A safety valve is becoming increasingly popular among different industrial communities. The reason for such increased demand due to its ability to control and check the pressure of fluids along with diverting the routes for transporting them in designated outlets. These valves are made of various durable metals and can withstand high temperature till a specific limit. Safety relief valve helps in regulating fluid movements. For checking pressure, there is no better alternative than pressure relief valve. When it comes to checking boiler temperature then thermal relief valve is the best.

Henry is a purchaser of a hydraulic power unit manufacturer in the United States. He almost lost his job when he purchased the hydraulic pressure relief valves in the first time after just joining the company. AAK high-precision hydraulic pressure relief valves saved the job for him. Last October, one of their African customers customized a batch of hydraulic power unit equipment for use in African mining bases. The requirements of the equipment for the hydraulic pressure relief valves used are that there is no abnormality within 1 year. Henry contacted more than 10 hydraulic pressure relief valve manufacturers and screened 4 samples from each of 4 factories. A month later, the engineering department debugged these hydraulic pressure relief valves. Almost all hydraulic pressure relief valves from every factory have unstable hydraulic system pressure, but only the proportion is different. At first, the engineer thought it was due to the installation of hydraulic pressure relief valves or the problem of oil quality. After several commissioning, it was found that the outlet pressure of hydraulic pressure relief valves was almost equal to the inlet pressure. After disassembling the hydraulic pressure relief valves, it is found that the geometric tolerance is out of tolerance due to the accuracy of the main valve spool and valve hole. After knowing this, the boss thought that Henry had a problem on the communication with the hydraulic pressure relief valve manufacturers and asked him to solve the purchasing of the hydraulic pressure relief valves with the manufacturers within 4 weeks. Henry has made two rounds of screening for hydraulic pressure relief valve manufacturers and emphasized the working conditions, but still no one can achieve that every hydraulic pressure relief valve has no problem. He felt that he was cheated. The water in the hydraulic pressure relief valve industry was too deep. Henry found AAK hydraulic valve on Google and left a message on our website: Can AAK get the geometric tolerance of each hydraulic pressure relief valve consistent? After several rounds of e-mail communications, we learned about what happened when he purchased hydraulic pressure relief valves for the first time. We can only comfort him that he was misled by hydraulic pressure relief valve manufacturers due to lack of experience. He can test the samples of AAK hydraulic pressure relief valves. Three weeks later, AAK sent Henry 5 samples of hydraulic pressure relief valves. Their engineer tested each sample 3 times, and the hydraulic power unit equipment was normal. The boss praised his emergency ability. Now Henry doesn't have to worry about losing his job. We told Henry that according to the working conditions and drawings of this hydraulic pressure relief valve, the accuracy of each hydraulic pressure relief valve is required to meet the standard and be stable,

hydraulic equipment, which needed to use hydraulic relief valves. The boss asked that the procurement cost of the hydraulic relief valves should be reduced by 15% on the premise of ensuring the quality. He contacted the original hydraulic relief valve manufacturer, and the manufacturer replied that it was impossible. In desperation, he had to find a new manufacturer of hydraulic relief valves. Rodriguez has participated in the Shanghai PTC exhibition and collected some hydraulic relief valve manufacturers, which have great advantages in terms of price. The quotation of some hydraulic relief valve manufacturers is only half of that of manufacturers, and the quotation of some hydraulic relief valve manufacturers is 60% cheaper than that of manufacturers. He is a little surprised that there is such a big difference in the quotation of different manufacturers for the same hydraulic relief valve. They began to test the parameters of the hydraulic relief valves from 3 manufacturers, but did not require to send samples, because the price of was 20% - 30% higher than that of other manufacturers. A month later, the hydraulic relief valve samples from the 3 factories were tested and they all failed to meet the indicators of American manufacturers. The pressure of some hydraulic relief valves could not rise within a few days after the equipment was installed. Rodriguez initially screened the manufacturers of hydraulic relief valves and used the 3 factories with low prices. Maybe it proves that Cheapest is the dearest. He changed his strategy and used the hydraulic relief valve manufacturers with relatively high quotation to test the samples. offers the highest price, but it is still about 30% cheaper than manufacturer. At the same time, promised that the quality could fully match that of manufacturer. According to the hydraulic relief valve drawings and working condition information provided by Rodriguez, sent the samples of the hydraulic relief valves after 25 days. A month later, Rodriguez sent an email that hydraulic relief valves passed the test, and the parameters were benchmarked with those of the original manufacturer, and even some details and appearance were visually more exquisite than those of the manufacturer. He would like to know how makes hydraulic relief valves that surpass American manufacturers has a high-precision CNC machining center imported from and various independent fixtures upgraded and refitted by itself, which eliminates human errors and avoids faults such as stuck valve spool of hydraulic relief valves.
