Cyrano, an experienced buyer of hydraulic cartridge valves from Greece, encountered difficulties with a batch of hydraulic cartridge relief valves. At the beginning of the year, they developed a hydraulic power unit and used a hydraulic cartridge relief valve purchased from a hydraulic cartridge valve manufacturer in Ningbo. During the commissioning of the hydraulic power unit, the operation was not stable. Their engineer found that when the overflow flow rate changes greatly, it is easy to cause a large change in the pressure at the inlet of the hydraulic cartridge relief valve. The original manufacturer reported that this hydraulic direct-acting relief valve is a standard part benchmarking HydraForce, they should have their engineer to control the system's overflow flow fluctuations, which embarrassed Cyrano. Cyrano found AAK on Google and noticed that AAK has had multiple cases of solving difficult and complex problems for customers. He emailed us to ask, "How to improve the stability of HydraForce's standard hydraulic direct-acting relief valve?". This question is too big to answer. After communication, it was learned that he had encountered a problem matching the standard part of the hydraulic cartridge relief valve with his equipment. The direction is clear, but whether to choose to optimize A to match B or optimize B to match A, there are only these 2 options. AAK engineer asked if it is possible to replace the hydraulic direct acting relief valve with a pilot operated relief valve? AAK can design according to the working conditions. He paid the development fee the next day, and 40 days later, AAK sent samples of the hydraulic cartridge relief valve. Last week, Cyrano informed that after AAK hydraulic cartridge relief valve was installed in the system, when the overflow flow changed significantly, the pressure at the inlet of the hydraulic relief valve did not change much. Their engineers were very happy and there would be no need to change the system. AAK hydraulic pilot operated relief valve can replace HydraForce hydraulic direct acting relief valve, which is actually very simple. The pilot valve and the main valve are combined to form a whole. The pilot valve controls and regulates the overflow pressure, and the main valve functions as an overflow valve. The two ends of the main valve plug are subjected to oil pressure. The main valve pressure spring is made of small stiffness material. When the overflow flow rate changes greatly, the compression amount of the pressure spring does not increase, and the pressure at the oil inlet is stable. 1. AAK hydraulic pilot operated relief valve is equipped with a first liquid chamber and a cavity for installing the valve spool. The first liquid chamber and the cavity are connected through a through hole. One end of the valve spool is located in the through hole, and the other end is connected to a pressure regulating device, which is fixed on the valve body. 2. The main valve seat is provided with an oil inlet and a return port, which are connected to the oil return port. The plug plugs the oil inlet and return ports through their ends and sides, respectively. The plug connects to the valve body through a pressure spring, and the plug has a damping hole. 3. The pressure regulating device consists of a pressure regulating screw and a spring. One end of the pressure regulating screw is connected to the spring, and the other end of the pressure regulating screw is connected to the valve body. The end face of the plug plugged into the oil inlet is a conical surface. AAK hydraulic cartridge pilot operated relief valve, high stability, you can also try it! https://www.aakindustry.com/info-detail , /cartridge-relief-valves-aak539

Last week, the video I sent to Frank about how hydraulic cartridge valve manufacturer AAK processes the valve spool of hydraulic cartridge flow control valves using a centerless grinder was not approved by him, which made me very disappointed and also helped me understand the requirements of German customers for automated production. Frank from Germany needs to develop a hydraulic flow control valve, but there is a requirement for the accuracy of the valve spool, which requires centerless grinding equipment for precision machining. Frank learned that hydraulic cartridge valve manufacturer AAK has this equipment, so he asked me to take a video of the work for his reference. The next day, Frank said, "Why does it still need a person to assist in completing it?"? I realized that Frank rejected the hydraulic cartridge valve manufacturer AAK because of this. But I'm not too worried, because the automated production process is a strong point of hydraulic cartridge valve manufacturer AAK. Although there is no chance for the hydraulic flow control valve this time, Frank, a customer who is meticulous, will definitely return to AAK. 3 days later, I said to Frank, ‘thank you for your reminder. The mechanical arm plan for automatic material retrieval and feeding equipped for the centerless grinder is already in place. It is expected that in 3 months, I will provide a video of the fully automatic centerless grinder processing the hydraulic flow control valve spool. At the same time, I will also send you some previously unmanned fully automatic processing processes’. Let's go back to last week's video to Frank that using a centerless grinder to process the spool of a hydraulic flow control valve. This CNC centerless grinder is equipped with an automatic conveyor belt. The operator only needs to place the rough machined valve spool on the conveyor belt, and the valve spool is sequentially fed into the grinding area. After one machining is completed, it is automatically placed in the next one. The grinding wheel adopts diamond grinding wheel, which provides a basis for the stable accuracy of the valve spool due to its hardness and wear resistance. The control system of the centerless grinder is stable, with no faults during long-term processing, and the stability of grinding provides assurance for the accuracy and stability of the valve spool. Thanks to Frank's advice again. In fact, the more requirements customers have for you, the more they hope you will grow until you meet the qualifications of their preferred supplier. I like this type of customers. AAK hydraulic cartridge flow control valve, German customer's suggestion, AAK landing, you can also give it a try!

