It took 3 months and 6 proofing adjustments to match the sample quality of hydraulic pressure control valve made in Germany. Finally, AAK passed the parameter test of hydraulic pressure control valve, and our hydraulic pressure control valve was affirmed by Eaton’s company. We became Eaton’s first supplier for hydraulic pressure control valve in China. In mid October last year, an agent of Eaton came to AAK HYDRAULIC VALVE and brought a sample of Eaton hydraulic pump with a purchase value of more than US$150,000.00, asking us to make a quotation. After we checked the product parameter requirements of the artwork, we declined the quotation because AAK is only good at hydraulic valve products. Compared with its domestic peers, most of the technologies of AAK HYDRAULIC VALVE were in TOP 1-6. We thought Eaton agent would not consider us again. However, after a month, he came again and brought a Vickers Series solenoid valve with a value of up to US$200,000.00. We directly said that we are not good at this kind of products and couldn't quote. Eaton agent saw that we rejected the products that AAK is not good for 2 times, he felt that AAK is different from other hydraulic valve manufacturers, and recognized the professionalism of AAK HYDRAULIC VALVE. For the 3rd time, he brought a sample of pilot hydraulic pressure control valve with very high precision and wanted to test the parameters with our pressure test bench. I realized that Eaton agent actually wanted to test our pressure test bench with his samples. It was the first time for us to encounter such a situation, the purchaser did not test the quality of AAK hydraulic valve, but tested the equipment producing hydraulic valves first. Being satisfied with our pressure test bench, he asked if we were interested in this pilot hydraulic pressure control valve, which was a hydraulic pressure control valve produced in Germany. After learning the parameters of the hydraulic pressure control valve in detail, AAK HYDRAULIC VALVE technical team discussed the artwork of the hydraulic pressure control valve. We were 90% sure to match the quality of this hydraulic pressure control valve produced in Germany. More than 20 days later, we sent the first approval sample of the hydraulic pressure control valve. The sample comments was that there was still a 12% difference between the accuracy of AAK hydraulic pressure control valve and that of German hydraulic pressure control valve. We were required to send the revised sample again. The whole proofing and approving process have been bumpy, the parameters were continuously required to be improved. The samples have been adjusted for 6 times, finally, it met the quality of the German hydraulic pressure control valve after 3 months. Since its establishment in 2006, AAK has always put technological innovation, high-quality raw materials and advanced equipment in the first place. AAK HYDRAULIC VALVE has many high-precision imported CNC lathes and honing machines, as well as many small AAK designed fixtures and assembled special processing equipment. Each equipment has operation instructions to eliminate human errors. At the same time, we have also undertaken many hydraulic valve orders from global TOP 500 enterprises such as HydraForce. In Ningbo, it is difficult to find the 2nd such hydraulic valve manufacturer. AAK HYDRAULIC VALVE, focused on only one thing, is committed to the research and development of hydraulic valve and produce good quality hydraulic valve.

Just yesterday, I received a repeat order from Andy for a hydraulic flow control valve, which is just 3 months away from the delivery time of the last batch of hydraulic valves. The American customer Andy, started to communicate with us in 2019. Maybe it was just not the right time, we still didn't partner with each other till the beginning of this year. Because of encountering a Waterloo at the previous hydraulic valve manufacturer, he turned the tables at AAK and regained his confidence. At the end of last year, Andy purchased a batch of hydraulic flow control valves from a hydraulic valve manufacturer. Because 20% of the shipments leaked, he encountered customer claims. The old hydraulic valve manufacturer was unwilling to bear the claim or re-produce. The customer kept pushing for replacement hurriedly. The boss asked him to find a high-quality hydraulic valve manufacturer to reproduce the goods for the customer. Andy had a big headache at that time. The replacement quantity is not big, the hydraulic valve manufacturers with exquisite quality were unwilling to produce the small quantity for him. The hydraulic valve manufacturers who were willing to produce this quantity, were not able to meet the customer’s requirement about the roughness of hydraulic flow control valve. He ran into a wall everywhere, which made Andy haggard. When Andy contacted with AAK HYDRAULIC VALVE, we are willing to cooperate with her to solve this difficult problem. We tested the leaked hydraulic flow control valve sample. The reason for the leakage is the roughness of the mounting surface of the hydraulic flow control valve. According to the customer's service conditions, this roughness must be controlled at 1.0 μ M or less. Andy is very confused why 80% of the installation surface roughness of hydraulic flow