AAK HYDRAULIC VALVE factory is equipped with high-precision imported CNC lathes and honing machines, designed many small fixtures and special processing equipment for assembly, the production efficiency is 30% higher than that of its peers. Moreover, AAK never cheat customers, ensure quality and delivery time, customer Steven doesn't want to find a second supplier anymore. For the foreign trade hydraulic valve orders, delivery time is very important and critical. The domestic hydraulic valve manufacturers are used to domestic sales. They are not too serious about the delivery date, the production is slow and the workers get off work at the fixed time. If it is urgent, nearly 90% of the hydraulic valve manufacturers will choose outsourcing processing. Different hydraulic valve manufacturers have different quality levels, so the quality of the hydraulic valves is uneven and the delivery time may still be delayed. Choose such a hydraulic valve manufacturer, the full quantity is not guaranteed, and the quality is also difficult to count on. At the beginning of 2020, one of our old customers introduced the American customer Steven to AAK HYDRAULIC VALVE. Steven mainly purchased many hydraulic check valves in the past 2 years. In previous years, he purchased hydraulic check valves in their country. Only the year before last, he started to develop hydraulic valve suppliers in Ningbo and Guangdong. He encountered problems. Some hydraulic check valve manufacturers have limited equipment, production does not conform to the process, and the accuracy of hydraulic valves is unstable, so they have been afraid to place orders. Steven learned from our website and the communication that AAK HYDRAULIC VALVE has several high-precision imported CNC lathes and many small processing equipment, the production line operates 24 hours, and the hydraulic valve technicians take two shifts, each process has strict operation standards, and the output can be 30% higher than that of peers. At the same time, it can ensure the quality of hydraulic valves. Steven placed an order for hydraulic check valves of more than 20,000 US dollars with AAK. It takes only 30 days for AAK HYDRALUIC VALVE to complete the order, because it is the first cooperation, he especially gave us 45 days to produce these hydraulic check valves and required that the delivery date cannot be postponed and the accuracy must meet the requirements. After 25 days, the mass production of the hydraulic check valves was completed 35 days in advance. Steven was a little surprised at the productivity of our hydraulic check valves. 2 months after he received the shipments, he sent us an email that his customers were very satisfied with the quality of the hydraulic check valves, which can be compared with #sun hydraulic #. Steven is pleased to tell us that in Ningbo, he will no longer consider looking for a second hydraulic check valve supplier. AAK HYDRAULIC VALVE is not only willing to spend a lot of money on equipment, but also willing to spend money on technological innovation. The key is that AAK HYDRAULIC VALVE never makes cheat customers. The production line operates for 24h, with high capacity and quality. Its quality is comparable with the international first-line hydraulic valve brands. The world's top 500 enterprises also like the #hydraulic check valves# produced by AAK. Guaranteed Quality, Quantity and Delivery, AAK HYDRAULIC VALVE never cheat, which saves you worry and rest assured. https://www.aakindustry.com/

In October, there were quite a few exhibitions in China, and some hydraulic manifold manufacturers were also participating. Whether it was the Canton Fair or PTC ASIA, we could see the presence of some hydraulic manifold manufacturers. Some customers asked if AAK had a booth, but in fact, the hydraulic manifold manufacturer AAK had not participated in the exhibition for 5 years, not only because of the epidemic, but also because we found that online promotion was better than attending offline exhibitions to get inquiries. Of course, most hydraulic manifold manufacturers do not think so. Many times, it's interesting, and what most people think is probably wrong; What you think is often wrong. The online promotion of hydraulic manifold manufacturers is different from offline communication, and the more important thing is trust. At the beginning of the moment when hydraulic manifold manufacturer AAK focused on the online, I knew it was a completely scriptless journey. Although it took a few minutes to spread every day and there were countless words, it was really nice to meet you online. The status of hydraulic manifold manufacturer AAK spreading to you every day, has been 3 years. So I say that for hydraulic manifold manufacturer AAK, who is currently just like a freshman in the first year, there may be more minor problems, and everything needs to be restarted. But we don't have to look forward to the next 6 years, to graduate from elementary school, go to middle school, high school, or even college, and everything will be natural. Hydraulic manifold manufacturer AAK just wants to be a better version of themselves. When AAK provides text, I also hope to have a better and deeper journey in others' text. Actually it's easiest to walk where to go, but it's actually difficult to navigate through other people's words. Regarding future, let's read more books, focus on the manufacturing quality of hydraulic manifolds, understand the world, and be better ourselves. Don't easily mock others for not having knowledge, because when you mock others, there are countless more knowledgeable people watching us. When you look at the scenery on the bridge, but there are also people looking at you under the bridge, and you are also the scenery. When you gaze at the abyss, the abyss is also staring at you. Let's be runners, because during the process of running, the road will become more solid and we will become more aware. On the way to foreign trade, the hydraulic manifold manufacturer AAK, cannot be constrained and affected by fixed thinking, although some domestic hydraulic manifold manufacturers have some unprofessional old fogies in their trade behavior, hydraulic manifold manufacturer AAK must understand the rules and abide by integrity, which is the foundation of our online survival. From a person to a country or nation, any fate is a product of cultural attributes. A strong culture cultivates the strong, while a weak culture cultivates the weak. The weak are trapped in the cage of thinking, while the strong break the boundaries of cognition. Hydraulic manifold manufacturer AAK in Ningbo China, not big, must be strong.

