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.
Dual-function Hydraulic Cartridge Proportional Needle valve, AAK customized part replaced HydraForce standard part Devante is from a Spanish hydraulic equipment manufacturing company, and has been engaged in procurement for more than 5 years. Last February, they upgraded an injection molding machine, focusing on the selling point of "high speed when empty, low speed when heavy load". The engineer asked Devante to purchase the hydraulic cartridge proportional needle valve of HydraForce. During the equipment commissioning, it was found that the pressure relief and flow of the hydraulic system of the equipment was conflicted with the hydraulic cartridge proportional needle valve, resulting in unstable operation of the equipment and jitter. HydraForce said that there was no time to customize the hydraulic cartridge proportional needle valve. Devante contacted several cartridge valve manufacturers and had no news. Devante was very worried. Devante browsed AAK website on Google and left a message: 1. Can AAK customize the hydraulic cartridge proportional needle valve, and the performance benchmarking HydraForce? 2. The function of smooth flow passage is required. 3. The function of variable flow gain is required. At the beginning, I thought that he was requested for AAK hydraulic cartridge proportional needle valve to benchmark the standard parts of HydraForce, but it was turned out that he needed us to optimize the standard parts of HydraForce. According to the equipment abnormality video, the original hydraulic cartridge proportional needle valve drawing, and their required functions sent by Devante, after discussion, AAK engineers was 90% confident. Devante asked AAK to make samples. After 40 days, AAK sent 15 samples of cartridge proportional needle valves. 2 months later, Devante informed that the market promotion of the upgraded equipment was smooth. Their engineers were satisfied with AAK hydraulic cartridge proportional needle valves, especially its variable flow gain characteristics, and smooth flow characteristics, small pressure impact during pressure relief, and accurate flow control. We mainly made 3 ingenious actions on the valve housing and valve spool, and solved the problem that HydraForce didn't want to do. 1. The lower part of the valve spool is arranged in the valve housing and sealed with the valve housing line. The upper part of the valve spool is connected with the control cover plate, the upper end of the control cover plate is connected with the valve cover with threaded holes, and the displacement sensor is installed on the threaded holes of the valve cover. The lower end of the valve spool is connected with the upper cavity of the valve spool. When the valve spool is at the lowest end, the valve is closed. When the valve spool moves upward, the valve gradually opens.
Integrated Hydraulic Threaded Cartridge Valve, AAK replaced 3 HydraForce Valves with 1, which is simplified and cost effective Esteban is from a Spanish hydraulic equipment manufacturing company. Some time ago, their company customized a hydraulic cylinder for a customer. The hydraulic check valve, relief valve and electromagnetic unloading valve in the system are all standard parts from HydraForce. The customer is basically satisfied, but the cylinder structure is not very satisfactory, and the price has no advantage. Their engineer said that only by integrating the functions of hydraulic check valve, relief valve and electromagnetic unloading valve, and replacing them with only one hydraulic screw-in threaded cartridge valve, would the structure be simple and the cost be reduced. Esteban inquired about more than 10 hydraulic threaded cartridge valve manufacturers, but no result for a week. Esteban was worried. After browsing AAK website on Google, Esteban found that AAK had many cases of solving customer problems, and sent an email asking: Can AAK customize the multi-function hydraulic threaded cartridge valve to make the cylinder compact and reduce costs? After communication, it was learned that Esteban needed AAK to customize the hydraulic threaded cartridge valve to replace the functions of the 3 valves in the system. According to the hydraulic schematic diagram provided by Esteban, AAK engineers basically had the idea. Esteban asked for samples after knowing it. After 50 days, AAK sent 10 samples of hydraulic threaded cartridge valves. 