AAK hydraulic valve block uses aviation aluminum, William admired

William comes from a Canadian hydraulic equipment company and has purchased hydraulic valve blocks in Ningbo for several years. AAK also supplies several difficult hydraulic valve blocks to their company. Although the quantity is not big, AAK service makes William very satisfied. In the second half of last year, William emailed an inquiry for a big quantity of order for hydraulic valve blocks. William said that the quotation was 40% higher than that of other hydraulic valve block manufacturers. I'm not surprised at all that he advised that the price of AAK hydraulic valve block is 40% higher. According to the hydraulic valve block drawing provided by William, AAK engineers found that according to the working condition requirements of the hydraulic valve block and the minimum wall thickness between two adjacent parallel holes (including installation threaded holes) in the middle of the valve block designed on the hydraulic valve block drawing is less than 4mm, the 6061-T6 Aluminum material marked in the drawing is not suitable, because this wall thickness can not bear the pressure of 350bar at all. During the operation of the equipment, the hydraulic valve block is likely to be broken down because it cannot withstand high pressure, that is, the materials used for the hydraulic valve block must be changed, rather than blindly follow the original hydraulic valve block drawing. AAK uses 7075-T6 aviation aluminum, which is the root cause of 40% higher price. A week later, William replied that he also sent the inquiry to the old hydraulic valve block supplier and more than 10 other hydraulic valve block manufacturers, but none of them suggested change the aluminum materials. He wondered whether AAK deliberately changed the materials for more profits. This large order of hydraulic valve blocks had been placed with the original supplier. Then I replied with a few words: good luck. Two months later, William sent an email saying that he regretted that he had not followed AAK suggestion at the beginning. The hydraulic valve block sample from old supplier was debugged 3 days after the equipment was installed. The manufacturer of the hydraulic valve blocks said that the sample was completely in accordance with the drawing and the development cost could not be refunded. The equipment commissioning time was wasted. The boss was very unhappy and asked William to try AAK samples even if the price was 40% higher, and asked to send the hydraulic valve block samples as soon as possible. AAK uses 7075-T6 aviation aluminum to make samples by soonest. After 30 days, AAK sent 2 samples of hydraulic valve blocks. Last Monday, when I opened the mailbox, I saw the unread email of hydraulic valve blocks from William. I knew that AAK hydraulic valve blocks passed the test of equipment commissioning. After opening, as expected, he placed a large order of 800 hydraulic valve blocks at one time. He also felt sorry to mistake AAK professional suggestion for deception. The 6061-T6 material on his hydraulic valve block drawing is only suitable for hydraulic valve blocks with a pressure below 220bar and a wall thickness of more than 5mm. Compared with 6061-T6, 7075-T6 aviation aluminum material has high strength, high hardness, more precision, good toughness, can be pressed or impacted for a long time, is not easy to deform, and has excellent wear resistance and fatigue resistance. It is the aluminum alloy with the highest strength at present. AAK hydraulic valve block is highly professional and cost-effective. You can also have a small try! https://www.aakindustry.com/info-detai , l/hydraulic-valve-blocks-aak204

Hydraulic Manifold Manufacturer AAK 2 Aspects and 3 Focused Points

Yesterday, a loyal customer from Russia, Resa, visited hydraulic manifold manufacturer AAK. In the evening, we had dinner together at the hotel. Perhaps due to weekend reasons, the restaurant served slowly. My colleague urged the waiter twice and asked when the dishes would be served? But it has no effect. This can't be blamed on the waiter, it's because the words my colleague said to urge the dishes were ineffective and didn't hit the point. Because it's not related to the waiter if the dishes are not served, it's the responsibility of the kitchen staff. I told the waiter to pay the bill in 5 minutes and return the dishes that were not served. The waiter immediately went to the kitchen to take a walk, and the serving speed also increased. An interesting phenomenon will be found that communication is essentially about hoping for results, and what is said also needs to be related to the parties involved and who bears the main responsibility. In the business society, people talk to each other about 2 points, either trust or benefits. But trust building requires a process. Some time ago, a customer in Türkiye selected 4 hydraulic manifolds from the hydraulic manifold manufacturer AAK, asked the hydraulic manifold manufacturer AAK to send samples for free, and promised to have a large order in 2024. Everyone, do you believe it? If you want me to believe it, that's okay. You pay first and I'll ship you a trial order. If it is a customer trusted by hydraulic manifold manufacturer AAK, we can trust the commitment. Similarly, when customers encounter problems, hydraulic manifold manufacturers said to them, ”please believe that we can definitely help you solve the problem”. At this point, will the customer believe it? Sometimes, the straight-line distance is not the shortest. Achieving it overnight is difficult. Information transmission is actually a process of building trust, and in this process, hydraulic manifold manufacturers need to do 3 things well. The first is clarity. I said you will execute, but for the outcome, as long as one party is arguing and passing the buck, this matter is unclear. The second is who bears the main responsibility, rather than the problem of playing football with each other. The third is whether the content mentioned is related to the parties involved. As long as these 3 points are in place, trust between both parties will be established. The benefits mentioned above by hydraulic manifold manufacturer AAK is what benefits it can bring to customers. Hydraulic manifold manufacturer AAK focuses on 3 benefits, one of which is the stability of manufacturing quality that some hydraulic manifold manufacturers cannot provide. The second is the hidden benefits, such as the communication efficiency of hydraulic manifold manufacturer AAK and the understanding of customer service. The thirdly, there are additional benefits, such as the hydraulic manifold service life of hydraulic manifold manufacturer AAK being twice that of other manufacturers in China. Hydraulic manifold manufacturer AAK, only discusses 2 points in communication with the customers, and then divided them into 3 small points.

