lug knife gate valve

This series standard, lug type wafer knife gate vale are suitable for the sewage treatment, the chemical industry, the manufacture paper pulp industry and the mining industry ,coal washingndustry, to circulates the medium for pipeline in and so on liquid suspending iquidze plays cuts off and clears the role.

WCB manual operated lug Knife Gate Valve is Bi-directional, Zero Leakage, withstanding high differential pressure and full bore Valve with minimal seat cavity for maximun flow capactiy. No groove is designed on the valve seat, it can prevents accumulating media on the sealing surface. And thus avoids sealing surface leakage or disc blockage caused by media accumulation. This kind of knife gate valve integrated body structure with precision casing. The U-shaped resilient seat of knife gate valve is embeded into the body and is well-connected with the gate, and the friction force is reduced during the upard and downward movements of the gate. This greatly prolongs the using life of the seat and realizes bi-directional sealing.
