| Message: | 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 hydraulic pressure reducing valve used is critical to the stability of the equipment. Their engineer designed the hydraulic pressure reducing valve according to the system principle, and Liam found a 5 years experienced hydraulic pressure reducing valve supplier to test the sample. After 50 days, the equipment commissioning was not smooth, and after 1 hour of operation, the support was unstable and noisy. At first, it was thought that it was caused by the leakage of the hydraulic pressure reducing valves, but there was no abnormality after testing the hydraulic pressure reducing valves individually. Their engineer spent another 2 days checking each hydraulic element one by one, but could not find the root cause of the problem.
The delivery time of the prototype was less than 2 months. The boss was worried and asked Liam to contact the manufacturer of the hydraulic pressure reducing valves to help analyze the cause. 1 week passed, Liam consulted more than 20 hydraulic cartridge valve manufacturers, but none of them gave a plan. Liam was helpless and had to continue to find new manufacturers of hydraulic pressure reducing valves.
