Today is Sunday and I woke up earlier than usual. I woke up at 4:00 and was alone in my study imagining the future of China hydraulic solenoid valve manufacturers. However, it seems that I can't calm down. Alibaba's layoffs are still in my mind. Is Alibaba's layoffs related to China hydraulic solenoid valve manufacturer AAK? Alibaba's massive layoffs have caught the attention of many people these days. During 3 years of the pandemic, there have been no layoffs, they have resisted but are now starting to lay off employees. After rolling up sleeves and working for 6 months, they realized that the arms were really cold outside. It's cold even in summer, how cold it will be in winter. Alibaba's layoffs are a step towards reducing costs, and a further step towards entering the era of meager profits for the internet. The further step is to prepare for a lasting war. The first ones to be cut are all P7, P8, and P9, and the HR of the big company is skilled. Objectively and calmly, the halo of the internet's frequent annual salary of millions is built on the dividends of the times. China hydraulic solenoid valve manufacturer, AAK, although working hard, at least do not feel cold. I know that it is important to deeply cultivate an industry, especially in the industrial sector. For example, for China hydraulic solenoid valve manufacturers, the competition is the boss's understanding, workshop manufacturing quality, and your customer base, especially high-quality customers. For example, AAK has Honeywell, a Fortune 500 company, and the industry leading companies HydraForce, SUN Hydraulics. It is difficult for China hydraulic solenoid valve manufacturers to have such gains or recognition if without rooted in the industry for more than 10 years. The world's giants are changing, and the China hydraulic solenoid valve manufacturer AAK also needs to change. Personally, I need to have more changes. Change is an upward ladder. This is the important change we are facing in 2023. Opportunities are hidden in change. OpenAI, launched ChatGPT that everyone is discussing; Elon Musk plans to spend $10 trillion to transform the Earth's Master Plan; Humans may have controllable nuclear fusion of "star energy"...... User psychology of solenoid valves, product trend of solenoid valves, process of solenoid valves, technology of solenoid valves, Change, change, change. In today's information age, almost everyone has "seen" these changes at the same time. I am not earlier than you, nor are you later than me. However, can we "understand" and become the core competitiveness. It will also widen the gap between each other. There are 2 ways to understand change: 1. Read more books. Every book can open up blind spots. The more you see, the more you think and understand. Standing on the 1st, 10th, and 100th floors has a completely different view. Read at least 20 books per year. For those with strong abilities, consider at least 50 books. 2. See more people. People are even more living books. Everyone has their own way of looking at problems and a dimension to think about the world. Entering a high-energy and high-density circle and field allows for access to more information and insights. Other people's words may be my enlightenment. Prospective cognition is hidden in the best and brightest people, to understand the changing world through their eyes, to hear the sound of change through their ears, to judge the opportunities for change through their brains. Read more books and meet more people. I wrote these 6 words on the homepage of my notebook 3 times. As a China hydraulic solenoid valve manufacturer, to meet with more high-quality solenoid valve customers on the road to change, is the 2023 Key target of AAK.

Merchant is from Brazil. In the second half of last year, they developed a hydraulic power unit, which requires a hydraulic cartridge directional control valve and has a durability of more than 2 million times. Considering the development lead time, Merchant decided to select the manufacturer of hydraulic cartridge directional control valve from Brazil. One week later, all manufacturers could not guarantee the durability of 2 million times. Only one manufacturer accepted the trial order. 45 days later, the manufacturer still has not sent the samples, and Merchant was informed that the hydraulic cartridge directional control valve failed the internal test in the factory, so a new sample is needed, and the delivery date is difficult to determine. All the components required for the equipment are in place, except for the hydraulic cartridge directional control valve. The merchant was pushed by the engineer again and again. Merchant tried to contact the overseas hydraulic valve manufacturers for this hydraulic cartridge directional control valves. Because of the small quantity and high requirements, few manufacturer paid attention to Merchant. Merchant was embarrassed and worried until he met Nicholas, an old colleague, and let him see some hope. Nicholas sent me an email and CC Merchant, then I knew that Merchant had encountered difficulties in purchasing hydraulic cartridge directional control valves. Nicholas mentioned in his email that if AAK can't achieve the hydraulic cartridge directional control valve for 2 million times, then don't waste time in Ningbo. I think this is Nicholas's greatest trust in AAK. According to the drawing of hydraulic cartridge directional control valve sent by Merchant, it is not a big challenge. I told him that based on Nicholas's trust in AAK, I would arrange the workshop to start programming. Samples will be sent out within 5-6 weeks. Merchant immediately relaxed and paid for development fee. Two weeks after the AAK hydraulic cartridge directional control valve was sent, the Merchant emailed us that AAK hydraulic cartridge directional control valve help to test the machine smoothly, but the performance is a little worried. I told Merchant that the performance of AAK hydraulic cartridge directional control valve for 2 million times is not a slogan, but an existing fact. Otherwise, Nicholas would not introduce AAK to him, so that he could be relieved. Because AAK has 3 advantages in terms of performance: 1. In terms of material selection, the valve body of the hydraulic cartridge directional control valve is made of Japanese SCM415 alloy steel, and its mechanical properties are more than 70% stronger than those of similar materials. After carburizing and heat treatment, the hardness of the valve body is higher than HRC65, and the wear resistance is more than 3 times of the general 45 steel. Material selection is the key, heat treatment is the core, and most of the peers are not sufficient here. 2. In terms of machining, the valve hole of this hydraulic cartridge directional control valve is machined with diamond reamer, which is completely ground without trace, and the accuracy of the valve hole is guaranteed to be within 1.2μm, the surface roughness reaches Ra0.2-0.3. 