5 years ago, AAK hydraulic pressure valves started to use 100% Korean piano steel wire as the pressure spring of hydraulic valves, while only a few hydraulic valve manufacturers in Ningbo were using it. Russian customer Natalia placed an order 3 months after receiving our hydraulic pressure valve samples. Finally, AAK HYDRAULIC VALVE became Natalia's only hydraulic valve supplier in Ningbo. Most hydraulic valve manufacturers use carbon steel, which is cheap and widely used, as the valve spool of hydraulic valves. This pressure spring has good hardness, but its plasticity and toughness are very general, its tensile strength is relatively weak and its stability is difficult to control. After the hydraulic pressure valves being used for a period of time, the pressure may not be adjustable. Natalia, a Russian customer, purchased hydraulic pressure valves from Ningbo last year. There was a problem with the automatic pressure regulation. She received many complaints from her customers. Natalia contacted more than 10 hydraulic valve manufacturers, but all the pressure springs from them were not up to standard. Natalia thought of AAK HYDRAULIC VALVE, which may be able to solve this problem. When we received the hydraulic pressure valve drawing from Natalia, she repeatedly stressed the quality of the pressure spring. After discussion, the technical team of AAK HYDRAULIC VALVE promised to send the approval sample of hydraulic pressure valve within 12 days. After we sent the hydraulic pressure valve sample, Natalia only confirmed the receipt and asked us to wait for her comparison results. We have been waiting for 3 months, during which time we sent an email to her, but didn't get a reply, so we held this hydraulic pressure valve. The day before our National Day holiday, I was a little surprised when I received an email from Natalia for the hydraulic pressure valve order. In the following conversation, we learned that she had not only asked us AAK HYDRAULIC VALVE factory to make samples. She contacted with more than 10 hydraulic valve manufacturers totally, and asked 3 manufacturers to make samples and send the samples to their company for testing. The company tested every components and the circulation of the whole hydraulic system. We AAK HYDRAULIC VALVE and another hydraulic valve manufacturer from Guangdong were shortlisted. However, the pressure spring of AAK hydraulic pressure valve has unique skills, and its tensile test parameters are the best. Natalia chose AAK HYDRAULIC VALVE finally. She said that if the quality of this order is no problem, AAK HYDRAULIC VALVE will be their only hydraulic valve supplier in Ningbo in the future. AAK hydraulic valves have always used piano steel wire pressure spring imported from Korea. The material has high strength, good elasticity, fatigue resistance, creep resistance and toughness, smooth and clean surface, strong anti rust ability, specified tensile strength and torsional performance, and the surface will not have cracks, folds, scabs, tensile cracks and corrosion. AAK hydraulic valves are not the common quality in the market, but it is the one that is difficult for you to find several hydraulic valve manufacturers in China that can be compared with us. It's not because we are pride, we're more honest and just tell the truth. You can also try a small order. https://www.aakindustry.com/

Patrick, an old customer in the Netherlands, used to buy our hydraulic cartridge valves. In the first half of the year, he purchased a batch of hydraulic valve blocks from another hydraulic valve manufacturer, but he had received a strange complaint from users in recent weeks. The hydraulic oil deteriorated suddenly. After stopping the machine to check the hydraulic oil, it was found that there were small iron filings inside the oil. After disassembling the whole hydraulic valve, it was found that the valve spool also showed signs of wear. The customer judged that there were iron filings in this batch of hydraulic valve blocks. Patrick discussed with the hydraulic valve block manufacturer about how to deal with this quality complaint. The manufacturer replied that it was the problem of hydraulic oil, not the hydraulic valve block. So this problem was stuck here. Patrick emailed me and asked if I knew this hydraulic valve block manufacturer and whether I could mediate and solve the problem. When I received the drawings of the hydraulic valve block purchased by Patrick this time, I felt that the iron filings probably came from the hydraulic valve block, because the intersecting processing channels of this hydraulic valve block were complex. With Patrick's appeal, I went to the hydraulic valve block factory. The overall feeling of the factory was still good, but the cleaning process before hydraulic valve block packaging did not accord with the process and details in my mind. When I came back, I emailed Patrick. The manufacturer should understand that the problem of iron filings lay with them. However, according to the current iron filings removal process in this factory, even if replenishment, it was difficult to completely avoid iron filings. So he didn't want to reproduce and couldn't solve the problem, he had to perfunctory your demands. Patrick didn't reply to my email for 2 days. When I asked him what else he needed me to do in this matter, he said that he had a big headache these 2 days. The boss asked him to find a new hydraulic valve block manufacturer to replenish part of the hydraulic valve blocks to take care of the customer's dissatisfaction with quality. I reminded him that there were few hydraulic valve manufacturers that could do this type of hydraulic valves