The pneumatic triple offset hard-seal butterfly valve eliminates mechanical wear during opening/closing operations, providing excellent shut-off performance, long service life, and both regulating and shut-off functions.
Request a QuoteThe pneumatic triple offset hard-seal butterfly valve is developed from the double offset hard-seal butterfly valve by adding an angular offset (tapered conical sealing surface), forming the triple offset structure. This design eliminates mechanical wear and galling during opening/closing operations, with low closing torque, excellent shut-off performance, long service life, and both regulating and shut-off functions.
The WUYI series is widely used in automated control systems in petroleum, chemical, power, metallurgy, environmental protection, textile, and paper industries. It is suitable for isolating or regulating flow of liquids, gases, coal gas, natural gas, and steam.
