- Knife gate valve is Bi-directional, zero leakage, withstanding high differential pressure and full bore valve with minimal seat cavity for maximum 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 boday structure with precision casing.
- U-shaped resilient seat is embeded into the body and well connected with the gate, and the friction force is reduced during the upward and downwward movements of the gate.
- This greatly prolongs the using life of the seat and readized 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.

- Knife gate valve is widely used in urban sewage treatment, paper-making, mine slag discharge and the fields alike.
