It's almost the end of the year, and some hydraulic manifold manufacturers are lamenting that they can't make money because they are too honest. What I want to say is that any hydraulic manifold manufacturer who wants to make money must first have an honest heart, and then have a business acumen. But what's even more heart wrenching is that an honest heart and a business mind are two dimensions of things. Hydraulic manifold manufacturer AAK made a small profit with honesty. Because of honesty, it reduces the transaction costs for customers. I remember the first time I went to Frankfurt, Germany 13 years ago, at the subway station, I saw a somewhat special automatic ticket vending machine. I entered the "validity period" of my subway ticket by myself, and after purchasing it, I walked through the crowded crowd. However, I vaguely felt that I had forgotten something, until I took several subway stops before suddenly realizing that I had forgotten to check my ticket. Why did I come in without checking your ticket? In China, every subway has to check tickets and enter the station through a gate. However, there are no turnstiles here and no ticket inspectors have been seen. At the destination station, there are still no turnstiles or ticket inspectors. All passengers are heading out without any obstacles. Later on, I found out that subway stations in Germany are fully open. There are no gates, no electronic ticket check gates, and no manual ticket checks. In the bustling subway stations, there is not even a fence. The reason for doing this is because we believe in the goodwill of everyone and believe that you will consciously and truthfully purchase tickets. By relying on this method of "believing in the goodwill of the public and randomly checking the malice of the niche", the cost of public transportation is reduced. Behind the adherence to "rules" lies the spirit of contract, the essence of this story, which is to use honesty to reduce transaction costs. Both transactions between customers and hydraulic manifold manufacturers, as well as transactions between hydraulic manifold manufacturers, require overcoming the costs of "information asymmetry" and "lack of credit transmission". If you want to make money, you need to first help customers save money. Assuming a subway station spends 100,000 yuan annually on turnstiles and ticket inspectors. Assuming that hydraulic manifold manufacturer AAK can complete the "ticket inspection" at a cost of only 50,000 yuan. So AAK can say: just 60,000 yuan, I'll take care of it. The extra 10,000 yuan is the money that can be earned. The missing 40,000 yuan is the money saved for the customer. Of course, the reality will be much more complex than this simple math problem. However, hydraulic manifold manufacturers must have this logic, as long as you can reduce transaction costs, you will almost certainly make money from it. In China's manufacturing industry, whether you are a hydraulic manifold manufacturer or not, the era of good people making money is coming. This good person refers to an honest person. More and more stories are proving to us that people who are honest, trustworthy, abide by contracts, and adhere to their values can survive, and even live well. If there is any dividend in today's business world, I think it must be a value dividend. Hydraulic manifold manufacturer AAK has been constantly strengthening its business brain and adhering to an honest heart. Hydraulic manifold manufacturer AAK, with brain, heart, and integrity.

At the beginning of this year, CATERPILLAR received an order from African customer for excavators with a delivery time of 2 months, which means that all accessories must be in place within 1 month, including 600 hydraulic cartridge valves. The production time for the factory is a little more than 2 weeks. The purchaser Peter sent the order information of the hydraulic cartridge valve to all the hydraulic valve manufacturers he contacted before at the first time. More than 20 hydraulic valve manufacturers said that they could not complete the order of the hydraulic cartridge valve in such a short time, and it would take at least 3 - 4 weeks. His supervisor was not satisfied with this delivery time and asked him to find a new hydraulic valve manufacturer. After the email was sent, there was basically no sound. Peter was very helpless and worried. Peter asked Mark for help. Mark emailed AAK HYDRAULIC VALVE to ask if AAK could produce 600 hydraulic cartridge valves in 2 weeks and CC Peter, and joking at the end of the email that if AAK HYDRAULIC VALVE could not complete the hydraulic cartridge valve order, then there is no need to waste time on looking for a new hydraulic valve manufacturer. According to the drawings they sent, AAK technical department found that this was very close to the hydraulic cartridge valve supplied to a Russian customer last year, so the time in the early stage of the production of the hydraulic cartridge valve was saved. After the price of the hydraulic cartridge valve was approved, the process data could be configured on the computer on the same day and the production could be carried out the next day. 2 weeks later, 600 hydraulic cartridge valves were delivered on time, which was the first of all the accessories purchased by Peter to arrive at the company's warehouse. Peter didn't expect that the hydraulic cartridge valve he was most worried about was the first to be completed. Peter appreciated the advice from Mark and was also surprised that AAK could complete this in 2 weeks, while his previous hydraulic valve suppliers needed 3-4 weeks. Mark told Peter: 1.AAK is his most trusted hydraulic valve manufacturer. AAK can surprise him every time when the hydraulic valve order is urgent. 2.AAK has a large amount of data storage and clear classification. For hydraulic valves with relevant data, they can use the most advanced UG / SOLIDWORK software and finite element analysis method to configure process data in 2 hours, which is 3-6 times faster than that of other suppliers. 3.AAK is equipped with advanced machine tools imported from Swiss, coupled with their own modified fixtures, the production speed is accelerated and man-made errors are avoided at the same time. After listening to the introduction from Mark, Peter realized that only a good hydraulic valve supplier can make his purchasing smooth. CATERPILLAR successfully completed this urgent order. The boss was very happy when he heard the news. For Peter, who was the first to complete the purchasing, the boss affirmed his purchasing ability and praised him at the meeting. Mark told me privately that Peter was very happy because his boss gave him a promotion because of his excellent performance this time. AAK hydraulic cartridge valve has reliable quality and guaranteed delivery date. We are a manufacturer good at and focused on hydraulic cartridge valves only. Welcome to have a small try! https://www.aakindustry.com/

