manual operated knife gate valve

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.

1. It adopts the wafer structure, small volume and light weight. 2. The fully open channel can prevent the medium from depositing in the valve. 3. The newly developed U-ring can ensure the good sealing performance of the valve.
