Valves

When I opened the mailbox this morning, I saw a reorder for 500 pilot hydraulic relief valves from Jimmy. He mentioned that the pilot hydraulic relief valve designed by AAK had been used for 2 years and without any complaints. Jimmy is a purchaser of American company Vickers, responsible for the purchasing of hydraulic parts. 2 years ago, his company encountered a complaint from customer for a hydraulic pump. The customer complained that it screamed after being used for a period of time. After dissecting, their engineer found that there was a problem with the hydraulic relief valve in the hydraulic pump. The boss asked Jimmy to solve the problem as soon as possible. Jimmy sent the hydraulic relief valve back to the original supplier, but the supplier replied that the inspection result was good. Maybe the problem happened during installation. Jimmy’s engineers tested the samples by themselves and found that there was no problem with the hydraulic relief valve, but there was also no problem with the installation method and operation. Now Jimmy is depressed. The boss is pushing for status, but he has no clue. He contacted with several local hydraulic valve manufacturers in the United States, and they all replied that there was no problem on the hydraulic relief valve. One day, after browsing AAK website (www.aakindustry.com) in Google, Jimmy sent an email asking if AAK could help analyze the reason. We replied that it would be better for engineers to have video communication on site Jimmy decided to ask Vickers engineers to make a video with AAK engineers the next morning. After more than half an hour of observation, AAK engineers found that once the pressure oil at the inlet, outlet and control port of the hydraulic relief valve fluctuated, it would produce a scream. We got their original samples and drawings, as well as the working parameters of the hydraulic pump. After 15 days, AAK sent a sample of the pilot hydraulic relief valve. A week later, Jimmy e-mailed us that AAK hydraulic relief valve was installed and tested on site for 24 hours, and there was no scream. Jimmy wondered why there was no scream when AAK hydraulic relief valve was used. AAK engineers analyze the cause from the hydraulic impact. After the hydraulic pressure impacts the main valve spool in the hydraulic relief valve, the pressure oil converges through the check valve, resulting in fluid impact and fluctuation, causing the hydraulic relief valve to oscillate, resulting in the instability of the pressure oil at the outlet of the hydraulic pump. Because the pressure oil output by the pump itself has pulsation, the pressure oil output by the pump will fluctuate strongly and arouse the vibration of the hydraulic relief valve. For the natural frequencies of the two hydraulic relief valves are the same, it causes the resonance of the relief valve and the scream occurs. AAK engineers changed the design to replace the two hydraulic relief valves with the same pilot hydraulic relief valves, and set the corresponding overflow value according to the working conditions. The sample was made based on this process idea. After solving the problem that bothered Jimmy for half a year, he can finally confidently report to his boss. After listening, his boss also praised AAK hydraulic valves and hoped that AAK can produce 50 pilot hydraulic relief valves as soon as possible to solve the complaints from users first. With AAK unique designed pilot hydraulic relief valve, there has been no complaint about scream for two years. Jimmy doesn't want to find a second supplier anymore. AAK pilot hydraulic relief valve, the unique design of the remedy to the case, welcome to have a small try! https://www.aakindustry.com/info-detai , l/hydraulic-relief-valves-aak129

Most hydraulic manifold manufacturers in China do not produce hydraulic cartridge valves, and some even purchase manifold blocks externally. Recently, a listed company in China (with multiple types of hydraulic equipment) left a message on the website of hydraulic manifold manufacturer AAK: Can you produce 300 hydraulic manifolds within 30 days? I didn't reply as soon as I saw it was from the domestic market. The next day, the other party called directly. I replied to him: Sorry, AAK only focuses on foreign markets, and hung up the phone. Surprisingly, on the third day, the other party came to AAK factory directly. After communication, it was learned that a hydraulic manifold manufacturer in Ningbo recommended AAK to him. It turned out that the hydraulic manifold blocks he purchased from the original hydraulic manifold manufacturer had hidden problems, and more than half of them needed to be re produced. This batch of equipment was for Russian market, and ship date could not be delayed. He also knows that the hydraulic manifold manufacturer AAK is focused on the foreign market, and their equipment is also exported to the foreign market. He hopes that AAK can produce this order. Producing 300 hydraulic manifold blocks in 30 days, in addition to redraw work drawings, according to the conventional production layout, time will definitely not be enough. Moreover, the processing difficulty of this manifold is high, and the oil circuit is complex. There should be less than 3 hydraulic manifold manufacturers in Ningbo China that can handle this order. After 