraulic valve manufacturers on Google. He was surprised that AAK's natural ranking in Google actually ranked on the home page. He left a message to ask if AAK could solve the squeal of the hydraulic pilot operated relief valve. I didn't answer yes or no, but only sent him two links about the squeal solution of the hydraulic valves. AAK has solved the squeal of the hydraulic relief valves for 2 customers. 10 minutes later, Chapman sent the drawings of the hydraulic pilot operated relief valve and the product pictures of the original manufacturer. Our engineer asked him to separate the hydraulic relief valve into two halves along the axis of symmetry, with partial drawing pictures. The next day, I told him that it was not difficult to stop whistling, it is better to make samples directly. After 50 days, AAK sent 40 samples of hydraulic pilot operated relief valves for him to replace the ones on the equipment complained by customers. Last week, Chapman sent a PO for 360 hydraulic pilot operated relief valves, and told that it had been 6 months since AAK hydraulic pilot operated relief valves have been used on the equipment. There was no customer complaint about squeal or vibration, and the customer was satisfied. His boss asked him to replace all the original hydraulic pilot operated relief valves and only choose AAK. Different hydraulic relief valves have different causes of squeal, it needs a case by case analysis. Our engineer found that the dynamic performance of this hydraulic relief valve was not very smooth, so he set dynamic damping in its valve spool cavity. This damping and spring cavity constitute a first-order inertial link. The turning frequency is higher than the natural frequency of the second-order oscillating link of the valve spool, which can form an inter stage dynamic pressure feedback, improve the dynamic process, and effectively reduce the vibration of the dynamic process. The greater the vibration, the stronger the damping effect. AAK hydraulic pilot operated cartridge relief valve, no squeal, no vibration, you can also have a small try! https://www.aakindustry.com/info-detai , l/hydraulic-pilot-operated-relief-valves- aak38 , 3

Yesterday when I arrived at the workshop, a colleague said that engineer Mr. Li had undergone significant changes, which surprised and comforted me. 2 years ago, China hydraulic solenoid valve manufacturer AAK wanted to hire a full-time hydraulic solenoid valve engineer. During the interview, Mr. Li answered the questions about the knowledge of hydraulic solenoid valves professionally, but showed a dull performance in other aspects. After hesitating for a day, I still hired him because his expertise in hydraulic solenoid valves conquered me. After a three-month probationary period, the chief engineer of AAK, the China hydraulic solenoid valve manufacturer, did not recommend hiring Mr.Li because it is difficult to get along and communicate with Mr.Li, but I still signed a work contract with Mr.Li. My philosophy: When choosing people, you should choose people with shortcomings, and never choose perfect people. What kind of person is perfect? Communicating with him seems impeccable, and then we can't see any shortcomings. At the same time, his strengths are not particularly obvious. Perhaps most China hydraulic solenoid valve manufacturers, when looking for experienced people in their daily lives, would choose such a person. But what I want to say is that after selecting such a talent, basically he cannot achieve performance that exceeds your expectations. Generally speaking, a particularly outstanding talent is often particularly strong in one aspect, while also being particularly weak in another direction. Our engineer Mr.Li has a particularly strong technical ability in hydraulic solenoid valves. But his interpersonal skills are really weak and he is not very talkative. In those projects that need technical teams to assist each other, there are often some other colleagues offended by him, and he just has a thick skull in interpersonal relationship management. The chief engineer of AAK, a China hydraulic solenoid valve manufacturer, has complained to me multiple times. In the first time, I said, 'Let's treat Mr. Li as a child. We don't need to argue with children.'. In the last time, I patiently said to the chief engineer, “do you think the ability to handle interpersonal relationships is more important for Mr. Li's position, or is his professional and technical skills more important?” The chief engineer of AAK, the China hydraulic solenoid valve manufacturer, said that of course, it is the professional technical ability. I said to the chief engineer of AAK, a Chinese hydraulic solenoid valve manufacturer, “why don't you use his professional technical skills as an engineer but want him to be a person who is particularly skilled in handling interpersonal relationships? As the technical leader of AAK, a China hydraulic solenoid valve manufacturer, aren't you the one who makes up for his shortcomings?” The chief engineer of China hydraulic solenoid valve manufacturer AAK seems to have awakened, starting to create opportunities for Mr. Li, how can he improve Mr.Li’s relationship with other members? In the hydraulic solenoid valve project meeting, let Mr. Li talk about his past experience first, so that others can better understand his way of thinking. Then, talk the specific views of the chief engineer about the project, so that everyone can understand Mr.Li’s logic. Mr.Li’s changes have been significant. I was surprised by his growth and pleased with the progress of the team. There is no perfect individual, only a perfect team. China hydraulic solenoid valve manufacturer AAK, selects talents with shortcomings.

