GGG40 GGG50 Wras Ductile Iron Double Eccentric Butterfly Valve With PN10 PN16 PN20 PN25

Series No. BFV-1001

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.
