Blade is from Canada. He has been purchasing hydraulic components successfully for 3 years. Unexpectedly, a hydraulic cartridge directional control valve stumped him. In the second half of last year, a batch of their hydraulic logistics lifts were complained by customers, some of them were unable to work, probably because the hydraulic cartridge directional control valve leaked. After checking, it was found that the valve spool was deformed. The original manufacturer of the hydraulic cartridge directional control valves said that it had been shipped for 9 months, and some exceptions were inevitable. It is possible that the internal stress of the valve spool was not eliminated in time during the heat treatment process, resulting in deformation or cracking of the valve spool. However, there are more and more complaints later. Blade realized that the service life of the hydraulic cartridge directional control valves from the original cartridge valve manufacturer may be about 1 year. He had to find a new hydraulic cartridge directional control valve manufacturer with a service life of 2 years. A week has passed, and no one can guarantee a 2-year life span. Blade found AAK when browsing Google. He noticed that AAK was continuously supplying HydraForce, and left a message: Can AAK ensure that each hydraulic cartridge directional control valve spool is free of deformation or cracking within 2 years? I guess he encountered trouble in purchasing hydraulic cartridge directional control valves. After communication, I learned the above information. I replied that the life expectancy of 2 years should not be a big problem. Blade sent the drawing of the hydraulic cartridge directional control valve and asked for the lead time for 10 samples. After 45 days, AAK sent the samples of the hydraulic cartridge directional control valves, but there was no email from him after that. Last week, Blade suddenly sent an email, and it was a PO for 600 hydraulic cartridge directional control valves. It can be seen that the samples of AAK hydraulic cartridge directional control valve was approved by his customer. The valve spool is the key to long service life of this hydraulic cartridge directional control valve. 1. AAK select 20CrMo material to produce the valve spool. After quenching and tempering, the materials are more conducive to processing. Most hydraulic cartridge valve manufacturers ignore this action. 2. 0.25~0.35mm machining allowance shall be reserved for rough turning, then carburizing, quenching and high temperature tempering shall be carried out, and then the valve spool shall be subject to low temperature cold treatment. The surface hardness of such valve spool is above HRC63, and the residual austenite in the internal structure is eliminated. 3. The valve spool shall be subject to semi finishing, and 0.1-0.15mm allowance shall be reserved during the process, and then the valve spool shall be subject to tempering treatment. The temperature of tempering treatment shall be 320°C, and the temperature shall be kept for 5 hours, which can eliminate the residual internal stress and greatly improve its stability. After tempering the valve spool, the honing machine shall be used for finishing to ensure the accuracy and ensure that each valve spool meets the standard.

Beardsley is from Canada and has been working with hydraulic cartridge valve manufacturer AAK for 3 years, with an increasing number of inquiries every year. In early July this year, Beardsley asked me if there was a hydraulic cartridge flow control valve equivalent to HydraForce NV08-20? Can AAK complete the production of 300 pcs of hydraulic flow control valves in 20 days? It is the first time that I received such an urgent email from Beardsley, he was very calm in every purchase. After communication, I learned that their new colleague confirmed an order with a hydraulic cartridge valve manufacturer in Ningbo for 300 pcs of hydraulic flow control valves NV08-20. The hydraulic cartridge valve manufacturer promised a delivery time of 25 days, but 30 days have passed. However, the hydraulic cartridge valve manufacturer advised that it will take another 30 days because it is currently the peak production season for the hydraulic cartridge valve manufacturer. The new colleague is out of options and can only seek help from Beardsley. If without inventory and stock, to complete the production of 300 pcs of hydraulic flow control valves NV08-20 in 25 days is really difficult. Most hydraulic cartridge valve manufacturers in China just focus on domestic sales orders, and for export orders, these hydraulic cartridge valve manufacturers usually accept the orders first to fill the capacity gap. Once domestic sales orders arrive, they give priority to the domestic market orders. Beardsley is very aware of the current situation of hydraulic cartridge valve manufacturers in China, so he is very cautious when choosing hydraulic cartridge valve manufacturers, which is also the reason why he is sending AAK more and more inquiries. AAK has the program for hydraulic flow control valve NV08-20, confirmed the order for 300 pcs of hydraulic flow control valves with Beardsley the next day, and the production time is only 18 days. Beardsley asked about the reason for the fast delivery time, and I sent him a video of the machining of the hydraulic flow control valve cage first. The production of the valve cage is carried out by AAK using Japan's Mazak automatic CNC lathe, which does not require old technicians to ensure machining accuracy and the processing of the valve cage can be completed automatically. AAK has improved the feeding tray to a 30 degree angle, and the valve cage's material is arranged on the tray in a line, automatically entering the fixture of the lathe. After the system corrects the positioning, processing begins. After processing, the valve cage is automatically sent out. This kind of automated processing reduces the number of clamping times for technicians, which is more than 40% faster than most processing methods. AAK has been taking action to create hydraulic cartridge valve manufacturers for unmanned processes. Currently, hydraulic cartridge valve manufacturers who do not upgrade to unmanned equipment, may go to the end of their business in 5 years. What we can think of is the unmanned workshop of hydraulic cartridge valve manufacturers, which can minimize labor costs. The factory has fewer employees, greatly reduces management difficulty, and the key is to eliminate human error. I believe that the scale of future hydraulic cartridge valve manufacturers will no longer be measured by the number of workers, with a few or dozens of people. The key is the hydraulic cartridge valves produced in unmanned workshops, which have stable quality and low production costs. Who doesn't love them? I am now replying to Beardsley regarding the reason why AAK produces faster than other hydraulic cartridge valve manufacturers. 1. AAK uses equipment from the Japanese military industry, and I am not aware of the hydraulic cartridge valve manufacturers in Ningbo who have more efficient equipment than this. 2. The quality is equivalent to HydraForce and stable, and AAK is willing to purchase various raw materials in bulk. 3. Unmanned production workshop, with an efficiency 40% higher than most hydraulic cartridge valve manufacturers in China. Hydraulic cartridge valve manufacturer AAK, has 3 major guarantees for fast production, and you can also try it out!

