An American IP left a message on our website: I saw your article "I regard quality as the highest principle of hydraulic valve manufacturing, why?". I want to know how AAK defines the quality of hydraulic valves. I specially checked the IP, which is an engineer from an engineering company listed in the United States. I thought for half an hour. To define a category, it must be comprehensive. What are the total quality of hydraulic valves? How much do we understand the quality of hydraulic valves? First, don't check the encyclopedia, Google, or hydraulic valve academic, but focus on hydraulic valve common sense. In common sense, how do you understand the quality of hydraulic valves, because our users also understand the quality with common sense. Friends who have read science and engineering know that there is a very famous management in Japan called total quality management. Of course, PDCA was invented by American Deming. What is carried forward is in Japan. The well- known Japanese enterprises implement total quality management. Almost all those engaged in manufacturing industry know total quality management, but few mention total quality. Some people say that total quality management has talked about total quality? Wrong, total quality management does not talk about total quality, only about management. For the total quality of AAK hydraulic valves, I have defined 4 kinds of quality. The 1st is the manufacturing quality of hydraulic valves, the 2nd is the service quality of AAK, the 3rd is the functional quality of hydraulic valves, and the 4th is the performance quality of hydraulic valves. The manufacturing quality of AAK hydraulic valves is now benchmarked with the international first-line brand, and the future is to surpass the international first-line brand. Especially in a subdivision field, such as high-pressure hydraulic valves, we should achieve top 1%. 1. AAK has been hydraulic valve ODM manufacturer for 3 of the world's top 500 for 10 years. The quality control process is strict and self-implementation is more strict than ISO certification system. 2. AAK has high-precision machine tools imported from Switzerland, Mikron GF high-precision CNC machining center and GILDEMEISTER turn milling compound machining center. 3. AAK has a full-time material engineer to check the selection of materials, which is responsible for screening, comparison, testing new materials connected with the Research Institute. AAK technical team has engineers from the world's top 500 hydraulic valve enterprises. They have their own experience in production drawing design, programming and production line quality control. Service quality of AAK: 1. AAK provides 24-hour responses, 48-hour solution plans and 72-hour problem solved before, during and after sales. Our peers dare to think but dare not to do it. 2. Six international first-line brand enterprises imported from AAK, because of feel at ease, all the hydraulic valves with low MOQ, high precision and urgent delivery, were purchased from AAK, due to AAK’s mindfulness. 3. 3-year warranty. Most of our peers dare not think about it, let alone do it. AAK hydraulic valve function quality and AAK hydraulic valve performance quality. First, let's find out what the function is and what the performance is? For example, 8 years ago, our mobile phones could not take pictures, but now smart phones can take pictures. Taking pictures on mobile phones is a function; The quality of pictures is a kind of performance. AAK hydraulic valve is differentiated and different by function and performance, especially in the field of high-pressure and high-precision subdivision, absolutely different. AAK hydraulic valve function quality: 1.The complete function of hydraulic valves is the least worth mentioning guarantee of AAK. 2.Each batch of materials shall be subject to heat treatment and never cut corners. Each hydraulic valve shall pass through the hydraulic table, with test reports and video records. Each hydraulic valve shall be tested 3 times and the test results shall be archived. 3.3 design patents, 4 proprietary production and processing technology, and the technicians in the core posts have been experienced for more than 8 years. Their proficiency is like a ruler. The old mechanic who has been in the factory for more than 10 years can sometimes judge the production status by just listening to the sound of the machine, and each production link of the hydraulic valves is engraved in his mind. Performance quality of AAK hydraulic valve: 1.The hydraulic valve with 3-year warranty has no vibration, no noise and high pressure resistance. 2.The machining surface accuracy of hydraulic valves is improved to within 0.3μm, the internal leakage can be less than 2drops / min. 3.Hydraulic valves with pressure resistance above 450bar and service life exceeding 2 million times, AAK hydraulic valve, Any valve, Any one, Any time, Any Where, just safety. Maybe I read too few books. I can tell you that almost no master, marketing master or management master has said the subject of total quality. At least, the concept of "total quality" has not been put forward in the hydraulic valve industry. I said a little more narrowly. For the definition of hydraulic valve quality, AAK is the first person to define the hydraulic valve quality with 4 aspects of total quality. AAK hydraulic valves, Any valve, Any One, Any time, Any Where, just Safety! https://www.aakindustry.com/info-de , tail/hydraulic-valves-aak233

