Polyurethane valve seals as very precise nonstandard or standard mechanical parts are made from superior quality polyurethane materials of proper hardness from well known companies in the world like Yantai Wanhua Chemicals and with a big variety of designs,colors and sizes available for option.Also can be customized according to buyers' special requirements.They are the special sealing parts for some valves.
To lose a large amount of money in the Hydraulic Flow Control Valve, AAK used a small amount of money to ease the worries of Brazilian customer
Bernardo comes from a hydraulic winch manufacturer in Brazil, and has cooperated with AAK several times on non-standard customized hydraulic cartridge valves. At the beginning of last year, Bernard company needed to purchase hydraulic flow control valves for a batch of hydraulic winches. Due to cost pressure, the boss asked Bernard to reduce the procurement cost of hydraulic flow control valves by 10%. This hydraulic flow control valve needs to be the same as HydraForce standard part. After a round of sourcing, Bernard determined the manufacturer of the hydraulic flow control valve. 7 months after the sale of the hydraulic winch, a customer complained that the sealing ring of the hydraulic flow control valve was broken, resulting in leakage, which caused the hydraulic winch to rise powerlessly. 6 months after the original manufacturer replaced the sealing ring with new one, the old problem happened again. The customer complained directly to the boss, who asked Bernard to replace all the hydraulic flow control valves within 1 month and asked the original manufacturer to bear the costs. However, the original manufacturer could not reach an agreement. Bernard was caught in the middle. He was embarrassed for 2 weeks and made no progress. The boss was very disappointed with him.
Bernard sent me an email asking about the time and cost of re producing the hydraulic flow control valves. He wanted to pay for it himself. According to the hydraulic flow control valve drawings he sent, I realized that maybe only replacing with durable O-ring could solve his embarrassment. I sent him 10 O-rings for matching tests. A week later, Bernard told me that AAK O-rings could be matched with the original manufacturer's hydraulic flow control valves. He asked me to send 500 O-rings to Brazil as soon as possible, and he could finally have a good sleep.
Last week, Bernard sent an e-mail to express his thanks. All these hydraulic flow control valves have been assembled with AAK O-rings. It has been more than a year, and there has been no complaint of leakage caused by the rupture of the sealing ring of the hydraulic flow control valves. The boss also praised him for solving big losses with small money.
AAK's O-ring has 3 strengths: no sloughing, no extrusion and wear resistance. The material and structure of the seal ring directly affect the performance of the seal ring. The hardness, extrusion resistance, tensile strength and deformation of the material all determine the service life of the seal ring, and the structure of the seal ring also determines the sealing effect. AAK selects Japan's special PU polyurethane rubber sealing ring, and the lip compression of the sealing ring is strictly controlled between 15% ~ 20%.
