The ductile iron wafer butterfly valve is a common type of valve, it has the characteristics of light weight, small flow resistance, easy to operate, good sealing performance, and good flow regulation performance, easy to install and maintain. The application field of cast iron wafer butterfly valve is wide, suitable for petroleum, chemical industry, light industry, urban gas, urban heating, water treatment and other industries, plays a role in cutting off and regulating, and is mainly used in normal temperature environment and low pressure, medium pressure places. Especially for drinking water butterfly valves, the rubber valve seat of wafer butterfly valve serves as the valve core and has been approved by WRAS and ACS, supporting drinking water projects.