control valve is up to standard, while 20% is beyond this range. The root of this fluctuation is the master's operation method, resulting in human error. The surface roughness is the depth, density, texture of the traces left on the machined surface from the action between the tool and the part surface, which depends on the master's processing technique. Andy is very clear that at present, most domestic hydraulic valve manufacturers generally control the roughness of the installation surface of hydraulic flow control valve at 0.8-1.0 μ m. The biggest problem is not stable enough. Andy also knows that only AAK controls the roughness value of hydraulic flow control valve within 0.8 μ M, which can completely avoid leakage outside the hydraulic flow control valve, because of rest assured, Andy decided to repeat the order with AAK HYDRAULIC VALVE. AAK HYDRAULIC VALVE, first determines the material according to the roughness required by the customer, and then determine the cutting process of the material according to the characteristics of the material. The workshop produces it in strict accordance with the process sheet. Technically, we abandon the traditional grinding technology and use "turning instead of grinding". Equipped with high-precision CNC lathes, we refit elastic cutting tools by ourselves, and use automatic measuring instruments. The Ra value of hydraulic flow control valve is controlled in the computer at any time, which can eliminate man-made errors and prevent the fluctuation of Ra value of hydraulic flow control valve completely.   AAK hydraulic valves, produced with ingenuity, can be purchased with confidence. At the same time, the delivery date can be guaranteed. If you have any concerns about the hydraulic valve, you might come to have a look at our website www.aakindustry.com. https://www.aakindustry.com/

How do hydraulic manifold manufacturers chat with new customers? If hydraulic manifold manufacturers can't even chat, how can they do the business of hydraulic manifolds? Whether it's a new customer at the exhibition or a first online inquiry. I remember one exhibition where the stalls of hydraulic manifold manufacturer AAK and Jiangsu Hengli were on the same aisle and diagonally opposite each other. A young girl from hydraulic manifold manufacturer AAK, who has been working for 3 years, used 5 sentences to secure an end customer. Currently, this customer purchases from hydraulic manifold manufacturer AAK every year. It is very important for hydraulic manifold manufacturers to learn how to speak up when cultivating sales, especially at exhibitions. At that exhibition, a buyer from the United States, a middle-aged person with a sense of humor, and the young girl from hydraulic manifold manufacturer AAK saw him spend more than half an hour at the Hengli booth across the street. At this point, most hydraulic manifold manufacturers' sales would say, 'You've been talking at the opposite booth for a long time, do you want to buy Hengli? Take a look at our AAK hydraulic manifolds.’ which will kill the conversation. So, what did hydraulic manifold manufacturer AAK say in their first sentence when we met this customer? Speaking must understand human nature. Let's start by praising. The first sentence of hydraulic manifold manufacturer AAK: Sir, buy Hengli, you are really very professional. The second sentence, most hydraulic manifold manufacturers' sales will say: How many years have you been purchasing hydraulic manifolds? This is a good question, but it is a question that can only be asked once we are familiar with each other. The second sentence from hydraulic manifold manufacturer AAK: Hengli is a big brand with many hydraulic categories. After the other party heard it, they were very happy. It indirectly proved that the buyer had vision. The third sentence of hydraulic manifold manufacturer AAK: but in Ningbo, the hometown of hydraulics in China, buyers are more willing to purchase AAK's hydraulic manifolds. The fourth sentence of hydraulic manifold manufacturer AAK: However, sir, AAK's hydraulic manifold will be slightly more expensive, and AAK only focuses on the production of hydraulic manifolds and valves. The fifth sentence is about the closing battle. If you make a mistake, the client will leave. So, how do we end up with the last sentence? Most hydraulic manifold manufacturers' sales would say, 'Buy AAK, give it a try, it's not wrong.'. If we say that, the new customer will become a zombie customer. The fifth sentence from hydraulic manifold manufacturer AAK: Sir, why don't you take a look at the manifolds of Hengli first? Hydraulic manifold manufacturer AAK, finally launched the customer, don't say, do you want to give it a try? Why push him out? Imagine how a middle-aged man would react to the language of a teenage girl, and he would think how expensive the hydraulic manifold of AAK is? The sales of hydraulic manifold manufacturers, whether online or offline, must learn to speak well. You should know that the greatest power of communication is to make the other party fall in love with you within 3 seconds. This is the greatest power of communication, and if you cannot achieve this, you will not be able to sell anything. Hydraulic manifold manufacturer AAK, is user-friendly, thoughtful, and good at chatting.

