Flanged Butterfly Valve Body Casting Double Sand Casting Iron QT450-10
Description
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.
It is widely utilized in foodstuff, pharmacy, chemical industry etc. and industrial environmental protection, water treatment, high building, water supply and drain tubing line open or close or adjusting medium.
We can make weld butterfly valve, wafer butterfly valve, flange butterfly valve we supply different body / disc materials such as cast iron, cast steel, stainless steel and bronze according to different working conditions.
