AAK Hydraulic Cartridge Valves Supplied to 7 world top 500 enterprises

Today, the American customer April has placed another new order for hydraulic cartridge valves. Coincidentally, this PO is for 100 non-standard customized hydraulic cartridge valves that AAK has cooperated with them for 10 years. April is the first customer of AAK Hydraulic Valve to enter the overseas market, and also the first foreign trade order of AAK Hydraulic Valve 3 years after its establishment. Up to now, AAK hydraulic cartridge valves have been supplied to 7 world top 500 enterprises. AAK hydraulic cartridge valves adhere to 3 points, adhere to the manufacturing quality of hydraulic cartridge valves, pay attention to research and development, and focus on innovation. In particular, the high-precision and high-performance hydraulic cartridge valve samples have been defeated repeatedly, but we never give up until success. April's first inquiry is for hydraulic cartridge valves used in the military industry, with an accuracy of 0.8μm or less, the durability of more than 1 million times, and the opening and closing performance of 1 second. Our engineer was a little timid when he saw these requirements. I told him that if the development was successful, all the credit would go to him. If it failed, I would pay for it. 2 months later, the samples of AAK hydraulic cartridge valve was sent out. 2 weeks later, April reported that the opening and closing performance of AAK hydraulic cartridge valves reached the standard, but the accuracy and durability tests failed. This indicates that the material selection is incorrect and the process is correct. I told April that AAK was confident that the samples would be successful. 3 months later, the test of AAK hydraulic cartridge valves still failed, and the durability was barely 800,000 times. I encouraged the engineer to continue the test. 5 months later, the AAK hydraulic cartridge valve was approved by April. At the same time, the never say die spirit of AAK also makes April admire, because AAK is the only manufacturer of hydraulic cartridge valves that insists on testing samples in 1 year and does not give up. AAK hydraulic cartridge valves, in the face of failure, the wealth gained is that after every failure, there is an increase in technology accumulation, of which the most critical is 3 points: 1. Equipment updating is not stopped, and fixture innovation should be synchronized. 5 years ago, the precision honing machine imported from the United States was introduced. The accuracy of valve holes processed by other hydraulic cartridge valve manufacturers is 0.8μm--1.0μm, while with AAK synchronous innovation fixture, the valve hole accuracy can be within 0.6μm- -0.8μm, which is 20% higher. 2. Material types: AAK material warehouse has 12 kinds of special steels, such as 3Cr3Mo3W2V hot work die steel, 20CrNi2MoV high-permeability carbon bearing steel imported from Germany, Hastelloy alloy steel imported from the United States etc. At the same time, there are 8 kinds of sealing ring materials. At any time, we can meet the requirements of customers with high quality hydraulic cartridge valves. 3. Technology and process upgrading: AAK has senior engineer from HAWE, and technical teams with an average of more than 15 years of industry experience, adhere to the manufacturing quality of hydraulic cartridge valves, pay attention to research and development, and focus on innovation. AAK hydraulic cartridge valves are supplied to 7 world top 500 enterprises. You can also try a small order! https://www.aakindustry.com/info-det , ail/hydraulic-cartridge-valves-aak320

AAK Hydraulic Relief Valves Opening and Closing in 1 second

Romero from Spain has cooperated with AAK on a hydraulic pressure control valve for 3 years, and it is re-ordered 3 times a year. He has been very smooth on every purchase, but in October last year, he encountered problem on a batch of hydraulic relief valves purchased from other hydraulic valve manufacturer, and was complained by customers one after another, which made the boss very disappointed with him. AAK finished the non-standard customized hydraulic relief valves with 1 second opening and closing performance within 30 days, which made Romero win back the trust of the boss. Not long after returning from the Spring Festival holiday this year, Romero emailed to ask whether 50 hydraulic relief valves with opening and closing ability of less than 1 second can be customized within 30 days, and stressed that the flow must be stable. Because the new year just started, there were many things in the workshop, and I wanted to refuse. After several rounds of email communication, I learned about his predicament. In the second half of last year, their company produced a batch of hydraulic power units for ship equipment. 3 months after sales, the customer complained that the pressure supply of the system was unstable. It was found that the opening and closing performance of the hydraulic relief valve was poor and the flow control was unstable, which led to the unstable pressure supply of the system. The original manufacturer of the hydraulic relief valves said that this is an individual phenomenon, and the hydraulic relief valves with problem can be replaced for free. But unexpectedly, in the next month, they received complaints from customers one after another, and can not get into contact with the original manufacturer, making their after-sales service hard to cope with. The boss was very angry and requested Romero to re-customize 50 hydraulic relief valves within 40 days, and the manufacturing quality must be excellent. Romero contacted several hydraulic relief valve manufacturers. They either can't make hydraulic relief valves with opening and closing performance less than 1 second, or they need 60 days to customize 50 hydraulic relief valves. A week has passed without any progress. Romero is extremely worried. In the past 3 years, I have enjoyed working with Romero. After discussing with the engineer, I decided to help him. After 30 days, AAK sent 50 hydraulic relief valves with opening and closing ability less than 1 second. Today, Romero informed that with the use of AAK hydraulic relief valves, their equipment has not been complained in nearly 6 months. Before installation, their engineers specially tested the opening and closing performance of AAK hydraulic relief valves, each within 1 second. I told Romero that our guarantee is not 6 months, but 12 months is our pass line. As long as there are no deliberate human problems, the service life of AAK hydraulic relief valve is 2 million times, which is benchmarked with the quality of HydraForce. This is also the reason why many hydraulic valve manufacturers can not do it. AAK has already surpassed its domestic counterparts. 1. The selection of the pressure spring of this hydraulic relief valve is the key. 60Si2CrVA alloy steel pressure spring is its perfect match. The tensile strength and yield strength of the pressure spring is at least 70% higher, ensuring the opening and closing performance within 1 second. 2. AAK uses the high-precision honing machine imported from Switzerland to finish this hydraulic relief valve, and the valve hole accuracy can be within 1.0μm, the flow stability is guaranteed, while most of the hydraulic relief valve manufacturers are around 2μm. 3. AAK hydraulic valve has a large amount of data storage. With the most advanced UG/SOLIDWORK software and finite element analysis method, the process data can be configured in 2 hours, which is 3-6 times faster than other hydraulic valve manufacturers. AAK hydraulic relief valves, opening and closing in 1 second, durable for 2 million times, you can also have a small try! https://www.aakindustry.com/info-detai , l/hydraulic-relief-valves-aak319