AAK hydraulic counterbalance valve has been used in Sandstorm for 12 months

Today's weather is fine and I'm in a good mood, too. It took us 6 months to finally send the samples of the hydraulic counterbalance valves used in the sandstorm to Leonard. Their company has operated hydraulic equipment in Italy for more than 30 years. Leonard has been successful in purchasing hydraulic valves. AAK is their old supplier of hydraulic valves, but he has not purchased hydraulic balance valves from AAK yet. In the past, I asked why there was no inquiry or sampling of hydraulic counterbalance valves. He advised that their hydraulic counterbalance valves were purchased from another supplier who had cooperated for many years. At the beginning of last year, Leonard sent an inquiry for the hydraulic counterbalance valves. At that time, I was a little surprised. I estimated that he had trouble purchasing hydraulic counterbalance valves from the original manufacturer. After communication, it was learned that their company had a batch of hydraulic equipment sold to the Middle East in previous years, and the hydraulic counterbalance valves used had to be replaced almost every 6 months. The customer was not very satisfied with this high-frequency after-sales service. The original manufacturer said that the hydraulic counterbalance valves used in other places do not need to be replaced for 1 or 2 years. There is often haze or sandstorm weather in the desert areas of the Middle East, and the solid particles will virtually cause corrosion to the exposed surface of the hydraulic counterbalance valves, resulting in a high replacement frequency of the hydraulic counterbalance valves, and there is no good way to solve it at present. Leonard contacted AAK to improve their after-sales service. Try AAK hydraulic counterbalance valves to see if they can be used for more than 6 months in a sandstorm environment. According to the hydraulic counterbalance valve drawings from Leonard, the parameter requirements are of medium grade. The core is to select the stainless steel with the best corrosion resistance as the external parts of the hydraulic counterbalance valves. I suggest Leonard ask his customer to send the particles in the worst weather to AAK, analyze the PH of the environment, and then increase the PH by 30% to test the service life of different steels. Three months later, Leonard asked about the progress of the hydraulic counterbalance valve samples and joked that if AAK development is successful this time, all their future hydraulic counterbalance valves will be purchased from AAK. Another three months later, a special steel produced by ArcelorMittal group from Luxembourg was successfully tested by AAK technical team. Using this special steel as the external part of the hydraulic counterbalance valves can ensure corrosion resistance for at least 1 year. It took us 6 months to finally send samples of the hydraulic counterbalance valves used in sandstorm to Leonard. We also told Leonard that the production cost of hydraulic counterbalance valves made of special materials has been increased by 40%. Leonard said that if AAK hydraulic counterbalance valves are durable for more than 1 year, even if it is 40% higher, it is cheaper than using the original manufacturer's hydraulic counterbalance valves that need after-sales service twice a year. Last week Leonard emailed that the customer reported that AAK hydraulic counterbalance valves had been used for 9 months and there was no corrosion trace on the surface. The headache corrosion problem should be solved. Leonard privately informed that AAK hydraulic counterbalance valves still have a three-month test period. If there is no customer repair report within 1 year, AAK will be their hydraulic counterbalance valve supplier in the future. I think this is the best return for AAK R & D ability. AAK hydraulic counterbalance valves, which can't be achieved by peers, you can also give it a try! https://www.aakindustry.com/info-detai , l/hydraulic-counterbalance-valves-aak203

