Karl is from Sweden. He purchases the standard parts of hydraulic cartridge valves from Italy, and the customized parts of hydraulic cartridge valves from Ningbo. Some time ago, when they developed hydraulic drilling equipment, they needed to customize the hydraulic cartridge needle valve. He made samples in a hydraulic cartridge valve manufacturer in Ningbo. Due to the unstable pressure control of the hydraulic cartridge needle valve, the selling point of the new hydraulic drilling cannot be realized. The Italian hydraulic cartridge valve manufacturer has no time to customize. The engineer pushed, and Karl was very anxious. This Ningbo manufacturer contacted me and hoped that AAK would develop this hydraulic cartridge needle valve. I said: I have no interest to develop for my peers. If you are really in a hurry, let the customer contact AAK directly. The next day, I received an email from Karl. According to the schematic diagram of the hydraulic system provided by him and the anatomical sample of the original hydraulic cartridge needle valve, as long as the pressure balance within the valve is solved and the most suitable flow area is found, this hydraulic cartridge needle valve can achieve fine pressure control. After 60 days, AAK sent 10 samples of hydraulic cartridge needle valves. Yesterday, Karl emailed us to inform that the equipment was smoothly debugged. Their engineers admired AAK's idea for the precise pressure control of the hydraulic cartridge needle valve. AAK hydraulic cartridge needle valve has an appropriate flow area between the valve spool and the valve seat, which reduces the back pressure when the hydraulic cartridge needle valve has a large displacement, and the through-hole of the valve spool achieves pressure balance up and down the valve spool. 1. The lower part of the valve rod of the hydraulic cartridge needle valve is connected to the valve spool, and the upper part of the valve body has an axially machined orifice in which an anti rotation cylinder can be inserted. A circumferential lock is formed between the anti rotation cylinder and the valve body. 2. The spool of the hydraulic cartridge needle valve is inserted into the anti rotation cylinder and forms a circumferential lock between the cartridge and the anti rotation cylinder, with an axial sealing and sliding fit. There are oil inlet and outlet channels on the side and lower axial directions of the valve body, respectively. At the same time, a through-hole is provided on the valve spool to achieve pressure balance up and down the valve spool. 3. The valve seat is installed in the oil outlet passage and forms an axial insertion fit with the upper valve spool. The upper part of the valve spool is cylindrical, and the lower end is symmetrically provided with two V-shaped throttle ramps. When the valve spool is closed, the valve spool chamfer surface contacts the valve seat chamfer surface, which can achieve fluid cutoff. AAK hydraulic cartridge needle valve, fine pressure control, few cartridge valve manufacturer can handle it, you can also give it a try! https://www.aakindustry.com/info-detail/ne , edle-valves-aak546

In mid November, Steven from Canada left a message on the website of hydraulic cartridge valve manufacturer AAK: Can you produce hydraulic cartridge pressure control valve with 2μm precision spool? From the name Steven alone, I feel that he is not an ordinary purchaser. Most of the Steven I know are leaders. After communication, it was learned that he is the procurement manager of the company. Their colleagues have customized hydraulic pressure control valves from other hydraulic cartridge valve manufacturers in China, but the accuracy of the valve spool does not meet the standard, which has caused some delay and their engineering department is in a passive situation. Now, the procurement department is under a lot of pressure. Steven's hydraulic pressure control valve is failed in not meeting the valve spool accuracy of 2μm. As long as Steven understands how hydraulic cartridge valve manufacturer AAK produces valve spool and how to control accuracy, he will have a preliminary trust in hydraulic cartridge valve manufacturer AAK. Once he receives the hydraulic pressure control valve sample sent by AAK and the sample is recognized, Steven's trust in the hydraulic cartridge valve manufacturer AAK will be established. The production of hydraulic pressure control valve spool involves the material selection first, then rough machining, and how to achieve precision machining successfully. Precision machining requires experienced technicians and equipment with stable accuracy. For precision 2μm valve spool, AAK uses Japanese STAR CNC precision automatic lathe. Before processing, our production engineer sets the processing program for the technician, and then a professional tool setter is responsible for tool alignment. After precise positioning, the technician can proceed with the machining. That is, a process, AAK subdivides it into 3 positions, with dedicated personnel for each position, while most hydraulic cartridge valve manufacturers have 1 person for 3 positions. The STAR CNC precision automatic lathe is equipped with 24 cutting tools and adopts a dual axis layout. With one clamping, it can be processed in one go, which not only improves production efficiency but also avoids human error. The online detection function of the equipment is highly favored by technicians. During the processing, key data can be detected online in a timely manner, and the program automatically compares, providing assurance for stable accuracy. Today, we sent out 12 hydraulic cartridge pressure control valve samples, and I believe there is an additional Steven on AAK's customer list. AAK hydraulic cartridge pressure control valve, 2μm accuracy valve spool, you can also give it a try!