Adhere to 3 working habits for 24 years, the growth of AAK Hydraulic Valves

In the workplace, 90% of people leave the computer, and their brain is blank. This is very fatal and it is difficult to grow into a person who is in charge. In AAK Hydraulic Valve, if colleagues are in such a state, they need to be criticized. Some people are very curious about how my brain can hold so many things.   I have been working for 24 years, and 3 working habits have always been with me. As long as you persist in doing so, your brain can also search or screen at will like a computer. Whether you are an industrial product manufacturer such as hydraulic valves or a non manufacturing enterprise, it can be used. The first habit is punctuality, and we should respect time. I don't like waiting for others, so I made up my mind not to let others wait for me. Even if there is an emergency, don't let people wait too long. For example, when I make an appointment to meet at 8:00, my instruction to the brain is to meet at 7:50. I don't like to be late. When I first joined the work, the company stipulated that I should go to work at 8:30. At this time, there are a circle of people around the punch card. Some of them are still sweating. I don't understand. I set myself a working time of 8:10, which means I have 20 minutes of leisure. I spent 15 minutes to review yesterday's events and 5 minutes to sort today's events. I have a regular schedule every day, such as what time to get up in the morning and what to do at what time to avoid the first thing delaying the second thing and the second thing delaying the third thing. The second habit is taking notes. I will write down what I learned today and what I gained.   A bad pen is better than a good memory. You can't remember it with your brain alone. People remember more than you do. That's because they use more pens than you do. For example, when we do hydraulic valve design or programming, we often need to learn some tools or methods, relevant books or documents, which are unified in a fixed folder, and summarize the basic points of the tools or methods. For example, I need to file on the same day how to solve the difficult problems of the hydraulic valves raised by the customers or the hidden quality problems of the hydraulic valves in the workshop. Otherwise, I will basically forget about them next time.   I insist on taking notes. There are already 6 thick books. I write on them what problems I have encountered one day, one month, one year, how I did the first step, the second step and the third step, and my experience. In my spare time, I'll look through it. Some can be extended. The third habit is to make a weekly list. If necessary, the four quadrant rule of time management shall be followed.   Every Monday morning, I arrive at the company half an hour earlier than usual. I will write down what I want to do this week, make a list and make a priority. At the same time, I will also make a summary of the previous week to see what progress was not completed and analyze the reasons.   Those engaged in the production of hydraulic valves should not grasp everything at once. When arranging things, they must give priority. If there are 7 things to be done in a week, but only 4 things have been completed in the end, but if these 4 things are the most important things, it may be OK. If only 4 pieces are completed randomly, the effect is very general. How to focus on the most important things is also a required course.   Good habits, good behavior, good results. In particular, AAK hydraulic valves are faced with customers who pay attention to quality and cannot be careless. https://www.aakindustry.com/info- , detail/hydraulic-valves-aak318

AAK hydraulic relief valves with large flow was intact after 1 year

Patrick is from a Dutch hydraulic equipment manufacturing company. Since the beginning of last year, the order of a high-precision and large flow hydraulic relief valve has been tossed for more than half a year, and finally he had to return to AAK to place the order. At the beginning of last year, Patrick sent an inquiry for 30 hydraulic relief valves. 3 days after AAK's quotation, Patrick placed the sample order, but there was no reply after the hydraulic relief valve samples were sent. It was not until the beginning of last month, that is, more than half a year later, Patrick sent an e-mail asking whether each hydraulic relief valve in the regular order could guarantee the same quality as the sample? I felt something was wrong. After several rounds of e-mail communication, I learned that Patrick gave the regular order to another hydraulic relief valve manufacturer, and the price was more than 15% cheaper than AAK. However, after 8 months, the main valve spools of some hydraulic relief valves were worn, resulting in loose fitting of valve body holes and even grooves, resulting in failure to raise the pressure of the equipment system. According to the feedback of the original hydraulic valve manufacturer, this hydraulic relief valve has large flow, high frequency of use, high accuracy of valve hole, and wear is normal. 2 months later, more and more complaints were received, but the original manufacturer surrendered and asked Patrick to source other hydraulic relief valve manufacturers. Patrick was a little scared and had to go back to AAK. Because the AAK hydraulic relief valves used in the original design equipment has not been abnormal for more than 1 year, it would be better to choose AAK even if the price is more expensive for 15%. If the hydraulic relief valves with large flow need to have high accuracy and be durable for more than 1 year, or more than 2 million times, the material selection, processing and quality awareness are indispensable. For the hydraulic valve manufacturers who can guarantee these 3 points at the same time, you may not find a third one in Ningbo. 1.AAK has American high-precision CNC honing machine tools. The surface roughness after honing is less than Ra0.8 and the cylindricity can reach 0.5μm. Axis straightness can reach 1μm. It is especially suitable for finishing the valve hole of large flow hydraulic relief valves. The processing aperture range is 5-500mm, and the depth diameter ratio can reach 10. For large flow hydraulic relief valves with large aperture, most hydraulic valve manufacturers can only reach 2-3μm. 2.According to the large flow rate of this model, after 2 weeks of comparative testing, AAK has determined the German 20CrNi2MoV high-carbon bearing steel as the main material of the valve body. Its high wear resistance and contact fatigue resistance are 3 times that of other conventional steels, ensuring that there is no wear for more than 1 year. Most hydraulic valve manufacturers choose 12L14 free cutting steel. 3.AAK hydraulic valve has been supplied to 7 of the world's top 500 enterprises, and its quality awareness has been benchmarked with the international first-line hydraulic valve brands. AAK hydraulic relief valves, high precision, durable for more than 1 year, you can also try a small order! https://www.aakindustry.com/info-det , ail/hydraulic-relief-valves-aak317

