China Hydraulic Valve

AAK hydraulic valve blocks are processed with compound cutting tools, and the production efficiency is nearly 50% higher than that of peers. At the same time, the precision of hydraulic valve blocks is also improved by 5%. AAK completed the urgent order of 1,000 hydraulic valve blocks in only 30 days, while most hydraulic valve block manufacturers can't control the processing technology of compound cutting tools. German customers are also attracted by it. It's a little strange that since the second half of last year, many inquiries about hydraulic valve blocks have an urgent delivery date. They need to be shipped within 20 days or finished within 30 days. For non-standard hydraulic valve blocks, from production drawing design, sample, life test, production to delivery, the vast majority of hydraulic valve block manufacturers need 45-60 days. But this is desperate for the customers with urgent order of hydraulic valve blocks, and Bach in Germany is one of them. Bach wanted to purchase 1,000 pcs of hydraulic valve blocks a few weeks ago. His customer requested that the goods be delivered to Germany in 50-60 days, but the quotation of the local factory in Germany exceeded his budget. He could only find the manufacturer of hydraulic valve blocks in Ningbo, that is, goods need to be shipped in 30 days. Bach contacted nearly 20 hydraulic valve block manufacturers, but none of them can complete the production of 1,000 hydraulic valve blocks in 30 days. A few days ago, we received Bach's message on AAK website (www.aakindustry.com): I saw an article on B2B that "AAK processes hydraulic valve blocks with compound cutting tools, and the delivery time is 30 days faster than peers". Can AAK complete non-standard hydraulic valve blocks in 30 days? After communication, I learned that Bach was troubled by the delivery date of hydraulic valve blocks. I directly told him that the 30 days of lead time for 1,000pcs of hydraulic valve blocks is enough for AAK. AAK adopts the compound cutting tool processing technology that most hydraulic valve block manufacturers can't control, that is, combining two or more similar or different types of hole processing tools into a special composite tool. In the process of machining, reduce the tools required for machining X, Y, V and U partial views, and complete the process combination of multiple processes such as drilling, reaming, spot facing and boring. At the same time, one tool can simultaneously process threaded bottom holes, 45 �°, 15 �°, R0.1 chamfering and external counterbore, which greatly improve the processing efficiency and have the characteristics of high efficiency, high precision and high stability. This is the "trump card" of AAK to improve the production efficiency. The production efficiency is nearly 50% higher than that of its peers. At the same time, the precision of hydraulic valve blocks is also increased by 5%.

Since the epidemic, many work forms have changed. Whether working at home or in 3 + 2 mode, it tells us that the future organization will be a new mode, and the manufacturers of hydraulic valves are no exception. My understanding of the future factory is that the factory is a factory, only a limited production department. Just like our hydraulic valve factory in Cixi, it has only one function - producing hydraulic valves, which is the "1" in the "6 + 1" industrial chain. For hydraulic valve industry, "6" in the "6 + 1" industrial chain refers to: 1) hydraulic valve design and innovation, 2) procurement (raw materials, or semi-finished products), 3) warehousing and transportation, 4) order processing, 5) hydraulic valve sales, 6) after-sales and service; "1" refers to the production of hydraulic valves. A few years later, our hydraulic valve factory is no longer crowded. The hydraulic valve workshop is either the sound of machine tool cutting metal, or 2-3 masters who give machine tool instructions or maintenance. Small bosses shouldn't care about the macro-economy, which has nothing to do with you and me. Just like me, you can focus on a subdivided field of hydraulic valves, and it is enough to achieve the top 1% in this field. Please note, it is not Top 1. AAK has always focused on the single product of hydraulic valves. It works online for 4 hours a day, which is 7,300 hours in 5 years. It has reached the top 1% of the subdivided field of hydraulic valves. If your enterprise can't reach the top 1%, add another 2 years and reach 10,000 hours in 7 years. You must be the top 1%. Seven years is a watershed for many enterprises. Seven years later, if your enterprise is still "poor", there must be problems in your cognition, thinking and method. The "conspiracy theory" on the Internet makes those with simple brains look less simple. Online "knowledge fast food" makes those who never "think deeply" look like they can "think deeply". This is not a good way to do the hydraulic valves. Online, our circle is no longer restricted by the actual conditions and regions, and it is easier for those with similar interests to gather together. Although you may be in completely different industries, or even you and I are far from each other, the same combination of "cognition" and "Three Reviews" makes you attract each other. AAK hydraulic valves adhere to our three views and the top 1% of the industry. AAK hydraulic valves adhere to a group of people, a lifetime and one thing, let each user use AAK hydraulic valves without any trouble. AAK hydraulic valves adhere to the principle of integrity, does a good job in the business of AAK hydraulic valves, and sincerely treats the customers who purchase each hydraulic valve. Let more customers use good hydraulic valves with real materials without wasting money. AAK hydraulic valves, top 1%, welcome to give it a try. AAK HYDRAULIC VALVES (194) 2022-04-12