1 month later, Esteban informed us by email that the customer was satisfied with the new structure of the oil cylinder, and should promote it first, and let us wait for the batch order. AAK used an integrated multi-function hydraulic threaded cartridge valve to replace the 3 valves of the original system, specifically as follows: 1. The valve housing is provided with a connecting valve hole, a working port of the oil cylinder, and a hydraulic control port, an oil inlet port and an oil return port. A check valve spool is set in the valve hole to control the on-off of the oil inlet and the working port for oil feeding or unloading. In this way, the one-way control function is realized and the check valve of the original structure is replaced. 2. The control check valve spool is separated from the working port, and the hydraulic control valve spool for unloading the oil inlet and the working port is connected. At the same time, the connection between the valve hole and the relief valve spool of the oil return port can also be disconnected. In this way, the overflow function is realized and the relief valve of the original structure is replaced. 3. The relief valve spool is equipped with connecting valve hole, oil return port and damping hole. One end of the damping hole is equipped with a unloading valve spool to control the opening and closing of the damping hole and the oil return port,
Hydraulic Cartridge Pressure Control Valve with 450bar pressure resistance, AAK's service life is twice that of its peers Gallagher is from a hydraulic equipment manufacturing company in Brazil. His purchase has been smooth, but a hydraulic cartridge pressure control valve stumped him. In the second half of last year, they purchased high-pressure hydraulic cartridge pressure control valves for hydraulic power units. About half a year later, a customer complained that the hydraulic cartridge pressure control valve was leaking. According to the feedback from the original hydraulic cartridge pressure control valve manufacturer, the leakage was caused by ultra-high pressure 450bar and it can only be replaced with new one. Gallagher realized that the service life of the hydraulic cartridge pressure control valve produced by the original manufacturer was only 6 months, and the customer required at least 1 year. Gallagher contacted other cartridge valve manufacturers, but none of them was able to guarantee the service life of 1 year for the hydraulic cartridge pressure control valve that is resistant to ultra-high pressure of 450bar. Gallagher was worried. Gallagher found AAK website on B2B, noticed many customer cases related to hydraulic cartridge pressure control valves, and sent an email asking: Can AAK ensure that the hydraulic cartridge pressure control valve withstand ultra-high pressure 450bar working condition, and the service life is more than 1 year? According to the hydraulic system schematic diagram and the original production drawing of the hydraulic cartridge pressure control valve, AAK engineers found that the pressure relief method has a great impact on the valve, will consume the valve life, and is easy to leak. Gallagher asked AAK to make samples. After 35 days, AAK delivered 30 hydraulic cartridge pressure control valves. Last week, Gallagher informed us by email that AAK hydraulic cartridge pressure control valves had been used for 9 months, and no customer complained about leakage. The boss asked to purchase in bulk from AAK to replace the original hydraulic cartridge pressure control valves. I told him that 1 year's life is our basic requirement. He told me that his boss valued the service life of AAK hydraulic cartridge pressure control valve. The other cartridge valve manufacturers can only guarantee a service life about 6 months, while AAK could last more than 1 year. The pressure relief mode of this hydraulic cartridge pressure control valve, is optimized from the following 3 points: 1. The valve body of the hydraulic cartridge pressure control valve is divided into the upper valve body and the lower valve body, and then sealed and fastened with bolts to form the valve body. One end of the valve hole of the upper valve body is used as the pressure fluid inlet, and one end of the valve hole of the lower valve body is used as the pressure fluid outlet.

