Kate, the buyer of Terex company, was asked by the head office last month to purchase a batch of hydraulic pressure valves within 3 months. She vowed to the boss that it would be completed in 2 months. As usual, Kate sent the hydraulic pressure valve inquiry to more than 10 hydraulic valve manufacturers she was familiar with, including American hydraulic valve manufacturers and Chinese hydraulic valve manufacturers. She chose 3 factories to provide hydraulic pressure valve samples for testing. After the test, the technical department informed that only the hydraulic pressure valve samples provided by American manufacturer were qualified. The trouble is that the price of the qualified hydraulic pressure valve exceeds 40% of the company's budget price. She has no authority to decide to use the products of this American hydraulic valve manufacturer. After discussion with the technical department, she learned that those unqualified hydraulic pressure valves are mainly due to the wear or fracture of the sealing ring after 15,000 times of impact during the durability test of the hydraulic pressure valve, resulting in the leakage of the hydraulic pressure valve. Only those hydraulic pressure valves that have not leaked for more than 40,000 times are qualified. She was very depressed that the quotation of the other 3 hydraulic pressure valves was within the budget, but the quality was unqualified. At this time, Kate realized why the company gave him 3 months to purchase. She hurriedly sent inquiry to new hydraulic valve manufacturers, and specially emphasized the need for hydraulic pressure valves with more than 40,000 durability tests. The trouble is that no hydraulic valve manufacturer gave her an offer. Kate realized the difficulty of procurement. She had wasted 3 weeks. Procurement was still in its infancy, and the technicians had been urging progress. After learning about Kate's purchase status, the colleague recommended her to contact AAK HYDRAULIC VALVE to try. When we received the hydraulic pressure valve drawing from Kate, we first gave a quotation. She told us very frankly that the price of AAK was 20% higher than that of other China hydraulic valve manufacturers, but 15% cheaper than that of the United States. She needed us to reduce the price greatly. We suggested providing the hydraulic pressure valve samples for testing first, and then discuss the price after passing the test. 2 weeks later, Kate informed that the test was qualified and AAK hydraulic pressure valve durability test had reached more than 40,000 times. She was surprised why AAK passed the hydraulic pressure valve durability test, while the other hydraulic valve manufacturers in China failed. AAK hydraulic valve was also eliminated by customers 2 years ago because the durability test of hydraulic pressure valve failed to meet the standard. AAK has increased research and development on the sealing ring. After more than thousands of tests in half a year, AAK chose to use a special PU polyurethane rubber sealing ring from Japan to overcome this technical problem. Its wear resistance and high pressure resistance are far better than other rubber sealing rings. The vast majority of domestic hydraulic valve manufacturers use rubber sealing rings, and the maximum limit of their durability test is 20,000 times. Kate realized that AAK was technically different from the other domestic peers, and the price was cheaper than that of American hydraulic valve manufacturers. She happily chose the AAK hydraulic valve with the highest cost performance. AAK hydraulic valve has advantages only by comparison.

This week, we’d like to introduce a hydraulic solenoid cartridge valve equivalent to HydraForce SV16-21. It is a solenoid-operated, 2 way, normally open, poppet-type, screw-in hydraulic cartridge valve, designed to function as a load-holding or blocking valve in applications requiring low internal leakage. Last week, we received an inquiry from an American customer Andrew for 100 pcs of hydraulic solenoid cartridge valve SV16-21. As usual, we quoted one price for 10 pcs of test order, and another price for 100 pcs for his regular order. Surprisingly, Andrew said that if we can give a 10% discount, he will place the order for 100 pcs of SV16-21 directly. Few new customers place orders directly without testing samples. After communication, we learned that his friend introduced AAK to him and the friend already tested the manufacturing quality of AAK. Then we knew that he was introduced by our another American customer Richard, who ordered 500 pcs of SV16-21 last August. Previously, Andrew purchased this solenoid cartridge valve SV16-21 from another hydraulic cartridge valve manufacturer in Ningbo China, the price is 10% lower than AAK, but the quality is not stable as expected. One he knew that Richard is very satisfied with the quality of AAK hydraulic cartridge valves, he wanted to switch the order to AAK but wanted to get the same price as his old manufacturer. To appreciate his trust in AAK and the introduction of our old customer Richard, finally, we offered a 5% discount, which is very close to the price that we offered to Richard for 500 pcs qty.   AAK hydraulic solenoid cartridge valve E-SV16-21 two advantages: 1.

