Fossette is from a navigation and aerospace equipment company in Canada, and has been purchasing for 4 years. At the beginning of the year, their customer wanted to customize a marine hydraulic power unit, which was very strict with the hydraulic cartridge directional control valve. He contacted HydraForce for customization. Because of small quantity and tight time, HydraForce could not meet the needs of Fossette. He selected hydraulic cartridge directional control valve manufacturer in Ningbo, who has cooperated for 2 years, to make samples. The manufacturer guaranteed that the geometric accuracy of the valve spool and valve cage is 0.8μm, but it was jammed during equipment commissioning. The hydraulic cartridge directional control valve of this manufacturer is inflexible, and the accuracy is 50% lower than the requirement. At this moment, the manufacturer said that 1.2μm of hydraulic cartridge directional control valve is the limit, and their engineers can't fulfill their promises. Fossette contacted more than 10 manufacturers of hydraulic cartridge directional control valves, but it was also fruitless. The time was wasted for 6 weeks, the customer was dissatisfied, and Fossette started to worry. Fossette saw on B2B that AAK has released a customer case about "0.8μm Accuracy of hydraulic directional control valve", he left a message on AAK Hydraulic Valve website, asking 3 questions consecutively: 1. Accuracy 0.8 μm Hydraulic cartridge directional control valve, are you SURE? 2. Customization time? 3. The quantity is small, are you interested? He specially emphasized “SURE” in capital letters. He may be feared of being disappointed again. I told him that the precision of 0.8μm Hydraulic cartridge directional control valve, is already an existing fact for AAK, it is not a matter of SURE or not. I need a complete drawing to evaluate the probability of customization success as a whole. 40 days later, AAK sent 10 customized hydraulic cartridge directional control valves. After that, there was no email from Fossette, and I did not follow it. Generally, the customer will give a feedback 2-4 weeks after receiving the samples. 4 months later, just last week, Fossette informed us that his customer was very satisfied with the marine hydraulic power unit they provided. He was preparing for the annual order and asked me to keep an eye on the production in the workshop to ensure the progress and manufacturing quality of large goods. The hydraulic cartridge directional control valve accuracy within 0.8μm, challenges the processing equipment, the technical team and the manufacturer's quality awareness. 1. In terms of finish machining, OKK ultra precision machine tool from Japan is used, and AAK self modified fixture is equipped, accuracy of 0.8μm is not our limit. 2. AAK engineer team, in terms of the selection of raw materials and spare parts, starts from the requirements of working conditions and is targeted, never following the trend. Especially in the customization of high-precision hydraulic valves, the processing of production drawings, the preparation of processing technology, the technical control, they have unique skills and successful cases. 3. In terms of inspection, dare not be careless. The German Mahr cylindricity meter is used, with the help of EasyForm software, and 100% full inspection is carried out. Only those qualified can go to the packaging workshop. AAK hydraulic cartridge directional control valve, used in navigation and aerospace, you can also have a small try! https://www.aakindustry.com/info-detai , l/hydraulic-cartridge-directional- control-valv , es-aak372

Today, AAK posted a Pilot-Operated, Pressure Reducing/Relieving Valve benchmarking SUN Hydraulics' PPFB series, and we have developed 3 sub categories: E-PPFB-LAN; E-PPFB-LDN; E-PPFB-LWN. The working characteristics of this pilot operated pressure reducing/relieving valve are: the pilot operated valves exhibit exceptionally flat pressure/flow characteristics are very stable and have low hysteresis. Pilot operated reducing/relieving valves by nature are not fast acting valves. For superior dynamic response, consider direct acting valves. The function of this pilot operated pressure reducing/relieving valve is to reduce a high primary pressure at the inlet (port 2) to a constant reduced pressure at port 1, with a full-flow relief function from port 1 to tank (port 3). In the past 6 months, AAK have received 2 orders from a Brazil customer. The selling points of this pilot operated pressure reducing/relieving valve are: 1. Control Pilot flow: 10 - 15 in³/min, Benchmarking SUN 2. The service life is 2 times that of domestic peers in China Technical parameters of AAK E-PPFB Hydraulic Pilot-operated, pressure reducing/relieving valve: Max. Operating Pressure: 350 bar (5000 psi) Capacity: 20 gpm (80L/min) Control Pilot Flow: 10 - 15 in³/min.