3. In terms of technician, with 30 years of experience and 12 years of equipment operation, it is difficult for the operation to be with defects. There is no third one in Ningbo. AAK hydraulic cartridge directional control valve, with the performance of 2 million times, you can also have a small try! https://www.aakindustry.com/info-detai , l/hydraulic-cartridge-directional- control-valv , es-aak368

Taking the market share or taking orders, almost a lot of inertial thinking thinks that Chinese hydraulic valve manufacturers rely on price. No wonder, in the Fortune Global 500 list a few days ago, although there are 145 Chinese enterprises, their profits are only half of those of American enterprises. A few days ago, I saw a short story about Huawei. When meeting Ren Zhengfei, the chairman of a Fortune 500 company said, "How can Huawei succeed in the world by using low-cost tactics?" Ren Zhengfei blurted out: You are wrong. We do not rely on low prices, but on high prices. In the European market, Ericsson has the highest price. The average price of Huawei is 5% lower than Ericsson, but 5% - 8% higher than Alcatel, Lucent, Nokia and Siemens. It seems that when Chinese products sell well in the world, they must think that they occupy the market by low prices. What is the logic? The essence of business is transaction. Trade, take my value to exchange the other party's value. The reason why the business can grow is that the enterprise has more ability than the things to exchange. If the capacity overflows, it will grow. Why can enterprises grow and make money? Make the products more valuable and produce more products, so we can get more. AAK Hydraulic Valve can make the hydraulic valves more valuable. Perhaps the price is 20% more expensive than that of the peers, but the service life of the hydraulic valves is twice that of the peers. This is the capacity overflow of AAK. I think this is also the direction of Chinese hydraulic valve manufacturers. Chinese hydraulic valve manufacturers have the ability, then can exchange more thing. Whether the growth is fast or slow depends on whether the enterprise has a good strategy and high production efficiency. However, behind the growth of enterprises is the spillover of endogenous capabilities, and there must be a basic value. The value is that if the company wants to make money, it must take better value to exchange. Only with such values can we adhere to the long-term principle. AAK has been firmly committed to this road since it got the first trial order of HydraForce 10 years ago. The same is true of AAK people. If they want to become business experts, they should work hard on the professional skills of hydraulic valves to become engineers. A real business expert is indispensable for his mental strength, physical strength and intelligence. If you do one thing and focus on the next 3 years, there will be more peers. If we can focus on the next 7 years, the number of peers will decrease by at least 70%. Because few Chinese hydraulic valve manufacturers are willing to make such long-term plans. Long termists, calm down fluctuations, cross cycles and embrace trends. Long termism, rolling forward, for tomorrow. The price of the hydraulic valve can be seen by everyone. The value of the hydraulic valve can be perceived only when you trust it. AAK hydraulic valves have been exported to more than 20 countries. In fact, many buyers in Europe and America are reluctant to negotiate extra prices because they pay more attention to time cost. However, they require that the value of hydraulic valves must be better than the price, and they are willing to let Chinese hydraulic valve manufacturers earn reasonable profits. AAK can build mutual trust by using reasonable price and value superior to price. Good business people will not use those assistants who buy goods directly on the Internet without paying attention to the time cost. Building a good service relationship with people will be more successful businessmen, because they all use their time very efficiently. I always remember that the only thing about AAK is trust. In the 13 year history of AAK Hydraulic Valve, sometimes I am too tired to walk. Sometimes, my eyes are foggy. Sometimes, I also want to give up. Sometimes, at the crossroads in front of me and you, it not a choice between "right road" and "wrong road". The choice between right and wrong is not difficult. Most people will choose the “right road”. In front of us, there is usually a "right road" and an "easy road". The easy road is so attractive, comfortable and familiar. The right road is narrow, far and tortuous, and it takes a lot of time. Even, for a long time, there is no light. But if we stick to the long-term principle, all changes will be beneficial. Let you find a little certainty in the great uncertainty. AAK Hydraulic Valve has embarked on a difficult and right road, even if the road ahead is rough and thorny. But I believe that the hard road is never crowded. https://www.aakindustry.com/in , fo-detail/chinese-hydraulic-valve-manufacturers- aak367

