Valves

Davis comes from a hydraulic equipment company in the United States. He has cooperated with AAK for 4 years, and it is very smooth. It is strange that since an inquiry of hydraulic pressure control valves in the second half of last year, there has been no new inquiry from him, only the reorders of some hydraulic cartridge valves. At the beginning of August, Davis asked about the production time of 200 hydraulic pressure control valves, and only then did we know that why he did not place orders for new valves for a long time. In the second half of last year, he found a hydraulic valve manufacturer whose price was more than 20% cheaper than that of AAK, so he moved the business to that manufacturer. But now troubles come out one after another, the boss is very dissatisfied, and he is under great pressure.   The most troublesome thing is that a three grip electro-hydraulic puller is weak in grasping due to the leakage of the hydraulic pressure control valve. However, the manufacturer of the original hydraulic pressure control valves prevaricated, and the high frequency of use of the equipment caused the wear of the valve body, and even refused to replace the goods. Davis regretted his decision. He caused big trouble for the first time because of the 20% price difference, and had to get back to AAK. In the past 4 years of cooperation with AAK, there was no complaint. In order to help Davis get out of the predicament as soon as possible, we adjusted the production arrangement of the workshop. 2 weeks later, 200 hydraulic pressure control valves were delivered. Davis also sent me the drawings of other valves produced by that manufacturer with lower price, and asked me to be prepared for production.   AAK hydraulic pressure control valve is wear-resistant and leak free, ahead of most hydraulic valve manufacturers in 3 aspects, which are also the important points to ensure the performance of 2 million times.   1. In terms of materials, AAK adopts German 20CrNi2MoV high carburized bearing steel. Through secondary quenching + cryogenic treatment + low temperature tempering process, its microhardness is 237 ~ 247HV, and its wear resistance is 3 times higher than that of similar steels. Most hydraulic valve manufacturers may know how to choose materials, but they may not do a good heat treatment.   2. On the equipment, AAK uses the Japanese NP520X-F full-automatic grinder to finish the valve spool. The surface of the processed valve spool is like a mirror with an accuracy of 0.8μm, the flexibility of the valve spool is improved by at least 2 times. Most hydraulic pressure control valve manufacturers can not process the same quality valve spool as AAK.   3. In terms of detection, AAK uses the German Diatest small pore diameter measuring instrument to check each valve hole of the hydraulic pressure control valve, and the measurement accuracy range can reach 0.1μm at least, ensure the concentricity of the valve hole is consistent, and most hydraulic valve manufacturers use random sampling inspection.   Davis privately told that the boss was very happy with AAK's help regardless of past grievances, and was also satisfied with Davis's ability to deal with unexpected problems.   AAK hydraulic pressure control valve has a performance of 2 million times of long service life. You can also have a small test! https://www.aakindustry.com/info-deta , il/hydraulic-pressure-control-valves- aak340