Pancrazio is from a hydraulic equipment company in Italy. In recent years, his purchase of hydraulic valves in China has been smooth. Recently, he was trapped by a 450bar high pressure hydraulic cartridge relief valve. At the beginning of last year, their new hydraulic power unit was complained by customers about unstable pressure supply 6 months after it was sold. During after sales checking, it was found that the hydraulic cartridge relief valve spool was not flexible. The original manufacturer of the hydraulic cartridge relief valve advised that under 450bar high pressure frequency use, the valve cage was deformed, then the valve spool was not flexible, the only solution is to replace the valves with new ones. Later, with more and more complaints, Pancrazio realized that the service life of the hydraulic cartridge relief valves produced by the original manufacturer was only 6-9 months. Such frequent replacement is not affordable, they must find a new hydraulic valve manufacturer, the service life of the hydraulic cartridge relief valve must be more than 24 months. Pancrazio contacted more than 10 manufacturers, but none of them was able to guarantee that the service life of the hydraulic cartridge relief valve under 450bar high pressure, can be 2 years. 2 weeks passed, but no progress. Pancrazio became panicky. Pancrazio saw in Google that AAK released a series of 450bar pressure resistant hydraulic cartridge valves and left a message asking: How long is the service life of AAK's 450bar pressure resistant hydraulic cartridge relief valve? There are similar messages every day. I only answered "The price of AAK hydraulic cartridge relief valve is 20% higher, but its service life is twice that of the peers". In the afternoon of the same day, I received the drawings of the hydraulic cartridge relief valve and the pictures of the original manufacturer's hydraulic cartridge relief valves from Pancrazio. He emphasized the requirements of the 450bar pressure resistance and the service life of 2 years. Our engineer is a little surprised that the original manufacturer's hydraulic relief valves will be abnormal in 6 months. After a careful look at the design of the original hydraulic cartridge relief valve, we had an idea and suggested making samples directly. Although Pancrazio was some hesitant, there was no better choice. After 45 days, AAK sent 50 hydraulic cartridge relief valves to replace the ones on those abnormal equipments. Last week, Pancrazio emailed us that AAK hydraulic cartridge relief valves have been installed in the equipment for 1 year, there was any complaint about unstable pressure supply. Their engineers realized that AAK had directly modified the design of the original hydraulic cartridge relief valve, and they admired our minds. I told him that if there was no accident, in 24 months, there would be no repair report for AAK hydraulic cartridge relief valve and no complaint from the customers. This hydraulic cartridge relief valve, hydraulic system and working conditions are a little special. The original hydraulic cartridge relief valve is designed to be composed of a valve cover, a valve cage and a valve spool. Most hydraulic valve manufacturers mainly focus on standard parts and can only produce according to drawings, without system knowledge of hydraulic valves. We operate like this, which is the 3 points admired by their engineers. 1. We open a large round hole in the center of the upper part of the valve cover, and the valve spool reaches the valve cage through the large round hole and is installed in the inner cavity of the valve cage. This is the change of the appearance. 2. Enlarge the valve spool diameter and valve cage inner diameter in the same proportion, increase the valve spool stroke, increase the oil flow, and make the system oil more stable, which is helpful to the performance. 3. The area around the oil outlet of the valve cage is designed to be convex, and the high-pressure oil flows out through the outlet of the valve cage, which has a buffer, which is more resistant to high pressure and has better performance. The price of AAK hydraulic cartridge relief valve is 20% more expensive, but its service life is twice that of its peers. You can also have a small try! https://www.aakindustry.com/info-detai , l/hydraulic-cartridge-relief-valves- aak382