Patrick and I know each other at the PTC exhibition in Shanghai. He has worked in HAENCHEN hydraulic equipment company in Germany for a long time. The first thing he said when he saw me was that “I was attracted by the slogan "Hydraulic valve manufacturer of the world's top 500 companies" on your AAK booth”. We talked about the hydraulic threaded cartridge valves for more than half an hour, especially introduced the difference of AAK hydraulic threaded cartridge valves on the specific details. He was surprised that the details of AAK had caught up with his local hydraulic valve manufacturers in Germany. Shortly after the exhibition, Patrick emailed us a hydraulic threaded cartridge valve with high parameter requirements. In particular, the durability of the hydraulic threaded cartridge valve should be more than 2 million times. All quality details should be compared with their local suppliers in Germany. The drawings attached to the email indicate the detailed data and working condition requirements. AAK is required to send 12 hydraulic threaded cartridge valve samples within 4 weeks. After analysis and comparison, AAK engineers found that this hydraulic threaded cartridge valve is not only durable for more than 2 million times, but also has high accuracy requirements. In particular, the internal leakage requirement of hydraulic threaded cartridge valve is 2drops / min, which is 60% higher than the international general standard. Although the requirements are high, we are still confident. 4 weeks later, AAK sent 12 hydraulic threaded cartridge valve samples. A month after the hydraulic threaded cartridge valve samples were sent, Patrick emailed that AAK did make him realize that it was different from other hydraulic valve manufacturers. At that time, he emailed to 4 Chinese hydraulic threaded cartridge valve manufacturers and a local manufacturer in Germany. Two of the 4 Chinese hydraulic valve manufacturers gave up directly. Only AAK and another hydraulic thread cartridge valve manufacturer confirmed to make samples. They tested and compared the sample parameters of the three factories. AAK's accuracy and durability are not only much higher than those of its Chinese counterparts, but also benchmarked with their local manufacturer in Germany. Although the quotation of AAK hydraulic threaded cartridge valve is much higher than that of its Chinese counterparts, it still has advantages over the hydraulic threaded cartridge valve purchased locally in Germany. Purchasing from AAK is the best embodiment of cost performance. AAK hydraulic threaded cartridge valve has three absolute advantages and has already surpassed its domestic counterparts.   1.  AAK has a high-precision CNC machining center imported from Switzerland and various independent fixtures upgraded and refitted by itself, which eliminates human errors and ensures the first step of accuracy.   2.  AAK engineer team with more than 10 years of technical experience, independent professional research and development, combined with unique research and development technology, to select the raw materials and components according to the working conditions of customers' actual needs, realizing the personalized customization demand of hydraulic threaded cartridge valves, which can not be achieved by 95% of domestic peers.   3. AAK has been OEM for 3 Fortune 500 companies for 10 years. The quality control process is strict, and it is stricter than the ISO certification system. It never relax their requirements, stick to the details and increase R & D. Ensure that the valve spool and valve sleeve of each hydraulic threaded cartridge valve have low friction, anti-fatigue, long service life and high precision. AAK hydraulic threaded cartridge valve has surpassed its domestic counterparts and benchmarked the local manufacturer in Germany.

