Alston is the purchaser of a British hydraulic valve company. He has been purchasing hydraulic valves in Ningbo for 3 years and has been very smooth. Last month, he purchased a batch of hydraulic pressure valves. During the sample approval process, the automatic pressure regulation of the hydraulic pressure valves was not very stable. The hydraulic valve manufacturer checked again and again, but still could not find the reason. Alston had a headache. Alston realized that he has to look for a new hydraulic valve manufacturer to try, otherwise the order would go away. When he sent the detected data and parameter requirements to the hydraulic valve manufacturers he had previously contacted, only one manufacturer told him that it was the problem with the pressure spring material or the processing process, but because of power limitation, he has no time to produce this hydraulic pressure valve order. The other manufacturers replied that they need to make samples first before they knew the results. Alston felt the pressure. Coincidentally, he heard that the AAK HYDRAULIC VALVE paid great attention to the pressure spring. When we received his email, we understood that this hydraulic pressure valve has very high requirements for automatic adjustment of the pressure spring. We produced and supplied a batch of similar designs to a Russian customer as early as 2 years ago, so we sent him pictures of similar hydraulic pressure valves. Alston felt that AAK HYDRAULIC VALVE could solve this dilemma and asked how long it would take to produce 1000 hydraulic pressure valves. We advised that the delivery time depends on the production time for the pressure spring, because of power limitation, the production capacity of the pressure spring is very low. According to the warehouse inventory, there are 440 inventories. For the remaining 600, according to the current power consumption, we conservatively estimate that it will take an additional 45-55 days. Therefore, only 400 hydraulic pressure valves can be shipped to him, and the remaining 40 pressure springs should be reserved for make samples for other customers. For this pressure spring, most of our peers use carbon steel, which will cause the plasticity and toughness of this valve spool to be very general, the tensile strength is relatively weak, and the stability is difficult to control. There is no problem to use it for the general quality requirements. As early as 5 or 6 years ago, AAK has replaced the carbon steel pressure spring with the piano steel wire pressure spring imported from South Korea. There were only a few manufacturers using it in the whole hydraulic industry in Ningbo. The piano steel wire pressure spring imported from Korea has high strength, good elasticity, fatigue resistance, creep resistance and toughness, smooth and clean surface, strong anti rust ability, specified tensile strength and torsional performance, and there will be no cracks, folds, scars, tensile cracks and corrosion on the surface. AAK hydraulic pressure valves, with imported piano steel wire pressure spring, can be used with peace of mind. You are courage to try a small order. https://www.aakindustry.com/info-detail/hy , draulic-pressure-valves-aak91

Mason, an old customer of hydraulic valves from the United States. In March this year, he was not satisfied with the quotation of one of our hydraulic valve blocks, which was nearly 7% higher than his target price, so he didn't place an order with AAK HYDRAULIC VALVE. Unexpectedly, he sent an email last week asking whether our quotation of hydraulic valve block in March was still valid. We replied that you were our old customer and the price must be valid. Mason also frankly told us that there was a problem with the hydraulic valve blocks he purchased, which made him very headache now. After communication, we learned that there were no problems in the preliminary test and shipment inspection on the hydraulic valve blocks produced by his previous hydraulic valve manufacturer. In the recent month, users had gradually reported that after setting up and debugging, the surface of the hydraulic valve block fell off paint, rusted, and even there was pollution inside the hydraulic system. Nearly 60% of the 300 hydraulic valve blocks purchased had this situation, and only 40% were still on sale. His boss found something wrong and suspended the sale of the remaining products. The hydraulic valve manufacturer believed that this was caused by the improper use of the hydraulic valve block by the user, and was only willing to replenish 10% of goods to solve this problem. His boss asked him to find a qualified hydraulic valve block supplier as soon as possible. Because the use scenario of this hydraulic valve block was special, Mason knew that AAK HYDRAULIC VALVE could solve this problem, but his did not have authority to pay a 7% higher price. He contacted no less than 10 hydraulic valve manufacturers, and only 3 of them replied. They could solve the paint falling and rust spots on the surface of the hydraulic valve block, but the internal pollution could not be 100% avoided because they did not know the user's operation. The remaining hydraulic valve manufacturers did not give any reply at all. Mason was very helpless. He had to bite the bullet and asked his boss for help if the purchasing price could be raised. When his boss learned about the whole purchase process, he asked Mason, why he did not report this situation in March? After the delivery date provided by AAK HYDRAULIC VALVE was agreed by his users, Mason sent us the order for this hydraulic valve block, and asked us to ship as early as possible. At the same time, his boss was curious about how we did it. The anti-rust treatment of AAK hydraulic valve block in the past is the same as that in other factories, which adopts surface painting or conventional electroplating treatment. The pain point of this process is that the hydraulic valve block is easy to be scratched, causing corrosion and increasing system pollution. We understand these potential problems of this process, and our technical team adheres to the new process exploration, so that AAK now has its own unique anti-rust technology. With the increasing requirements for product aesthetics and pollution control, AAK HYDRAULIC VALVE has its own proprietary anti-rust treatment technology, it electroplates a 0.02 ~ 0.03 mm thick special coating on the surface of the hydraulic valve block. This coating has excellent adsorption, not easy to fall off and also bright appearance. Only on this point, AAK has crushed most peers. For the production of hydraulic valve block, AAK has proprietary anti-rust technology, which is enough to reassure you. You can have a small try.