2 hours of communication, the other party said that within 30 days, the hydraulic manifold manufacturer AAK can produce as much as possible. Actually, it's not because AAK is conservative or not, but because AAK's vision is in the international market. Our efficient equipment serves our old customers in the international market. It's not too difficult to produce 300 hydraulic manifold blocks with over 20 days of full load production, as long as there is equipment that can process multiple hydraulic manifold blocks at the same time. Most hydraulic manifold manufacturers process manifold blocks one by one. But hydraulic manifold manufacturer AAK has a CNC from Taiwan that can process 8 manifold blocks simultaneously. Simply put, one equipment of AAK is equivalent to 8 equipment of other hydraulic manifold manufacturers. This video has been briefly filmed before, but the fixture of this equipment has flaws, and AAK is currently undergoing personalized customization and upgrading. The advantages of this CNC are high accuracy, a movement speed of up to 48 meters per minute, and equipped with 24 water jet drills. While cooling the cutting tools, it can also wash away chips and avoid residues. The ability to process 8 manifold blocks at the same time is the main reason why we bought this equipment. With one program debugging, we can complete the same surface processing of 8 hydraulic manifold blocks. Eight hydraulic manifold blocks are placed in the fixture and manually tightened, which poses a potential problem and requires experienced technicians to operate. Most operators are still unable to handle this manual process. Hydraulic manifold manufacturer AAK in Ningbo China, has a high production capacity of 1 day equals to 8 days of peers in the industry.

PN16 is a pressure rating that indicates the valve is designed to withstand a maximum pressure of 16 bar (232 psi) at a temperature range of -10°C to +80°C. A gate valve is a type of valve that controls the flow of fluid through a pipeline by using a gate or wedge mechanism to either block or allow the flow. Resilient-seated gate valves have a rubber or elastomer seat that provides a tight seal against the gate when the valve is closed, preventing any leakage through the valve. In the context of BS5163, a gate valve rated PN16 would have a flanged end connection and be suitable for use in waterworks applications with a maximum operating pressure of 16 bar. The valve body and gate would typically be made of cast iron or ductile iron, with a resilient seat made of EPDM rubber or a similar material. Gate valves are commonly used in water supply and distribution systems, wastewater treatment plants, and other industrial applications where a reliable and maintenance-free valve is required. The bs5163 gate valve pn16 manufacturer standard ensures to this specification meet certain quality and performance requirements, and are suitable for use in waterworks applications.

Martin, a purchaser of American company PowerTeam, sent an email last week saying that he saw on the Internet that AAK was a hydraulic valve supplier of some European hydraulic pump companies. He wanted to know whether the quality of AAK could match the quality of the hydraulic valve produced in the United States he was currently using. I directly answered that the quality of hydraulic valves in the United States should also be in different levels, you can have a small try and compare them with your hydraulic valves purchased in the United States. Martin frankly told about his current purchasing status. He needed to re- purchase a batch of hydraulic sequence valves for hydraulic pumps. After placing an order with the original manufacturer in the United States, the manufacturer told him that there were not enough labor for mass production at this moment. He had to wait for 3 months at least. The boss was not satisfied with his purchasing arrangement and asked him to find a new supplier of hydraulic sequence valve and complete production within 2 months. Martin is a little embarrassed because this hydraulic sequence valve has particularly high requirements for various accuracy. In the early stage of development 3 years ago, he contacted more than 20 hydraulic valve manufacturers, compared and tested the hydraulic sequence valves from them, and only the samples from the local hydraulic valve manufacturer in the United States met the requirements. Martin saw the information of AAK to found that it was actually the supplier of hydraulic pumps in Europe. After browsing AAK website (www.aakindustry.com), he felt that AAK hydraulic valve might become his supplier. According to the drawings and working conditions of his hydraulic sequence valve, we found that it does have high requirements for the accuracy of the hydraulic sequence valve. I told Martin that we need 15 days to make and test samples. After the samples of the hydraulic sequence valve pass the test, we will discuss the order at that time. 10 days after the hydraulic sequence valve sample was sent, Martin emailed AAK that the hydraulic sequence valve fully met the production requirements of the existing hydraulic pump. At the same time, the engineers of PowerTeam also applauded every detail of AAK hydraulic sequence valve sample, which was no worse than that of the American company. In particular, some core parameters, such as the matching surface roughness of AAK hydraulic sequence valve spool and valve hole, can reach Ra value of 0.1 ~ 0.2μm. The surface roughness Ra value of the outer circle of the valve spool is 0.1μm. The Ra value of the inner circular surface of the valve hole is 0.2μm. Some parameters are even higher than those of his original American manufacturer, including 100% burr removal. Martin was surprised how AAK hydraulic sequence valve achieve these? AAK hydraulic valve has two absolute advantages and has already surpassed its domestic counterparts. It is uncertain whether it has surpassed its American counterparts. 