Hudson is an old purchaser of LARZEP company in Spain. He cooperates with us on are some non-standard hydraulic sequence valves, and often discuss some difficult and miscellaneous problems of hydraulic sequence valves with us. In the second half of last year, their company developed a machine tool hydraulic system, which uses the hydraulic sequence valves to implement the device of positioning first and then clamping. In order to save development time, Hudson purchased directly from Spanish hydraulic sequence valve manufacturers. According to the hydraulic sequence valve drawings provided by Hudson, the factory delivered 20 hydraulic sequence valve samples in 30 days. After the test run, it was found that the positioning clamping device reacted slowly after the machine tool was started. Check the oil circuit and components of the whole hydraulic system one by one, and there is no abnormality. Their engineers speculated that there was a problem with the hydraulic sequence valves. Hudson contacted the original factory. The manufacturer fed back that the samples of hydraulic sequence valves were completely produced according to the drawings provided by LARZEP company, and the dimensional accuracy met the requirements. Their engineers tested the hydraulic sequence valves separately and there was no abnormality. Hudson's team explored for 2 days and determined that there was a problem with the design of the hydraulic sequence valves. Hudson contacted AAK because the hydraulic sequence valve problems encountered several times before were solved by AAK. According to his fault description, drawings of hydraulic sequence valve, working parameters of hydraulic system of machine tool and video of test run, AAK engineer did find the problem in the design of hydraulic sequence valve. AAK engineer's suggestion is to change the design mode of the hydraulic sequence valve to maintain a minimum "pilot pressure" in the starting circuit and "fully open" when it is higher than the set pressure. This feature can effectively reduce the throttling loss of the system under the working pressure and make the clamping and positioning system of the machine tool sensitive. Hudson team had to stop the machine test and let AAK immediately test the sample according to AAK design recommendations. After 30 days, AAK sent 20 hydraulic sequence valve samples and provided our working schematic diagram. Hudson team installed and commissioned the machine tool after receiving it, and the machine tool was continuously tested for 48H. The reaction of the positioning and clamping device of the machine tool has always been normal. Hudson emailed us that AAK newly designed hydraulic sequence valve was more reliable than their native Spanish ones, and their engineers were surprised by AAK design ability. Thanks to the help of AAK, they succeeded in the test run. Hudson privately told us to wait for the email for the annual order of the hydraulic sequence valves, their team is confident that this machine tool will sell well. His boss is very satisfied with their performance in promoting the new equipment this time. AAK hydraulic sequence valve helps customers make money. You are welcome to give it a try! https://www.aakindustry.com/info-detai , l/hydraulic-sequence-valves-aak185

AAK, as a manufacturer of producing hydraulic valves, has been doing ODM hydraulic valves for 10 years for 3 of the world's top 500 in the industry. In the years of labeling these big brand hydraulic valves, the overall quality of the factory has improved significantly. The operation of each workshop is standardized, the quality control process of hydraulic valves is strict, and the self-implementation is more strict than the ISO certification system, being meticulous in making hydraulic valves. All of these are valuable assets for big brand ODMs.   In cooperation with these big brand hydraulic valves, AAK has formed a strict process flow, because of them, there is the growth of AAK hydraulic valves. The strength of the factory has improved, and it is natural for the market to respond. I still remember that 10 years ago, I participated in the Ningbo hydraulic valve industry seminar. An old engineer said at the meeting: "It is easier for factories to succeed in making more difficult hydraulic valves". This seems to be in line with our traditional experience: No cross, no crown. That sounds right, but it's not true. Because there is also a contrary saying called "follow the trend". If a hydraulic valve manufacturer does the right thing, it is not only easy to succeed, but also not difficult. The experience of AAK hydraulic valves over the years is the same. If some styles of hydraulic valves are easy to do, you do not feel particularly difficult and can get help everywhere, they are more hopefully to be successful. I think that if you put the