Features: Fluid resistance is small, ball valve is one of the least fluid resistance of all valves, even if it is a reduced diameter ball valve, its fluid resistance is quite small. Thrust bearing reduces the friction torque of the valve stem, which can make the valve stem operate smoothly and flexibly for a long time. Sealing performance of the seat is good, the sealing ring made of polytetrafluoroethylene and other elastic materials, the structure is easy to seal, and the sealing capacity of the ball valve increases with the increase of the medium pressure. Valve stem seal is reliable, because the valve stem is only as if rotating without lifting movement, the packing seal of the valve stem is not easy to destroy, and the sealing capacity increases with the pressure of the medium. Because polytetrafluoroethylene and other materials have good self- lubrication, and the friction loss with the ball is small, so the service life of the ball valve is long. Lower mounted valve stem and valve stem head convex step to prevent the valve stem ejecta, such as fire caused by the valve stem seal damage, the convex step and the valve body can also form metal contact to ensure the valve stem seal. Anti-static function: set the spring between the ball, valve stem and valve body, which can export the static electricity generated by the switching process.

Recently, in Ningbo, the hometown of China hydraulic solenoid valve manufacturers, there was a story about China hydraulic solenoid valve manufacturer expanding production line for new orders, but orders did not come finally. In September last year, the manufacturer welcomed 4 American customers team who visited China hydraulic solenoid valve manufacturers, and it was said that the negotiation went smoothly. Customer will place bulk orders but are concerned about the production capacity of this China hydraulic solenoid valve manufacturer. The manufacturer promised the customer to double their production capacity within 4 months, and the customer was also satisfied and left. Then this hydraulic solenoid valve manufacturer promoted it everywhere, with major customers placing large orders, he needs to buy equipment and build new factories. Almost all hydraulic solenoid valve manufacturers in Ningbo knew this information. I learned that he started buying equipment and building factories, so I started to worry about him. The reason why poor people become poor lies in their cognition and the behavior guided by cognition. Our ancients taught us: ' making a fortune without fanfare.'. But whenever a poor person has a little money in hand, they even tell the world without even getting it! I have a relative who said 5 years ago that his family was going to be demolished. He predicted that he could get 5 million yuan, but the demolition has not been completed yet. My relative didn't have the money at that time, but how the money was distributed and spent was already arranged by him, and he even resigned from his stable job as a security guard for this. He also selected a house and a brand of car, and just waited for the money to arrive and went to pick up the house and car. He also planned to open a restaurant, partner with friends to discuss cooperation, and wait for the money to come in. His high profile is not without any benefits. At least among his peers, he enjoyed flattery and support. The rumors of demolition have fundamentally changed his life and disrupted his entire pace of life. For 5 years, he has been living in longing, but sadly, it is said that the government's plans have changed again and his area will not be demolished. Returning to the China hydraulic solenoid valve manufacturer to buy equipment and build a new factory, last week, the customer informed the manufacturer that they have chosen another China hydraulic solenoid valve manufacturer. When a person is hungry, there is only one worry, but once they are full, there will be countless worries. Because many troubles are resulted from overeating. Whether in business or in the production of hydraulic solenoid valves, making a fortune without fanfare is the kingcraft. AAK, a China hydraulic solenoid valve manufacturer, focuses solely on its own production and manufacturing quality. It eats as much as its capacity, and never greedily eats what is not its own.

