AAK Hydraulic Flow Control Valve with 3 major advantages, recognized by Yagmur Yagmur is from T�¼rkiye and mainly purchases hydraulic cartridge valve standard parts from Ningbo. Recently, they developed a hydraulic drilling equipment that uses hydraulic flow control valves that are modeled after HydraForce standard parts, and purchased from a hydraulic valve manufacturer in Ningbo. During equipment debugging, it was found that the flow rate of the hydraulic flow control valve was unstable, and the leakage rate did not match the hydraulic system. The original hydraulic flow control valve manufacturer stated that this is a replica of HydraForce and is unwilling to optimize its function for several hydraulic flow control valve samples. Yagmur checked with several other hydraulic valve manufacturers, but they were not interested. Yamour was very anxious. The original hydraulic flow control valve manufacturer introduced AAK to Yagmur. After communication, it was learned that her requirements for this model include low leakage and high precision requirements for valve holes. Based on the hydraulic system schematic provided by her and the industry model code of the HydraForce hydraulic flow control valve, I recommended a ready-made sample to her. As long as the external dimensions meet his manifold requirements, it can solve the problem she is currently facing. 2 weeks after the sample was sent out, Yagmur informed via email that the drilling equipment was successfully debugged. The low leakage of AAK hydraulic flow control valve meets their system requirements, especially the flow control function that they are very satisfied with. I told her that for this AAK hydraulic flow control valve, we have 3 major advantages: 1. The internal leakage of AAK hydraulic flow control valve is 5 drops/min, while most peers can only achieve 8-10 drops/min. 2. The hole accuracy of AAK hydraulic flow control valve can reach IT6-IT7 level, and the surface roughness can reach Ra0.2-0.025m. 3. The AAK hydraulic flow control valve function fully aligns with the standard parts of HydraForce, and there are probably no more than 3 manufacturers in Ningbo to meet it. The vast majority of hydraulic flow control valve manufacturers in the industry do not use forming cutters for machining small quantities of hydraulic flow control valves, but use CNC instead to process according to dimensional requirements. The result of this machining is an accuracy of 0.03mm and a positional tolerance of 0.02mm. The AAK hydraulic flow control valve is processed with forming tools, and the dimensional accuracy of the valve hole after processing reaches 0.01mm, with a positional tolerance within 0.007mm. At the same time, AAK has its own standards for tool selection, with hardness of HRA90 alloy material, heat resistance of 900 , valve hole accuracy of IT6-IT7 level, surface roughness of Ra0.2-0.02m, and tool life is 30 times higher than ordinary alloy steel.
For Pilot-Operated Pressure Reducing/Relieving Valve equivalent to SUN PPDB-LDN, AAK received the re-peat order from customer in Europe Last April, we shipped a Pilot-Operated Pressure Reducing/Relieving Valve equivalent to SUN PPDB-LDN to a customer in Europe. Yesterday, we received a re-peat order of 500 pcs for this valve. This is really great news for us, because it means that the quality of E-PPDB-LDN Pilot-operated, pressure reducing/relieving valve shipped by AAK has been approved by this customer, and AAK is getting another customer in Europe. The advantages of this pilot operated pressure reducing/relieving valve are: 1. The quality of this valve is benchmarking SUN Hydraulics, but price is much cheaper. 2. The service life is 2 times that of domestic hydraulic cartridge valve manufacturers in China Technical parameters of AAK E-PPDB Hydraulic Pilot-operated, pressure reducing/relieving valve: Max. Operating Pressure: 350 bar (5000 psi) Capacity: 10 gpm (40L/min) Control Pilot Flow: 7 - 10 in�?�³/min.

