Knife Gate Valves
Knife gate valves are designed to provide optimal performance in heavy applications within the paper, oil, and mining industry. For example, when a possible accumulation of foreign materials does not allow the use of conventional shut-off valves, the knife gate valve is the right solution.

Features of Soft Seal Knife Gate Valves:
1, Utilizing position limited device to prevent the valve from being over-opened or closed.
2, Grease device is installed for injecting grease to reduce part wear and operation torque.
3, Lugs are designed on the yoke for installing pin and lock to prevent unauthorized operation.
4, Blade side round–shape configuration greatly reduces packing wear during operation, improves the sealing performance, and extends valve service life.
Features of Metal Seal Knife Gate Valves:
1, Grease device is installed for injecting grease to reduce part wear and operation torque.
2, Lugs are designed on the yoke for installing pin and lock to prevent unauthorized operation.
3, Blade side round-shape configuration greatly reduces packing wear during operation, improves the sealing performance, and extends valve service life.
4, Stoppers are designed to prevent blades from being over closed.