difficulty and success of the hydraulic valves together, and want to find the causal relationship between them, this idea itself has a problem. If you put the difficulty of hydraulic valves and the growth together, it may be right. The success of making a hydraulic valve with appropriate difficulty is not certain, but it will lead to our growth for sure. If we make this hydraulic valve, it will be helpful to our technological growth, and AAK will do it without hesitation. Ten years ago, China's hydraulic valves were almost supplied to some domestic manufacturers of mechanical equipment, perhaps because of the simple process or the trend of hydraulic valve manufacturers. At that time, AAK hydraulic valves began to be tested by HydraForce. At that time, it was difficult to find a third manufacturer who could understand English hydraulic valve drawings in Ningbo. Five years ago, international equipment manufacturers, industrial manufacturers and hydraulic valve brands began to purchase hydraulic valves from China. AAK hydraulic valve was the first to try tomato. AAK hydraulic valve has been doing ODM hydraulic valves for 3 of the world's top 500 in the industry for 10 years. The quality control process of hydraulic valves is strict, which is more strict than the ISO certification system. It is meticulous in making hydraulic valves. However, AAK hydraulic valve has never relaxed its requirements, stuck to details and increased research and development, because we know that when the growth of hydraulic valve customers exceeds that of AAK, AAK hydraulic valve will be abandoned slowly. Therefore, we must run in front of customers, lead customers, and then help customers make money. AAK hydraulic valve, the choice of international hydraulic valve brands, you are also welcome to have a small try. https://www.aakindustry.com/info-detai , l/hydraulic-valves-aak184

For a hydraulic manifold block with many deep holes and great difficulty in finishing, the original hydraulic manifold block manufacturer worked on the trial order for 15 days. After 15 days of processing, the single hole processing cost increased by nearly 30%, and the production efficiency was only 1/5 of the normal. Leon understood that the processing cost was not affordable and had to change the manufacturer of the hydraulic manifold block. After AAK took over, the welding reamer with special groove and blade design was used to replace the conventional hard reamer. The linear speed was up to 680m/min, the production efficiency was increased by more than 10 times, and the processing cost of single hole position was only 1/3 of that of the original hydraulic manifold block manufacturer Leon, from Germany, is one of our old customers, mainly purchases hydraulic valves. Leon contacted me a few days ago and asked me to try a special hydraulic manifold block test order, and specifically reminded that the original manufacturer used a hard reamer in the finishing process, the roughness can only reach about Ra1.6, the linear speed is not higher than 50m/min, and the tool processing service life is not more than 300 pieces. The aperture tolerance of this hydraulic manifold block shall be ± 0.005mm, and the hole wall roughness shall meet Ra0.8 and Ra3.2 at the same time. If the conventional coating hard reamer is used, the machining accuracy is difficult to reach the standard, and the service life of the tool is very short, which greatly increases the single hole processing cost, that is, increases the customer's purchase cost. After 3 days of research and discussion, we replied Leon that AAK was 90% confident. After 25 days, AAK sent 6 hydraulic manifold block samples. 2 weeks later, Leon told us that the precision of AAK hydraulic manifold block fully conforms to the system error standard, and hoped that we could provide a competitive development price. Leon was surprised that how did AAK hydraulic manifold block achieve that the hole processing cost was 1/3 of the original manufacturer's, and the production efficiency was more than 10 times higher? In view of the structure and processing technology of the hydraulic manifold block, AAK technical team realized that the traditional hard reamer processing technology was not suitable for the processing of this hydraulic manifold block. Through repeated design verification and trial cutting, it is finally determined that the welding reamer with special groove and blade design should be used to replace the conventional hard reamer, with the linear speed of 680m/min, the efficiency increased by more than 10 times, the tool processing service life increased from 300 pieces to 2,500 pieces, and the processing efficiency and tool service life increased significantly. AAK hydraulic manifold block, not only high precision, welcome to try! https://www.aakindustry.com/info-detai , l/hydraulic-manifold-blocks-aak462