1. AAK has a high-precision CNC machining center imported from Switzerland and independent fixtures upgraded and refitted by itself, eliminating human errors. 2.The independent professional R & D team cooperates with the unique R & D technology to realize the personalized customization demand of hydraulic valve accuracy, which can not be achieved by 95% of domestic peers. When Martin got the quotation of AAK hydraulic sequence valve, it was 23% cheaper than that produced locally in the United States, but the quality was no worse than that produced locally. AAK needed a lead time of 35 days for production, and the whole time was also in line with Martin's re-purchasing time schedule. After finalizing the whole order, Martin reported to the boss. The boss was very happy that AAK hydraulic sequence valve benchmarked the American quality, and also saved the purchasing cost. Martin told me that his boss asked him to send samples of previously purchased hydraulic valves to AAK for quotation. AAK hydraulic sequence valve keeps pace with American manufacturers. Not only the hydraulic sequence valve, our quality of hydraulic flow control valve also convinced a Germany customer.

Nantan, from Greece, is an old friend of mine. He has cooperated with AAK Hydraulic Valve for 5 years. Last month, I received a sample of hydraulic cartridge relief valve from him. He needed me to optimize it. In the first half of this year, their customer's die casting machine prototype needed to customize the hydraulic cartridge relief valve. Due to tight time frame, Nantan made samples from a local hydraulic cartridge valve manufacturer who had cooperated with them. The equipment commissioning was not smooth, and there was vibration and noise when the hydraulic cartridge relief valve was opened under the condition of large flow and pressure relief. The manufacturer advised that the problem was caused by the internal structure of the hydraulic cartridge relief valve, but he was unable to optimize it. Their engineers complained that the hydraulic cartridge relief valve purchased by Nantan was abnormal, which embarrassed Nantan. Nantan contacted other local hydraulic cartridge valve manufacturers, but they disagreed. Nantan realized that he could only ask for help overseas, so he sent me 3 original samples. According to their hydraulic system schematic diagram, on-site debugging video, AAK engineers suggested that not only the structure of the hydraulic cartridge relief valve should be optimized, but also its functions should be improved. After obtaining additional time, Nantan asked AAK to make samples for the hydraulic cartridge relief valve as soon as possible. After 35 days, AAK sent 10 hydraulic cartridge relief valve samples. A month later, Nantan informed AAK that the prototype had been successfully debugged and delivered to the customer. AAK optimized the structure of this hydraulic cartridge relief valve from 3 aspects, and perfected the hydraulic cartridge relief valve with pressure relief buffer function: 1. The side of the hydraulic cartridge relief valve cage is provided with a valve oil inlet and a valve oil outlet. The valve spool is installed in the axial hole of the valve cage, the control cover plate is at the upper end of the valve cover, and the poppet valve spool and regulating rod are set in the axial hole of the screw sleeve. 2. The upper end of the control cover plate is connected with the buffer valve body. The buffer valve spool is set in the axial hole of the buffer valve body. The control port is connected with the damping hole. The control port is connected with the control chamber through the hole in the middle of the buffer valve spool. 3. The axial hole of the electromagnetic valve body is provided with an electromagnetic valve spool, the working port is connected with the control port through the annular groove in the middle of the buffer valve body, and the oil drain port is connected with the oil return port through the buffer valve body and the control cover plate. The hydraulic cartridge relief valve with optimized structure has high control degree and reliability, small flow resistance, small impact, large flow capacity and fast action when the valve spool is opened in buffer mode, which can effectively reduce system vibration and noise, operate stably and have a long service life. AAK hydraulic cartridge relief valve, small impact, no vibration, you can also have a small try! https://www.aakindustry.com/info-detai , l/relief-valves-aak448

