Valves

At the beginning of this year, Samuel asked by email about the production time of 1,000 hydraulic needle valves, He specially emphasized that the technical parameters of the hydraulic needle valves need to be the same as those samples made before, especially the valve hole accuracy must be 100% within 1μm or less. Samuel has been cooperating with AAK for 3 years. It is the first time that he deliberately emphasized as such in email. After communication, I learned that the hydraulic needle valves that AAK made samples for last time was 20% higher than that of other hydraulic valve manufacturers, so he placed the order with another manufacturer. However, now this batch of hydraulic needle valves have been complained by customers that the hydraulic winch is stuck. The root cause is that the accuracy of the hydraulic needle valve holes is uneven, and some are less than 1μm, and some higher than 1μm. After the original hydraulic needle valves were replaced by the manufacturer, complaints still continued. The boss was very dissatisfied with Samuel's purchase this time and asked him to source another hydraulic needle valve supplier. Samuel can only get back to AAK, because the sample accuracy of AAK hydraulic needle valve hole was 1μm or less. I told Samuel that the shipment of AAK hydraulic needle valves has never been lower than the sample standard. The next day, Samuel sent us the PO of 1,000 hydraulic needle valves. After 45 days, AAK delivered 1,000 hydraulic needle valves. Last week, Samuel sent an email saying that AAK hydraulic needle valves had been installed on the equipment for more than half a year, and no complaint was received. His boss would rather spend 20% more cost and must purchase the hydraulic needle valves with valve hole accuracy 1 μm for 100%. I told him that even if AAK hydraulic needle valve is used properly in another year, it will not get stuck. Samuel was surprised at how AAK ensured 100% accuracy of the hydraulic needle valve hole within 1μm? For the control of the manufacturing quality of hydraulic needle valves, AAK's 3 characteristics lead the majority of hydraulic valve manufacturers. 1. On the processing equipment, the valve hole is finished with the TAMIX one- time tool walking high-speed ultra precision honing mill imported from Japan, which is thoroughly ground without traces. In mass production, the wear- resistant SPA tool effectively ensures the stability of processing, and the valve hole accuracy is guaranteed to be 0.8-1.0μm and the surface roughness reaches Ra0.2-0.3. 2. In the processing process, AAK has more than 10 years of experienced technicians with special machines and special personnel, who have engraved the dimensional accuracy of each element in their minds. 3. In terms of processing and inspection, after the valve hole is processed, Diatest small pore diameter high-precision measuring instrument imported from Germany is used to accurately measure each hydraulic needle valve hole, and the minimum measurement accuracy range can reach 0.1μm so as to ensure that the accuracy of each product meets the standard.

This Monday, we posted a new model benchmarking SUN Direct-acting relief valve, RDBA-LEN, RDBA-LAN. The Direct-acting relief cartridges are normally closed, pressure-limiting valves used to protect hydraulic components from pressure transients. When the pressure at the inlet (port 1) reaches the valve setting, the valve starts to open to tank (port 2), throttling flow to limit the pressure rise. These valves are smooth and quiet, essentially zero leak, dirt tolerant, immune to silting and are very fast. From the inquiries and orders that we have received, RDBA-LAN seems to be more widely used. We have 6 inquiries for RDBA-LAN, but only 3 inquiries for RDBA- LEN. The selling points of the Direct-Acting Relief Valve are: 1.Response Time – Typical 2 ms, benchmarking SUN, no secondary factory in Ningbo 2.Quiet, zero leak Technical parameters of AAK E-RDBA Hydraulic Direct-acting Relief Valve: Max.Setting: 350 bar (5000 psi) Capacity: 12 gpm (48L/min) Maximum Valve Leakage at Reseat: 10 drops/min. Response Time – Typical: 2 ms Temperature: - 30°C to 120 °C   Cavity: SUN T-162A AAK Direct-Acting Relief Valve with 3 major advantages, benchmarking against SUN RDBA, you can also give it a try.

