wcb knife gate valve

Carbon steel knife gate valve can produce fully lug、flange end or wafer end,which have shortly face to face dimensions,save space. WCB gate valve trade mark "THT", which belong to Tianjin Tanggu Jinbin Valve Co.,Ltd，for this kind of knife gate valve, our own design team, from product design, R & D, drawings and 3D drawings can be provided. The knife gate valve integral body with full bore structure ensures smooth flow, easy assembly and smaller shell leakage possibility. Guide claws design at the port bottom for gate fixture, instead of a groove, eliminates any potential clogging when valve shutoff.

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.