Coleman is from a hydraulic equipment company in Ecuador. He has been engaged in procurement for 3 years and has been quite smooth. In the second half of this year, the hydraulic winches they have sold out for 8 months was complained by customer that they were slipping under load and were prone to shake. After checking, it was found that the hydraulic cartridge counterbalance valve in the system was abnormal. The original manufacturer of the hydraulic cartridge counterbalance valve said that under such working conditions, the hydraulic counterbalance valves would need to be replaced every 8 months. The boss was not satisfied with this short service life and asked Coleman to find a hydraulic counterbalance valve manufacturer who can guarantee a longer service life. Coleman was surprised that all other hydraulic counterbalance valve manufacturers he contacted said that the original manufacturer was correct. Coleman saw AAK on Google and sent an email for inquiry with the attitude of trying. After communication, we learned his purchasing status. According to his hydraulic schematic diagram, working condition requirements, and hydraulic counterbalance valve drawings, AAK engineers also agreed with the opinions of the original manufacturer, but AAK has an optimization plan, and can guaranteed a service life of at least 16 months. When Coleman learned that AAK wanted to optimize the structure of the original hydraulic counterbalance valve, he hesitated and worried that it would affect the function, and his engineers may not accept it, so there was no news from him for a week. 7 days later, Coleman told us that he had no choice but to pay for the development cost by himself to request AAK samples. After 45 days, AAK sent 12 hydraulic counterbalance valve samples. Last week, Coleman sent an email to us that the equipment installed with AAK hydraulic cartridge counterbalance valves ran stably without any functional impact. 8 months have passed and the customer has no complaints. I told him that even in another 8 months, the customer wouldn't complain. AAK optimized the hydraulic counterbalance valve with minor changes in 3 aspects, which is not only more stable and better, but also more durable. 1. In the inner chamber of the hydraulic counterbalance valve spool, the boss for axial limit is machined. The piston slides in the second chamber. The rear end of the piston is equipped with a one-way throttling device (the first damper and the second steel ball). 2. The main valve spring adopts multiple spring structures with different stiffness, and the chute on the cone side of the valve spool can control more accurately and sensitively to prevent the load from stalling. 3. The second steel ball is placed in the third chamber of the piston and matched with the valve port of the first damper. The rear end of the screw plug is provided with a damper, which has two damping links. The utility model reduces the system pressure, reduces vibration, is beneficial to stability, and is durable. AAK hydraulic cartridge counterbalance valve, stable and durable, you can also try a small order! https://www.aakindustry.com/info-det , ail/counterbalance-valves-aak436

Leila is from Russia. It has been 2 years since she purchased cartridge valves from China. She has encountered difficulties in the accuracy and stability of hydraulic pressure control cartridge valves. In February of last year, their hydraulic pile driver was complained by customers about its inability after 6 months of use. After checking, it was found that the hydraulic pressure control cartridge valve had leakage. The original manufacturer of the hydraulic pressure control cartridge valve advised that that this valve spool accuracy requirement was high, some hole accuracy of the valve spool may be not up to standard and caused the leakage. It could only be re-produced, which took 60 days. The after-service sales had to deliver other pile drivers to the customer for use instead temporarily. The boss was not satisfied with the original hydraulic pressure control cartridge valve manufacturer, and required Leila to re-purchase the hydraulic pressure control cartridge valve, which must be completed within 40 days. Leila was under pressure. Leila left a message on AAK website: 1. For the hydraulic pressure control cartridge valve, with accuracy of each valve spool is below 0.8μm and consistent, is AAK able to customize it? 2. Can AAK finish 20 customized hydraulic pressure control cartridge valves within 40 days? 3. The service life of the customized hydraulic pressure control cartridge valve shall be 18 months. This is about the accuracy, production time and service life of the hydraulic pressure control cartridge valve. After communication, I learned that she had trouble with the stability of the accuracy of the valve spool, and saw the information of AAK hydraulic cartridge valve on B2B. I told her that AAK had encountered these 3 problems before, and there were also practical solutions for customers. Leila asked me to make samples according to her drawings. After 38 days, AAK sent 20 samples of the hydraulic pressure control cartridge valves. Yesterday, Leila emailed us that the pile driver equipped with AAK hydraulic pressure control cartridge valve has been running for almost 1 year without leakage or complaint. AAK hydraulic pressure control cartridge valve has been approved by her boss. They are counting how many hydraulic pressure control cartridge valves need to be purchased to replace those with hidden dangers. With the recognition of her boss again, Leila was relaxed and pressureless. AAK hydraulic pressure control cartridge valve has fulfilled 3 major requirements of Leila, by making efforts in material selection of valve spool, component processing, equipment selection and quality control. 1. The valve spool material 20CrNi2MoV, imported from Germany, is adopted by AAK, combined with AAK's personalized carburizing pretreatment process, through secondary quenching + cryogenic treatment + low-temperature tempering process, the microhardness of the valve spool is 237~247 HV, and the service life of the valve spool has been increased by at least 3 times. 2. The processing equipment adopts Japanese OKK ultra-precision machine tool, and the old technicians operate the tool to ensure the accuracy of valve spool can reach 0.3-0.5μm. And the production efficiency is more than 30% faster than other machine tools. 3. In terms of the testing instrument, the German Diatest micro-pore diameter measuring instrument is used, which can inspect each valve hole accurately. AAK hydraulic pressure control cartridge valve, has consistent accuracy and service life of more than 18 months.