Chinese Hydraulic Manifold Manufacturer 2 Expenses on 3 Giants

Finding your life mentor will benefit you for a lifetime, whether you are a Chinese hydraulic manifold manufacturer or an individual. There are 3 types of people, and AAK, a Chinese hydraulic manifold manufacturer, suggests that you look for them. They may be your mentor.   Firstly, no matter which industry you work in, you must find the leader of this industry, find a way to chat with him, and become his friend is the best. It will take you to see the highest point of this industry. For example, Chinese hydraulic manifold manufacturer AAK found SUN Hydraulics and HydraForce in the early production of hydraulic cartridge valves. In the production of hydraulic manifolds, we found Honeywell.   Secondly, become good friends with a person with difference in age, someone in their teens or twenties older than you. Because he has had many falls in his life, he will teach you, provided that he is a successful person. Failure has never been the mother of success, only success is the father of success. For example, Chinese hydraulic manifold manufacturer AAK has our chief engineer who has worked in several major companies in the hydraulic industry, and successful cases are engraved in his mind. Thirdly, you can find people who are cross industry and have a good understanding of various industries, such as investment tycoons, journalists, consultants, trade experts, etc. These people may know the pitfalls of multiple industries, and you can cross border to learn about some things that will inspire you. For example, Chinese hydraulic manifold manufacturer AAK is not good at following other Chinese hydraulic manifold manufacturers and using traffic advertising to solve the sales of hydraulic manifolds, that is, "buy it, buy it, buy it at a lower price"; but Chinese hydraulic manifold manufacturer AAK is more willing to do technical output, using expert image and trust to solve the sales of hydraulic manifolds, that is, "love it, love it, why love it". Most Chinese hydraulic manifold manufacturers may not be different in the visible physical part, but the functions of hydraulic manifolds, especially in terms of quality stability, vary greatly and have a large gap.   Whether you are a Chinese hydraulic manifold manufacturer or an individual, it takes a lot of time and even a lot of money to be with these industry leaders. If you fall, take a look at how much money you'll have to spend. How can we approach these big shots? There are 2 methods. Firstly, spend money. Secondly, take time.   Chinese hydraulic manifold manufacturer AAK, insists on using 2 expenses to follow the 3 giants.

AAK Hydraulic Cartridge Needle Valve 2 Features

Melanton is from Mexico, and has cooperated with AAK for 3 years. Some time ago, the commissioning of their new paper cutter was not smooth, because of the hydraulic cartridge needle valve in the hydraulic system. After communication, it was learned that in order to catch the time, this hydraulic cartridge needle valve is customized by a local hydraulic cartridge needle valve manufacturer who has cooperated with them for 5 years in Mexico. When the liquid in the hydraulic system flows in reverse direction, the reverse flow resistance is large, resulting in slow operation of the equipment. After the original manufacturer of the hydraulic cartridge needle valve improved twice, it still failed. According to the hydraulic schematic diagram, the drawing of hydraulic cartridge needle valve, and paper cutter equipment working video, I told him that the reverse flow resistance of the hydraulic system increased, probably due to the limited opening or not opening of the oil port, and the hidden danger of flow. On the third day, he sent me 3 samples of the original hydraulic cartridge valve manufacturer, and asked me to improve based on the original samples. After 45 days, AAK sent 15 samples of hydraulic cartridge needle valves. 3 weeks later, Melanton informed us by email that the paper cutter equipped with AAK hydraulic cartridge needle valve was fast and stable. AAK hydraulic cartridge needle valve can effectively reduce the resistance of liquid reverse flow, the key is due to the 3 unique structures: 1. The side wall of the hydraulic cartridge needle valve body is provided with an oil inlet and an oil outlet which are connected with the inner chamber. The compression spring in the inner chamber is installed on the valve spool, and the head of the valve spool is in the shape of a conical table. One end of the compression spring is connected to the head of the valve spool, and the other end is connected to the plug at the end of the inner cavity. 2. The head of the valve spool is blocked between the oil inlet and the oil outlet. There is a valve rod near the oil inlet. The end of the valve rod extends into the inner cavity of the valve body and is connected to the head of the valve element. The outer end of the valve rod is connected with a hand knob. Turning the hand knob can adjust the relative position of the valve spool and the valve body, and can change the flow. 3. The contact surface between plug and valve spool is provided with a circular groove, and the valve spool can be buttressed in the groove. When the oil flows in reverse direction, the valve oil port automatically opens to reduce the liquid resistance. The optimized AAK hydraulic cartridge needle valve, when the oil flows in reverse direction, the valve spool will open the oil port under the action of the compression spring, and the reverse direction will be immediately opened to make the liquid flow back, not only the liquid flow resistance is small, but also the flow is stable. It ensures that the paper cutter runs fast and stably. AAK hydraulic cartridge needle valve has small hydraulic flow resistance and stable flow. You can also try it! https://www.aakindustry.com/info-detail , /cartridge-needle-valves-aak495