Aether is a customer of AAK in Greece and has been purchasing hydraulic cartridge valves from AAK for 3 years. At the beginning of last year, he asked me about the sealing ring options available at AAK and I felt a bit strange. I didn't provide a direct answer and take an example, if I simply asked the doctor about the medication options, the doctor would definitely need to know the patient's symptoms or cause. After further communication, it was learned that they had encountered difficulties on a hydraulic directional control valve. Due to rapid wear of the sealing ring of the hydraulic directional control valve, there was leakage and the equipment was abnormal. The original manufacturer blamed the hydraulic directional control valve for being used too frequently, resulting in wear and tear on the sealing ring, which can only be replaced with new ones. Aether cannot accept replacing the sealing ring within only 3 months. Aether's demand is to address the issue of hydraulic directional control valve leakage without the need for frequent replacement of sealing rings. When I received the sample of the hydraulic directional control valve from the original manufacturer, I found that Aether had sent me an inquiry for this model before. I also understood why he only asked about the sealing ring at first. I told Aether that the original sealing method is a metal conical hard seal, which is difficult to ensure leakage if used frequently. Optimizing the original sealing structure can achieve no leakage for more than 1 year, but the production cost of hydraulic directional control valves would be increased. Aether was also candid and told me frankly that when inquiring, it was because AAK's price was more than 20% higher another hydraulic cartridge valve manufacturer that he chose. 60 days later, AAK sent out 50 samples of hydraulic directional control valves to address Aether's urgent needs first. Last week, Aether informed us that AAK hydraulic directional control valve has been installed on the equipment for almost a year and there are no leaks. Their customer is very satisfied, and his boss also suggested that he make AAK their preferred supplier of hydraulic directional control valves. The production cost of AAK hydraulic directional control valve is high, which is because these 3 aspects require more money than peers. AAK hydraulic directional control valve adopts a dovetail groove sealing ring through the valve spool pressure plate, which is pressed against the step hole of the valve body along with the valve spool, playing a sealing role. Oil cannot return from the inlet chamber to the return chamber, achieving zero leakage. 1. The hydraulic directional control valve body is connected to the spring seat, and the spring is fixed between the valve spool and the spring seat. There is a clearance fit between the valve spool and the valve body, as well as between the spring seat and the valve spool, to prevent the valve spool from moving inside the valve body. The guiding effect is formed between the spring seat and the valve spool, and the pre tightening force of the spring is changed by rotating the spring seat, thereby changing the opening pressure of the valve. 2. There are step holes on the valve body that guide the valve spool. There is a dovetail groove on the valve spool, which is equipped with a sealing ring to isolate the oil inlet and return chambers. Adopting a dovetail groove sealing structure and fixed by the valve spool pressure plate, it replaces the original metal conical hard seal. 3. The control rod is installed in the control chamber of the valve body, which has several oil passage grooves that return to the oil chamber and are fixed by elastic retaining rings. AAK hydraulic directional control valve, zero leakage, you can also give it a try!

Marten is an old customer from a Dutch hydraulic company. He is very cautious in the business of hydraulic valves and never changes hydraulic valve suppliers easily. AAK hydraulic valve reached the first cooperation of hydraulic relief valves under the introduction of his friend.  It has been 3 years, and he orders 2 types of hydraulic relief valves with AAK every year. We have a very good personal relationship, and often communicate about some hydraulic valve technology.   Last month, Marten had an order for a special hydraulic relief valve that requires a surface roughness Ra of 0.1~0.2μm, which is more than 4 times accurate than the normal standard.  All the hydraulic relief valves of this series are purchased from the hydraulic valve manufacturer that he has cooperated with for 5 years. This manufacturer has tried this hydraulic relief valve for 3 consecutive times, but the Ra value is still not up to standard.  Marten thinks of AAK hydraulic valve. In the email, he has been emphasized that the surface roughness Ra value of hydraulic relief valve must reach 0.1~0.2μm.  According to the hydraulic relief valve drawings sent by Marten, after discussion, AAK engineers expressed 90% certainty that the Ra value could reach 0.1~0.2μm.  Marten seems to see hope, but also fear.  He asked AAK TO try samples immediately. At the same time, the original hydraulic relief valve manufacturer was also requested to continue the sampling.   AAK arranged the most experienced technicians to operate the knife, first of all in the rough turning stage, cutting depth adjustment to 0.8~1.5mm, feed to 0.2~0.3mm/r, cutting speed to 30~50m/min and so on, after the rough turning Ra value is 12.5~6.3μm, while leaving 0.5~1mm as fine turning margin;  Secondly, in the finishing stage, the cutting depth is adjusted to 0.1-0.3mm and the small feed is 0.05-0.2mm /r. At the same time, the cutting speed is ensured to reach the moderate value and the roughness Ra value is ensured to reach 0.2-0.16μm.  AAK sent the hydraulic relief valve samples 10 days later.   