Two Advantages for Salesperson of Hydraulic Manifold Manufacturers

There is an old Chinese saying “Good wine needs no bush”. The meaning is that my product is very good and I am not afraid that no one will buy it. This saying is a bit out of place now. For hydraulic manifold manufacturers, if your quality is stable but without any dissemination, no customer knows where your hydraulic manifold manufacturer is. Some hydraulic manifold manufacturers know that their quality is average, and their sales concepts are that relationships and lower prices can make up for it. Such sales concepts are not beneficial for both hydraulic manifold manufacturers and customers. For a hydraulic manifold manufacturer, how can be good salesperson, or what are the advantages that good salesperson should have? I learned from a small story that a good salesperson needs to have curiosity and participation. A sales representative of an airline, his major client gave him an inquiry. Tomorrow afternoon at 4 o'clock, 20 people from the client company will rush to Beijing for a meeting. They will be flying on the same plane, with a model requirement of 787. Everyone needs a seat on the aisle side, and each person will have an additional fruit meal. The budget cannot exceed 800 yuan. The first reaction of the salesperson was that they couldn't accept this order because their airline had a 380 model and didn't have a 787 model. An hour later, the salesperson was curious about why the customer insists on the Boeing 787, so he communicated with the customer. The customer said it was a large airplane, so the salesperson sent him photos of the cabin of their Airbus 380 model, and asked the client, ’Is it such a large airplane?’ The customer said yes. The salesperson is motivated, following closely with the second question, ‘why do 20 people have to sit on the same plane?’ The customer said it's convenient to be together, but the salesperson said that there are 20 people sitting on the same plane in the same company. From a risk perspective, it is possible, but from a probability perspective, it is almost non-existent. However, let's be more meticulous in our work and minimize the risk as much as possible. In case the boss is concerned with details. The customer said, it makes sense, listen to you. This salesperson was curious and actively involved, reaching a consensus with the buyer and landing the order. Buyers send inquiries to hydraulic manifold manufacturers, and there are many different roles for buyers, some are bosses, some are engineers, and some are just purchasers. Especially or a purchaser, his execution of the company's procurement work is based on personal consciousness. For example, in the story above, why do all people need a seat on aisle side? I think it's so comfortable, but in fact, among the 20 people, some prefer to lean against the window. The salesperson of hydraulic manifold manufacturers should be driven by curiosity, understand why customers have this requirement, communicate with customers, express concern, translate their "I think" into details, be understanding, and participate. Even if there is a budget conflict, there is still a possibility of increasing the budget. What's really important when flying to a meeting is to be on time. In order to arrive on time, there is a possibility of increasing the budget. Sometimes what buyers want is not necessarily cheap, it may be a sense of presence, security, achievement, or taking advantage of. If you want to satisfy their feeling of taking advantage with cheap, no matter how cheap you are, it cannot dispel the buyer's "I think". Customers always hope to get more and give less. If we treat the buyer's stated needs as real needs without considering their personal cognition, then this communication cannot reach the point, where all needs are executed through people. Without understanding the other party, it is difficult to have in-depth communication. The 2 common points of good salesperson for hydraulic manifold manufacturers are curiosity and participation, which need to keep up. Only by following up can there be a chance. Finding the truth about the problem and solving it requires resources. Resources are not what you need to have, but what the customers that you serve need. No matter what kind of customer, they are all role aware in an objective environment, and their needs are determined by their role. There are 2 types of resources: one is called heavy resources, which hydraulic manifold manufacturers can directly help customers achieve, and the other is called light resources, which hydraulic manifold manufacturers can help customers know how to achieve. However, this is lacking for the salesperson of most hydraulic manifold manufacturers. To express concern, interact with customers, and utilize your heavy resources to inspire your light resources. This kind of salesperson is what hydraulic manifold manufacturers and customers need.