Caltha is from Mexico and has been purchasing hydraulic valve blocks in Ningbo China for 5 years. AAK is also one of his suppliers of hydraulic valve blocks. At the beginning of this year, their old buyer left the company and Caltha began to be responsible for the procurement of hydraulic valve blocks. The first inquiry I received from Caltha was for hydraulic valve blocks. A week later, Caltha informed AAK that the price was 17% higher and she chose another hydraulic valve block manufacturer in China. Upon seeing this big price difference, I had to give up. 2 months later, Caltha emailed me asking if the hydraulic valve blocks quoted at the beginning of the year could be completed for 5 samples within 25 days. I felt Caltha's anxiety, and after communication, I learned that the hole accuracy of the hydraulic valve block produced by the original manufacturer was not up to standard. However, the manufacturer blamed some valve hole accuracy deviations on being normal, and using electric sealant could solve the leakage. Caltha didn't want to take any risks and came back to AAK I can understand Caltha's emotions, after all, their company is a loyal customer of AAK. Our technical team started to decompose the hydraulic valve block drawings immediately. Within 25 days, AAK sent 5 hydraulic valve block samples. 2 weeks later, Caltha informed AAK that their hydraulic manifold had been tested successfully. She asked me to wait for the batch order of hydraulic valve blocks. The processing of hydraulic valve block valve holes that the original manufacturer cannot handle mainly depends on the selection of equipment and the control of accuracy. The processing of this AAK hydraulic valve block adopts the Taikan Group Processing Center, which has 3 major advantages: 1. The machining is stable, and its spindle structure adopts high-quality mihanna cast iron, with stable movement. For the same batch of hydraulic valve blocks, using the same tool and processing program, the motion trajectory of the tool is the same, and its CNC program achieves computer control, which can avoid human error. Most hydraulic valve block manufacturers do not choose this equipment. 2. High precision. The valve hole accuracy is within 0.005mm, and the repeated positioning accuracy can reach 0.003mm, and precision correction and compensation can be carried out simultaneously using CNC software. 3. High production efficiency. The spindle speed can reach 24000 RPM, and it also has functions such as automatic speed change, automatic tool change, and other auxiliary operation automation. Compared to ordinary machine tools, the production efficiency is 3-4 times higher. AAK hydraulic valve block, fast processing, and guaranteed accuracy, you can also give it a try!