Brishen is from Brazil. He has been purchasing hydraulic valves for 4 years smoothly, but was stumped by a hydraulic cartridge pressure control valve recently. At the end of last year, their customer wanted to customize a hydraulic power unit for the hydraulic system of aviation equipment, which has high requirements for the cartridge pressure control valve. Brishen chose a local manufacturer who has cooperated with their company for 3 years to make samples for the hydraulic cartridge pressure control valve. 2 weeks later, the manufacturer reported that it was too difficult to process this hydraulic cartridge pressure control valve. Especially, the length diameter ratio of the slim hole of the valve spool guide sleeve was 11∶1, and the hole cylindricity was within 2μm, the scrap rate of the sample is 50%, and the processing efficiency is extremely low and it is too difficult to control the cylindricity. Brishen contacted more than 10 cartridge valve manufacturers. No factory was willing to make samples. They either rejected due to small qty or could not overcome the processing difficulty. Brishen was worried. In B2B, Brishen noticed the article about the length diameter ratio processing of AAK hydraulic valve, and felt that the length diameter ratio of 11∶1 might not be a problem for AAK. He emailed me to ask that for the hydraulic cartridge pressure control valve, with the length diameter ratio of the slim hole of the valve spool guide sleeve as 11∶1, and the hole cylindricity within 2μm, dimension tolerance within 1μm, what is the lead time and development cost for AAK to make samples? My reply: Thank you for your trust in AAK. This cylindricity precision is high, and ordinary cartridge valve manufacturers can't make it. Similar processing technologies were produced in batches by AAK 3 years ago, and now it is more and more mature. After 50 days, AAK sent 12 samples of hydraulic cartridge pressure control valves. 1 month later, Brishen sent an email to inform that their engineer was satisfied with the size and accuracy of the AAK hydraulic cartridge pressure control valve. It was installed on the hydraulic power unit, and the overall operation was stable. The equipment had been delivered to their customer. It was estimated that there would be a batch order 6 months later. AAK hydraulic cartridge pressure control valve indirectly controls the cylindricity from the 3 factors of straightness, taper and roundness during processing, including 3 points: 1. In the rough machining link, the gun drill is improved and a new process is developed. First, a pilot hole is machined. The coaxiality of the machined hole is within 0.02mm and the straightness is within 0.01mm. 2. In the rough honing process, the honing rod with the size of about 120% of the hole length is selected, and the straightness of the valve hole after processing can reach within 3μm, the taper reaches within 2μm. Most cartridge valve manufacturers are easy to make bell mouth because of the poor grasp of the honing bar size. 3. In the finishing link, first trim the grinder with a taper of within 0.3μm, set the length of the grinder to 90% of the hole length to ensure the cylindricity of the slender hole of the valve sleeve is within 2μm, dimension tolerance is within 1μm. AAK hydraulic cartridge pressure control valve, with high precision and stability, you can also have a small try! https://www.aakindustry.com/info-detai , l/cartridge-pressure-control-valves- aak428

At the beginning of the year, Torsten, an old customer of AAK, was in urgent need of 200 hydraulic directional control valves and specially emphasized delivery within 30 days. I felt Torsten was in big trouble. Torsten from the Netherlands has cooperated with AAK for 5 years. In case of trouble, basically, he consults me first. It turned out that their hydraulic pipe jacking machine was complained by customers half a year after sales. During construction, the equipment suddenly dropped. The problem was that the hydraulic directional control valve leaked, causing the hydraulic system not to maintain pressure. The manufacturer of the original hydraulic pressure directional control valves was willing to replace the faulty hydraulic directional control valves for free. However, there were more and more complaints later, and the manufacturer was helpless. The boss was very angry and requested Torsten to re source a reliable hydraulic valve manufacturer with a guarantee of more than 1 year service life. Torsten was under big pressure. According to the hydraulic directional control valve drawing sent by Torsten, the pressure resistance is 380bar. The leakage of the original hydraulic directional control valve is caused by wear. If there is no wear, material selection is the key. Due to time constraints, Torsten did not ask AAK to make samples first, but directly produce 200 hydraulic directional control valves on-line. I think this should be Torsten's trust in AAK. After 30 days, AAK delivered 200 hydraulic directional control valves. Yesterday, Torsten sent an e-mail to inform that it has been 7 months since the hydraulic pipe jacking machine installed with AAK hydraulic directional control valves, there is no complaint about equipment dropping. I replied to him: Don't worry. The service life of more than 1 year is the most basic line of AAK. Your boss will not criticize you any more. It is AAK's commitment to double the service life of peers. AAK hydraulic directional control valves, pressure resistance 380bar, and no wear for more than 1 year. Our valve body is made of Japanese SCM415 chromium molybdenum steel alloy steel, whose mechanical properties are more than 70% stronger than those of similar materials. Then carburizing and heat treatment shall be carried out. The hardness of the valve body shall be more than HRC65, and the wear resistance shall be more than 3 times that of the general 45 steel to ensure no wear for more than 1 year. For the hydraulic directional control valves with high pressure resistance and service life of more than 1 year, the material selection is the key, but the carburization and heat treatment of the material are the core. The reason why most hydraulic valve manufacturers dare not use SCM415 chromium molybdenum steel alloy steel is not only the difficulty in processing, but also the inability to control carburization and heat treatment. There are unique skills here. AAK hydraulic directional control valves, no leakage, no accident, you can also try it! https://www.aakindustry.com/info-detail , /hydraulic-directional-control-valves- aak336

