Wafer Type Cast Iron Butterfly Valve
The butterfly valve is used for throttling or shutting off the flow of corrosive or non corrosive gased, liquids and semi liquid. It can be installed in any selected position in pipelines in the industries of petroleum processing, chemicals, food, medicine, textile, paper making, hydroelectricity engineering, building, water supply and sewage, metallurgy, energy engineering as well as light industry.
The butterfly valve use ductile iron material with good casting performance, low cost, convenient production
The butterfly valve use EPDM for sealing material more resistance to acid, alkali, water, superheated water, and water vapor; resistance to polar oil