The original manufacturer of the hydraulic manifold block made samples for 3 times, pushed the delivery for 3 times, but the samples were still not approved. There was always 0.5~1.0mm burrs in the deep hole of the hydraulic manifold block. After AAK took over, in terms of process, it abandoned the conventional route, optimized 3 points, and got the samples approved at one time.   Tom from Holland, their customer wanted to develop a hydraulic manifold block. The maximum side length of the hydraulic manifold block is 800mm, including multiple 4 × M8 threaded holes and Φ 14、 Φ 17 deep holes, and the accuracy is more than 10% higher than the conventional one. Tom knew the difficulty of this hydraulic manifold block and the importance of this customer, so he selected 2 most recognized hydraulic manifold blocks manufacturers to make samples at the same time. It took 8 weeks to sample 3 times, and there were still 0.5~1.0mm burrs in the deep holes of the hydraulic manifold blocks. The customer was not satisfied. If the next sample of the hydraulic manifold block still can not be approved, the order had to be cancelled. Within 2 days, Tom contacted more than 30 hydraulic manifold block manufacturers, and those old suppliers suggested him giving up, which made Tom very anxious.   Tom found AAK website on B2B and noticed AAK has tricks on the processing and deburring of hydraulic manifold blocks. With the attitude of trying, he contacted us. When receiving the drawing of hydraulic manifold block sent by Tom, AAK technical team was also a little surprised. The hydraulic manifold block is large size but with long and thin holes, and most of the holes are Φ 14、 Φ 17. The depth is more than 400mm, most of which are deep holes with a length diameter ratio greater than 28. This is a challenge for machining, especially for deep hole machining. The tool is long, chip removal is difficult, chip extrusion is easy, and the drill bit is easy to break, with many potential burrs. 2 days later, AAK technical team had a commencement plan. I replied to Tom by email that AAK was willing to develop this hydraulic manifold block and is 90% confident to be successful.   After 30 days, we sent 5 hydraulic manifold blocks. 2 weeks later, Tom emailed us that the customer had approved AAK hydraulic manifold blocks, which not only met the accuracy standard, but also completely removed the burrs. For the deep hole processing of this hydraulic manifold block, the other hydraulic manifold block manufacturers can not meet the precision and remove burrs completely, maybe they still use traditional technology. AAK has always adhered to process innovation and technology optimization. Aiming at the characteristics of this hydraulic manifold block, AAK has made adjustment and optimization from 3 aspects:   1. Most hydraulic manifold block manufacturers use machine tools and gun drills to process deep holes. The deviation of this hydraulic manifold block hole reaches 1/800. AAK selects a machining center and adopts the two end butt joint processing technology. First, use an alloy milling cutter to process a certain depth of the guide hole, and then use a short to long fried dough twist drill to process the deep hole, and strictly control the deviation error range of the hole.   2. Adjust the traditional cutting speed, feed rate, cutting rate and other parameters. AAK adopts the cutting speed of 160m/min, feed rate of 0.25mm/r, and cutting rate of 0.5~2.0mm, which improves the cutting direction of burrs, avoids 0.5~1.0mm additional burrs occurred during processing.   3. Before assembly, use kerosene circulation and ultrasonic cleaner to wash the hydraulic manifold block for more than 1h, remove dirt, chips, fine burrs etc. on the hole wall, and then inspect with the endoscope.   AAK hydraulic manifold block, processing does not produce extra burrs, welcome to try! https://www.aakindustry.com/info-detai , l/hydraulic-manifold-blocks-aak438

For the processing of the main valve hole of the hydraulic cartridge relief valves, AAK uses a new 4-step method instead of the traditional 4-step method, which is 100% burr free. Rubio from Mexico, placed the big order 1 week after the first test order. Regarding the burrs in the main valve hole of the hydraulic cartridge relief valves, it involves 2 parts: how to effectively avoid and remove them. How to effectively avoid is the root cause. How to remove is the symptoms. AAK focuses on the root cause, while other hydraulic valve manufacturers pay attention to the symptoms. Burr is common in machining. As for how to control the burr in the main valve hole of hydraulic cartridge relief valve, most hydraulic relief valve manufacturers ignore the dead corner in the undercut groove. No matter how to clean it, the pain point of "black under the light" cannot be solved. 