Last Friday, I received an email from Shikha, an Indian hydraulic directional valve customer. I was depressed all weekend and didn't even want to reply to the email. In July last year, Shikha placed a trial order for a hydraulic directional valve. Three months later, Shikha asked the price of the hydraulic directional valve to be reduced by 40%, on the grounds that the order quantity of the hydraulic directional valve is bigger now. At that time, we only reduced the price by 5%, but Shikha forwarded the email of other manufacturer accepting the price reduction to me. It means that if AAK hydraulic valve can not accept the price reduction, the order will be placed with other hydraulic directional valve manufacturer. It turned out that he tried the order at AAK and another manufacturer at the same time last July.
Last week, Shikha contacted AAK again and asked us to accept the same price as last time. I felt that the hydraulic directional valves he purchased from other manufacturer was not smooth, then he turned back to AAK, so we insisted on the original quotation and got his weird email on Friday: "Why does AAK have to make money to make this hydraulic directional valve? Don't many manufacturers in China make a few points of profit?"
Indeed, there are hydraulic directional valve manufacturers doing market common products. The only thing they can do is to compete with low price, and then make small moves under table in production. This is the involution of the hydraulic valve industry. AAK does not want to accept such orders for hydraulic directional valves, nor does it want to contact such customers.
No matter what enterprise, if it doesn't make money, it can't find its mission, vision and values. If an enterprise deliberately creates its mission, vision and values, it is illogical. If the enterprise doesn't make some money first, where will these things come out of the mind? No matter how small an enterprise is, it may not realize the value of the enterprise until it has a net profit of at least one million yuan. For example, in what aspects has AAK hydraulic valves created value for customers and brought additional benefits to customers, as well as benefits that can not be given by hydraulic valve peers, not to mention the R & D cost of hydraulic valves, production process upgrading cost and equipment renewal cost. On the way of making money continuously, the enterprise's mission, vision and values will be clearer until the enterprise's mission, vision and values are slowly found and what the enterprise really wants to say and do.
In the past few years, the conversion rate of AAK online inquiry is 17%. Does this 17% seem not high enough? But AAK never does business for poor enterprises. Our customers are concentrated in European and American brand hydraulics, and their operation is standardized. As long as the quality of your hydraulic valves is stable, it is really easy to discuss the hydraulic valve project, rather than forcing th

Recently, I received the second re-order of a hydraulic pressure reducing valve from French client Chinning. I still remember when I first met Chinning in 2020, Chinning purchased hydraulic pressure reducing valves in a hydraulic valve factory and encountered quality complaints from her customers. The hydraulic pressure reducing valve was deformed in less than 3 months, and some valve spools and valve sleeves were seriously worn. More and more customers began to return goods, and the old suppliers did not cooperate with her work. Chinning had a big headache at that time, and the owner kept putting pressure on her to find a hydraulic valve manufacturer with exquisite quality as soon as possible. Chinning did not find a new hydraulic valve manufacturer very smoothly. Because her hydraulic pressure reducing valve had a special use scenario and required high hardness of materials, it was unbearable for ordinary factories. At the same time, under the environmental protection policy of 2019, many previous heat treatment and processing factories were shut down, so the supply supporting system was disrupted, and the heat treatment and processing of many hydraulic valve manufacturers could not keep up. how does AAK ensure the service life of hydraulic valve products We didn't answer directly, but asked her if the hydraulic valves you purchased had the problem of deformation and rapid wear. She also replied quite frankly that she should find a hydraulic valve manufacturer that paid attention to the service life of hydraulic valves in the fastest time. I sent her several samples of hydraulic pressure reducing valve and told her that different parts of our hydraulic pressure reducing valve have different material hardness standards, and some could reach about 50-55HRC or higher. There is even no problem with 65HCR with special requirements. The service life of hydraulic pressure reducing valve is our hard index. More than one week after we sent out the samples of hydraulic pressure reducing valve, we received Chinning's email, including the drawings of hydraulic pressure reducing valve and the hardness requirements for various components. She asked whether we could produce this hydraulic pressure reducing valve? I told her that his hydraulic pressure reducing valve is not difficult, but just the working scene is some special. As long as the heat treatment process is a little unique, it could ensure her requirements. The long service life of hydraulic valve is the most critical.
