Pneumatic Actuator Wafer Connection Hard Seal Double Flanged Triple
Eccentric Butterfly Valve
Butterfly valve, including lug type, wafer type, flange type and triple eccentric
type that has been produced in TEYI enterprise is professionally
designed, the lug and wafer type butterfly valves are designed for
shutoff and isolation service of liquids and gases. Thin profile,
center disc provides high flow capacity and the body wall thickness
confirms to the requirement of ANSI class 125 and AWWA standards.
Triple eccentric butterfly valve series is the newly developed long
life time and energy saving products, the sealing is metal to metal
or seal ring to metal, stainless steel plate and composite graphite
to metal, which is suitable for working condition of high
temperature and high pressure. Triple eccentric butterfly valve is
widely used in petroleum, natural gas, piped gas and medicine food