AAK Hydraulic Cartridge Needle Valve of High Stability

Amistad is from a hydraulic equipment company in Spain. His purchase has been smooth in the past 3 years. Some time ago, their company developed an automatic hydraulic ladder truck, and the hydraulic cartridge needle valve used was from a local supplier who had cooperated with their company for 3 years. During the commissioning of the hydraulic ladder truck, a hidden danger was found: the ladder truck fell slightly after the operating lever was suspended. After troubleshooting, the root cause was locked in the hydraulic cartridge needle valve. After testing the hydraulic cartridge needle valve individually, there was no leakage and no abnormal function. The manufacturer of the hydraulic cartridge needle valve recommended that another hydraulic cartridge check valve be integrated to assist the hydraulic cartridge needle valve. However, this would change the original design of the manifold and increase the cost, and this solution was rejected by the boss. Amistad contacted more than 10 hydraulic cartridge needle valve manufacturers, but after a week, it didn't work out. Amistad was worried. Amistad found AAK while browsing Google and left a message: How to optimize the hydraulic cartridge needle valve for hydraulic equipment with abnormal lifting? I guessed that he was in trouble when purchasing hydraulic cartridge needle valves. After communication, I learned the above story. According to his hydraulic schematic diagram, production drawings of hydraulic cartridge needle valve, and equipment working video, I told him first that it was not advisable to add components to the hydraulic manifold, which showed that the ability to control the hydraulic cartridge needle valve was not enough. Among the 5 steps of Musk's work method by Tesla's boss, 2 of them mentioned to simplify or optimize the traditional processes or components. Amistad seemed very interested in my idea. He was willing to try it once and asked us to sample it. After 45 days, AAK sent 6 samples of the hydraulic cartridge needle valve. 3 weeks later, he told me that after AAK hydraulic cartridge needle valve was installed on the ladder truck, it really eliminated the risk of "slight falling". He asked me to provide the price of this hydraulic cartridge needle valve. Strangely, 6 months after the price was sent, there was no any news from Amistad. Last week, Amistad suddenly "showed up", and sent a PO for 360 hydraulic cartridge needle valves, without discussing the price. He specifically mentioned that the high stability of their ladder truck conquered their users, and the equipment reservation exceeded expectations. How does AAK optimize the hydraulic cartridge needle valve? In view of this hidden danger, we adopt the proportional screw type instead of the traditional sliding type, whose valve seat sealing performance is improved by at least 30%, and has good compression resistance. AAK hydraulic cartridge needle valve has 3 major functions (multistage flow, stable load and rapid check) and 2 major performances (stability and reliability). It only needs a joystick to achieve precise positioning, and the flow of the hydraulic cartridge needle valve is zero, so there will be no leakage. The ladder truck can be instantly fixed at the designated position without falling. Most of the hydraulic systems of ladder trucks not only have hydraulic cartridge needle valves, but also have hydraulic cartridge check valves, which is not only costly, but also has potential stability problems. I think that maybe this is the reason why the ladder trucks of Amistad’s Company are so popular. AAK hydraulic cartridge needle valve is stable and reliable. You can also have a small try! https://www.aakindustry.com/info-detai , l/hydraulic-cartridge-needle-valves- aak399

AAK hydraulic valves only appear in the time and space you urgently need

Yesterday, a person of the same export trade of hydraulic valves came to my office. He lamented that it was too difficult to do the export of hydraulic valves. I thought he met someone who blackmailed him. He said that the export of hydraulic valves is B2B business. Because the hydraulic valve industry is too professional, he can't contact the decision- makers. From the first hydraulic valve inquiry from buyer to the final shipment, the whole delivery time is long, and it's too difficult to complete an order. This seems to be a common problem of B2B business. I suggest him read the book "the life that has not been destroyed". There is a sentence in the book: the real great is life. After being destroyed so many times, it is the most meaningful to live and die, and to have a bright future. Every time we are confused, it is the hidden willows and bright flowers that life gives us. AAK hydraulic valves, every product is exported to overseas. Whether it is the test order of hydraulic valves delivered by express, the urgent air shipment of hydraulic valves or the big sea shipment of hydraulic valves, it is the result of customers' trust in AAK. The hydraulic valves have strong professionalism, long delivery time, high amount and complex decision-making process, which requires the direct decision-making of senior management and even the boss. It's really difficult to break through layers and open the door of a hydraulic valve order. AAK is not in a hurry to close the deal of hydraulic valves, but regards it as a process of slowly accumulating influence, which is suddenly enlightened. AAK hydraulic valves have invested a lot of money in equipment upgrading, a lot of people in technical iteration and a lot of time in output content. Our ultimate goal is only to influence. Moisten things silently. Day after day, insist on using high stability hydraulic valves, high-quality content and high return rate of reputation to open the door of decision-makers of large companies. AAK hydraulic valves, with tolerance, planted a seed called "AAK influence". Many times, slow down the heart but work diligently and silently, until one day, when you meet a stranger offline, after greeting, he said to you: I already know you. I've read your content. It's really good. At this time, you will succeed. AAK hydraulic valves are just going this way. AAK hydraulic valves only appear in the time and space you urgently need. https://www.aakindustry.com/info-detail/hy , draulic-valves-aak202