Ibeamaka is from a hydraulic equipment company in Pakistan, and has been in the hydraulic industry for 3 years. At the beginning of last year, their hydraulic packer was complained by customers. The leakage of the hydraulic cartridge directional control valve in the system caused the equipment to work weakly, which was caused by the wear of the valve spool end. The original manufacturer of the hydraulic cartridge directional control valve said that because the system was opened and closed frequently, even if the valve spool of the bearing steel was worn, it was inevitable, so the service life of the hydraulic cartridge directional control valve could only be within 1 year. The boss was not satisfied with the original manufacturer's after-sales guarantee of more than 9 months, and requested to change the manufacturer, and the service life of the hydraulic cartridge direction control valve should not be less than 18 months. 1 week later, only one hydraulic cartridge valve manufacturer was willing to sample, which made Ibeamaka more worried. Ibeamaka searched the website of AAK hydraulic valves on Google and noticed many customer cases about the service life of AAK hydraulic cartridge valves. He sent an email asking if AAK can customize the hydraulic cartridge direction control valve and the service life shall not be less than 18 months. According to his drawing of hydraulic cartridge directional control valve, he also specially reminded that the original manufacturer’s problem on the valve spool. I told him that the hydraulic cartridge directional control valve spool of the original manufacturer was probably deformed after heat treatment, showing warping at both ends. During finishing, the end protective layer was removed, which affected the wear life of the valve spool. 5 years ago, AAK learned a similar lesson and has already upgraded the process. The valve spool is free of wear and has a service life of more than 18 months. Ibeamaka quickly sent an order for 120 hydraulic cartridge directional control valves. Last week, Ibeamaka sent an email. The hydraulic packers that used AAK hydraulic cartridge direction control valves had been working for 18 months. There was no complaint about the leakage of the hydraulic cartridge directional control valves. The boss was very satisfied. AAK hydraulic cartridge directional control valve spool is wear-resistant and durable, and its service life is twice that of the original manufacturer. It is due to the optimization of the process and 3 tricks in the processing process: 1. The spool of the hydraulic cartridge directional control valve is provided with a longitudinal main body of several bosses and two end faces at intervals. The included angle between the transition surface between the end of the valve spool and the adjacent boss and the axial direction of the valve spool is 5 degrees. This processing is particular, and most hydraulic cartridge valve manufacturers cannot control the accuracy. 2. The surface treatment layer of the hydraulic cartridge directional control valve spool forms a rotary machined surface. 3. The valve spool is easy to deform during processing. On the premise of ensuring the overall size of the valve spool, AAK adopts rotary reducing material processing, which can effectively retain the surface treatment layer at the end of the valve spool, and is more resistant to wear and corrosion, with a service life of 18 months. AAK hydraulic cartridge direction control valve has unique skills for processing, and its service life is twice that of its peers.

AAK hydraulic valve block adopts multi edge particle cutting with diamond reamer, the accuracy can reach 0.002mm, and the surface roughness can reach Ra 0.2um, the precision is twice that of other hydraulic valve manufacturers, and there is no iron filings. Because the price of AAK hydraulic valve block is a little higher than that of peers, LIEBHERR excluded AAK from the supplier list. However, 3 months later, LIEBHERR still placed an order for the hydraulic valve block with AAK. This morning, I received an order for hydraulic valve block from Herta from LIEBHERR company in Germany, which was a little unexpected. Because this is the hydraulic valve block that AAK sent sample for 3 months ago. Since the sample was sent, there was no news about the sample. After several follow up emails, the reply was "unqualified". I asked about the reason why the hydraulic valve block was unqualified, but didn't get reply. Now I can't understand why the order comes to us 3 months later. Herta is mainly responsible for the procurement of hydraulic accessories of LIEBHERR. In the first half of this year, his company needed to purchase a batch of high-precision hydraulic valve blocks for hydraulic excavators. At that time, he selected 5 hydraulic valve factories to send samples to test the quality and conduct assembly tests. 3 months later, after comprehensive comparison, their technical team found that the test data of AAK hydraulic valve block was the best among the 5 hydraulic valve manufacturers. I asked Herta curiously why the reply he gave us 3 months ago was "unqualified". He replied that your quotation was unqualified and more expensive than the other 4 hydraulic valve manufacturers, so we judged AAK to be unqualified. After 3 months of testing, the technical team believes that AAK's hydraulic valve block has the highest precision, the strongest durability and the simplest follow-up maintenance. Although the price of AAK is a little higher than that of other suppliers, according to the comparison of various parameters, the hydraulic valve block of AAK can enable LIEBHERR to reduce the cost of subsequent maintenance, so the technical department designated AAK to supply this hydraulic valve block. Herta asked us why some parameters of AAK hydraulic valve block are twice better than those of peers? The high precision of AAK hydraulic valve block mainly comes from the diamond reamer used in AAK machining center, which is a multi edge particle cutting. In the reaming process, the chips are hidden between the diamond particles and thrown out via coolant flushing and high- speed rotation, so that the chip removal in the first step is complete. Herta said that the accuracy of AAK's hydraulic valve block is 0.002mm, while that of the other 4 hydraulic valve manufacturers are all 0.004mm or above, and the surface roughness of AAK hydraulic valve block can reach Ra 0 2um, and the processing diameters of the holes tend to be the same, which is why their technical team is convinced. AAK hydraulic valve block has 3 advantages. You will know it after 3 months of trial. You are welcome to try the order. https://www.aakindustry.com/info-det , ail/hydraulic-valve-block-aak120