The leakage of Hydraulic Cartridge Flow Control Valve caused by spring was solved by AAK from 3 points Adam, an old American hydraulic customer, sent AAK 3 emails consecutively on the same day last month, for the leakage of a hydraulic cartridge flow control valve. According to the picture he sent, the hydraulic cartridge flow control valve has a cut-off plate that is supported by a spring. Some customer complained that the hydraulic cartridge flow valve leaked without working. The original manufacturer of the hydraulic cartridge flow control valve cannot solve the problem in 3 months. Because the sales volume of this hydraulic cartridge flow control valve is very good, Adam wants it 100% no complaints. Through the pictures, it is difficult to trace the cause. I suggested Adam send us 3 samples of the original hydraulic cartridge flow control valves. After we received and checked the samples, we found that the leakage was more serious if we pressurized, but the tightness of the cut-off plate was no problem. We adjusted the spring, and the first pressurization did not leak, but after 3 times, the leakage occurred. It was basically judged that the spring has hidden danger. After the spring tension test, it was found that the spring is abnormal. 2 days later, we informed Adam of the hidden danger of the spring, and at the same time, we replaced the internal springs of the 3 hydraulic cartridge flow control valves with AAK springs, and returned the samples to him. 2 weeks later, Adam sent a PO for this hydraulic cartridge flow control valve, with a value of more than 30,000 dollars, and told us that the 3 returned samples were tested for 5 pressurizations, and no leakage was found, and the operating efficiency of the hydraulic system was also improved by nearly 10%. Adam privately ridiculed himself. He has been engaged in the hydraulic valve market for so many years, but still has to ask for help from AAK when there is a problem that he cannot solve. The main reason why AAK can effectively solve the leakage problem caused by springs, is to ensure the following 3 points: 1. We have our own spring source that has cooperated with us for 10 years, to avoid the phenomenon of unequal material between the sample and the production spring, and ensure the quality. 2. Equipped with spring tension and compression tester, reasonably select the spring with elastic coefficient within the standard range, to avoid leakage caused by elastic coefficient deformation. 3. A quality inspection department to ensure that the quality is qualified during assembly and prevent leakage. AAK hydraulic cartridge flow control valve, 3-step check on the spring, zero leakage, welcome to try!

The 2022 annual report of AAK Hydraulic Valves, focusing on moving one step every day The gap between grass roots is not cognition, but the skill of making money. The gap between the elite and the elite is not skills, but the perception of making money. I have always positioned myself as a grass root and have been in the hydraulic valve industry for 14 years. Now I don't need to worry about the production workshop and there is a team for technical innovation. I need to constantly learn network skills and improve the network salesperson of AAK hydraulic valves. Over the past a few years, I have achieved little and I am satisfied. At present, in most online businesses, most salesmen hope to use a detail page to burn advertisements. Anyway, the money is the boss's, not his (her)'s. If there is no customer coming, the responsibility lies in the company, and it has nothing to do with him or her. There are not a few people who have this understanding and attitude, and they have reached a consensus. This is a lazy government in function. Lazy politics is one of the corporate cultures, which is hard to reverse. It seems that online marketing is the responsibility of advertising, and the boss is unlucky. AAK hydraulic valve online business, is to do a lot of things online, will slowly have inquiries. Most of the time, even if you have done a lot of things, you must do the content right, which is what customers want to see and need to see. On the contrary, if the content is wrong, the effort will be wasted. Do it every day. You must do it every day. If you don't do it, you will get 100,000 whyâ??s. Once started, there were only 3-5 questions left. There is only one reason for endless questions â?? you donâ??t do it. AAK hydraulic valve is not directly oriented to the consumer market, but mostly oriented to enterprise customers. For a long time, AAK has been focusing on the production technology and process of hydraulic cartridge valves, benchmarking the global leader in the hydraulic industry. The invisible champion enterprises in Germany often inherit several generations, and do not pursue the road of diversified and rapid expansion, but instead dig deeply into a specific field, achieve "one finger wide, one kilometer deep", and accumulate deep technical reserves and stable market channels. This is the future of AAK hydraulic valves. Today is the last day of 2022. I always feel that I can't say enough. I'm worried that there is no logic. I still use rules to summarize the year of AAK hydraulic valves. This is also an annual report of AAK hydraulic valves to everyone who is following AAK. 1. 326 - 326 tweets have been published annually on the AAK hydraulic valve website. It is conservatively estimated to be more than 260,000 words. 2. 86 - AAK hydraulic valve tweets are published on 86 B2B platforms every day. 3.
