  • 100% Original Lug Type Butterfly Valve With Lever Operator - Top Mounted Eccentric Half-Ball Valves – CVG

    100% Original Lug Type Butterfly Valve With Lever Operator - Top Mounted Eccentric Half-Ball Valves – CVG

    Features ▪ Small pressure loss: when fully opened, the water loss is zero, the flow channel is completely unblocked, and the medium will not deposit in the cavity of the valve body. ▪ Resistance to particle wear: there is a shear effect between the V-shaped opening ball crown and the metal valve seat. In the closing process, the ball crown only leans towards the valve seat at the last moment, without friction. Moreover, the valve seat is made of wear-resistant nickel alloy, which is not easy ...