2 years ago, Rubio purchased the hydraulic cartridge relief valves from China for the first time, and almost overturned. For a hydraulic cartridge relief valve with a rated pressure of more than 30MPa, and a clearance of 0.006 ~ 0.01mm between the valve body and the valve spool, samples were made by 4 hydraulic valve manufacturers successively in 8 weeks. The parameters of each sample of the hydraulic cartridge relief valve were qualified during independent testing. However, once it was installed on the equipment and tested, the hydraulic system would not function very well. The root cause is the burr residue in the dead corner of the hydraulic cartridge relief valve cutting groove. Rubio browsed a series of articles about the burrs of AAK hydraulic valves and hydraulic valve blocks on the B2B website. When Rubio learned that HydraForce, SUN Hydraulics, are also loyal customers of AAK for more than 5 years, he seemed to be in no worry. According to the technical parameters provided by Rubio, we have existing procedure for this hydraulic cartridge relief valve. We sent 5 samples of hydraulic cartridge relief valves the next day. For the machining of the main valve hole of the hydraulic cartridge relief valve, AAK uses a new 4-step method instead of the traditional 4-step method, which is 100% burr free. 1 week after Rubio received our test samples, he sent the PO of 600 hydraulic cartridge relief valves. The undercut of the main valve hole of the hydraulic cartridge relief valve is the place where the most burrs are generated. The traditional processing route is: first rough boring, then semi fine boring, then milling the undercut, and finally reaming. After reaming, the burrs generated are in the same direction with the axis line of the hole, and sink into the undercut, forming the burr residues in the dead corners of the undercut, which cannot be 100% removed. We do not ignore this pain point. After several rounds of technical reform, we optimized a new 4 step method: first rough boring, then semi fine boring, then reaming, and finally milling the groove. The burr found after processing is perpendicular to the axis line. The burr here is visible and can be removed, and it is easy to remove without leaving dead corners. AAK hydraulic cartridge relief valve, burr free, valve not stuck, welcome to try! https://www.aakindustry.com/info-d , etail/hydraulic-cartridge-relief-valves- aak381

Arslan is from Türkiye. A set of hydraulic power unit developed by them requires the use of HydraForce standard hydraulic solenoid cartridge valve SV08-20. Arslan was overwhelmed by their engineer. The SV08-20 provided by 3 hydraulic cartridge valve manufacturers has a very small proportion of impurities. The engineer requires that both the sample and shipment of hydraulic solenoid cartridge valve SV08-20 must be free of any impurities. Arslan has contacted more than 10 hydraulic cartridge valve manufacturers, and none of them are 100% confident about no any impurities in each hydraulic solenoid cartridge valve. Arslan is anxious. Arslan found the hydraulic cartridge valve manufacturer AAK and left a message: Can AAK provide a 100% impurity free hydraulic solenoid cartridge valve SV08-20? After communication, I learned that Arslan's engineer has very high requirements for the model SV08-20, like a cleanliness obsession. I can feel Arslan's helplessness. I told Arslan that in a similar situation, hydraulic cartridge valve manufacturer AAK encountered it 5 years ago. After optimizing the original processing process, we added an ultrasonic cleaning process for hydraulic solenoid cartridge valves, and I took a video of our cleaning process for Arslan. The next day, Arslan replied that none of the 3 hydraulic cartridge valve manufacturers that originally provided SV08-20 had this process. I estimate that most hydraulic cartridge valve manufacturers do not set up this process. This is a hydraulic solenoid cartridge valve cleaning equipment independently developed and designed by AAK at Honeywell's request 5 years ago. This is a benefit of working with high-end customers, as they will take you step by step to improve and make orders and payments easily. Arslan does not need AAK to send samples and asked me to deliver 100 pcs of hydraulic solenoid cartridge valves SV08-20 to his factory. Arslan said he was scared by the pushing from their engineer. I jokingly said that AAK hydraulic solenoid cartridge valve SV08-20 can turn his worries into safety and will not delay the promotion of their hydraulic power unit. The hydraulic solenoid cartridge valve SV08-20 of AAK is free of impurities and dust, and the key lies in AAK's innovative ultrasonic cleaning process for hydraulic valves. We set it up in 3 steps. After the assembly of the hydraulic solenoid cartridge valve, the baskets are neatly arranged, and the automatic guide rail enters the ultrasonic cleaning equipment for 15 minutes before being automatically exported. Enter the drying equipment, after 6 minutes, enter the oil drain container and soak the hydraulic solenoid valve for 3 minutes. After leaving it empty and draining the oil, the hydraulic solenoid cartridge valve enters the packaging process. AAK hydraulic solenoid cartridge valve SV08-20, is innovative in cleaning, and you can also give it a try.