Kaniel is from a hydraulic equipment company in Brazil. At the beginning of this year, their customer wanted to customize an automatic small excavator and needed to purchase a hydraulic direct acting cartridge relief valve. Kaniel found a local hydraulic cartridge relief valve manufacturer for samples, and the equipment commissioning was smooth. After 1 month of use, the customer felt that the hydraulic system was lagging behind and needed to be optimized. The engineer asked Kaniel to communicate with the supplier, but there was no solution. Kaniel also contacted more than 10 hydraulic cartridge valve manufacturers, but it was fruitless. Kaniel was worried. Kaniel noticed AAK website on Google and left a message: Can you optimize the hydraulic cartridge direct acting relief valve to improve the lag of the hydraulic system? After the communication based on his system schematic diagram, combined with the original hydraulic cartridge relief valve sample anatomy, AAK engineers found the problem. By optimizing the structure and adjusting the functions of the hydraulic direct acting cartridge relief valve, and integrating the piston chamber, piston and one-way valve in the hydraulic system into the hydraulic direct acting cartridge relief valve, customers' complaints may be resolved. Kaniel paid the development cost with some doubts and waited for AAK's samples. After 50 days, AAK sent 8 samples of hydraulic direct acting cartridge relief valve. Yesterday, Kaniel informed us by email that the customer has been using the excavator for 3 months, but the original system is no longer sluggish. The next step is to place the annual order. I was asked to make production planning in the workshop in advance. I felt that there would be a big order for the hydraulic direct acting cartridge relief valve. AAK engineer optimized the original hydraulic direct acting cartridge relief valve from 3 aspects. 1. The front end of the main valve spool of the hydraulic cartridge relief valve is equipped with a one-way valve spool, a one-way valve spring and a spring seat. The one-way valve spool is provided with a damping hole. The main valve spool and the main valve spool guide cage are put into the lower valve cage, and the main valve spool spring and adjusting gasket are installed between them. The upper valve cage is connected with the lower valve cage, and the main valve spool guide cage is limited. 2. The lower valve cage of the hydraulic cartridge relief valve is provided with a front pressure port and two side pressure ports. Under the action of the main valve spool spring, the pressure port at the front end of the main valve spool forms a poppet seal. 3. The upper valve cage of the hydraulic cartridge relief valve is equipped with a piston. The screw plug blocks the end of the upper valve cage. The piston forms a piston cavity with the upper valve cage, the main valve spool guide cage, the main valve spool and the one-way valve spool. The optimized structure of the hydraulic direct acting cartridge relief valve realizes the control of secondary pressure at the same oil port, and also realizes the integration of piston chamber, piston and one-way valve. The system has a compact structure, simplified oil circuit and quick response. AAK hydraulic direct acting cartridge relief valve is multifunctional and agile.

Recently, I received the second re-order of a hydraulic pressure reducing valve from French client Chinning. I still remember when I first met Chinning in 2020, Chinning purchased hydraulic pressure reducing valves in a hydraulic valve factory and encountered quality complaints from her customers. The hydraulic pressure reducing valve was deformed in less than 3 months, and some valve spools and valve sleeves were seriously worn. More and more customers began to return goods, and the old suppliers did not cooperate with her work. Chinning had a big headache at that time, and the boss kept putting pressure on her to find a hydraulic valve manufacturer with exquisite quality as soon as possible. Chinning did not find a new hydraulic valve manufacturer very smoothly. Because her hydraulic pressure reducing valve had a special use scenario and required high hardness of materials, it was unbearable for ordinary factories. At the same time, under the environmental protection policy of 2019, many previous heat treatment and processing factories were shut down, so the supply supporting system was disrupted, and the heat treatment and processing of many hydraulic valve manufacturers could not keep up. Chinning found us AAK HYDRAULIC VALVE on Google by chance. Chinning's first question message on our website was "how does AAK ensure the service life of hydraulic valve products"? We didn't answer directly, but asked her if the hydraulic valves you purchased had the problem of deformation and rapid wear. She also replied quite frankly that she should find a hydraulic valve manufacturer that paid attention to the service life of hydraulic valves in the fastest time. I sent her several samples of hydraulic pressure reducing valve and told her that different parts of our hydraulic pressure reducing valve have different material hardness standards, and some could reach about 50-55HRC or higher. There is even no problem with 65HCR with special requirements. The service life of hydraulic pressure reducing valve is our hard index. More than one week after we sent out the samples of hydraulic pressure reducing valve, we received Chinning's email, including the drawings of hydraulic pressure reducing valve and the hardness requirements for various components. She asked whether we could produce this hydraulic pressure reducing valve? I told her that his hydraulic pressure reducing valve is not difficult, but just the working scene is some special. As long as the heat treatment process is a little unique, it could 100% ensure her requirements. The long service life of hydraulic valve is the most critical. AAK HYDRAULIC VALVE has controlled a heat treatment plant for 10 years in order to do a good job in heat treatment. The quenching and tempering heat treatment of this hydraulic pressure reducing valve material is sensitive to temperature. If the temperature is too low, the hardness is not enough, and it is easy to deform. On the contrary, it will lead to fracture. Only our proprietary heat treatment process can accurately grasp the appropriate temperature under the operation of experienced masters. AAK can also select the corresponding heat treatment process and determine the temperature range according to the different operating conditions of the hydraulic pressure reducing valve to ensure the service life of the hydraulic pressure reducing valve. Maybe there is no second hydraulic valve manufacturer with this ability in Ningbo, and the service life of AAK hydraulic pressure reducing valve exceeds 90% of its peers. The service life of AAK hydraulic pressure reducing valve is exquisite. You can also try a small order. https://www.aakindustry.com/