On the 3rd day after receiving the samples of AAK hydraulic relief valve, Marten informed us by email that the Ra value of the surface roughness was up to standard. At the same time, he also informed that the original hydraulic relief valve manufacturer also continued the sampling, but failed in 5 samples for 5 times, while AAK succeeded in one time. He asked us to catch time to prepare material, he would discuss the PO of hydraulic relief valve with AAK after he confirmed the order quantity and the delivery date with his customer. For high precision hydraulic relief valve roughness Ra value, in addition to use high precision lathes, good technicians are the key, to be good at adjusting lathe parameters according to different processing, for this hydraulic relief valve, AAK technician advantages are reflected in:   1. High speed and small cutting depth and feed are selected to reduce the residual area and Ra value. When finishing, select high-speed and small cutting depth and feed rate to reduce the residual area and reduce the Ra value. 2. Grinding the front and rear tool surfaces of the turning tool with engine oil, can effectively reduce the Ra value of the workpiece surface. 3. The 32 year old mechanic operating the machine tool, who can know whether the Ra value of the hydraulic relief valve is normal or not by just listening to the processing sound. The Ra value of AAK hydraulic relief valve is 4 times that of the conventional standard and 2 times that of its peers. You can also have a small try. https://www.aakindustry.com/info-detail/hy , draulic-relief-valves-aak232

Mason is from a hydraulic equipment company in India. It has been 3 years since he purchased hydraulic cartridge valves from local hydraulic cartridge valve manufacturers in India. At the beginning of this year, their company developed a hydraulic crane and needed hydraulic cartridge counterbalance valves. They chose a local hydraulic counterbalance valve manufacturer who has cooperated for 5 years to make samples. During the equipment debugging, it was found that the crane vibrated during the descending process and the descending speed was abnormal. The after-sales servicer believed that the hydraulic cartridge counterbalance valve was abnormal. After the original manufacturer inspected the hydraulic counterbalance valves, all parameters were in accordance with the drawing parameter requirements. After internal discussion, it was concluded that the hydraulic counterbalance valve must be optimized, but the original manufacturer had no ability to do it. The boss asked Mason to look for overseas suppliers of hydraulic cartridge counterbalance valves. A week has passed, the manufacturer of the hydraulic counterbalance valve has not been determined yet. The boss was not satisfied. Mason began to worry. Mason found AAK on Google, stayed on AAK website for 23 minutes, and left a message: Can AAK design a hydraulic cartridge counterbalance valve to solve the instability and abnormal speed of the hydraulic crane during the descending process? For those who stay on AAK website for a long time, no matter which country they come from, as long as they are not hydraulic cartridge valve manufacturers, I will do my best to help. After communication, I learned that Mason was embarrassed to purchase hydraulic cartridge counterbalance valves. According to his system schematic diagram, hydraulic cartridge counterbalance valve drawing and crane working video, AAK engineer had a basic idea. 3 days later, AAK began to sample. After 40 days, AAK sent 6 hydraulic cartridge counterbalance valve samples. A month later, Mason emailed that after the new hydraulic cartridge counterbalance valve designed by AAK was used, the hydraulic crane did not shake during the load lowering process, and the speed was even. Their colleagues were very confident in the promotion of the cranes, and the boss was also happy. AAK does not use the traditional route to optimize the hydraulic cartridge counterbalance valve. According to the system diagram of the equipment and the abnormality of the crane, the hydraulic cartridge counterbalance valve is composed of valve body, valve seat, main valve spool, pilot valve spool and pilot mechanism. First, connect the valve seat with the valve body to establish a connected first channel. The extended end of the valve seat is connected with the pilot mechanism to establish a second channel. The main valve spool adopts sliding setting, and is equipped with throttling groove and orifice. Then the valve seat cavity is divided into 3 cavities, one end of the valve spool is in the inner cavity, and the other end is connected with the pilot mechanism. The valve spool is flexible, controllable and free from load interference. Last week, Mason told me privately that his boss decided to increase the purchase of hydraulic cartridge valves from China and give him more authority. He was more confident in his work AAK hydraulic cartridge counterbalance valve, is not only a surprise, you can also have a small try! https://www.aakindustry.com/info-detai , l/hydraulic-cartridge-counterbalance- valves-aa , k405