AAK Hydraulic Cartridge Valves 4 Processes to Remove Impurities

Kenneth is from Israel, and has been in the industry for not a long time. His first purchase of hydraulic screw-in cartridge valves, caused customer complaints due to impurities. AAK uses 4 processes to remove impurities in hydraulic screw-in cartridge valves, solving Kenneth's troubles. In February this year, Kenneth needed to purchase a hydraulic screw-in cartridge valve, for use in hydraulic unit equipment. He has very limited hydraulic cartridge valve manufacturers in hand, and a colleague introduced one to him. This hydraulic screw-in cartridge valve is a model equivalent to HydraForce RV10-16. Kenneth purchased 100 hydraulic screw-in cartridge valves. At the end of June, the customer complained that the hydraulic screw-in cartridge valve was not sensitive, and the root cause was that there were residual impurities in the valve, but the proportion was not high. The original cartridge valve manufacturer advised that these are hydraulic screw-in cartridge valves in stock, and there may be some residual impurities that cannot be 100% avoidable. The only solution is to replace them with new ones. But what the customer needs is a 100% impurity free hydraulic screw-in cartridge valve, and Kenneth can only contact other hydraulic screw-in cartridge valve manufacturers. After 1 week, there is no any result. Kenneth was very upset. Kenneth found AAK on Google, and left a message on AAK website: Can AAK hydraulic screw-in cartridge valve be impurity free? After communication, it was learned that he had been in the industry for less than 3 months and had encountered the problem of impurities in hydraulic screw-in cartridge valves. I told him that AAK receives such inquiries almost every week regarding similar issues. The key to remove residual impurities in hydraulic screw-in cartridge valves lies in 2 steps: one is the export of impurities during processing, and the other is the cleaning of components. The cleaning of AAK hydraulic screw-in cartridge valves adopts 4 processes. In terms of process settings and detail handling, it is different from most manufacturers. Meanwhile, I forwarded him the video of our cleaning processes. The next day, Kenneth sent us an order for 100 pcs of hydraulic screw-in cartridge valves AAK hydraulic screw-in cartridge valve is cleaned using a multifunctional automated ultrasonic cleaning equipment, which has 4 processes and does not require manual labor. 1. Soak the components in water-soluble industrial cleaning agent for 1 hour, with a cleaning agent concentration ratio of 80%. Most hydraulic cartridge valve manufacturers in China purchase it from the market directly, and the soaking time is less than 1 hour. 2. By using a transducer, the sound energy of the power ultrasonic frequency source is converted into mechanical vibration, and the ultrasonic wave is radiated into the cleaning solution in the tank through the cleaning tank wall. The ultrasonic radiation time shall not be less than 10 minutes, and the micro bubbles in the liquid in the tank shall vibrate for 15 minutes under the action of sound waves. Under dual action, there is no residue of impurities. 3. Rust prevention treatment, soak with rust inhibitor for at least 20 minutes to ensure that each component does not rust. 4. Drying process. After each cartridge valve element enters the drying tank, it will stand for more than half an hour to ensure that each element is dried. AAK hydraulic screw-in cartridge, 4 processes to remove impurities, you are welcome to try it out!

Price positioning of AAK Hydraulic Manifold is defined from 3 dimensions

There is no harm without comparison. We talked about the manufacturing quality definition of AAK from 3 aspects in last article. The manufacturing quality of AAK hydraulic manifold is very close to those of foreign big brands, and perhaps some functional innovation is a little slower. At this time, I was thinking that AAK hydraulic manifold quality benchmarking is the international first line brands. Can the price also benchmark? The hydraulic manifolds of the international first line are basically from large enterprises, with brands, market influence, reputation and popularity. AAK hydraulic manifolds belong to small and medium-sized enterprises. How should we position our price? With the integration of manufacturing, performance and function difference, it is natural that different hydraulic manifold manufacturers have different quality. If the hydraulic manifold is of good quality, performance and function. If the quality is comparable to the top brands, then the price is also synchronized? Definitely not, because we are not a brand. No brand, no visibility. I always believe that no matter what products, there is no reputation, no loyalty, only trust, only popularity. For example, AAK hydraulic manifold has a high reputation in the Google system, so there are more inquirers. AAK hydraulic manifolds, such a small and medium-sized enterprise, does not talk about brand, only about popularity. AAK hydraulic manifolds define prices from 3 dimensions: 1. Hydraulic manifold is positioned at 70% of the global first-line brand price. On this premise, the quality of hydraulic manifold has been compared to the world's leading brands. Set the price according to the range of about 70% of the price of these big brands, and insist on bringing benefits to customers: AAK quality benchmarking global first-line brands, but the price is more than 30% affordable. 2. Conventional hydraulic manifold is similar to standard parts. Its price is 20% more expensive than that of domestic peers, but its service life is twice that of peers. In terms of hydraulic manifold raw materials and semi-finished products, AAK does not use materials or components commonly used by peers, but increases the procurement cost by more than 10%. With the production process of customized parts, the service life of AAK hydraulic manifold is at least twice long that of peers. In my opinion, the purchase cost is increased by 10%, the sales price can be increased by 20%, but the service life is twice that of the peers. 3. For hydraulic manifolds with manufacturing quality, performance and function are only at the top level of in China, AAK distinguishes peers with functional innovation. The price of this kind of hydraulic manifolds is difficult to determine. If it is set low, the quality will deteriorate year by year in the price war; If it's set high, nobody wants it. The characteristics are not obvious, and the purchase reason is not attractive. The quality is medium to high, and the technical performance indicators are not superior. AAK's strategy is to use our brains to make some peripheral innovations, and show its advantages in the differentiation of hydraulic manifold functions, becomes the top 1% of domestic subdivided industries. In any case, AAK first adheres to the quality three-dimensional of hydraulic manifolds (hydraulic manifold manufacturing quality, hydraulic manifold parameter performance, and hydraulic manifold function innovation). Then consider the three tiered price of hydraulic manifolds (AAK hydraulic manifold is benchmarking the world's leading brands, the performance life of AAK hydraulic manifold is twice that of its peers, and the top 1% of AAK hydraulic integration's domestic industry segments) AAK hydraulic manifolds, 3 dimensions of quality, and 3 steps of price. https://www.aakindustry.com/info-detail/hy , draulic-manifolds-aak466