Last weekend, Boris from Russia left a message on the website of hydraulic manifold manufacturer AAK: I have followed your article about valve hole accuracy 2μm for hydraulic manifolds. How does AAK do the precision machining? After communication, we learned that Boris is an engineer from a hydraulic manifold manufacturer in Russia, who also purchases from Chinese hydraulic manifold manufacturers. Although their supplier also has German Gehring high-precision CNC honing machines like AAK, there are still a small number of valve holes that do not meet the accuracy standards, which makes him very distressed. This is a very interesting message. Boris seems to be learning from hydraulic manifold manufacturer AAK and doesn't seem to believe it very much. I asked Boris if he knows how his supplier checks the accuracy of valve holes after precision machining. I sent him a video of AAK valve hole accuracy testing. 3 days later, Boris replied that his original supplier did not have such testing equipment. Today, I received his inquiry for a hydraulic manifold, the valve hole accuracy needs to be controlled within 2μm and with a verticality tolerance controlled within 5 microns, this may be an appetizer for Boris testing hydraulic manifold manufacturer AAK. I am very confident in winning a high- quality hydraulic manifold customer. How does hydraulic manifold manufacturer AAK detect the accuracy of valve holes after precision machining? For the testing of this manifold, we use a Swiss HEXAGON bridge type CMM. The hydraulic manifold is placed on the testing platform, and the instrument starts working. The probe for testing is placed on the valve hole. The dimensional accuracy of the valve hole and the geometric accuracy of the manifold block are controlled through a program, and the data is presented on the computer screen. The accuracy of the detection, as well as the geometric accuracy of the hydraulic manifold, especially the triangular beam bridge design, is more stable during the detection process. There is also a dovetail guide rail, which is easy to operate and does not need to worry about human error. Good precision machining indeed solves the problem of accuracy, but high-precision testing is still needed. With this dual approach, there is no need to worry about customer complaints. Hydraulic manifold manufacturer AAK, with tips for precision machining and personalized precision testing, you can also give it a try!

Broderick, from Türkiye, has been engaged in the procurement of hydraulic cartridge valves for 2 years and has been successful. Recently, Broderick encountered trouble with the SUN standard hydraulic cartridge valve CBCA-LAN purchased from a hydraulic cartridge valve manufacturer in Ningbo. The accuracy of the hydraulic cartridge valve cage is unstable, and the original manufacturer is willing to compensate, but it takes 40 days. Due to the delay in the early stage, Broderick can only leave the factory 20 days of production time. It was stuck due to time. Broderick had a very big headache. Broderick found hydraulic cartridge valve manufacturer AAK and asked if AAK could guarantee the stability of the machining accuracy of each valve cage, as well as the completion of 500 CBCA-LAN hydraulic cartridge valves in 20 days. Time is so tight, I'm a bit surprised. After communication, I learned that he purchased CBCA-LAN hydraulic cartridge valves from a manufacturer in Ningbo and encountered valve cage accuracy issues. In fact, the processing of valve cage for CBCA-LAN is not difficult, there is only one possibility. The factory did not conduct quality inspection on the accuracy of hydraulic cartridge valve cages, or only conducted spot checks. I went to the workshop to take a video of the AAK quality inspection process for the accuracy of hydraulic cartridge valve cages, and sent it to Broderick. I told him that there are less than 3 hydraulic cartridge valve manufacturers in Ningbo China who can complete the production of 500 CBCA-LAN hydraulic cartridge valves in 20 days unless they have inventory. Broderick only discussed the price for 2 rounds and confirmed the order for 500 pcs of CBCA LAN. 20 days later, AAK delivered the shipment of hydraulic cartridge valves on time. The upgrading of the testing process and 100% full inspection of the CBCA-LAN hydraulic cartridge valves are the key while ensuring stable manufacturing quality and high production efficiency in AAK. AAK fully automatic hole measuring instrument is used to detect the valve cage. After the processed valve cage enters the reserve box, there is no need for manual labor. After starting the equipment, the conveyor belt began to work and completed the detection of the outer roundness and inner hole accuracy of the hydraulic cartridge valve cage in 3 seconds, with 4 workstations working simultaneously. It can efficiently and reliably measure the outer roundness and inner hole accuracy of each hydraulic cartridge valve cage. The detected valve cage will automatically enter the push plate, and there are 4 branches on the push plate, namely valve cage scrap, qualified, utilized, and reworked. The equipment will automatically push branches based on the measurement results of the system, and qualified valve cages will directly enter the next process. AAK has been taking action to create hydraulic cartridge valve manufacturers for unmanned processes. Currently, hydraulic cartridge valve manufacturers who do not upgrade to unmanned equipment, may go to the end of their business in 5 years. What we can think of is the unmanned workshop of hydraulic cartridge valve manufacturers can minimize labor costs. The factory has fewer employees, greatly reduces management difficulty, and the key is to eliminate human error. I believe that the scale of future hydraulic cartridge valve manufacturers will no longer be measured by the number of workers, with a few or dozens of workers. The key is the hydraulic cartridge valves produced in unmanned workshops, have stable quality and low production costs. Who doesn't love them? Hydraulic cartridge valve manufacturer AAK in Ningbo China, not only fully inspects the valves, but is also more efficient than its peers. You can also give it a try!

