It is mainly used in the pipeline outlet of water supply and drainage system, petroleum, chemical industry and other industrial sectors to prevent reverse flow of medium. Due to the inclined design of the sealing ring of this product, the closing time is short, which can reduce the water hammer pressure. The valve disc is made of nitrile rubber and steel plate by high temperature pressing. It is resistant to erosion and has good sealing performance. The product structure is simple, maintenance, repair and transportation are very convenient.
