Master Zhang from hydraulic cartridge valve manufacturer AAK, we all like to call him Master. He comes from a grassroots background and worked in a mechanical factory after graduating from a technical school. He has been working at hydraulic cartridge valve manufacturer AAK for 9 years. He is almost 60 years old and doesn't talk much. He is responsible for equipment maintenance, repair report, and repair at hydraulic cartridge valve manufacturer AAK. He likes to walk around the workshop every day, whether it's imported equipment or domestically produced equipment, he always wants to tinker with it. To see which process has slow efficiency and low stability, ponder and see if we can optimize the equipment or add some auxiliary equipment. An old in a home is like a treasure of a family. This is also applicable to hydraulic cartridge valve manufacturer AAK. A few days ago, Bob from the UK sent a non-standard hydraulic pressure control valve sample to hydraulic cartridge valve manufacturer AAK. The sample provided by the original hydraulic cartridge valve manufacturer was approved by their engineers. However, the two batches of hydraulic pressure control valve shipments provided by the original manufacturer had unstable valve cage accuracy, which angered their engineers. They requested Bob to replace the hydraulic pressure control valve supplier. The shape of this hydraulic pressure control valve cage is complex, and the processing is also a bit difficult and time-consuming. Our workshop director is not very willing to take orders. Bob is very friendly to me and working with him is also enjoyable. I went to check with Master Zhang, and 2 hours later, he told me that the CNC machine tool upgraded 3 months ago can precisely treat this valve cage. With the direction given by the master, I told Bob to take a look at the video of how hydraulic cartridge valve manufacturer AAK processes the valve cages with the fully automatic production line, to see if he is still concerned about the unstable accuracy and if the processing time is in time. On the second day after receiving the video, Bob informed us via email that their engineers recognized hydraulic cartridge valve manufacturer AAK's valve cage production process, especially the automatic feeding process. The machining of the hydraulic pressure control valve cage adopts Jiachuan CNC machine tool and automatic feeding system, without the need for manual operation. This machine tool is skilled at processing complex shaped hydraulic pressure control valve cags, equipped with 11 knives. It can complete the processing of hydraulic pressure control valve cages in one go, from drilling, slotting, milling, boring, to threading. These 5 steps are automatically completed in one go, and feeding does not require manual labor. The entire bar is automatically imported, cut, and then imported into the machine tool fixture, and then the processing of the valve cage begins. The benefit of this operation is not only to improve production efficiency, but also to avoid positioning errors caused by human error, which may cause the instability of accuracy. Most hydraulic cartridge valve manufacturers first cut the material rod and then manually place the blank material into the machine tool fixture, which not only slows down production but also poses a risk of unstable accuracy. AAK hydraulic pressure control valve, even if it is a customized part, does not require technicians, you can also try it out!

Cleveland is from a Polish hydraulic equipment company. After 3 months of employment, he had trouble purchasing hydraulic cartridge counterbalance valves for the first time. At the beginning of this year, their client company customized a hydraulic transmission unit, which has high requirements about the hydraulic cartridge counterbalance valve in the lifting hydraulic circuit, and its function directly determines the transmission effect. Their engineer suggested purchasing SUN hydraulic cartridge counterbalance valves, but SUN hydraulics has no stock. Cleveland had to find a hydraulic cartridge counterbalance valve manufacturer to make samples. His colleague suggested a hydraulic cartridge counterbalance valve supplier that had cooperated with him for 4 years. That manufacturer was some hesitated, but was willing to try. During the commissioning, the hydraulic transmission unit was abnormal and the operation was unstable. This hydraulic cartridge counterbalance valve manufacturer had no solution. The engineer has been pushing for progress, and Cleveland, a novice, paniced. Cleveland tried to find the manufacturer of hydraulic cartridge counterbalance valves online, and found AAK on Google. He noticed that AAK had some customer cases about hydraulic cartridge counterbalance valves. He asked by email about the lead time for customizing the hydraulic cartridge counterbalance valve, and asked for benchmarking SUN valve. I felt that this is an inquiry with a real order. After communication, I learned that as a novice, he encountered difficulties and needed AAK's help. According to his drawing of hydraulic cartridge counterbalance valve, the internal structure is complex, and the accuracy is within 1μm. In particular, there are 6 requirements for coaxiality, and the sliding clearance of valve spool is very small. No wonder their engineer asked to purchase SUN hydraulic cartridge counterbalance valve. AAK was willing to sample, and was 90% confident. Cleveland was worried, but he believed me. After 60 days, AAK sent 10 hydraulic cartridge counterbalance valve samples. 