The rubber flap check valve is mainly used at the pump outlet of drainage systems, petrochemical, metallurgy, and other industrial sectors to prevent backflow of the medium. This valve can also be installed on the bypass pipe of the inlet and outlet water pipes of a reservoir to prevent backflow of pool water that could damage the pump. Due to the inclined design of the sealing ring, the closing time is short, which can reduce water hammer pressure. The valve flap is made of oil-resistant nitrile rubber and steel plate pressed at high temperatures, making it resistant to impact and providing good sealing performance. The product has a simple structure, making maintenance, repair, and transportation very convenient, with reliable sealing performance achieving bi-directional sealing with zero leakage.
