Primo is from a hydraulic equipment company in Brazil. He has been smooth in this industry for 5 years, but encountered trouble in a hydraulic cartridge directional control valve. At the beginning of this year, their company sold a batch of hydraulic supports. After 6 months, the customer reported that the pipeline interface was suddenly broken. The after-sales server thought it would be OK to replace the pipes, but a week later, an accident was almost caused and the customer was angry. The original source is the hydraulic cartridge directional control valve. When the control valve is opened in reverse direction, the system oil overflows rapidly with a large amount, and the impact pressure causes the fracture of the pipeline interface. The manufacturer of the hydraulic cartridge directional control valves fed back that the high pressure and large flow under operating conditions caused abnormal control, which had nothing to do with the manufacturing quality of the valves, the only solution is to replace with new ones. Primo had no choice but to change the manufacturer of the hydraulic cartridge directional control valves. A week has passed but the after-sales plan has not been implemented yet. The boss was unhappy and Primo was worried. Primo found AAK on Google. After browsing AAK website, he left a message: How to ensure the stability of the hydraulic cartridge directional control valves with high pressure resistance and large flow? After communication, I learned that the original hydraulic cartridge valve manufacturer had no solution. I told him that AAK hydraulic cartridge directional control valve should first ensure its reliability, not replace the pipeline interface today, but replace the seal ring tomorrow, and then ensure its stability, it cannot be the case that sometimes it is abnormal, sometimes it is normal. Perhaps Primo felt that AAK was different from the other China hydraulic cartridge valve manufacturers he contacted, and asked if we could make samples according to the hydraulic cartridge directional control valve drawing and system schematic diagram provided by him. AAK engineer thought that the design of the hydraulic cartridge directional control valve should be optimized first. Primo’s engineer said that AAK can play its own role as long as the appearance and size remain unchanged and the functions are satisfied. After 50 days, AAK sent 12 samples of hydraulic cartridge directional control valves. 2 weeks later, Primo emailed that the hydraulic support could operate normally after installing AAK hydraulic cartridge directional control valves. Next, he just needed to wait for his customer to assess the stability of the hydraulic supports. I told him that he does not need to worry about the stability of AAK hydraulic cartridge directional control valves, even under high pressure and large flow, there would be no problem in 1 year. Last week, Primo sent the order for 360 hydraulic cartridge directional control valves, reminding me that this was the request of his boss. In order to avoid accidents, the boss decided to replace all the hydraulic supports with AAK Hydraulic cartridge directional control valves, because the customer was very satisfied with this after-sales plan, the hydraulic support has been used for 9 months without any abnormality. AAK hydraulic cartridge directional control valve, is resistant to high pressure and has large flow, focuses on stability and reliability, and is optimized from the following 3 points. It has impressed Primo who has been in purchasing for 5 years, and also impressed his engineers and boss, making customers more satisfied. 1. Optimize the opening of hydraulic cartridge directional control valve spool. The bigger the opening, the weaker the impact of system oil shock and fluid energy. But this opening must be moderate. If it is too large, it will backfire. Here's the trick. 2. Using the dynamic characteristic curve, the best matching between the oil pressure and the half cone angle of the small valve spool is refined. The suitable half cone angle of the small valve spool can effectively reduce the pressure impact and increase the stability during the opening process. 3. At the outer side of the large diameter end of the valve spool and at the beginning of the threaded connection on the inner wall of the valve body, a stop ring is set, which is also conducive to the stability of the hydraulic cartridge directional control valve. AAK hydraulic directional control valve, under high pressure and large flow, has twice the stability of its peers. You can also have a small try! https://www.aakindustry.com/info-detai , l/hydraulic-cartridge-directional- control-valv , es-aak407

