Recently, the same model of hydraulic valve spool, has higher precision and stronger sensitivity than its peers.
This is a good question. I smiled and said you may not have a comprehensive understanding of hydraulic valve. For all types of hydraulic valve spools, is subject to strict quality control. Under the condition of ensuring that the spool is suitable for the service conditions, we will select the most appropriate tool steel 40Cr, Cr12MoV, 12CrNi3A, 18crniwa and GCr15, etc according to the customer's parameter requirements and service scenarios. 6 major processing processes and 6 major parameters are used. This technology has led the industry, we are not satisfied with these static data, but also need dynamic spool.
Since the valve spool needs to move in the valve body, the clearance between the valve spool and the valve body should not only ensure good sealing, but also ensure small movement resistance. Therefore, the matching clearance between the valve spool and the valve body is the top priority affecting the use of the valve spool. The following are the tolerances and matching clearance dimensions of the valve spool and the valve body produced in large quantities by in the actual production process
Diameter Valve body tolerance Spool tolerance Minimum clearance Maximum clearance
6mm 0.006mm 0.004mm 0.0025mm 0.0125mm
6-12mm 0.0075mm 0.005mm 0.0050mm 0.0175mm
12-20mm 0.01mm 0.006mm 0.0050mm 0.0233mm
20-25mm 0.0125mm 0.0075mm 0.0125mm 0.0325mm
When the reciprocating or rotary valve body is matched with the valve spool, we generally use the minimum clearance, but the specific processing parameters should also be determined according to the customer's parameter requirements and use scenarios, so as to ensure that the hydraulic valve does not have any leakage, valve stuck and other unexpected working conditions.
During the processing and manufacturing of valve spool, also strictly considers the following aspects, and will check and test each valve spool when necessary, so as to ensure the high quality and reliability of valve spool.
Hydraulic power on hydraulic spool
Pressure and flow characteristics of hydraulic valve spool
Flow coefficient of hydraulic valve spool
Leakage of hydraulic valve spool
Stability of hydraulic valve spool
Vibration of hydraulic valve spool
Cavitation of hydraulic valve spool
After listening, they admired rigid attitude and trusted the quality of hydraulic valve more. Using hydraulic valve is reassuring, so has always been their preferred hydraulic valve supplier in .
hydraulic valve sticks to itself and high quality control. You can also have a small try
AAK HYDRAULIC VALVE (114) 2021-12-08
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.

90% of the people do not know hydraulic valves. How does persist for 13 years To be sure, there are many small and medium-sized factories with their own proprietary technologies , such as industrial products manufacturers with their own traditional technologies such as hydraulic valves. It is unlikely that will in 30-50 years, although consumables are gradually being replaced. Therefore, I am optimistic about hydraulic valve manufacturers, especially those with some proprietary technology. Over the past 13 years, has adhered to 3 lines: R & D, innovation and manufacturing capacity: 1. Hydraulic Valves maintain the trend of being specialized and strong. I call it both specialized and strong. Instead of giving priority to the development of manufacturing scale, we invest money in the research and development of hydraulic valves, spend time on the innovation of hydraulic valves, and spend energy on the manufacture of hydraulic valves. Most of the manufacturing industries have learned too many lessons from big to die. 2. focuses on the R & D and innovation of hydraulic valves. It focuses on both technology and quality, and strives to be strong on both sides. Its quality benchmarks the international first-line hydraulic valve brands. The performance and function of some hydraulic valves have exceeded the domestic head hydraulic valve manufacturers, especially in the vertically segmented niche market, such as high-pressure hydraulic valves. 3. Although the production scale of Hydraulic Valve maintains the original situation, there is still room for urgent orders and special orders of old customers. For industrial products, especially machine parts such as hydraulic valves, in marketing, you will find that it has nothing to do with the theories of Trout and Kotler. hydraulic valves adhere to: Focus on large hydraulic valve products and become our own core competitiveness. The manufacturing quality of hydraulic valves, the price positioning of hydraulic valves, and the target customers constitute a triangle of a manufacturing enterprise. Marketing, promotion and sales constitute a triangle of hydraulic valve business. I have always called on hydraulic valve manufacturers to improve the material grade and produce high-quality hydraulic valves, but few hydraulic valve manufacturers follow suit. Why Because the manufacturers of hydraulic valves have extremely fierce price competition, even if you do it, you may not be able to make money after all the hardships. However, hydraulic valves are used by 7 of the world's top 500 companies. For 9 consecutive years, hydraulic valves have been hydraulic valves. Moreover, hydraulic valves never do market common quality, price comparison and credit business. In the face of such a competitive hydraulic valve market
Is scientific research and innovation one way or two different ways hydraulic valve analyze it like this In the field of industrial products, has made rapid progress in recent years, with many proud scientific research achievements and patented technologies. In the hydraulic valve industry, hydraulic valve manufacturers have also begun to export, in these two years. Each hydraulic valve manufacturer has Many hydraulic valve manufacturers confuse the concepts of scientific research and innovation. Generally speaking, hydraulic valve scientific research is to convert money into hydraulic valve knowledge, which is a department that spends money, while hydraulic valve innovation is to exchange knowledge for money and create wealth for enterprises. They cannot be confused. Some scientific research institutions have only completed scientific research, but rarely completed innovation. It is a pity that some hydraulic valve manufacturers in the world have invested a lot of money in research and development, but they are only immersed in theory and have not become innovative pioneers in the industry.