AAK HYDRAULIC VALVE has grown for 15 years, as one in the group of hydraulic valve suppliers in Ningbo. The supply of hydraulic valves has reached its peak and trough, but we always remember that we are a hydraulic valve supplier. I believe that as long as we don't give up and do hydraulic valves all our life, AAK will become the best hydraulic valve supplier. Our hydraulic valves have been supplied to 3 of the world's top 500 Enterprises. There may be no second such hydraulic valve factory among the Ningbo based hydraulic valve suppliers. Angelo, an American customer from top 500 enterprises, was introduced to AAK HYDRAULIC VALVE by a friend. He needed to make a sample of a hydraulic pressure valve for his customer to test new equipment. According to Angelo, he successively contacted no less than 10 hydraulic valve suppliers. After 2 rounds of elimination, 3 hydraulic valve suppliers were selected for proofing. The hydraulic pressure valve samples produced by 3 hydraulic valve suppliers had some leakage, vibration and noise under different working conditions. His customer was not satisfied with the samples from these hydraulic valve suppliers. The customer asked him to find an American hydraulic valve supplier. Considering the high cost of American hydraulic valve suppliers, he still wanted to try the hydraulic valve suppliers in China. If a qualified hydraulic valve supplier still couldn't be found, he had to give up. Due to equipment limitations, if the requirements of working conditions are relatively high, the hydraulic pressure valves produced by most China hydraulic valve suppliers will have the problems mentioned above. The fundamental reason is that the accuracy of hydraulic pressure valve is not enough. Generally, the ordinary hydraulic valve suppliers cannot do this high-precision hydraulic pressure valve. The accuracy of hydraulic pressure valve has always been a hard index of AAK. AAK is not only equipped with high-precision machine tools, but also with 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 to eliminate human errors. For the coarse grinding in the early stage to the fine grinding in the later stage, at least 3 times of repeated debugging and testing shall be carried out until the accuracy index requirements are fully met. In Ningbo, it is difficult to find a second such hydraulic valve supplier. Angelo realized the difference between AAK HYDRAULIC VALVE and other hydraulic valve suppliers. A week later, we delivered the samples according to the product accuracy required by Angelo. His customers recognized the accuracy of the hydraulic pressure valve in 3 days after receiving the samples. Angelo was satisfied and said that AAK would be his preferred hydraulic valve supplier in Ningbo.

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 owner 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. 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 ensure her requirements. The long service life of hydraulic valve is the most critical.