AAK development of Hydraulic Relief Valve for Aerospace equipment

Some time ago, an old customer in the United States needed us to sign a confidentiality agreement to develop a new hydraulic relief valve. The drawings of the hydraulic relief valve were sent 1 month after the confidentiality agreement was signed. The customer requested that if we were not able to develop it, they would witness us destroy the drawings and documents of the hydraulic relief valve by video. It's the first time for this customer to be so formal. After receiving the drawings of hydraulic relief valve, we knew that it was to match with a set of aerospace equipment developed by a world top 500 enterprise in the United States. AAK engineers reviewed the drawings for 3 days and still didn't write the sample program. This hydraulic relief valve is not only small in size, but also has material requirements, machining accuracy requirements and use frequency requirements that exceed the parameter requirements of the hydraulic relief valves we have seen. We estimated that the overall development cost will not be less than 20,000 US dollars, and the success rate will be about 10%. When we mentioned the development cost and difficulty to the customer, the customer's answer is: now I'll give you 30,000 dollars and give you 1 year of time. If the development is successful, you can wait for the order of hydraulic relief valve. If the development fails, this $30,000 will be deducted from the payment for AAK in the future. That’s to say that the customer will prepay for the development cost of the hydraulic relief valve, but if it fails, we will need to refund it by deducting from the future payment gradually. I did not hesitate to reply to the email and was willing to try to develop this hydraulic relief valve. Our engineer joked that next, it is estimated that he will lose a layer of skin. If it fails, it may be not only a waste of tens of thousands of dollars in development costs, but also the loss of his own job. I told him that the success of the hydraulic relief valve development would be counted as the contribution of the technical team, and the failure would be counted as mine, because I can't fail to live up to the customer's support for our development. Some people in AAK can not understand how this could be a kind of support. Maybe he didn't think about a question, that is, what would the mentality of the technical team be without customer support? Behind these are two completely different ways of thinking. One is that if you haven't done it yet, think about failure first, think about whether there is a bottom plan first, and if not, don't do it. There is also a way of thinking, which is to think about how to start first. If conditions permit, start working first. The difference between these two ways of thinking is not just the difference between conservative and radical, but whether people are the key factor to create value. With the starting money, the hard work of the technical team and the best logistics support of AAK, the probability of successful development of hydraulic relief valve may be high. AAK hydraulic relief valve, no matter how difficult it is, just do it first. You are welcome to give it a try. https://www.aakindustry.com/info-detail/hy , draulic-relief-valve-aak179

AAK Hydraulic Cartridge Pressure Control Valve with 3 Unique Structures

Divyesh is from a hydraulic equipment manufacturing company in Pakistan, and has 3 years of procurement experience smoothly. In the second half of last year, their ultra-high pressure forging press was complained by customers that the equipment was shaking. After checking, it was found that the hydraulic cartridge pressure control valve was abnormal and difficult to adjust the pressure, resulting in large system pressure fluctuations and equipment jitter. The original manufacturer of the hydraulic cartridge pressure control valve tried to improve it, but the effect was general. The trouble was that there were more and more similar complaints. Divyesh had a very big headache. Divyesh found AAK on Google and stayed on AAK hydraulic valve website for more than 10 minutes. Perhaps AAK customer cases of optimizing the hydraulic valve stimulated him and he sent us an email asking: 1. Can AAK make the pressure adjustment of hydraulic cartridge pressure control valve convenient? 2. How does AAK control the pressure fluctuation of hydraulic cartridge pressure control valves? 3. How long does AAK need to optimize the original hydraulic cartridge pressure control valve? After communication, I learned about Divyesh's dilemma. According to his original drawings and the schematic diagram of the hydraulic system of the ultra-high pressure forging press, AAK engineers found that the problem could be solved by optimizing the structure of the original hydraulic cartridge pressure control valve. After 35 days, AAK sent 12 samples of hydraulic cartridge pressure control valves. 3 months later, Divyesh informed by email that AAK hydraulic cartridge pressure control valve had been used for 3 months, the customer had no complaints about the forging press shaking. AAK hydraulic cartridge pressure control valve has stable pressure control and convenient pressure regulation, and their engineers are very satisfied. AAK hydraulic cartridge pressure control valve is mainly composed of valve body, booster valve spool, external control valve spool and spring. Our engineers have made 3 unique structures for the original hydraulic cartridge pressure control valve, which most hydraulic cartridge valve manufacturers may not expect. 1. The booster valve spool is T-shaped, and the area of one end connected with the spring is twice that of the lower end. The valve spool is equipped with a damping hole extending from the load end to the spring end. The internal pressure on one side of the spring is lower than the inlet pressure, that is, a smaller pressure is used to control a larger pressure, which plays the role of boosting, and the pressure adjustment is convenient. 2. The external control valve spool is connected by a pipeline at one side of the spring. The valve spool is I-shaped and is equipped with a T-shaped damping hole, which can make the oil in the compression part press out of the valve body, effectively maintaining the stability of the external control valve spool. 3. On the same side of the valve body of the hydraulic cartridge pressure control valve, there are oil inlet holes and oil outlet holes. The oil inlet holes are connected through pipelines. The valve body is equipped with a connection hole at the end of the oil outlet hole. When the load oil pressure is too large, the upper limit of the oil pressure balance can be carried out to meet the working condition requirements under ultra-high pressure. AAK hydraulic cartridge pressure control valve, high pressure and large flow are also stable, you can also have a small try! https://www.aakindustry.com/info-detai , l/pressure-control-valves-aak461