Evelyn is from a hydraulic equipment company in Mexico. He has been engaged in the procurement of hydraulic valves for 5 years and has been very successful. However, the hydraulic cartridge directional control valves purchased in the early stage fell down. At the end of last year, their excavator was complained by the customer that the output power was unstable. The after-sales server believed that the leakage of the hydraulic cartridge directional control valve was probably the cause. After disassembly, it was true that there was a gap between the valve spool and the contact point of the valve hole. The original manufacturer of the hydraulic cartridge directional control valve reported that after more than 10 months of use, individual leaks were unavoidable, and the hydraulic cartridge directional control valve could only be replaced. However, 1 month later, more and more complaints were filed. Evelyn realized that the service life of the valve produced by this manufacturer is about 1 year, or 500,000 to 700,000 times of performance. Evelyn started to send inquiries for "2 drops/min hydraulic cartridge directional valve with a performance of more than 1.5 million times". After 1 week, there was no quotation from any hydraulic valve manufacturers. Evelyn had a big headache. Evelyn found AAK on Google and left a message: 2 drops/min hydraulic cartridge directional valve with a performance of more than 1.5 million times, can it be guaranteed? I told him that this hydraulic cartridge directional control valve with high requirements for both function and performance is actually a benchmark for the manufacturing quality of HydraForce. AAK has served HydraForce for 9 consecutive years. If this is a real order, try it directly. If you just ask about the price, don’t waste time on both sides. After 35 days, 20 hydraulic cartridge directional control valves were sent out. Evelyn informed by email last week that the excavator with AAK hydraulic cartridge directional control valve has been installed for 1 year, and no customer complained about abnormal output power. I told him that the performance of this model can reach 2 million times, which is 3 times of that of your original hydraulic valve manufacturer, as long as no one does anything wrong about it. Evelyn is relieved. AAK can achieve 2 drops/min of hydraulic cartridge directional valve with a performance of 2 million times, which is the result of adhering to the quality standard of HydraForce. AAK spends no less than 400,000 dollars on R&D and technology upgrading every year. 1. AAK has produced OEM hydraulic valves for 3 world top 500 companies for 10 years. The self executing quality control process is more strict than the ISO certification system. It is focused on manufacturing details, process innovation and technology research and development. HydraForce and SUN Hydraulics are also loyal customers of AAK, and have been cooperating continuously for 9 years. 2. The AAK engineer team, in terms of the selection of raw materials and spare parts, starts from the requirements of working conditions and is targeted, never following the trend. Especially in the customization of hydraulic cartridge directional control valve with high requirements, there are some tricks and cases. 3. AAK has a self-developed test bench, each valve is 100% fully inspected from function to performance, while most hydraulic valve manufacturers just conduct random inspection. AAK hydraulic cartridge directional control valve, 2 drops/min, with a performance of 2 million times, you can also have a small trial! https://www.aakindustry.com/info-det , ail/hydraulic-directional-control-valves- aak37 , 1

Reading and earning money are the best practices in life. The former is not confusing, while the latter gives people dignity. It is important for hydraulic manifold manufacturers to earn money by reading more books. Many times, most hydraulic manifold manufacturers are not doing themselves, but imitating others. They are not operating their own hydraulic manifold manufacturers, but envying other hydraulic manifold manufacturers. They are not pursuing the manufacturing quality of hydraulic manifolds, but copying others' pleasure. The root cause of a person's unhappiness lies in comparison, comparison, and the final result is frustration and self denial. In life, we often only see the scenery of others, but ignore their vicissitudes. The most precious thing at the moment is what you currently have. Hydraulic manifold manufacturer AAK receives inquiries from customers every day, which is our most precious. Only by comparing fewer and cherishing more, can hydraulic manifold manufacturers gain a sense of trust. When no one helps you, stand tall on your