Hydraulic Valve Manufacturer Customers from 4 continents and 31 countries

Hydraulic cartridge valve manufacturers focus on the foreign trade field, which has an advantage over domestic hydraulic cartridge valve manufacturers that only focus on the domestic market. You can meet customers from different continents and countries. Due to regional differences, their treatment of hydraulic cartridge valve manufacturers also varies. Hydraulic cartridge valve manufacturer AAK in Ningbo China has been engaged in hydraulic cartridge valve foreign trade for 13 years and has encountered customers from 4 continents and 31 countries. Their style and focus have inspired AAK. Let me report to you on the first weekend of 2024. Hydraulic cartridge valve manufacturer AAK has customers in 5 countries in North America, mainly in 3 countries (the United States, Canada, Mexico). Customers of hydraulic cartridge valves in the United States are concerned about trust. They will not easily send inquiries to new hydraulic cartridge valve manufacturers. Only when they trust the hydraulic cartridge valve manufacturer can they send an inquiry form. They don't care much about the price of the trial order for the cartridge valves, so they usually directly request the hydraulic cartridge valve manufacturer to conduct a trial order. If the quality is recognized, then the bulk order will come. As long as the follow-up is reliable and there is little chance of moving orders. Canadian hydraulic cartridge valve customers are similar to American customers, but their response is slower. After some trial orders are sent out, you only receive feedback after 1 year later. Mexican customers of hydraulic cartridge valves prioritize price over quality, and the probability of moving orders away from the original hydraulic cartridge valve manufacturer is also high. Hydraulic cartridge valve manufacturer AAK has customers in 14 countries in Europe, mainly 6 countries (Germany, Britain, Russia, Türkiye, Italy, the Netherlands). German hydraulic cartridge valve customers prioritize quality and do not inquire frequently with hydraulic cartridge valve manufacturers, but their inquiries often mean actual orders. Once the hydraulic cartridge valve manufacturer receives a PO for a model, as long as there are no issues with the manufacturer, the customer will not move the order. Russian hydraulic cartridge valve customers have many inquiries, and they seem to like to compare prices. One inquiry needs to be sent to multiple hydraulic cartridge valve manufacturers, which means you spend a lot of time here, but the effect may be average. The customers of hydraulic cartridge valves in Türkiye are diversified in Europe. Some customers are super sensitive to the price. Even if the quotation is 2-5% higher, you will not get the order. Some are similar to Germany, focusing only on quality. Hydraulic cartridge valve manufacturer AAK has customers in 6 countries in Asia, mainly in 3 countries (India, Pakistan, Vietnam). The business with hydraulic cartridge valve customers in India is not easy. There are also many hydraulic cartridge valve manufacturers in India, and they only inquire about prices from Chinese hydraulic cartridge valve manufacturers for two reasons: their domestic technology cannot do it, and they want to get a lower price. The situation in Pakistan and Vietnam is similar. First, compare the price, then compare the quality, and there is also some cleverness. Hydraulic cartridge valve manufacturer AAK has customers in 6 countries in South America, mainly in 3 countries (Brazil, Chile, Peru). Overall, new customers from Brazil have the most inquiries, and it usually takes one month for feedback or no feedback to be received. If the hydraulic cartridge valve manufacturer can withstand the first batch order, then you truly stand firm in their supplier system. The customers in Chile and Peru are similar, with low inquiry frequency and limited quantity. The hit rate is not bad, and there is no need to worry about future orders. To sum up, the hydraulic cartridge valve manufacturer AAK has many inquiries from the United States, Canada, Russia, Türkiye, India and Brazil, but the highest hit rate is with the customers from the United States. The good profits are with those customers from Europe, except those from Russia and Türkiye. The one who values quality the most comes from Germany. But no matter where the customer comes from, I think the core lies in 2 points: first, whether the customer trusts the hydraulic cartridge valve manufacturer, and second, whether the manufacturing quality of the hydraulic cartridge valve manufacturer is stable. In 2024, hydraulic cartridge valve manufacturer AAK will continue to focus on foreign trade accomplishment (reliability and making impossible possible).

AAK Solenoid Proportional Valve Benchmarking HydraForce

This week, we launched a new model equivalent to HydraForce SP08-20 SOLENOID PROPORTIONAL VALVE, NORMALLY CLOSED. At the beginning, we were also hesitant to develop, because currently none of a domestic hydraulic cartridge valve manufacturer in China can benchmark the standard of HydraForce SP08-20, especially the internal accuracy of the magnetic guide sleeve inside the valve, which is not only a high-end device that can solve. I know that as long as I promise to develop SP08-20 for customer, it will be accompanied by late night lights. As long as one detail is not in place, the characteristic curve cannot 100% benchmark HydraForce. I told my engineer that when developing SP08-20, my mindset is: Don't ask about harvest, but ask about cultivation. Take the time to try, and leave the rest to luck. Fortunately, AAK spent 6 months, 3 times material changes, 4 times testing samples, and finally achieved the standard of HydraForce SP08-20 SOLENOID PROPORTIONAL VALVE successfully. The characteristic curve is 100% benchmarking HydraForce, and there is no second one in China now. This is God's favor for AAK. AAK E-SP08-20 SOLENOID PROPORTIONAL VALVE, 2 main features: 1. Low leakage, internal leakage 5 drops/minute. 2. Performance benchmarking HydraForce, Ningbo has no second manufacturer SPECIFICATIONS: Max. Operating Pressure: 207 bar (3000 psi) Flow: See PRESSURE DROP VS. FLOW graph Internal Leakage: 5 drops/min max. at 207 bar (3000 psi) Temperature: - 40 to 120 °C (with Standard Buna N seals) Cavity: VC08-2  AAK E-SP08-20 SOLENOID PROPORTIONAL VALVE, 2 customers have already placed orders, and 3 customers have issued trial orders. You can also try out a small order. https://www.aakindustry.com/info , -detail/proportional-valve-aak543