Sheridan is from a hydraulic equipment company in Mexico, and has just been employed for less than a year. The hydraulic pilot operated proportional relief valve purchased some time ago fell him down. One of their hydraulic power units required Sheridan to purchase a hydraulic proportional relief valve. Sheridan worked with a hydraulic relief valve manufacturer in Ningbo who has cooperated with their company for 4 years to make samples. The equipment debugging was abnormal. When the rated flow was set to be large, the pressure was unstable. Their engineer asked to optimize the hydraulic pilot operated proportional relief valve, but the original manufacturer said that their hydraulic proportional relief valve met the accuracy and parameter requirements of the drawings, and had no solution to optimize the original design. Sheridan had a big head and had to look for other hydraulic cartridge valve manufacturers, but a week passed without success. Sheridan, a newcomer, was under great pressure. Sheridan found AAK on Google, noticed that AAK had solved the difficult and complicated problems of hydraulic cartridge valves, and left a message to us: Can you optimize the hydraulic pilot operated proportional relief valve and ensure the pressure is stable? At the sight of such messages, I guessed that he encountered difficulties in purchasing hydraulic pilot operated proportional relief valves. According to the original design drawing and system schematic diagram provided by him, AAK engineers worked out a plan after 1 day. Sheridan asked for samples, and AAK sent samples of hydraulic proportional relief valve 40 days later. A month later, Sheridan emailed that after replacing with AAK hydraulic proportional relief valve, the equipment was stable and had been delivered to customers for trial use. AAK hydraulic pilot operated proportional relief valve has stable operating pressure, small hysteresis and stable rated flow. We have optimized the original design from 3 aspects. 1. The side of the main valve body is provided with a valve oil inlet and a valve oil outlet, the main valve spool is installed in the main valve body, and both ends of the main valve spool are respectively provided with damping and fixed orifices. 2. The pilot valve seat is installed in the pilot valve body, the poppet valve spool is arranged between the proportional electromagnet and the pilot valve seat, and a return spring is arranged between the poppet valve spool and the pilot valve seat. 3. A force transfer spring and a spring seat are arranged between the poppet valve spool and the proportional electromagnet, a return spring is arranged between the nut and the main valve spool, the proportional electromagnet is connected with the pilot valve body and the main valve body through screws, and the cover plate is installed at the other end of the main valve body. When the proportional electromagnet has no current signal, the pressure oil enters the radial small hole of the main valve spool through the valve oil inlet, and then reaches both ends of the main valve spool. The pressure oil is connected with the pilot valve seat through the fixed orifice. The pressure oil can overcome the force transfer spring to push the poppet valve spool open and enter the oil outlet of the valve. When the proportional solenoid constant current is given, a certain thrust will be generated. The pressure oil needs to overcome the thrust of the force transfer spring and proportional solenoid, reduce the hysteresis, and ensure the stable operation of the hydraulic pilot operated proportional relief valve. AAK hydraulic pilot operated proportional relief valve, no hysteresis, and stable, you can also try a small order! https://www.aakindustry.com/info-det , ail/relief-valves-aak435

In March this year, Tancredo, an old customer from Italy, emailed me: Can you complete 50 non-standard customized hydraulic cartridge relief valves in 30 days and the valve hole accuracy within 1μm? I guess he ran into a wall when purchasing hydraulic cartridge relief valves from other hydraulic cartridge manufacturers. In the second half of last year, they developed a high-precision hydraulic pipe pressing machine, which requires the use of hydraulic cartridge relief valves. Due to time constraints, they chose samples from local hydraulic valve manufacturers, but the equipment debugging was not smooth. The pipe pressing accuracy of the hydraulic pipe pressing machine is not up to the standard, because the accuracy of the valve hole of the hydraulic cartridge relief valve exceeds 1.0μm. There is leakage. However, the manufacturer of the original hydraulic cartridge relief valve reported that there was no time to sample again and returned the development cost. The time was wasted for more than a month. Tancredo was dumbfounded. Tancredo had to try overseas hydraulic valve manufacturers, and this was why he emailed me. The hydraulic cartridge relief valve with 1.0μm hole accuracy is a big challenge for most hydraulic cartridge valve manufacturers, but AAK is confident to complete 50 non-standard customized hydraulic cartridge relief valves within 30 days. Four weeks later, 50 non-standard customized valves were sent out. Two weeks later, Tancredo emailed that their engineers were satisfied with the dimensional accuracy of the hydraulic pipe pressing machine installed with AAK hydraulic cartridge relief valves. And the hole precision of AAK hydraulic cartridge relief valves is within 0.8μm, which is 25% higher than what they required. AAK can make the hydraulic cartridge valves more accurate, and the production efficiency is faster, which is also the embodiment of AAK's capacity, and perhaps also the place where AAK is valuable. For this hydraulic cartridge relief valve, we choose OKK ultra precision machine tool from Japan. Its nanometer resolution system can ensure that the processing accuracy of components can reach 0.01~0.3μm. The precision of shape and contour is 0.003～0.1μm. At the same time, the fast moving speed of each axis reaches 60 meters per minute, which is more than 30% faster than the production efficiency of other machine tools. Fixed operation technicians in the workshop, specially assigned persons and special machines, and 2 shifts, eliminating the uncertainty in production. Tancredo told me privately that the boss was very satisfied with his quick solution this time, and he was responsible for some large purchases. AAK hydraulic cartridge relief valve, high precision, high efficiency, you can also try a small order! https://www.aakindustry.com/info-det , ail/hydraulic-cartridge-relief-valves- aak366

