Kate, the buyer of Terex company, was asked by the head office last month to purchase a batch of hydraulic pressure valves within 3 months. She vowed to the boss that it would be completed in 2 months. As usual, Kate sent the hydraulic pressure valve inquiry to more than 10 hydraulic valve manufacturers she was familiar with, including American hydraulic valve manufacturers and Chinese hydraulic valve manufacturers. She chose 3 factories to provide hydraulic pressure valve samples for testing. After the test, the technical department informed that only the hydraulic pressure valve samples provided by American manufacturer were qualified. The trouble is that the price of the qualified hydraulic pressure valve exceeds 40% of the company's budget price. She has no authority to decide to use the products of this American hydraulic valve manufacturer.
After discussion with the technical department, she learned that those unqualified hydraulic pressure valves are mainly due to the wear or fracture of the sealing ring after 15,000 times of impact during the durability test of the hydraulic pressure valve, resulting in the leakage of the hydraulic pressure valve. Only those hydraulic pressure valves that have not leaked for more than 40,000 times are qualified. She was very depressed that the quotation of the other 3 hydraulic pressure valves was within the budget, but the quality was unqualified. At this time, Kate realized why the company gave him 3 months to purchase. She hurriedly sent inquiry to new hydraulic valve manufacturers, and specially emphasized the need for hydraulic pressure valves with more than 40,000 durability tests. The trouble is that no hydraulic valve manufacturer gave her an offer. Kate realized the difficulty of procurement. She had wasted 3 weeks. Procurement was still in its infancy, and the technicians had been urging progress.
After learning about Kate's purchase status, the colleague recommended her to contact AAK HYDRAULIC VALVE to try. When we received the hydraulic pressure valve drawing from Kate, we first gave a quotation. She told us very frankly that the price of AAK was 20% higher than that of other China hydraulic valve manufacturers, but 15% cheaper than that of the United States. She needed us to reduce the price greatly. We suggested providing the hydraulic pressure valve samples for testing first, and then discuss the price after passing the test.
2 weeks later, Kate informed that the test was qualified and AAK hydraulic pressure valve durability test had reached more than 40,000 times. She was surprised why AAK passed the hydraulic pressure valve durability test, while the other hydraulic valve manufacturers in China failed. AAK hydraulic valve was also eliminated by customers 2 years ago because the durability test of hydraulic pressure valve failed to meet the standard. AAK has increased research and development on the sealing ring. After more than thousands of tests in half a year, AAK chose to use a special PU polyurethane rubber sealing ring from Japan to overcome this technical problem. Its wear resistance and high pressure resistance are far better than other rubber sealing rings. The vast majority of domestic hydraulic valve manufacturers use rubber sealing rings, and the maximum limit of their durability test is 20,000 times.
Maverick is from a Canadian hydraulic equipment manufacturing company. In the first half of last year, the high-temperature hydraulic power unit dedicated to meltblown equipment sold by their company for less than 4 months was complained by customers.
At the beginning of this year, Liam from the Netherlands found AAK Hydraulic Valves on Google. He told me that he encountered the dilemma of purchasing hydraulic pressure reducing valves. Their company has developed a hydraulic support column used in coal mining.
The processing difficulty of hydraulic relief valves with deep hole is a pain point in the industry. The greater the length diameter ratio, the greater the difficulty. Pablo, an American Hydraulic customer, has recently been besieged by an order for hydraulic relief valves with a length diameter ratio of 11:1.
2 months ago, Jackson from the United States left a message on AAK website: I read the article "The throttling groove is changed from double to single triangle. The hydraulic counterbalance valve has no vibration. AAK makes Henry feel at ease for vacation".