Generally, "big factories", such as Alibaba and Google, have a special department called Research Institute. AAK hydraulic valve also has a similar department, but it is called bench department. This department has no short- term KPI and no KPI catch-up. Like an engineer's paradise, AAK hydraulic valve engineers dare to keep trying and optimizing with such an environment. In AAK hydraulic valve, the sales department makes today's money, the production department makes tomorrow's money, and the bench department makes the day after tomorrow's money. Conversely, the bench department is wasting today's money, spending tomorrow's money to do development for the sake of AAK hydraulic valve strategy and the future of AAK hydraulic valve, although the future is not clear, in my mind, they are the "special team" of AAK hydraulic valve. Making high-quality hydraulic valves can only be driven by technology. A combat team composed of several people can anchor and conquer a technical direction. The subdivided STG (Special Technology Group) focuses on innovative solutions for hydraulic valves. There has never been a shortcut or a fast track for the scientific research of hydraulic valves. Only when we settle down to do things, can we make every step steady. The reason why science and technology in this world can be developed is precisely because of the engineers' persistence, which is a long-termism and a bench spirit. AAK hydraulic valve is used in aircraft. It sounds very powerful. But it's really hard to do. Sometimes you can't see the way. Sometimes, there are many roads in front of you. Fortunately, AAK hydraulic valve chose the right path. Even if the road is tortuous, even if the road is very hard. But the right way is never far away. The bench Department of AAK hydraulic valve has to make a hard hit on this road every day. Diligence is a way to explore talents and a necessary condition for success. AAK engineers have experienced for many years. It is not difficult to combine, mutate and graft some hydraulic valve structures to create some new hydraulic valves. Instead of making some so-called patents that can't create any value for no reason, it's better to use your limited life to do something that can leave a mark on this beautiful planet. At that time, when I am old to die, on my deathbed, I will think that I have lived for so many years and made so many devices to run on the earth, which is enough to make me smile in the underworld. Bless the engineers of AAK hydraulic valve. May you have the bench spirit to conquer one mountain after another. I also wish AAK hydraulic valve a happy journey. AAK hydraulic valves, the right way, never afraid of far. https://www.aakindustry.com/info-detai , l/hydraulic-valve-aak241

China's domestic large aircraft C919 is put into market at unit price of 99 million US dollars. Most of the performance indicators of C919 are the same as those of Airbus A320 and Boeing 737. In the future of China's manufacturing industry, labor-intensive factories will be eliminated. Instead, they will focus on manufacturers with certain technical content to benchmark or gradually surpass international first-line brands. This is also the trend for Chinese hydraulic valve manufacturers. China has numerous small factories with its own proprietary technology, such as Chinese hydraulic valve manufacturers with its own unique technology. India, Vietnam and other Southeast Asian countries are unlikely to replace Chinese hydraulic valve manufacturers within 30 years. Therefore, I am optimistic about the future of Chinese hydraulic valve manufacturers, especially those with their own proprietary technology. The more high-tech, the easier it is to be eliminated. Because there is Moore's Law in the high-tech field, it will be upgraded in 18 months. However, Chinese hydraulic valve manufacturers with their own proprietary technology do not have the curse of Moore's Law, so their vitality is extremely strong and can not be easily surpassed. For example, Chinese hydraulic valve manufacturers such as AAK, it is difficult for their peers to copy and imitate, and even some international first-line brands cannot do so. AAK hydraulic valves have surpassed most Chinese hydraulic valve manufacturers in terms of function, performance or quality. 1. AAK hydraulic valve pays attention to R & D and spends money on equipment, have high precision machine tools imported from Switzerland, Mikron GF high precision CNC machining center, GILDEMEISTER turning and milling compound machining center, and various independent fixtures upgraded and refitted by ourselves. 2. AAK technical team has engineers from the global top 10 of hydraulic valve industry, who have their own experience in material selection, production drawing design and production line quality control. 3. AAK has been ODM factory of 3 Fortune Global 500 companies for 10 years, and its quality control process is strict, which is more strict than the ISO certification system. As well as never relaxing the requirements for ourselves, we are constantly improving our technology by sticking to the details. Don't say what Chinese hydraulic valve manufacturers don't have, or how impossible, people can't think about things they don't know. These are the wisdom of laymen's ignorance, and the more ignorant, the wiser. AAK Hydraulic valves: 1. The core technology, especially the production of core components, the assembly and final commissioning of hydraulic valves, is in our own hands. We never make small moves under the table. 