Hydraulic Cartridge Directional Control Valve with high-precision valve hole, AAK helped Santiago win big order The cylindricity of the valve hole of the hydraulic cartridge directional control valve is 0.002mm, and the roughness is Ra0.05. The supplier who has cooperated for 3 years gave up 2 weeks after receiving the order. After AAK took over, the precision of the hydraulic cartridge directional control valve was constantly challenged from 3 aspects. After processing, the cylindricity was less than 0.001 mm, the roughness was Ra 0.04, and the consistency of component dimensions was within 0.001 mm. 3 months later, Santiago gave AAK an order for 1000 hydraulic cartridge directional control valves. Santiago is from a hydraulic equipment manufacturing company in Brazil. In January this year, their company needed a batch of hydraulic power units with high requirements, which also had high requirements for hydraulic cartridge directional control valves, especially the valve hole cylindricity below 0.002mm and roughness Ra0.05. Santiago chose a hydraulic cartridge valve manufacturer who had cooperated for 3 years to make samples. 2 weeks later, the manufacturer gave up due to not able to meet the valve hole high accuracy of the hydraulic cartridge directional control valve. Santiago found AAK on Google and needed our help to sample it. After communication, we learned that the original manufacturer was not helpful. I told him that for hydraulic cartridge valves with similar accuracy, we had customized them and also supplied them to Brazilian customers. Santiago seemed to see hope and sent a test order for 20 hydraulic cartridge directional control valves. After 40 days, AAK delivered samples. After receiving the samples, Santiago just advised us that the sample accuracy met the requirements, and there was no further news. 3 months later, Santiago suddenly sent us an order for 1000 hydraulic cartridge directional control valves, and advised us that their customer was very satisfied with their hydraulic power units. They successfully received a large order from customer. They also stressed the importance of large goods, and should ensure that there is no deviation in accuracy. AAK's machining of hydraulic cartridge directional control valve holes with high precision requirements mainly comes from 3 points. Once determined, there is no deviation. 1. In the rough machining process, the high-precision machine tool in Japan and the high-pressure internal cold drilling U-drill are used. The range of valve hole diameter can be 13.5mm, and the hole straightness can be within 0.02mm. General hydraulic cartridge valve manufacturers do not have this kind of drill. 2. In the high-precision valve hole honing, the fixed size honing is adopted, which does not expand or shrink during processing, and the size allowance can be gradually removed in order.
AAK Optimized the Hydraulic Direct Acting Cartridge Relief Valve with 3 tricks, Gaylord gave up the original Indian manufacturer Gaylord comes from Holland and is an old customer of AAK hydraulic valve. Some time ago, he emailed me to ask if AAK could optimize a hydraulic direct acting cartridge relief valve. After communication, I learned that at the beginning of the year, they had an order for a hydraulic power unit for high-precision machine tools, which used a hydraulic direct acting cartridge relief valve. Gaylord chose an Indian hydraulic cartridge valve manufacturer to make samples, and the equipment debugging was not smooth. The hydraulic direct acting cartridge relief valve had unstable overflow liquid, forming a jet, especially under low pressure, the stability of the system was poor. Although the function test of the valve was normal, it was still necessary to optimize the hydraulic direct acting cartridge relief valve, but 2 weeks later, the original manufacturer still had no solution, and Gaylord contacted me. According to his hydraulic system schematic diagram and the drawing of the original hydraulic direct acting cartridge relief valve, AAK engineers found the hidden danger of the original structure. Gaylord sent the PO of the test order. After 50 days, AAK sent 10 samples of hydraulic direct acting cartridge relief valves. A month later, Gaylord sent us an email. The equipment was adjusted smoothly. Under low pressure, the system was stable. The customer was also satisfied with the prototype. His engineers also admired the brains of AAK technical team. AAK hydraulic direct acting cartridge relief valve has good stability under low pressure conditions. The key lies in its unique structure: 1. The valve spool, spring, plunger and pressure regulating knob are successively installed in the cavity of the hydraulic cartridge relief valve body. The valve spool contacts the valve seat under the elastic force of the spring, and relies on the elastic force of the spring and the back pressure of the overflow port to balance the hydraulic pressure generated by the oil inlet. 2. The original poppet valve spool is changed into an integral ball type valve spool, and an annular gasket is set between the ball valve spool and the spring. The ball valve spool can automatically adjust the axial angle relative to the centering bearing, which improves the stability of the valve and ensures the low pressure stability of the hydraulic system. 3. Before assembly, the standard steel ball is used to punch the runner port and gasket port that contact the steel ball. The original wire seal is changed to ring seal to improve the sealing performance, so as to ensure the reliable contact between the gasket and the steel ball and realize the stable overflow function. AAK hydraulic direct acting cartridge relief valve, is also stable in low pressure, you can also try a small order!