Some customer left a message to AAK: is AAK a hydraulic valve brand? I answered: AAK Hydraulic Valve has no plan to spend time on becoming a brand, but insist on working hard on building trust. The hydraulic components of small and medium-sized enterprises, whether they are hydraulic valves, coils, hydraulic valve blocks or hydraulic manifolds, are not brands in essence, but network trust. Hydraulic valve counterparts, don't be confused by the word "brand". Although many bosses really want to make a brand, they first encounter the hurdle of "trust". If they can't pass this hurdle, how can they get a brand? I always suggest that hydraulic valves should be made stronger rather than bigger. The guiding principle of brand building is to build trust, and only trust on the network. Don't think about the trust on the ground channel at all. Only the network can cover the whole world with the lowest cost. In a sense, as long as we insist on high-quality hydraulic valve content output every day, we can achieve global network trust. However, it is difficult to insist on writing the contents of hydraulic valves every day. What is more difficult is to write the contents of hydraulic valves that are "related to users" and "beneficial to users". There are too few people who are good at writing long and short essays. It's not that anyone who can write an article can write an essay. An article and an essay are two different things. Don't talk about essay. Even the title of an essay will embarrass 99% of the people. I saw the short video of the hydraulic valves made by my counterparts. I could only sigh. If you don't want the quality of the content, it's very simple to shoot the hydraulic valve video. You can pick up your mobile phone and say a few words of correct nonsense. Shout a few words “come and buy it”. Who can't, but is it useful? Anything done for the sake of doing is meaningless. It's difficult to be a brand of hydraulic valves. It's really difficult for small and medium-sized enterprises to be a brand. The first thing they encounter is the talent barrier. This barrier is not easy because you need to recruit 5 talents, not a worker. After passing the talent barrier, we also need to pass the hydraulic valve marketing barrier. The content should be planned. We should not write what we think and shoot what we think. The content is not systematic and cannot be played. For hydraulic valves, it is relatively simple to build network trust than to build brands. 5 knowledgeable personnel are in place, the content is well planned, and the promotion is carried out on a daily basis. Benchmarking the quality of international first-class brands, such as SUN, HAWE and HydraForce, to make the hydraulic valve manufacturing quality products. The devil of the product is always in the details. The details are all matters that require attention. There is an old saying in China that we should learn from time to time. Learn is practice. Deliberate practice is output. Only learning without output means understanding or knowing, but it is useless to understand and know. Only when you can do it can you really get it. In AAK Hydraulic Valve, whether you are the technician in the workshop, the QC of the production line, the gatekeeper of the procurement, the technical team or the sales team, we all insists on deliberate practice. We know what today, we know why, and we will know how tomorrow. All of them lay the foundation for trust. AAK Hydraulic Valve, only focus on quality and trust. https://www.aakindustry.com/info-det , ail/hydraulic-valves-aak339

Bahamonde is from Mexico and has cooperated with AAK on several non-standard hydraulic valves. At the beginning of this year, he was stuck by a hydraulic pressure control valve. A hydraulic crank-type lift developed by their company will appear at the exhibition in July. In order to get the test run successful as early as possible, Bahamonde found a local hydraulic pressure control valve manufacturer to make samples. The equipment commissioning was not smooth, and the fluid flow and pressure at the oil outlet of the hydraulic pressure control valve are unstable, resulting in inaccurate positioning of the hydraulic crank- type lift and unstable operation control. The original manufacturer said that the sample was based on the original design. Maybe there are defects in the original design. Bahamonde had contacted several local hydraulic valve manufacturers one after another, but none of them were willing to cooperate in redesigning the hydraulic pressure control valve and making samples. As the exhibition period was about to arrive, Bahamonde was very worried. Bahamonde thought of AAK because we had the experience of modifying their original design before. According to his hydraulic schematic diagram and the design of the original hydraulic pressure control valve, our engineers have a basic idea after discussing, but it takes time. Bahamonde told me that he could give me 50 days at most. After 3 times of design adjustment and 6 times of simulation, a new design scheme was determined. After 45 days, 30 samples of hydraulic pressure control valves were sent out. 2 weeks later, Bahamonde told me that the test was successful, and asked me to wait for the good news of their exhibition. Last week, Bahamonde placed an annual order of 1,200 hydraulic pressure control valves, and also mentioned that their hydraulic crank-type lift was very popular during the exhibition. Their engineers admire our technical team's brainy thinking. AAK made it successful this way: For this hydraulic pressure control valve, we changed the structure of the balance cone valve to the balance plunger type, which can let the pressure, connect the control working port and the pilot control port, control the fluid flow and pressure at the oil inlet, and conduct pilot control at the pilot port. At the same time, the hydraulic pressure control valve acts as the main stage of pressure control. The pilot flow of the valve is very small but the flow capacity is very strong, so the circuit design is flexible. And the newly designed hydraulic pressure control valve can integrate all pressure control circuits with external control functions, such as external control opening, external control closing, multi-stage pressure setting, etc., into the circuit, improving the stability of operation control. Most of the hydraulic valve manufacturers mainly produce standard parts and have no original design capacity. For the non-standard hydraulic valves, basically, they cross the river by feeling the stones. AAK hydraulic pressure control valve, accurate positioning and high stability, you can also try it! https://www.aakindustry.com/info-detail , /hydraulic-pressure-control-valves- aak338