2. The network marketing, grasps in own hand, every day outputs the difficult and miscellaneous problems of the hydraulic valves, solves the problem for the customers. 3. Free choice, positioning the quality of hydraulic valves, and positioning the customers of hydraulic valves at the same time, free choice of customers to cooperate with. AAK hydraulic valve only aims to be the leader of Chinese hydraulic valve manufacturers, and benchmarking the international first-line brands. https://www.aakindustry.com/info-de , tail/hydraulic-valve-manufacturer-aak240

Leo is a purchaser of a hydraulic equipment company in the United States. He has been purchasing hydraulic cartridge valves from China for 2 years and has been very smooth. However, in recent 2 weeks, he had a big headache due to the cage accuracy of a hydraulic directional control valve purchased from a hydraulic cartridge valve manufacturer in China. Some of the valve cages did not meet the roughness and roundness accuracy standards, which angered his engineer. The engineer requires that the Ra value of each hydraulic directional control valve cage be below 0.8 and the roundness tolerance be within 1μm. Leo found hydraulic cartridge valve manufacturer AAK on Google and sent an email asking if it is possible for AAK to ensure that the valve cage of each hydraulic directional control valve is Ra0.8 or less, and the roundness tolerance is within 1μm? After communication, it was learned that he encountered the problem of unstable accuracy at the original hydraulic cartridge valve manufacturer. According to the information provided by Leo, this is a valve equivalent to SUN Hydraulics' standard part, but the requirements for this valve cage are higher than that of SUN, in order to compatible with their hydraulic equipment requirements. Most hydraulic cartridge valve manufacturers believe that accuracy comes from production, not from inspection, so many of them overlook subsequent inspections. Hydraulic cartridge valve manufacturer AAK focuses on both. We sent Leo a video on how AAK produces and inspects the valve cage of the hydraulic directional control valve. After several rounds of communication, Leo requested AAK to send samples. Yesterday, AAK sent out 6 samples of hydraulic directional control valves for the test order. From the video, it can be seen that the equipment for producing hydraulic directional control valve cage is TSUGAMI fully automatic lathe from Japan, with the advantage of stable machining accuracy and advanced measurement and control systems. This is AAK's first-hand grasp, and the selection of production equipment is the foundation. How to inspect the valve cage of the hydraulic directional control valve is AAK's second-hand grasp. We use a pneumatic measuring instrument to detect the roughness and roundness of the inner hole, and each hydraulic directional control valve cage is inspected. AAK hydraulic directional control valve, the quality is controlled with both hands; you can also give it a try!

Hunter is an old purchaser of EAGLE PRO company in Canada. It has been several years since he purchased hydraulic directional control valves from AAK. In the second half of last year, Hunter emailed that he would become the general manager of Hangzhou branch in a month and visit AAK. Hunter has been engaged in procurement for 5 or 6 years. This promotion must be due to outstanding contributions. Some time ago, their company developed a batch of hydraulic cylinders, which vibrated greatly during commissioning. Their engineer thought that there was a problem with the hydraulic directional control valve, but the hydraulic directional control valve was normal when tested separately. The engineer was confused, and the boss was also very anxious. He asked hunter to consult the manufacturer of hydraulic directional control valves. This hydraulic directional control valve is produced by a local factory in Canada. After on-site analysis, the engineer of the original factory thinks that the vibration is caused by the sharp change of oil port pressure during the reversing of the hydraulic directional control valve. It can be solved by changing the hydraulic manifold design. The engineer's scheme is to connect two small adjustable one-way throttle valves in series on the control oil circuit at both ends of the hydraulic direction control valve. After 20 days, according to the plan of the original hydraulic directional control valve manufacturer, there was no vibration. The boss was very happy and let Hunter be promoted. Knowing that the installation of two throttle valves has increased their cost by 20%, I wonder if there is any other scheme. After getting