The types of hydraulic cartridge valves can be classified from different angles. Sometimes, buyers who purchase hydraulic cartridge valves are confused. After all, they are not engineers. In order to classify more simply and intuitively, AAK HYDRAULIC VALVE describes the types of hydraulic cartridge valves from the most extensive installation point of view. In this way, we can divide the hydraulic cartridge valves into 3 types: Insert-type, Slide-in and Screw-in. Berge, an old British hydraulic valve customer, was transferred from the quality control department to the import department. He is a very studious buyer. Maybe it's fate, we often discuss some knowledge points about hydraulic valves. Some time ago, he didn't understand that every time, when the domestic hydraulic valve manufacturers receive an inquiry about his hydraulic cartridge valve, they always ask about the type of hydraulic cartridge valve. The question about the type of hydraulic cartridge valve made him very nervous and helpless. Indeed, there are many types of hydraulic cartridge valves now, from the perspective of function, hole type and scene. We found that they are most commonly classified from the perspective of installation, which is easy to understand and remember. I summarized our hydraulic cartridge valve types to Berge. After reading my following report about the types of the hydraulic cartridge valves, he told me that this classification for the hydraulic cartridge valve types can basically cover more than 80% of the hydraulic cartridge valves. Here, I'll also share with you the types of hydraulic cartridge valves I gave him. Common types of hydraulic cartridge valves are as follows: The Insert-type hydraulic cartridge valves: completely enters the inside of the valve block and does not expose any part outside the valve block. It is positioned by its own thread or other components such as pipe joint, snap ring, retaining ring etc. For example, hydraulic check valve and two-way hydraulic flow regulating valve have this design. The slide-in hydraulic cartridge valves: it does not have installation threads itself, and the valve spool needs to be used together with the cover plate. The valve spool is integrated in the valve block to switch the oil circuit on and off through pressure and spring force. Different cover plates are used to realize direction control, pressure control and flow control. Screw-in hydraulic cartridge valves, that is, hydraulic threaded cartridge valves, have different brands and different hole types, which are usually unable to be interchanged in installation. At present, there are 3 commonly used pass types: ISO7789, SAE and SUN. After understanding the above 3 types of hydraulic cartridge valves, you can basically understand the types of hydraulic cartridge valves, and you can also extend other types of hydraulic cartridge valves. These types of hydraulic cartridge valves are related to each other. AAK HYDRAULIC VALVE uses the most intuitive installation angle to describes the types of hydraulic cartridge valves. If you have any questions about the hydraulic cartridge valves, please leave a message on AAK website www.aakindustry.com. We are at your service at any time. https://www.aakindustry.com/info-deta , il/hydraulic-valve-manufacturers-aak93

Maarten purchased a batch of hydraulic valve blocks some time ago. In the early test, the system parameters were normal. Strangely, 10 days after the hydraulic valve block was started, the hydraulic oil in the system suddenly deteriorated. The technician immediately suspended the operation of the whole test system. After inspection, it was found that there were small iron filings in the hydraulic oil, and the valve spool of the cartridge valve connected with the hydraulic valve block also showed signs of wear. Maarten mentioned these problems to the hydraulic valve manufacturer, but the hydraulic manufacturer asked the customer to use better hydraulic oil and avoided the problem of his own hydraulic valve block. With delivery date approaching, Maarten is very helpless. Maarten really had no choice but to try to find other suitable hydraulic valve manufacturers on the website to take over the hydraulic valve block order. He consulted no less than 10 manufacturers in a week, but all manufacturers gave the same reply, they could not 100% avoid fine iron filings. This made Maarten start to doubt the ability of the hydraulic valve manufacturers in China. Before, Maarten had a certain understanding about us AAK hydraulic valve through some B2B websites, so with a try mentality, he directly emailed us a trial order for 5 hydraulic valve blocks. After receiving our hydraulic valve blocks, Maarten tested and compared, he found that AAK hydraulic valve block has strong sealing, high precision and gloss finish. What's more, he was glad that there was no iron filings residue. He immediately sent the drawings, quantity, delivery date and other detailed requirements of the hydraulic valve blocks currently being purchased from the other hydraulic valve manufacturer. After confirming all details with us, he cancelled the order with the original hydraulic valve manufacturer. At this moment, Maarten could finally rest assured. Why do more than 10 hydraulic valve manufacturers dare not accept the order of this hydraulic valve block? Because this hydraulic valve block is very special. There are many slender holes in the processing channels intersected by each hydraulic valve block, and the cleaning of iron filings is a cumbersome process. If there is no unique skill, it is difficult to eradicate it 100%. 2 years ago, AAK hydraulic valve also had an order cancelled by customer due to the iron filings of hydraulic valve block not completely eradicated. After that lesson, our technical team spent half a year innovating the production process of hydraulic valve block, and finally AAK hydraulic valve was able to mass produce the hydraulic valve without iron filings 1 year ago. The reason why AAK hydraulic valve block can remove the residual iron filings that can not be achieved by peers is that after the hydraulic valve block is processed, AAK firstly uses high-temperature alkaline water to cook the hydraulic valve block, so that the iron filings of the hydraulic valve block lose demagnetization, and then uses a small pneumatic grinding wheel to clamp the rotary file to go through the hole, so as to completely eliminate possible flash at the corner. Then, the high-pressure washing machine shall carry out high-pressure washing on the dirt on the inner and outer surfaces of the duct. Finally, the industrial endoscope and cold light source shall be used to check the flash and burr at the corner in the duct. If any, point-to-point and high- pressure washing shall be carried out until the iron filings in the hydraulic valve block are completely eradicated. AAK hydraulic valve block is made with ingenuity. Don't worry about buying and using. You can also try a small order.

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. Welcome to try it! https://www.aakindustry.com/info-detail , /pressure-control-cartridge-valves- aak511

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.