Cliff is a purchaser of a hydraulic valve company in the United States. He began to contact the domestic hydraulic valve industry in China a few years ago and looked for new hydraulic valve suppliers everywhere. He didn't know much about the status of China domestic hydraulic valve industry and often ran up against a stone wall. A few months ago, he purchased a hydraulic diverter valve in Ningbo, the hometown of hydraulic valves. He encountered problems and could not guarantee the delivery date. It was a trial order of hydraulic diverter valve for their company's major customer. This customer is one of the world's top 500 enterprises. If the delivery date couldn’t be guaranteed, the boss must be mad. After the communication between his boss and the customer, the customer required that the remaining 50% of the hydraulic diverter valves must be delivered within 40 days, otherwise, the order would be cancelled and all future hydraulic valve orders will not be placed neither. Cliff took this as a chance to prove himself. He spent a week constantly looking for new hydraulic diverter valve manufacturers, sending emails and making phone calls. With the situation of his last hydraulic valve manufacturer, he found that nearly most of the hydraulic valve manufacturers had low awareness of production efficiency. No matter whether the time given by the customer is enough for production or not, they just accepted the orders first. If the customer is urgent in need of goods, nearly 90% of the hydraulic valve manufacturers will choose outsourcing processing. The same batch of shipment will come from different hydraulic valve processing places, and the quality of the hydraulic valves is uneven. Cliff's other hydraulic valve suppliers in Ningbo suggested him to see if AAK HYDRAULIC VALVE has time to catch up the delivery for these hydraulic diverter valves. After knowing about the situation, I suggested that he sent us 3 samples from the shipment of the hydraulic diverter valves, as well as the drawings, detailed information and process parameters etc, and then we can check if AAK can match the quality consistent and deliver the goods in time. The AAK technical team had formed the production process and operation instructions for each process for this hydraulic diverter valve order to clean up the mess, to ensure that the production can be completed with the time frame given to Cliff. Cliff was glad that we AAK HYDRAULIC VALVE could solve this problem, and wanted to know more about how we guaranteed the delivery date. I told him that there was an old Chinese saying that if you want a horse to run fast, you must let the horse eat well. Similarly, in the production of hydraulic valves, if you want to produce fast, you must not only have good equipment, but also special equipment. AAK HYDRAULIC VALVE has many high- precision imported CNC lathes and honing machines, as well as many small AAK designed fixtures and assembled special processing equipment. Each equipment has operation instructions. The production efficiency is 30% higher than that of its peers. Besides, AAK never cheat makes small tricks and has a correct production attitude. Our production line operates 24 hours, and the hydraulic valve technicians take two shifts off. Each process has strict operation standards, and the output of hydraulic diverter valve is 30% higher than that of its peers. Because of the importance of the delivery date of this hydraulic diverter valve order, during the production process of the hydraulic diverter valve, Cliff asked us to report the production progress by video every day after work, for fear that we would delay the shipment like the last hydraulic valve manufacturer. After 25 days, the mass production of hydraulic diverter valve was completed 10 days in advance. Cliff was happy to report to his boss. The customer was also surprised to learn that the delivery was early. Cliff finally put down his heart that had been suppressed for more than 30 days. AAK HYDRAULIC VALVE never makes small tricks, and the world's top 500 enterprises are also purchasing. Do you still have any concerns? https://www.aakindustry.com/

Osborne, from Iran, sent us a PO for 500 hydraulic cartridge relief valves today. I was not surprised by this repeat order, because at the time of inquiry, he said that as long as the quality was stable, he would repeat the order twice a year. In the second half of last year, their hydraulic pump needed hydraulic cartridge relief valve. He tried samples from 2 overseas hydraulic cartridge relief valve manufacturers, but the buffering function of the hydraulic cartridge relief valve was ordinary, which affected the operation of the equipment. Osborne contacted other cartridge valve manufacturers, but failed. I also don't know how Osborne found AAK hydraulic cartridge valve. AAK had no customers in Iran before. He left a message on the AAK website: please provide me your address, I would send you a sample to copy, and the buffering function of the hydraulic cartridge relief valve must be met. After receiving his hydraulic cartridge relief valve sample, according to his hydraulic system schematic diagram, and the video of equipment commissioning, after discussion of AAK engineers, a plan was worked out. After 45 days, AAK sent 5 samples of hydraulic cartridge relief valve. 