Optional End connection: Wafer, Lug, Flanged.
Face to face: EN558 Series 13/14, long type or short type
Normal diameter: 4″~96″ (DN100~DN2400).
Pressure range: 150lbs? (PN10~PN25).
Available Operation: Gearbox, Electric, pneumatic actuator
Working temperature: -46℃~+200℃.
?
Performance:
Double Eccentric flanged butterfly valves, the axis of the valve stem deviates from the center of the butterfly plate and the center of the body. The effect of double eccentricity enables the butterfly plate to quickly detach from the seat after the valve is opened, which greatly eliminates unnecessary excessive squeezing and scraping between the butterfly plate and the valve seat, reduces the opening resistance, reduces wear and improve Seat life.
?
Application:
The double eccentric butterfly valve uses an eccentric structure design, which is widely used in the fluid piping system of water supply and drainage, sewage, construction, petroleum, chemical industry, textile, papermaking, hydropower, metallurgy, energy and other projects for regulation and interception.