In the early stages of its entrepreneurship, AAK, like other hydraulic cartridge valve manufacturers in China, supplied to the domestic market. After a few years of turmoil, funds have become tight, and there are more and more customers on credit. The price competition has also become increasingly fierce. Most hydraulic cartridge valve manufacturers only focus on prices, do not make technological breakthroughs, and do not invest in innovation. I know that hydraulic cartridge valve manufacturer AAK must make changes and focus on the overseas market. My confidence stems from the stable manufacturing quality of AAK hydraulic cartridge valves, which are supplied to domestic listed companies, There is also the fact that it has never been returned. A few years ago, I didn't even know about 'brain science', I just knew I needed to write tweets, post B2B, shoot videos, and update on the website. Enquiries come one after another, including Fortune 500 companies, listed companies, and high-quality customers. Some hydraulic cartridge valve manufacturers also imitate AAK's approach by writing a few diaries, filming several videos, and doing several live broadcasts... but they can't bear it anymore, giving up is inevitable. Hydraulic cartridge valve manufacturer AAK has always insisted on writing, filming, and broadcasting. People may be curious in their hearts, where does that power come from? The answer lies entirely in brain science. In fact, many manufacturers who are persevering have not studied brain science, but their writing, filming, and broadcasting are in line with brain science, and those target customers are also people, and they must follow the principles and laws of brain science in cognition and thinking. In this way, those manufacturers who insist on writing, filming, and broadcasting will definitely have more inquiries and orders. Can we do business without understanding brain science? Of course we can. But when you understand brain science, your feelings, motivation, and mindset are completely different from before. This is how hydraulic cartridge valve manufacturer AAK gradually came to understand. The 4 books "The Consciousness Instinct", " Mind", " What Your Customer Wants and Can't Tell You", and " The Persuasion code" are all good for flipping through when you have nothing to do. If you have a lot of work to do every day, it's better to let it go for now. When you have free time, take it out and read it, perhaps it can help you understand many whys. Is the mind a product of the brain, or is it independent of the brain? Studying brain science, just like hydraulic cartridge valve manufacturers doing foreign trade, is difficult at the beginning. Just understanding a bunch of professional vocabulary first can make people retreat from difficulties. But when everyone has retreated, the hydraulic cartridge valve manufacturer AAK does not retreat. Keep going, haha, the taste is coming, and it's very good. These are new books from recent years, exploring the entry of brain science into the post brain science era, including the application of behavioral economics in marketing and sales. Just a reminder, reading these books makes it difficult for you to make money on a practical level, but I have gained a lot of inspiration from them. Hydraulic cartridge valve manufacturer AAK, has gained insights into brain science and has been involved in overseas trade.

Luca from Germany left a message on the website of hydraulic cartridge valve manufacturer AAK last Friday: Can AAK use 5-axis machine tool to produce valve cage for hydraulic cartridge valves? Luca conveyed 2 questions: whether AAK has a 5-axis machine tool and the valve cage of the hydraulic cartridge valve that he needs, is some particular. It is rare for us to receive this type of messages: using the equipment to delineate the production of cages for hydraulic cartridge valves. After communication, it was found that the hydraulic cartridge valves are to be used in their newly developed manifolds, with high precision requirements for the valve cage, which cannot exceed 2μm tolerance. In order to help the hydraulic cartridge valve manufacturer better understand his requirements, the production equipment was delineated in the inquiry, which posed a great challenge to the hydraulic cartridge valve manufacturers. The manufacturers without this equipment will be eliminated in the first round of selection. I remember that we took a video last year about the production of hydraulic cartridge valve cages by using DMG 5-axis CNC machine tool. At that time, it was a customized hydraulic cartridge valve for an Israeli customer. For the hydraulic cartridge valve with particular requirements for the cage, AAK used a German DMG 5-axis CNC machine tool. Its stable numerical control technology and stable accuracy were favored as treasures by our engineers. The processing speed reaches 20,000 rpm, with 5-axis linkage processing and equipped with a 30 position tool library. Its driving method is a direct drive ball screw drive, and all shafts adopt a linear direct measurement system to ensure that the valve cage processing accuracy is within 2μm. From the video, we can see that the technician first cleans the fixture with an air gun, then installs the hydraulic cartridge valve cage blank into the fixture, and then starts the machine tool. After processing, each valve cage needs to be measured and checked with a plug gauge. If the accuracy of the valve cage is qualified, it can be cleaned again with an air gun and then transferred to the next production process. After we sent this video to the German customer yesterday, he sent us the inquiry for a customized hydraulic cartridge valve today, with a very detailed drawing, which made us feel the rigor and professionalism of German customers again. How could it be possible for a hydraulic cartridge valve manufacturer to have no improvements if cooperating with such type of customers? This is also the benefit for hydraulic cartridge valve manufacturers working with customers with high quality requirements. AAK hydraulic cartridge valves, 5-axis equipment is ready for you, you can also try it out!