hydraulic relief valves . purchased a batch of hydraulic relief valves for crane system in because the original supplier was not able to meet the delivery. He sent an email last week saying with hydraulic relief valves, the stability is 8% higher than that of the original supplier, and there is almost no external leakage. This surprised him. The use experience of hydraulic relief valves has benchmarked with their previous local hydraulic relief valve manufacturers The vast majority of hydraulic valve bodies are made of nodular iron, vermicular iron and gray iron and cast with resin sand as the molding medium. Therefore, there is sticky sand in the casting, which is easy to pollute the oil system and block the valve and filter, which is the key factor affecting the stability of hydraulic relief valves. Most of the common sand cleaning methods of hydraulic relief valves used in the industry are shot blasting and electrochemical sand cleaning, all of which have limitations. 1. Shot blasting can not completely remove the sticking sand from the valve hole with complex structure and small oil passage, which is easy to affect the tightness and product accuracy, and is not conducive to the stability of the hydraulic relief valves. 2. Electrochemical sand cleaning can relatively remove the sticky sand in the narrow oil passage, but it has high energy consumption, high operation intensity of workers, easy to have human errors, can not completely remove the sticky sand, and is not conducive to the stability of the hydraulic relief valves. Improving the quality of hydraulic parts processing process, improving the cleanliness level and ensuring the stability of hydraulic relief valves has always been the hard index of hydraulic relief valves. Auxiliary processing of hydraulic parts mainly includes: sand cleaning of valve body, deburring or residue treatment of parts and cleaning of hydraulic parts. How does do the sand cleaning of hydraulic relief valves technical team has continuously improved the sand cleaning process of hydraulic relief valves after years of technical improvement. For the sand cleaning of small complex castings, has its own unique sand cleaning 5 methods, namely: artificial aging - Pickling - rinsing - rust prevention - ultrasonic cleaning. Artificial aging is used to reduce the binding force between the casting and sand, acid pickling is used to remove the oxide skin at the joint between the sand and the casting to peel the sand from the casting, and then the explosion of compressed air during ultrasonic cleaning is used to peel off the sand, so as to achieve the purpose of sand cleaning. has its own unique advantages of sand cleaning 5 methods: (1) it is less affected by the casting structure; (2) it is
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 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 When we mentioned 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 will be deducted from the payment for in the future. 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. 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 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
When I opened the mailbox this morning, I saw an from , which should be a re-order for the hydraulic relief valve, because he asked about the durability of hydraulic relief valve spool last week. Opening the , it is indeed the need for purchasing a large number of 420 hydraulic relief valves, and requiring 3 years of quality guarantee. is a purchaser of . 3 years ago, a customer of his company complained that the crane was easy to depressurize during work, resulting in the inability of the crane to bear the force. Especially after the working temperature reaches 55 C, the pressure cannot go up. Field engineers believe that this is a problem of the hydraulic system, such as low pressure regulation of the hydraulic relief valve, wear of the hydraulic system, or oil pollution. No abnormality was found after inspection. Finally, it was determined that the fault occurred on the hydraulic relief valve. After disassembling the hydraulic relief valve, it was found that the cone valve spool was worn, affecting the sealing of the hydraulic system, so the oil pressure could not rise. The customer does not understand why the valve spool of this hydraulic relief valve is worn after less than 2 years of use. The customer requested to replace with a batch of hydraulic relief valves with durability of more than 3 years and use them on these 12 faulty cranes. At that time, contacted more than 10 hydraulic relief valve manufacturers and got reply that the warranty could not be achieved for 3 years. Some hydraulic valve manufacturers replied that they only have 50% confidence. This result embarrassed Bruce. The customer requirements for the hydraulic relief valve could not be implemented, how he should explain to the owner. I received message from on the of can really provide a 3-year warranty hydraulic relief valve I replied directly: just give it a try then you will know. I can't make money with the trial orders of several samples, and you can't lose money. Maybe was stimulated and sent us the test order the next day for 4 hydraulic relief valves. also frankly told that two other hydraulic valve manufacturers would also try the order at the same time. Their plan is that each factory will be tested for 4 samples, with a total of 12 hydraulic relief valves to meet the urgent needs of customer first. About 2 years after the samples were sent, we received from again for another trial order of 8 hydraulic relief valves. I felt strange and thought that they actually didn't have big quantity order for hydraulic valves. Until last week, from his email, we learnt that they had tested the hydraulic relief valves provided by for 3 years. Indeed, 3 years later, hydraulic relief valves still worked normally, and the hydraulic relief valves provided by the other two manufacturers had faults in less than 2 years.