Caleb from Mexico, needs to purchase hydraulic relief valves suitable for seawater. Several local hydraulic relief valve suppliers dare not quote because of the uncertain working environment of seawater medium. Caleb had to try to find overseas manufacturers of the hydraulic relief valves. Perhaps because there is no overseas procurement base, there are few hydraulic valve manufacturers willing to cooperate, which makes Caleb helpless. When he almost gave up, his friend Ron learned his situation and suggested him to contact AAK Hydraulic Valve. Perhaps AAK can bring him an unexpected surprise. After receiving an email from our old customer Ron, I learned about the dilemma that Caleb encountered on the purchase of the hydraulic relief valves. According to the hydraulic relief valve drawings and working environment instructions sent by him, I told him about the strong corrosiveness, low viscosity, high vaporization pressure and temperature difference of seawater. This hydraulic relief valve must be corrosion-resistant, impact resistant and highly sensitive. AAK shipped hydraulic valves for marine climate 3 years ago. According to the specific requirements of the hydraulic relief valve, our engineer suggested to modify the original design. Caleb felt that AAK was different from other hydraulic relief valve manufacturers. Our 3-step adjustment scheme is as follows: 1. Change raw materials and hydraulic components: replace conventional alloy steel with corrosion-resistant alloy engineering plastics. The valve spool material is 17-4PH, the valve cage material is PEEK, the valve body is 316L, and the spring is Ni36CrTiA1. Even if they are immersed in seawater all year round, they will not corrode for 365 days. 2. Add a damper to reduce the impact vibration of the valve. Because the density of seawater is large, but the compressibility and viscosity are small, its vibration and impact are more prominent than other media. Adding a damper can slow down and prolong the service life of the hydraulic relief valve by more than 30%. 3. The flat valve port is adopted to replace the original cone valve. Under the same pressure difference at the valve port and the same flow rate, the opening of the flat valve is smaller than that of the cone valve, thus improving the pressure regulation accuracy of the valve. After receiving our suggestions, Caleb overturned his understanding of the hydraulic relief valve, and even thought that AAK was incredible. After verifying with Ron again, he realized that AAK was really different from other hydraulic valve manufacturers. Ron told him that either you believe in AAK or you don't waste time in Ningbo. Caleb paid the development fee with anxiety. 30 days later, that is, in the middle of last month, AAK sent out the samples of hydraulic relief valve. Today, we received the PO of hydraulic relief valves of US $6,600 from Caleb. In the email, he was excited to inform that the whole system has been running for 1 month with AAK hydraulic relief valves, and there is no abnormality. He also advised that AAK will be their only overseas hydraulic valve supplier. AAK customized hydraulic relief valves, can be used in seawater for 365 days without problem. Welcome to try it! https://www.aakindustry.com/info-detail , /hydraulic-relief-valves-aak335

How much money a person can earn, depends on their own cognition. How much money Chinese hydraulic manifold manufacturers can earn, depends on the cognition of the leaders. When a Chinese hydraulic manifold manufacturer stands high, and no matter what difficulties they encounter, what they see is not a problem, but rather an opportunity. If you live on the first floor, under your balcony, and someone scolds you, you can hear it clearly. If you live on the 10th floor, even though he is scolding you and pointing his fingers, you can't hear him clearly and think he is greeting you. If you live on the 30th floor, no matter what he is doing, you can't see clearly and don't care anymore. Standing on the 50th floor or above, when you look at the urban area of Ningbo, all you see are scenery, beautiful, and comfortable. When your floor is low, everything you see is a problem. If your floor is high, everything you see is beautiful. In the manufacturing industry, especially for Chinese hydraulic manifold manufacturers with hydraulic technology content, the most important issue is the cognition of leaders. If these Chinese hydraulic manifold manufacturers do not have sufficient cognitive dimensions, communication between hydraulic manifold customers and you will be very tiring, especially when there is a conflict of interest. These Chinese hydraulic manifold manufacturers cannot compromise, and all the reasons are their height of the cognition. The manufacturing capacity of Chinese hydraulic manifold manufacturers determines their today, and their recognition determines their tomorrow. People cannot earn money beyond cognition, and similarly, Chinese hydraulic manifold manufacturers cannot earn money beyond cognition. There is a small story to share with everyone. 2 years ago, Mazen from Palestine sent me an assembled hydraulic manifold and he only needed to purchase 2 pcs. Unfortunately, there are two hydraulic cartridge valves that need to be developed. I hesitated a bit and was also searching for existing hydraulic cartridge valves in my industry to replace the customer's original design. I replied to Mazen, "It's a bit troublesome, please let me advise after checking. I was a bit busy during that time, so I shelved responding to Mazen's email for a week. Mazen sent an email saying, 'I guess you are encountering difficulties, and I can understand that. Before you, 6 Chinese hydraulic manifold manufacturers had already given up. I currently cannot afford to buy hydraulic manifold developed in Italy, but I believe there are Chinese hydraulic manifold manufacturers that can get it done. Mazen's words are very frank. I know that most of them have biases towards some customers, and the development of new hydraulic manifold not only consumes time, but also has uncertainty. From development to mass production, to functional testing, and life testing, it takes time and money, and this hydraulic manifold is a bit novel, with selling points from design to functionality. After several rounds of communication with Mazen, he said that after 1 year, AAK can promote this hydraulic manifold to other customers. After 4 months, AAK sent 2 samples of the hydraulic manifold. 1 year later, due to authorization from Mazen, we have sold this hydraulic manifold to 6 customers as of now. What Chinese hydraulic manifold manufacturers are unwilling to do, AAK can. AAK HYDRAULIC VALVES (683) 2023-10-01 https://www.aakindustry.com/info , -detail/hydraulic-manifold-manufacturers-aak683