Kaden, a hydraulic valve purchaser from the United States, has been successfully purchasing hydraulic valves from China in recent years, and his boss also attaches great importance to him. Last month, at the original hydraulic valve manufacturer, he placed an order for a hydraulic valve block with multi-stage valve spool hole. The manufacturer confirmed that there was no problem and submitted the PPS of hydraulic valve block for 3 times, but the accuracy of valve spool hole was not approved every time. This made his customer very unhappy and thought it was a waste of his time. If the 4th hydraulic valve block sample still could not be approved, the order would have to be cancelled. The boss was also surprised and asked him to solve it within a time limit. Kaden felt unprecedented pressure. Kaden realized that the current hydraulic valve manufacturer must be replaced and contacted with no less than 10 hydraulic valve manufacturers. No factory has the ability to accept the order of this hydraulic valve block. Because the valve spool hole of this hydraulic valve block had a multi-stage structure, the accuracy was difficult to be controlled, the diameter tolerance of the valve spool hole of the hydraulic valve block was small, and there were many accuracy requirements such as coaxiality. Kaden was a little frustrated and seemed to have to give up. A hydraulic valve manufacturer in Ningbo told Kaden that the multi-stage valve spool hole must be processed with URMA reaming technology, and AAK hydraulic valve had this technology and could have a try. Kaden contacted us AAK hydraulic valve, directly indicating that he was introduced to us by a hydraulic valve factory, now he was in trouble with a special hydraulic valve block. He sent us the drawings and parameter requirements of the hydraulic valve block, and asked whether we were sure to be able to produce this hydraulic valve block. After analyzing the drawings, the technical team of AAK hydraulic valve told him that we would send the samples of hydraulic valve block directly to him for testing after 12 days. If the accuracy of hydraulic valve block met the requirements, we could produce it. Kaden requested that the PPS of the hydraulic valve block must be good so as not to completely disappoint his customer. On the 5th day after receiving the sample, he was very happy to inform us by email that after two tests by his company and his customer, AAK's hydraulic valve block met the requirements. He asked us to prepare materials and production can be started once other details are determined. AAK hydraulic valve URMA reaming technology adopts guide bar support to ensure correct tool position and rigorous cooling to ensure tool lubrication. Especially for multi-stage valve spool hole, or valve spool hole with small diameter, we have our own processing experience. This is rare in Ningbo hydraulic valve manufacturers.

hydraulic relief valves . purchased a batch of hydraulic relief valves for crane system in because the original supplier was not able to meet the delivery. He sent an email last week saying with hydraulic relief valves, the stability is 8% higher than that of the original supplier, and there is almost no external leakage. This surprised him. The use experience of hydraulic relief valves has benchmarked with their previous local hydraulic relief valve manufacturers The vast majority of hydraulic valve bodies are made of nodular iron, vermicular iron and gray iron and cast with resin sand as the molding medium. Therefore, there is sticky sand in the casting, which is easy to pollute the oil system and block the valve and filter, which is the key factor affecting the stability of hydraulic relief valves. Most of the common sand cleaning methods of hydraulic relief valves used in the industry are shot blasting and electrochemical sand cleaning, all of which have limitations. 1. Shot blasting can not completely remove the sticking sand from the valve hole with complex structure and small oil passage, which is easy to affect the tightness and product accuracy, and is not conducive to the stability of the hydraulic relief valves. 2. Electrochemical sand cleaning can relatively remove the sticky sand in the narrow oil passage, but it has high energy consumption, high operation intensity of workers, easy to have human errors, can not completely remove the sticky sand, and is not conducive to the stability of the hydraulic relief valves. Improving the quality of hydraulic parts processing process, improving the cleanliness level and ensuring the stability of hydraulic relief valves has always been the hard index of hydraulic relief valves. Auxiliary processing of hydraulic parts mainly includes: sand cleaning of valve body, deburring or residue treatment of parts and cleaning of hydraulic parts. How does do the sand cleaning of hydraulic relief valves technical team has continuously improved the sand cleaning process of hydraulic relief valves after years of technical improvement. For the sand cleaning of small complex castings, has its own unique sand cleaning 5 methods, namely: artificial aging - Pickling - rinsing - rust prevention - ultrasonic cleaning. Artificial aging is used to reduce the binding force between the casting and sand, acid pickling is used to remove the oxide skin at the joint between the sand and the casting to peel the sand from the casting, and then the explosion of compressed air during ultrasonic cleaning is used to peel off the sand, so as to achieve the purpose of sand cleaning. has its own unique advantages of sand cleaning 5 methods: (1) it is less affected by the casting structure; (2) it is