Chavan, from India, recognized the manufacturing quality of AAK hydraulic cartridge valve, but did not quite agree with the price of AAK hydraulic cartridge valve. He always thought that the hydraulic cartridge valve in China was cheaper than that in India. He came to me only for the hydraulic cartridge valve that India could not handle. A few days ago, Chavan sent an email to us, it was a list of hydraulic cartridge valves of SUN and HydraForce, and needed us to give him an advantageous discount price. The reason is that China's foreign trade has declined and manufacturers are more hungry for orders. In fact, I have defined Chavan as a poor customer who can't afford to buy, so I didn't offer a price and replied directly: I have no ability to give discounts, but I have the ability to deliver high-quality hydraulic cartridge valves. Since re-open from CNY holiday, the foreign trade orders were obviously reduced. The 18 countries in Asia collectively declined by 20%, the ASEAN declined by 12%, of which the Chinese Mainland declined by 25.5%, and Taiwan declined by 28.5%. It can be seen from this that not a single country's foreign trade situation is severe. In fact, I don't like to discuss the macro economy because 99% of the global enterprises are small enterprises and 99% of the global bosses are small ones. Therefore, it is more universal to discuss small businesses or small bosses. The hydraulic cartridge valve capacity of AAK factory is not even a dime in the whole hydraulic cartridge valve industry in the world. Therefore, the macro economy has nothing to do with AAK hydraulic cartridge valve. It is important to establish this concept, or belief, which may determine the trend of a factory. Well, even if the macro economy is poor, and 80% of the factories in the global hydraulic cartridge valve industry have closed down: 1）Why can't AAK hydraulic cartridge valve be one of the remaining 20%? 2）Why can't AAK hydraulic cartridge valve become Top 1% in 20%? 3）Why can't AAK hydraulic cartridge valve be one of the factories with differentiation and original technology? I prefer to discuss the micro and specific aspects. A manufacturing industry, a manufacturing hydraulic cartridge valve enterprise, even if the entire hydraulic cartridge valve industry is difficult to make money, why should we finally draw the conclusion that "I will definitely not make money, or I will definitely close"? Can't you do well? Think about it, you have worked in this industry for so long, why can't you make a top 1% of the market that can't be subdivided more? This is not very difficult. Finally, I want to say that don't understand the world with your own understanding of the world. Everyone's business situation is not very good, which doesn't mean you can't do it well. On the contrary, I have to think of ways to do better than 80% of my peers. At least let AAK hydraulic cartridge valve have a good life. There are inquiries every day, orders every week, innovations every month, and progress every year. What do you think is the main reason why a person has worked in his own industry for many years, or more than 10 years, but has not been able to be anything? The answer is only one word: lazy. Once one person is lazy, diligence, training and dreams are all gone. All day long, you can only muddle through for a few years, 10 years, and decades, but you haven't become a top muddle. For muddle, there is also a realm. If you have not been anything in your whole life, you will be in vain. AAK hydraulic cartridge valve, makes a little progress every day, only a little, and has become Top 1% of 20% of the hydraulic cartridge valve industry. https://www.aakindustry.com/info- , detail/cartridge-valves-aak521

Early last month, I saw an email from Mark, the purchasing manager of hydraulic system of Caterpillar, an old friend of ours. The subject of the email is "I need help from AAK, I believe". After reading the email about hydraulic threaded cartridge valve, I understood Mark's embarrassment. A small less-known excavator designed by them at the beginning of this year was not smooth in the commissioning process, the response of the excavation part was slow and the power was not enough. After testing, the technical department found that the measured value of the maximum overflow pressure was lower than the specified value, so it was determined that there was a problem with the hydraulic threaded cartridge valve. Mark communicated with the original hydraulic valve supplier. The supplier mentioned that the hydraulic threaded cartridge valve was sampled according to their company's drawings, and all parameter tests were up to standard. The supplier told the fact. He then could only patiently communicate with the design department to see how to modify the hydraulic threaded cartridge valve design, but the design Department said that there was a problem with the installation of the technical team. The company's design and technology departments prevaricate with each other and Mark are caught in the middle, which is very embarrassing and time is also being wasted. If the boss is angry one day, it is estimated that all 3 parties will be criticized. AAK HYDRAULIC VALVE has always been Mark's most trusted supplier of hydraulic valves. I asked Mark to send us the original design drawings of the hydraulic threaded cartridge valve and the working condition requirements of existing equipment, as well as the problems and data encountered in commissioning. 