For hydraulic cartridge flow control valve with 2m accuracy, hydraulic cartridge valve manufacturer AAK has 3 details to meet it Last week, Akjoor from T�¼rkiye left a message on the website of the hydraulic cartridge valve manufacturer AAK: I need the lead time of producing a standard hydraulic cartridge flow control valve, but the precision of the valve cage must be controlled within 2m. After communication, we learned that Akjoor purchased 360 pcs of hydraulic cartridge flow control valves from another hydraulic cartridge valve manufacturer. Except for the unstable valve cage accuracy, all other functions meet the requirements of their engineers. This hydraulic cartridge flow control valve is actually not difficult, with a valve cage accuracy of within 2m is an additional requirement of Akjoor. Most hydraulic cartridge valve manufacturers are only able to copy standard parts. If there are additional requirements, stability can be a problem. I sent Akjoor a video of hydraulic cartridge valve manufacturer AAK produced hydraulic cartridge flow control valve cages last time, showing how AAK controlled the accuracy of the valve cages in 3 steps. The machining of AAK hydraulic threaded cartridge valve cage is carried out using Jidou fully automatic lathe, which is suitable for machining parts with precision requirements. After one clamping, the machining of the valve cage is completed in one go. 1. After the valve cage clamp is completed, check the positioning to ensure that the clamp is fixed without deviation, then close the safety door and start processing. 2. After the valve cage is processed, the technician takes out the valve cage and uses an air gun to remove debris from the valve cage and fixture. 3. Use a plug gauge to check the machining size of the valve cage. Today, we received the test order from Akjoor, but need to start production after CNY, because our workshop has already been closed due to CNY holiday. AAK hydraulic cartridge flow control valve, 3 details, no problem to meet 2m accuracy. AAK HYDRAULIC CARTRIDGE VALVES (775) 2024-02-05
For Hydraulic Flow divider/combiner valve equivalent to HydraForce FD50-45, AAK received the trial order from a Customer in the United States This week, weâ??d like to introduce a hydraulic flow divider/combiner valve equivalent to HydraForce FD50-45. This valve is a screw-in cartridge, spool type flow divider/combiner valve. It provides pressure compensated proportional division of inlet flow or combining of two return flows regardless of system operating pressure conditions. The valve provides synchronizing flow in dividing and combining modes. The valve is intended for use in mineral based or synthetic hydraulic fluids with lubricating properties. Last December, we received an inquiry from a new customer in the United States for HydraForce FD50-45 Hydraulic Divider/Combiner valve. This cartridge valve is not very commonly used, and there are only a few hydraulic cartridge valve manufacturers in Ningbo China that have this model in stock. Per customer, they have followed up hydraulic cartridge valve manufacturer AAK for a long time, and would like to place a trial order for 10 pcs for HydraForce FD50-45 first. If the valves passed testing, they will place the annual order for 1,000 pcs. We are confident to become the preferred hydraulic cartridge valve supplier for this customer in the United States, because AAK quality has been approved for many American customers. AAK hydraulic Flow divider/combiner valve: 1. The function and performance is equivalent to that of HydraForce FD50-45 2. Its service life is longer than of its domestic peers Technical parameters of AAK E-FD50-45 hydraulic Flow divider/combiner valve: Max.

This week, weâ??d like to introduce a hydraulic pilot-to-close check valve equivalent to SUN COFA, a spring biased closed, pilot-to-close check cartridge that has a 1.8:1 pilot ratio. Last October, we received an inquiry from a new customer in the United States for SUN COFA Pilot-to-close check valve. This cartridge valve is not very commonly used, and there are only a few hydraulic cartridge valve manufacturers in Ningbo China that have this model in stock. Per customer, they placed the trial orders with 3 manufacturers, and will do durability testing at the same time. The one who has the best performance in the testing will be their preferred supplier. Last month, we received the good news from the customer that AAK samples passed the durability testing for 2 million times, and the price is in the middle among 3 manufacturers. But the manufacturer who has the lowest price did not pass the durability testing for 2 million times. They will choose AAK their preferred supplier for hydraulic screw-in cartridge valves. AAK hydraulic pilot-to-close check valve E-COFA two advantages: 1. The function and performance is equivalent to that of SUN COFA 2. Its service life is longer than of its domestic peers Technical parameters of AAK E-COFA hydraulic pilot-to-close check valve: Max.

