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 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).

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

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 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

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.

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!

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!

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

Caspar is from a hydraulic transmission equipment company in Canada. He has been in purchasing for 5 years, and it is very smooth. In the first half of this year, a batch of hydraulic transmission units they sold was complained by customers that they often had cavitation. The first judgment should be that the hydraulic cartridge pressure control valve in the hydraulic system is abnormal, but the engineer thought that the valve was from the SUN hydraulics and should not have problem. He subconsciously thought that the hydraulic pump that Caspar purchased from China had a leak. After the test, it was found that the pressure at the outlet of the pump was stable. After checking one by one, only hydraulic cartridge pressure control valves from SUN were not checked, but the valve parameters were normal. The engineer was puzzled. After communicating with each hydraulic component manufacturer of the equipment, Caspar came to the conclusion that this SUN hydraulic cartridge pressure control valve may not be suitable for this hydraulic transmission equipment. However, none of the manufacturers of hydraulic cartridge pressure control valves can solve the hidden danger of cavitation, so they can only turn to SUN for help. But SUN was not interested in customizing small quantities. Caspar was helpless and anxious. Caspar found AAK while browsing Google. According to our background trace, he stayed on AAK website for more than 30 minutes, and left a message: Is the cavitation of the equipment caused by the hydraulic cartridge pressure control valve in the system? This needs to be specifically analyzed, according to SUN standard part number, hydraulic schematic diagram, equipment technical parameters, and used scenarios, AAK engineer believed that the SUN hydraulic cartridge pressure control valve of this model does not meet the special requirements of the equipment. AAK can sample the hydraulic cartridge pressure control valve, and it is 90% sure to solve the cavitation complaint. After 45 days, 10 samples of hydraulic cartridge pressure control valves were sent out. Last week, Caspar emailed that there was no cavitation after AAK hydraulic cartridge pressure control valve was used. The customer was very satisfied, but still had to continue to observe for several months. I told Caspar that AAK hydraulic cartridge pressure control valve had eliminated the cavitation hazard of the equipment in terms of function. As long as AAK hydraulic cartridge pressure control valve is within the service life, cavitation will not occur. How did this hydraulic cartridge pressure control valve replace SUN standard parts in function? In AAK hydraulic cartridge pressure control valve, there are two valve spools, separated by a spring, which is fixed in between 2 valve cages. The set value of overflow pressure can be set by adjusting the valve cage. At the same time, there is a damper between the two valve spools, which can provide positive damping of the hydraulic system. The valve can limit any input pressure in the inlet pipeline, prevent impact or pressure fluctuation when the actuator changes direction or stops suddenly, and also allow oil to enter the low pressure pipeline to supplement the oil drainage or any discharged flow. Its two-way cross type function can deliver the discharged oil to other pipelines to ensure the actuator is refilled with oil and eliminate cavitation. AAK customized hydraulic cartridge pressure control valve has more functions than SUN, and you can also have a small try! https://www.aakindustry.com/info-detai , l/cartridge-pressure-control-valves- aak398

Some time ago, Sean, who had purchased hydraulic cartridge valves from AAK for 7 years, suggested me opening up a production line for hydraulic motors. Without thinking about it, I replied that I currently do not have this capability. AAK currently focuses only on hydraulic cartridge valves, hydraulic valve blocks, and hydraulic manifolds. Sean didn't quite understand, but he was willing to support AAK to develop hydraulic motors. My understanding is that specializing in a subject requires 10 years, which is 10,000 hours of deliberate practice. I'm not a talent, so I use 10,000 hours as a ladder for my progress. The production of hydraulic cartridge valves, hydraulic valve blocks, and hydraulic manifolds takes a lot of time. The network promotion and sales of hydraulic cartridge valves, hydraulic valve blocks, and hydraulic manifolds require not only time, but also skills. Especially, AAK's customers, 100% of whom are from the Internet, need to regularly write product manuals, and pay attention to the flow of the network. At present, there is a large flow of cognitive, philosophical, and chicken soup jokes on social media, indicating that people's psychological state is generally anxious. Tragic stories always have a lot of traffic. People like to see others living worse than themselves, and they have a sense of satisfaction and comfort inside. I'm not the worst, many people are much worse than me. Foolish stories always have a large flow, and people are immersed in the Dack effect. The more they see others being so foolish, the more confident they become. Doing e-commerce and self media really requires thinking with traffic, if it is small and almost meaningless. AAK hydraulic cartridge valves, hydraulic valve blocks, and hydraulic manifolds, adhere to doing so, and think with trust. Any order for hydraulic cartridge valves, hydraulic valve blocks, and hydraulic manifolds that requires quality is almost always a product of trust. Trust is the cornerstone of AAK. The instructions for hydraulic cartridge valves should be frequently written and sorted out. Reading and writing are two different things. Writing out is a process of sorting out. And every time I sort, there will be new discoveries, which will help me understand my own products and introduce them to customers. This morning, I used another method to sort out my 3 hydraulic cartridge valves benchmarking SUN. Suddenly, I found this new discovery: If I don't do it one day, I can't see the difference; 30 days without doing anything, just a little short; If you don't do it for a year, there's a big gap. The vast majority of people only stay in understanding and knowing, but as long as they do it, they don't understand or know. The vast majority of hydraulic cartridge valve manufacturers will not modify their instructions for 3-5 years once they have completed them. AAK hydraulic cartridge valves, do things that 90% of their peers are unwilling to do, resulting in a group of high-quality hydraulic cartridge valve customers. https://www.aakindustry.com/ , info-detail/cartridge-valve-manufacturer-aak542