Go to bed early, read more and exercise more. I have been doing this for 23 years. Do these 3 things every day. If no good result, I will compensate for the failure. One of the most important words I have said to my children is to read or exercise when you don't know what to do. Go to bed early in order to get up early, do things for 2 hours when your brain is most awake. No matter what you do, the effect is surprisingly good. Read or write, finish 70% of the most important things today. I have been practicing for nearly 23 years. Read so as not to fall behind. Both skills and cognition need to be constantly improved and expanded. The progress of our predecessors is the ladder for future generations. Absorb knowledge from experts, digest and export, it is sure that you will not lose to your peers. Exercise is not only for health, but also to activate and transform the brain. It makes you better than yourself in many aspects, such as learning, doing things and doing business. It also makes you better than others. Many people believe that time management is about managing time. In fact, the focus of time management is to manage your mind, your body, and your goals. Regardless of genetic factors, people's thinness comes from hunger one meal after another; People's good skin is controlled by controlling hot and sugar. One day, when you have tasted the viciousness of people's hearts, the unbearable love, the pressure of money, and the ruthlessness of society, you will understand that there must be an “umbrella”. Stick to the above 3 things. I dare not say that there will be 3 umbrellas, at least 1 for you. Some people said that Marx would cry after reading the book Work, Consumerism and the New Poor by Mont Bauman. I deeply realized from the book that people can't think about things they don't know. Bowman discussed the work ethics before 1850 and its formation. Judging by the current values, it is simply hell on earth. What drives American industrial progress is not work ethics, but enterprise spirit and the desire to join the upper class. The book is really worth reading, otherwise it seems to live a little too self aware, but actually confused. Of course, for many people, this is also a useless book. AAK hydraulic valve insists on writing every day, no matter how well it is written, it must be written every day, with 1000 words of original writing every day. I don't care how others evaluate my writing ability. Writing ability is always from low to high step by step. Writing is a basic skill. No matter how much you listen to classes and read, if you only input but not output, just like Grandiose Aims but Puny Abilities. Look down on others, but not skilled; Learned a lot, but can't make use of it. Writing doesn't need too much material conditions, just a piece of paper, a pen or a keyboard. When customers encounter difficulties and miscellaneous problems of hydraulic valves, you can solve the problems with your ideas, write, create confidence in your heart, and also awaken your spirit. The really smart people have done enough stupid kung fu of the long-term doctrine. They adopt the most stupid method without any skills, just like the tortoise and rabbit race. Finally, the tortoise won the rabbit race. I take 10 years as a cycle and do in the dumbest way, instead of learning the skills of "taking shortcuts". I am also stupid. It took me 2 cycles to make a little success, which is far from success, maybe far from even a small success. If you are lazy a little every day, for 365 days, how many peers will you lose to? If you write a tweet every day, for 365 days, you will defeat 99% of your peers. What's the use of tweets and videos without high-quality content, even if you catch traffic by skills? Traffic is the result of the brand winning the hearts and minds, but not the base, otherwise, it is putting the cart before the horse. Now, it seems that there is no shortage of them, and the only one is attention. AAK hydraulic valve uses a "unique perspective" to make it clear that, the most noteworthy point is the cognitive resources of the industry. The hydraulic valve does not need entertainment and emotion, but only features content. AAK hydraulic valve, focus on what is relevant to you. https://www.aakindustry.com/info-detai , l/hydraulic-valves-380

Laertes, from Greece, has been cooperating with AAK for 3 years, mainly purchasing standard parts of cartridge valves of HydraForce. Last year, he needed to purchase a hydraulic directional control cartridge valve benchmarking HydraForce to develop their pile driver, but AAK did not have the procedure for this cartridge valve, and then no further news from him. I thought he directly purchased from HydraForce. It was not until last December that Laertes asked me the fastest time to customize the hydraulic directional control cartridge valve, then I knew that he had purchased the hydraulic directional control cartridge valve from a cartridge valve manufacturer in Ningbo. During the equipment commissioning, the pile driver started slowly and had general stability. Their sales did not think that it was up to par. The engineer analyzed and suggested that the external control system should be connected or the high-frequency reversing function of the hydraulic directional control cartridge valve should be added. The boss asked to improve the hydraulic directional control cartridge valve, but the original hydraulic directional control cartridge valve manufacturer said that this is a standard part of HydraForce and cannot be improved. Laertes had to contact AAK cartridge valve again. According to his hydraulic schematic diagram, production drawings of hydraulic directional control cartridge valve and equipment working video, AAK