AAK Hydraulic Valve Never Use Promotional Letter, Stick to 5A for Marketing

Last weekend, my friend, a colleague of hydraulic valves asked for advice on the promotional letter template. He also wanted to expand the international market of hydraulic valves. He knew that AAK hydraulic cartridge valves had been exported for more than 10 years and had many customers, so he subconsciously thought that the promotional letter of AAK hydraulic valves should be good and wanted to learn from it. I told him that AAK hydraulic valve has no fixed promotional letter template, and rarely sends promotional letters to customers. This guy mistakenly thought that I was unwilling to send them the promotional letter. Frankly speaking, 10 years ago, perhaps a good promotional letter might have made customers reply to you. Now, it's hard. For foreign trade promotion, I think the most unpromising thing is to send promotional letters. Why? 1) Take the initiative to do door-to-door selling, what do customers think of you and what do you think? 2) Without a little trust foundation, what you say is floating clouds in the eyes of customers. 3) Sending promotional emails without permission is like sending leaflets when meeting people on the road. I heard the "news" of a foreign trade enterprise before, which is actually old news. A team of dozens of people used promotional letters to find customers. As a result, the email server was judged to be a spam server, resulting in that the mailbox could only receive emails, but can not send emails. Surprisingly, it has been more than once. Why not change the practice of sending promotional letters? Because the thinking is solidified, always think that the old method is better. In the past, they must have achieved great success in promotional letters, so they stuck to it. I think this is also the reason why my friend asked me for the promotional letter template of hydraulic valve development. My thinking is, why do I have to go to customers and not let them come to me on their own initiative? Why can't the role be reversed? My philosophy: no business without trust, no price without value. Now many European and American customers work 3 days a week + 2 days at home, thanks to Online. AAK hydraulic valve adheres to the self media content marketing. AAK hydraulic valve content is displayed on its official website, more than 50 B2B platforms, Google's homepage, mainstream social media etc. At present, there are more tools and means, and a large enough stage matrix has been formed. These stages are where we, hydraulic cartridge valve manufacturers or other manufacturers, can perform and show. Of course, this job is really not easy, and it is impossible for a salesperson who does not understand 5 things (raw materials, process, technology, equipment, and quality control). This era not only requires you to know 5 things, but also requires you to be proficient. Where is the key? 1) Content, content, content. AAK hydraulic valve insists on writing what customers want to see. 2) Your content reaches customers, and your content affects customers. 3) Trust, trust, trust, only trust you, customers will be willing. Don't think about IP and brand. Trust is the most reliable. Conversely, without trust, how could it be called IP and brand? What is the essence behind IP and brand? Trust! Marketing actively, waiting customers passively. You have an epiphany. So it is. Most of the time, your epiphany is just the basic skill of others. In the past, the core of sales was that I was proactive enough to find you everywhere. After I found you, I pursued you and insisted on pursuing you. The logic of AAK hydraulic valve practice is 5A, that is, 5 steps: Aware, Appeal, Ask, Act, Advocate. The goal of AAK is to achieve mental availability and physical availability. To put it more generally, you can think of AAK hydraulic valves, and can buy AAK hydraulic valves. To explain 5A with an example, everyone knows that there are different kinds of laundry detergent in the market, and there are many people selling laundry detergent live now. If you are in the broadcasting room, you encounter a special detergent. Oh, there is also this kind of laundry detergent, which is the first step of Aware. You take some time to find out that this detergent looks good and attracts you. This is the second step of the Appeal. One day, your family needed laundry detergent. When you think about it, you went to search for the special laundry detergent you saw last time. This is the third step, Ask. After communication, you felt that the service was also good, so you placed an order. This is the Act in step 4. After using it for a period of time, the effect of laundry detergent is really good. You has changed from a user to a loyal user and even recommended it to your friends. This is Advocate in step 5. Of course, it is not easy to insist on doing 5A. Many times, you think you have worked hard, but it has no effect. The limit you think is just the starting point of others. AAK hydraulic valve, stick to the difficult road, no matter how far, it will eventually arrive. https://www.aakindustry.com/info-de , tail/cartridge-valve-manufacturers-aak423