3 weeks later, Cleveland sent an email of thanks. After AAK hydraulic cartridge counterbalance valve was installed in the hydraulic transmission unit, the commissioning was smooth, the engineer was satisfied, and the boss praised him. AAK hydraulic cartridge counterbalance valve is subject to strict manufacturing quality, function benchmarking SUN valve and performance benchmarking SUN valve, too. It is difficult to find the 3rd manufacturer of hydraulic cartridge counterbalance valve that can meet the following 3 points at the same time in Ningbo. 1. On the equipment, OKK ultra precision machine tool imported from Japan is used to produce this hydraulic cartridge counterbalance valve, and the machining accuracy can reach 0.01~0.3μm. Ensure that the coaxiality of 6 parts of each hydraulic cartridge counterbalance valve is completely consistent. 2. In terms of process control, AAK engineer follow up every processing link in the whole process, and constantly adjust the procedures until the accuracy reaches the standard. 3. In terms of detection, each hydraulic cartridge counterbalance valve hole and element shall be accurately measured with the German Diatest high-precision micro pore diameter measuring instrument and the three coordinate measuring instrument, and the minimum measurement accuracy range can reach 0.1μm. Ensure that the coaxiality of each element is consistent. AAK hydraulic cartridge counterbalance valve, dare to challenge high difficulty, you can also have a small try! https://www.aakindustry.com/info-detai , l/cartridge-counterbalance-valves-aak396

Yesterday, after 4 o'clock on Saturday, a classmate who had not seen me for 10 years called me and said he was staying in a five-star hotel in Ningbo. He invited me to dinner at the hotel tonight. What should I do? I asked two children, and the young child said, 'Of course you should go. When he arrives in Ningbo, how can you ask him to invite you to dinner? It should be you who invite him to dinner.'. The old child said there's no need to go. You haven't seen each other for 10 years, and no interaction in the daily life. Is there any significance in meeting? I remembered an interesting incident last month. Lam, a hydraulic cartridge valve customer from India, who purchased a small amount from hydraulic cartridge valve manufacturer AAK, mainly some hydraulic cartridge valves with high accuracy, suddenly called me and said that he had been in Ningbo for 2 days and was available at night. He asked me to come to his hotel and invite me to dinner. I didn't directly answer whether to go or not. First, I asked Lam about his itinerary to see if he had time. I could arrange a whole day to accompany him for a good stroll and treat him well. I could also invite him to visit the hydraulic cartridge valve manufacturer AAK. He seems to have only visited our factory once 7 years ago. But Lam said he will go back early tomorrow morning. At this point, I didn't have any interest in meeting him at the hotel either. If Lam agrees, it indicates that he cares about reuniting with hydraulic cartridge valve manufacturer AAK and is willing to pay a certain time cost. It also indicates that he truly cherishes the business relationship or friendship between hydraulic cartridge valve manufacturer AAK and him. My understanding at the time was that any customer visiting hydraulic cartridge valve manufacturer AAK should have made an appointment in advance. If it was temporary, it was likely that you were just a little extra fun for someone else's itinerary. Hydraulic cartridge valve manufacturer AAK was not willing to be such a candidate. Business has always been a two-way flow, and if one doesn't think twice in business, hydraulic cartridge valve manufacturers become a dispensable embellishment in others' business. What is seen in business is also compared in life. If a classmate who has not seen you for many years has feelings, he will attach great importance to this meeting and bring a gift, at least to visit your family. If he asked you to go to his hotel and claimed to invite you to dinner, it's just to show off to you, he's doing better. Some people are even funnier when they claim to be in their location (the 5-star hotel they are staying in) while you rush to pay the bill. This kind of party just helps the other party's Superiority complex and makes the other party look down on you even more. At this time, the money spent has no meaning at all, it just adds a bit of fun to him. After he left, he had no contact with you anymore, and he returned to being a zombie in your WeChat account. I replied to this classmate that I haven't seen in 10 years by asking if he has time. I will arrange a special day to accompany him on a good tour of Ningbo and treat him well. If he agrees, it means he is willing to reunite this time and cherishes our friendship. As a result, he said he didn't have time, but I was willing to give him another chance. He didn't need to invite me to eat at his 5-star hotel. I came to meet him and invite him to taste Ningbo's unique cuisine, which is about half an hour's drive from his hotel. He still said that the weather is too hot and he doesn't want to make trouble. I told him directly: I'm sorry this time. Since you're so busy, we can only talk again next time! Next time, it's best to make an appointment with me or leave some more time for us to get together well. Hydraulic cartridge valve manufacturer AAK, keeps a clear head in life and does not make small actions under the table in business.

