Product Introduction
Introduction of Ductile iron butterfly valve:
Ductile iron butterfly valve is a kind of general soft sealing butterfly valve, such as: middle-line soft sealing butterfly valve, lug soft sealing butterfly valve, U-type soft sealing butterfly valve, flange lining rubber soft sealing butterfly valve, double eccentric soft sealing flange butterfly valve and single eccentric soft sealing flange butterfly valve and other products.
Application:
It is suitable for tap water, sewage, construction, petroleum, chemical, food, medicine, light textile, electric power, shipping, metallurgy, energy systems, etc.
Description:
Ductile iron butterfly valve advantages:
Compared with gray cast iron material, it is equipped with high tensile strength, high yield, and ball mill cast iron material will not appear fracture phenomenon. Compared with cast steel, its' corrosion resistance and oxidation resistance are higher than cast steel, and the material cost is lower than cast steel's. Therefore, unless any special working conditions, it is more favored by users.
