Product Introduction
Introduction:
Bare shaft butterfly valve is divided into two types of sealing: soft seal and hard seal. Soft-sealed polished stem butterfly valves are commonly used in wafer type, lug type, flange type and groove type. Hard-sealed polished stem butterfly valves are commonly used in wafer type, lug type, flange type and welded type.
Application:
Bare shaft butterfly valve is widely used in metallurgy, petrochemical, chemical refining, water supply and drainage engineering and other industries.