Over the past year, Jerome has purchased more than 20 batches of different types of hydraulic valves of test orders from more than 10 hydraulic valve manufacturers in Ningbo, including AAK. Finally, he chose to place the large order of hydraulic flow control valves with AAK, because the packaging details of AAK made him think that the quality of AAK hydraulic flow control valves is the most reliable. Jerome is from a hydraulic equipment company in Italy. He sent an email last week to purchase 2,500 hydraulic flow control valves. I was surprised because Jerome always purchased small orders before. After e-mail communication, it was learned that Jerome has purchased more than 20 batches of different types of hydraulic valve test orders from more than 10 hydraulic valve manufacturers in Ningbo in the past year. There are always some problems, such as time delay and communication delay, especially the packaging of the test order was criticized by his boss. The quality defect of the hydraulic flow control valves purchased last time was complained to the boss by the company's installation engineer. During the assembly process, the installation engineer found that several hydraulic flow control valves could not be screwed into the socket at all, mainly due to obvious bumps at the threads of the hydraulic flow control valves. Jerome requires the original hydraulic flow control valves to be replaced. The manufacturer believes that each hydraulic flow control valve has been pressure tested before leaving the factory and shipped only after it is qualified. The bump was caused by the carelessness of their installers. The installer showed the boss of the damaged package photos to reveal the reason. Some of the packing boxes of the hydraulic flow control valves are deformed, some are broken, and even some of the inner packing poly bags are broken. Those hydraulic flow control valves with bumps were improperly packaged and protected during transportation. Jerome is helpless because of the factory's prevarication. Fortunately, this is just a trial order. Jerome thought of the packaging details of each trial order of AAK. Only the packaging of AAK was different from that of other hydraulic valve manufacturers in Ningbo. At that time, it was only the trial order that he didn't pay attention to the packaging details of AAK. Now he saw the problems caused by improper packaging during transportation from other hydraulic valve manufacturers. He realized that only each trial order of AAK, the packaging received was intact. Later, I told him that because the quantity of trial orders was small, most of them were delivered by express, and it is unavoidable that the parcels will be bumped. AAK will inspect each hydraulic flow control valve separately when leaving the factory. Only the qualified hydraulic flow control valves are put into the bubble bag and then into the corrugated box with the right size, so that there is no extra room for the hydraulic flow control valves to move in the inner package. Then put several small cartons into customized 5-layer corrugated cartons, so that there is no extra space around, which can not only save the transportation cost of customers, but also avoid the collision of hydraulic flow control valves during the transportation. Then, the outer box is reinforced with herringbone packing belt, and pasted with the mark of fragile and handle with care to remind the express personnel. For express delivery exceeding 10kgs, wooden boxes are used for protection. Usually, it is difficult for peers to think of these small details in the packaging of the trial order, and AAK has always pay attention to even the small details of all links of the hydraulic flow control valves. AAK hydraulic flow control valves, care about every small detail, you are welcome to give it a try! https://www.aakindustry.com/info-detai , l/hydraulic-flow-control-valves-aak177

Over the past 2 years, Peter, who is from ST hydraulic equipment manufacturing company, has been very smooth in purchasing hydraulic valves in Ningbo. He and I often have some communication via emails, but there is no cooperation yet due to the high price. A batch of hydraulic directional control valves he purchased last year had problems. Six months after shipment, the customer found that the hydraulic system could not operate because the valve spool of the hydraulic directional control valve was stuck, and asked ST company to solve it within 30 days. Peter communicated with the original manufacturer of this hydraulic directional control valve but no gain. The manufacturer thought that the hydraulic oil was not clean or there were problems in installation, because their hydraulic directional control valves passed the test before shipping. The boss asked Peter to check with other manufacturers and be sure to solve customer complaints within 30 days. Most manufacturers advised that they have no existing stocks that are exactly same as this hydraulic directional control valve, and they are also not willing to produce it especially for such a small quantity. Some manufacturer advised that they can customize it for Peter, but it will take more than 50 days and also costs a lot. Two weeks passed but still no solution, which