Zander is from a hydraulic manufacturing company in Greece. In the first half of this year, their company planned to upgrade the old logistics crane and put it back on the market. Its main goal is to improve its stability by 20% compared with its peers. The optimization of the hydraulic cartridge counterbalance valve is the key, but the original hydraulic cartridge counterbalance valve manufacturer has no ability to innovate. Zander found a local hydraulic cartridge valve manufacturer to optimize the structure and make samples. However, during commissioning, when the load of the system drops, the pressure fluctuation cannot exceed that of the peers, and the hydraulic cartridge counterbalance valve cannot avoid load interference. The local hydraulic cartridge valve manufacturer has no ability for further improvement. 2 months passed by, but there was still no solution. The boss pushed for progress many times, and Zander was worried. Zander found AAK on Google, noticed that AAK had released some customer cases about hydraulic cartridge counterbalance valves, and sent us an email. According to the schematic diagram of the hydraulic system and the original hydraulic cartridge counterbalance valve drawing provided by him, AAK engineer informed that the structure optimized by his local hydraulic cartridge valve manufacturer was not reasonable and needed to be adjusted. AAK has a trick to prevent the hydraulic cartridge counterbalance valve from being affected by the load. Zander asked for AAK samples. After 45 days, AAK sent 20 samples of hydraulic cartridge counterbalance valves. 3 months later, Zander sent an order for 500 hydraulic cartridge counterbalance valves, and told us that their technical department was very satisfied with AAK hydraulic cartridge counterbalance valves. Not only did they overcome the load impact, but also improved the stability of their new logistics crane by more than 20%. In the promotion stage, the booking was good, and the boss was happy. AAK hydraulic cartridge counterbalance valve can stably control the opening of the valve spool without being disturbed by the load, and its stability is higher than that of its peers, because we have tricks on optimizing the structure. AAK hydraulic cartridge counterbalance valve is composed of a valve body, a valve seat, a main valve spool, a pilot valve spool and a pilot mechanism. The valve seat is connected with the valve body and forms a connected first channel. The extended end of the valve seat butts against the pilot mechanism and forms a second channel. The main valve spool is provided with a throttling slot. One end of the pilot valve spool slides and is arranged in the inner cavity of the main valve spool. The other end is connected with the pilot mechanism. The pilot valve spool is equipped with a throttling slot. The pilot valve spool is connected with the inner cavity of the main valve spool as a balanced structure.
With 3 Tricks to Strengthen the Valve Spool, the service life of AAK Hydraulic Cartridge Directional Control Valve is twice that of its peers 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.