Aga is from Türkiye, a very shrewd customer of hydraulic cartridge valves. Earlier this year, I received an email from him saying: I saw AAK from an offline store, tried searching for AAK on Google, and then found your website. I have noticed that AAK has many customer cases that have solved the difficulties and complications of hydraulic cartridge valves. I need AAK's help: 1.Can AAK improve the response speed of the hydraulic proportional needle valve? 2.What is the control accuracy of AAK hydraulic proportional needle valve? 3.How much time and cost does it take to customize the hydraulic proportional needle valve? After communication, it was learned that a hydraulic proportional needle valve purchased from India did not match their hydraulic power unit used on ships. Due to the slow response speed of the hydraulic proportional needle valve, the equipment starts slowly. Also, due to the low control accuracy of the hydraulic proportional needle valve, the equipment operation is unstable. The Indian hydraulic cartridge valve manufacturer spent more than 3 months before and after, and has not improved it. After 2 days of internal discussion within AAK, it was necessary to make innovations in the sealing and system control of hydraulic proportional needle valves. Aga requested AAK to make samples. After 50 days, AAK sent 10 samples of hydraulic proportional needle valves. Last week, Aga sent an email to inform us that the hydraulic power unit was debugged smoothly. Their engineers were very satisfied with the response speed and control accuracy of AAK hydraulic proportional needle valve. These two functional advantages far exceeded those of the Indian hydraulic cartridge valve manufacturer. Aga privately said that the purchase of this hydraulic proportional needle valve had brought him 6 months of anxiety. He finally relaxed, and the boss also gave him a week's vacation. AAK hydraulic proportional needle valve, with high control accuracy and fast response speed, has two major advantages over its peers. 1.The valve body of the hydraulic proportional needle valve is respectively provided with a main valve hole, an oil inlet port, a oil return port, and two control oil ports and two working oil ports. The oil inlet port and the oil return port are respectively connected with the two control oil ports. 2.End caps and valve sleeves are installed at both ends of the valve hole, with a valve spool inside. The step protrusions on the valve spool form two mutually isolated chambers between the valve spool and the valve body, and the working oil ports are connected. High precision control of the hydraulic proportional needle valve is achieved by accurately controlling the flow through the chamber. 3.The valve spool is of a hollow structure, and the valve spool end cover is provided with a radial through-hole with a sensor. After the displacement detection rod of the sensor passes through the end cap, it is connected to the valve spool end cap. At the same time, a sealing ring and a grid ring are respectively arranged between the valve spool, the valve body, and the valve sleeve, providing dual protection. The advantage of hydraulic proportional throttle valve response speed comes. AAK hydraulic proportional needle valve, 2 advantages, superior to peers, you can also try it! https://www.aakindustry.com/info-detail , /needle-valves-aak545

A few days ago, someone left a message on the website of hydraulic cartridge valve manufacturer AAK asking: Hydraulic Cartridge Valve manufacturer AAK often provides solutions for someone who leave messages. They may be hydraulic cartridge valve manufacturers, which are peers of AAK, or hydraulic cartridge valve demanders, but not customers of AAK. Why AAK still do this? 2 years ago, our engineering team also raised a similar question, and I didn't know how to answer it at that time. I only asked them to do it first. Last year, neighbor Grandma Zhang, who was in her 80s, provided a standard answer to hydraulic cartridge valve manufacturer AAK. Grandma Zhang likes to dance square dance every day. She fell once 3 years ago, and her legs were not very agile as before. In addition, due to the pandemic, our community's square dance has been on hold for almost 2 years. Last year, square dance started again. Although Granny Zhang is not agile in her legs and cannot dance square dance, she has become the organizer of square dance. She has also purchased a mobile audio system worth over 20,000 yuan at her own expense, and provides audio equipment for mothers in the same community every day. She only watches and does not dance. She claims to be an admirer, and many people think that Grandma Zhang is really selfless. Grandma Zhang's husband passed away 2 years ago, and her only son settled in the United States after studying abroad, leaving her alone in the family. Grandma Zhang is worried that one day she will die and no one at home will know. If she provides a sound system for everyone, if she doesn't show up for a day, countless aunties will knock on her door. She uses the sound system service to provide herself with a guarantee of not smelly for dead at home. What a wise grandmother. This morning, before 8 o'clock, the ambulance rang in the community. It turned out that Grandma Zhang was unconscious at home and didn't deliver the sound system. The square dancing lady knocked on the door, but no one answered. The ladies felt that the situation was not normal, so they quickly called the police for help. After entering the house, they found out that the Grandma Zhang was unconscious at home, so Grandma Zhang was taken to the hospital as soon as possible. I just heard that Grandma Zhang has a stroke. Fortunately, she was sent to the hospital in a timely manner and is now out of danger. Convenience with others means convenience with oneself. Grandma Zhang helped others and saved herself. Hydraulic cartridge valve manufacturer AAK, may not be as wise as Grandma Zhang, but have long understood that being convenient to others is being convenient to oneself.