Last week, Beardsley, a British customer, sent us an order for 600 hydraulic cartridge directional control valves. This is the 3rd time that he reordered this valve. AAK hydraulic cartridge directional control valve, with the valve hole accuracy with 0.8μm and opening and closing within 1s, helped their equipment sell well. Beardsley contacted more than 20 hydraulic valve manufacturers before and after, but only AAK calmed his impatient heart. At the beginning of last year, they developed a four column hydraulic press. The main selling point is accurate positioning and stable control. Therefore, they have strict requirements on the accuracy and opening and closing of the hydraulic cartridge directional control valve. Beardsley firstly contacted several old hydraulic valve suppliers. After learning the parameters, they all gave up. More than 20 manufacturers of hydraulic cartridge directional control valves have been communicated online and offline, and only 2 are willing to sample. After 45 days, the valve hole accuracy of the hydraulic cartridge directional control valve samples exceeds 1μm. 2 months passed, but the manufacturer of the hydraulic cartridge directional control valve was still not approved yet. Beardsley was worried. Beardsley found AAK on Google and left a message on our website: for the hydraulic cartridge directional control valve with valve hole precision of 0.8μm, how confident are you of success? After communication, it was learned that the manufacturer of the hydraulic cartridge directional control valve had not been approved after two rounds. According to the drawing of hydraulic cartridge directional control valve provided by Beardsley, the valve hole accuracy is 0.8μm, and the opening and closing characteristics are within 1 second, which is really a challenge. I dare not say 100% sure, but there is still a 90% probability. Beardsley asked AAK to try the order first and was willing to pay the development cost. After 40 days, AAK sent the samples of hydraulic cartridge directional control valve. 3 weeks later, Beardsley told us that after installing AAK hydraulic cartridge direction control valves, the test run of the four column hydraulic machine was smooth, the positioning of the equipment was accurate and the control was stable. His impatient heart finally calmed down. For the hydraulic cartridge directional control valve with valve hole accuracy 0.8μm, the opening and closing within 1 second, AAK focused on 3 points, there is hardly a third one in Ningbo. 1. On the equipment, the German Gildemeister ultra high precision machine tool is used for processing to ensure the accuracy of 0.5-0.8μm. For most hydraulic valve manufacturers, the accuracy can only reach 1-3μm at most. AAK machining accuracy is more than 3 times of theirs. 2. In terms of development, the valve hole accuracy can be customized, while more than 95% of domestic hydraulic valve manufacturers just make the common size of the industry. Not only is it difficult to choose the tool, but also the customized processing challenges the engineers. 3. In terms of testing, we used the German Diatest high-precision small pore diameter measuring instrument to test each valve hole, while most hydraulic valve manufacturers conducted spot checks and did not have a targeted measuring instrument. AAK hydraulic cartridge directional control valve, valve hole accuracy within 0.8μm. You can also try a small order. https://www.aakindustry.com/info-det , ail/hydraulic-cartridge-directional- control-va , lves-aak365

This week, we’d like to introduce a hydraulic cartridge valve equivalent to HydraForce PR10-32. It is a screw in, cartridge style, direct acting, spool type, hydraulic pressure reducing/relieving valve with internal pilot and internal spring chamber drain. It is designed to act as a pressure regulating device for secondary circuits. It is intended for use in stable input flow circuits. Last January in 2022, a customer in Russia found AAK when looking for a hydraulic cartridge valve manufacturer in China on Google. She sent us an inquiry for 10 pcs of HydraForce cartridge valve PR10-32, along with several other HydraForce standard parts. However, AAK did not have existing programming for PR10-32 and did not quote. Instead, the customer placed trial order for the other models.   This January in 2023, the customer checked with us again if AAK is willing to develop PR10-32 as per their original samples. Although they can buy PR10-32 from other hydraulic cartridge valve manufacturers in China, they do not trust their quality. Because the quality of the other trial orders shipped by AAK last year was very satisfying, they want to develop PR10-32 with AAK. In March, the development was finished and delivered.   Last week, we were very happy to learn from the Russian customer that the E- PR10-32 Pressure Reducing/Relieving Cartridge Valve developed by AAK is running very smoothly, the quality is very stable. They are going to ask AAK to develop more and more new models.   AAK hydraulic pressure reducing/relieving cartridge valve E-PR10-32 two advantages: 1. Pressure Rating 210 bar (3000 psi), benchmarking HydraForce 2. Its service life is 2 times that of its domestic peers   Technical parameters of AAK E-PR10-32 pressure reducing/relieving cartridge valve: Pressure Rating: 207 bar (3000 psi) Flow Rating: 30.3 lpm (8 gpm) Max.