own. When no one helps you, work hard and believe in yourself. As long as you are brave enough, there are no difficulties you cannot overcome! The best state for a person is not to expect or envy anyone, not to underestimate anyone, not to ridicule anyone, not to rely on anyone, to clarify and transparent their inner selves, to have the courage to say yes, and the confidence to say no! Whether brave or confident, there is a beauty like jade in books. Without sufficient orders, hydraulic manifold manufacturers are unable to read. Even holding a book but thinking about the order, you can't even read it. With sufficient orders, hydraulic manifold manufacturers can read effectively. Hydraulic manifold manufacturer AAK is reading while comparing its own online dissemination of hydraulic manifolds, thinking where else needs improvement. How can a hydraulic manifold manufacturer be able to get into a book if they lack money? Lack of money is a vicious cycle that is difficult to change. In this state, most of the decisions made by hydraulic manifold manufacturers may be wrong and short-sighted, focusing only on the immediate situation. How can there be good results? The anxiety of lacking money is the biggest anxiety among all anxieties. Many people say they are lost, but in fact, they are anxious about lack of money. To change this fate, they need guidance from a noble person. Hydraulic manifold manufacturer AAK has today's insights, and can always focus on the stability of manufacturing quality without comparing with domestic hydraulic manifold manufacturers. It is thanks to the distinguished customer of hydraulic manifold manufacturer AAK (the guidance of Honeywell, a Fortune 500 enterprise). If a hydraulic manifold manufacturer does not have stable manufacturing quality, no matter how beautiful the words are, they are all floating clouds. Hydraulic manifold manufacturer AAK in Ningbo China, makes money while studying, always remembers the words of the distinguished person and follow it, are also brave and confident.

Why is there only price war when there is no intermediary in cross-border e- commerce? Is there no selling point and no reason to buy? Chinese hydraulic valve manufacturers can't play cross-border e-commerce without their soft power and hard work. I have a friend. His factory produces leisure chairs. Three years ago, he started a cross-border e-commerce business of leisure chairs in Amazon. After several months of accumulation, he told me that the business was stable. Full containers were shipped to overseas warehouses. The average monthly sales volume was 1,000 pcs, the overall profit was 30%, and the flow was stable. I curiously went to his online shop to see, "There is no middleman making the difference, only my leisure chair", occupying a prominent position. I told him at that time that this model could not last, and he thought I was jealous of him. Yesterday, he complained to me. On September 1, a home furnishing big seller started to sell the same leisure chair at a 35% price reduction. As a result, his sales volume was only 50 pcs, and his traffic declined seriously due to the price reduction of the big seller. He had no choice but to reduce the price by 35%. Sell one now and lose 5 yuan. He is hesitating whether to continue the price war? If you don't, the traffic will disappear. If you do, there will be no bottom. Why did I tell him that this model would not work. Because I was impressed that it was just a brick mover, without the selling point of leisure chairs and no reason to buy, burning advertising to drive traffic. Is this cross-border e- commerce? With few or no peers, you can make big money with your eyes closed. As long as there is a peer, we must fight for the price.If a bunch of peers are here, the money earned should be vomited back slowly. A few days ago, I read a report that a delivery clerk at Amazon who had worked hard for 4 years received a dismissal letter from AI on his way to delivery, because it took too long and exceeded the standard operation time. Note that it is not HR. For repetitive, fixed action work similar to brick moving, AI can issue dismissal notice without HR in future assessment. People still need to think. Especially their soft power and hard work. Chinese hydraulic valve manufacturers, as cross-border e-commerce companies, should be careful if without endorsement of manufacturing quality. From beginning to end, online trust is the first priority. The content of the detail page of the Chinese hydraulic valve manufacturer must be of quality, not the hydraulic valve manual. Even if you want to send a lot of B2B information, let's say that the customer must know: 1) Why am I trustworthy? Many times, people are more important than goods 2) Why is the AAK Hydraulic Valve also trustworthy? 