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.