with many slender holes. AAK HYDRAULIC VALVE solved a similar problem of iron filings of hydraulic valve block last month, and I sent him the pictures of hydraulic valve block for reference. The next day, Patrick asked us how long it would take to produce 200 hydraulic valve blocks, which was the minimum replenishment quantity required by the customer. When the replenishment order was confirmed, Patrick was relieved. How does AAK hydraulic valve remove iron filings from hydraulic valve block? Firstly, the hydraulic valve block is boiled with high-temperature alkaline water to make the iron filings of the hydraulic valve block lose magnetism, and then the pneumatic small grinding wheel is used to clamp the rotary file to go through the channel once, so as to completely eradicate the possible flash at the corner, and then the high-pressure washing machine is used to wash the dirt on the inner and outer surfaces of the channel under high pressure. Finally, the industrial endoscope and cold light source are used to check the flash burr, then point-to-point high-pressure flushing until the fixed iron filings in the hydraulic valve block are completely eradicated. AAK has unique skills in dealing with iron filings residue in hydraulic valve block. You can also try a small order. https://www.aakindustry.com/info-det , ail/hydraulic-valve-block-aak100

AAK hydraulic cartridge directional control valve adopts a closed unit with 4 faces, which replaces the traditional 2 faces to connect the main flow. The flow rate can reach 760L/min, while the pressure drop is less than 7bar, and the applicable pressure can reach 350bar. It not only improves the stability of the hydraulic system, but also increases the energy consumption of the equipment by at least 20%. Napoleon did not hesitate to give up the original hydraulic cartridge directional control valve manufacturer that had cooperated for 5 years, and chose AAK for the annual order. For personalized customization, it does not only need to benchmark the manufacturing quality of first-line brands, but also need the team knowing 6 aspects, including design, materials, process, technology, production line control and testing. Not a single one can be omitted. However, most of the hydraulic valve manufacturers only have the production capacity according to the drawing, and use traditional technology to produce market goods, which is difficult to meet the personalized requirements of customized equipment. Napoleon is from a hydraulic equipment manufacturing company in Italy. Last year, he asked me about the technical parameters of a hydraulic cartridge directional control valve, then no further contact any more. At the beginning of the year, they customized a hydraulic casting machine for a customer. During debugging, they found that the stability of the equipment was not high, and the operation would lag after it was started. Their engineer judged that the hydraulic cartridge directional control valve was unqualified. Napoleon is very cautious in purchasing. For this hydraulic cartridge directional control valve, he specially selected a supplier who has cooperated for 5 years to make samples. The original manufacturer retested all parameters of the hydraulic cartridge directional control valve, but found no abnormality. Napoleon guessed that the original design may have hidden dangers, but the original manufacturer has no ability to modify the design. Napoleon came to me again and informed me of the current dilemma of the hydraulic cartridge directional control valve. AAK engineer analyzed the drawings of the hydraulic cartridge directional control valve and the video of the equipment operation, judged that the original design had hidden dangers, and also had an improvement plan. We suggest making samples directly. After 45 days, AAK sent 10 samples of hydraulic cartridge directional control valves. 2 weeks later, Napoleon informed that after installing AAK hydraulic cartridge directional control valves, the hydraulic system of the hydraulic casting machine was stable. After it was started, there was no lag, and the energy consumption of the equipment reduced by more than 20%. Their customer was very satisfied. Their company also plans to promote this hydraulic casting machine, and asked me to wait for the annual order for the hydraulic cartridge directional control valve. The design of the original hydraulic cartridge directional control valve adopts the traditional closed unit with 2 sides, one side is connected with the main flow, and the other side is used for control. The position of the closed unit can only be determined according to the pressure ratio between the main flow interface and the control oil interface, and the opening can only depend on the spring. The hydraulic system of the customized equipment of customer is a little special. When such a hydraulic cartridge directional valve is used on the equipment, it has an impact on the stability. AAK hydraulic cartridge directional control valve adopts a 4 face closed unit, adds 2 independent control surfaces, and has an adjustable position "open valve" gear. When closing the valve, there will be no delay, nor the force of the spring, to ensure no lag after opening. AAK hydraulic cartridge directional control valve not only adds new functions, but also improves the original functions. The flow rate can reach 760L/min, while the pressure drop is less than 7bar, and the applicable pressure can reach 350bar. The hydraulic system of the equipment is stable, and the energy consumption is reduced by at least 20%. AAK hydraulic cartridge directional control valve is customized, which is incomparable to the peers.