The economical, efficient and reliable hydraulic manifold block design convinced Achilleas completely Achilleas comes from a Greek hydraulic equipment company. One of their rollers was complained by users because of oil leakage. After sales personnel found that there was a large gap in the valve block used for hydraulic manifold, which was the root cause of oil leakage. After further disassembling the hydraulic manifold, it was found that there were cracks in the lower left and right corners of the valve block. They thought that the problem can be solved by replacing the valve block. However, after 2 months of construction, the old problem was happened again. The engineer asked Achilleas to consult the original hydraulic manifold manufacturer. The manufacturer was not sure why the valve block broke within 2 months. Achilleas was helpless. Achilleas realized that he could only contact for help, because he also sent the inquiry for this hydraulic manifold to before. At that time, proposed to modify the oil circuit and hydraulic valve selection, but it was not accepted by their engineers. I was not surprised to receive his email. At the inquiry stage last year, our engineers found that there was an energy conflict between the oil circuit aperture of the hydraulic manifold and the selected hydraulic valve, resulting in the frequent instantaneous pressure rise of the hydraulic system. In particular, the oil circuit wall thickness at the left and right lower corners of the valve block is not enough, so it is not surprising that the valve block is cracked. This time, Achilleas didn't go to their engineers to verify. redesigned the oil circuit, re selected each hydraulic valve, and sent the hydraulic manifold block sample after 30 days. Last week, Achilleas sent an email saying that after replacing with sample for such a long time, there was really no problem. Moreover, the total price was saved by 20% compared with the original one, and the customer feedback that the action sensitivity was also improved a lot. This time, even their engineer also suggested that the boss should give the design and production of the hydraulic manifold block to in the future. He also wants to know why is so good I told him that the most important thing in the design of the hydraulic manifold block is to determine the operating parameters of the hydraulic system, understand the requirements of the system for the maximum working pressure and maximum flow, and reasonably design the oil circuit. Secondly, the pressure drop of the valve must be considered to ensure that the pressure drop through the pressure valve, flow valve and directional valve is not too high, which will affect the load action and cause the pressure problem of the valve block. has more than 20 years of industry experienced professional engineer from , who have unique experience in the design of hydraulic manifold blocks, especially
hydraulic valve has a bench department without KPI, but it is a special team in my heart hydraulic valve also has a similar department, but it is called bench department. This department has no short-term KPI and no KPI catch-up. Like an engineer's paradise, hydraulic valve engineers dare to keep trying and optimizing with such an environment. In hydraulic valve, the sales department makes today's money, the production department makes tomorrow's money, and the bench department makes the day after tomorrow's money. Conversely, the bench department is wasting today's money, spending tomorrow's money to do development for the sake of hydraulic valve strategy and the future of hydraulic valve, although the future is not clear, in my mind, they are the "special team" of hydraulic valve. Making high-quality hydraulic valves can only be driven by technology. A combat team composed of several people can anchor and conquer a technical direction. The subdivided STG focuses on innovative solutions for hydraulic valves. There has never been a shortcut or a fast track for the scientific research of hydraulic valves. Only when we settle down to do things, can we make every step steady. The reason why science and technology in this world can be developed is precisely because of the engineers' persistence, which is a long-termism and a bench spirit. hydraulic valve is used in aircraft. It sounds very powerful. But it's really hard to do. Sometimes you can't see the way. Sometimes, there are many roads in front of you. Fortunately, hydraulic valve chose the right path. Even if the road is tortuous, even if the road is very hard. But the right way is never far away. The bench Department of hydraulic valve has to make a hard hit on this road every day. Diligence is a way to explore talents and a necessary condition for success. engineers have experienced for many years. It is not difficult to combine, mutate and graft some hydraulic valve structures to create some new hydraulic valves. Instead of making some so-called patents that can't create any value for no reason, it's better to use your limited life to do something that can leave a mark on this beautiful planet. At that time, when I am old to die, on my deathbed, I will think that I have lived for so many years and made so many devices to run on the earth, which is enough to make me smile in the underworld. Bless the engineers of hydraulic valve. May you have the bench spirit to conquer one mountain after another. I also wish hydraulic valve a happy journey. hydraulic valves, the right way, never afraid of far.