Lawrence is from Italy. He has been purchasing hydraulic components for quite a long time, and it is relatively smooth. In the second half of last year, when purchasing hydraulic pressure control valves with 1μm precision valve spool, he encountered problem. Their company has developed a hydraulic shear with double cylinder steel structure. The adjustment of the blade clearance of the hydraulic system depends on the hydraulic pressure control valves, especially the precision of the valve spool should be controlled within 1μm. A hydraulic valve manufacturer that has cooperated for 5 years made the samples for this hydraulic pressure control valve, but the scissors clearance was not sensitive. The engineer found that the valve spool of hydraulic pressure control valve moved abnormally. The manufacturer of the hydraulic pressure control valves has no confidence in the improvement of the accuracy of the valve spool. 5 weeks wasted and Lawrence had to find a new hydraulic valve manufacturer. But 1 week later, only 1 manufacturer was willing to try samples, and he was only 70% confident. The engineer has pushed for several times, and Lawrence is worried. Lawrence found AAK Hydraulic Valve in Google and left us a message: valve spool accuracy 1μm hydraulic pressure control valves, how confident? I told him that AAK had produced 0.8μm valve spool. Lawrence immediately sent his drawing of hydraulic pressure control valve. I suggested direct sampling. Lawrence agreed and informed that there was another manufacturer to sample at the same time. 4 weeks later, AAK sent the hydraulic pressure control valve samples. 1 week later, Lawrence told AAK that the hydraulic pressure control valve had high sensitivity and solved the problem of abnormal scissors clearance. However, the samples from another manufacturer have the similar problem to that of the original manufacturer. Their hydraulic shear equipment is on the way to the exhibition. He wants to know how AAK can achieve the sensitivity that other manufacturers can not. AAK hydraulic pressure control valves, high precision, high sensitivity, due to 3 points: 1. On the equipment, the valve spool is processed by the full-automatic grinding machine of Japan long island Seiko. The surface of the processed valve spool is like a mirror, with an accuracy of 0.8μm, which provides a guarantee for the accuracy of the valve spool. 2. In terms of selection, 60Si2CrVA alloy steel pressure spring made in Japan is selected for this hydraulic pressure control valve. Its tensile and yield strength is at least 30% higher than that of high-end piano steel wire pressure spring, which provides a guarantee for sensitivity. 3. In terms of detection, the German Diatest small pore diameter high-precision measuring instrument is used to detect the valve hole of each hydraulic pressure control valve to ensure the consistency of concentricity and provide a guarantee for sensitivity. AAK hydraulic pressure control valves, triple guarantee, easy to use, long service life, you can also try a small order. https://www.aakindustry.com/info-det , ail/hydraulic-pressure-control-valves- aak334

With more cooperation with customers, no matter what country they come from, or what mother tongue they speak, or what personality they have, they naturally influence and pay attention to each other. A few days ago, Lim, an American customer who has cooperated for 11 years, came to learn from the experience that "AAK has no peers". Today, Raheem, from Turkey, who has cooperated for 6 years, is also paying attention to we media of AAK Hydraulic Valves. He also wants to try. AAK Hydraulic Valve has been doing We-media for 2 years. My feeling is that we must not underestimate We-media. From the beginning to the present, AAK Hydraulic Valve has been updated and original, recording and disseminating cases of AAK hydraulic valve solving difficult and complicated problems for customers. Although the current short video is also very popular, AAK Hydraulic Valve self-media still hasn't given up. As a hydraulic cartridge valve manufacturer, AAK has only six or seven office employees, we need two people to engage in We-media. A large proportion of people who make hydraulic valves are engaged in the work of We-media. In the current era, to be honest, the power of we-media is imaginable. It is difficult for others to understand his creativity in the position of we-media. Others always think that you have no value in writing an article. We media is the most efficient creation of AAK Hydraulic Valve. Although it is very virtual, it has no input, equipment and actual output, but it is a window for an enterprise to solve the future sustainable development. From the perspective of trust, promotion and customer connection, it is actually inseparable from this. If we don't insist on doing this, AAK Hydraulic Valve can never reach the current level, and our tentacles can never be extended so widely. Every continent has our customers, and our hydraulic cartridge valves are supplied to most countries with manufacturing industries. The density of the net formed by it is constantly increasing, so that AAK Hydraulic Valve can take the initiative. Instead of looking for customers everywhere and sending development letters to customers everywhere, customers come to us with this trust. In business, there is a game between the two sides of cooperation. The one who has the initiative and the one who has the trust will go ahead. From the perspective of harvest, it is not only about the operation of hydraulic valve enterprises, but also about thinking. It is more important to realize the cognition brought to us by human growth, as well as the iteration and force of cognition, as well as the influence of informatization. Everyone of AAK Hydraulic Valve has improved their cognition, thus improving the overall cognition of AAK. In this way, I regard Internet We-media as the ecology of your personal growth and enterprise growth. AAK Hydraulic Valve is built on its our quality. It does not make small moves. It keeps a diary every day. It is to bear the customer's trust in AAK. https://www.aakindustry.com/info-detai , l/hydraulic-cartridge-valve-manufacturer- aak49 , 9