Kadin is from Turkey. They have many stores selling hydraulic cartridge valves in Turkey, and the market competition is very fierce. At the beginning of last year, Kadin needed to purchase a batch of hydraulic directional control valves benchmarking SUN. AAK also received his inquiry, but we gave up because the target price was too low. Kadin placed the order with another manufacturer of hydraulic directional control valves in Ningbo. 9 months later, a customer complained of severe wear on the valve body edges and leakage from the hydraulic directional control valve. Per the original hydraulic directional control valve manufacturer, he uses industry standard 45 steel to produce valve bodies, which can be guaranteed to be wear-resistant for more than 1 year. If the usage frequency is too high, it can only last for 9 months. Kadin was very helpless. He contacted more than 10 other hydraulic valve manufacturers in China. They all stated that the 45 steel valve bodies cannot guarantee a service life of more than 1 year under high-frequency operating conditions. If using other stronger materials, the price is much higher, which is not suitable for the Turkey market.   Kadin asked what type of steel is the body material of AAK hydraulic directional control valve? After communication, it was learned that he encountered the problem about the valve body not being wear-resistant. I told him that using 45# steel to produce valve bodies is indeed an industry standard, unless there are special requirements on the materials. But the 45# steel valve body can also guarantee a service life of more than 1 year under high-frequency working conditions. Most hydraulic valve manufacturers in China directly use 45 steel to machine and produce valve bodies, while AAK needs to make an action before production to strengthen wear resistance. Although the cost is a bit higher, AAK has always done so. Kadin accepted my original quotation and asked AAK to produce a small batch of hydraulic directional control valves. After 45 days, we delivered 100 pcs of hydraulic directional control valves.   Last week, Kadin placed a re-peat order of 1,000 hydraulic directional control valves, hoping that I could help with the price to better adapt to the competition in the Turkey market. I gave a 5% discount. Why is the AAK valve body made of 45 steel wear-resistant?   AAK uses 45 steel to produce valve bodies, which are first forged and then machined. We use forging machinery to apply pressure on the 45 # steel billet, causing plastic deformation and obtaining certain mechanical properties. After forging, the crystal structure of the steel piece increases by at least 30%, and the existing segregation, porosity, air hole, slag inclusion etc. in the steel ingot are compacted and welded together. The plasticity and mechanical properties of the steel is increased by more than 50%. On the surface, the valve bodies are all made of 45 steel. By comparison, we can see why the AAK hydraulic directional control valve is durable. This is our trick.    AAK hydraulic directional control valve, more durable than its peers, not only material, you can also give it a try!

Hydraulic directional control valve troubleshooting, in only half of the time given by Leo, AAK HYDRAULIC VALVE used Fluororubber Sealing Ring and solved the problem of the hydraulic directional control valve troubleshooting that the other hydraulic valve manufacturers have not been able to solve, so that Leo can sleep at ease.   This morning, just after reading the emails in the office and preparing for a cup of coffee, my colleague forwarded me an international express. I was a little surprised that there was no parcel notice from any customer, who sent the hydraulic valves to AAK?   Will it be a complaint? I haven't met this for several years. I opened the package in fear. There are 5 new hydraulic valves inside. After simple inspection, they should be hydraulic directional valves. Looking at the sending address and person, it turns out that it belongs to the old customer Leo. This guy likes to make this sudden attack.   Open the face book and I ask him, these are hydraulic directional valves. What do you need me to do? Leo said, hydraulic directional control valve troubleshooting, can you do it? I'm not good at the hydraulic directional control valve troubleshooting. He didn't reply. I immediately joked that I'm not good at the hydraulic directional control valve troubleshooting, which doesn't mean that AAK HYDRAULIC VALVE is also not good at the hydraulic directional control valve troubleshooting. AAK HYDRAULIC VALVE valve has its own technical team, which can help you on the hydraulic directional control valve troubleshooting. Leo commanded that I have 3 hours to go to bed. Give you 2.5 hours to finish the hydraulic directional control valve troubleshooting. I need to know where the hydraulic directional control valve troubles are and your solutions to the hydraulic directional control valve troubleshooting.   After learning about his use scenarios of these hydraulic directional valves and media, I immediately asked AAK HYDRAULIC VALVE technical team to finish the hydraulic directional control valve troubleshooting within 2 hours. The AAK HYDRAULIC VALVE technical team simulated the use scenario of Leo's hydraulic directional valves under the pressurization and flow scenario. The test report came out soon. There were problems with the sealing rings of these hydraulic directional valves. At the same time, we suggested him use Fluororubber sealing ring to seal this hydraulic directional valve.   We took 1.5 hours to finish the hydraulic directional control valve troubleshooting, which is just half of the time given by Leo. After learning the result, Leo was relieved and could sleep at ease. The story turned out to be this: Leo purchased some hydraulic directional valves, 30% of the hydraulic directional valves have flow parameter problems. The hydraulic valve manufacturer has not been able to have solutions to the hydraulic directional control valve troubleshooting. The boss is very unhappy.   I told Leo that nearly 90% of the domestic hydraulic valve manufacturers use either silicone sealing rings or nitrile rubber sealing rings. They rarely think about different media and different hydraulic scenes or use the appropriate sealing rings according to the media. They all follow the market, just use what other people use. We AAK HYDRAULIC VALVE, as early as 5 years ago, have carried out material analysis for the pain points of sealing rings. After comparison, we have formulated different parameter requirements, different media and different scenarios to correspond to sealing rings of different materials. For example, the sealing performance and stability of fluororubber sealing ring are most suitable for the hydraulic directional valves purchased by Leo.   AAK has targeted Technology on the hydraulic directional control valve troubleshooting, contact AAK if you have needs for the hydraulic directional control valve troubleshooting. https://www.aakindustry.co , m/

