Knife Gate Valve

Main Feature: The sealing surface can only be sealed by relying on the medium pressure, that is, the sealing surface of the ram is pressed to the seat on the other side by the medium pressure to ensure the sealing of the sealing surface, which is self-sealing. Most gate valves are forced to seal, that is, when the valve is closed, it is necessary to rely on external forces to force the gate to the seat to ensure the tightness of the sealing surface. This type of valve should generally be installed vertically in the pipeline.