Last week, Grayson issued a reorder for 120 hydraulic pressure reducing valves. Grayson is our Canadian customer. He has been engaged in hydraulic parts procurement for many years, and his colleagues trust him. In the second half of last year, their company developed a hydraulic power unit, and the accuracy of the hydraulic pressure reducing valve used is very high. Their original manufacturer of the hydraulic pressure reducing valves reviewed but advised immediately that he was not able to meet the requirements. Grayson later found a new manufacturer of hydraulic pressure reducing valves, and the sample approval process was very smooth. Unexpectedly, customers complained about the instability of the hydraulic system less than 3 months after the equipment was sold. After inspection, it was found that the hydraulic pressure reducing valve was stuck. The manufacturer of the hydraulic pressure reducing valves said that the hydraulic oil deteriorated, and the viscous substances produced increased the resistance of the relative movement between the valve body and the valve spool, causing the hydraulic pressure reducing valve to be stuck, but their Engineer detected that the hydraulic oil was normal. The hydraulic pressure reducing valve manufacturers did not cooperate, and Grayson had to find other new manufacturers to replace those bad hydraulic pressure reducing valves. Grayson contacted a number of hydraulic valve manufacturers, but there was no reply. He was in a bad mood. Grayson accidentally found AAK hydraulic valve in Google. He left a message on AAK website and asked, what are the reasons for the stuck of the hydraulic pressure reducing valves? I'm sure he's in trouble. After communication, I learned that he was cheated by the new manufacturer of hydraulic pressure reducing valves. The valve hole of hydraulic pressure reducing valves is not only the key quality point in processing and manufacturing, but also the processing difficulty. It can fundamentally affect the working performance, service life and stability of hydraulic pressure reducing valves. The hydraulic pressure reducing valve is stuck because of the coaxiality error of the valve hole during processing, resulting in the pressure imbalance in the matching gap between the valve hole and the valve spool, and caused the stuck problem. The valve hole accuracy of Grayson's hydraulic pressure reducing valve is required to be IT7 ~ 4. Most hydraulic pressure reducing valve manufacturers can't do it, but AAK is willing to challenge the high-precision hydraulic pressure reducing valves. Grayson saw the hope and asked AAK to send 10 hydraulic pressure reducing valve samples as soon as possible. After 30 days, 10 hydraulic pressure reducing valve samples were sent smoothly. After the samples were sent out, there was no comments from Grayson about AAK hydraulic pressure reducing valves. Nearly half a year later, Grayson sent the reorder of 120 hydraulic pressure reducing valves, which proved that the previous 10 samples of AAK were up to standard. AAK has a MICROSTAR FSH high-precision machine tool imported from Germany. The machining of the hydraulic pressure reducing valve hole can be completed (expansion - boring - boring - reaming - honing) with only one clamping. The final honing process adopts ultrasonic vibration honing. Compared with ordinary honing technology, it has the advantages of small cutting force, low cutting temperature, high cutting precision, long tool life and easy treatment of chips. The dimensional accuracy of the valve hole is IT7 ~ 4. AAK hydraulic pressure reducing valves have high precision and durability.