There is a hydraulic cartridge valve manufacturer engaged in valve foreign trade. Recently, they had some inquiries about hydraulic cartridge valves, but after replying, the customer had no further information. For foreign trade operations that he doesn't understand, he usually asks me for help. The hydraulic cartridge valves and hydraulic manifolds produced by AAK, have been exported for 13 years, and in his heart, AAK is his benchmark. I asked him, how did your salesperson respond to customer emails? According to the manufacturer of the hydraulic cartridge valves, the communication is like below: Customer A: I am very interested in your MP08-30. Can you send me your price? Reply from the manufacturer of the hydraulic cartridge valves: Please inform us of your quantity? Customer B: Do you have inventory of MP08-30? I want to buy 2 samples for testing first. Reply from the manufacturer of the hydraulic cartridge valves: Can you tell me your email address or WhatsApp number? Perhaps someone may ask, is there anything wrong with the replies to these two inquiries? In the eyes of experienced sales personnel from many hydraulic manifold manufacturers in China, the reply is normal and has no problems. This is actually a typical Chinese style of thinking. The sales of hydraulic manifold manufacturers, and even most experienced sales bosses of hydraulic manifold manufacturers, believe that there is a good price for good quantity, and that price optimization for big quantity is quite popular in China. So, salespeople are often tied down by this domestic trade mindset. For the question 'how many do you want', most foreign buyers are averse to the reply and question like this. From his perspective, the hydraulic manifold manufacturer did not give me a price, nor did they tell me about the hydraulic manifold functions and performance, nor did they express some of the characteristics, advantages, or professionalism of the hydraulic manifold manufacturer itself. So, the salespeople of hydraulic manifold manufacturers should not be constrained by many fixed trade thinking in China. Apply this mindset to foreign buyers, and they will ignore you. Some very realistic ideas and cultures may not be a problem for Chinese people, but when applied to foreign buyers, it may be counterproductive. Therefore, in the view of hydraulic manifold manufacturer AAK, the correct order should be: first, introduce the hydraulic manifold manufacturer AAK before a quotation, then go to the specific details of the inquired products (such as parameters, functions, performance, selling points, etc.), and finally return to the price link or quantity inquiry, so that the buyer feels much more comfortable. For customer inquiries left on the internet, such as those from customer B of the hydraulic cartridge valve manufacturer mentioned above, many buyers do not often log in to the platform to read the replies of the hydraulic cartridge valve manufacturer. Therefore, the salesperson immediately asks the buyer to provide their email or WhatsApp and other contact information for follow-up. At first glance, there is no problem. In China, telemarketing is quite common. If one day a salesperson calls you to promote a product, describes the product letter, and asks you for other contact information such as QQ or WeChat, are you willing to give it? Similarly, in the eyes of foreign buyers, it is indeed inappropriate for you to ask them for other contact information in a very abrupt manner. Many foreign buyers, some of their contact information is personal, and their communication with you now is based on work. They distinguish work and personal life very clearly, and they do not want you to disturb them during their non work hours. The foreign trade salesperson of a hydraulic manifold manufacturer should not immediately ask for the buyer's other contact information, but can first have preliminary communication with the buyer, accept your products and services, and let the buyer have a certain interest in you before naturally asking for their contact information. He would be more willing to give it to you. On the foreign trade path of hydraulic manifold manufacturers, they often encounter buyers who say they have found same or similar products from other hydraulic manifold manufacturers, and the prices are lower than yours. At this point, most hydraulic manifold manufacturers replied: 'You get what you pay for, our quality is better. That company's quality is not good, and this low price is definitely for products with quality issues.'. This is also a typical Chinese way of thinking in foreign trade, and 99% of the time this explanation may not have any effect. Firstly, their prices are lower than yours. To prove that your product has better quality and more complete performance, you need to provide evidence, facts, or customer cases. The truth that facts speak louder than words is understood by both Chinese and Western people. Secondly, many foreign buyers do not like one supplier very much who slanders the product quality of another supplier, which in their view is a particularly despicable business competition behavior. In the final analysis, these foreign trade responses mentioned above are all constrained and influenced by fixed thinking, and most hydraulic manifold manufacturers find it difficult to jump out of it on the foreign trade path. Hydraulic manifold manufacturers use these ideas to communicate with buyers, especially Western customers, and there is basically no response. Whether hydraulic cartridge valve manufacturers or hydraulic manifold manufacturers, there are some very unprofessional and old-fashioned phenomena in domestic trade. For example, the delivery time of the manufacturer is not guaranteed, the promised delivery time of the manufacturer is 4 weeks, and the actual delivery time is more than 10 days. For example, when you confirmed the quote and placed an order, this hydraulic manifold manufacturer will increase the price for you, or another hydraulic manifold manufacturer mentioned material cost increase and need a new price. Hydraulic manifold manufacturer AAK in Ningbo China, on the road to foreign trade, understands rules and adheres to integrity.