The situation of the economic environment at home and abroad, the lack of market confidence, and the willingness of people to consume, is very low. In fact, the more at this time, the more we need to polish our product quality. As a hydraulic manifold manufacturer, AAK adheres to the principle of "quality is 1". With the leadership of "1", the following matters will be meaningful. Even if a zero is added, it will be 10 times more effective. We look at the quality of our hydraulic manifolds from 3 perspectives.   AAK hydraulic manifold is not a large enterprise. As a representative of small and medium-sized enterprises, AAK aims to target the top 500 global enterprises, global famous enterprises and listed companies to do hydraulic manifolds. Get a big order from a first-line brand, do things with a sense of integrity and mindfulness. With this manufacturing quality 1, following with marketing, sales, these 0's will be useful.   1. Manufacturing quality of hydraulic manifolds We won't talk about the quality of AAK's service first. The customer will have a say in whether the service is good or not. If the manufacturing quality of hydraulic manifold is good, I have the most say. What is related to the manufacturing quality of hydraulic manifolds? AAK thinks it from 5 aspects:   1) The first is related to raw materials. Can I use A+ steel to replace A materials used by peers? For each trial order of AAK hydraulic manifolds, we first consider the material options. To compare what materials are used for hydraulic manifolds of domestic peers, and what materials are used for hydraulic manifolds of international first-line brands? Can AAK use A+ steel to replace material A used by its peers?   2) It is related to the advanced level of technology. The quality of the yarn produced by the same batch of cotton from the same place of origin in different textile mills is different. Why? The process is different. It is the same for hydraulic manifolds, different manufacturers, even if they are all produced with the same materials and equipment, will distinguish between different processes and quality. AAK is good at simplifying the hydraulic manifold oil circuit, and uses targeted process matching to reduce energy consumption.   3) It is related with equipment. Hydraulic manifold equipment is produced in Switzerland, Germany, America, Taiwan and China. The equipment is different, and the manufacturing quality is also different. AAK pays attention to the accuracy of the equipment, and is good at grafting personalized fixtures to ensure efficiency and stability.   4) It is related to processing technology. For example, for the processing of some special valve holes, AAK abandoned the conventional processing technology and adopted customized processing.   5) It is related to quality Control. In the whole production line, from material selection to each process, there are standards and quality inspection.   The manufacturing quality of AAK hydraulic manifolds focus on these 5 points. The manufacturing quality of hydraulic manifolds lies in slow and solid efforts of intelligent people. There is no shortcut to this road. There is no safe haven. Without manufacturing quality 1 takes the lead in the front, all 0’s added later will eventually return to zero. Just like life, whether you can stand on the waves and whether you can hold on the bottom of the waves.   2. Parameter performance of hydraulic manifolds AAK hydraulic manifold has stable performance, basically no failure, long service life and low energy consumption. These are the benefits AAK brings to customers.   The hydraulic cartridge valves are the core components of hydraulic manifolds, and AAK hydraulic cartridge valves are targeted at SUN, HydraForce and HAWE. We often dissect their new models, learn design, refine elements, analyze process, optimize technology, and gradually form a complete AAK hydraulic manifold system from the original design, processing drawings, material selection, material heat treatment, process sheet, processing technology, assembly, and testing. For Hydraulic manifold design, we have a complete process. From hole checking, wire network connection, hole network to component selection, oil circuit volume and assembly, all are linked to each other. AAK hydraulic manifold occupies less space, has less pressure loss, less leakage and less vibration. 3. The innovation of hydraulic manifold function In terms of personalized customization of hydraulic manifolds, it is not difficult to combine, vary and graft some hydraulic unit structures to create something new.   For example, the four-way AAK hydraulic manifold control system is composed of pilot control valve group, 4 two-way cartridge valve control components, manifold blocks and connectors. It has 4 main channels, several pilot control channels, and 2 external mounting surfaces, which greatly reduces component selection and adds the function of flow regeneration. This is technical work.   AAK hydraulic manifold oil circuit is designed into a network structure. The oil return is not only uniform, but also multi way oil return, which reduces the plugging holes in the oil circuit, simplifies the hydraulic manifold hole circuit, improves the oil flow capacity, and reduces energy consumption. AAK hydraulic manifold reduces pipeline connections and joints, reduces system complexity, and reduces energy consumption. It features compact structure, convenient installation, less maintenance, less leakage and small vibration.   AAK is Honeywell's hydraulic manifold supplier for 6 consecutive years. What are the advantages of purchasing hydraulic manifolds from AAK? In the words of Honeywell's purchasing director, it is 3 savings: time saving, cost saving and link saving.   1) Shorten the whole procurement process: plugs, connectors and manifold blocks can be produced in AAK. Procurement and tracking from multiple factories have become a one-stop process at AAK. 2) The installation process is simplified: AAK hydraulic units or manifolds can be directly installed into the equipment, and customers do not need to test the manifolds separately. 3) Undertake design services: from the hydraulic principle, oil circuit design, hydraulic cartridge valve selection, AAK can do 100% personalized customization.   AAK hydraulic manifold defines quality from 3 aspects. Focus on quality 1 and bring benefits to customers. https://www.aakindustry.com/info , -detail/hydraulic-manifolds-aak465