For 2¼m precision hydraulic pressure control valve, AAK uses American Hardinge CNC machine tool Last week, we mentioned that the hydraulic directional control valve cage of Ra0.8 and roundness tolerance of 1�¼m, a customer Jhon from Mexico left a message to us: Can AAK produce hydraulic pressure control valve with valve cage accuracy within 2�¼m? Many hydraulic cartridge valve manufacturers in China are not very focused on the accuracy of valve cages because the domestic market is used to it. It is not very difficult to produce the hydraulic pressure control valve with cage accuracy within 2�¼m. We have similar customer requirements, whether it is for hydraulic directional control valves, hydraulic pressure control valves, or hydraulic flow control valves. We will select suitable machine tools for production based on the production situation in the workshop and customer requirements. When new customers ask if AAK can achieve any precision or specific requirements for hydraulic cartridge valves, this is an opportunity for hydraulic cartridge valve manufacturer AAK, as it is highly likely that customers have encountered difficulties with other hydraulic cartridge valve manufacturers. For Jhon's message, I sent him a video, which may be more convincing. Although he received our video on Monday and did not reply on the same day, I believe he will send an inquiry. For hydraulic pressure control valves with cage accuracy within 2�¼m, AAK can choose the Hardinge CNC machine tool from the United States as shown in the video. The overall structure adopts a 45 �° inclined bed. When we installed it, we filled the equipment cavity with marble. The advantage of this is that it avoids the occurrence of small vibration lines on the surface of the workpiece due to the impact of vibration waves on the continuity of the tool during the cutting process, which affects the accuracy of the valve cage. From the video, it can be seen that the entire cutting process is carried out in a stable and almost vibration free condition. The machine tool is also equipped with 20 knives and can produce hydraulic pressure control valves of different models. Today, we just received an inquiry from Jhon for a hydraulic pressure control valve with drawings, hoping that we can secure another customer from Mexico. AAK hydraulic pressure control valve, valve cage accuracy within 2�¼m, you can also try a small order! AAK HYDRAULIC CARTRIDGE VALVES (770) 2024-01-30
For Hydraulic Counterbalance Valve Valve equivalent to SUN CBGG, a Spain customer placed the annual order after 15 months finally This week, weâ??d like to introduce a Hydraulic Screw-in Counterbalance Valve equivalent to SUN standard part CBGG. The counterbalance valves with pilot assist are meant to control an overrunning load. The check valve allows free flow from the directional valve (port 2) to the load (port 1) while a direct-acting, pilot-assisted relief valve controls flow from port 1 to port 2. Pilot assist at port 3 lowers the effective setting of the relief valve at a rate determined by the pilot ratio. A customer in Spain sent us inquiry for this counterbalance valve last September, with annual qty of 600 pcs. However, after we quoted the price, there was no any feedback. The customer sent us inquires for other SUN cartridge valves at later times. Every time, there was no any feedback. Unexpectedly, this March, the customer got back to us and placed the trial order of 10 pcs for CBGG. Until that time, we learned that AAK prices were 5% - 10% higher than other hydraulic cartridge valve manufacturers in China every time, so he placed the orders with other manufacturers. However, the quality of hydraulic cartridge valves he purchased from other hydraulic cartridge valve manufacturers in Ningbo was not stable, he was very frustrated, so he wanted to test AAK quality. We delivered the 10 pcs of test samples. Last week, we were very happy to learn that AAK samples passed the testing. They are still performing very well after 9 months of use. The customer placed their annual order with AAK finally. It has been 15 months since we received the inquiry for this counterbalance valve CBGG. AAK hydraulic counterbalance valve 2 advantages: 1. Function and Performance benchmarking SUN 2. Its service life is 2 times that of its domestic peers Technical parameters of AAK E-CBGG Hydraulic Counterbalance Valve: Max. Operating Pressure: 350 bar (5000 psi) Flow: 240 L (60 gpm) Internal Leakage: 5 drops/min Pilot Ratio: 4.5:1 Temperature: - 30 to +100 �°C (with Standard Buna N seals) Cavity: T-17A Fluids: Mineral based or synthetic hydraulic fluid with lubricating properties Fluid Viscosity Range: 7.4 to 420 cSt AAK E-CBGG hydraulic counterbalance valve, equivalent to SUN CBGG, and the service life is 2 times of its domestic peers. You are welcome to try an order with us.