Bryson is a hydraulic customer from the UK. Recently, a batch of hydraulic cartridge valves he temporarily purchased were in trouble. Because the parameters from customer were not complete, he used the same model product recommended by the hydraulic valve manufacturer instead. During testing, the flow parameters were not equal. The rated flow of the hydraulic cartridge valve was smaller than the working flow and could not be used normally, which wasted more than 10 days and the delivery time was urgent. He contacted with more than 10 hydraulic valve manufacturers. For hydraulic cartridge valves of the same model, their rated flow setting is either smaller than the working flow or close to the working flow of the system. Bryson was very distressed that no hydraulic cartridge valve has a rated flow setting greater than the working flow. Bryson found AAK HYDRAULIC VALVE. From AAK website, he felt that AAK HYDRAULIC VALVE was a little different from other hydraulic valve manufacturers. With a try attitude, Bryson actively contacted us and sent us the product picture and product model of this hydraulic cartridge valve. He just emphasized that the rated flow must be greater than the working flow and asked us to recommend the hydraulic cartridge valve of the same model, there was no any parameter information. After careful comparison, AAK engineers sent pictures and drawings of a hydraulic cartridge valve of the same model. Bryson asked us to send the hydraulic cartridge valve samples as soon as possible. On the 3rd day after receiving the hydraulic cartridge valve sample, Bryson emailed to inform that the rated flow of AAK hydraulic cartridge valve can really meet the normal operation of their current hydraulic system. Bryson expressed his curiosity that the hydraulic cartridge valve model recommended by AAK is consistent with that recommended by other manufacturers. How can there be such a big difference in the rated flow setting? For the selection of flow specifications of hydraulic valves, the settings of each factory are different. If the rated flow of the valve is close to the working flow of the system, this situation is the most economical and cost- effective, and it is also the first choice of nearly 90% of hydraulic valve manufacturers. But there may be a problem, once the working flow in the hydraulic system exceeds the rated flow, it will cause hydraulic clamping and affect the hydraulic power. It will also have an adverse impact on the hydraulic system of the valve. To be safe, when all cartridge valves are produced, AAK will give priority to the maximum flow that may pass through the circuit where the hydraulic valve is located, and the setting of rated flow is greater than the maximum flow of operation, so as to ensure the normal operation of whole system, which is also the reason why most customers prefer AAK. After knowing this information, Bryson is more convinced that AAK HYDRAULIC VALVE is different from other hydraulic valve manufacturers. It has been more than 3 months since we shipped the last goods to Bryson. Today, 200 hydraulic cartridge valves are re-ordered. Bryson told me that since AAK hydraulic cartridge valve was used, there was no hydraulic clamping problem in the hydraulic system. Their sales increased by 30% compared with the same period. The boss was very satisfied with his procurement work. The rated flow setting of AAK hydraulic valve meets the flow requirements of each system.

Kadin is from Brazil. I know that he has purchased hydraulic cartridge valves from Ningbo for at least 2 years. The peers joked that his bargain just like cutting vegetables. But a batch of hydraulic pressure control cartridge valves made him suffer. The reason may be that the price was too low. In the second half of last year, they received feedback from customer that the excavator they sold, the stick and boom will fall a short distance after stop working. Their engineers judged that the load holding function of the hydraulic pressure control cartridge valve in the system was abnormal. The original manufacturer of the hydraulic pressure control cartridge valve said that it is too difficult to optimize the function due to its price. Kadin contacted other cartridge valve manufacturers and asked that the load holding function should be 100% guaranteed, and there was no result after a week. In this way, the original manufacturer did not care about the function of the hydraulic pressure control cartridge valve supplied, and the new manufacturers also ignored him. Kadin was in a hurry. Kadin sent me an email: Can AAK 100% ensure that the hydraulic pressure control cartridge valve can maintain its load? After several rounds of communication, I learned that he had trouble in purchasing hydraulic pressure control cartridge valves. According to the video of equipment abnormalities complained by his customer and the production drawings of hydraulic pressure control cartridge valve, I fed back AAK's plan. Kadin asked for samples. After 45 days, AAK sent 24 samples of hydraulic pressure control cartridge valves. 3 months later, Kadin emailed me that it was nearly 3 months since AAK hydraulic pressure control cartridge valve was used, the customer did not find that the stick and boom were falling. His boss planned to replace the original manufacturer's hydraulic pressure control cartridge valves with AAK’s. AAK 100% ensures that the hydraulic pressure control cartridge valve has load holding function, which depends on the structural innovation. During the load holding process, the conical valve spool and valve sleeve form a conical sealing structure under the pre-compression force of the return spring. This can effectively reduce the clearance leakage through the pilot spool spool and reduce the boom drift. 1. The hydraulic pressure control cartridge valve is equipped with a pilot sliding cone valve spool and a pilot oil passage. The valve body, valve sleeve and pilot spool valve spool cooperate with each other to form 6 chambers from left to right. There is a load oil circuit in the sixth chamber, which is connected with the fifth chamber through the first orifice and the second orifice. The fifth chamber is connected with the second chamber with the main valve body through the oil inlet hole. 2. The main valve body of the hydraulic pressure control cartridge valve has a one-way valve spool and a one-way valve spool spring chamber. The third chamber is connected with the spring chamber of the one-way valve spool through the throttling groove, and the spring chamber is connected with the second oil drain hole and oil drain passage. 3. The pilot control part provides the hydraulic pressure control cartridge valve with load holding relief pressure oil through the pilot oil passage, and the fourth chamber is connected with the oil drain passage through the first and second oil drain holes. When the load is maintained, a conical sealing structure is formed between the one-way valve spool and the main valve body. AAK hydraulic pressure control cartridge valve, 100% load holding function, is not only safe, you can also try it! https://www.aakindustry.com/info-detail , /pressure-control-cartridge-valves- aak523

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