Devante is from a Spanish hydraulic equipment manufacturing company, and has been engaged in procurement for more than 5 years. Last February, they upgraded an injection molding machine, focusing on the selling point of "high speed when empty, low speed when heavy load". The engineer asked Devante to purchase the hydraulic cartridge proportional needle valve of HydraForce. During the equipment commissioning, it was found that the pressure relief and flow of the hydraulic system of the equipment was conflicted with the hydraulic cartridge proportional needle valve, resulting in unstable operation of the equipment and jitter. HydraForce said that there was no time to customize the hydraulic cartridge proportional needle valve. Devante contacted several cartridge valve manufacturers and had no news. Devante was very worried. Devante browsed AAK website on Google and left a message: 1. Can AAK customize the hydraulic cartridge proportional needle valve, and the performance benchmarking HydraForce? 2. The function of smooth flow passage is required. 3. The function of variable flow gain is required. At the beginning, I thought that he was requested for AAK hydraulic cartridge proportional needle valve to benchmark the standard parts of HydraForce, but it was turned out that he needed us to optimize the standard parts of HydraForce. According to the equipment abnormality video, the original hydraulic cartridge proportional needle valve drawing, and their required functions sent by Devante, after discussion, AAK engineers was 90% confident. Devante asked AAK to make samples. After 40 days, AAK sent 15 samples of cartridge proportional needle valves. 2 months later, Devante informed that the market promotion of the upgraded equipment was smooth. Their engineers were satisfied with AAK hydraulic cartridge proportional needle valves, especially its variable flow gain characteristics, and smooth flow characteristics, small pressure impact during pressure relief, and accurate flow control. We mainly made 3 ingenious actions on the valve housing and valve spool, and solved the problem that HydraForce didn't want to do. 1. The lower part of the valve spool is arranged in the valve housing and sealed with the valve housing line. The upper part of the valve spool is connected with the control cover plate, the upper end of the control cover plate is connected with the valve cover with threaded holes, and the displacement sensor is installed on the threaded holes of the valve cover. The lower end of the valve spool is connected with the upper cavity of the valve spool. When the valve spool is at the lowest end, the valve is closed. When the valve spool moves upward, the valve gradually opens. 2. The lower end of the valve spool bottom is equipped with a semicircular slotted orifice. When the valve opening is small, the flow gain is small, and has good linearity, small flow, and high-precision linear control. When the valve opening is large, the flow gain is large, and it has good linearity, large flow and high-precision linear control to ensure the variable flow gain function of the hydraulic cartridge proportional needle valve. 3. The valve housing is provided with 4 symmetrical waist-shaped holes, replacing the conventional round holes. The oil flows in from the lower port of the valve spool and flows out through the waist hole, reducing the pressure impact and speed sudden change of the oil near the valve port of the hydraulic cartridge proportional needle valve, and realizing the function of smooth flow. AAK hydraulic cartridge proportional needle valve, has dual functions of variable flow gain and smooth flow.

There is a spread in the hydraulic valve industry: those who can do a good job in hydraulic valves may not be able to do a good job in hydraulic manifolds; those who do a good job in hydraulic manifolds, and basically can do a good job in hydraulic valves. Baptiste is from DMH France. The hydraulic manifolds purchased in Italy before was transferred to the hydraulic valve manufacturer who has cooperated for 4 years. However, he suffered from the 4 times a year after-sales of hydraulic manifolds. In the second half of last year, Baptiste purchased 30 hydraulic relief valves from AAK, which is the 4th time of purchasing in the year, and the quantity is the same every time. It is a little strange. After communication, I learned that a hydraulic equipment developed by them at the beginning of last year has stains on the hydraulic oil every few months, resulting in the jamming of the hydraulic relief valves. The replacement of 4 times a year keeps the customer complaining. According to Baptiste's description, the probability is that the hydraulic manifold design is improper. I suggested that he send us the hydraulic manifold drawing and system schematic diagram. Baptiste said that the hydraulic manifold drawing and system schematic diagram are confidential documents and he must get approval from boss before sending them to AAK. Three days later, Baptiste sent us the hydraulic manifold drawing and system schematic diagram, requiring that they should not be revealed to any other people. According to the analysis of the drawings, AAK engineers found that when the hydraulic power is input and the system does not start working, the hydraulic relief valve does not reach the opening pressure and cannot relieve the pressure, resulting in the increase of oil temperature and easy oil pollution. It is certain that the problem lies in the design of hydraulic manifold. I suggest redesigning the hydraulic manifold. The idea is as follows: AAK will change the 2 hydraulic relief valves on the hydraulic manifold block to use the hydraulic directional control valve alone, and change the oil circuit design. The principle is as follows: when the hydraulic system works, the hydraulic directional control valve cuts off the oil circuit, making the high-pressure oil enter the working branch. When the hydraulic system stops working, the high-pressure oil directly returns to the oil tank after passing through the directional control valve to realize zero pressure unloading. If the hydraulic manifold designed by AAK is not improved, no fee will be charged. Baptiste was a little interested after learning that. 45 days later, AAK sent a new hydraulic manifold. 4 weeks later, Baptiste informed by email that the hydraulic manifold of AAK had been used for 1 month, the hydraulic oil had no pollution, the whole hydraulic system was more sensitive, and the problem that had plagued them for 1 year was solved at one time. AAK hydraulic manifolds had been tested for first-line brands since 7 years ago. If meeting the following 3 points at the same time, there may be no second hydraulic manifold manufacturer in Ningbo except for AAK: 1. AAK technical team has engineers from the world's top 500 hydraulic manifold enterprises. They have their own experience in material selection, production drawing design, oil circuit design and production quality control. 2. Before hydraulic manifold assembly, the valve block shall be deeply cleaned to ensure 100% impurity free. Each valve shall be tested. 3. Only technicians with more than 10 years of experience are qualified to assemble the hydraulic manifolds. After assembly, use the test bench to debug the hydraulic manifolds for many times to ensure that the act function of the circuit is accurate and reliable. Baptiste privately informed that the boss was very satisfied that he found a reliable hydraulic manifold manufacturer, solved the after-sales troubles of the whole year, and could be promoted to the manager of the procurement department next month. Baptiste was so happy. AAK hydraulic manifold block is professionally designed to save you worry and effort.