At the weekly meeting of hydraulic valve sales, I always ask our business team to study the production process of hydraulic valves with heart, observe the production of hydraulic valve at the workshop with heart, and think about customer emails with heart. Last month, someone asked me what is with heart? I was speechless for a moment. Recently, I saw an explanation in a book. The difference between using your heart and not is whether you are accepting the world as it is or observing how such a world will affect you? I think the explanation about the difference is in place and hit the nail on the head. Reading the email from hydraulic valve customer, word by word, and even forcibly reciting the whole email, which is still not called reading it carefully with heart. Reading with heart means thinking about these questions repeatedly in the process of reading: 1.What question is the customer asking or requesting about the hydraulic valves? 2.Do we have any problems with these hydraulic valves? If not, how to convince customers that we don't have these problems. 3.Is the answer we are going to provide persuasive? How can customers trust AAK hydraulic valves with the least amount of time? 4.These hydraulic valve problems raised by customers broaden my vision? If it is widened, what is the problem with my original frame about hydraulic valves? 5.Have I understood the customer's needs and emotions? If not, what's my problem? When you read the emails with these questions, you will find that we are not reading the emails, but observing our changes through external stimulation, and even receiving the customer's emotion. This is called reading the emails carefully with heart. AAK team works hard on the hydraulic valves with heart, and understands the needs of each customer with heart. This is our eternal direction! https://www.aakindustry.com/info , -detail/hydraulic-valves-aak197

This week, we’d like to introduce a Hydraulic Cartridge Counterbalance Valve equivalent to SUN standard part CBBA. Counterbalance valves with pilot assist are meant to control an overrunning load. The check valve allows free flow from the directional valve (port 2) to the load (port 1) while a direct-acting, pilot-assisted relief valve controls flow from port 1 to port 2. Pilot assist at port 3 lowers the effective setting of the relief valve at a rate determined by the pilot ratio. In the year of 2022, a new customer from Turkey sent us inquiry for SUN model CBBA cartridge counterbalance Valve, 10 pcs for trial order and 100 pcs for annual order. After we quoted the price, we were advised that the competition in Turkey market is very fierce, AAK price is too high. That was not the first time that we received this type of feedback from Turkey customers, so we did not expect to receive any order from this customer. However, in September of 2022, the customer sent us inquiry for CBBA cartridge counterbalance Valve again. Feeling the real needs of this customer, AAK gave a 8% discount and the customer placed the trial order for 10 pcs of samples for testing. After that, we did not receive any further news from this customer. We thought that the customer may not approve the quality of AAK samples. Unexpectedly, 1 year later, in December, the last month of 2023, we received the regular order for 100 pcs of CBBA hydraulic cartridge counterbalance valve. Then we know that actually, AAK samples passed the testing, due to the earthquake in Turkey and some internal changes in the company, the customer’s buying plan was affected, so they held the order. AAK hydraulic cartridge counterbalance valve 2 advantages: 1. Function and Performance benchmarking SUN 2. Its service life is 2 times that of its domestic peers Technical parameters of AAK E-CBBA 3:1 pilot ratio, restrictive counterbalance valve: Max. Operating Pressure: 280 bar (4000 psi) Flow: 20 L (5 gpm) Internal Leakage: 5 drops/min Temperature: - 30 to +120 °C (with Standard Buna N seals) Cavity: T-11A Fluids: Mineral based or synthetic hydraulic fluid with lubricating properties Fluid Viscosity Range: 7.4 to 420 cSt AAK E-CBBA hydraulic cartridge Counterbalance Valve, equivalent to SUN CBBA, and the service life is 2 times of its domestic peers.