3 days later, we replied to Mark that we have a new design scheme, and we are 90% sure that we can make the hydraulic threaded cartridge valve that meet the equipment requirements, but it will take 2-3 weeks. On the 3rd day after receiving our sample of the hydraulic threaded cartridge valve, Mark happily informed us that the technical department tested AAK hydraulic threaded cartridge valve, the equipment commissioning was smooth, and the reaction and power of the excavation part were normal. The technical department said that the large goods of this hydraulic threaded cartridge valve can only come from AAK, and other hydraulic valve manufacturers are unreliable. Caterpillar designers are also curious about how AAK HYDRAULIC VALVE redesigns this hydraulic threaded cartridge valve? AAK engineering team tried 30 times to design, sampling and make adjustment to find a breakthrough. A sealing ring groove is arranged between the oil replenishment outlet and the oil replenishment inlet of the oil replenishment valve seat of the hydraulic threaded cartridge valve. The oil replenishment valve seat is made into a cartridge valve body, a sealing ring is installed between the overflow valve seat and the rear end hole of the oil replenishment valve spool, and a spring with a set oil replenishment pressure difference is placed. For the hydraulic threaded cartridge valve with this structure, the excessive pressure oil can directly push the overflow valve spool from the oil replenishment outlet and automatically relieve the pressure. The whole overflow action is more direct and sensitive than before, and the pressure regulation response is fast, which protects the whole pressure system and the pressure is more stable. After knowing the whole process, the boss praised mark, rewarded him with an extra week's holiday, and suggested him to increase cooperation with AAK HYDRAULIC VALVE. His colleagues in the technical department and design department also admire him for taking the initiative to solve the dilemma of the hydraulic threaded cartridge valve, and Mark's prestige in the company is getting higher and higher. AAK is a designated hydraulic threaded cartridge valve manufacturer of Caterpillar. You can also have a small try. https://www.aakindustry.com/info-detai , l/hydraulic-cartridge-valve-aak121

This week, we launched a hydraulic cartridge needle valve benchmark SUN NCEB standard parts. This hydraulic needle valve is with reverse-flow check are fully adjustable orifices used to regulate flow. They are infinitely adjustable from fully closed up to the maximum orifice diameter. An integral high-capacity check valve provides unrestricted flow from port 2 to port 1. They are not pressure compensated. Because needle valves are non-compensating devices, the fixed orifice size will regulate flow through the valve in proportion to the square root of the pressure differential across ports 1 and 2. For this valve, we have full 5 options: NCEB-LCN, NCEB-LAN, NCEB-LEN, NCEB-LBN, NCEB-LDN. In 2022, a German customer ordered NCEB-LCN from AAK for 3 times. AAK hydraulic needle valve 2 major advantages: 1. Manufacturing quality, function and performance benchmark SUN. 2. But the price is less than 70% of SUN. Technical parameters of AAK E-NCEB Hydraulic Needle Valve: Maximum Operating Pressure: 350 bar (5000 psi) Capacity: 12 gpm (48L/min) Internal Leakage: 10 drops/min. Cavity: T-5A AAK hydraulic check valve, 3 key elements benchmark SUN NCEB, you can also give it a try.

For young people, having a life mentor can help us avoid many detours. For hydraulic manifold manufacturers, if they can have a mentor like customer, then hydraulic manifold manufacturers will grow rapidly. Hydraulic manifold manufacturer AAK, 10 years ago, with the guidance and requirements of Honeywell, have grown into a Top 3 hydraulic manifold manufacturer in the Ningbo region. A considerable number of people, or hydraulic manifold manufacturers, say that life mentors are something that can be met but not sought after, believing that encountering them is a form of luck. But hydraulic manifold manufacturer AAK believes that: in fact, we often encounter life mentors, but you do not receive instruction, so those who could have become our life mentors are far away from you. So what is' not receive instruction'? The hydraulic manifold manufacturer AAK understands it this way. For example, Jack wants to buy an apartment that is small in size, low in price, and close to the subway. Jack was unsure, so his friend suggested that he ask their classmate Mr. Li (the owner of a real estate company). Mr. Li's suggestion: The entire real estate industry is on a downward trend, and it is not recommended to buy an apartment at this stage as it will be difficult to sell in the future. If Jack receives instruction, his response is: Okay, listen to you! I won't consider it anymore. I was still hesitant, thank you. This kind of response will make Mr. Li feel very comfortable. You are very "educated", and if you have any confusion about the property next time, he is willing to give you guidance. If Jack does not receive instruction, his response is: I think what you said makes sense, and I also think so, so I won't buy it. Obviously, you came to consult Mr. Li, but your reaction made everyone feel that you were discussing issues with Mr. Li and also commenting on the conclusions given by others. Since you understand everything yourself, why do you come to ask others? The decision not to buy in the end seems to be based on your own analysis, and others' opinions are only for reference. To put it bluntly, you just don't want to be appreciated. There are also many similar scenarios in the daily email discussions between hydraulic manifold manufacturers and customers. Clearly, it was the hydraulic manifold manufacturer who asked for an idea from the customer, but the result was a 'I also think so'. Customers have strict requirements for hydraulic manifold manufacturers, but they think it difficult to serve customers. Before, I have also mentioned the relationship between hydraulic manifold manufacturers and customers, just like teacher-student relationships. But teachers and students achieve each other, and without good students, there is no good teacher. Perhaps the story of Jack above is difficult to understand. If you read it multiple times based on your own life experience, it may be enlightening. In life, you should hold a humble attitude, with friends and teachers around you, so that your path will become smoother and smoother. Similarly, hydraulic manifold manufacturers need to maintain an open and studious attitude, with not only customers but also mentors around them. Only then can the path of hydraulic manifold manufacturers become smoother and smoother. Hydraulic manifold manufacturer AAK in Ningbo China, is open, pragmatic, and studious.