Harold is from Peru and specializes in hydraulic logistics equipment. In the second half of last year, they developed a lift that experienced shaking and impact when the load was lowered. Their engineer determined that the hydraulic cartridge counterbalance valve was not satisfactory and requested the original manufacturer to improve its function, but the other party gave up. Harold spent 3 months with this hydraulic counterbalance cartridge valve manufacturer from inquiry to sample, which made him very discouraged. Harold found AAK hydraulic cartridge valves on Google search and noticed that AAK has introduced some customer cases about the solution for difficult and complex hydraulic counterbalance valves. He asked via email: Can AAK hydraulic counterbalance valves solve system shaking and impact phenomena? After communication, it was learned that he had encountered difficulties in purchasing hydraulic counterbalance valves. In fact, this is a common problem, which is likely caused by sudden changes in the flow area of the valve port, resulting in low-frequency vibration and impact. Based on his original anatomy, it's the same as what I guessed. As long as the hydraulic counterbalance valve is set with a buffering function, it can be solved. After 50 days, AAK sent 20 samples of hydraulic counterbalance valves. Harold, 3 months after the sample of the hydraulic counterbalance valve was sent out, brought me good news. This morning, when I opened my email, I saw his PO for 200 hydraulic counterbalance valves. Their engineers are very satisfied with the buffering function of AAK hydraulic counterbalance valve, and the load shedding is stable, without shaking or impact. Just like this, the additional function of AAK hydraulic counterbalance valve brings 2 advantages to his equipment. AAK does this by creating grooves on the main valve spool of the hydraulic counterbalance valve to accurately control the flow area. When the load drops, it is controlled by a gentle throttle and can also quickly buffer the impact pressure. 1. The main valve body of the AAK hydraulic counterbalance valve has a fixed first valve seat, and one end of the main valve spool is connected to the first valve seat, which slides and fits with the main valve body. The inner chamber of the main valve body is divided into the first and second chambers connected to the oil inlet, as well as the control chamber. 2. The second chamber is equipped with a second valve seat and elastic components. When the oil enters the oil inlet, the oil pushes open the second valve seat and flows to the oil outlet. The elastic component presses the steel ball onto the flow channel port inside the main valve spool through the spring seat. 3. There are multiple U-shaped grooves along the axial direction on the circumferential surface of the main valve spool, and the key lies in the depth, width, and distance between the grooves and the steel ball. AAK hydraulic cartridge counterbalance valve, has 1 additional function compared to its peers, and you can also give it a try!

Elijah is from a Canadian hydraulic equipment manufacturing company. At the beginning of this year, he encountered trouble. A batch of excavators sold by his company to Southeast Asia needed to replace the hydraulic directional valves. The main reason is that the hydraulic directional valves have been used for a long time, and it is time to replace them. The trouble is that these non- standard hydraulic directional valves from HydraForce in the United States were out of stock at the end of last year, and Elijah did not fill the inventory in time. Elijah urgently contacted the original hydraulic directional valve supplier, because these hydraulic directional valves are non-standard and were produced 2 years ago, the original supplier has no inventory now. If they are customized again, 1,000 MOQ will be required, and the production time will be 2months. Elijah fed back the information to the boss, who was angry because 60% of their company's orders came from this customer every year, and Elijah had a big headache. In order to solve the problem of time, Elijah tried to contact the hydraulic directional valve manufacturers close to Southeast Asia. The hydraulic directional valve manufacturers in China are his first choice. Elijah found AAK hydraulic valve on Google. After receiving the email, we compared the hydraulic directional valve drawings provided by Elijah. This hydraulic directional valve is not a conventional product, but he only gave a delivery time of 30 days, and the quality of hydraulic directional valve must be compared with that of HydraForce. We are worried about not the quality requirements, but the production time. Due to the particularity of this hydraulic directional valve, the process design and programming need a lot of time to complete the matching. In addition, the heat treatment and surface treatment of parts, assembly inspection and commissioning and other processes all need time. Elijah had to bite the bullet and accept our request for 40 days of delivery time. Fortunately, the design and production of this hydraulic directional valve were very smooth. 