According to the financial dept this morning, there was a sample fee for hydraulic pilot-operated relief valves. I knew it was from ROQUET company in Spain. One year ago, Domingo in their company had a hydraulic pilot-operated relief valve that needed AAK to make samples, but was unwilling to pay $2,000 of the sampling fee. The original factory didn't need them to pay, so they chose that factory to produce this hydraulic pilot-operated relief valve. Last week, Domingo came to me again to ask if there was time for sampling and they would pay the sampling fee. After communication, it was learned that the hydraulic pilot-operated relief valves shipped by the original factory were used in the hydraulic power unit. Less than half a year, it was reported for repair by the customer. It is easy to have insufficient power supply of the hydraulic system during the construction process. The after-sales engineer found that the wear of the valve spool of the hydraulic pilot-operated relief valves led to leakage. He had to use the alternative pilot-operated relief valves first and asked Domingo to contact the original manufacturer to solve the problem. The original manufacturer reported that the hydraulic pilot-operated relief valves had not been worn for more than 1 year previously. The working pressure is more than 450bar this time. The domestic hydraulic pilot-operated relief valves can only have a service life of half a year. If you want to find a hydraulic pilot- operated relief valve with a service life of more than 1 year, you can only buy it from HAWE in Germany. They are the best manufacturer of hydraulic pilot- operated relief valves with high pressure resistance in the world, but the price is estimated to be more than twice that of Chinese manufacturers. Domingo was a little helpless and asked the boss whether to purchase directly from HAWE in Germany or continue to look for hydraulic pilot-operated relief valve manufacturers in China. Because the alternative hydraulic pilot-operated relief valves were used on the construction site, they still had a 6-month buffer period. The boss asked him to look for the hydraulic pilot-operated relief valves under high pressure at the same time. At this moment, he thought of AAK. When I told him that the key point of the service life of this hydraulic pilot-operated relief valve is to resist high pressure, AAK has an engineer who has worked in HAWE Shanghai factory for 8 years, our production of high-pressure hydraulic valves is just to benchmark with that of German HAWE company, he seems to realize that perhaps AAK can sample a hydraulic pilot- operated relief valve with a service life of more than 1 year this time. AAK replied that it could complete the samples of 12 hydraulic pilot-operated relief valves within 1 month, and the warranty was more than 1 year. Domingo remitted the sample fee of US$2,000 the next day. I asked him why he was unwilling to pay last time, but this time he immediately paid the sample fee of the hydraulic pilot-operated relief valves. He was frank about two points. First, AAK mentioned the key points for the success of the sample. Second, AAK high-pressure hydraulic pilot-operated relief valves benchmarked with German HAWE company. The reason why AAK can tell the key points and why it can benchmark with German HAWE company is that there are two key points of AAK pilot-operated relief valves. It may be difficult to find the second manufacturer of hydraulic valves in Ningbo. 1. The valve spool of AAK pilot-operated relief valve is ETG100 produced by STEELTEC company of Switzerland, which is easy to cut and has high strength. It is suitable for high-speed CNC processing, and the strength of each section inside and outside the material is consistent. After the valve spool is processed into shape, the strength will not be affected. 2. AAK has a high-precision CNC machining center imported from Switzerland. After the engineers set the program, they can control the steel processing efficiently and without mistakes. Not only the strength is not affected, but also the accuracy is guaranteed. AAK hydraulic pilot-operated relief valve is used for working pressure above 450bar. You can also have a small try! https://www.aakindustry.com/info-detai , l/hydraulic-pilot-operated-relief-valves- aak20 , 7