AAK Hydraulic Valve Manufacturer 4 Understandings about Reliability

Last Friday, Tim from Mexico needed me to help him find a manufacturer of modular hydraulic valves in Ningbo China. Tim has been purchasing hydraulic cartridge valves from AAK for 5 years, and he knows that I did not intend to supply modular hydraulic valves that AAK cannot produce. I asked Tim about his requests or standards about modular hydraulic valves. His answer is in one word: reliable.   A reliable hydraulic cartridge valve manufacturer should have several levels of expertise. Firstly, what is reliability? What I understand as reliable is a verb, not an adjective, that needs to be done, not said. Everything has an explanation, everything has a place, and everything has an echo. Continuously delivering certainty to customers. About reliable, AAK has 4 levels of understanding: receiving and achieving, speaking and achieving, thinking and achieving, and knowing and achieving.   On the weekend, you go for afternoon tea with a friend, and the friend asks, "Do you think you are a reliable person? You may blurt it out immediately, of course I am reliable! But are you really sure? The vast majority of people instinctively feel that they are reliable, and few say they are not reliable.   For example, if you are the business leader of a hydraulic cartridge valve manufacturer, during the development cycle of a hydraulic cartridge valve, the customer suddenly has new requirements. Based on your professional experience and current process configuration, you believe that the customer did not consider it carefully and hastily executed it, which has more harm than benefit. May I ask, what will be your first reaction state and next actions? Do what the customer requested you to do, or give customer advice? Do you think this is reliable? The answer is, not necessarily. This doesn't work, that doesn't work, so what is reliability? A and B fight, the answer is hidden in C. Learn to creatively propose win-win solutions. How can we not only meet customer expectations, but also reduce the risk points in our heart as the hydraulic cartridge valve manufacturer? I firmly believe that as long as our thoughts do not slide, there are always more solutions than difficulties. This is reliable. This is the first level of reliability: receiving and achieving. Those who achieve this level will be more likely to be trusted by customers.   Whether a person is humble and reliable depends on their wording. For example, like to say 'whole'. What are you responsible for? “I am responsible for the entire hydraulic cartridge valve manufacturer's technology”, but actually just responsible for drawing drawings. For example, like to greatly round. For example, consider the future as the present. For example, completely disregarding one's promises. A person who speaks big, empty, or lies often speaks very well, but doing things poorly, this is unreliable. Reliable people never make promises easily. Although they can score 8 or 9 points, but always leave room for 5 or 6 scores. This is the 2nd level of reliability: achieving what is said.   Being able to think of what others think of is actually due to strong perception and high emotional intelligence. Many times, before your superiors speak, your colleagues can immediately feel what they are about to say. Being able to think of unexpected things is actually the meaning of responsibility. Responsibility is not responsible for what comes to mind. Responsibility is being responsible for those 'unexpected things'. A reliable person's thinking is like a fishing net, picking up important things and projecting their attention onto them. Concentrate efforts and do everything possible to ensure completion. This is the 3rd level of reliability: thinking and achieving.   Do what I know, and persist in what I firmly believe. For example, knowing the wrong material selection will affect the service life of hydraulic cartridge valves, knowing that the equipment is not precise will affect the accuracy of hydraulic cartridge valves, knowing that the machining accuracy is not in place will affect the functionality of hydraulic cartridge valves. Some hydraulic cartridge manufacturers know everything but cannot change anything. This is not reliable either. Knowing should be turn into action. This is the 4th level of reliability: knowing and achieving.   In business, reliability is a more valuable quality than intelligence. When a person is reliable, which actually means stability, makes others feel at ease for what they do. The orders for hydraulic cartridge valves handed over to you can be completed on time, in quantity, and as expected. There were no accidents, let alone scares. Reliable people are always the same, while unreliable people each drop their own chains. Being reliable in any state is a requirement for those who are constantly improving. Making customers trust and companies reuse, the most basic quality is reliability. There are thousands of intelligent people, but few reliable ones. A reliable person can be seen by powerful people, opportunities and resources, and can make things develop in a direction that benefits them. Only reliable people can go further. AAK, hydraulic cartridge valve manufacturer in Ningbo China, reliable to be human, reliable to work, only delivering certainty.  AAK HYDRAULIC VALVES (578) 2023-05-07 https://www.aakindustry.com/info , -detail/hydraulic-cartridge-valve-manufacturer- aak578

AAK Hydraulic Pilot Operated Relief Valves Angle Error of 0.06°

Fischer comes from a Spanish hydraulic equipment manufacturing company and is an experienced purchaser. Unexpectedly, the hydraulic pilot operated relief valves purchased last year made him depressed for more than 1 month. In August last year, the sales of one of their hydraulic power units was not satisfactory, and there were several complaints about unstable supply and pressure. The problem is that the angle error of the inner cone of the hydraulic pilot operated relief valve is large. The original manufacturer of the hydraulic pilot operated relief valves advised that this is an individual problem. But after replacement with new one, there are more and more complaints. The boss was very angry and requested Fischer to purchase a new batch of hydraulic pilot operated relief valves for replacement within 45 days. Fischer contacted with many hydraulic cartridge valve manufacturers and required that the angle error range of the cone inside the sleeve of the hydraulic pilot operated relief valves must be 100% controlled within ± 0.08 °. However, 1 week has passed and no one of these hydraulic valve manufacturers is willing to accept the order. Fischer was depressed and worried. Introduced by his friend Trinidad, an old customer of AAK, Fischer sent me an e-mail. According to his drawings of hydraulic pilot operated relief valve, as long as the angle error of the conical surface in the valve sleeve is solved, the unstable pressure supply of the hydraulic power unit can be solved. 1 month later, AAK sent 100 hydraulic pilot operated relief valves. Last week, Fischer informed by email that since AAK hydraulic pilot operated relief valves were used, there was no complaint about unstable pressure supply. Their engineers specially tested the internal cone angle of the hydraulic relief valves, which was 25% higher than their accuracy requirements and 100% controlled within 0.06°. Fischer was curious that the internal cone angle error of 0.06° could not be solved by many hydraulic valve manufacturers, but AAK exceeded the standard for 25%. As early as 3 years ago, AAK engineers innovated the precision machining of valve body. First, they established a manufacturing error model to control the error range of the angle of the inner cone below 0.06° and the maximum axial grinding tolerance of the corresponding sealing circle below 2μm. At the same time, a special detection device is innovated to improve the detection accuracy through error correction and ensure the stability of grinding manufacturing accuracy. The inner conical surface of the hydraulic pilot operated relief valve sleeve adopts the finishing process of carbonitriding and post grinding to accurately control the grinding amount. The key is to control the grinding amount. If the grinding amount of the inner cone surface is too large, it will result in the reduction of hardness, and the service life of the hydraulic pilot operated relief valve will be reduced, which leads to unstable pressure supply. AAK hydraulic pilot operated relief valves, strictly control the details, high accuracy, you can also try a small order! https://www.aakindustry.com/info-det , ail/hydraulic-pilot-operated-relief-valves- aak , 316

