AAK Hydraulic Pressure Reducing Valves Unique Design Skills

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. According to Liam, this is a systematic problem. Based on his hydraulic schematic diagram, video of abnormal hydraulic column test run, AAK technical team had discussion and judged that the problem was still on the hydraulic pressure reducing valves. Liam said that their engineer tested the hydraulic pressure reducing valves separately and found no abnormality. I suggested that only by redesigning the hydraulic pressure reducing valve can the potential safety hazards of the hydraulic column be solved. Perhaps Liam was half convinced, maybe there was no other choice, he paid the development cost of the hydraulic pressure reducing valves. After 45 days, AAK sent the 20 newly designed hydraulic pressure reducing valves. 2 weeks later, Liam informed that the equipment had been running for 1 week, without noise, and the support was rising steadily. It could be delivered to the customer immediately. Their engineer wanted to know how AAK designed it. AAK newly designed hydraulic pressure reducing valve has the characteristics of high nominal pressure, large flow, good opening and closing characteristics, stable performance, reliable sealing, small volume and compact structure. We design and produce from the following 3 points, which is unexpected to most of our peers. 1. From joint, valve spool, valve spool sleeve, ejector rod, spring, base, valve body, axial hole and radial hole, from material selection to processing, we have made separate plans. 2. The axial hole is connected with the lower chamber of the column. The joint of the hydraulic pressure reducing valve is provided with an unloading channel. The radial hole of the valve spool can be connected with the unloading channel. The valve spool is connected with the spring through the ejector rod, the other end of the spring is connected with the base, and the joint is fixedly connected with the valve body. 3. A sealing ring is arranged between the valve spool and the inner wall of the joint, and an O-ring is arranged between the ejector rod and the joint. A special O-ring axial seal spring balance structure is adopted. Liam privately told that his boss had increased his salary for 2 levels and listed AAK as the preferred supplier of hydraulic pressure reducing valves. AAK hydraulic pressure reducing valves, unique design skills, high manufacturing quality, you can also try a small order! https://www.aakindustry.com/info-det , ail/hydraulic-pressure-reducing-valves- aak314