Last Sunday, I went to the countryside to attend a friend's daughter's wedding, and I haven't seen a wedding in the countryside for a long time. It took over 2 hours of driving to arrive. The wedding scene was very touching. Nowadays, there are almost no rural people who get married without wearing wedding dresses, but 30 years ago, people were all dressed in bright red. Whoever marries in a white wedding dress will definitely be scolded.   In ancient China, there were two women, one beautiful named Xishi and the other ugly named Dongshi. Dongshi envies Xishi's beauty and constantly imitates her every move. One day, Xishi suffered from a heart ache and walked on the street covering her chest with her hand. Her eyebrows furrowed tightly and looked very charming. Upon seeing it, Dongshi thought it was very beautiful. She also covered her chest with her hand, frowning and making eyes. When people on the street saw her, they all retreated and thought she was mentally ill.   Imitation without understanding is the current situation of many people in Chinese society. Among these Chinese solenoid valve manufacturers in Ningbo, they all want to imitate HydraForce or SUN solenoid valves, but how many of them are completely benchmarking the manufacturing quality, function, and performance of HydraForce or SUN? AAK is the supplier of HydraForce for 9 consecutive years and Sun hydraulic for 5 consecutive years, rooted in our manufacturing quality inspected for 9 or 5 consecutive years, this is also AAK's confidence as a Chinese solenoid valve manufacturer.   I have also attended weddings of Western friends, but we have overlooked the fact that the focus of a foreigner's marriage is the wedding oath: whether in good or bad times, wealth or poverty, health or illness, happiness or sorrow, I will always love, cherish, and be loyal to you forever and ever. Who remembers these words, the older sisters who have worn wedding dresses and the uncles who have married in western style weddings? Have uncles who have been married for N years ever regretted when their wife is no longer beautiful? Have the older sisters who have been married for N years ever complained about their husband's incompetence? For the proposal, in fact, the cultural background of Western wedding lies in Christianity. The so-called proposal is to let everyone supervise openly. You can't go to others anymore. It advocates monogamy. So those who casually sleep with others before marriage must not engage in foreign weddings, be careful if God punishes you; Those who have engaged in foreign weddings should not cheat after marriage, nor should they dislike each other for various reasons. Be careful that if God is effective, he will send you to hell.   There is an old Chinese saying: Don't burn incense casually! This sentence has a profound meaning behind it! Chinese solenoid valve manufacturers should not imitate casually, but instead focus on manufacturing quality, increasing the procurement cost of materials or accessories by more than 15%. The 1st step in improving quality is to eliminate cutting corners. Some Chinese solenoid valve manufacturers rely on cutting corners to earn profits, which is annoying. The 2nd step is to increase the processing cost by more than 10%, increase the number of quality inspectors for key processes, and assign responsibility to individuals. The 3rd step is to strictly implement the production process and not be careless. Only with the determination to manufacture quality and the guarantee of quality on the production line, can Chinese solenoid valve manufacturers have a tomorrow.   AAK, a solenoid valve manufacturer in China, does not imitate, only benchmarking, and focus on quality control from 3 aspects.   AAK HYDRAULIC VALVES (583) 2023-05-14 https://www.aakindustry.com/info , -detail/solenoid-valve-manufacturer-aak583

Bartolomeo is from Italy, and their company has developed a hydraulic drill used in the deep sea. Bartolomeo has purchased several customized hydraulic valves from AAK, but has not purchased any hydraulic manifold blocks yet. Their hydraulic drilling rig has the requirements of corrosion resistance and pressure resistance of 450 MPa for the hydraulic manifold blocks. Bartolomeo is an experienced purchaser. He contacted more than 10 hydraulic manifold block manufacturers and asked if they were able to make samples. Only 1 of them was willing to try. Bartolomeo felt that if only 1 manufacturer, there will be no comparison and alternative choice, so he contacted me to ask if AAK is willing to test the hydraulic manifold blocks with another manufacturer together. I rarely refuse such direct PK. After 35 days, we both got the hydraulic manifold blocks pass the testing. However, the quotation of AAK hydraulic manifold blocks was 20% higher than that of the other manufacturer, and this PO was lost. But I'm not surprised. I feel that this PO will come back. 9 months later, Bartolomeo suddenly asked me by e-mail whether the hydraulic manifold blocks we made samples last time could ensure a service life of more than 1 year. I asked him, is the service life of the hydraulic manifold blocks of that cheaper manufacturer less than 1 year? He told the truth that the customer complained that the surface of the hydraulic manifold block was seriously corroded, especially there was leakage at the oil pipe interface, and the pressure supply of the equipment was unstable. That manufacturer has surrendered and can only guarantee the service life of 8-9 months. I told him that the hydraulic components made by AAK last time, can ensure a service life of more than 1 year, no matter it is used in the desert or deep sea, whether at high temperature or low temperature, Although the price is 20% more expensive, the service life of the hydraulic manifold blocks is twice that of the peers. Bartolomeo sent an order for 100 hydraulic manifold blocks the next day. The reason why the service life of this hydraulic manifold block is 2 times that of its peers is due to 3 points: 1. This hydraulic manifold block is made of CEJN stainless steel imported from Sweden. Its corrosion resistance is 3-5 times that of most steels, and its hardness can withstand 600MPa. Even the thin wall of the through hole is not deformed under high pressure. 