Tim comes from Mexico, and started purchasing hydraulic cartridge directional control valves from AAK 3 years ago, including customized ones and models benchmarking SUN or HydraForce. At the beginning of this year, Tim wanted AAK to lower the price of a hydraulic cartridge directional control valve equivalent to HydraForce. The reason was that he received quotations from other hydraulic cartridge manufacturers in China, which were 13% cheaper than AAK. I gave him a 3% discount, but Tim still chose a new hydraulic cartridge valve manufacturer. 3 months later, Tim came back to AAK. After communication, it was learned that he had encountered trouble with burrs in the hydraulic cartridge directional control valves produced by the new hydraulic cartridge valve manufacturer. Within 3 months of delivery from the new hydraulic cartridge valve manufacturer, some customers complained that a small amount of hydraulic cartridge directional control valves were stuck, due to burrs. The manufacturer of the hydraulic cartridge directional control valve blamed that it was caused by the uncleanness of the hydraulic oil. Tim realized that he had chosen a hydraulic cartridge valve manufacturer with unstable quality, there won't be much gain from further discussion. He could only stop losses in a timely manner. Tim knows that it has been 3 years since purchasing the hydraulic cartridge valves from AAK, and there has never been jamming of the hydraulic cartridge directional control valve due to burrs. I laughed and said to Tim, 'You can't always think of AAK only when you fall into troubles with other hydraulic cartridge valve manufacturers in China.’ Tim asked me to deliver 20 hydraulic cartridge directional control valves as soon as possible, resolving the customer's complaints first. After 3 days, the AAK samples were delivered and Tim's troubles were also resolved. How can hydraulic cartridge directional control valves be guaranteed to be free of burrs? AAK prefers abrasive flow deburring. Our technicians operate it this way: First installing each hydraulic cartridge directional control valve into the abrasive flow disc, covering it with a disc cover, and then setting parameters such as injection pressure, injection angle, and injection duration for the abrasive flow equipment. Then start the program and the device will run for 2 minutes before completing the deburring process, while most hydraulic cartridge valve manufacturers in China complete it in 70 seconds to save time. If it is less than this time, it may cause a small amount of burr residue. Finally, the worker used an air gun to blow out any remaining abrasive particles on each components of the hydraulic cartridge directional control valve. Due to the characteristics of semi-solid abrasives, like "mud", they are flowable and have adsorption properties. Under compression, the abrasive shuttles through various channels, taking away hidden burrs that are difficult to clean. The enclosed areas of the components are deburred and also polished. AAK hydraulic cartridge directional control valve, without burrs, and very shiny polished, you can also give it a try!

This week, we’d like to introduce a Hydraulic Cartridge Direct-Acting Relief Valve equivalent to SUN standard part RDFA. The direct-acting relief cartridges are normally closed, pressure-limiting valves used to protect hydraulic components from pressure transients. When the pressure at the inlet (port 1) reaches the valve setting, the valve starts to open to tank (port 2), throttling flow to limit the pressure rise. These valves are smooth and quiet, essentially zero leak, dirt tolerant, immune to silting and are very fast. Last year, one of our Russian customers sent inquiry for model RDFA Direct- Acting Relief Valve, 10 pcs for trial order and 500 pcs for annual order. At that time, AAK did not have existing procedure for this model yet, and it takes at least 30 days for us to develop it. The customer did not have time to wait and purchased the existing stocks from another hydraulic cartridge valve manufacturer in Ningbo China. But they have been purchasing other hydraulic cartridge valves as well as customized hydraulic manifolds from AAK, and are very satisfied with the quality. At the beginning of this year, they checked with us again if AAK can provide RDFA Direct-Acting Relief Valve now, because the valves they purchased from AAK have the longest average service life, they want to buy this model from AAK. We delivered 10 pcs of testing samples on March. Last week, we received the 500 pcs of annual order for RDFA from this Russian customer, which means that AAK samples have passed their testing. AAK hydraulic cartridge direct-acting relief 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-RDFA Hydraulic Direct-Acting Relief Valve: Max.

