● Knife gate valve is Bi-directional, Zero Leakage, withstanding high differential pressure and full bore valve with minimal seat cavity for maximun flow capacity.
● No groove is designed on the valve seat, which prevents accumulating media on the
sealing surface. and thus avoids sealing surface leakage or disc blockage caused by media accumulation.
● The integrated body structure with precision casing.
● U-shaped resilient seat is embeded into the body and is well-connected with the gate, and the friction force is reduced during the upward and downward movements of the gate. This greatly prolongs the using life of the seat and realizes bi-directional sealing.
● The rubber O-ring is embeded into the flange groove, which makes it convenient to connect the valve to pipe and provides reliable sealing.