AAK 3 Skills Solved the problem of Hydraulic Counterbalance Cartridge Valve Caused by Back Pressure and helped Dorian's Equipment to be Promoted Smoothly Dorian is from a Greek hydraulic equipment company and is responsible for the procurement of hydraulic components. At the beginning of the year, they developed a new hydraulic crane, which requires the use of hydraulic counterbalance cartridge valve. Dorian worked with a local manufacturer to make samples. During the equipment commissioning, it was found that the hydraulic counterbalance cartridge valve had no overflow function due to the back pressure. The hydraulic system was tested separately, but it was normal. Dorian felt that there was a hidden danger in the original design of the hydraulic counterbalance cartridge valve. The engineer thought that the function of the hydraulic counterbalance cartridge valve was not up to standard. Dorian was a little embarrassed. Dorian found website of AAK hydraulic valves on Google, and noticed that AAK had been supplying first-line brand hydraulic valves such as HydraForce, SUN Hydraulics, and HAWE for many years. Maybe he saw hope and sent an email to ask for help. According to what he said, the hydraulic counterbalance cartridge valve has no overflow function under the influence of the back pressure of the closed central circuit. I told him that it was probably a flaw in the design of the original hydraulic counterbalance cartridge valve. According to his hydraulic schematic diagram and original drawing of hydraulic counterbalance cartridge valve, AAK engineer not only determined that the problem was in the original design, but also had a solution. After knowing these, Dorian asked AAK to make samples. After 50 days, AAK sent 10 hydraulic counterbalance cartridge valve samples. 4 weeks after AAK hydraulic counterbalance cartridge valve samples were sent, Dorian told me that the equipment debugging was smooth and the market promotion had been started. I was asked to wait patiently for the batch order. The rapidity and stability of AAK optimized hydraulic counterbalance cartridge valve is the key to smooth equipment commissioning. It solves the contradiction between the rapid response and stability of the equipment in the early stage, and the flow change is moderate, the movement is stable, the safety overflow function is not affected by the back pressure, which can be applied to the closed center and open center hydraulic systems. 1. The middle section of the hydraulic counterbalance cartridge valve spool is provided with an inner concave ring, which is also the valve inlet. The right end of the inner concave ring has a cone, on which there is a two-stage stepped taper ring. The cumulative area of the cone is the same as the area of the cylinder end face at the right end of the counterbalance cartridge valve spool.
For instantaneous unloading flow 10000lpm Hydraulic Cartridge Pressure Control Valve, Vadim only found AAK Vadim is from the Netherlands and has been engaged in procurement in a hydraulic equipment company for 3 years. Some time ago, they encountered a complaint about the hydraulic support they sold. The hydraulic column was bent. This has never happened before. The engineer was surprised. After field analysis, the problem was that the maximum unloading flow of the hydraulic cartridge pressure control valve was too small to realize rapid unloading, which affected the hydraulic column. The original manufacturer of the hydraulic cartridge pressure control valve tried to modify it once, but it was ineffective. Vadim contacted more than 10 cartridge valve manufacturers, but they couldn't make hydraulic cartridge pressure control valves with instantaneous unloading flow of 10000lpm. Vadim was worried. Vadim browsed AAK website on Google and clicked on the customer case and product introduction of hydraulic cartridge pressure control valves for many times, and left us a message: How to increase the maximum unloading flow of the hydraulic cartridge pressure control valve? My reply: there are many ways to improve it, and we need to make specific analysis. According to the video of bending of hydraulic column and the production drawing of hydraulic cartridge pressure control valve sent by him, after several discussions, AAK engineers have implemented the plan with 90% confidence. Vadim saw the hope and asked for AAK samples. After 50 days, AAK sent 20 samples of hydraulic cartridge pressure control valves. Last week, Vadim sent an email to express his thanks. It has been more than half a year since the hydraulic cartridge pressure control valves of AAK was installed. The customer has not reported that the hydraulic column is abnormal. AAK engineers improved the internal structure of the original hydraulic cartridge pressure control valve and ingeniously started from 3 points. Vadim said that their engineers also applauded and wanted to find opportunities to learn from each other. 1. The valve spool of the hydraulic cartridge pressure control valve adopts a two-stage stepped cylinder structure. When the high-pressure liquid of the system acts on the large diameter end and the small diameter end of the valve spool at the same time, the area difference between the two ends of the valve spool can greatly reduce the hydraulic pressure borne by the valve spool, so as to achieve the stability of the large flow unloading process. 2. On the cylinder wall in the middle of the front half valve body, 12 unloading holes are uniformly arranged along the circumference, which not only balance the force along the radial direction, but also make the valve spool flexible. At the same time, during the unloading process, it has the largest flow section to achieve super flow unloading, and its maximum instantaneous unloading flow can reach 10000lpm.
