Carbon steel swing check valve

Swing check valve is suitable for water, steam, oil, gas and weak corrosive media, widely used in petroleum, chemical, electric power, metallurgy and other industries in low and medium pressure piping system. The valve uses the valve flap to rotate around the axis of opening and closing, low resistance, suitable for large flow, low-frequency opening and closing conditions. The working temperature range is generally -29℃ to +550℃, depending on the material. The main function is to prevent backflow of media and protect equipment safety. Commonly used materials include carbon steel, stainless steel, alloy steel, sealing surface can be stainless steel or carbide, with good sealing and durability.