AAK Multifunctional Hydraulic Cartridge Valve, benefit all 3 Parties

Monroe is from Sweden and has been purchasing hydraulic threaded cartridge valves from Ningbo for 3 years. In January of this year, their customer wanted to place a repeat order for one of their hydraulic unit equipment, but requested a 20% price reduction. Monroe wanted to reduce the price of the check valve, relief valve, and solenoid unloading valve in the hydraulic unit by 30% to meet customer requirement, but the original hydraulic threaded cartridge valve manufacturer cannot accept the new price. Monroe contacted AAK for inquiry. When I saw his target price, I directly informed him that this price could not be achieved. Monroe did not give up and emailed me again. After communication, it was learned that his customer requested a 20% price reduction for the equipment. I felt a bit strange, but immediately realized that last November, AAK customized an integrated multi- function hydraulic threaded cartridge valve for a Spanish customer, replacing the 3 standard hydraulic threaded cartridge valves in their hydraulic systems. I suggested him sending me the schematic diagram of their equipment hydraulic system for a look. At first, he wasn't willing to do so, but when I sent him the customized case for this Spanish customer, he immediately compromised. After discussion, AAK engineers found that Monroe's problem was similar to that Spanish customer. As long as the functions of the check valve, relief valve, and solenoid unloading valve in the equipment are integrated into a hydraulic threaded cartridge valve, not only can cost be reduced, but also the hydraulic oil circuit is more simplified. After 45 days, AAK sent 10 samples of hydraulic threaded cartridge valves. Last week, Monroe emailed me that AAK hydraulic threaded cartridge valve was installed on their hydraulic unit, and the equipment functionality was not affected. He gave the customer a 30% discount, and the customer was surprised by the extra 10% discount and pleased to place the repeat order. Monroe told me that AAK multifunctional hydraulic threaded cartridge valve allows him to earn an additional 15% more in profits, his customer gets additional discounts, and AAK also has a new customer. I am happy to do things that benefit all 3 parties. 1. The hydraulic threaded cartridge valve sleeve is provided with a communication valve hole, a working port of the oil cylinder, a hydraulic control port of the oil tank, an oil inlet port, and an oil return port. A check valve spool is provided in the valve hole to control the on-off of the oil inlet and the working port for oil feeding or unloading. In this way, the one-way control function is realized, replacing the check valve of the original structure. 2. The hydraulic threaded cartridge valve is provided with an overflow valve spool, which connects the valve hole and the oil return port to provide a damping hole for unloading. At one end of the damping hole, there is an unloading valve spool that controls the opening and closing of the damping hole and the oil return port. The check valve spool is provided with a connecting channel that connects the valve hole and the working port for overflow or unloading. This achieves the unloading function, replacing the original structure of the solenoid unloading valve. 3. When the check valve spool is separated from the working port, the oil inlet port and the working port are connected to the unloading hydraulic control valve spool, and the connection between the valve hole and the overflow valve spool of the oil return port can also be disconnected. This achieves the overflow function and replaces the original structure of the relief valve. AAK hydraulic threaded cartridge valve, 3 in 1 function, saving over 40% cost for customer, you can also try it! https://www.aakindustry.com/info-detail , /cartridge-valves-aak537