The original manufacturer cannot handle RV12-26 hydraulic pressure control valve with special requirements, and AAK solved it with 2 strict processes A few days ago, Anthony from Spain needed to purchase a hydraulic screw-in cartridge pressure control valve equivalent to HydraForce RV12-26, but with a special requirement for the accuracy of the valve cage. Anthony chose a hydraulic cartridge valve manufacturer in Ningbo China who had cooperated with him for 2 years. However, the accuracy of the valve cage for RV12-26 hydraulic pressure control valve was unstable. The original manufacturer made samples for 3 times and all failed. 2 months have been wasted, and the engineer was very dissatisfied. Anthony was very frustrated. Last week, Anthony browsed the website of AAK hydraulic cartridge valve manufacturer on B2B and left a message: 1. Do you have procedure for RV12-26 hydraulic screw-in cartridge pressure control valve? 2. Can the valve cage of hydraulic pressure control valve be customized with special requirements? 3. Can you ensure that the valve cage of each hydraulic pressure control valve meets the accuracy requirements? After communication, we learned that Anthony encountered a problem with the accuracy of the hydraulic pressure control valve cage when purchasing from the original hydraulic cartridge valve manufacturer. In response to his special requirements, we provided 2 suggestions: optimizing the precision machining of the valve cage and conducting 100% independent testing of the valve cage accuracy. Anthony asked, how does AAK detect the accuracy of valve cages? First, I told Anthony that accuracy is not determined by testing, but rather by precision machining. For valve cage with special requirements, focus on precision machining only cannot avoid potential problem completely. At this point, testing is to eliminate the hidden problem, and the original hydraulic cartridge valve manufacturer may have overlooked this detail. The valve cage of this hydraulic pressure control valve can be precision machined using the TOYODA cylindrical grinder from Japan. The stable grinding accuracy is the best among our experienced technicians, not only high in accuracy, but also stable. Especially low vibration bed and high-precision feed mechanism, combined with specialized cutting fluid, the processed hydraulic pressure control valve cage has a clear contour and a surface finish of within Ra0.2�¼m, the dimensional accuracy tolerance is within 0.5�¼m. Regarding the inspection of the hydraulic pressure control valve cage, please refer to the video of our workshop's on-site operation. This is a KEYENCE measuring instrument imported from Japan, which is equipped with a 20 megapixel CMOS laser probe. Before testing, our QC first inputs the size requirements of the valve cage into the program, then places the valve cage into the platform.