Hydraulic pressure reducing valve run normally after using AAK sealing ring

The XX hydraulic manufacturing company in Germany has been rooted in the hydraulic system equipment of the airport for many years. A batch of hydraulic pressure reducing valves purchased by the novice Carla at the beginning of the year were repeatedly complained by the airport, which brought a lot of losses to the company's after-sales service and alerted the boss. In the first half of last year, Carla’s company sold hydraulic power units to Malaysia, which is used to supply emergency fuel to aircraft at the airport. The equipment was reported for repair after running for about a month. The after-sales engineer handled it at Kuala Lumpur Airport and locked the abnormality of the hydraulic pressure reducing valves according to the fault code. Finally, it was found that the sealing ring of the hydraulic pressure reducing valves was corroded, affecting the operation of the equipment. The engineer asked Carla to mail the new sealing ring to the site within 2 weeks. The manufacturer of the original hydraulic pressure reducing valves learned that the sealing ring was seriously corroded and was willing to replace with fluororubber sealing rings, which have the best corrosion resistance, for free. The manufacturer also reminded Carla that when she placed the order, the medium used in the hydraulic pressure reducing valves was not specified, so the conventional nitrile rubber sealing rings were equipped. Considering that Carla is a novice, he is willing to offer replacements for free. Carla thought that the abnormal hydraulic pressure reducing valves were solved in this way. Unexpectedly, the same problem occurred only two months after the replacement. The customer was angry and said that if the second after-sales service still couldn't solved the problem at one time, all the equipment would be returned. Carla went to the original manufacturer of hydraulic pressure reducing valves again, and the manufacturer gave up, because the fluororubber seal ring was their best choice. Now Carla was worried and had to turn to her purchasing director for help. The director asked her to contact AAK hydraulic valves first. If AAK still cannot solve it, there will be no need to waste time on Chinese hydraulic pressure reducing valve manufacturers and can only purchase from Germany. After receiving the email, AAK replied that she should not worry. According to the drawing parameters of her hydraulic pressure reducing valve, it matches a hydraulic pressure reducing valve used in aircraft completely that AAK produced for a Russian customer reorder some time ago. We still have some quantity in stock, and can ensure that AAK hydraulic pressure reducing valves will not be reported for repair for at least one year. The next day, AAK sent 10 hydraulic pressure reducing valves to Kuala Lumpur Airport. Carla emailed us a few days ago that after using AAK hydraulic pressure reducing valves, the equipment has been running smoothly for 6 months, while the ones from the original manufacturer were reported for repair in 2 months. She was surprised by the sealing ring of AAK hydraulic pressure reducing valves. AAK can't be careless in details. Like the original manufacturer, not to check the use medium of the hydraulic pressure reducing valves, but ship order blindly, this is zero tolerance for AAK. The aircraft hydraulic system uses highly corrosive aviation blue oil. Even the fluororubber sealing ring considered as the best by most manufacturers is still not suitable for this medium. Three years ago, AAK tested for many times and found that EPDM seal ring is the most suitable for aviation blue oil medium. Its special molecular structure is highly chemically stable, especially the anti-aging property is several times that of fluorine rubber. This is also the reason why Russian customer has been reordering the hydraulic pressure reducing valves on aircraft from AAK. AAK hydraulic pressure reducing valves have tips on sealing rings, which can be used in the airport. Peers can't think of it. You are welcome to give it a try! https://www.aakindustry.com/info-detai , l/hydraulic-pressure-reducing-valves- aak201

AAK hydraulic relief valve with 5 steps sand cleaning method is not blocked

AAK unique 5 steps sand cleaning method replaces the traditional method commonly used by peers, and completely solves the problem of valve stuck or filter blockage of hydraulic relief valves caused by hidden danger in sand cleaning. The American customer placed an order for the hydraulic relief valves to AAK 3 days after the test run. Most of the bodies of the hydraulic relief valves are made of nodular iron, vermicular iron and gray iron and cast by sand turning with resin sand as the modeling medium. Therefore, there is sticky sand in the casting, which is easy to cause valve jamming and filter blockage. Most of the common sand cleaning methods of hydraulic relief valves in the same industry are shot blasting and electrochemical sand cleaning. These methods have limitations and are not conducive to the stability of hydraulic relief valves. Gabriel is a purchaser of a hydraulic company in the United States. In previous years, he purchased the hydraulic relief valves in the United States. Recently, there is an order for hydraulic relief valves. The production of the original domestic manufacturer is full schedule, while the other hydraulic relief valve manufacturers dislike the small quantity and are unwilling to accept the order. The company asked him to check with Chinese hydraulic relief valve manufacturers. Among several hydraulic relief valve manufacturers recommended by his colleagues, Gabriel chose 3 of them to send samples after a round of comparison. After 20 days, the samples of these 3 hydraulic relief valve manufacturers were generally stable and prone to valve jamming or filter blockage. The root cause was the incomplete sand cleaning process of the hydraulic relief valves. When browsing B2B websites, Gabriel saw that AAK website www.aakindustry.com introduced the 5 steps sand cleaning method of hydraulic relief valves. He left a message on our website: Can AAK make the hydraulic relief valves not stuck or the filter not blocked? We replied him directly: AAK hydraulic relief valves with 5 steps sand cleaning method have been recognized by German customers. You are welcome to try the order. Gabriel subconsciously approved AAK hydraulic relief valves but was still some concerned because of no cooperation before, so he asked for samples to test first. According to the draft of hydraulic relief valves sent by him, we sent samples in 2 weeks. Gabriel issued official PO on the 3rd day after receiving the hydraulic relief valve samples for commissioning, and requested that the bulk goods to be 100% sand cleaned thoroughly. AAK adopts more efficient sand cleaning method and has its own unique 5 steps sand cleaning method for small and complex castings, 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, so as to peel the sand off the casting, and then the explosion of compressed air during ultrasonic cleaning is used to make the sand fall off, so as to achieve the purpose of 100% sand cleaning. Gabriel issued the PO in 3 days after receiving AAK hydraulic relief valves for testing. This is a witness of AAK unique sand cleaning methods. AAK hydraulic relief valves do not block the valve or filter, which is due to AAK unique 5 steps sand cleaning method. You can also have a small try. https://www.aakindustry.com/info-detai , l/hydraulic-relief-valves-aak200