makes Peter haggard. Peter thought of AAK and emailed us to ask if there was a hydraulic directional control valve of the same model, and the faster the delivery, the better. After reading this email, I understood that there was a problem with the hydraulic directional control valves purchased by Peter. After further communication, I learned that the valve spool of the hydraulic directional control valve he purchased this time was easy to be stuck and complained by customer. According to Peter's drawings and working condition requirements, AAK engineers conducted comparative analysis, and later found that the control principle and size of this hydraulic directional control valve are consistent with one of AAK's existing stock, except that the design method is different. I immediately answered Peter that AAK had 100 hydraulic directional control valves in stock. At the same time, I emailed the drawings of AAK hydraulic directional control valves and asked Peter and his engineers to verify whether AAK hydraulic directional control valves met their requirements. The next day, Peter said that their engineers thought AAK hydraulic directional control valve could not be used because some designs were fundamentally inconsistent. I suggested to him: if you want to solve the customer complaint within 30 days, perhaps purchasing this hydraulic directional control valve is the best choice. To believe in the analytical ability of AAK, you should try our hydraulic directional control valves first. If it really cannot be used, AAK shall bear all expenses for goods return. Peter has no choice and asked AAK to send 24 hydraulic directional control valves. A week later, Peter said that the hydraulic directional control valves sent by AAK was not only easy to install, but also fully met the working requirements of their company's hydraulic equipment. Their engineers said twice in a row: incredible, incredible. His customer is very satisfied with this quick after- sales. Peter spent 2 weeks looking for the hydraulic directional control valves, but no gain. Why did AAK finish it 1 week after analysis? That's because: AAK hydraulic directional control valve has two absolute advantages and has already surpassed its domestic counterparts: 1. AAK has a high-precision CNC machining center imported from Switzerland and various independent fixtures upgraded and refitted by itself, which eliminates human errors and avoids valve spool stuck and other faults. 2. The independent professional R & D team, combined with unique R & D technology, has realized the personalized customization demand of hydraulic directional control valve, which can not be achieved by 95% of domestic peers in China. Peter told me privately that his boss asked him to send samples of their other hydraulic directional control valves previously purchased elsewhere to AAK for quotation. Even if the price is a little expensive, they should still choose more stable hydraulic valves from AAK. They not only admire AAK professional analysis ability, but also AAK ability to solve difficulties for customers in time. AAK hydraulic directional control valve is professional and attentive. It can solve problems for you in time. You can also have a small try. https://www.aakindustry.com/info-detai , l/hydraulic-directional-control-valves- aak176

AAK introduced HARDINGE precision CNC lathe, and the machining surface accuracy of hydraulic relief valves was improved to 0.3μm, which can not be reached by nearly 95% of hydraulic valve manufacturers in Ningbo. After comparing the parameters of different factories, a German customer found that only AAK meets their requirements for PO confirmation. Fred, a hydraulic valve purchaser from Brandenburg, Germany, is in urgent need of purchasing a hydraulic relief valve for a forklift recently. This hydraulic relief valve has a very high precision requirement. The machining surface roughness of conventional valve is generally around 0.8μm, but this one needs to reach 0.3μm, the precision of which is nearly 3 times higher. Fred contacted all his hydraulic relief valve manufacturers, but none of them could achieve an accuracy of 0.3μm. It is difficult for Fred to find a solution. Fred decided to try through B2B. He contacted nearly 10 hydraulic relief valve manufacturers online. Two said they could try it, but they are not sure for 100% success, because they had never made such a high-precision hydraulic relief valve. It seems that Fred has no good choice and asked them to try samples. Three weeks later, due to the insufficient accuracy and stability of the hydraulic relief valve, the customer did not approve the samples from these two manufacturers and asked Fred to re-proofing. Fred had to find other new manufacturers of hydraulic relief valves. Fred saw AAK hydraulic valve on B2B and left a message on our website (www.aakindustry.com): can you make the hydraulic relief valves with accuracy of 0.3μm? I noticed that he browsed AAK website for about half an hour. He should have encountered problem on accuracy. We reply that it depends on the parameter index of the hydraulic relief valve and the working condition requirements. After receiving his drawing, our engineer confirmed that we can reach the accuracy