engineers said that adding the high-frequency reversing function to the hydraulic directional control cartridge valve can indeed avoid the slow vibration of the equipment and improve the stability. The directional control of AAK is to control the valve spool through oil circuit switching, and realize the commutation frequency adjustment of the hydraulic directional control cartridge valve. Laertes paid the development fee on the second day. After 35 days, AAK sent 12 samples of hydraulic directional control cartridge valves. Yesterday, Laertes informed by email that after replacing with AAK hydraulic directional control cartridge valve, the pile driver was debugged smoothly, and the vibration of the pile driver was fast, the power density was high, the stability was good, and the high frequency and large flow could be met. The AAK optimized hydraulic directional control cartridge valve has one more function than the standard part of HydraForce. 1. The AAK hydraulic directional control cartridge valve body has multiple valve holes and multiple main oil passage ports, and the valve holes are interconnected. 2. Two throttle valve spools are installed on the control flow channel between the oil chambers on both sides of the main oil circuit switching valve spool and the control oil circuit switching valve spool. The flow area of the two throttle valve spools can be adjusted. The pressure reducing valve spool is installed on the control flow passage between the main oil passage port and the control oil passage switching valve spool. 3. There is a control oil passage port on the valve body for connecting the external control oil passage. The oil pressure area of the control oil chamber at both ends of the control oil switching valve spool and the main oil circuit switching valve spool is different. Under normal pressure, the oil pressure acting area of the oil chamber is smaller than that of the variable pressure oil chamber, which can realize the differential connection of the control oil circuit. By controlling the movement of the oil switching valve spool and the main oil circuit switching valve spool, the main oil circuit switching is realized. By adjusting the flow area of the two throttling valve spools, the oil resistance of the control oil chamber is changed, the movement speed of the main oil circuit switching valve spool is changed, and the reversing time is adjusted to realize the reversing frequency adjustment of the hydraulic directional control cartridge valve. AAK, a cartridge valve manufacturer in China, its hydraulic directional control cartridge valve has one more function than the standard parts of HydraForce. You can also try it! https://www.aakindustry.com/info-detail , /directional-control-cartridge-valves- aak510

Vladilen is from Russia. Recently, he was heartbroken by a hydraulic directional control valve that is to be used in chemical engineering and needs to be corrosion-resistant for over 1 year. AAK does not adhere to conventional material selection, replacing traditional carbon steel with stainless steel, and has skilled processing of stainless steel, achieving an accuracy of within 2μm, helping Vladilen received a big order finally. At the beginning of this year, a hydraulic system used in a chemical plant required a hydraulic directional control valve, and anti-corrosion for more than 1 year was a challenge. Vladilen asked more than 10 hydraulic directional control valve manufacturers, but none of them were not able to meet the requirement of chemical anti-corrosion for 1 year. Vladilen left a message on the AAK hydraulic valve website: Can AAK produce hydraulic directional control valves for use in chemical plants that are corrosion-resistant for more than 1 year? I told him that stainless steel needs to be used to replace traditional carbon steel in the production of valve bodies, but the difficulty of cutting stainless steel is high, the cutting temperature is high, and the tool life is short. Not only is efficiency low, but the surface accuracy of the valve cage is also a major obstacle. Most hydraulic valve manufacturers in China may consider using stainless steel to produce valve bodies, but they cannot master the processing efficiency and accuracy and have to give up. Our suggestion may have given Vladilen hope, he directly requested AAK to make samples. After 50 days, AAK sent out 30 samples of hydraulic directional control valves with stainless steel valve bodies. Last week, Vladilen placed his first order for 500 hydraulic directional control valves. Their engineers are very satisfied with the accuracy of AAK samples, especially the valve hole accuracy not exceeding 2μm. The better news is that AAK hydraulic directional control valves have been recognized by their testing and can withstand corrosion for more than 1 year. AAK hydraulic directional control valve used in chemical plants can be corrosion-resistant for more than 1 year, due to 3 advantages: 1. For the material selection, we dare to use the most difficult to cut stainless steel to produce valve bodies. This is the most solid barrier for corrosion prevention for more than 1 year. 2. The processing of stainless steel materials uses Baker reamers imported from Germany, made of high cobalt steel material, with sharp and smooth edges, smooth hole walls, and an accuracy of within 2μm. 3. Equipped with DC-507 semi synthetic cutting fluid, its special cooling performance easily reduces cutting heat, and its lubricity, permeability, and rust resistance are the most suitable for stainless steel cutting needs, while also protecting the tool. AAK hydraulic directional control valve, used in chemical plants and corrosion- resistant for more than 1 year, you can also try it out!