Distinguished between assumptions and attributions, hydraulic manifold manufacturer AAK focuses on 3 points for online business This year, China's foreign trade data is not impressive, and it seems that the export of hydraulic manifold manufacturers to overseas markets has also been affected. A while ago, colleagues from Ningbo hydraulic manifold manufacturers had a salon where they analyzed the reasons for the foreign trade situation and made attribution. Hydraulic manifold manufacturer A said that the overall consumption environment is not good, and customer procurement demand has declined. Hydraulic manifold manufacturer B said that the price has not been recognized by the market and a more competitive price is needed. Hydraulic manifold manufacturer C said that the quality of the product is not recognized by customers and there is a need to improve the manufacturing quality of the hydraulic manifolds. In summary, either the price is high, the quality is poor, or the customer purchases less, so the export of hydraulic manifold manufacturers to overseas markets has also been affected. However, have you noticed that many times, what we summarize is not one attribution after another, but one hypothesis after another. To challenge all unverified assumptions and increase the overseas exports of hydraulic manifold manufacturers, we must first understand why business has declined. That is to say, correct attribution. Attribution is a truth that has been verified to be true, false, and logical. And assumption is a possibility based on past experience and probability. Only when hypotheses have been verified one by one can they become attributions. Directly attributing assumptions can result in fatal consequences. All unverified hypotheses should be challenged at least once. Many times, our assumptions are wrong. And these sounds were originally not difficult to hear. It is because of excessive belief in assumptions that all attributions are isolated from the wall. If hydraulic manifold manufacturers spend more time getting close to customer engineers, perhaps they can find the correct attribution. This is also why hydraulic manifold manufacturer AAK prefers to do online business rather than traditional models, for which as long as the buyer is secured, while online business not only requires stable hydraulic manifold manufacturing quality, but also daily communication, trust building, and interaction with customer engineers. Only such a three-point triangle is stable. Hydraulic manifold manufacturer AAK, focuses on 3 points and insists on doing online business. AAK HYDRAULIC VALVES (733) 2023-12-10
The unfamiliar customer we met for the first time, hydraulic manifold manufacturer AAK, brought him 3 values A top 3 hydraulic manifold importer in the United States, has been purchasing from a hydraulic manifold manufacturer in Ningbo China for 3 years. I met their procurement director Steven 2 years ago, but he did not know me. Last October, I learned that Steven had come to Ningbo, and I wanted to get to know him and introduce hydraulic manifold manufacturer AAK to him. I waited in the lobby of the hotel for over 3 hours, and when I saw Steven returning, I politely greeted him and presented my business card. I also briefly introduced the hydraulic manifold manufacturer AAK, and Steven replied gentlemanly, "I have your business card, so you can go back early.". At this point, if I say goodbye, it's estimated that the business card of hydraulic manifold manufacturer AAK will be in the trash can. On the road of business, do people, from strangers to acquaintances, essentially make use of each other? When you are valuable in front of others, some things are easy to talk about. I answered this way at the time: Thank you Steven for giving me a few minutes. I will say goodbye soon, but you need to keep this business card because it is very valuable to you. Steven shook the business card and asked with a smile, "What value does it have for me? You can talk about it.â?? I told him that there are 3 values. I know you have been purchasing from that hydraulic manifold manufacturer in Ningbo China for 3 years, and this hydraulic manifold manufacturer is also good. From the selection of suppliers, it can be seen that you are professional, which is why I came to visit you. I don't say that hydraulic manifold manufacturer AAK is better than your supplier, but at least not worse than him. For you, if there are any issues with the original supplier, hydraulic manifold manufacturer AAK is your best alternative option, so the first value that hydraulic manifold manufacturer AAK brings to you is safety. In the hydraulic manifold industry, hydraulic manifold manufacturer AAK is synchronized with your supplier. If you only cooperate with this one company, then there is a lot of information in this industry, and perhaps you only know half of it. With hydraulic manifold manufacturer AAK as a supplement, you are basically familiar with the information in this industry. If your boss wants to ask, how do you think about the development of this industry and how to adjust your procurement ideas in the future, you can have more comprehensive information. So the second value brought by hydraulic manifold manufacturer AAK is information value. The third value, if your supplier knows that hydraulic manifold manufacturer AAK is contacting you and he is also a bit nervous, perhaps he will treat you better, so the third value brought by hydraulic manifold manufacturer AAK is chip value.