2 weeks later, Osborne sent us an email to inform that the buffer function of AAK hydraulic cartridge relief valve met their equipment requirements. The first order of 500 hydraulic cartridge relief valves was also attached. After confirming the delivery date, the full payment was made the next day. The Iranian customer was so refreshing and efficient, which is out of my expectation. The two-stage buffer of AAK hydraulic cartridge relief valve can eliminate the pressure pulse of the hydraulic system and improve the service life of the equipment by at least 20%. The optimized hydraulic cartridge relief valve, when the pressure at the oil inlet reaches the first or second pressure, the two buffer pistons can act successively to realize the opening or closing of the hydraulic cartridge relief valve, absorb the pressure pulse at the oil inlet, and eliminate the system pressure impact. Here is the structure innovation of the hydraulic cartridge relief valve that AAK works out: 1. A sliding valve spool is arranged in the valve body cavity of the hydraulic cartridge relief valve. The left end of the valve rod is sleeved with a two- stage buffer piston, and the valve rod is equipped with a compression spring. One end of the compression spring is matched with the valve spool, and the other end is connected with the secondary buffer piston, and the sliding rod of the secondary buffer piston is set with the primary buffer piston. 2. The left port of the valve body is equipped with a plug, which forms a two- stage buffer cavity between the plug and the two-stage buffer piston. The two- stage buffer cavity is connected with the oil inlet through the two-stage buffer orifice and the valve spool orifice. 3. The outer peripheral surface of the valve spool head and the peripheral surface of the valve stem cavity are in sliding coordination. The front end is equipped with a cone sealing head. The valve body oil drain port is connected with the sealing cavity where the compression spring is located, and the oil outlet is connected with the cavity where the cone sealing head is located. AAK hydraulic cartridge relief valve made in China, 2-stage buffering function, equipment life increased by 20%, you can also try it! https://www.aakindustry.com/info-detail/ca , rtridge-relief-valves-aak516

Cleveland is from a hydraulic equipment company in Mexico. He has purchased hydraulic valves in Ningbo for 3 years. We have communications for two times. He is confident, but the hydraulic cartridge relief valves he purchased last time stumped him. At the end of last year, their customer customized a hydraulic paper cutter, which requires the use of a hydraulic cartridge relief valve. The engineer asked Cleveland to purchase SUN hydraulic cartridge relief valve standard parts, and the equipment commissioning was smooth. The customer was satisfied and placed the first batch of orders. Cleveland placed the order with a hydraulic cartridge valve manufacturer in Ningbo. 6 months after the equipment was sold, the customer complained that the stability of the equipment was not as good as the prototype. After checking, it was found that the hydraulic cartridge relief valve was leaking, and the standard deviation of valve hole accuracy was only 70% of SUN's. Cleveland contacted SUN, but SUN did not have enough inventory and needed a long lead time for production. The boss was not satisfied and requested to purchase the hydraulic cartridge relief valves that benchmarking SUN. Cleveland was worried. Cleveland contacted me and told me the dilemma he encountered in purchasing hydraulic cartridge relief valves. He knew that SUN was a loyal customer of AAK Hydraulic Valves for 3 consecutive years and needed my help. My engineer told me that as long as the heat treatment of steel is in place, the standard deviation of AAK processing accuracy can completely benchmark SUN, so that I have a good idea. No comparison, no harm. I deliberately told Cleveland that AAK was only 80% confident. In order not to delay after-sales service, it was recommended for him to find another two hydraulic relief valve manufacturers that he most recognized, that is, three manufacturers made samples at the same time. If AAK sample fails, the sample cost will be returned. 2 months later, Cleveland sent an email and advised that the standard deviation of the valve hole accuracy of the 3 hydraulic relief valve manufacturers was out. The test data showed that only the standard deviation of AAK was benchmarked with SUN hydraulic cartridge relief valves. I replied that the essence of manufacturing quality is standard deviation. This is why SUN has selected AAK hydraulic valves for 3 consecutive years, and they focus on the standard deviation. Cleveland's trust in AAK was thus opened. His boss was very satisfied with the price of AAK hydraulic cartridge relief valve, which was 30% cheaper than SUN. AAK hydraulic cartridge relief valve, the standard deviation of valve hole accuracy, benchmarked with SUN, is the result of comparison and also a fact. 1. In terms of material, the valve spool of this hydraulic cartridge relief valve is made of German 20CrNi2MoV bearing steel, and the heat treatment process of "secondary quenching+cryogenic treatment+low temperature tempering" is adopted. The micro hardness is 237-247 HV, and the wear resistance is more than 3 times that of similar steel. 2. On the equipment, the valve hole of hydraulic cartridge relief valve is finished with Swiss high-precision honing machine, equipped with diamond oilstone, which is completely ground without trace. The valve hole accuracy can be within 2μm, the surface roughness is Ra0.2-0.3. 3. In terms of detection, German Diatest small micropore diameter measuring instrument is used, the minimum measurement accuracy can reach 0.1μm, and the valves are 100% full inspected. AAK hydraulic cartridge relief valve, benchmarking SUN, and saving cost for 30%, you can also try a small order! https://www.aakindustry.com/info-det , ail/hydraulic-cartridge-relief-valves- aak385

At the beginning of September this year, an IP from Brazil left a message on the website of hydraulic cartridge valve manufacturer AAK: Can you deliver 300 pcs of hydraulic cartridge valves equivalent to HydraForce RV10-22 in 25 days? I checked our inventory and there are still 110 pcs of RV10-22 in stock. Based on this calculation, there is still time. But the CITIZEN Cincom lathe from Japan is still busy in production and cannot be used to produce hydraulic cartridge valve RV10-22. I replied to Rikard: Time is a bit tight for us. We suggest that you can check with other hydraulic cartridge valve manufacturers first. 3 days later, Rikard's email arrived again: Can AAK deliver the RV10-22 hydraulic cartridge valve within 30 days? After communication, we learned that Rikard had checked with more than 10 hydraulic cartridge valve manufacturers, all of which needs more than 40 days. Currently, most hydraulic cartridge valve manufacturers are in peak production season. Without some inventory and efficient equipment, hydraulic cartridge valve manufacturers would not dare to take on this order. I felt Rikard's urgency.   