30 days later, AAK sent 50 hydraulic directional valves to Elijah's Southeast Asian factory. A few days ago, Elijah sent an email to thank AAK. Fortunately, AAK hydraulic directional valves helped him solve his urgent need. Elijah asked us how we did it. He successively contacted more than 20 hydraulic directional valve manufacturers. They all fed back that either the delivery time was too short or the quality could not be benchmarked with HydraForce. AAK is the only Chinese hydraulic directional valve manufacturer, who promised that the quality would be benchmarked with HydraForce, and the delivery date is also within 30 days. I told him that for this non-standard hydraulic directional valve, AAK has 3 points that are difficult for the other manufacturers to match with: 1.AAK is a supplier of HydraForce for 9 consecutive years, and the quality benchmarked Hydraforce is the least worth mentioning guarantee. 2.We have a high-efficiency MIKRON machining center and AMEC sinking drilling and milling cutter with central internal cooling, which allows faster cutting. In this way, human errors are eliminated in accuracy and efficient production is ensured. 3.AAK has been ODM manufacturer for 3 Fortune 500 companies for 10 years, with strict quality control process and self-implementation stricter than ISO certification system, and never relax the requirements to ourselves, stick to the details and constantly optimize the technology. AAK hydraulic directional valve is the first choice for customers in North America. You are welcome to give it a try! https://www.aakindustry.com/info-detai , l/hydraulic-directional-valves-aak229

Wagner from Germany has been communicating with hydraulic manifold manufacturer AAK via email for 3 months. He has sent 4 inquiries and we sent 2 samples. He was very satisfied with the service and communication of hydraulic manifold manufacturer AAK, as well as the manufacturing quality of the hydraulic cartridge valves and hydraulic manifolds. In early October, Wagner said he was going on a business trip to Shanghai and specifically came to Ningbo to visit the hydraulic manifold manufacturer AAK. I know that Wagner and AAK have reached a level of trust, and the order is expected next.   At 2:30 pm on October 27th, it was Wagner's arrival time at the hydraulic manifold manufacturer AAK. At 2:00 pm, I went to the conference room to check and found that there were no lights on, no fruit trays, or projectors. I asked my colleague A, and A's answer was: all of these are ready, but they have not been moved to the conference room yet. There is still half an hour left, and there are no problems in time, so you can rest assured.   After arriving at hydraulic manifold manufacturer AAK, Wagner went directly to the production workshop. 45 minutes later, he arrived at the conference room with satisfaction and a smile. All the necessary things for the meeting are ready. Colleague A opened the projector and prepared a detailed introduction of the hydraulic manifold manufacturer AAK. However, the projector couldn't be connected and it was still not done after 5 minutes. We could only use paper materials to introduce it. I also noticed that Wagner's smile was also reduced, and I realized that he cares about every detail very much. After Wagner's factory visit, although there were still email communication, no orders were placed. From the detail issue of projector, Wagner is concerned that the team did not act proactively.   If it was done 1 hour in advance and discovered a problem with the projector, it may take only half an hour to solve it, rather than reaching the cutoff point and can not resolve it. This leaves no room for oneself. For those engaged in the manufacturing industry of hydraulic manifold manufacturers, they need to consider the possibility of unexpected situations and the required room, which is what makes them adept. The cooperation between hydraulic manifold manufacturers and customers cannot always be smooth. The key is to solve it before the deadline, which is reliable. In fact, the team is the same. I entrusted the matter to my partner, once it was fine, twice it was fine, and three times it was okay. This way, I felt at ease and my trust with him was built. However, after a low-level mistake occurred once, this trust would break. Establishing trust is difficult, but it is easy to collapse.   The development momentum of hydraulic manifold manufacturer AAK is still very good, and I am racing all the way. I particularly need my partners to grow and keep up with my pace. If they don't grow and can't keep up with our footsteps, there will be break. In this situation, either I stop and slowly walk with them. Either my partners grow up closely with me and don't fall behind.   Hydraulic manifold manufacturer AAK is a team, and everyone must help and add color to this team, rather than adding obstacles. There are no small matters in production, and similarly, there are no small matters in sales. In fact, there are no small matters in every link. Grasping details, checking in advance, making predictions, and having plans are also the basic qualities of sales. To do business, it is necessary to have prior knowledge and foresight. Preparedness ensures success, unpreparedness spells failure. Early Birds Catching Worms. This is an important principle for us to do things. If the customer feels that we are not trustworthy and not keeping our promises, then they will not work with us. Hydraulic manifold manufacturer AAK in Ningbo China, be the early birds.