of 0.3μm of this hydraulic relief valve and there may be no 3rd factory who can meet this requirement in Ningbo. If any doubt, we can make samples to test directly. Fred accepted AAK suggestion and paid a sample fee of $1,300.00. Two weeks later, AAK sent the samples of the hydraulic relief valve. After testing, Fred informed that AAK hydraulic relief valve was praised by the customer. Not only did the accuracy of the machined surface meet the standard, but the upper and lower deviation was also very small. While the samples of hydraulic relief valve from last two manufacturers are not stable, some with 0.3μm, some with 0.4μm, or even 0.6μm. Only after comparison, the customer realized that AAK hydraulic relief valve is really high precision, so they have to admire it. The roughness accuracy of the machined surface within 0.3μm is always the hard index of AAK. We have introduced the American HARDINGE precision CNC lathe, which gives us the most powerful support in terms of accuracy. The spindle speed of the machine tool is up to 6000r/min, the radial runout of the spindle ≤ 0.0008mm, the positioning accuracy (X/Z) ≤ 0.005mm/0.008mm, the repeated positioning accuracy (X/Z) ≤ 0.003mm/0.005mm, and the roughness of the machined surface Ra ≤ 0.3μm. Turning roundness ≤ 0.4μm. Turning cylindricity ≤ 0.1μm. At the same time, we upgraded its fixture, with large clamping area and stable processing. Although there are no 2 identical leaves in the forest, there are 2 hydraulic relief valves with the same precision in AAK. AAK hydraulic relief valve with accuracy up to 0.3μm, you can also have a small try! https://www.aakindustry.com/info-detai , l/hydraulic-relief-valves-aak175

Hogan is from Germany. In the past year, he has made 3 purchases from hydraulic cartridge valve manufacturer AAK. Recently, Hogan emailed us to ask if AAK can customize a hydraulic directional cartridge valve with spool accuracy within 2μm. The 2μm valve spool should not be difficult. I don't think the problem will be so simple, and didn't agree rashly. After further investigation, it was found that the hydraulic direction cartridge valve produced by the original hydraulic cartridge valve manufacturer had no problem to meet the spool accuracy during sample testing period. However, there was an accuracy deviation in the shipment of 360 pcs of hydraulic directional cartridge valves, which means a problem with the quality stability of the original hydraulic cartridge valve manufacturer. The boss was not satisfied with his purchase this time, which put a lot of pressure on Hogan. According to the hydraulic directional cartridge valve drawing sent by Hogan, the valve spool is smaller than the conventional one. 5 days later, we also received samples of hydraulic directional cartridge valves from the original manufacturer. Excluding the single problem of unstable precision of the valve spool, the overall manufacturing quality is actually good, whether material selection or appearance, which also indicates that Hogan is professional in choosing a hydraulic cartridge valve manufacturer. According to Hogan's understanding of the original hydraulic cartridge valve manufacturer, their precision machining equipment is not inferior. I think the reason is that the positioning is not precise enough, which requires the experience of technicians. We have also stumbled in this area before. So we found a way to eliminate manual involvement and upgraded the automatic CNC cylindrical grinder from Japan. From picking up, placing, to positioning, we relied on computer program control to avoid human errors. Hogan asked us to shoot a video of this fully automatic equipment to compare with the processing production line of the original hydraulic cartridge valve manufacturer for the hydraulic directional cartridge valve spool. From the video, we can see that the fully automatic CNC cylindrical grinding machine imported from Japan adopts the unique high rigidity dynamic pressure bearing of Tsugami, which has strong stability and high precision. The V- flat guide surface structure ensures the stability of the hydraulic direction cartridge valve spool accuracy in the precision machining process. As long as the positioning of the valve spool is accurate before machining, there will be no problem for the accuracy to be stable and within 2μm. How does AAK avoid human error in valve spool positioning? Hydraulic cartridge valve manufacturer AAK equipped this equipment with a dedicated fully automatic robotic arm, which is integrated into the same system as the grinding machine. After the equipment is started, the fully automatic robotic arm starts working first, automatically clamping the valve spool and feeding it into the fixture. The valve spool is automatically clamped and precision machining begins. After processing, the robotic arm clamps out the valve spool. The entire production process does not require the involvement of technicians. 3 days after Hogan received our video, he directly sent the PO for 360 pcs of hydraulic directional cartridge valves that had problems with the original hydraulic cartridge valve manufacturer. AAK hydraulic directional cartridge valve, customizable, with stable accuracy, you can also try it out!