The workshop master told me that RV10-22 can be processed on the CITIZEN CINCOM lathe in 3 days. If there are no other old customers who urgently need RV10-22, it should be possible to complete the delivery of 300 pcs of RV10-22 hydraulic cartridge valves within 25 days. I replied to Rikard that there should be no problem to finish within 30 days. If everything goes smoothly, perhaps we can deliver it a few days earlier. 25 days later, hydraulic cartridge valve manufacturer AAK successfully shipped 300 pcs of RV10-22, and Rikard is very grateful. I told Rikard that the RV10-22 provided by hydraulic cartridge valve manufacturer AAK not only has a short delivery time, but also has stable manufacturing quality.   The automatic CNC lathe is the most basic equipment for every hydraulic cartridge valve manufacturer, but most hydraulic cartridge valve manufacturers use the ones made in China or Taiwan. The CITIZEN CNC lathe from Japan was mainly used for precision machining of military equipment in the early stage, with advantages in processing efficiency and accuracy. It uses dual axis arranged cutting tools, which can be equipped with 14 knives at the same time, and can complete all composite processing such as turning, milling, boring, and so on at once. AAK has also upgraded its online detection function, which enables in situ detection and accuracy control of key data during the machining process. Especially the clamping process was deeply loved by the experienced technicians of hydraulic cartridge valve manufacturer AAK. We also equipped an automatic feeding device to achieve fully automated production of a single machine tool, avoiding human error. Reducing the number of clamping times, improving production efficiency, and ensuring accuracy, there is no hydraulic cartridge valve manufacturer that does not like it. Hydraulic cartridge valve manufacturer AAK, has advantages in production efficiency compared to other hydraulic cartridge valve manufacturers in China: 1. AAK adopts equipment from the Japanese military industry and also upgrades local functions. I don't know which other hydraulic cartridge valve manufacturers in Ningbo have these actions. 2. The manufacturing quality of hydraulic cartridge valve manufacturer AAK is equivalent to HydraForce and stable. AAK dares to purchase various raw materials in bulk. 3. The fully automated production of a single machine tool has a processing efficiency 40% higher than most hydraulic cartridge valve manufacturers in China. Hydraulic cartridge valve manufacturer AAK, with fast production and 3 major guarantees, you can also try it out!

Last week, on a business trip to Shanghai, a customer of integrated hydraulic cartridge valves invited me to discuss the development of an integrated hydraulic cartridge valve. They had established an office in Shanghai for 6 years. A very strange customer of integrated hydraulic cartridge valves, they never came to AAK integrated hydraulic cartridge valve factory. Every time when necessary, they asked me to go to their Shanghai office. Although it only takes 3.5 hours to drive from Ningbo to his Shanghai office, I still enjoy taking the high-speed rail. It's not only easy, but I can also meet different people in the carriage and encounter some interesting things. As soon as I sat down, I saw the passengers in the front two rows struggling to put their luggage on the rack. I could understand his difficulties and awkwardness and was willing to help. Although none of the passengers around him helped him, I quickly got up and walked over, and we put his luggage together. After returning to my seat, the word 'empathy' came to my mind. Empathy not only includes being able to understand someone else's emotions, but also the desire to help them alleviate their pain. In other words, even if you don't help in the end, your thoughts should be 'I sympathize with you and hope to help'. But if you only understand his difficulties and don't want to care, then it's not empathy. In fact, in the business of integrated hydraulic cartridge valves, empathy is also indispensable. When you encounter a sympathetic customer or supplier of integrated hydraulic cartridge valves, it is easy to reach a consensus, not only saving time, but also taking care of emotions. A few days ago, while pondering a book on brain science, it mentioned that the ability of human empathy is generated by the cooperation of ten different brain regions, collectively known as the "empathy circuit". This circuit determines physiologically how much empathy each of us can generate. The reason why a person behaves cruelly is because the empathy circuit has malfunctioned. Overall, those with strong empathy have a higher frequency of connecting with the world, and human life is not just about "surviving oneself". Everyone has their own special values for people and things, and there is a deep connection between people. This cannot be separated from our "empathy". Those who are called villains, or those who are difficult to understand, are in this state where their empathy is relatively weak. What does it mean without empathy? It means that one cannot imagine how the other person feels, what one has done, what impression they have left, or even how to communicate with others. Not only that, they never even thought that others have their own perspective on problems. In this situation, they will completely ignore the thoughts and feelings of others, only care about what they want to do, and firmly believe that their ideas are 100% correct; If someone disagrees with them, they will think that the other person is either wrong or stupid. I am most afraid of working with people without empathy. Some integrated hydraulic valve customers, without empathy, always believe that having orders is God. Integrated hydraulic cartridge valve engineers, without empathy, always think that the other party is stupid. Integrated hydraulic cartridge valve suppliers, without empathy, always think that the customer does not understand. In life, regardless of whether the people around me are willing to help those in need, I can understand their emotions and the desire to help them alleviate their pain. In work, regardless of whether the colleagues of integrated hydraulic cartridge valves have empathy or not, AAK can understand customers' emotions and have the desire to help them not waste time or step into pitfalls.