AAK embedded the filter into the body of the hydraulic check valve

Nicholas is from an Italian hydraulic company. Last year, a batch of hydraulic equipment needed to use the hydraulic check valve urgently. Due to tight time, Nicholas purchased in Italy. After installing the local hydraulic check valve, the equipment commissioning was normal, but 3 months later, some users complained that the pressure of the power unit was insufficient. It was found that the hydraulic check valve was stuck on site, resulting in weak pressure supply of the system.    Nicholas contacted the original hydraulic check valve supplier and the supplier replied that the jamming was caused by unclean hydraulic oil. The on- site personnel found that the hydraulic oil was polluted, so they could only disassemble and clean the stuck hydraulic check valve. After replacing the hydraulic oil of the whole system, the equipment returned to normal. But a few months later, the same problem happened again, and Nicholas's after-sales personnel operated again as last time. The boss felt that the problem should be solved fundamentally after he knew it. Such after-sales cost is too high. Their engineers fed back that they could only install the filter screen at the inlet of the hydraulic check valve, but the original design of the equipment did not consider the position of the filter screen. It will cost more to refit the whole set of equipment.   The boss asked Nicholas to contact more local hydraulic check valve manufacturers to brainstorm. After knowing the problem with this hydraulic check valve from Nicholas, and the hydraulic oil is inevitably polluted, combining with their equipment working conditions and installation drawings, I told him that we can only find hydraulic check valve with filtering function. AAK has similar hydraulic check valve with automatic filtering function. Nicholas doesn't believe that AAK can provide such a hydraulic check valve. After receiving AAK sample and installing it, the equipment works normally. Nicholas asked us how long AAK hydraulic check valve with filter screen can work? We told him that there would be no users to apply for repair within 1 year.   Nicholas asked why we are so confident. I told him that a Canadian customer had the same problem last year. We developed this new hydraulic check valve. Within one year, Canadian customer has not reported that there is a problem with this hydraulic check valve yet. Half a year later, Nicholas sent an email saying that his customers had never changed the hydraulic oil after using AAK hydraulic check valves.   At that time, in order to save the installation space of filter plug-ins for the hydraulic system of Canadian customer, not to use bulky filter containers, and keep the system clean and extend the service life of hydraulic check valves, AAK designed a hydraulic check valve with filter embedded into the body, that is, the filter screen and the hydraulic check valve are installed in the valve block together. The filter made of 304 stainless steel can effectively remove the fine particles in the hydraulic oil, and it is no longer necessary to change the hydraulic oil once every 3 months.   AAK hydraulic check valve with filter screen saves money and worry. You can also have a small try! https://www.aakindustry.com/info-detai , l/hydraulic-check-valves-aak199