Pedro, one of our old Brazilian customers, introduced AAK to Joao in August last year. I thanked Pedro for his trust, but also requested myself to thoroughly solve the problem of hydraulic pilot operated pressure control cartridge valve encountered by Joao for the trust of Pedro. Trust is the lifeline of AAK cartridge valve, whether it is the production, promotion or marketing of cartridge valves. Joao's customer tried to order 5 sets of hydraulic power units, but the commissioning was not smooth and the equipment vibrated too much. Their engineer believed that the hydraulic pilot operated pressure control cartridge valve purchased by Joao was not up to the standard, and the change of the pilot pressure was delayed, resulting in the actuator action delay and vibration. The original manufacturer of the hydraulic pressure control cartridge valve said that it was manufactured according to the customer's drawings and the accuracy was up to standard. Joao was caught between supplier and engineer, which was very embarrassing.   Joao contacted his friend Pedro, which gave the opportunity for AAK cartridge valve to perform. Joao's first email to us is as follows: Pedro told me that if there is any difficulty in cartridge valve, just contact AAK. I stayed at AAK cartridge valve website for more than 7 minutes. The fact that AAK solved difficult problems for customers showed me hope. I told him that to avoid equipment vibration, the response speed of the hydraulic pilot operated pressure control cartridge valve should be increased first, and the pilot pressure should not lag, so as to avoid the opening lag of the counterbalance valve in the system. After 45 days, AAK sent the samples of hydraulic pressure control cartridge valves.   Last week, Joao sent an email to inform us that with AAK hydraulic pilot operated pressure control cartridge valve installed, the commissioning of the hydraulic power unit was smooth and there was no vibration. The customer was also satisfied. AAK hydraulic pilot operated pressure control cartridge valve can improve the opening lag of the counterbalance valve in the system, because we have made innovations in 3 aspects, which most cartridge valve manufacturers have not expected.   1. The vent cavity, ejector hole and control cavity of the hydraulic pressure control cartridge valve body are on the same axis. The side wall of the valve body is provided with an oil outlet connecting the control chamber and the inclined hole. The two oil ports of the valve body are respectively connected with the main oil circuit and the control chamber of the hydraulic system, forming two parallel connection channels.   2. The spring seat of the hydraulic pressure control cartridge valve is located at the bottom of the ventilation chamber, the adjusting sleeve is threaded in the ventilation chamber, the adjusting bolt is connected in the threaded hole on the adjusting sleeve, and the first connecting channel has fixed hydraulic resistance parts connected in series with small holes.   3. The side wall of the valve seat of the hydraulic pressure control cartridge valve is provided with a small hole to connect the inner hole of the valve seat with the annular cavity. There is a steel ball in the lower cavity of the valve seat. A return spring is installed in the cavity at the upper part of the valve base. The upper end of the ejector rod conflicts with the lower end of the spring seat, while the lower end of the ejector rod conflicts with the steel ball. The outer circumference of the ejector rod and the inner hole of the valve seat form a circular gap.   AAK hydraulic pilot operated pressure control cartridge valve, fast response, no vibration, you can also try it! https://www.aakindustry.com/info-detail , /pressure-control-cartridge-valves- aak513

Zander is from a hydraulic manufacturing company in Greece. In the first half of this year, their company planned to upgrade the old logistics crane and put it back on the market. Its main goal is to improve its stability by 20% compared with its peers. The optimization of the hydraulic cartridge counterbalance valve is the key, but the original hydraulic cartridge counterbalance valve manufacturer has no ability to innovate. Zander found a local hydraulic cartridge valve manufacturer to optimize the structure and make samples. However, during commissioning, when the load of the system drops, the pressure fluctuation cannot exceed that of the peers, and the hydraulic cartridge counterbalance valve cannot avoid load interference. The local hydraulic cartridge valve manufacturer has no ability for further improvement. 2 months passed by, but there was still no solution. The boss pushed for progress many times, and Zander was worried. Zander found AAK on Google, noticed that AAK had released some customer cases about hydraulic cartridge counterbalance valves, and sent us an email. According to the schematic diagram of the hydraulic system and the original hydraulic cartridge counterbalance valve drawing provided by him, AAK engineer informed that the structure optimized by his local hydraulic cartridge valve manufacturer was not reasonable and needed to be adjusted. AAK has a trick to prevent the hydraulic cartridge counterbalance valve from being affected by the load. Zander asked for AAK samples. After 45 days, AAK sent 20 samples of hydraulic cartridge counterbalance valves. 