At the beginning of last month, Berton sent an email to us, with the theme of "damn hydraulic valve block", which surprised me. I thought there was something wrong with the hydraulic valve block purchased by Berton from AAK. After reading the email, I learned that he purchased the hydraulic valve block from a German company. There was a leakage problem in the two proofing, and each time the sampling modifying process was very slow, which affected the commissioning of the whole equipment. The technical team had complained to the boss, who was a little annoyed and asked him to get the modified sample of the hydraulic valve block approved for the third time within 1 month. The German factory advised that the third hydraulic valve block sample could be solved at one time, but 1 month was not enough, which made Berton very helpless. Because this series of hydraulic valve blocks has been purchased in Germany before, Berton has to wait for the revised sample from the German factory, and find a new hydraulic valve block supplier at the same time. He wanted to check if AAK has any good suggestions. I asked him to send the hydraulic valve block design drawings to us, note the working conditions, and also send the second unconfirmed hydraulic valve block samples to AAK for comparison. According to Berton's drawings and the samples of the hydraulic valve block from the German factory, the finished product quality is good and worthy of being produced by the German factory. The root cause of the leakage is that the perpendicularity tolerance between the thread of the hydraulic valve block and its mating surface reaches 0.08mm, which should not be higher than 0.05mm according to the working conditions. This tolerance dimension is difficult to control and has high requirements for the operator, We recommend changing the system design of the hydraulic valve block. If it is successful, samples of hydraulic valve blocks can be sent within 25 days. Berton has no better choice but to wait passively. 5 days after sending the sample, Berton was excited to inform that the sample of AAK's newly designed hydraulic valve block met the system requirements of the equipment and did not leak. The accuracy and efficiency of the hydraulic valve block were both improved compared with the hydraulic valve block of the German factory. Berton is curious about why AAK dares to change the design of the German factory. Even the engineers of his technical team admire the new design of AAK hydraulic valve block. Based on the design of the German factory, AAK changed the whole oil circuit design. Some valve holes can be combined with the same unit to perform a specific type of control function, which is conducive to improving the execution efficiency of the hydraulic power system. At the same time, the pressure regulation loop, flow control loop and power supply loop are newly designed. The reason why AAK dares to make such changes is that we have an efficient machining center, MIKRON machining center and AMEC sinking drilling and milling cutter. This combined cutter can directly complete the processing of the dimensional accuracy required by the diameter of the threaded bottom hole and the sealing ring, and also the processing of the surface finish. Moreover, it has central internal cooling and allows faster cutting. In this way, man-made errors are eliminated in accuracy. Berton said happily that he could finally ignore the arrogance of the German factory. The boss asked him to transfer the order directly to AAK, and the price was cheaper than that of the Germany factory. The boss was very satisfied with Berton's idea of finding a new supplier of hydraulic valve blocks. AAK can not only make high-precision hydraulic valve blocks, including different types of hydraulic valves, but also help you with design solutions. You can try a small order. https://www.aakindustry.com/info-det , ail/hydraulic-valve-block-aak119

Yesterday, I received a repeat order for a hydraulic sequence valve from Gary. The first order of this hydraulic sequence valve was placed 3 years ago. Before, I wondered why this hydraulic sequence valve had not been repurchased, thinking that it had been switched back to the United States for production. I really didn't expect to receive the repeat order after 3 years, and the quantity was more than 3 times that before. 3 years ago, Gary’s company had a newly designed hydraulic pump to be produced in Vietnam branch, and the pump needed hydraulic sequence valve. If purchasing the hydraulic sequence valve in the United States and delivering it to Vietnam, it was expected to take 3 months or more. His boss wanted to try purchasing in China, hoping to save half the time. According to the boss's instructions, Gary spent 3 days looking for hydraulic valve factories, selected 5 hydraulic valve manufacturers from more than 10 as their hydraulic sequence valve suppliers, and asked them to send reference samples of hydraulic sequence valves to Vietnam for testing. Gary happily reported the purchasing status to his boss, who was satisfied. After Gary received these hydraulic sequence valve samples, he arranged the technical department to match the working conditions for testing, but the results were poor. The matching clearance between the valve body and the valve spool of some hydraulic sequence valves was small. After an additional 20% pressurization, the valve hole was deformed and the valve spool would be stuck. All 5 hydraulic valve manufacturers said that after additional pressurization, they were not able to ensure the quality of hydraulic sequence