AAK Hydraulic Pressure Control Valve, 5% higher finish machining accuracy

George comes from a hydraulic valve company in Germany. He likes to choose old suppliers to place orders. Some time ago, he placed an order of hydraulic pressure control valve with machining allowance of 0.3mm with an old supplier. After 3 proofing, his customer still did not approve the samples of the hydraulic pressure control valve. George was very angry. Before ordering this hydraulic pressure control valve, he confirmed the parameters with the manufacturer several times, especially the machining allowance of 0.3mm. The manufacturer guaranteed no problem. Unexpectedly, the accuracy error of the hydraulic pressure control valve sample was 10% higher, and even after revising samples for 3 times, it still can not meet the machining allowance of 0.3mm. George has to face the technical shortcomings of the old manufacturer, the sample pushing of the customer, and the situation of no suitable hydraulic pressure control valve manufacturer to make samples. He contacted the all the hydraulic valve manufacturers cooperated in the past, but none of them was able to make a hydraulic pressure control valve with a machining allowance of 0.3mm. He kept looking for a new hydraulic pressure control valve manufacturer online and came across AAK hydraulic valve on B2B. George left a message on our website www.aakindustry.com: I saw AAK article introducing the hydraulic valve with machining allowance of 0.3mm. We have a hydraulic pressure control valve requiring machining allowance of 0.3mm. Can you sample it? For those customers who directly require to make samples like this, basically, they encountered the sample failure from other hydraulic pressure control valve manufacturers. After communication, we know that his old supplier has failed to deal with the 0.3mm finishing hydraulic pressure control valve samples for 3 times. After checking George's hydraulic pressure control valve drawings and various parameter descriptions, AAK engineers confidently informed that the sample could be successful at one time. George may think that only AAK can help him solve the problem. He directly paid a proofing fee of $1,200.00 and asked us to send the hydraulic pressure control valve samples within 3 weeks. We appreciated George's frankness and asked the workshop to cooperate fully. After 15 days, we successfully sent the samples of hydraulic pressure control valves. On the third day after George received the samples, he told us that the machining accuracy of AAK hydraulic pressure control valve not only met the requirement of machining allowance of 0.3mm, but also increased by 5%, which made him admire very much. In order to ensure the accuracy of finish machining size allowance, the heat treatment process is the most critical step. At present, most hydraulic pressure control valve manufacturers adopt local quenching, the workpiece heat treatment process is not easy to control, and most of them are easy to deform. As early as 6 years ago, AAK adjusted local quenching to overall quenching. At the same time, vertical flow treatment must be required for the hoisting mode in the process of quenching and tempering, so as to minimize the influence of the tissue stress and thermal stress of the workpiece heat treatment on the deformation, so as to meet the dimensional allowance requirements of finish machining. The next day, George decided to cancel the order of the hydraulic pressure control valves with the old manufacturer and told me that AAK hydraulic valve is his old supplier now. Maybe he meant to tell me that his hydraulic pressure control valves will be purchased from AAK in the future. AAK hydraulic pressure control valves, the finish machining accuracy is 5% higher than the requirements of German customer. You can also have a small try! https://www.aakindustry.com/info-detai , l/hydraulic-pressure-control-valves- aak178

Fully Automatic Machining of AAK Hydraulic Cartridge Valve Cage

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!

AAK Hydraulic Cartridge Counterbalance Valve Benchmarking SUN

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

AAK Hydraulic Cartridge Valve Manufacturer View about Temporary Appointment

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.

AAK Hydraulic Flow Control Valves Cared with Every details

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

The valve spool is stuck, AAK hydraulic directional control valve solved it

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

The accuracy of AAK hydraulic relief valve is up to 0.3μm, Fred admired

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

AAK Hydraulic Cartridge Valve Spool High Accuracy and Stability

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!

AAK Hydraulic Cartridge Relief Valve No Blockage

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