AAK Hydraulic Pilot Operated Relief Valves Withstand 500℃ High Temperature

Maverick is from a Canadian hydraulic equipment manufacturing company. In the first half of last year, the high-temperature hydraulic power unit dedicated to meltblown equipment sold by their company for less than 4 months was complained by customers. The engineer found that the opening pressure of the hydraulic pilot operated relief valves on the equipment deviated from the set standard pressure, resulting in unstable pressure supply. Through further inspection, it was found that the pressure spring in the valve failed. According to the feedback from the original manufacturer of the hydraulic relief valves, the fatigue resistance of the pressure spring is reduced due to the working condition environment exceeding 350℃ and long-term full load operation, so the pressure spring can only be replaced. 3 months later, the same problem occurred again. The customer complained directly to the boss. The boss asked maverick to source the hydraulic pilot operated relief valves with a service life of more than 1 year to replace the current stock. Maverick contacted more than 10 hydraulic relief valve manufacturers and they all said that the pressure spring life of the hydraulic pilot operated relief valves can only be guaranteed for 6 months under the high temperature of 350℃. The boss has pushed twice, but the new manufacturer of the hydraulic relief valves has not been found. Maverick is worried. Maverick found AAK Hydraulic Valves from Google and left us a message: how much temperature can the pressure spring of hydraulic relief valve withstand and ensure a life of 1 year? I answered directly: AAK used to ship hydraulic valves with high temperature resistance of 500℃, and no customer complained that the pressure spring was invalid. The next day, he provided the working condition requirements and production drawings of the hydraulic pilot operated relief valve, and informed that the current procurement of this hydraulic relief valve was not smooth, and urgent replenishment was needed to replace it. AAK engineer found that the hydraulic pilot operated relief valve not only has high requirements for the spring, but also has shortcomings in the design. We advised the design change suggestions and promised to complete the trial order within 45 days. After 45 days, AAK sent out 30 hydraulic pilot operated relief valves. Last week, Maverick sent an e-mail that it is going to be 1 year, the equipment installed with AAK hydraulic pilot operated relief valves has no abnormal pressure supply till now. He needs to re-order 300 more. Under high temperature conditions, the service life of AAK hydraulic pilot operated relief valve is more than 1 year, it is so different from the most of the peers are due to the following 3 points: 1.AAK engineers have more than 20 years of development and design experience. The dynamic balance of the valve spool of this hydraulic pilot operated relief valve is high. Only by optimizing the valve port size can the flow always be controlled within the set pressure range. On the contrary, it will affect the pressure supply. This skill is very particular. 2.AAK has unique method to choose pressure spring, chooses 30W4Cr2V heat- resistant pressure spring steel with the best opening ratio as the core component of this hydraulic pilot operated relief valve according to the pressure range and spring stiffness coefficient. The pressure spring will not fail even if the oil temperature is higher than 500℃. 3.AAK Hydraulic Valve has developed 500 non-standard customized hydraulic cartridge valves for 7 world top 500 enterprises. Maverick also privately informed that the performance of AAK hydraulic pilot operated relief valve was admired by their engineers and they introduced AAK to several peers. AAK hydraulic pilot operated relief valves, optimized design, strict material selection, you can also try a small order! https://www.aakindustry.com/info-det , ail/hydraulic-pilot-operated-relief-valves- aak , 315