valve. Time has been wasted for more than 2 weeks. At this time, if returning back to the United States to purchase hydraulic sequence valves, he would be scolded by his boss. Gary began to worry. When Gary browsed AAK website (www.aakindustry. com), he felt that AAK hydraulic valve was some different from the other hydraulic valve manufacturers. He emailed to inquire about the hydraulic sequence valve and frankly told us the problems he had encountered with Chinese hydraulic valve manufacturers. After several rounds of e-mail communication and AAK technical team's analysis of his drawings, we truthfully told him that AAK's existing hydraulic sequence valve samples could not meet his pressurization test. It takes 2 weeks to proofing according to the drawing. If the sample of the hydraulic sequence valve is approved and it takes 25-30 days to produce his order for the hydraulic sequence valve, Gary calculates the time. If the sample of AAK's hydraulic sequence valve is successful, the time saving meets the requirements of the boss. If it is not successful, it will waste another 2 weeks. It seems that he has no choice. Somehow, Gary feels that AAK can give him hope and hopes that we can send samples as soon as possible. 4 days after the samples of the hydraulic sequence valve were sent, Gary e- mailed to us that the pressurization test passed. The problems happened on the samples of the previous 5 hydraulic valve manufacturers are now gone. At the same time, all the parameters of AAK hydraulic sequence valve can be compared with those produced in the United States. Gary asked us to hurry up to prepare for production and deliver on schedule. In order to avoid pressure deformation, AAK adjusted the production process of the valve hole and applied the technical method of "avoiding deformation" to the production process of the valve hole. An experienced AAK technician who had operated for 7 years failed for 3 times before mastering this operation key point. After Gary knew this, he said it slowly that only at this time, he really knew the difference of AAK hydraulic valve and didn't want to waste time looking for homogeneous hydraulic valve manufacturers. AAK hydraulic sequence valve is benchmarked with the original American hydraulic valve supplier, and has become the only hydraulic valve supplier of a Russian customer. You may not be able to find a second one like AAK in Ningbo. You can also have a small try. https://www.aakindustry.com/info-detail/hy , draulic-sequence-valve-aak118

Diego, from Spain, has been engaged in the procurement of hydraulic valves for 5 - 6 years, and has been successful. But the hydraulic cartridge needle valves purchased from a local manufacturer stumped him. At the beginning of last year, their company urgently purchased a batch of hydraulic needle valves to be installed on a batch of hydraulic equipment that customers urgently need. Diego purchased the hydraulic needle valves from a local manufacturer. 3 months after the equipment was sold, the customer complained that the equipment was unstable. After testing the hydraulic system, it was found that when the hydraulic needle valve spool was in the fully closed position, it was stuck radially, because the coaxiality deviation between the valve spool and the valve body was 2μm, 3μm, or 4μm. That is, the standard deviation is not up to standard. The original manufacturer of the hydraulic needle valves advised that this is an individual and can be replaced, but there are more and more complaints later. Diego knows that the coaxiality deviation must be completely solved. After discussion with engineers, Diego defined the coaxiality accuracy of hydraulic needle valve spool and valve body within 2μm. Based on this quantification, Diego contacted more than 10 hydraulic needle valve manufacturers, but none of them offered quote for a week. The customer is pushing the after-sales service process. Now there is no solution. Diego is under great pressure. Diego found AAK on Google, noticed that AAK had solved the coaxiality problem for customers, and left a message to us: Can you control the coaxiality error of the hydraulic needle valve within 2μm? At the sight of such messages, it was assumed that he had encountered difficulties in purchasing hydraulic needle valves. After communication, it was learned that even he purchased from Spain hydraulic valve manufacturer, coaxiality deviation could not be completely avoided. When he learned that HydraForce has been a loyal customer of AAK for 9 consecutive years, AAK hydraulic valves have also served 3 Fortune 500 enterprises, and there are customer cases that coaxiality problem has solved, he asked about the development time and cost, which means he wanted to try the order. I always think that in the field of industrial products, customers do not buy your products, not because of distance or high prices, but because they do not trust you. 50 days later, AAK sent 30 hydraulic needle valve samples. 4 weeks later, Diego informed that AAK hydraulic throttle valves had been installed on the equipment and the overall operation was normal. I replied that within 18 months, there was no after-sales concern. Last week, Diego said in an email that the AAK hydraulic needle valves have been installed in the equipment for more than a year, and there is no customer feedback on what function is affected by the coaxiality. The coaxiality error of AAK hydraulic throttle valve is controlled within 2μm, and lead the industry with 3 aspects: 1. The valve spool and valve hole of the hydraulic needle valve are finely machined.