new hydraulic relief valve. The drawings of the hydraulic relief valve were sent 1 month after the confidentiality agreement was signed. The customer requested that if we were not able to develop it, they would witness us destroy the drawings and documents of the hydraulic relief valve by video. It's the first time for this customer to be so formal After receiving the drawings of hydraulic relief valve, we knew that it was to match with a set of aerospace equipment developed by a world top 500 enterprise in the engineers reviewed the drawings for 3 days and still didn't write the sample program. This hydraulic relief valve is not only small in size, but also has material requirements, machining accuracy requirements and use frequency requirements that exceed the parameter requirements of the hydraulic relief valves we have seen. We estimated that the overall development When we mentioned and give you 1 year of time. If the development is successful, you can wait for the order of hydraulic relief valve. If the development fails, this will be deducted from the payment for in the future. to say that the customer will prepay for the development cost of the hydraulic relief valve, but if it fails, we will need to refund it by deducting from the future payment gradually. I did not hesitate to reply to the email and was willing to try to develop this hydraulic relief valve. hydraulic relief valve development would be counted as the contribution of the technical team, and the failure would be counted as mine, because I can't fail to live up to the customer's support for our development. Some people in can not understand how this could be a kind of support. Maybe he didn't think about a question, that is, what would the mentality of the technical team be without customer support Behind these are two completely different ways of thinking. One is that if you haven't done it yet, think about failure first, think about whether there is a bottom plan first, and if not, don't do it. There is also a way of thinking, which is to think about how to start first. If conditions permit, start working first. The difference between these two ways of thinking is not just the difference between conservative and radical, but whether people are the key factor to create value. With the starting money, the hard work of the technical team and the best logistics

When I opened the mailbox this morning, I saw an from , which should be a re-order for the hydraulic relief valve, because he asked about the durability of hydraulic relief valve spool last week. Opening the , it is indeed the need for purchasing a large number of 420 hydraulic relief valves, and requiring 3 years of quality guarantee. is a purchaser of . 3 years ago, a customer of his company complained that the crane was easy to depressurize during work, resulting in the inability of the crane to bear the force. Especially after the working temperature reaches 55 C, the pressure cannot go up. Field engineers believe that this is a problem of the hydraulic system, such as low pressure regulation of the hydraulic relief valve, wear of the hydraulic system, or oil pollution. No abnormality was found after inspection. Finally, it was determined that the fault occurred on the hydraulic relief valve. After disassembling the hydraulic relief valve, it was found that the cone valve spool was worn, affecting the sealing of the hydraulic system, so the oil pressure could not rise. The customer does not understand why the valve spool of this hydraulic relief valve is worn after less than 2 years of use. The customer requested to replace with a batch of hydraulic relief valves with durability of more than 3 years and use them on these 12 faulty cranes. At that time, contacted more than 10 hydraulic relief valve manufacturers and got reply that the warranty could not be achieved for 3 years. Some hydraulic valve manufacturers replied that they only have 50% confidence. This result embarrassed Bruce. The customer requirements for the hydraulic relief valve could not be implemented, how he should explain to the owner. I received message from on the of can really provide a 3-year warranty hydraulic relief valve I replied directly: just give it a try then you will know. I can't make money with the trial orders of several samples, and you can't lose money. Maybe was stimulated and sent us the test order the next day for 4 hydraulic relief valves. also frankly told that two other hydraulic valve manufacturers would also try the order at the same time. Their plan is that each factory will be tested for 4 samples, with a total of 12 hydraulic relief valves to meet the urgent needs of customer first. About 2 years after the samples were sent, we received from again for another trial order of 8 hydraulic relief valves. I felt strange and thought that they actually didn't have big quantity order for hydraulic valves. Until last week, from his email, we learnt that they had tested the hydraulic relief valves provided by for 3 years. Indeed, 3 years later, hydraulic relief valves still worked normally, and the hydraulic relief valves provided by the other two manufacturers had faults in less than 2 years.