Discover our Through Conduit Parallel Disc Slab Gate Valve, sourced from a reputable supplier in China. This valve complies with API 600, API 6D, and ASME B16.34 standards, offering reliability and performance. Available in sizes ranging from 2 to 48 inches and with class ratings of 150-1500 LB, it is crafted from carbon and stainless steel. Trust our commitment to quality for your through conduit parallel disc slab gate valve needs. I. Through Conduit Gate Valve Introduction The through conduit gate valve is a sliding valve whose gate is a parallel gate. The shutter can be a single shutter plate or a double shutter plate with a deployment mechanism in between. The push force of the gate to the valve seat is controlled by the pressure of the medium acting on the floating gate or floating valve seat. If the through conduit gate valve is a dual shutter through conduit gate valve, the spreading mechanism seen in the two shutters can compensate for this pressure. 1. The valve seat adopts the floating valve seat structure with o-ring sealing and pre-tightening force, and the inlet and outlet of the flat gate valve are sealed in both directions; in addition, the switching torque of this structure is 1/2 of that of the ordinary valve, and the valve can be easily opened and closed. 2. When the flat gate valve is fully opened, the channel is smooth, the flow resistance coefficient is extremely small, and there is no pressure loss, and the pipeline can be cleaned with a hair ball 3. The filling material structure with self-sealing ability is adopted, which does not need to be adjusted frequently, the switch is extremely light, and the sealing performance is reliable. The auxiliary sealing grease injection structure is set at the filling material, the sealing performance is absolutely reliable, and zero leakage is truly achieved; It solves the disadvantage that the general valve packing is most likely to leak. 4. When the through conduit gate valve is closed, the high pressure in the inner cavity can be automatically eliminated, which is convenient to use. 5. The fully enclosed structure has good protection performance and can meet all- weather requirements. Ⅱ. Applicable Occasions for Through Conduit Gate Valve 1.

Carter comes from an excavator manufacturing company in Italy, and the purchase of hydraulic needle valves has been smooth in recent years. At the beginning of last year, an excavator sold by their company for less than 6 months was complained by customer. The boom of the excavator falls too fast due to its own weight, which is easy to cause danger. Their technician found that there was a problem with the hydraulic needle valve of the hydraulic system. There were obvious wear marks at the contact point between the valve spool and valve seat of the hydraulic needle valve, which was easy to leak. The leakage of the hydraulic needle valve will cause the oil saving and speed limiting circuit of the hydraulic cylinder to be uncontrollable. The boss was very angry that the equipment sold for only half a year was complained and asked Carter to find out the cause of the hydraulic needle valve problem and solve it. Carter contacted the original manufacturer of the hydraulic needle valves and requested to replace the hydraulic needle valves. The manufacturer said that the service life of hydraulic needle valves under 450bar working condition is basically 6 months. The only way to solve this complaint is to replace the hydraulic needle valves every 6 months. Such reply made Carter speechless, because his customer would not accept the high-frequency replacement of hydraulic needle valves, which not only brought a bad user experience, but also the after-sales cost was not cheap. Carter contacted all of his hydraulic needle valve suppliers, and they all replied that they were not sure to achieve a hydraulic needle valve with a service life of 1 year under the working condition of 450bar. When browsing the website, he found AAK and left a message on the website: How long is the service life of hydraulic needle valves with pressure resistance of 450bar? We replied directly for 1 year or more. The next day, he told the problems encountered in purchasing hydraulic needle valves at the beginning of last year in detail. After receiving the drawing of the hydraulic needle valve, we found that the hydraulic needle valve needed by Carter has much higher requirements than the ordinary hydraulic needle valves. We replied that AAK will select specific materials for samples, which can ensure that the hydraulic needle valves can be used for more than 1 year under normal conditions. If possible, he can directly test the samples. One month later, AAK sent 24 hydraulic needle valve samples. A year later, Carter sent an email saying that the excavator with AAK hydraulic needle valves still have not encountered boom problem yet. Among all of his hydraulic needle valve suppliers, only AAK has a service life of