The customers who believe in you will pursue you to purchase your integrated hydraulic cartridge valves; while those who don't believe in you, even after consulting N+1 times, they won't come to you to buy an integrated hydraulic cartridge valve. I have also been requesting our sales department for integrated hydraulic cartridge valves, no value, no quotation; Without trust, it is difficult to make a deal.   At the end of work yesterday, a customer of integrated hydraulic cartridge valve in Turkey, a girl with a beautiful voice really moved me. She told me that she was a Chinese, her parents opened shops in Turkey and operated integrated hydraulic cartridge valves business. Now she is responsible for purchasing all the integrated hydraulic cartridge valves, and is the second generation of the enterprise. A few days ago, she left us a message on B2B, but did not receive a response from us. Then she searched for AAK integrated hydraulic cartridge valve on Google, and called AAK integrated hydraulic cartridge valves in China. I have to sigh that if an integrated hydraulic cartridge valve customer wants to get into contact with you, she will do her best to contact you. It's not a pity if a customer can not get into touch with AAK, either there's no fate or it's not AAK's target customer.   After 20 minutes of telephone communication, I learned that their hometown is Wenzhou and have operated integrated hydraulic cartridge valves in Turkey for many years. In there, users are still accustomed to purchasing and repairing the integrated hydraulic cartridge valves from physical stores, and they have a significant advantage in the local market. I also asked if they have their own warehouse, any agents, and the payment terms for the goods.   She is a very friendly Chinese, our 20 minute conversation was also very pleasant. Unlike some integrated hydraulic cartridge valve customers who were eager to ask for prices at the beginning, they didn't even thank you for the price. This way, they only asked for the price, without comparing the quality of the integrated hydraulic cartridge valves, and over 90% of them would not place an order in the end.   After hanging up the phone, I immediately emailed her and sent her a list of integrated hydraulic cartridge valve models that AAK has, as well as uploaded the e-catalog of AAK integrated hydraulic cartridge valves. Although we haven't met yet, I can feel that she is a very polite person and a detail oriented person. Therefore, I must communicate with her with Co frequency resonance. Spending time with such clients is worth it.   For customers of integrated hydraulic cartridge valves with physical stores, they usually need the service of small batches, multiple varieties, and fast cycle operations. AAK has served 11 physical store customers engaged in integrated hydraulic cartridge valve maintenance and after-sales service, not only does it involve standard parts, but there are also personalized integrated hydraulic cartridge valves, and even very niche integrated hydraulic cartridge valves. The China integrated hydraulic cartridge valve manufacturers that are able to do both design and manufacturing at the same time is less than 10% in Ningbo.   For the integrated hydraulic cartridge valves that other valve manufacturers in China cannot do well, try with AAK. Give me a try and return you a surprise.   AAK HYDRAULIC VALVES (611) 2023-06-23 https://www.aakindustry.com/info , -detail/cartridge-valve-manufacturers-aak611

On Monday afternoon, I received an email from Tony. Tony is a purchasing manager of CASAPPA in Italian, mainly responsible for the purchasing of hydraulic pump components, and the work has been very smooth. Last month, they received a complaint from the largest customer that the pressure at the outlet of the hydraulic pump sometimes rises by itself, resulting in unstable operation of the equipment. The customer's site engineer couldn't solve it and turned to CASAPPA for after-sales service. Although the warranty period has expired, they still need to help customer solve the problem. Their engineers tested various parameters of the hydraulic pump. After comprehensive analysis, they were still uncertain about the root cause, but they suspected that the hydraulic pressure relief valve in the pump is faulty. The engineer asked Tony to contact the original supplier of the hydraulic pressure relief valve and ask him to send a sample of the hydraulic pressure relief valve for replacement and test. It is a local hydraulic valve manufacturer and they still have samples in stock. After receiving samples and commissioning, the engineer's suspicion was proved to be correct. After replacing the hydraulic pressure relief valve, the hydraulic pump worked normally. Tony asked the original hydraulic valve manufacturer to urgently replenish 30 hydraulic pressure relief valves to solve this complaint. The manufacturer said that the shipment has passed the two-year warranty period. At present, there are only 3 samples in stock. The remaining quantity needs to wait in production schedule for production, and can only be delivered after 3 months. If offering this plan to the big customer, Tony would be scolded by the boss. He thought of AAK, because the hydraulic valve failed last year, which was also solved by AAK. Tony established a business relationship with us last October. Now we are also friends besides business. We often discuss the knowledge related to hydraulic valves. His email on Monday is just to ask for help on this