their hydraulic direction control valve drawings, hydraulic manifold drawings and the hydraulic schematic diagram of the system, AAK engineers began to analyze. Three days later, AAK's scheme came out. The shoulder of the hydraulic directional control valve spool table was redesigned and a triangular throttling groove was added to avoid the sharp change of oil port pressure during reversing. This new design does not change the production cost of the hydraulic directional control valve, that is, it solves the vibration at zero cost. Hunter was a little incredible and asked AAK to immediately sample the new hydraulic direction control valve. One month later, the hydraulic directional control valve of AAK sample was sent out. After commissioning, there is no vibration, but the cost is zero. Hunter's boss happily saved 20% of the cost and asked hunter to always send inquiry for any hydraulic directional control valves to AAK at the first time. The design of hydraulic directional control valve runs through the whole process of design, manufacturing, use and maintenance. A good hydraulic directional control valve design cannot be separated from manufacturing. AAK engineers consider not only manufacturing, but also the function and performance of the hydraulic directional control valves, even innovation. The innovation of this hydraulic directional control valve adds a new element of triangular throttling groove on the original basis. Hunter privately informed that the boss was very satisfied that he solved the problem with 0 cost. He deserved the position of general manager of Hangzhou branch, and he worked harder and harder. AAK hydraulic directional control valve, advanced to solve problems with 0 cost, you can also have a small try! https://www.aakindustry.com/info-detai , l/hydraulic-directional-control-valve- aak239

David from Israel collaborated with hydraulic cartridge valve manufacturers in China since 2018. AAK has supplied him with several hydraulic cartridge proportional valves that are equivalent to HydraForce standard parts, and it has always been very smooth. In May of this year, a hydraulic cartridge directional valve with high requirements for cylindricity made him very upset. This hydraulic cartridge directional valve is used in hydraulic systems for navigation, with high accuracy requirements, especially the cylindricity accuracy cannot exceed 3μm. David disliked the high price of AAK, and chose another hydraulic cartridge directional valve manufacturer in Ningbo China. Later, I learned that it was just 12% higher. I told David that there are no more than 3 manufacturers in Ningbo that have this program, but not every manufacturer can control the cylindricity of each hydraulic cartridge directional valve cylindricity accuracy within 3μm. Last week, David emailed me to check if AAK can control the cylindricity accuracy of each hydraulic cartridge directional valve within 3μm. After communication, it was learned that his procurement from the other hydraulic cartridge directional valve manufacturer was not smooth. The cylindricity of the manufacturer's hydraulic cartridge directional valve hole is unstable, although most of the accuracy can be within 3μm, those unqualified hydraulic cartridge directional valves, which are not sensitive to opening and closing, have affected the entire hydraulic system. Their engineers require that the accuracy of each hydraulic cartridge directional valve hole be controlled within 3μm. The manufacturer requested a 30% increase in price because the 30% of unqualified hydraulic cartridge directional valves will be wasted. I told David that whether the cylindricity accuracy of the hydraulic cartridge directional valve hole is stable or not depends on the machining. But each one needs to meet accuracy of within 3μm, the key lies in 100% detection, and a high sensitivity cylindricity measuring instrument is required. AAK can control the cylindricity accuracy of each hydraulic cartridge directional valve hole to be 2μm, which is higher than 3μm accuracy that he requested. The detection of the cylindricity accuracy of the hydraulic cartridge directional valve hole is carried out by AAK using the Japanese Mitutoyo measuring instrument and connected to the roundness analysis software. The measurement data and graphics can be summarized and analyzed first, and then the detection results can be obtained. Especially, the Z-axis comes with a digital ruler, with a rotation accuracy of up to (0.04+6H/10000) μm. Equipped with DAT function (digital adjustment function), it avoids errors in adjusting the instrument manually and ensures timely screening of each substandard valve hole cylindricity. Most hydraulic cartridge valve manufacturers in China do not use this testing instrument and may not conduct 100% full inspection. AAK hydraulic cartridge directional valve, valve hole cylindricity accuracy, not only in processing, but also in testing, you can also give it a try!