more than 1 year. The surface treatment of the valve body of AAK hydraulic needle valves adopts electromagnetic induction heating. Its main advantages are fast heating speed, light oxidation and decarburization of the workpiece surface, and the surface hardening layer can be adjusted according to needs, which is easy to control. The hardened layer has fine martensite structure and high hardness, strength and toughness. After surface quenching, the surface of the workpiece has large compressive internal stress, and the fatigue breaking resistance of the workpiece is high. Using induction heating surface quenching, the number of fatigue cycles under design load is about 10 times higher than that with ordinary quenching and tempering treatment. AAK hydraulic needle valves, special material selection, high pressure resistance and durability, welcome to have a small try! https://www.aakindustry.com/info-detai , l/hydraulic-needle-valves-aak183

Caleb is an old customer of AAK in Mexico and has purchased hydraulic cartridge valves from AAK for 4 years. At the end of last year, he emailed me to discuss 3 issues related to hydraulic pilot operated relief valves. 1. The internal leakage of AAK hydraulic pilot operated relief valve cannot exceed 1 drop/min. 2. Can AAK hydraulic pilot operated relief valve achieve multi-level pressure control? 3. Can AAK hydraulic pilot operated relief valve be customized within 35 days? Looking closely at these 3 questions, I guess he encountered a problem when purchasing a hydraulic pilot operated relief valve. After communication, it was learned that in September, they developed a multifunctional excavator. Due to time constraints, Caleb purchased the hydraulic cartridge valves from a local hydraulic cartridge valve manufacturer in Mexico, but the test run was not successful. Because the internal leakage of the hydraulic pilot operated relief valve is not up to standard, multi-level pressure control also fails, resulting in a weak excavator and unstable operation. After being optimized by the original hydraulic pilot operated relief valve manufacturer, it still failed to meet the standard, so Caleb wanted AAK to try this hydraulic pilot operated relief valve. AAK engineer's opinion: the valve sleeve and adjusting sleeve of the original hydraulic pilot operated relief valve are the same part. The valve spool is installed from the oil inlet end of the valve sleeve, and then blocked by a retaining ring. The valve spool and valve sleeve are sealed by a gap, which is the source of non-compliance. After discussing with their engineers, Caleb asked AAK to sample in this direction. After 35 days, AAK sent 10 samples of hydraulic pilot operated relief valves. 4 weeks after the samples were sent, Caleb informed us that AAK hydraulic pilot operated relief valve was installed in the system, which solved the problem of causing the excavator to become weak, and the multi-level pressure control function was also available. Yesterday, Caleb emailed us an order for 160 hydraulic pilot operated relief valves. He told me, this is the first order from this customer. His boss is very satisfied with AAK hydraulic piloted operated relief valve, which has the performance advantage of internal leakage, as well as multi-level pressure control feature, allowing them to obtain customer order for excavators. AAK hydraulic piloted operated relief valve, with internal leakage of 1 drop/min, and can achieve multi-level pressure control functions. Starting with the sealing method, we divide the valve sleeve and adjusting sleeve of the hydraulic relief valve into 2 parts. The valve sleeve and valve spool are sealed with a cone, as follows: 1. The valve spool of the hydraulic relief valve is located inside the valve sleeve, and the adjusting sleeve and the valve sleeve are fixedly connected in a bayonet type. The spring is inside the valve spool, with one end against the valve seat and the other end against the bottom of the valve spool. 2. The other end of the valve seat is against the pilot valve spool inside the adjusting sleeve, and there is a pressure regulating spring inside the pilot valve spool. The valve sleeve has 2 step through-holes in the axial direction. The junction between the large hole and the small hole is processed into a conical surface, and the valve spool and valve sleeve are sealed at the conical surface. 3. A radial hole for oil control passage is provided between the valve spool and the valve seat. There is a steel ball between the valve seat and the pilot valve spool. There is a circular hole on the valve seat that communicates with the radial hole to accommodate the steel ball, and there is a blind hole on the pilot valve spool to accommodate the steel ball. AAK hydraulic piloted operated relief valve, internal leakage of 1 drop/min, and multi-level pressure control function, you can also try it! https://www.aakindustry.com/info-detail , /relief-valves-aak538