On the way home from work on Friday, I saw someone selling sweet potatoes, which suddenly reminded me of the story I had with a sweet potato peddler last winter. I remembered one particularly cold day last winter, a Chinese person from Shanghai came to Ningbo to source for a Chinese solenoid valve manufacturer for an American customer. AAK was his first stop, and the meeting lasted a long time. It wasn't until 5:30 pm that he left with satisfaction. I walked out of the factory and felt extremely cold outside. At this moment, I received a call from my wife, who said that it was particularly cold outside today and asked me to come back early. Dinner was already ready. I was very happy when I received this call, thinking that the steaming dinner at home was waiting for me, so I hurried home. On the way home, I found a person standing by the roadside. In front of him was a round stove with a pile of sweet potatoes on it. It turned out to be a peddler selling sweet potatoes while roasting sweet potatoes. I can see that he is shivering in the cold wind, but not many of these piles of sweet potatoes have been sold. I thought to myself that his task for today has not been completed yet, and the benefits for the day have not yet been realized, so he must persist here. And I, on the other hand, can immediately return home and have that steaming dinner. By comparison, compassion arose naturally. I bought 8 sweet potatoes from him in one go, and I thought to myself, if I buy one more sweet potato from him, I can make him go home earlier. I bought 8 sweet potatoes and went home with a sense of satisfaction along the way. There's nothing wrong with this sense of satisfaction, after all, I did a moral kindness and helped him. But I also have a sense of superiority, I thought to myself, after all, I am a small boss of a Chinese solenoid valve manufacturer, he is just a peddler. I returned home with this sense of satisfaction and superiority. Sitting down at the dining table, I remembered the peddler selling sweet potatoes and suddenly realized that my realm was very low. I helped him, in Buddhism, it's called giving. When I was giving to this peddler, I had a sense of superiority that was condescending. This kind of help was very self-centered and not selfless. People need to help each other, but when you help others, don't think you are one level higher than the person being helped. If I, a small boss of a Chinese solenoid valve manufacturer, urgently need help in a special occasion in the future, and in this occasion, perhaps a peddler helped me selflessly. When the peddler gives me a helping hand, if he is very self-centered, he won't help me. So I understand that the peddler selling sweet potatoes is certainly shivering in the cold wind of nature. In fact, I, a small owner of a Chinese solenoid valve manufacturer, am also shivering in another cold wind, and the wealthy on the list may also often shiver in a special cold wind. People need help from each other, and more need for selflessness. AAK, a China solenoid valve manufacturer, has been on the road, whether in the cold wind or warm sunshine.

Ryan is from a hydraulic equipment company in Brazil. In the first half of this year, they had a hydraulic logistics equipment complained by users that the control was abnormal. The after-sales engineer found that the instantaneous peak pressure of the hydraulic cartridge directional control valve was too high during the reversing process, which affected the function of the hydraulic cartridge directional control valve and led to unstable equipment control, so the hydraulic cartridge directional control valve had to be replaced. The hydraulic cartridge valve manufacturer thought that the hydraulic cartridge directional control valve was produced according to the drawing, and its function and accuracy were up to standard. The valve was tested separately and no abnormality was found. The after-sales team was helpless, and the boss asked Ryan to re purchase the hydraulic cartridge directional control valve to solve the after-sales problem first. Ryan has no idea and no direction. He spent a week without any results. Ryan found me under the introduction of his customer Bernardo, who is also a customer of AAK Hydraulic Valve. After learning Ryan's difficulties, according to his hydraulic schematic diagram and hydraulic cartridge directional control valve drawing, AAK engineers judged that the unstable control of the equipment was probably due to the original design of the hydraulic cartridge directional control valve, which had hidden dangers. I told Ryan that redesigning the hydraulic cartridge directional control valve and testing it might solve the customer's complaint at one time. After Ryan learned that AAK was 90% confident, he paid the development fee the next day. After 45 days, AAK sent 8 samples of hydraulic cartridge directional control valves. Last week, Ryan informed by email that it has been 3 months since he replaced with AAK hydraulic cartridge directional control valves. The customer is satisfied with the operation of the equipment and the control has been normal. Their engineers disassembled our samples and admired our minds. In fact, our attempt is also very simple. A damping orifice with a length of 3mm and a diameter of 2mm is added inside the hydraulic cartridge directional control valve, which can throttle the rotation of the motor, further increase the back pressure, reduce the differential pressure borne by the hydraulic cartridge directional control valve, and finally ensure the stability of the equipment rotation control. I told our engineer that the customer admired your mind. He told me that the optimization of the design of the hydraulic cartridge directional control valve was also associated with the strike of a machine tool in our workshop last time. 1. Why did the machine tool strike? Because the machine tool was overloaded, the fuse in the control panel was blown. 