2. In terms of processing, the composite tool is selected to process the bottom hole of thread, 45 °, 15 °, R0.1 chamfer and external counterbore at the same time. In the process of one-time processing, it can complete the combination of different processes such as drilling, reaming, reaming, spot facing and boring, with high efficiency and small error. 3. In terms of detection, the high-pressure manifold block test bench independently developed by AAK can simultaneously detect the compressive performance of different parts of the hydraulic manifold blocks. AAK high pressure hydraulic manifold blocks, super corrosion resistant, you can also have a small try! https://www.aakindustry.com/info-detai , l/hydraulic-manifold-blocks-aak333

A few days ago, Ren Zhengfei, President of Huawei, made an internal speech about "surviving", which affected the outside and also had a great impact. The boss of a trillion level enterprise said that the global economy will continue to decline in the future, and the domestic economy will also be grim. Subsequently, social media interpreted that large enterprises were going to survive the winter, and that small enterprises were going to die. It seems that large enterprises catch a cold, and small enterprises must be in the late stage of cancer. What is the logic? I have always said that pessimists are right and optimists make money. In any case, pessimists who have been singing down China can hardly make money. The more optimistic you are, the more confident and powerful you will be. The more gloomy you are, the less action you will take. For example, the sales volume of AAK Hydraulic Valve, which is less than 30 million US dollars, is a drop in the ocean. I would say that it has nothing to do with the economic environment. Those small and medium-sized Chinese hydraulic valve manufacturers have little to do with the whole country and even the global economy. Small and medium-sized Chinese hydraulic valve manufacturers should keep up their spirits, insist on manufacturing quality, focus on the subdivided hydraulic valve market, and be big fish in the small fish pond. For those small and medium-sized Chinese hydraulic valve manufacturers whose sales have declined, please do not comfort yourself with the words of the big boss. You are not at the same level. Small and medium-sized Chinese hydraulic valve manufacturers with this spirit should wake up quickly, or they will be really unlucky. I think that in the winter of large enterprises, the spring of small and medium-sized enterprises has come. Although the total market demand is indeed much less, because large enterprises can not support and do not participate, they release a large number of orders, and small and medium-sized enterprises happen to receive such orders. When the sky fell down, there were large enterprises. They were the first to be unlucky, and they could not be pressed on the small and medium-sized Chinese hydraulic valve manufacturers. The feeling of winter may only be that the temperature has dropped a few degrees, which has no effect on the body feeling. AAK adheres to the principle of "3 axes", focuses on the manufacturing quality of hydraulic valves, promotes the marketing of AAK hydraulic valves and serves customers well. Let Internet users around the world understand the characteristics, advantages and benefits of AAK hydraulic valves, as well as the differences with small and medium-sized Chinese hydraulic valve manufacturers. I think that the winter of large enterprises has ushered in the spring of small and medium-sized enterprises. Drinking milk to supplement calcium, few people will doubt its correctness, but many doctors recommend drinking soymilk in the morning. Why do we think that the absolutely correct facts are not necessarily right or even absolutely wrong? Should we need to see things on social media? To see, the key is to have your own independent thinking. But it's not easy to think independently. Do you think you can think independently if you close the door and sit there alone? At least I'm not very confident about my independent thinking. Think, think independently, that's right. But thinking must have a foundation of thinking. Usually, my method is to read more books, especially those classic or relatively classic books, and absorb some basic things from those books. This is several times more than independent thinking without any cognitive foundation. Therefore, while reading classic books, we should also keep pace with the times, and books closely related to the times are also essential. It's better to read the book in 20% and 80%. 20% of the classics and 80% of the books are closely related to the times. Ren Zhengfei's theory of "surviving" is also in line with business common sense. No matter what time, the first task of a large enterprise is to "survive". Only by living can it continuously create value. Objectively speaking, it is not a bad thing to have a little pressure and worry and make people feel a little crisis. In addition, Huawei's theory of "surviving" is not pessimistic. In fact, it expresses that "I can survive and live well", which is obviously optimistic. Small and medium-sized Chinese hydraulic valve manufacturers, it is difficult to do things, which is objective and must be admitted. Pessimists say "I don't live", optimists say "I want to live". When ordinary people complain, Sakyamuni also complains. Then why can he become a Buddha? Because in addition to complaining, he also broke the pain and enjoyed it. Small and medium-sized Chinese hydraulic valve manufacturers should, like Sakyamuni, break through hardships, seek pleasure and go their own way. AAK has always been an optimist of small and medium-sized Chinese hydraulic valve manufacturers.