Nearly 90% of the hydraulic cartridge valve manufacturers in Ningbo can not achieve the filtration accuracy as high as 10 Microns. But AAK is 1 of the less than 10% hydraulic cartridge valve manufacturers with a filtering accuracy up to 10 Microns. Dylan came to AAK HYDRAULIC VALVE with a very special two position two-way hydraulic cartridge valve. I knew he should have encountered a problem. For this special hydraulic cartridge valve, the filtration accuracy of 10 Microns was the minimum requirement. Dylan consulted the existing cooperated hydraulic cartridge valve manufacturers, but none of them could meet the requirement. Most hydraulic cartridge valve manufacturers said that the filtering accuracy of 25 Microns is 100% no problem. Only 1 hydraulic cartridge valve manufacturer gave feedback and was 70% sure that the filtering accuracy could reach 10 Microns. Dylan directly asked me, is it really difficult for these hydraulic cartridge valve manufacturers in Ningbo to achieve the filtering accuracy of 10 microns? How can so many hydraulic cartridge valve manufacturers have said that they can only achieve the filtering accuracy of 25 Microns? I could understand his helplessness and confusion. This is because that the conventional hydraulic cartridge valve manufacturers produce hydraulic valves according to domestic hydraulic standards in China. Not only 1 or 2, but nearly 90% of hydraulic cartridge valve manufacturers, can only able to get the filter element aperture reaches 25μm. We AAK HYDRAULIC VALVE also used conventional filters at the beginning, and the filtration accuracy was also based on domestic standards. 3 years ago, a German hydraulic valve customer requested the accuracy requirement of 10 Microns, which was not only a stimulus but also a challenge for us. After more than 2 months of adjusting, we improved the process on the small sample, and adjusted the equipment parameters until it was configured to a high-precision filter and cooperated with AAK special hydraulic oil, so that the filtration accuracy of particles in the hydraulic oil could be controlled to 10μm. 1 year later, some hydraulic cartridge valve manufacturers learned that AAK had upgraded with high-precision filters and followed suit. However, due to technical constraints, many hydraulic cartridge valve manufacturers still failed to meet the standard. Under the same working conditions, if the hydraulic cartridge valves from these hydraulic cartridge valve manufacturers have a service life of 2 years, the service life of AAK hydraulic cartridge valves can be extended to 3-4 years. Dylan was surprised that we had mass produced hydraulic cartridge valves with filtration accuracy up to 10 Microns 3 years ago, but only 1 of his current hydraulic cartridge valve manufacturers could do it, and with only 70% sure. Dylan took out the drawings and asked us to send samples of this special hydraulic cartridge valve within 20 days. AAK HYDRAULIC VALVE, always has high requirements on precision.