AAK Hydraulic Cartridge Directional Control Valve Accuracy Control Skills

Renato comes from Brazil and recently developed a hydraulic cartridge directional control valve, which caused him trouble. In May this year, their improved hydraulic power unit required customized hydraulic cartridge directional control valves. Renato chose an old supplier to make samples. The samples were recognized by their technical department except for the valve hole accuracy of the hydraulic cartridge directional control valve. After sending samples several times, the original manufacturer still failed to achieve the stable accuracy, wasting more than 60 days and had to give up. The technical department complained that Renato did not choose high-quality hydraulic cartridge valve manufacturer for this directional control valve, which made Renato very worried. Renato left a message on AAK website: Can AAK finish 30 pcs of non-standard customized Hydraulic cartridge directional control valves in 30 days, with valve cage and hole accuracy within 2μm, cylindricity within 3μm and surface roughness within Ra0.2? Most hydraulic cartridge valve manufacturers will not give a reply for this small quantity of customization, either they don't like it or they can't handle it. After communication, we learned that the original manufacturer of the hydraulic cartridge directional control valve wasted too much time, making him very passive. I sent him some cases that AAK customized hydraulic cartridge directional control valves for customers in the past, involving detailed requirements such as accuracy, cylindricity, surface roughness, etc. Renato paid the development fee the next day, and 30 days later, AAK sent out 30 samples of hydraulic cartridge directional control valves. 2 weeks later, Renato informed us that their technical department had approved AAK hydraulic cartridge directional control valve samples, and his trouble was finally resolved. In fact, the accuracy of this hydraulic cartridge directional control valve is not too difficult. As long as the precision machining details are in place, the stability of accuracy should not be a problem. The original manufacturer's processing is not poor, and may not be thorough in the details. This hydraulic cartridge directional control valve hole is precision machined by AAK using an American vertical honing machine. The precision requirement is for military products, and AAK has also upgraded its pneumatic measuring instrument, from precision machining to measurement, in one step, without the need for replacement processes. The spindle speed of the honing machine is set between 220-250 rpm, and most hydraulic cartridge valve manufacturers prefer to choose between 260-300 rpm. However, for the stability of accuracy, AAK does not recommend this setting. After installing the hydraulic cartridge directional control valve into the fixture, it can achieve simultaneous precision machining of 8 models. The feed adopts stepless speed change, and the abrasive particles forcibly enter the machining valve hole to ensure that there are no dead corners in the valve hole. The valve cage bears constant grinding force, which is also conducive to the stability of accuracy. AAK hydraulic cartridge directional control valve, 1 equipment, 2 details, ensuring accuracy and stability, you can also give it a try!

AAK Hydraulic Pressure Reducing Valves Unique Design Skills

At the beginning of this year, Liam from the Netherlands found AAK Hydraulic Valves on Google. He told me that he encountered the dilemma of purchasing hydraulic pressure reducing valves. Their company has developed a hydraulic support column used in coal mining. The hydraulic pressure reducing valve used is critical to the stability of the equipment. Their engineer designed the hydraulic pressure reducing valve according to the system principle, and Liam found a 5 years experienced hydraulic pressure reducing valve supplier to test the sample. After 50 days, the equipment commissioning was not smooth, and after 1 hour of operation, the support was unstable and noisy. At first, it was thought that it was caused by the leakage of the hydraulic pressure reducing valves, but there was no abnormality after testing the hydraulic pressure reducing valves individually. Their engineer spent another 2 days checking each hydraulic element one by one, but could not find the root cause of the problem. The delivery time of the prototype was less than 2 months. The boss was worried and asked Liam to contact the manufacturer of the hydraulic pressure reducing valves to help analyze the cause. 1 week passed, Liam consulted more than 20 hydraulic cartridge valve manufacturers, but none of them gave a plan. Liam was helpless and had to continue to find new manufacturers of hydraulic pressure reducing valves. According to Liam, this is a systematic problem. Based on his hydraulic schematic diagram, video of abnormal hydraulic column test run, AAK technical team had discussion and judged that the problem was still on the hydraulic pressure reducing valves. Liam said that their engineer tested the hydraulic pressure reducing valves separately and found no abnormality. I suggested that only by redesigning the hydraulic pressure reducing valve can the potential safety hazards of the hydraulic column be solved. Perhaps Liam was half convinced, maybe there was no other choice, he paid the development cost of the hydraulic pressure reducing valves. After 45 days, AAK sent the 20 newly designed hydraulic pressure reducing valves. 2 weeks later, Liam informed that the equipment had been running for 1 week, without noise, and the support was rising steadily. It could be delivered to the customer immediately. Their engineer wanted to know how AAK designed it. AAK newly designed hydraulic pressure reducing valve has the characteristics of high nominal pressure, large flow, good opening and closing characteristics, stable performance, reliable sealing, small volume and compact structure. We design and produce from the following 3 points, which is unexpected to most of our peers. 1. From joint, valve spool, valve spool sleeve, ejector rod, spring, base, valve body, axial hole and radial hole, from material selection to processing, we have made separate plans. 2. The axial hole is connected with the lower chamber of the column. The joint of the hydraulic pressure reducing valve is provided with an unloading channel. The radial hole of the valve spool can be connected with the unloading channel. The valve spool is connected with the spring through the ejector rod, the other end of the spring is connected with the base, and the joint is fixedly connected with the valve body. 3. A sealing ring is arranged between the valve spool and the inner wall of the joint, and an O-ring is arranged between the ejector rod and the joint. A special O-ring axial seal spring balance structure is adopted. Liam privately told that his boss had increased his salary for 2 levels and listed AAK as the preferred supplier of hydraulic pressure reducing valves. AAK hydraulic pressure reducing valves, unique design skills, high manufacturing quality, you can also try a small order! https://www.aakindustry.com/info-det , ail/hydraulic-pressure-reducing-valves- aak314