Ephraim comes from a hydraulic equipment manufacturing company in Chile. He has been purchasing smoothly for 3 years. Unexpectedly, the hydraulic cartridge relief valve purchased at the beginning of the year stumped him. 3 months ago, they received a customer complaint that the hydraulic cartridge relief valve on the logistics transmission system of the coal yard could not be opened or closed properly, or the control was unstable. After checking, it was found that the damping hole and the slender hole of the valve cage were blocked by impurities in the hydraulic oil. 3 months after the hydraulic oil was replaced, the old problem reoccurred. The original manufacturer of the hydraulic cartridge relief valve said that the site was too dirty. The problem was not avoidable. The only solution was to replace the hydraulic cartridge relief valves regularly. The boss couldn't accept this so frequent after-sales service and asked Ephraim to solve the problem from the root. After browsing AAK website, Ephraim found that AAK had many cases of solving customers' difficult problems, and sent an email to ask: how to improve the hydraulic cartridge relief valve to reduce the blockage of the conveying equipment in the coal yard? I didn't think he explained it clearly. After communication, I learned that the damping hole of the valve and the slender hole of the valve cage were easily blocked by impurities in the hydraulic oil. According to the anatomical picture of the original hydraulic cartridge relief valve provided by him, its damping hole and slender hole structure are a bit strange. If optimized, the anti pollution ability can be improved. Ephraim was half convinced when he learned about this solution. After 40 days, AAK sent 18 hydraulic cartridge relief valve samples. Ephraim sent an email last week for an order of 200 hydraulic cartridge relief valves. He said that AAK hydraulic cartridge relief valves have been used for 6 months, there was no blockage. Their boss wanted to replace all the equipment with AAK relief valves at one time, completely saying goodbye to the strange circle of after-sales service once every three months. AAK hydraulic cartridge relief valve is unblocked. The key lies in the improved structure of the original hydraulic cartridge relief valve from 3 points: 1. The valve seat of the hydraulic cartridge relief valve is a cylinder with one end open and one end closed. The open end of the valve seat is equipped with external threads. Two springs and spring covers are installed in the valve seat in sequence. The first spring is a conical spring with the big end upward, and the second spring is a cylindrical spring. 2. The upper end of the valve stem is fixedly connected to the spring cover, the lower end of the valve stem is provided with an overflow valve spool, and the lower end of the second spring is installed in the spring seat. 3. An oil make-up valve spool with an overflow valve port is arranged below the spring seat. An oil port is arranged between the oil make-up valve spool and the spring seat, the valve rod passes through the overflow valve port, and the dynamic seal of the overflow valve spool is matched at the bottom of the overflow valve port. The oil make-up valve spool and spring seat are of an integrated structure. The sealing surface of the oil make-up valve spool is a spherical sealing surface, and the sealing surface of the overflow valve spool is a conical sealing surface. The optimized AAK hydraulic cartridge relief valve eliminates the previous damping holes and slender holes, reducing the number of seals. The sealing surface adopts the structure of combination of conical surface and spherical surface, which is better for sealing and assembly. AAK hydraulic cartridge relief valve, no blockage, you can also have a small try! https://www.aakindustry.com/info-d , etail/relief-valves-aak460

Last month, we tweeted: “A young couple who have already been engaged taught me a lesson, AAK equates the business of integrating hydraulic cartridge valves with marriage”, some people say they don't understand. What kind of romantic approach should be used to treat new customers of hydraulic cartridge valve manufacturers? This is a good question. Unmarried girls must understand a common sense: a man showing kindness to you does not mean a man wants to marry you. You posted a refined selfie on your friend circle, and many boys were commenting: Ah, how beautiful! If you mistakenly think there are many pursuers, then you think too much. When it comes to dating, you may have a lot of partners, but when you mention getting married and want to execute it, the guys who sweetly talk to you are gone. This is actually similar to the hydraulic cartridge valve manufacturer in their daily communication with new customers, as their logic is the same. All hydraulic cartridge valve manufacturers, facing numerous new customers (without any business yet), must understand a common sense of business: customer inquiry does not mean placing an order with you. Hydraulic cartridge valve manufacturers have released new products on Google, and some potential hydraulic cartridge valve customers are leaving messages asking about hydraulic cartridge valve parameters and prices. If hydraulic cartridge valve manufacturers think that there are many customers who want this new product, it is because hydraulic cartridge valve manufacturers are thinking too much. For new products, there may be many inquiries, but few actual orders are placed. The truth of love in life is that men get married more realistically than women, and they weigh the pros and cons rather than just considering emotions. In business, the truth of placing an order is that customers place orders more realistically than hydraulic cartridge valve manufacturers. Customers will compare their manufacturing quality with other manufacturers, rather than just considering price. In life, when getting married, they care more about whether the woman will make a living than whether she looks beautiful. You will find that the wives of wealthy people are mostly not super beautiful women. 