He has done very well and occasionally inquires about the price with HYDRAULIC VALVE. For the hydraulic check valves purchased some time ago, the production director found that 20% of the hydraulic check valves have parameters that do not meet the standard, so they must get new qualified ones to the workshop within 20 days, otherwise the delivery of customer order would be delayed. Charles asked the original manufacturer of the hydraulic check valve to complete the replacement within 2 weeks. The manufacturer is willing to replenish, but the production can be started only after 15 days, that is to say, it will take 30 days to replenish. tried to find other suppliers of hydraulic check valves, and all replied that it could not be completed in such a short time. realized that something was going to happen and began to look for a new hydraulic valve manufacturer, contacting factories one by one. thought that had also participated in the quotation of this hydraulic check valve, and the samples provided also met the requirements, but it was not considered because the quotation of was slightly higher than that of other hydraulic valve manufacturers by 7%. sent us an e-mail to ask whether the quotation of hydraulic check valve offered 6 months ago can be maintained, and if we can finish an urgent order of 100 hydraulic check valves in 10-12 days. I felt that this should be an order for hydraulic check valve encountered with problem. told us the truth. About 20% of the hydraulic check valves produced by the original factory were unqualified and rejected by their production director. Now he must replenish them as soon as possible. General hydraulic valve manufacturers are unwilling to make such aftercare orders, but HYDRAULIC VALVE don't think so, because , as a production factory, has the same goal as the importer, that is to serve users well, so is more willing to help customers and solve complaints from users together. Fortunately, the corresponding materials are in stock. Combined with the 24-hour production line, our production director conservatively estimates that it can be completed in 12 days. asked us to start blanking now and the hydraulic check valve order will be issued tomorrow. After 10 days, 100 hydraulic check valves were successfully finished. was very happy and quickly air freighted these hydraulic check valves to the Thanks to the God, 100 hydraulic check valves finally arrived at their workshop in 20 days. informed us by email that their engineers installed, debugged and tested hydraulic check valves, which were all normal. The 7% higher price was also agreed by his owner. The owner was very amazed that can deliver so quickly and the quality was better than that of the original manufacturer.
At the beginning of this year, received an order from African customer for excavators with a delivery time of 2 months, which means that all accessories must be in place within 1 month, including 600 hydraulic cartridge valves. The production time for the factory is a little more than 2 weeks. The purchaser Peter sent the order information of the hydraulic cartridge valve to all the hydraulic valve manufacturers he contacted before at the first time. More than 20 hydraulic valve manufacturers said that they could not complete the order of the hydraulic cartridge valve in such a short time, and it would take at least 3 - 4 weeks. His supervisor was not satisfied with this delivery time and asked him to find a new hydraulic valve manufacturer. After the email was sent, there was basically no sound. Peter was very helpless and worried. Peter asked Mark for help. HYDRAULIC VALVE to ask if could produce 600 hydraulic cartridge valves in 2 weeks and CC Peter, and joking at the end of the email that if HYDRAULIC VALVE could not complete the hydraulic cartridge valve order, then there is no need to waste time on looking for a new hydraulic valve manufacturer. According to the drawings they sent, technical department found that this was very close to the hydraulic cartridge valve supplied to a Russian customer last year, so the time in the early stage of the production of the hydraulic cartridge valve was saved. After the price of the hydraulic cartridge valve was approved, the process data could be configured on the computer on the same day and the production could be carried out the next day. 2 weeks later, 600 hydraulic cartridge valves were delivered on time, which was the first of all the accessories purchased by Peter to arrive at the company's warehouse. Peter didn't expect that the hydraulic cartridge valve he was most worried about was the first to be completed. Peter appreciated the advice from Mark and was also surprised that could complete this in 2 weeks, while his previous hydraulic valve suppliers needed 3-4 weeks. Mark told : 1. is his most trusted hydraulic valve manufacturer. can surprise him every time when the hydraulic valve order is urgent. 2. has a large amount of data storage and clear classification. For hydraulic valves with relevant data, they can use the most advanced UG / SOLIDWORK software and finite element analysis method to configure process data in 2 hours, which is 3-6 times faster than that of other suppliers. 3. is equipped with advanced machine tools imported from Swiss, coupled with their own modified fixtures, the production speed is accelerated and man-made errors are avoided at the same time. After listening to the introduction realized that only a good hydraulic valve supplier can make his purchasing smooth. successfully completed this urgent order.