AAK Hydraulic Relief Valves Deep Hole Processing Skills

The processing difficulty of hydraulic relief valves with deep hole is a pain point in the industry. The greater the length diameter ratio, the greater the difficulty. Pablo, an American Hydraulic customer, has recently been besieged by an order for hydraulic relief valves with a length diameter ratio of 11:1. The original hydraulic relief valve manufacturer confirmed that the processing quality could be guaranteed during the quotation. However, in the actual proofing, it could not overcome the difficulty of deep hole. 3 proofs and 3 failures wasted 8 weeks. However, his customer had been pushing for the samples, and Pablo was in a dilemma. Pablo had to find new hydraulic relief valve manufacturers. Within 2 days, he contacted nearly 30 hydraulic cartridge valve manufacturers. All of them said that they can only produce hydraulic relief valves with a length diameter ratio of 5:1. Pablo realized that trouble was coming and was worried. Pablo learned that his friend Caleb purchased high-precision hydraulic cartridge valves from AAK, so he contacted us. According to the e-mail instructions and drawings of hydraulic relief valve sent by Pablo, the parameter requirements are high, that is, the tensile strength of hydraulic relief valve is 300N/cm², the compressive strength is 540N/cm², the clearance between the valve hole and the valve body is between 0.005 and 0.015mm, and the valve hole diameter is between Φ10~Φ41mm, the length of the valve body is 70mm, the maximum length diameter ratio is 11:1, and the dimensional accuracy of the valve hole is H6 ~ H7. When I saw the requirements of this hydraulic relief valve, I knew that most hydraulic valve manufacturers could not process it. Even if it is processed, its accuracy is a hidden danger. After internal discussion of AAK technical team, I replied to Pablo that AAK could send samples of hydraulic relief valves in 3 weeks, and the parameters could meet the requirements of the drawings. I felt Pablo's skepticism. Maybe the original hydraulic relief valve manufacturer also said like this but did not do it. He repeatedly emphasized the processing of the length diameter ratio and the accuracy requirements. After 20 days, AAK sent 6 samples of hydraulic relief valves. Pablo approved AAK hydraulic relief valve samples on the 5th day after receiving the samples. At the same time, he is curious that the original manufacturer failed in making samples of this hydraulic relief valve with the length diameter ratio of 11:1 for 3 times, but AAK succeeded at one time. The reason why AAK can produce the hydraulic relief valves with a large length diameter ratio mainly due to the following 3 points: 1. The long drill bit of W12Cr4V4Mo high-performance high-speed steel is selected to replace the conventional carbon tool steel drill bit. The hardness and heat resistance of the drill bit are increased by more than 1 times, and the impact toughness is also increased by 2-3 times. 2.During deep hole machining, the chips are not easy to be discharged, easily blocked or even broken. After grinding, the AAK bit reduces the resistance, and then cooperates with the cutting fluid to drill, which completely solves the chip accumulation. 3. According to the length diameter ratio, reasonably select the drilling amount, which is a skill. AAK hydraulic relief valves, good at deep hole processing, no deformation, welcome to try! https://www.aakindustry.com/info-detai , l/hydraulic-relief-valves-aak313

AAK Hydraulic Cartridge Valve 3 Advantages

Dakshesh is from a hydraulic equipment manufacturing company in India. They have a batch of high-power hydraulic cylinders and need to customize hydraulic cartridge valves. Dakshesh chose a local manufacturer that has cooperated for 6 years to make samples. During the equipment commissioning, the hydraulic cartridge valve has large pressure impact, noise, and the overload overflow protection action is not sensitive, resulting in the instability of the hydraulic cylinder. The manufacturer of the hydraulic cartridge valve reported that these are unavoidable under the working condition of 450 bar high pressure. Dakshesh contacted more than 10 other hydraulic cartridge valve manufacturers, but there were no results. The engineer has urged several times, Dakshesh was in a hurry. Dakshesh wrote an email to AAK. He introduced himself that one of his hydraulic cylinder customers suggested him to contact AAK HYDRAULIC VALVE. After communication, it was learned that one of my old customers in India introduced AAK to him. Dakshesh encountered the problem of hydraulic thread cartridge under 450bar working condition. For the hydraulic cartridge valve, under 450 bar high pressure, free of impact and noise, and stable operation, it is a typical requirement of German HAWE cartridge valves. I told him that this can be solved completely by HAWE, or AAK. For cartridge valves in the high-pressure field, AAK benchmarks HAWE, because our engineers have worked in HAWE for more than 10 years, and have excellent skills in high-pressure. After 35 days, AAK sent 12 customized samples of hydraulic cartridge valves. Yesterday, Dakshesh sent an email, wishing the AAK cartridge valve a smooth start. At the same time, he told me that the hydraulic cylinder with AAK hydraulic cartridge valve is not only noiseless, but also stable. The high- power hydraulic cylinder prototype has been delivered to the customer, and he is confident to get a big order. AAK hydraulic cartridge valve has low impact, no noise and is stable under high pressure of 450bar. The key is due to 3 unique structures: 1. The outer cavity of the right end of the hydraulic cartridge valve guide valve seat is connected with personalized pressure regulating screw and lock nut. The outer side of the left end of the guide valve seat is connected with the oil replenishing valve sleeve. 2. The oil make-up valve sleeve is coaxial with the main valve spool and the main valve piston. The pressure regulating screw is connected with the guide valve spool, and the two ends of the guide valve spool are respectively located in the inner cavity of the guide valve seat and the oil make-up valve sleeve. 3. The left end of the guide valve seat and the right end of the main valve spool are connected with the first spring, and the first spring is connected with the outside of the seal body. Both the front end of the guide valve seat and the inside of the main valve piston are equipped with orifices. When high- pressure oil passes through, the impact is small and there is no noise. For the optimized AAK hydraulic cartridge valve, the oil inlet of the guide valve seat is located in the rear hole of the valve body and the oil makeup valve sleeve, which is equivalent to integrating the guide valve, main valve and oil makeup valve into the oil makeup valve. In this way, it has the dual functions of overflow and oil replenishment. High pressure resistance 450bar, small impact, noiseless and stable. AAK hydraulic cartridge valve has three advantages under high pressure of 450bar. You can also try it! https://www.aakindustry.com/info-detail , /hydraulic-cartridge-valve- manufacturers-aak49 , 4