The hydraulic directional valves produced by AAK adopts its own proprietary quenching and tempering heat treatment process, which can greatly improve the strength of the hydraulic directional valve, avoid deformation and wear of the hydraulic directional valve in the long-term use process, and significantly increase the service life. Perhaps there is no second comparable manufacturer in Ningbo like this. At most, 10% of the domestic hydraulic valve peers can compete. In order to win orders, 50% of the hydraulic valve manufacturers do not do any heat treatment to the materials for the hydraulic parts. Although some hydraulic valve manufacturers insist on heat treatment, they can only be outsourced processing due to without equipment. There are also 20% of hydraulic valve manufacturers, who do not have a fixed outsourced processing place, so it is impossible to ensure the heat treatment quality, not to mention the stability. Due to these common problems in the hydraulic valve industry, the hydraulic valve will show many problems after being used for a period of time, such as product deformation and wear. Once the hydraulic valve is deformed, it will easily to be blocked and the service life of the hydraulic valve will be greatly shorten. 5 months ago, Mike, a hydraulic valve customer in the United States, came to me. He had been confused, since 2019, there have been continuous customer complaints about the hydraulic directional valve he purchased. All the complaints are that after the hydraulic directional valve has been used for a period of time, some hydraulic directional valves are deformed and some hydraulic directional valves are worn quickly. Obviously, there is a problem with the heat treatment of the materials used in the hydraulic directional valve. Since 2019, due to the environmental protection policy, the domestic heat treatment plants have been vigorously rectified, and there are much fewer processing places. 50% of the hydraulic valve manufacturers do not have a place to do heat treatment to the raw materials. Even if heat treatment is done, 20% of the hydraulic valve manufacturers have to change the processing places for each external processing. I sent him several samples of AAK hydraulic directional valve and told him that the material hardness of our hydraulic directional valve has not changed, which always can reach about 50-55HRC or higher, and there is no problem with the special requirement of 65HRC. He didn't know that the service life of hydraulic valve is our hard index. 3 months ago, Mike issued a test order for the hydraulic directional valve. Each different part of the hydraulic directional valve is marked with different hardness requirements. He also wants to know how AAK ensures the service life of the hydraulic directional valve. To get a long service life of hydraulic directional valve, heat treatment is the first and most critical step. In order to do a good job in heat treatment, AAK has held a heat treatment factory for 10 years. The quenching and tempering heat treatment of hydraulic valve materials is sensitive to temperature. If the temperature is too low, hardness is not enough and easy to deform. On the contrary, it will lead to cracking. Only our proprietary heat treatment process can accurately grasp the appropriate temperature under the operation of a master with more than 6 years of experience. AAK can also select the corresponding heat treatment process and determine the temperature range according to the different working conditions of the hydraulic valve to ensure the service life of the hydraulic valve. AAK hydraulic directional valve has a service life of more than 90% of its peers, you can also have a small try. https://www.aakindustry.com/

Uberto is from a hydraulic equipment company in Mexico and has been engaged in the procurement of hydraulic components for 2 years. At the end of last year, their customer customized a hydraulic power unit, and the hydraulic manifold of it was made by a local hydraulic manifold manufacturer. The commissioning of the equipment was smooth, and the customer was also satisfied, but the price of the equipment was more than 15% higher than that of similar products in the market. The company requested to optimize the hydraulic manifold to reduce the cost, but the original hydraulic manifold manufacturer has no idea. Uberto found AAK website on google. According to the background trace, he stayed for more than 10 minutes and left us a message: Can AAK optimize hydraulic manifold to reduce costs? After communication, we learned that the customer disliked the high price of their equipment. According to the schematic diagram of the hydraulic system provided by him and the original hydraulic manifold drawing, after discussion, AAK technical team proposed an optimization scheme, which is to form a combined hydraulic manifold, reduce the installation difficulty and cost. When Uberto's engineers learned that AAK had an optimized hydraulic manifold scheme, and that the cost would be reduced by 30%, they expressed doubts, then there was no further news. 2 weeks later, Uberto suddenly requested AAK to make samples for the hydraulic manifold and paid the development cost. After 50 days, AAK sent 3 hydraulic manifold samples. Last week, Ubertor emailed that the hydraulic power unit with AAK hydraulic manifold had been installed on the equipment and had been tracked for 4 weeks. The function and stability of the hydraulic power unit is the same as the original hydraulic manifold. Their customer decided to purchase their hydraulic power units. The boss was very satisfied and their engineers were also impressed. The combined hydraulic manifold optimized by AAK is a modular, configurable and open hydraulic manifold. It abandons the traditional mode of using "single element" combined circuit, avoids overlapping functions and structures, and reduces control valves, which is the key to significantly reduce costs. 1. The four-way hydraulic manifold control system is composed of pilot control valve group, 4 two-way cartridge valve control components, manifold blocks and connectors. It has 4 main channels, several pilot control channels, and 2 external mounting surfaces, which greatly reduces components. This is a technical activity. 2. The top of the hydraulic manifold is provided with a boss, which is a boss type step surface composed of the boss and 2 parallel finishing planes. The mounting surface of the convex part of the boss is installed with 2 groups of pilot control valve groups, and the mounting surface of the plane parallel to the boss plane is installed with a two-way cartridge valve. 3. The left and right sides of the hydraulic manifold are used to connect the high pressure input port and low pressure output port of the main channel as well as the pilot control channel, and the rear side is used as the connection port of the high pressure output port of the main channel. The installation of components is convenient and fast.