A few days ago, an Indian friend browsed AAK hydraulic valve website and left a message: Your experience is very similar to mine. AAK's content promotion on the internet has impressed him and he also wants to try content marketing. I'm not sure if he's in the hydraulic cartridge valve industry. Before answering his question, let's first explore the marketing of hydraulic cartridge valve content. What is content marketing? How to do it? There are many ways to promote content marketing. Today, taking the AAK official website and the release of B2B as an example, I will share my experience and mindset in the hydraulic cartridge valve industry. 1. The content of hydraulic cartridge valves requires a true long-term perspective. We need to first think clearly, why do we need to do the content of hydraulic cartridge valves? What is the purpose? The purpose of AAK is to increase the credibility of hydraulic cartridge valves and cultivate trust. Imagine, there is a person who encountered a problem in purchasing hydraulic cartridge valves and nothing has been effectively resolved. What should he do? He would almost certainly search for the words "hydraulic cartridge valve" on Google, to see if there are any suggestions for solving the problem, or other hydraulic cartridge valve manufacturers. After searching, he found that out of the 100 articles, 10 were all customer cases from AAK hydraulic cartridge valves. At this point, he will leave an impression that AAK is a bit professional, and then he opens these 10 articles and takes a look, feeling that the explanation is very reasonable. So he thought, 'I want to contact AAK”. This is to increase credibility and establish AAK's trust in potential hydraulic cartridge valve customers. In this process, my deepest feeling is that the content of hydraulic cartridge valves must be a true long-term perspective. So, I have always believed that only by creating truly original and valuable hydraulic cartridge valve content can it be a friend of time. 2. Build trust with the density of time and the thickness of content. What exactly should we do? How can trust be established? AAK focuses on 2 things: the density of time and the thickness of content. If I have any hydraulic cartridge valve content that I want to write, I write it, update it if the content is good, and not update it if I don't want to write it or if the content is not good. Can we do this way? No. Daily update is necessary. Now those who do a few hours of live streaming every night, as long as they stop for a day, users may be taken away. The daily update of AAK hydraulic cartridge valve content is to cultivate user habits, otherwise everyone will forget about AAK. Its significance and value lie in using a sense of companionship to cultivate the habit of continuously reading hydraulic cartridge valve content together, giving users certainty. After outputting a large amount of content, AAK hydraulic cartridge valves have accumulated over 550 articles. These contents have thickness in the field of hydraulic cartridge valves. After this thickness accumulates, the sense of existence becomes stronger and difficult to be replaced. The advantage of the internet is that everything exists there, it has sediment and will not disappear. So, it must be more. Be sure to be thick. AAK uses the thickness of the hydraulic cartridge valve content to establish professionalism and recognition in the field of hydraulic cartridge valves, in order to increase AAK's trust. The more stored, the thicker the content, and the greater the influence. It is a forward flywheel. 3. The promotion is spreading everywhere, and there are AAK hydraulic cartridge valves everywhere on the internet The content of AAK hydraulic cartridge valves is launched on 40 B2B platforms every day. The density of time, the thickness of content, the viscosity of promotion, and the explosiveness. Good content may not necessarily lead to ultimate success, but without it, it is definitely not possible. Persist in continuous output, high-quality output, and store content of sufficient thickness in the field of hydraulic cartridge valve industry. Thank you for reading the article. Thank you for being with us. Let's continue to serve hydraulic cartridge valve industry together, think together, and grow together. AAK hydraulic cartridge valve, engaged in it for another 50 years.

Barnabas is from Pakistan, and has cooperated with AAK for 4 years. Some time ago, he contacted me and needed my help to customize a 1+1=1 hydraulic threaded cartridge valve. They have a hydraulic manifold developed by themselves. The customer feels that the manifold is too complex in the selection of cartridge valves. Their engineers asked to integrate the functions of the hydraulic relief valve and flow control valve into a hydraulic threaded cartridge valve. The cartridge valves in the manifold are all standard parts from HydraForce. For multi-functional hydraulic threaded cartridge valves, HydraForce has no time to customize it. After discussion, AAK engineers decided that it is feasible to combine the functions of relief valve and flow control valve into a hydraulic threaded cartridge valve. After 45 days, AAK sent 20 hydraulic threaded cartridge valves. Last week, Barnabas sent an email asking me to prepare the production plan of 500 hydraulic threaded cartridge valves in advance. Their manifold was recognized by customers. Their engineers were satisfied with the dual-function of AAK hydraulic threaded cartridge valves. AAK hydraulic threaded cartridge valve can not only adjust the system pressure, but also realize the easy unloading of the oil circuit when the multi-way valve stops working. Our engineers have made 3 innovations, which most cartridge valve manufacturers can hardly think of at the same time. 1. Change of valve spool: there are pilot valve spool and main valve spool, and there are 3 through grooves connected in turn. The main valve spool is at the front end of the pilot valve spool, located in the first passage slot, and the length is less than the length of the passage slot. The pilot valve spool is located in the third pass slot, the convex part passes through the second pass slot and extends into the first pass slot, and the convex slope matches the slope of the second pass slot. 2. Spring change: there is a main spring in the main valve spool. One end of the spring is against the main valve spool and the other end is against the valve housing. The outer side of the pilot valve spool is sleeved with a pilot spring. One end of the spring is against the bulge at the front end of the pilot valve spool, and the other end is against the locking structure at the rear end of the pilot valve spool. 3. Change of through-hole: the valve housing is provided with a first through- hole and a second through-hole. The first through-hole corresponds to the position of the pilot valve spool, and the second through-hole corresponds to the position of the main valve spool. The front end of the main valve spool has a filter pad, the side wall of the main valve spool has a third through hole, the front end of the main valve spool has a fourth through hole, and the filter pad has a fifth through hole. The optimized hydraulic threaded cartridge valve, when the multi-way valve stops working, the pilot valve spool moves towards the main valve spool, and the main valve spool moves towards the front end, so that the second through hole corresponds to the third through hole. The hydraulic oil passes through four through holes, replacing the functions of relief valve and flow control valve, and realizing unloading. AAK hydraulic threaded cartridge valve, replaces the relief valve and flow control valve, with 2 in 1, save you money.

