Explosion-proof electric butterfly valve material requirements

Explosion-proof electric butterfly valve selection is three eccentricity elastic sealing ring and sealing structure design, has excellent sealing function, it is widely used in petrochemical, electric power, metallurgy and other professional industrial piping. This makes explosion-proof electric butterfly valve needs time to face a variety of different working environment, so the production of its data request is appropriate. Explosion-proof electric butterfly valve body and valve plate is chosen as basic information, for the WCB carbon steel, alloy steel, stainless steel with high hardness, wear resistance and other properties, such as information, make its can easily deal with all kinds of working condition of the environment, the valve spindle is usually choose 2 cr13 stainless steel and alloy steel materials to ensure the strength and seal materials are stainless steel, high temperature or low temperature can adhere to the good sealing and packing using flexible graphite. That is the request of the explosion-proof electric butterfly valve on the production data. Electric valve