3 months later, Zander sent an order for 500 hydraulic cartridge counterbalance valves, and told us that their technical department was very satisfied with AAK hydraulic cartridge counterbalance valves. Not only did they overcome the load impact, but also improved the stability of their new logistics crane by more than 20%. In the promotion stage, the booking was good, and the boss was happy. AAK hydraulic cartridge counterbalance valve can stably control the opening of the valve spool without being disturbed by the load, and its stability is higher than that of its peers, because we have tricks on optimizing the structure. AAK hydraulic cartridge counterbalance valve is composed of a valve body, a valve seat, a main valve spool, a pilot valve spool and a pilot mechanism. The valve seat is connected with the valve body and forms a connected first channel. The extended end of the valve seat butts against the pilot mechanism and forms a second channel. The main valve spool is provided with a throttling slot. One end of the pilot valve spool slides and is arranged in the inner cavity of the main valve spool. The other end is connected with the pilot mechanism. The pilot valve spool is equipped with a throttling slot. The pilot valve spool is connected with the inner cavity of the main valve spool as a balanced structure. The force of the pilot mechanism can balance the oil pressure in the oil passage on the pilot valve spool. Therefore, the opening of the main valve spool is not affected by the load pressure wave. AAK hydraulic cartridge counterbalance valve, free from load interference, you can also have a small try! https://www.aakindustry.com/info-detai , l/counterbalance-valves-aak440

The hydraulic needle valves produced by AAK has no leakage and its stability exceeds that of most of its hydraulic valve peers, enabling a foreign trade company in Guangdong to save a major global top 500 customer. The key is that AAK adopts high-precision processing equipment imported from Switzerland to produce hydraulic needle valves. At present, there are less than 5 hydraulic valve manufacturers with such high configuration in the hometown of hydraulic valves in Ningbo. Most hydraulic valve manufacturers use CNC lathe to produce hydraulic needle valves. The hydraulic needle valves made by CNC lathe has high technical requirements for operators and is prone to human errors, such as the valve spool deviates from the central axis. Because of human error, the hydraulic needle valve leaks, and it is not easy to judge which part has the problem. At the end of last year, Mr. Wang, the general manager of a hydraulic valve export company in Shanghai, received complaints from major customers about the several batches of hydraulic needle valves, which made them in a mess. Under the introduction of friends, he came to our company and brought those hydraulic needle valve samples with problems. After inspection, it is found that the main line of the hydraulic needle valve is offset, and the valve spool deviates from the central axis. I told him that this problem is easy to solve and also easy to cause problems. Only with a better CNC lathe can it be guaranteed. We provided him the test data of AAK hydraulic needle valves for comparison, and also asked him to take several hydraulic needle valve samples at random and send them to his customer to compare with the domestic peers. More than half a year later, there was still no reply from Mr. Wang. I didn't know how difficult it was for a top 500 enterprise to place a new order until I had a telephone communication with Manager Wang for more than 30 minutes last week. After Mr. Wang went back last time, he wanted to send the samples of AAK hydraulic needle valves to the major foreign customer, a global top 500 enterprises. At first, the customer refused until their overseas colleagues came to visit with the samples of the hydraulic needle valve to test the samples together on site. After the test, the customer was very satisfied with the quality of the hydraulic needle valve samples, which not only had good surface gloss, high precision, but also had strong sealing performance. Customer is willing to place a trial order first. As long as the quality of the mass production is the same as the samples brought, they can continue to purchase all kinds of hydraulic valves from their company. Mr. Wang asked us to work together to keep this global top 500 customer. In order to achieve zero leakage of the hydraulic needle valve, AAK HYDRAULIC VALVE has imported the highest precision production equipment from Swiss to make up for the short board of CNC lathe. At present, less than 10% of the peers have this equipment. It can replace 7 groups of accessories at random. The high-pressure hydraulic needle valve produced by Swiss equipment has high precision, which is at least 20% higher than that of domestic conventional CNC lathe. Not only high precision, but also stability. The zero leakage AAK hydraulic needle valve is being used by global top 500 enterprises. You can also try an order.