Yesterday, a new Indian customer visited Chinese hydraulic manifold manufacturer AAK. They were previously hydraulic manifold manufacturers in India and have been purchasing from Chinese hydraulic manifold manufacturers in recent years, focusing on hydraulic equipment such as logistics transmission and lifting. They are two brothers, and this is their second time coming to Ningbo. After the meeting with Chinese hydraulic manifold manufacturer AAK, they made a request to take them to a temple near Ningbo to see. I was stunned for a moment, thinking I had heard wrong. After confirming again, they really wanted to take a walk to the temple. This is the first time for Chinese hydraulic manifold manufacturer AAK to have encountered such a customer proposal in 8 years. Chinese hydraulic manifold manufacturer AAK took them to the most ancient temple in Ningbo - Ashoka Temple. On the way, I was thinking that they might have had a fate with AAK. In recent years, due to a large number of domestic orders, most Chinese hydraulic manifold manufacturers have been very proud, which is also normal. Because when people are proud, they do not think of danger in times of peace. People always think of safety when they are in danger. When I feel good about myself and seem a bit bloated, I will go to the temple or look at the sea. At that time, I suddenly quieted down, and at the same time, I felt really insignificant. On the way, the Indian brothers said that when they were tired from work, they usually went to the temple for a visit. This was their first time visiting a Chinese temple. I introduced the Asoka Temple in Ningbo to them, which is the least commercial ancient temple in Zhejiang. It is a very primitive temple, and every day, monks are arranged to explain Buddhism to visitors, listen to it, and understand it. The ancient trees in the temple are towering, and the indoor wooden windows are fragrant with sandalwood. As soon as you enter, your heart calms down for a third. We arrived at the gate of the temple at 11 o'clock. At the entrance, there was a temple specific incense, which was provided free of charge to pilgrims. They were all devout in offering incense and worshipping the Buddha. After a while, a master knocked a copper bell with a long wooden stick. The monks heard the bell sound and rushed in. This is the temple bell for eating, and it should be lunch time for the monks. They sat silently at the dining table one by one, each with 3 empty bowls in front of them. Soon, several masters came up and distributed their meals one by one, including stir fried bean sprouts, tofu, green vegetables, and so on. After the distribution was completed, everyone folded their hands and recited the scriptures, then they chewed slowly and ate quietly. Half an hour later, the visitors were also invited to a vegetarian fast, and the Indian brothers also wanted to try. We came to the cafeteria and the food was buffet style. We chose shredded seaweed, potatoes, winter melon, some rice, and a bowl of mung bean soup. We didn't say a word, we enjoyed the delicious vegetarian food very much, eating it all up and the plate looks like being licked. Subsequently, we escorted our Indian brothers back to the hotel, and they were very grateful and enjoyed the unique time with Chinese hydraulic manifold manufacturer AAK. Chinese hydraulic manifold manufacturer AAK, goes to a temple to worship the Buddha and have a quiet heart. Zero yourself, just to be better on the road.