Francis is from a hydraulic equipment company in Spain, and has been purchasing smoothly for 5 years. Some time ago, he was stumped by a hydraulic cartridge proportional relief valve. The hydraulic cartridge proportional relief valve used in their customized hydraulic power unit was made by a local cartridge valve manufacturer. The equipment commissioning was not smooth, and the hydraulic cartridge proportional relief valve responded slowly and leaked when the system was in a large flow state. The original manufacturer tested the accuracy of the hydraulic cartridge proportional relief valve, and all of them reached the standard. The engineer asked the original manufacturer to optimize the structure of the hydraulic cartridge proportional relief valve, but no result after 1 week. Francis contacted several other hydraulic cartridge proportional relief valve manufacturers, but there was still no solution. Francis was worried. Francis noticed AAK hydraulic valve in B2B and left us a message: 1. The hydraulic cartridge proportional relief valve responds slowly, and there is a source of leakage? 2. Can AAK optimize the structure of the hydraulic cartridge proportional relief valve? 3. What is the cost and lead time of customized hydraulic cartridge proportional relief valve? After communication, we learned the situation that Francis purchased the hydraulic cartridge proportional relief valves. According to the drawings of the original hydraulic cartridge proportional relief valve, the samples of the original manufacturer, and the requirements of equipment working conditions, AAK engineers judged that the problem was probably caused by structural hazards, and AAK was 90% sure to optimize the original structure. Francis asked for AAK samples. After 45 days, AAK sent 12 samples of hydraulic cartridge proportional relief valves. 1 month later, Francis informed us by email that with AAK hydraulic cartridge proportional relief valve, the trial run of the equipment was smooth, and the customer was satisfied and planned to place a large order. Francis asked us to wait for the good news. AAK hydraulic cartridge proportional relief valve can realize large flow rate, fast response speed and no leakage. For these 3 advantages, we have made 3 optimizations on the structure: 1. The valve body of the hydraulic cartridge proportional relief valve is provided with a stepped inner hole. The side wall is provided with a stepped port. The valve cage is connected to the lower part of the valve body. On the side wall of the lower part of the valve cage, there is a flow passage cavity between the valve body and the valve body. The upper part and the inner hole of the valve body form an oil return cavity and a flow passage hole. 2. One end of the valve spool of the hydraulic cartridge proportional relief valve is slidably arranged in the inner hole of the valve cage, which can control the on-off of the through flow hole. In the oil return chamber, the lower part of the spring is against the upper part of the valve spool, and the upper part forms a control chamber with the valve body. The force on the valve spool can be changed according to the pressure of the control chamber. 3. The valve body of the hydraulic cartridge proportional relief valve is also equipped with an electric proportional control system. Its oil inlet is connected to the flow passage chamber, and its oil outlet is connected to the oil return chamber. The pressure of the control chamber is changed by changing the voltage control signal of the electric proportional control system. The optimized hydraulic cartridge proportional relief valve uses a small flow electric proportional control system to change the pressure of the control chamber, set the pressure of the spring assembly, realize the large diameter setting of the valve port, increase the flow capacity, and have a fast response speed. The valve is line sealed and has no leakage. AAK hydraulic cartridge proportional relief valve, has 3 advantages, with large flow, fast response and no leakage, you can also try one small order! https://www.aakindustry.com/info-det , ail/relief-valves-aak446

The customer from Brazil said that due to domestic political reasons, his purchase from Chinese hydraulic cartridge valve manufacturers has been held, but promised to come to me as soon as there is an inquiry for hydraulic cartridge valve. The customer from Turkey said that due to the impact of the huge earthquake, the purchase of hydraulic cartridge valves from Chinese manufacturers has decreased a lot, but it is estimated that the normal situation will be restored in 2 months. Although these 2 markets are very important to Chinese hydraulic cartridge valve manufacturers, AAK also has inquiries from customers in the United States, Canada, South America and Europe. I do 3 things every day: read more, work more and learn more. Working and learning are my 2 sources of motivation, and the only reason why AAK stands out from Chinese hydraulic cartridge valve manufacturers. Some people like to see practical information very much. These Chinese hydraulic cartridge valve manufacturers in Ningbo also want me to share it. In fact, no matter how good other people share practical information, if you see it but will not really do it, at most, you will be touched at that time, and everything will return to the original state after 60 seconds. This is the truth of the brain, not your intention. Of course, what is slightly better than practical information is the professional books related to Chinese hydraulic cartridge valve manufacturers, but this also varies from person to person. My motivation for learning and practice comes from 2 aspects: 1. A strong spiritual awareness to change the Chinese hydraulic cartridge valve manufacturer. Of course, the Chinese hydraulic cartridge valve manufacturer here refers to AAK, not other Chinese hydraulic cartridge valve manufacturers. 