Knife Gate Valves
A Knife Gate Valves, also known as a sluice valve, is a Valve that opens by raising a round or rectangular gate/wedge out of the
route of the fluid. Knife Gate Valves are purposely designed to start or stop the flow, and when least flow restraints are needed. In
working, these Valves commonly are either fully opened or fully closed.
Valve Types:
Through Going Knife Gate Valves.
EN Wafer Knife Gate Valves.
Wafer Knife Gate Valves.
Mono-Block Knife Gate Valves.
Fully Lugged Knife Gate Valves.
Advantages of Knife Gate Valves:
Excellent Restriction specialties.
Bidirectional so they can be used in two directions.
Pressure loss through the Valves is minimum
Limitations of Knife Gate Valves:
They cannot be opened or closed instantly.
Not suitable to control or throttle flow.
Vibration sensitive in Open Environment.