hydraulic pressure relief valve. After knowing these conditions, I asked him to send us samples of those faulty hydraulic pressure relief valves, and provide us the drawings of this hydraulic pressure relief valve, noting those special requirements. After receiving and disassembling the samples from Tony, we found that the main valve spool of the hydraulic pressure relief valve was too loose and had increased leakage, then the pressure at the oil outlet increased. The problem should be caused by high-frequency wear or insufficient accuracy of the original shipped hydraulic pressure relief valve. The engineer of CASAPPA asked us to reply why it was determined that it was the problem of the valve spool? Because in the pressure reducing control circuit, after the directional valve works, the flow at the valve outlet becomes zero, but the pressure still maintains the originally set pressure. In this case, the flow through the pressure reducing port is only pilot flow. Due to the small pilot flow, which is generally within 2L / min, the pressure reducing port of the hydraulic pressure relief valve is basically close to the fully closed position and the opening is very small. According to the flow continuity theorem, this part of leakage must also flow from the damping hole of the main valve spool, that is, the flow through the damping hole is composed of pilot flow and leakage. The area of the damping hole and the oil pressure in the spring chamber of the main valve remain unchanged (the oil pressure in the spring chamber is determined by the pre compression shrinkage of the pressure regulating spring that has been adjusted). In order to increase the flow through the damping hole, the oil pressure in the lower chamber of the main valve will inevitably increase. Finally, it is determined that the main valve spool of the hydraulic pressure relief valve is too loose or the accuracy is not enough. The engineer was convinced by our whole demonstration and suggested Tony to take AAK as their main hydraulic valve supplier. AAK produced 30 hydraulic pressure relief valves in 15 days and guaranteed the quality for 3 years. Half a month later, Tony sent an email saying that everything was normal with the hydraulic pump after using AAK hydraulic pressure relief valve. The customer fed back his appreciation to his boss, who was particularly satisfied with his ability to deal with the crisis decisively and paid more and more attention to him. AAK has been doing what peers are unwilling to do. If you have any problem about hydraulic pressure relief valve, or about hydraulic pressure control valve, you can also contact us to have a small try. https://www.aakindustry.com/info-detai , l/hydraulic-relief-valve-aak125

AAK uses endoscope C50 to detect the internal burr of the hydraulic valve block, and then sprays the burr remaining in the hydraulic valve block with high-pressure solution, so that there is nowhere for the burr to hide. Nearly 95% of domestic hydraulic valve manufacturers are not equipped with endoscope and ignore 100% removal of the residual burr of the hydraulic valve block. The American customer who has suffered a loss elsewhere chose to order from AAK again. Most domestic hydraulic valve manufacturers use conventional physical methods to deal with the burr of hydraulic valve block, and check whether the burr is cleaned by experience, especially the burr of deep hole or magnetic burr, which can hardly be cleaned. It is common that the defective rate of hydraulic valve block exceeds the standard due to human error. At the beginning of last year, we received an inquiry for hydraulic valve block from Hunter, an American customer. We calculated the price according to his hydraulic valve block drawings. Hunter was not satisfied with our quotation. Because the communication was very pleasant, I wanted to make friends with hunter and gave up my commission to adjust the price. Hunter frankly said that although the new price of AAK hydraulic valve block meets his target price, the prices of other hydraulic valve manufacturers are still cheaper than those of AAK. We can only withdraw from the purchase of hydraulic valve block amicably. If something goes unusual, there will be problems. 2 months later, Hunter came back to us and said that he was very willing to accept our quotation for hydraulic valve block. He informed that there were different degrees of burrs at the internal cross holes of the hydraulic valve block samples proofed by the original hydraulic valve manufacturer. The hydraulic valve block samples were modified 3 times. Each time the cartridge valve was installed and debugged, the valve spool was stuck from time to time. The factory has also conducted commissioning for many times, and has been unable to remove burrs for 100%. He can only give up this hydraulic valve manufacturer and came back to AAK. Burr must be produced in the drilling process of hydraulic valve block, which is very harmful to the hydraulic system. In addition to adopting appropriate treatment process for burr removal, it is also necessary to have relevant auxiliary testing equipment to guarantee the complete 100% removal of burr. Hunter asked us to arrange approval samples of hydraulic valve block immediately. After 15 days, we sent the hydraulic valve block samples. On the 3rd day after Hunter