Rubber check valve is primarily used in water supply and drainage systems, as well as in petroleum, chemical, and other industrial sectors, to prevent medium backflow at the outlet of pipeline pumps. The sealing ring features an inclined design, which shortens the closing time and reduces water hammer pressure. The valve flap is made of nitrile oil-resistant rubber and steel plate pressed at high temperature, making it resistant to scouring and providing good sealing performance. Additionally, the product has a simple structure, which makes it convenient for maintenance, repair, and transportation.