Barnaby is from Brazil, has purchased hydraulic threaded cartridge valves in Ningbo for 5 years. He has purchased several standard parts of SUN cartridge valves from AAK. He always thinks that AAK cartridge valves are expensive. At the beginning of last year, the customer complained that their hydraulic cartridge valve, installed in the hydraulic power unit, had leaked in 6 months. The original hydraulic cartridge valve manufacturer said that the seal ring structure was damaged in the assembly process, and the seal ring could only be replaced, but after 1 month, there was leakage again. Barnaby realized that the hydraulic threaded cartridge valve from this manufacturer has a service life of only 6 months. The boss is not satisfied with his purchase. There are always complaints from customers. Barnaby feels the pressure from the boss. Barnaby emailed me in August last year: Can AAK ensure that each hydraulic threaded cartridge valve has no leakage within 1 year? After communication, we learned that he was facing difficulties in purchasing from Ningbo cartridge valve manufacturers. According to the cartridge valve manufacturers he mentioned, I admit that the price of AAK hydraulic threaded cartridge valve is about 20% higher than those of these peers. However, I guarantee that the service life of AAK hydraulic threaded cartridge valve is twice that of its peers. Barnaby's hydraulic threaded cartridge valve has a service life of 6-8 months if it is sealed in a conventional or universal way. AAK rarely uses traditional methods but to optimize the sealing method of the original hydraulic threaded cartridge valve, which has a service life of at least 12 months. After 45 days, AAK sent 38 hydraulic thread cartridge valve samples and promised to refund the full amount of the fee if there was leakage within 12 months. The day before yesterday, Barnaby emailed me that the customer had been using AAK hydraulic threaded cartridge valve for nearly 6 months, and there was no complaint. I told him that there would be no complaint in another 6 months, and did not say anything else. Unexpectedly, he listed 12 standard parts of SUN hydraulic thread cartridge valves yesterday for us to quote. This is an action that Barnaby has never done before. By the way, for this type of hydraulic threaded cartridge valve, AAK sealed it as below. Most of the cartridge valve manufacturers in Ningbo do not use this sealing method or structure. 1. Selection of sealing material: The material of O-ring is made of PU polyurethane rubber sealing ring made in Japan, and the material of retaining ring is polytetrafluoroethylene. Although the cost of these materials is more than twice that of general materials, AAK insists on selecting the most durable material to ensure the service life of hydraulic threaded cartridge valves. 2. Innovation inside the valve body: the regulating and driving device of the hydraulic thread cartridge valve is installed in the valve sleeve, and the valve spool is of inverted cone structure. 3. Optimization of sealing mode and structure: the sealing ring group is composed of O-ring and retaining ring. The sealing ring group is between the valve sleeve and the valve spool, and the retaining ring is of double-sided structure. The retaining ring not only seals, but also protects the O-ring from being squeezed. With the protection, the O-ring is not easy to be deformed and damaged, and the O-ring can avoid to be cut during installation. AAK hydraulic threaded cartridge valve, although 20% more expensive, its service life is twice as long as that of other hydraulic cartridge valve manufacturers in Ningbo China.

9 months ago, we received an email from an old customer in the UK, informing that Berge had transferred from the quality control department to the import department. We could see from the email of the young man's self-introduction that he was full of confidence in procurement. Unfortunately, the first hydraulic valve order went wrong. A batch of orders for hydraulic flow valves shipped from a hydraulic valve manufacturer in Ningbo had no problem when tested before leaving the factory. However, when the goods were delivered to customers, the company received a series of quality complaints from consumers in only 1 month, and nearly 20% of the hydraulic flow valves had leakage. The boss was not very happy, and requested Berge to solve the guest's complaints within 1 week. Berge had discussed with the original hydraulic valve manufacturer several times, but it has not been effectively solved, and he even wanted to resign. Shawn, a former old purchaser, felt his frustration and reminded him to communicate with AAK HYDRAULIC VALVE to see if it could be solved. We received Berge's email with product drawings, pictures and test data of the defective hydraulic flow valves. We preliminarily judged that there was a problem with the valve spool. In order to solve the problem at one time, Berge asked his hydraulic valve manufacturer to send 5 samples of defective hydraulic flow valves to AAK HYDRAULIC VALVE for thorough inspection. After receiving the hydraulic flow valve samples, frankly speaking, the main line type of the hydraulic flow valve was acceptable. The problem was that the valve spool deviated from the central axis, resulting in leakage. Of the 5 hydraulic flow valve samples sent, two were in this situation, and the other three were of acceptable quality. This proved what we said before that it was difficult to 100% ensure that the valve spool did not deviate from the central axis due to human error, which was a hidden problem among peers. I suggested him to replenish 40% hydraulic flow valves to their customer within 30 days. If the customer could accept this suggestion, we would give priority to the production of these replenished hydraulic flow valves. A week later, Berge informed by email that his boss had agreed to the plan and his customer could accept only 20% replenishment. They just repeatedly stressed that the replenishment of the hydraulic flow valve could not have any quality problems. AAK realized a few years ago that the hydraulic flow valve produced by CNC lathe has high requirements for operators and is prone to human errors, resulting in the deviation of valve spool from the central axis. On the production equipment, AAK HYDRAULIC VALVE have imported the Swiss machine tool with the highest precision to make up for the short board of CNC lathe. At present, less than 10% of the peers have this equipment. It can replace 7 groups of accessories at random. The high-pressure hydraulic flow valve produced by Swiss equipment has high precision, which is at least 20% higher than that of domestic conventional CNC lathe. Not only the precision is high, but also the stability is guaranteed. Last week, we received Berge's good news email. The customer was very satisfied with the replenishment of the hydraulic flow valve, and the boss was also very happy. Berge also joked with us that it was thanks to us AAK HYDRAULIC VALVE, otherwise he would have changed his job. AAK hydraulic flow valve, our old customers have been purchasing because of trust.