received the samples, he sent an email to inform AAK that the samples passed testing at one time. Hunter admired that AAK can get the hydraulic valve block samples approved at one time that the peer can't get approval at 3 times. At the same time, he also expressed his curiosity about how AAK can accurately remove the burrs? Because this hydraulic valve block has many internal cross holes and deep holes. Firstly, the accurate position of burr in the hole must be found, and then the burr shall be removed by high-pressure solution jet. Then, AAK has one more process than peers, using endoscope C50 to recheck the subsequent residual burr. If there is still residual burr, it shall be cleaned and rechecked again until it is completely eliminated. This is the detail awareness lacked by other hydraulic valve manufacturers, and also the reason that AAK can achieve 100% deburring. Details make a difference. AAK concentrates on details, strives for perfection. You can purchase at ease, use at ease for all types of hydraulic valves produced by AAK. https://www.aakindustry.com/info-detail/hy , draulic-valve-block-aak124

The day before yesterday, someone left a message on the website of hydraulic cartridge valve manufacturer AAK: I have read several AAK articles about valve cage precision machining, and I would like to know how hydraulic cartridge valve manufacturer AAK ensures the machining accuracy of valve spools? From the IP, it should be a competitor of hydraulic cartridge valve manufacturers. My peers would like to see AAK's processing and equipment, even if they imitate the hydraulic cartridge valve manufacturer AAK, but in fact, I do not reject it. Whether it is a cone type valve spool or a ball type valve spool, machining accuracy is the key. I remember in March this year, Basim from Türkiye met the problem of high-precision valve spool with a peer of hydraulic cartridge valve manufacturers in Ningbo. For 3 samples, the cylindricity of the valve spool hovered between 0.3 and 0.6 µm, and the accuracy was also between 2 and 3 µm. Under the recommendation of a hydraulic cartridge valve manufacturer in Ningbo, Basim contacted AAK. I told Basim that for the cylindricity of valve spool below 0.3 µm and the accuracy controlled within 2 µm, although this requirement is a bit difficult, it can still be achieved in the precision machining process as long as a CNC cylindrical grinder is used and there is precise automatic detection. Basim seemed a bit hesitant, so I went to the workshop and filmed a video of the equipment used by hydraulic cartridge valve manufacturer AAK and how to process the valve spool. After 3 days, Basim requested us to make 12 samples first. For valve spools with high requirements, the first choice of hydraulic cartridge valve manufacturer AAK is Mitsubishi's CNC cylindrical grinder from Japan for precision machining. At the same time, AAK has also upgraded the end face measuring instrument and the outer circle measuring instrument, which can provide synchronous feedback with precision machining. The laser beam from the end face measuring instrument is synchronously irradiated on the valve spool end face, and the generated light wave is received and transmitted to the system. In this way, the precision of the valve spool end face can be dynamically tested. The outer circle measuring instrument measures the surface of cylindrical workpieces point by point and corrects cylindricity from time to time. Once an abnormality is detected, the device will automatically correct the deviation. There may be many hydraulic valve manufacturers who dare to buy Japanese CNC cylindrical grinding machines, but there may not be many hydraulic cartridge valve manufacturers in Ningbo China who dare to upgrade their measurement systems. The higher the precision of the valve spool, the more important it is to focus on precision machining equipment, automated testing system, and specialized machine operation management. With these 3 basic points, after 3 to 6 months of mutual adjustment, human errors are basically eliminated. 2 weeks after Basim received 12 hydraulic cartridge valves samples from AAK, we were advised that their engineers first disassembled 6 samples and approved AAK samples only after testing the accuracy of the valve spool. Hydraulic cartridge valve manufacturer AAK in Ningbo China, focuses on 3 points, and is not afraid of the difficulty of the valve spool. You can also give it a try. AAK HYDRAULIC CARTRIDGE VALVES (720) 2023-11-21 https://www.aakindustry.com/info , -detail/hydraulic-cartridge-valve- manufacturer , s-aak720