2. Why did overload occur? Because the lubrication of the bearing was insufficient. 3. Why was the lubrication of the bearing insufficient? Because the lubrication provided by the pump was insufficient. 4. Why was the lubrication provided by the pump insufficient? Because the pump shaft was worn, it rattled. 5. Why was the pump shaft worn? Because there was no filter at the inlet of the lubricating device, small metal chips entered the lubricating system, causing wear of the pump shaft. 6. Our coping strategy: add a filter at the inlet of the lubricating device. A simple action can effectively solve this problem and prevent it from happening again. Ryan learned that there was such a small episode, and he was very pleased with our technical team. At the same time, he told me privately that his boss was also very fond of AAK and suggested that he should discuss more difficult and miscellaneous problems of the hydraulic cartridge directional control valve with AAK. AAK hydraulic cartridge directional control valve is not only the right medicine, you can also try a small order! https://www.aakindustry.com/info-det , ail/hydraulic-cartridge-directional- control-va , lves-aak364

Galeno, from Spain, has cooperated with AAK for 2 years and tried several non- standard customized hydraulic cartridge pressure control valves. At the beginning of this year, they developed a hydraulic windlass to be promoted in the exhibition. They need a hydraulic cartridge pressure control valve for the hydraulic system of the windlass. Galeno got samples from local manufacturer of hydraulic cartridge pressure control valves. After the commissioning, the pressure control of the equipment is unstable. The engineer judged that the cavity of the hydraulic manifold was off center, resulting in unstable pressure control of the hydraulic cartridge pressure control valve after being screwed in. The hydraulic manifold manufacturer needed 2 months to re sample, but the exhibition was less than 50 days, Galeno was worried. Galeno tried to find a new hydraulic manifold manufacturer. When I received his inquiry for hydraulic manifold, I was a bit surprise. After communication, I learned that he encountered unstable pressure control of hydraulic cartridge pressure control valve. I told him that under similar circumstances, it is not necessary to re produce the hydraulic manifold. 1 year ago, AAK developed a specially designed hydraulic cartridge pressure control valve, which was specially designed to coordinate with the off center cavity of the hydraulic manifold. Galeno compared the technical parameters of the AAK hydraulic cartridge pressure control valve and it basically matched the hydraulic system of their hydraulic windlass. 2 weeks after the sample was sent, Galeno informed that the installation of AAK hydraulic cartridge pressure control valve to the equipment was smooth, and the machine test was normal. The prototype was already on the way to the exhibition. His boss was very satisfied with this urgent solution. I told him that the unique design of AAK hydraulic cartridge pressure control valve was beyond the imagination of most hydraulic valve manufacturers. We got inspiration from an old customer. The customer purchased the hydraulic manifold block and the hydraulic cartridge pressure control valve from 2 different factories. After the installation was abnormal, the two factories passed the buck. At that time, we imagined whether it was possible to let the hydraulic cartridge pressure control valve match the hydraulic manifold block with off center cavity, or vice versa. AAK technical team has figured out that the middle thread can be used in the hydraulic cartridge pressure control valve, that is, the floating structure. The connection area of the port can be optimized, and the center of the thread position can be positioned to maximize the flow capacity and minimize the eccentric influence of the hydraulic manifold block cavity. The diameter of the valve shoulder at the thread provides guidance to ensure the accurate alignment of the thread. The space of the valve shoulder is sufficient, which increases the flexibility of the installation torque and is not easy to damage the torque. The installation torque space can minimize the impact of hydraulic pressure on the valve and is conducive to pressure control. AAK hydraulic cartridge pressure control valve, specially designed to match the hydraulic manifold block with off center cavity, you can also have a small try! https://www.aakindustry.com/info-detai , l/hydraulic-cartridge-pressure-control- valves- , aak363

Bemus is from a hydraulic equipment manufacturing company in Greece. As an old purchaser, he has been working smoothly, but had trouble with a hydraulic directional control cartridge valve. In the second half of last year, they wanted to test a hydraulic power unit for drilling equipment. The shaking was serious during the equipment commissioning, which was caused by the sudden impact of the hydraulic directional control cartridge valve under the high- pressure closed circuit. The original hydraulic directional control cartridge valve manufacturer explained that the hydraulic system pressure was too high. Their engineers asked Bemus to re-purchase the hydraulic directional control cartridge valves. After a week, there was no result. Bemus was worried. Bemus found AAK in B2B and left a message on our website: How to make the hydraulic directional control cartridge valve without impact under the high- pressure closed circuit? After several rounds of communication, we learned the above problem that he encountered in purchasing of the hydraulic directional control cartridge valves. According to the video of equipment abnormality and the production drawing of hydraulic directional control cartridge valve sent by him, AAK engineer was 90% confident to eliminate the abnormality caused by the impact force. Bemus requested AAK to make samples. After 50 days, AAK sent 12 samples of hydraulic directional control cartridge valves. 