Under the pressure and flow conditions, AAK hydraulic valve effectively controls the sealing ring of each hydraulic valve, so it always ensures that the flow parameters in the hydraulic directional valve system are at the normal value. Only a small detail of the sealing ring has made the reputation of AAK hydraulic valve exceed that of many domestic and foreign peers. I will not modest about this. Many hydraulic valve manufacturers are used to domestic sales and are used to dogmatic production. Maybe they can copy the production process of their peers and continue to use some traditional technologies, but they may be helpless on the details or hidden problems of some spare parts. Leo, an old customer, suddenly sent me 3 samples of hydraulic directional valve some time ago. I didn't receive any email about these samples of hydraulic directional valve in advance. So I thought Leo asked us to offer a quotation. After receiving the hydraulic directional valve samples, I asked him by e-mail how many quantities he needs and what scenario this hydraulic directional valve will be used, then I would give him the plan of this hydraulic directional valve. However, Leo didn't need my quotation, just let me judge the quality of these hydraulic directional valves. Sending samples to let me just see the quality without doing other actions. This was the first time I had met. After testing these hydraulic directional valve samples, AAK HYDRAULIC VALVE technical team found the overall quality was good. The only hidden danger was that the flow parameters of one of the hydraulic directional valves were a little unstable, which should be adjustable in use. I directly told Leo that these hydraulic directional valves were qualified, but he should pay attention to flow adjustment during use. Leo's email reply surprised me again. Leo said that no wonder he stumbled in purchasing these hydraulic directional valves. Even AAK HYDRAULIC VALVE couldn't find problems with these hydraulic directional valves. I angrily asked the technical team to test these hydraulic directional valves again and simulate the use scenario of Leo's hydraulic directional valve under the pressurization and flow scenario. The test report came out soon. There were problems with the sealing rings of these hydraulic directional valves. Leo was relieved when he learned of the result and found the root of the problem. 30% of the hydraulic directional valves he purchased this time had the problem of flow parameters lower than the standard parameter values required by customers. His hydraulic valve manufacturer had been unable to find the root cause of the problem. He never thought it was caused by the mismatch of sealing rings. The traditional nitrile rubber sealing rings were not suitable for hydraulic scenes. I told Leo that nearly 90% of the domestic hydraulic valve manufacturers use either silicone sealing rings or nitrile rubber sealing rings. They rarely think about different media, different hydraulic scenes, and adjust the appropriate sealing rings according to the media. They just follow the market and use what other people use. We AAK HYDRAULIC VALVE, as early as 5 years ago, had conducted material analysis for this technical pain point. After comparison, we specified different parameter requirements, different media and different scenarios to correspond to different material sealing rings. For example, the sealing performance and stability of fluororubber sealing ring are most suitable for the hydraulic directional valve required by Leo’s customer. AAK hydraulic directional valve has details and targeted technology. You can try a small order.

Today, AAK posted a solenoid cartridge valve E-SF08-20, benchmarking HydraForce SF08-20. It is a solenoid-operated, 2 way, normally closed, piloted poppet- type, screw-in hydraulic cartridge valve and intended to act as a blocking or load-holding device for low flow circuits. Many hydraulic valve manufacturers in Ningbo China do not have this model. One of our customers in Brazil checked with 7 hydraulic solenoid valve manufacturers in 3 months, but none of them have this solenoid valve. He was very happily to get it from AAK, and the manufacturing quality and performance is equivalent to HydraForce SF08-20. The selling points of this solenoid cartridge valve are: 1. Internal Leakage: 3 drops/min 2. Benchmarking HydraForce SF08-20 Technical parameters of AAK E-SF08-20 NORMALLY CLOSED SOLENOID CARTRIDGE: Max. Operating Pressure: 350 bar (5000 psi) Internal Leakage: 3 drops/min max. at 350 bar (5000 psi) Temperature: - 40 to +120 °C (with Standard Buna N seals) Cavity: 08-2 For this normally closed Solenoid Cartridge Valve, the quality is benchmarking HydraForce SF08-20, you can also try it out.

A few days ago, hydraulic cartridge valve manufacturer AAK released an article titled "The cleaning of hydraulic solenoid cartridge valve SV08-20, is not refined on by every hydraulic cartridge valve manufacturer ". Dotan from Israel left a message: "We have a customized hydraulic cartridge flow control valve from Israel, with a slightly special contour of the valve cage. The original manufacturer of the hydraulic cartridge flow control valve was also equipped with hydraulic valve ultrasonic cleaning equipment, but there are still a few hydraulic cartridge flow control valves with residual impurities, and customers are not very satisfied. The hydraulic cartridge valve manufacturer also has no good solution.”. According to the pictures sent by Dotan, the cleaning of the hydraulic cartridge flow control valve is not a one-time solution. I told Dotan that the stability of the quality of these special products often tests the details and even micro details of the hydraulic cartridge valve manufacturer, such as AAK's innovative ultrasonic cleaning process for hydraulic valves and the three-step cleaning process, which reflect AAK's focus on details. But often behind a detail, there are also some micro details to lay the groundwork. Imitation of details may not be difficult, but can we continue to focus on details and explore more details? This tests the quality awareness and innovative spirit of a hydraulic cartridge valve manufacturer. The cleaning of this hydraulic cartridge flow control valve must require ultrasonic cleaning before packaging, but there is still a risk of impurities in the valve cage. AAK's suggestion is to clean the valve cage before assembling the hydraulic cartridge flow control valve. I sent an old video to Dotan about how AAK cleaned the valve cage. The next day, Dotan advised that their original hydraulic cartridge valve manufacturer did not have such a micro detail like AAK to clean the valve cage first. The key to cleaning special valve cages lies in careful operation and the proportion of cleaning oil. AAK formulates its own cleaning oil based on the characteristics of impurities, which does not stick to metal surfaces. The cleaning process is then set to tap water mode, utilizing the potential energy of the liquid to impact. In combination with a manual brush, clean all parts of the valve cage, especially the concave corners, and finally rinse the oil port with clean oil. After cleaning, place it on a tray and dry it before entering the assembly process. AAK hydraulic cartridge flow control valve, with details, and further micro details, you can give it a try.