Camden is from a hydraulic equipment company in Sweden and has been engaged in procurement for 2 years. One of their customers ordered 2 sets of customized hydraulic power units, and specially reminded that the working environment of the equipment is 20 ℃ below zero. The hydraulic power unit is required to be durable for at least 1 year, and its stability should be the first. Their engineer suggested purchasing SUN hydraulic cartridge counterbalance valves, but the parameters of SUN standard parts could not fully meet the requirements of equipment working conditions, and there is no enough quantity and time to customize SUN hydraulic cartridge counterbalance valves. Camden contacted a local manufacturer of hydraulic cartridge counterbalance valves, and the manufacturer was willing and confident to sample. 3 months later, the customer complained that the equipment was not stable enough, but it was barely usable. 6 months later, the equipment went on strike. During after sales service checking, it was found that the control of the hydraulic cartridge counterbalance valve was abnormal. The original manufacturer was surprised and confused. After disassembling the hydraulic cartridge counterbalance valve, it was found that the installation torque was too large, which could easily cause the valve to jam, and there were also abnormal seals, the original manufacturer had to surrender. Camden tried to find a new manufacturer of hydraulic cartridge counterbalance valve. After a week, it was fruitless. The boss blamed Camden for poor procurement. Camden noticed AAK at Google and found that AAK Hydraulic Valve is SUN's supplier of hydraulic components for 5 consecutive years. He left a message: SUN is unwilling to sample a hydraulic cartridge counterbalance valve, and AAK is able to do a good job? The hydraulic cartridge counterbalance valve shall be durable for not less than 1 year, and its stability shall be guaranteed. I have judged that he is in trouble when purchasing hydraulic cartridge counterbalance valves. According to the hydraulic schematic diagram of the system, hydraulic cartridge counterbalance valve drawings, equipment working condition parameters and working scenarios provided by Camden, AAK engineer found that this hydraulic cartridge counterbalance valve is similar to the hydraulic cartridge relief valves that we supplied to a Russian customer 1 year ago, which had a service life of at least 1 year under extremely cold conditions of - 55 ℃. Camden was very happy to learn about the similar customer case of AAK, and requested to customize the hydraulic cartridge counterbalance valve and benchmark SUN. I said that AAK does not pursue whether this hydraulic cartridge counterbalance valve is advanced, but it must benchmark SUN in stability and reliability. At the same time, AAK needs to redesign this hydraulic cartridge counterbalance valve from 3 aspects. After 45 days, AAK hydraulic cartridge counterbalance valve samples were sent. 3 months later, Camden emailed us that yesterday, the customer reported that the stability of the hydraulic power unit with new hydraulic cartridge counterbalance valve was much better than that of the last time. If there was no abnormality within 1 year, the purchase of equipment would be increased. I told him that the AAK hydraulic cartridge counterbalance valve, which has no worries for 1 year, has 3 main highlights: 1. The installation torque of hydraulic cartridge counterbalance valve designed by peer is too large, which will affect the valve spool and control piston, causing valve jamming. The hydraulic cartridge counterbalance valve designed by AAK, the inserts form a snap floating connection with the valve body, and a seal connection with the valve cage to avoid jamming. 2. AAK sets a throttling slot between the pilot valve spool and the main valve spool, to achieve stable control pressure at the pilot port, with mild changes in the opening phase. During the control load drop, the main valve spool opening is not affected by the load pressure. 3. AAK makes the outer diameter of the pilot mechanism of the hydraulic cartridge counterbalance valve into a ladder shape, avoiding possible leakage caused by cutting of the seal ring, and increasing the service life by at least 20%. AAK hydraulic cartridge counterbalance valve, 3 highlights, no worry in at least 1 year of use, you can also have a small try! https://www.aakindustry.com/info-detai , l/hydraulic-cartridge-counterbalance- valves-aa , k400