A few days ago, there was a perplexing problem. A Russian customer who had cooperated for more than 5 years, confirmed an order for 1,600 hydraulic cartridge valves, but the payment had been always pending. This situation never happened. I was not in a good mood, and a bit frustrated. Today, I'm a little free. I want to think about the source of the sense of the lose. Of course, people will not have the sense of lose without reason. It must be something or someone that triggered my mood. At work, we usually focus on the person who triggers our emotions. There are several ways. One way is to settle him and let him follow our example, but it is usually impossible. Another way is to settle yourself. Go to find the source of this emotion, and then deal with it at this source, but it is difficult to completely deal with it. Suddenly I thought of a little story I saw the other day. A man was driving a boat in the river. There was another boat opposite him. He was about to crash into it. He shouted to go away. But no one on the opposite boat paid attention to him. He shouted again, but was still ignored. After crashed into it, when he was about to scold, he found that it was an empty ship and there was no one. What is the biggest inspiration of this little story? It shows me that this emotion is what I have originally, and others just ignite this emotion. For example, pain, happiness, joy, and sadness, these are the emotions that we originally have, or the emotions shared by the human collective. I have them, and you also have them. What we really experience is the feeling after these experiences. In fact, this feeling is also part of our work. We should be happy when we listen to the promise from others, but don't take it too seriously. The advantage of this is that you are grateful if the others kept the promise; You won't be too disappointed if the other broke the promise. The PO of the hydraulic cartridge valves was received but not paid. Maybe the customer had his difficulties. Happiness or sadness, it is the mode that has been set in the game of life. I can't stop the arrival of these emotions, nor can I stop their departure. We are just the hostels where these emotions temporarily reside. In this way, there may be no need to tangle, because the emotion itself will come and go. Speaking of this, there seems to be a little pessimism or inaction. Just lie flat and let your emotions come and go. How did I get out of the sense of the loss? If there is a bunch of carrots hanging in front of the donkey, the donkey wants to eat that carrot, but it doesn't seem to be able to eat it. In front of our work or life, there is also a bunch of carrots, it is the feeling of hope, also a source of happiness of our work and life. So the most important thing is not what the hope is, but to enjoy the feeling and have the feeling of hope. At this time, I understand the expectation AAK hydraulic cartridge valve brings to customers and the trust from customers behind it. AAK, a hydraulic cartridge valve manufacturer in China, has hope, has trust. https://www.aakindustry.com/info-detail/hy , draulic-cartridge-valve-manufacturer- aak500

This week, we’d like to introduce a hydraulic cartridge valve equivalent to HydraForce PRES50-30. It is a screw in, cartridge style, direct-acting, spool- type, hydraulic pressure reducing/relieving valve designed to act as a pressure regulating device for secondary circuits. It is intended for use in stable input flow circuits. Last June in 2022, a customer in Brazil found AAK when looking for a hydraulic cartridge valve manufacturer in China on Google. He was happy to found that AAK has the hydraulic pressure reducing/relieving valve equivalent to HydraForce PRES50-30. Before contacting AAK, he had checked with over 6 hydraulic cartridge valve manufacturers in Ningbo China, but none of them have any similar or equivalent model. This Brazilian customer ordered 10 pcs as the first order for testing. Last week, we were very happy to learn from the Brazilian customer that the E- PRES50-30 Pressure Reducing/Relieving Cartridge Valve shipped by AAK last June is still running very smoothly after 1 year, the quality is very stable. Next week, they will issue the official PO for a regular order of 500 pcs. AAK hydraulic pressure reducing/relieving cartridge valve E-PRES50-30 two advantages: 1. Pressure Rating 345 bar (5000 psi), benchmarking HydraForce 2. Its service life is 2 times that of its domestic peers Technical parameters of AAK E-PRES50-30 pressure reducing/relieving cartridge valve: Pressure Rating: 345 bar (5000 psi) Note: Port 3 137.9 bar (2000 psi) Note: Port 2 68.9 bar (1000 psi) Note: Port 1 Regulated pressure range: 31 to 55.2 bar (450 to 800 psi) Note: At 0.95 lpm (0.25 gpm) Flow Rating: 11.4 lpm (3 gpm) See Performance Chart Max.

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. AAK hydraulic needle valve, high precision, no jamming, you can also try it! https://www.aakindustry.com/info-detail , /hydraulic-needle-valves-aak337

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