defines total quality from 4 aspects, which is the first time in the hydraulic valve industry I want to know how defines the quality of hydraulic valves. I specially checked the IP, which is an engineer from an engineering company listed in the I thought for half an hour. To define a category, it must be comprehensive. What are the total quality of hydraulic valves How much do we understand the quality of hydraulic valves First, don't check the encyclopedia, , or hydraulic valve academic, but focus on hydraulic valve common sense. In common sense, how do you understand the quality of hydraulic valves, because our users also understand the quality with common sense. Friends who have read science and engineering know that there is a very famous management in What is carried forward is in . The well-known enterprises implement total quality management. Almost all those engaged in manufacturing industry know total quality management, but few mention total quality. Some people say that total quality management has talked about total quality Wrong, total quality management does not talk about total quality, only about management. For the total quality of hydraulic valves, I have defined 4 kinds of quality. The 1st is the manufacturing quality of hydraulic valves, the 2nd is the service quality of , the 3rd is the functional quality of hydraulic valves, and the 4th is the performance quality of hydraulic valves. The manufacturing quality of hydraulic valves is now benchmarked with the international first-line brand, and the future is to surpass the international first-line brand. Especially in a subdivision field, such as high-pressure hydraulic valves, we should achieve top 1%. 1. has been hydraulic valve ODM manufacturer for 3 of the world's top 500 for 10 years. The quality control process is strict and self-implementation is more strict than ISO certification system. 2. has high-precision machine tools imported GF high-precision CNC machining center and GILDEMEISTER turn milling compound machining center. 3. has a full-time material engineer to check the selection of materials, which is responsible for screening, comparison, testing new materials connected with the Research Institute. technical team has engineers from the world's top 500 hydraulic valve enterprises. They have their own experience in production drawing design, programming and production line quality control. Service quality of : 1. provides 24-hour responses, 48-hour solution plans and 72-hour problem solved before, during and after sales. Our peers dare to think but dare not to do it.
How do you understand mindfulness of be a man of credit and integrity to make hydraulic valves Today, a message on hydraulic valve website mindfulness of be a man of credit and integrity to do hydraulic valves. What does this mindfulness mean I checked the IP of this visitor deliberately because I'm not sure whether it's a hydraulic valve customer or a hydraulic valve peer, but I think it should be a foreign hydraulic valve manufacturer. Because of the differences of it is a little difficult to express it in English for the moment. Mindfulness is simply understood as which means praising a person's good character. But for the understanding of morality, everyone's standards are different. I consulted In the context of someone explained that which means intact. That is to say, a person who maintains consistency This marks a benchmark. What kind of person is Integrity It is a person who matches deeds to words, does what he says and is integrity. In hydraulic valves, take small things as example, I make an appointment and don't be late; Officially speaking, if you sign the hydraulic valve contract, you will abide by it; Take production as an example, the quality of each hydraulic valve is equal to or better than the confirmed parameters. hydraulic valves, combination of words and deeds. It dedicates itself to the production of hydraulic valves, never cheating with small actions. The ethereal thing of moral character becomes clear in hydraulic valves. I remember a few years ago, an hydraulic valve customer to visit hydraulic valve. may not be a big moral flaw, but it at least proves that such a person is not at least an integrity person, which conflicts with our hydraulic valve culture. hydraulic valve, mindfulness of be a man of credit and integrity to make hydraulic valves.
For a hydraulic valve manufacturer, if you produce hydraulic valve standard parts like your peers, without your differentiation or difference, you can only rely on a set of hard technical indicators of quality to make the market. I think this is the hard indicator of hydraulic valve manufacturing industry. The first thing for a hydraulic valve factory is quality positioning. I ask our engineers, workshop directors and technicians, even apprentices, to benchmark the global first-line hydraulic valve brands in terms of quality awareness, at least surpassing the quality of domestic first-line hydraulic valves. Otherwise, you are not suitable for hydraulic valve production in AAK. If you don't get the masterly skill really masterly, you are not qualified to enter the hydraulic valve market. With masterly skill, you have the confidence to produce orders for hydraulic valves from the world's top 500 enterprises. â??Zhiliangâ??, also known as â??Pinzhiâ??, is both quality in English. I don't understand why some hydraulic valve manufacturers have no differentiation, and the quality and technical indicators are strong neither. What does it depend on to win the world? Unless you cheat. Each industry has its own quality standards. At the same time, each product has its own enterprise quality standards, and the peers are different. This is the quality positioning. The positioning of AAK hydraulic valves is to benchmark the global first-line hydraulic valve brands. In recent years, AAK has never wanted to recruit new engineers, because it is very difficult to change an engineer's cognition, which takes 18 months, and it will take another 18 months for him to do it, totally 3 years, but maybe he left in the second year, and he had to say something he thought he was right. The manufacturing of hydraulic valves is exquisite. This characteristic is in the upstream of the manufacturing industry - materials, key parts, manufacturing equipment, etc. need long-term investment, continuous tracking and the awareness of excellence, which is also the embodiment of the "craftsman spirit". No matter how iterative the technical cycle of the hydraulic valve is, your skills must not age, the craftsman spirit must not be lost, and the masterly skill must be really masterly. The road of quality is just like practice Buddhism or Taoism. The practice of good people has to go through thousands of risks and obstacles, same as the difficulty of eighty adventurous experiences before Tang Sanzang finally got the real Buddhist scripture. In the first few years of AAK hydraulic valves, we had to take a detour. There are a lot of south walls to hit, pits to fall and tuition fees to pay. Maybe this is the growth of AAK. Growth is as painful as death, and the essence is also the same as death. It means the disappearance of old quality standards and the birth of new quality standards. Accept it, face it. Then, we can constantly upgrade and grow into what we expect.