Mablevi is from South Africa, and has purchased hydraulic cartridge valves from AAK for 2 years. They are all standard parts of SUN or HyraForce models. The order frequency is high, but the quantity is small. Sometimes 10 pieces are purchased for one style, and sometimes 1 piece is purchased, but AAK has never disliked them. Last week, I received the annual order of 1,000 hydraulic cartridge counterbalance valves from Mablevi, which was unexpected and surprising. At the beginning of last year, their dealers reported that the energy consumption of the excavators they supplied was high. In order to increase the market share, the energy consumption must be reduced. Their engineers optimized the whole hydraulic system and put forward new requirements for the hydraulic cartridge counterbalance valve with energy recovery function. According to the feedback of the original cartridge valve manufacturer, this is the model same as SUN hydraulic cartridge counterbalance valve, which does not have energy recovery function. Mablevi checked with SUN and got the reply that this function is not available, but it can be customized. It requires a high MOQ and high development cost. Mablevi was in trouble. Mablevi thought of AAK and asked: Can AAK customize the hydraulic cartridge counterbalance valve with "energy recovery" function? It is the first time that I received such functional requirement from customer. After communication, I learned that they encountered difficulties in purchasing this hydraulic cartridge counterbalance valve. According to their equipment hydraulic system principle, in the process of load reduction and braking, the mechanical energy of the load is fully converted into internal energy through the throttling of the hydraulic cartridge counterbalance valve to achieve the smooth load reduction and braking, which leads to energy waste. Can we make use of this energy? This is our thinking direction. After 45 days, AAK sent 48 samples of hydraulic cartridge counterbalance valves. 3 weeks after the samples of the hydraulic cartridge counterbalance valve were sent, Mablevi informed me by email that the excavator could work after be installed with AAK hydraulic cartridge counterbalance valve. Their internal test showed that the energy consumption fell by about 20%. It needs to wait the specific feedback from the market. He asked me to wait patiently for the annual order of this hydraulic cartridge counterbalance valve. AAK hydraulic cartridge counterbalance valve can realize the stable load, and the mechanical energy of the load can be converted into pressure oil through the oil recovery hole to realize the energy recovery function when lowering or braking. The key lies in 3 unique structures: 1. The throttling chamber of AAK hydraulic cartridge counterbalance valve is divided into pressure oil chamber, return oil chamber, two oil drain chambers and control oil chamber. The control oil chamber is connected with the control oil port through the throttle, the pressure oil chamber is connected with the pressure oil port, and the two oil drain chambers are connected with the oil drain port. 2. AAK hydraulic cartridge counterbalance valve is also equipped with a three- way pressure compensation chamber with 4 holes (oil inlet hole, recovery oil hole, working oil hole, and control oil hole). The oil inlet hole is connected with the oil return cavity, the oil inlet hole is connected with the oil drain cavity, the control oil hole is connected with the pressure cavity, the recovery oil hole, and the working oil hole is connected with their oil ports. 3. The compensation valve spool and balance spring are installed in the compensation valve chamber. When the compensation valve spool acts, open the recovery oil hole first, and then open the working oil hole. The pressure of the oil inlet hole and the balance spring control the opening of the oil receiving hole and the working oil hole, control the pressure of the oil hole, and control the closing of the oil receiving hole and the working oil hole.

One morning in the first half of this year, shortly after Sam arrived at the company, the boss asked him to come to his office. He realized whether there was a complaint about the hydraulic valve. He saw that the technical director was also in the boss's office. It turned out that the hydraulic check valve installed on the hydraulic pump had leakage in different proportions. These hydraulic pumps were due to ship in 20 days. The boss asked him to purchase the qualified hydraulic check valve in 40 days, because their customer only gave the company a 4-week extension. The technical director informed that according to the on-site detection, about 20% of the hydraulic check valves had leakage. After dissection, it was found that the gap between the valve body hole and the valve spool of these leaking hydraulic check valves was uneven, and some even exceeded 40μm. The gap dimensions are quite different. Sam immediately contacted the original hydraulic valve manufacturer and asked him to replenish 30% to replace those unqualified hydraulic check valves, but he was rejected. Per the original hydraulic valve manufacturer, these hydraulic check valves passed the inspection before delivery and the leaked hydraulic check valves were caused by their improper installation. In the end, the manufacturer didn't even reply to his email. Sam was angry and had to find a new supplier of hydraulic check valve. Sam found AAK HYDRAULIC VALVE in Google and browsed AAK website (www.aakindustry.com), which made him see the dawn and feel that AAK hydraulic valve is different. He emailed us inquiry about the hydraulic check valve and truthfully informed us of the problems he encountered with the Chinese hydraulic valve manufacturer. After several rounds of e-mail communication and integrating the drawings and operating conditions provided by Sam, AAK promised him to offer qualified hydraulic check valve samples within 14 days. If the samples are qualified, the 30% of quantity that he needs can be delivered in 4 weeks. After 14 days, Sam