3) Compared with peers, what are the technical parameters and quality indicators of AAK hydraulic valve that have been compared with the international first-line brands? 4) Which 3 global top 500 and international brands are loyal customers of AAK hydraulic valves? It has been used for several or more years 5) AAK Hydraulic Valve, how to solve the problems of the hydraulic valves purchased by customers? 6) If you want cheap or low-quality hydraulic valves, you should not contact AAK to waste each other's time. Chinese hydraulic valve manufacturers must have quality in their work, which is not correct nonsense. The content is related to the customer and benefits the customer. This is the king of content. Chinese hydraulic valve manufacturers do not need to increase much flow. One inquiry of hydraulic valves from one target customer per day is OK, that’s 365 customers a year. If business is done with 10% of them, which are 36 customers. The small day of Chinese hydraulic valve manufacturers is OK. In fact, the same goes for salespeople. Isn't the salesman your own boss? The salesman who works to achieve the work goal is a fake salesman. AAK hydraulic valves, benchmarking the international first-line hydraulic valve brands, such as HydraForce, serving 3 global top 500 companies. https://www.aakindustry.com/info , -detail/chinese-hydraulic-valve-manufacturers- , aak370

1 year ago, Ferdinand from Germany left a message on AAK Hydraulic Valve website: Is there a hydraulic cartridge check valve equivalent to HydraForce? Ferdinan bought two hydraulic cartridge check valve samples from the model number I provided, then there was no news. Three months later, he bought another two samples of hydraulic cartridge check valves equivalent to SUN. Six months later, he sent a customized hydraulic cartridge check valve drawing and brought 6 samples, there was no email for 6 months. I think it's a bit abnormal, but if something is abnormal, there must be evil. He bought hydraulic cartridge check valve samples from AAK 3 times a year to test my patience and inspect the manufacturing quality of AAK. I can only comfort myself in this way. Last month, Ferdinand sent an email asking about the lead time for 1,200 pcs of hydraulic cartridge check valve customized last time. I knew that AAK had passed the investigation period of German customers. After communication, I learned that the hydraulic cartridge check valves that he purchased in Ningbo 2 years ago, were tested with 6 hydraulic valve manufacturers before and after. Either the first sample was OK, but the second one was not up to standard; Either the existing valve was tested OK, but the customized valve was abnormal. Time was wasted and delayed their equipment development. It turns out that Ferdinand was feared by some hydraulic valve manufacturers, so he was prudent to select new hydraulic valve manufacturers. This time, they will develop a hydraulic boarding bridge, which requires non- standard hydraulic cartridge check valves. From trial order to large order, AAK has been investigated for more than 1 year. Ferdinand said that the manufacturing quality of AAK hydraulic valves, whether the ones benchmarking international brands or non-standard customized ones, had been recognized by their engineers for their functions and performance, so they decided to place large quantity order of hydraulic cartridge check valves. The reason why AAK hydraulic cartridge check valve is different from other hydraulic valve manufacturers in Ningbo is that we insist on the quality of manufacturing. 1. Not make do with the equipment. No matter CNC machining center or machine tool, only high-precision ones are selected. At the same time, the fixture is upgraded and modified by ourselves, eliminating human error. 2. Materials should be paid attention to. Different kinds of imported high carburized bearing steel should be combined with AAK's proprietary heat treatment process. The hardness of the material has gone up several steps, and its wear resistance has been improved by more than 3 times. The thermal stability and compressive strength of materials have been far ahead of other hydraulic valve manufacturers. 3. The inspection is vigorous. The high-precision test bench and durability test equipment independently developed by AAK are used to conduct 100% full inspection. The pressure, flow and fatigue resistance of the valve cannot escape Sun Wukong's eyes. AAK hydraulic cartridge check valve, insists on high quality. You can also have a small try! https://www.aakindustry.com/info-detai , l/hydraulic-cartridge-check-valves-aak369

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