The original manufacturer was unable to meet the valve hole requirement for the hydraulic valve block, and Caltha returned to AAK 2 months later Caltha is from Mexico and has been purchasing hydraulic valve blocks in Ningbo China for 5 years. AAK is also one of his suppliers of hydraulic valve blocks. At the beginning of this year, their old buyer left the company and Caltha began to be responsible for the procurement of hydraulic valve blocks. The first inquiry I received from Caltha was for hydraulic valve blocks. A week later, Caltha informed AAK that the price was 17% higher and she chose another hydraulic valve block manufacturer in China. Upon seeing this big price difference, I had to give up. 2 months later, Caltha emailed me asking if the hydraulic valve blocks quoted at the beginning of the year could be completed for 5 samples within 25 days. I felt Caltha's anxiety, and after communication, I learned that the hole accuracy of the hydraulic valve block produced by the original manufacturer was not up to standard. However, the manufacturer blamed some valve hole accuracy deviations on being normal, and using electric sealant could solve the leakage. Caltha didn't want to take any risks and came back to AAK I can understand Caltha's emotions, after all, their company is a loyal customer of AAK. Our technical team started to decompose the hydraulic valve block drawings immediately. Within 25 days, AAK sent 5 hydraulic valve block samples. 2 weeks later, Caltha informed AAK that their hydraulic manifold had been tested successfully. She asked me to wait for the batch order of hydraulic valve blocks. The processing of hydraulic valve block valve holes that the original manufacturer cannot handle mainly depends on the selection of equipment and the control of accuracy. The processing of this AAK hydraulic valve block adopts the Taikan Group Processing Center, which has 3 major advantages: 1. The machining is stable, and its spindle structure adopts high-quality mihanna cast iron, with stable movement. For the same batch of hydraulic valve blocks, using the same tool and processing program, the motion trajectory of the tool is the same, and its CNC program achieves computer control, which can avoid human error. Most hydraulic valve block manufacturers do not choose this equipment. 2. High precision. The valve hole accuracy is within 0.005mm, and the repeated positioning accuracy can reach 0.003mm, and precision correction and compensation can be carried out simultaneously using CNC software. 3. High production efficiency. The spindle speed can reach 24000 RPM, and it also has functions such as automatic speed change, automatic tool change, and other auxiliary operation automation. Compared to ordinary machine tools, the production efficiency is 3-4 times higher. AAK hydraulic valve block, fast processing, and guaranteed accuracy, you can also give it a try!
The Peddler selling sweet potatoes taught a lesson to Chinese Solenoid Valve Manufacturer AAK, who realized that help is selfless On the way home from work on Friday, I saw someone selling sweet potatoes, which suddenly reminded me of the story I had with a sweet potato peddler last winter. I remembered one particularly cold day last winter, a Chinese person from Shanghai came to Ningbo to source for a Chinese solenoid valve manufacturer for an American customer. AAK was his first stop, and the meeting lasted a long time. It wasn't until 5:30 pm that he left with satisfaction. I walked out of the factory and felt extremely cold outside. At this moment, I received a call from my wife, who said that it was particularly cold outside today and asked me to come back early. Dinner was already ready. I was very happy when I received this call, thinking that the steaming dinner at home was waiting for me, so I hurried home. On the way home, I found a person standing by the roadside. In front of him was a round stove with a pile of sweet potatoes on it. It turned out to be a peddler selling sweet potatoes while roasting sweet potatoes. I can see that he is shivering in the cold wind, but not many of these piles of sweet potatoes have been sold. I thought to myself that his task for today has not been completed yet, and the benefits for the day have not yet been realized, so he must persist here. And I, on the other hand, can immediately return home and have that steaming dinner. By comparison, compassion arose naturally. I bought 8 sweet potatoes from him in one go, and I thought to myself, if I buy one more sweet potato from him, I can make him go home earlier. I bought 8 sweet potatoes and went home with a sense of satisfaction along the way. There's nothing wrong with this sense of satisfaction, after all, I did a moral kindness and helped him. But I also have a sense of superiority, I thought to myself, after all, I am a small boss of a Chinese