99% of boys with good conditions who find wives will receive high recognition from their parents. Parents looking for their daughter-in-law are considering whether this woman is a person who lives a life, or if her family background can help their son? The girl is beautiful, has a good job, and earns a lot of money... In the eyes of the male parent, it is not an added bonus. These so-called good personal conditions will not help your marriage. In business, when placing an order, customers are more concerned about whether the product can bring them benefits and whether the hydraulic cartridge valve manufacturer has gained the trust of the customers, rather than the price. AAK, for each new product, the first is to ask yourself 3 questions: 1. The additional benefits that AAK hydraulic cartridge valve brings to customers. 2. The invisible benefits that AAK hydraulic cartridge valve brings to customers. 3. AAK advantages that cannot be provided by hydraulic cartridge valve manufacturers in the same industry A woman's flowering season is only a few years, and age is always the Achilles heel. Although there are many manufacturers of hydraulic cartridge valves, trust is always a hard nut to crack.

Yesterday morning, a colleague complained to me that he couldn't stand the Indian hydraulic valve customer. After communication, I learned that this old customer had to bargain every time when he placed the reorders, and he had asked for price reduction for 3 times. This time, this colleague couldn't bear it. There is an old Chinese saying that there is no need to bear it anymore. It seems to explain the legitimacy of the actions: I can't stand it. I have to do so. In fact, what you do when you can't bear it, whether it's right or wrong, good or bad, you shouldn't do it. What is the goal of AAK hydraulic valve? Isn't there more and more choice in the hydraulic valve industry? Specific to everyone of AAK hydraulic valve is to avoid making themselves have no choice. To be unbearable is to admit that you have fallen into a state of no choice. Think about my colleague carefully. Why didn't he have a choice? People often ask: is effort more important or choice more important? It is said that when you have a choice, choice is more important. If my colleague can insist on marketing like other colleagues and has more than 3 old customers of hydraulic valves, is there a better choice? And when you have no choice, hard work is important. In terms of specialty, adhere to the output of professional contents in hydraulic valve, and move towards the direction of technology and process; In terms of service, stick to the direction of trust. Combine the two, you don't need to worry about having no choice. In fact, there is another extension of this answer, that is, what is the purpose of efforts? Just to make yourself more selective. What is the AAK hydraulic valve effort for? In order to make ourselves have more choices to do a good job of hydraulic valves. AAK hydraulic valve adheres to the choice of subdivided target customers, and serves customers well with AAK hydraulic valve's distinctive advantages or distinctive technical features. AAK hydraulic valve adheres to a group of people, a lifetime and one thing, so that each user can make good use of AAK hydraulic valve. AAK hydraulic valve adheres to the principle of integrity, does a good job in the business of AAK hydraulic valve, and sincerely treats every customer who purchases hydraulic valves from AAK. Let more customers use good hydraulic valves with real materials without wasting money. I told my colleague that you should treat the client as your girlfriend. For example, she offered to break up with you today, and you gave her your last speech. If she understands your mind, she will come back. If she doesn't come back, it means she's not suitable for you. He sent an email to the Indian hydraulic valve customer: when you asked a price reduction of this hydraulic valve for the first time, and I gave you 5%. AAK treats the quotation of each hydraulic valve in good faith, and does not falsely quote the price, and does not arbitrarily quote the price, which is an expression of dishonesty in itself. For the second time you reduced the price of this hydraulic valve, I gave you 2%. This 2% is my business commission, that is to say, for the second order of hydraulic valves, I serve you free of charge. I gave you another 2% of your third hydraulic valve order. I told the finance that I would pay for the 2% price difference myself, because I had to complete the annual business key performance indicators (KPI). Your 4th order of hydraulic valve will cut my price again. I not only don't earn a penny, but also pay for the keeping of an unprofitable business. I have to eat, too. I have no food to eat. How can I serve you? I hope you can take care of me to eat, so I have the confidence to serve you well. Surprisingly, today, this Indian hydraulic valve customer placed an order at the original first price. AAK hydraulic valve is not only different, but also miracles. You can also have a try. https://www.aakindustry.com/info-detai , l/hydraulic-valves-aak174