received the hydraulic check valve samples. There was no leakage after installation and commissioning, and the gap between the valve body hole and the valve spool of each hydraulic check valve could be stable within a range and uniform in size. The technical department told him that the standard deviation (sigma) accuracy of the clearance dimension of AAK hydraulic check valve was more than 3 times higher than that of the original supplier. Sam was surprised how AAK hydraulic valve was different? The whole line of production equipment of AAK hydraulic valve is a high- precision machine tool and processing center imported from Switzerland. The core materials are imported from Germany and South Korea, ensuring the production accuracy of valve body and valve spool. The valve spool diameter of this hydraulic check valve is greater than 20mm, and the gap between the valve body and the valve spool needs to be 15μm-25μm, which is an industry requirement, but AAK uses 15μm-20μm as the hard index for production, which is 25% higher than the industry standard. Before each batch of production, the accuracy of each axis of the machine tool needs to be tested, including positioning accuracy, repeated positioning accuracy and reverse positioning accuracy. After obtaining the test data, the accuracy can be compensated. Most hydraulic valve manufacturers ignore this link. That is why the gap dimension standard deviation (sigma) accuracy of AAK is more than twice that of Sam's old hydraulic valve supplier. AAK completed 30% quantity of hydraulic check valves on schedule. Sam solved the unsuccessful procurement without danger. The boss praised him for completing the procurement on schedule and suggested him to find more hydraulic valve suppliers like AAK. AAK hydraulic check valve has guaranteed quality and after-sales service. Our quality benchmarked with international first-line brands.

Timothy is from a Greek hydraulic equipment company, and has been in the company for 5 years. At the beginning of this year, they launched a new hydraulic injection molding machine, focusing on energy-saving and consumption reduction. The hydraulic manifold for the machine is designed internally by them, and they chose a hydraulic manifold manufacturer who has cooperated for 3 years to try samples. Although the equipment debugging is smooth, the energy consumption has not been significantly improved. Timothy guessed that the hydraulic manifold was not efficient, but he had no idea about optimization. The hydraulic manifold manufacturer has solution neither. Timothy also tried to contact more than 10 hydraulic manifold manufacturers. They either have no reply or have to find out the reason during sampling. With promoting date approaching, the whole team was very anxious. At Google, Timothy browsed AAK's webpage, noticed a series of articles on hydraulic manifolds, and left a message with 3 questions: 1. Does AAK have the original design capability of hydraulic manifolds? 2. What customers does AAK hydraulic manifolds supply to? 3. How long does it take for AAK to customize a set of hydraulic manifold? I felt that this is a customer with a real order, and advised that some of AAK hydraulic manifolds are customized according to the customer's drawings, some are designed according to the customer's equipment working conditions, and also helped new customers solve some difficult and complicated cases of hydraulic manifolds. Honeywell is AAK's hydraulic manifold customer for 6 consecutive years. On the second day, Timothy sent us the original design drawings of hydraulic manifold, equipment working conditions, testing videos, and the original manufacturer's hydraulic manifold pictures. I knew that this was a matter of trust. As long as the problem could be solved, the order would be awarded to AAK. Our technical team has discussed internally for 1 day, and we have the idea to optimize the oil circuit layout of the original hydraulic manifold, so that the energy consumption can be reduced by 20%. After learning about it, Timothy directly paid the development fee. After 45 days, AAK sent the hydraulic manifold samples. 2 months later, Timothy sent an email saying that the AAK newly designed hydraulic manifold had really reduced the energy consumption of their hydraulic injection molding machines by more than 20%, and the promotion was smooth. It was just taking time to place annual order. The 3 key points of this hydraulic manifold design are: 1. The oil circuit should be reasonable: we have MDTools professional software, and engineers with 17 years of industry experience to operate the oil circuit. 2. Details are the key: elbows are designed through energy efficiency correlation and smooth transition methods to minimize pressure drop, while most hydraulic manifold manufacturers use conventional elbows. 3. Process is the core: for hydraulic manifold design, we have a complete set of processes. From hole checking, wire network connection, hole network to component selection, oil circuit volume and assembly relationship are all linked. The hydraulic manifold has compact structure, small space occupation and small pressure loss. AAK hydraulic manifold, 3 advantages of design, energy consumption reduced by 20%, you can also try a small order! https://www.aakindustry.com/info-det , ail/hydraulic-manifolds-aak389