solenoid valve manufacturer, he is just a peddler. I returned home with this sense of satisfaction and superiority. Sitting down at the dining table, I remembered the peddler selling sweet potatoes and suddenly realized that my realm was very low. I helped him, in Buddhism, it's called giving. When I was giving to this peddler, I had a sense of superiority that was condescending. This kind of help was very self-centered and not selfless. People need to help each other, but when you help others, don't think you are one level higher than the person being helped. If I, a small boss of a Chinese solenoid valve manufacturer, urgently need help in a special occasion in the future, and in this occasion, perhaps a peddler helped me selflessly. When the peddler gives me a helping hand, if he is very self-centered, he won't help me. So I understand that the peddler selling sweet potatoes is certainly shivering in the cold wind of nature. In fact, I, a small owner of a Chinese solenoid valve manufacturer,
Our old Greek customer, Evander, emailed me in November last year that he sent me a sample of hydraulic cartridge relief valve, and stressing that it was not his, but one of his partners, Ptolemy, and also attached Ptolemy's contact information. After receiving the sample and communicating with Ptolemy, we learned that the hydraulic cartridge relief valve was produced by a local cartridge valve manufacturer in Greek and installed in their hydraulic cylinder, which was unstable. Their engineers said that the root cause was the high back pressure of the hydraulic system and the insensitive opening of the hydraulic cartridge valve. We can't determine the hidden dangers of the hydraulic cartridge valve just according to the original sample. I suggested Evander sending us the video of abnormal hydraulic cylinder, the drawing of hydraulic cartridge valve, and the schematic of the system. After discussing, AAK engineers advised that the problem can only be solved by reducing the opening back pressure resistance of the hydraulic cartridge valve. Perhaps because of Evander's endorsement, Ptolemy paid the development fee on the second day. I have always believed that for industrial products such as hydraulic cartridge valves, it is difficult to get the order without trust. With trust and reliable manufacturing quality, it is easy to get the order. After 40 days, AAK sent 20 samples of hydraulic cartridge valve. Yesterday, Ptolemy emailed me that AAK hydraulic cartridge relief valve was used on the hydraulic cylinder. The prototype operated stably and the hydraulic cartridge valve opened sensitively. AAK hydraulic cartridge valve is stable and sensitive under high back pressure. We optimized the structure of the original hydraulic cartridge relief valve from 3 aspects. 1. The valve sleeve of the hydraulic cartridge relief valve has an oil inlet cavity, and the outer circle of the valve sleeve is provided with a plurality of annular through holes as oil outlet, and oblique holes are set to control the oil outlet. 2. The middle part of the main valve spool is provided with a small hole connecting the oil inlet cavity and the inclined hole, and the main valve spool can slide in the valve body to form a spring cavity that is relatively closed to the oil inlet cavity, and the spring cavity is equipped with a pressure regulating spring. 3. The left end of the valve body is installed with an adjustable rod that can be rotated and retracted and has a lock nut. The pressure regulating spring on the adjusting rod is connected to the main valve spool. The outer diameter of the right end of the valve body is provided with a sealing groove to place the sealing ring group. Two sealing grooves are set on the left side of the external thread of the valve body, and the sealing ring group is placed to seal the connection with the socket to prevent oil leakage. The optimized AAK hydraulic cartridge relief valve equalizes the pressure difference
AAK Hydraulic Cartridge Relief Valve, helped Monroe promoted to purchase manager Monroe is from Turkey, and has cooperated with AAK for 3 years. He purchases cartridge valves equivalent to HydraForce standard parts 3-5 times a year. Some time ago, he emailed me to ask: Can you customize non-standard parts of hydraulic cartridge relief valve? I was a little surprised because there was no inquiry for non-standard cartridge valves in the past 3 years. After communication, it was learned that the hydraulic cartridge relief valve used in one of their hydraulic cylinders encountered a problem. The vibration of the oil cylinder was severe, and the problem came from the hydraulic cartridge relief valve, which was slow in response to overload and overflow. This cartridge relief valve was customized from a hydraulic cartridge valve manufacturer in Ningbo. The manufacturer had optimized it twice, but the