2. The book has taught me how to do well in the production of hydraulic cartridge valves and how to earn money from hydraulic cartridge valves. With the support of these 2 things, I will have the strength to learn and work specifically. As for the practical information on the Internet, they will play a role of 2% at most. Take a look at your online collection. Maybe you have collected a lot, or you don't even look at it. This action is a psychological placebo. The only reason why we can continue to work is the sense of achievement. For example, there are inquiries from customers every day and orders every week, and why customers choose AAK from so many Chinese hydraulic cartridge valve manufacturers In fact, many times, it is useless to only know and understand. You can easily buy a copy of the Working Principles of Hydraulic Cartridge Valves, but it is difficult to produce hydraulic cartridge valves. If I can't make a result, it's worse than I don't understand and don't know. Because you have the knowledge to compete with the peers of Chinese hydraulic cartridge valve manufacturers everywhere, and the results of the competition, you can't find a place among the peers of Chinese hydraulic cartridge valve manufacturers. I, a small boss in the hydraulic cartridge valve manufacturing industry, write 7 tweets a week, each of which is a customer case. Solve a specific problem of hydraulic cartridge valve innovation, or manufacturing quality, or optimization, or customization, as well as various difficulties and complications in the production process of Chinese hydraulic cartridge valve manufacturers. Each tweet will be posted in 30 B2Bs every day. Not long after I started to write the tweet, I found that the peer of the hydraulic cartridge valve manufacturers in China was copying. I saw it, but kept quiet. Later he continued to copy. I continued to write, but after a period of time, I didn't see him copy it. Then until now, he sometimes asks AAK to produce the hydraulic cartridge valve he couldn't handle. At that time, my colleague asked me: What should we do? The peer of Chinese hydraulic cartridge valve manufacturer is copying us. My answer: Only when it is valuable can it be copied by the peers of Chinese hydraulic cartridge valve manufacturers. I'm not afraid of copying, so I don't care about his copying. In this way, under the shock of my saturation, the peer of Chinese hydraulic cartridge valve manufacturer not only “lay flat”, but also gave me orders for hydraulic cartridge valves that he is not able to produce. I need to write tweets every day. I completely forget the word "persistence". Even if you inspire yourself every day, it's useless, and you can't persist. Where is the key? There should be a sense of achievement, even a small sense of achievement, such as customer inquiries. If there is no sense of achievement, then even the immortals cannot persist. Adherence is anti-human and should be supported by a sense of achievement. The peers of Chinese hydraulic cartridge valve manufacturers sell on the ground, and AAK will do online sales. I jokingly call this a dimensional reduction attack. If the peers of Chinese hydraulic cartridge valve manufacturers are also online, AAK will do it every day. I jokingly call it a saturation attack. Let Chinese hydraulic cartridge valve manufacturers despair, give up imitation, give up plagiarism, and “lie flat”. AAK hydraulic cartridge valve, has no peer. https://www.aakindustry.com/info-deta , il/cartridge-valve-manufacturer-aak520

Last week, hydraulic manifold manufacturer AAK wanted to hire an engineer to do sales. The young man had worked as an engineer in other hydraulic manifold manufacturers for 3 years, and when he met me, he said the first sentence: I don't have anything, can sales of hydraulic manifolds be successful? What is behind this problem? Actually, can I get something for nothing? What should I do to get something for nothing? I really want to work as a salesperson at hydraulic manifold manufacturer AAK, but I always feel like I have no ability or talent. This type of question is equivalent to saying, 'I don't have core competitiveness, but I also want results.'. For example, most hydraulic manifold manufacturers only know how to copy, but they want orders. So I want to say, why? This world is not interesting at all, there is no overnight wealth, nor is there a counterattack. The overnight fame you see is behind everything you cannot see, the accumulation of night and night. To become better, one can only squat solidly every day, step on plum blossom stakes, and establish their true core competitiveness. There is no shortcut for hydraulic manifold manufacturers. The truly difficult thing is day after day. Someone always wants to become rich overnight and find the secret to winning with one move, because it is so rough, fast, and direct. Life is more than one choice, more than one battle. We have also seen many cases of rapid death after consuming stimulants. For hydraulic manifold manufacturers, if they really want to succeed, they can ask "How can I establish my own core competitiveness and increase my chances of success?” Hydraulic manifold manufacturer AAK posts tweets or videos on its website every day, but some colleagues complain that this path is too difficult. Is there an easier one? The hydraulic manifold industry is too complicated and laborious. Would it be easier for the neighboring industry? Such complaints are like saying, 'Where do I go without putting in too much effort?'? Like most hydraulic manifold manufacturers saying,” where can I make easier profits?” To be honest, there are, but very few. In all walks of life, what should be difficult is difficult. Don't think others are "easy" just because you work hard. Because the so-called 'easy' is often only in the hands of a few people. Don't ask, 'This road is too difficult, is there an easier way?'. If hydraulic manifold manufacturers really want to find an easy path, they should ask, "Have there been any changes in the hydraulic manifold industry recently? Are there new emerging technologies, and have we actively followed up?” Some hydraulic manifold manufacturers' sales sometimes complain that this customer is too difficult to handle. “What should we do? This hydraulic manifold is really stable, and engineers feel that it far surpasses their competitors in the market. That customer is pushing the price down very hard. Alas, the current customers are really getting harder to serve. Such a good thing is really not expensive.” This type of problem is equivalent to saying that I have done it well enough and the customer is not aware of the goods. Hydraulic manifold manufacturer AAK wants to say: don't think that way. If you haven't found the wrong customer, they think the price is expensive, and there are often only two reasons. Firstly, he believes that this hydraulic manifold is not worth spending so much money on. Secondly, the hydraulic manifold may cost him so much money, but your hydraulic manifold is not worth it. As long as customer think that it's not worth it, it's really not worth it. The only solution is to provide enough value to make him feel truly worthy from the bottom of his heart! If the hydraulic manifold manufacturer really wants to solve the problem, ask "What kind of value should I provide in order to make customers feel that it is truly worth it.” In recent years, those stable and precise channels have gradually disappeared. Dividends turn red sea, profits become thinner, and competition becomes increasingly fierce. The more we reach this point, the more we actually have to do more difficult things and take more difficult paths. The easier road you take, the narrower it becomes. The more difficult the road is, the wider it becomes. Hydraulic manifold manufacturer AAK, with more real thinking and less fake problems.