At the beginning of March this year, Bartolomeo said in an email that he would like to make an appointment to consult AAK about hydraulic manifold problems. Bartolomeo, from Italy, is the purchasing manager of Italpresse Industrie Shanghai Branch. According to the communication, their company developed a hydraulic die-casting machine at the end of last year. The sales volume is just so. The general feedback is that the equipment has high energy consumption and low production efficiency. Their engineers pondered for more than 2 months, but couldn't find the reason, and the boss also had a big headache. Bartolomeo felt that the hydraulic manifold design dragged down the equipment and consulted the original hydraulic manifold manufacturer. However, the manufacturer could not put forward constructive opinions on the hydraulic manifold design. Bartolomeo thought of AAK, because AAK had proposed to modify the oil circuit when receiving the inquiry about the hydraulic manifold. According to the design drawings and system schematic diagram of hydraulic manifold provided by Bartolomeo, AAK engineers closed the door and discussed for 3 days, basically found out the direction, and it is 90% determined that there was a deviation in the oil circuit design of the original hydraulic manifold on the hydraulic die casting machine. There is an energy conflict between the original hydraulic manifold oil circuit aperture and the hydraulic valve used, resulting in the slow response of the hydraulic system and the need for additional energy to maintain the operation of the system, resulting in high energy consumption and low production efficiency. AAK can redesign the hydraulic manifold oil circuit and send hydraulic manifold samples within 30 days. Bartolomeo was very happy that AAK found the cause of hydraulic manifold problem at once. The situation was fed back to the boss, who immediately paid for AAK to redesign and test samples. A month later, AAK sent out the whole newly designed hydraulic manifold. Two weeks later, Bartolomeo emailed to order 20 hydraulic manifolds first to replace those ones on the equipment complained by customers. I was surprised that there was no comment on AAK hydraulic manifold samples but received the urgent order first. Bartolomeo advised that according to the comparison of their engineer’s on-site test run, the die casting machine with AAK hydraulic manifold has a sensitive response, the working efficiency is 11% higher than before, what’s more, the energy consumption is reduced by 30%. Their boss asked to order some hydraulic manifolds for emergency use first, and then replace all hydraulic manifolds on the original equipment with AAK shipments. AAK has professional engineers with more than 20 years of industry experience from German HAWE company, they have unique experience in hydraulic manifold design, especially in oil circuit design. Combined with the system principle, through the change of the installation form and working area of the hydraulic valves and the innovative and optimized design of the oil circuit of the valve block, and the development and application of new materials, we can produce high-efficiency, energy-saving and durable hydraulic manifolds. You may not find a second such hydraulic manifold manufacturer in Ningbo. The day before yesterday, Bartolomeo advised that the customer was very satisfied with the die casting machine replaced with new hydraulic manifolds and was ready to re purchase the equipment. The boss was very satisfied that he spontaneously sought the hydraulic manifold manufacturer to solve the old problems. The boss was going to promote him to take full charge of the work of the Shanghai Branch. AAK hydraulic manifolds make your equipment efficient and energy-saving. You can also give it a try! https://www.aakindustry.com/info-detai , l/hydraulic-manifolds-aak238