AAK Hydraulic Cartridge Directional Valve Spool Smoothness within Ra0.2

Derya is from Türkiye. Most of the customers in Türkiye who contact AAK are dealers of hydraulic cartridge valves, but Derya operates a hydraulic equipment manufacturing company. At the beginning of this year, they developed an aviation hydraulic power unit that requires high-precision hydraulic cartridge directional control valves, especially the surface finish of the valve spool to be controlled within Ra0.3. Derya customized the hydraulic cartridge directional control valve with a manufacturer in China that had been cooperating for 3 years. 2 months later, the debugging of the aviation hydraulic power unit was not smooth, due to the insensitive opening and closing performance of the hydraulic cartridge directional control valve and equipment operation hysteresis. The engineer found that the surface finish of the hydraulic cartridge directional control valve spool from the original manufacturer exceeded Ra0.5. The original hydraulic cartridge valve manufacturer stated that they can only produce more valve spools and select them one by one. Derya realized that the manufacturing quality of the original hydraulic cartridge valve manufacturer was unstable, so he had to choose a new manufacturer for the hydraulic cartridge directional control valve. However, 2 months had passed since then, Derya was in a hurry. Derya found AAK on Google and left a message: 1. How long does it take for AAK to customize the hydraulic cartridge directional control valve? 2. Is it possible for AAK to control the smoothness of the valve spool of each hydraulic cartridge directional control valve within Ra0.3? After communication, it was learned that he was facing the dilemma of customizing a hydraulic cartridge directional control valve. I provided him a customer case of a hydraulic cartridge directional control valve previously customized for a Russian customer, with a surface finish of Ra0.2 on the valve spool and a video of how we handled the surface finish of the valve spool. Derya had no concerns anymore and requested AAK to make samples. After 50 days, AAK sent 20 samples of hydraulic cartridge directional control valves. 4 weeks later, Derya informed us via email that their aviation hydraulic power unit had been successfully tested and was on its way to deliver to the customer. The smoothness of the AAK hydraulic cartridge directional control valve spool was controlled at Ra0.2 and satisfied their engineers. For AAK hydraulic cartridge directional control valve spool components, the first is to choose suitable materials. For this model, we use 20CrNi2MoV high permeability carbon bearing steel, which has wear-resistant performance and can better protect the smoothness of the valve spool. Then it is polished and precision processed, and AAK uses a Taiwan centerless grinder. The process setting for centerless grinding is done by AAK this way: Firstly, the surface error and feed speed of the grinding wheel are set, and the surface error value of the hydraulic cartridge directional control valve spool is set to within 2μm, the feed speed of the grinding wheel is set at 400mm/min. The relative vibration between the grinding wheel and the valve spool, as well as the contact stiffness between the valve spool, guide wheel components, and support plate, can be more smoothly controlled, ensuring that the surface finish of each hydraulic cartridge directional control valve spool can be controlled within Ra0.2 after processing. AAK hydraulic cartridge directional control valve, the spool smoothness controlled within Ra0.2, you can also give it a try!

AAK Hydraulic Cartridge Valve Spring Service Life Control

A few days ago, Titan, an old customer from Türkiye, sent me 6 samples of hydraulic cartridge valves. According to his description, there were 3 batches of the valves purchased from the original hydraulic cartridge valve manufacturer, and 2 batches of valves had abnormal service life. Some hydraulic cartridge valves had a service life of more than 1 million times, while some hydraulic cartridge valves had only about 700,000 times. However, no problem could be found in the selection of materials or accuracy of hydraulic cartridge valves. The original manufacturer of the hydraulic cartridge valves is also uncertain about the root cause of the problem, which has made Titan very upset. There are various possible reasons for unstable service life, such as material selection, machining accuracy, internal structure of the valve, and accessories. According to our testing, the valve provided by the original hydraulic cartridge valve manufacturer is unstable due to the quality of the spring, which affects the service life of the hydraulic cartridge valve. Titan mentioned that the Korean piano steel wire material used by the original hydraulic cartridge valve manufacturer should have a service life of no less than 1 million times. Yes, it is the basic standard for high- quality hydraulic cartridge valves to use piano steel wire. However, there are details on where the spring is processed and how to test its service life. Most hydraulic cartridge valve manufacturers just purchase springs from processing plants and then assemble them directly. Once there is a quality problem in the spring factory, it also affects the hydraulic cartridge valve manufacturers. Hydraulic cartridge valve manufacturer AAK controls the quality of springs through material selection and testing, based on 3 details: 1.The selection of piano wire is inevitable. 2.The length of the spring must be measured using a caliper, with the unit focused in millimeters. 3.The service life of the spring is controlled by specialized equipment. As shown in the video, hydraulic cartridge valve manufacturer AAK requires each batch of springs to undergo durability fatigue testing using a spring life testing machine. After the spring is inserted into the fixture, select the working mode in the program first, and then set 1 million tests to set the amplitude and frequency of the spring. Adjust the distance between the upper and lower pressure plates according to the length of the spring. After starting the equipment, the reciprocating motion of the connecting rod drives the compression work of the spring. The time and frequency of spring operation can be tracked on the screen at any time. If the spring is less than 1 million times, the program will automatically remind. AAK hydraulic cartridge valve has a service life of over 1 million times, which is the most basic requirement. You can also give it a try!

AAK, ODM Manufacturer of Hydraulic Check Valves for Aircraft

Whenever there is a new sample of AAK hydraulic valves, I must put it on the desk for a few days. Take a look at the hydraulic check valve with the same attitude of appreciating works of art, and taste a cup of coffee. The work is so simple.   The parameters of AAK hydraulic check valves have surpassed most of the domestic hydraulic valve counterparts, and the appearance is also beyond what the 10-year-old hydraulic check valve manufacturers are able to keep pace with. AAK hydraulic valves have no quality complaints for 6 consecutive years. In 2019, AAK hydraulic check valves were used on aircraft by a Russian customer, which is a witness of good quality.   AAK hydraulic check valve, how good is it? See the visual comparison in the picture below. Only from the appearance, the hydraulic check valve produced by 10 years old factory has lost. Not to mention meeting the parameters of hydraulic check valve using in aircraft, they may not dare to think or do it. AAK hydraulic valves is an ODM manufacturer for international first-line hydraulic valve brands. It is difficult to find the third one in Ningbo, the hometown of hydraulic valves. You can also have a small try. https://www.aakindustry.com/info-detai , l/hydraulic-check-valves-aak198