Dorian is from a Greek hydraulic equipment company and is responsible for the procurement of hydraulic components. At the beginning of the year, they developed a new hydraulic crane, which requires the use of hydraulic counterbalance cartridge valve. Dorian worked with a local manufacturer to make samples. During the equipment commissioning, it was found that the hydraulic counterbalance cartridge valve had no overflow function due to the back pressure. The hydraulic system was tested separately, but it was normal. Dorian felt that there was a hidden danger in the original design of the hydraulic counterbalance cartridge valve. The engineer thought that the function of the hydraulic counterbalance cartridge valve was not up to standard. Dorian was a little embarrassed. Dorian found website of AAK hydraulic valves on Google, and noticed that AAK had been supplying first-line brand hydraulic valves such as HydraForce, SUN Hydraulics, and HAWE for many years. Maybe he saw hope and sent an email to ask for help. According to what he said, the hydraulic counterbalance cartridge valve has no overflow function under the influence of the back pressure of the closed central circuit. I told him that it was probably a flaw in the design of the original hydraulic counterbalance cartridge valve. According to his hydraulic schematic diagram and original drawing of hydraulic counterbalance cartridge valve, AAK engineer not only determined that the problem was in the original design, but also had a solution. After knowing these, Dorian asked AAK to make samples. After 50 days, AAK sent 10 hydraulic counterbalance cartridge valve samples. 4 weeks after AAK hydraulic counterbalance cartridge valve samples were sent, Dorian told me that the equipment debugging was smooth and the market promotion had been started. I was asked to wait patiently for the batch order. The rapidity and stability of AAK optimized hydraulic counterbalance cartridge valve is the key to smooth equipment commissioning. It solves the contradiction between the rapid response and stability of the equipment in the early stage, and the flow change is moderate, the movement is stable, the safety overflow function is not affected by the back pressure, which can be applied to the closed center and open center hydraulic systems. 1. The middle section of the hydraulic counterbalance cartridge valve spool is provided with an inner concave ring, which is also the valve inlet. The right end of the inner concave ring has a cone, on which there is a two-stage stepped taper ring. The cumulative area of the cone is the same as the area of the cylinder end face at the right end of the counterbalance cartridge valve spool. This not only challenges the selection of design data, but also challenges the processing settings and processing technology. 2. The cylindrical end face at the right end of the hydraulic counterbalance cartridge valve spool is equipped with a balance adjusting spring. The adjusting screw at the back end of the spring is sealed with the back end of the counterbalance cartridge valve body, and controls the expansion and contraction of the counterbalance adjusting spring. 3. Fixed damping is installed between the inlet of the automatic closing valve and the pilot oil port. The hydraulic automatic closing valve is used in parallel with the adjustable flow valve to compensate the pressure without being affected by the back pressure. AAK hydraulic counterbalance cartridge valve, not affected by back pressure, you can also try a small order! https://www.aakindustry.com/info-det , ail/counterbalance-cartridge-valves-aak427

Giuseppe is from a hydraulic equipment company in Italy. As an old purchaser, he has been enjoying good luck. In the second half of last year, their company obtained the annual order of hydraulic power units used for the tail plate of electric vehicles, but the customer requested that the price should be reduced, and the hydraulic directional control valves used in the power unit should be reduced by 10%. The manufacturer of the hydraulic directional control valves who made the samples for them also agreed to reduce the price, but hidden trouble was brought to the quality at this time. In the random test of the electric vehicle, the tail plate did not rise flexibly. After disassembly, it was found that the hydraulic directional control valve was stuck. The manufacturer of the hydraulic directional control valves advised that it is an individual phenomenon, but the customer does not think so. After increasing the detection ratio, some tailboards still can not be opened. The customer asked for immediate solution, otherwise the annual order would be cancelled. The boss was very angry and requested Giuseppe to solve it. Giuseppe contacted more than 20 manufacturers of hydraulic directional control valves. They either disliked the low price or could not guarantee that there was no jamming. Giuseppe at this time is under great pressure. Giuseppe contacted me. Due to price, our cooperation is sporadic. According to the hydraulic directional control valve drawings provided by Giuseppe, AAK found that the original design caused processing difficulties and processing costs. I replied to Giuseppe that if the original design can be modified, AAK can accept the price and guarantee 100% no jamming. After 45 days, 100 hydraulic directional control valves were sent. A week later, Giuseppe sent the shipment schedule for the annual order. 8 months have passed. Last week Giuseppe informed that the customer wanted to ship the last batch of hydraulic directional control valves in advance. After using AAK hydraulic directional control valves, the customer no longer complained about the inflexible lifting of the tail plate. The hydraulic directional control valve is 100% free of jamming, due to 3 points: 1. The hydraulic directional control valve newly designed by AAK belongs to the spool valve type. The original vertical poppet type design is replaced by the "tumbling head" type design. The original function is not changed, and can be used to compensate for the imbalance of the valve spool in the chamber. At the same time, it can effectively compensate the original high torque in the assembly process, so that the valve spool can be controlled freely. Double protection hydraulic directional control valve, without jamming. 2. AAK adopts Swiss high-precision honing machine to finish the valve spool and cage, and the accuracy is guaranteed to be within 1μm. Unstable accuracy is the root cause of the stuck hydraulic directional control valves of the original hydraulic valve manufacturer. 3.AAK Hydraulic Valve has developed no less than 500 non-standard customized hydraulic valves for 7 world top 500 enterprises. If without unique skills, it is difficult to handle. Giuseppe privately told us that the boss attached more and more importance to him and wanted him to lead the whole procurement team because he successfully saved the annual order. AAK hydraulic directional control valves, flexible and free of jamming, you can also try it! https://www.aakindustry.com/info-detail , /hydraulic-directional-control-valves- aak331