6 weeks later, Bemus said that the trial run of their equipment was successful and the prototype had been delivered to the customer. AAK hydraulic directional control cartridge valve, based on the unloading valve spool, made 3 small changes to achieve pressure release. The optimized hydraulic directional control cartridge valve reduces the oil pressure in the high-pressure closed circuit and avoids sudden impact. Its stability can better control the equipment operation. 1. The unloading valve spool is arranged in the valve spool, and the control piston is connected with the push rod. The control piston can open the valve spool, and the inlet and outlet are connected, thus realizing reverse flow. 2. The unloading valve spool is connected with the spring seat, one end of the spring is fixedly connected with the top of the valve body, and the other point is connected with the spring seat. When there is no pressure oil in the control oil port, the pressure oil can only flow from the passage port to the outlet, and cannot reverse flow. 3. The bottom of the unloading valve spool is processed into a "convex" shape, which plays the purpose of unloading before the valve spool. When the pressure at the outlet is high, the control piston pushes the unloading valve spool first. When the pressure at the outlet decreases, the unloading valve spool connects the inlet and outlet. AAK hydraulic directional control cartridge valve, no impact force, and stable, you can also try it! https://www.aakindustry.com/info-detail , /directional-control-cartridge-valves- aak506

The supplier who has cooperated for 3 years has failed to test the hydraulic cartridge flow control valve for 3 times. After AAK took over, the accuracy requirements were met at one time for the sample. The surface roughness of the inner hole of the hydraulic cartridge flow control valve was 0.15, and the cylindricity error was controlled within Φ0.003mm, the operating efficiency of the hydraulic system was also improved from 5% to 10%. Brand finally came to the sunny day from the rainy day for more than 30 days. Brand is from Brazil. In March this year, he sent me an inquiry for customized high-precision hydraulic cartridge flow control valve. The surface roughness of the inner hole is Ra0.2, and the cylindricity is Φ 0.003mm. Compared with the conventional hydraulic cartridge flow control valve, the precision is improved by nearly 10%. The cylindricity and the surface roughness of the inner hole are the core of the valve hole precision. There are no more than 5 hydraulic cartridge valve manufacturers in Ningbo that can successfully sample at one time. Seven days later, Brand told AAK that the price was 20% higher than that of the other hydraulic valve manufacturers. With such a large difference, I knew that there was no comparability. The price and hydraulic cartridge flow control valve were visible, but the manufacturing quality was invisible. 40 days later, Brand asked by email how long it would take to sample the hydraulic cartridge flow control valve quoted last time. I was a little surprised. After communication, we learned that the he chose the manufacturer who has cooperated with them for 3 years to make samples for this high precision hydraulic cartridge flow control valve, but proofing failed for 3 times. There was still a 5% discrepancy on the surface roughness and cylindricity of the inner hole of the hydraulic cartridge flow control valve, which could not be achieved all the time. Their engineer blamed brand for poor procurement, and the boss was also unhappy with him. I told him that an American customer of AAK encountered similar problem a month ago, AAK solved it for him. When Brand learned of our successful case, he saw hope and was relieved. After 20 days, the samples of hydraulic cartridge flow control valve were sent successfully 2 weeks later, Brand informed that the surface roughness and cylindricity of the inner hole of the AAK hydraulic cartridge flow control valve and the accuracy parameters not only met the standard, but also improved by more than 10% compared with their original requirements. What's more surprising is that the overall operating efficiency of the system was also improved from 5% to 10% when the AAK hydraulic cartridge flow control valve was installed, which surprised their engineers. We were also complained about the surface roughness and cylindricity of the inner hole 5 years ago. Now AAK uses rolling technology to replace the traditional cutting method, uses rollers to roll the metal surface, flatten the convex part of the surface, and make the concave part bulge, and then process it into a smooth surface like mirror. The details of rolling technology need skills. The surface roughness of the valve hole processed by an old experienced craftsman will be nearly 1% higher than that of grinding, which is why we can reach Ra 0.15, and the cylindricity error is controlled within 0.003. After the working face is hardened, the wear resistance and fatigue strength are increased, which is also the advantage and feature of this process, but it requires experience to master it skillfully.