March comes from Brazil, and their power unit is used in a relatively niche market. The hydraulic cartridge valves used are mostly non-standard. They used to purchase from hydraulic cartridge valve manufacturers in Europe, and apart from being expensive and slow in time, everything else was fine. Recently, he has been trying to purchase from hydraulic cartridge valve manufacturers in China, and the customization time has been also slow. However, the quality and functionality of the Chinese hydraulic cartridge valve manufacturers he has chosen are more troubled than those in Europe, which makes March very upset. March left a message on the website of hydraulic cartridge valve manufacturer AAK: 1. Are you interested and capable of customizing non-standard hydraulic cartridge valves? 2. According to my drawings, what is the lead time for customized hydraulic cartridge valves? 3. Is there any guarantee for the stability of the hydraulic cartridge valve function? After email communication, we learned that when purchasing non-standard parts from Chinese hydraulic cartridge valve manufacturers, he encountered difficulties with the functionality of hydraulic cartridge valves. After several rounds of communication, March may have confidence in the hydraulic cartridge valve manufacturer AAK and sent us the drawings, as well as the samples from the original hydraulic cartridge valve manufacturer. Whether it is the contour size of hydraulic cartridge valves or the internal structure of hydraulic cartridge valves, they are very unpopular. Our technical department is not 100% confident either. In order not to waste March's time, I suggest that he customize at the same time with previous suppliers such as European hydraulic cartridge valve manufacturers and AAK. If AAK customization fails, the development fee will be refunded. 3 months later, after internal testing by AAK, non-standard parts were sent out. March seems not excited either. The samples from the original Chinese hydraulic cartridge valve manufacturer also took 3 months, but after 2 weeks of internal use, the function of the hydraulic cartridge valve became abnormal. 1 month after the sample was sent out, March sent us an email to advised that the samples customized by AAK has undergone internal testing for 1 month, which has basically been recognized by their engineers. Once their power unit is confirmed by the customer, AAK's hydraulic cartridge valve will truly pass the standard. I told March that based on our internal testing curve, I am not worried about the stability of the hydraulic cartridge valve function unless there is a change in external working conditions. The customized hydraulic cartridge valve of AAK uses a self-developed functional testing platform for functional testing. The customized hydraulic cartridge valve is installed into the simulated valve block inside the equipment, connected to the electromagnetic coil, and started to be tested after startup. The valve spool is automatically opened, and the hydraulic oil begins to work. Where it goes, the flow and pressure curves of the hydraulic cartridge valve will be displayed on the display screen of the equipment. After 3 seconds, the valve spool will automatically close, and the flow and pressure curves at the time of closure will also be generated synchronously. The obtained curve is very systematic and visually assesses the function of the hydraulic cartridge valve. Then, perform the same test again, but increase the working condition by 20%. Most Chinese hydraulic cartridge valve manufacturers rely on data and experience to judege the function. There may not be a dynamic curve in their testing. Even if there is, it may not perform every test twice. Yesterday, March sent us an email and their power unit was confirmed by the customer. They also received the customized samples from Europe, but they decided to choose AAK hydraulic cartridge valve, which is not only fast and stable in function, but also more than 30% cheaper than hydraulic cartridge valve manufacturers in Europe. For customized hydraulic cartridge valves, AAK may not be inferior to hydraulic cartridge valve manufacturers in Europe.