On the first day of March, Chris from an industrial solar energy company in the United States sent an inquiry about the hydraulic check valves. This is the first email from Chris to AAK. I'm not sure where she learned about AAK and got the email address. After further communication, we knew that she wanted to purchase total 1,100 hydraulic check valves of two styles. The next day, she sent the detailed drawings and working condition requirements of the hydraulic check valves to be purchased. Chris needed us to quote urgently. She has contacted many hydraulic check valve manufacturers, but the lead time can not meet her requirements, she hoped that AAK hydraulic valve can ship as soon as possible. AAK engineer analyzed her hydraulic check valve drawings and working condition requirements, and soon matched the production procedure in AAK database. Coincidentally, this is the same as the hydraulic check valve purchased by one of our Indian customers, but only the sealing ring is different. Every time, the Indian customer always needs goods urgently, and the quantity is sometime large and sometime small, so we often produce some flexible stocks to meet the immediate demand of this Indian customer. After receiving her hydraulic check valve drawings and working condition requirements, AAK offered the price and 7-day delivery time on the same day. Unexpectedly, Chris sent us the bank slip for the full payment. In addition to surprise, we realized that this customer were in urgent need of this batch of hydraulic check valves. We arranged to send approval samples immediately, but the customer said that it was not necessary to send the samples for approval, because the drawing parameters of the hydraulic check valve provided by AAK were consistent with their needs. She hoped that we can change the sealing rings and air freight the goods via TNT as soon as possible at her expense. It is our principle that if customers treat us with A, we will reward them with A + +. Our workshop organized people to replace the sealing rings of hydraulic check valves immediately, and purchased the master cartons as soon as possible, and shipped it in 3 days. When we sent the shipping photos and airway bill of the hydraulic check valves to the customer, she used 3 thanks to end the purchasing of the hydraulic check valves. Without seeing the samples, but advance the full payment directly when quote is just received, which is the first time I met. Although it is only a small order of more than 5,000 US dollars, behind it is the customer's trust in AAK hydraulic valve. In this era, the most expensive thing is not gold and diamonds, but trust. Once the problem of trust is solved, business is a natural thing. All things that can enhance trust should be done more and desperately, which is what AAK hydraulic valve has always insisted on doing. If you do something to enhance trust, you don't worry about having no customers. AAK hydraulic valve builds confidence in good times and combs quality in bad times. The more we face uncertainty, the more we should insist on doing the right thing and try our best to enhance trust. AAK hydraulic check valve is not only fast, but also stable. You are welcome to give it a try https://www.aakindustry.com/info-detail , /hydraulic-check-valves-aak173

This week, we’d like to introduce a Hydraulic Screw-in Counterbalance Valve equivalent to SUN standard part CBGG. The counterbalance valves with pilot assist are meant to control an overrunning load. The check valve allows free flow from the directional valve (port 2) to the load (port 1) while a direct-acting, pilot-assisted relief valve controls flow from port 1 to port 2. Pilot assist at port 3 lowers the effective setting of the relief valve at a rate determined by the pilot ratio. A customer in Spain sent us inquiry for this counterbalance valve last September, with annual qty of 600 pcs. However, after we quoted the price, there was no any feedback. The customer sent us inquires for other SUN cartridge valves at later times. Every time, there was no any feedback. Unexpectedly, this March, the customer got back to us and placed the trial order of 10 pcs for CBGG. Until that time, we learned that AAK prices were 5% - 10% higher than other hydraulic cartridge valve manufacturers in China every time, so he placed the orders with other manufacturers. However, the quality of hydraulic cartridge valves he purchased from other hydraulic cartridge valve manufacturers in Ningbo was not stable, he was very frustrated, so he wanted to test AAK quality. We delivered the 10 pcs of test samples. Last week, we were very happy to learn that AAK samples passed the testing. They are still performing very well after 9 months of use. The customer placed their annual order with AAK finally. It has been 15 months since we received the inquiry for this counterbalance valve CBGG. AAK hydraulic counterbalance valve 2 advantages: 1.