improvement was not obvious. I asked him if as long as the hydraulic cartridge relief valve is sensitive to overload and overflow, it can solve the problem of cylinder jitter. I was just afraid to waste his sample time. After getting the approval of their engineer, according to his system schematic diagram and the original drawing of the hydraulic cartridge relief valve, AAK engineer judged that after change the pilot function of the original hydraulic cartridge relief valve, it can react sensitively. After 35 days, AAK sent 8 samples of hydraulic cartridge relief valves. During the CNY, he sent us a PO of 280 hydraulic cartridge relief valves. He said that the cylinder fitted with AAK hydraulic cartridge relief valve very well, and did not shake. The customer was very satisfied with the trial of the cylinder, and placed the order with them for the cylinder. AAK hydraulic cartridge relief valve is sensitive to overload and overflow. The key is that we have made 3 breakthroughs in valve spool, seat structure and sealing. The optimized AAK hydraulic cartridge relief valve strengthens the pilot function, and can directly push the valve spool to release pressure without opening the pilot structure first. In the overload of hydraulic cartridge relief valve, the overflow action is more direct and sensitive. 1. Change the through-hole of the oil replenishing valve spool of the hydraulic cartridge relief valve to be larger than the cross-sectional area of the valve seat opening, and the oil replenishing valve spool and the overflow valve spool are arranged coaxially, and the pressure regulating screw is connected with the pressure regulating lock nut through the thread. 2. One end of the oil inlet of the valve seat is connected with the rear through-hole of the oil filling valve spool, and is equipped with a sealing ring and a spring. 3. The left end of the valve seat is the clamping part, the middle and front parts are the plug-in parts which are similar to the cylinder structure,
has purchased hydraulic valves from for 6 years, and has cooperated with in several non-standard hydraulic cartridge valves. Some time ago, some customers complained that their logistics transmission equipment was not easy to operate. After the after-sales inspection, it was found that the hydraulic cartridge relief valve on the rotary device failed to buffer and the pressure regulation was not smooth. The original manufacturer said that this hydraulic cartridge relief valve was benchmarked to the standard parts of HydraForce, and he was unable to optimize. contacted me and asked me how to make the hydraulic cartridge relief valve easy to adjust pressure and have buffering function. According to the hydraulic schematic diagram and the original hydraulic cartridge relief valve drawing provided, engineer found that the requirements can be met as long as the original structure is improved. After 35 days, sent 20 samples of hydraulic cartridge relief valves. Last week, Clinton sent a PO for 200 hydraulic cartridge relief valves. He said that when hydraulic cartridge relief valve was installed, the customer no longer complained. It not only provided convenient pressure regulation and effective buffering, but also improved the stability of the equipment. They planned to replace the whole batch of equipment with hydraulic cartridge relief valves. hydraulic cartridge relief valve, the spool, buffer piston and pressure regulating valve housing cooperate to achieve buffer overflow effect, and the overall performance is reliable and stable, mainly from 3 unique structures: 1. The valve housing is provided with a first oil port, and the valve seat is provided with a second oil port. The valve spool can move axially, and the front end cooperates with the rear port of the valve seat to control the on-off between the second oil port and the first oil port. The channel port in the front end of the valve spool is provided with a plug, and the plug is axially provided with a damping hole. The front end face of the valve spool is equipped with a filter screen, and the front pressure surface of the valve spool is larger than the rear pressure surface. 2. The inner cavity of the front end of the pressure regulating screw nut has a buffer piston, and the rear end has a guide part. The radial bulge in the middle forms a convex ring part. The axial opening in the front end matches with the rear end of the valve spool. The oil supply in the middle of the convex ring part is with the connecting channel outside the rear end. 3. The pressure regulating screw is hollow at the rear end of the valve spool to form an inner cavity, which can move axially and change the axial force of the spring. The inner cavity wall of the front end of the pressure regulating screw is matched with the front end face of the convex ring to limit the buffer piston to move forward.
