Product Details

    wafer type butterfly valves are widely used in water conservancy projects, urban water supply and drainage, sewage treatment, electric power, petroleum, petrochemical, heating, shipbuilding, pharmaceutical, metallurgical and other industries. it is a device used to adjust or cut off the media in the pipe.

    butterfly valve is mainly consisted of body, stem, disc, seat and driver(lever,  gearbox, pneumatic  and electric  actuator)  and so on. 

    on off and controlling flow of valve are made by turning stem and disc together.
