Knife Gate Valves
Knife Gate Valves are designed to control the isolation of process fluids that contain suspended solids, slurries or viscous material. The term ‘knife gate’ refers to the disc that cuts through the process media and closes the valve. The ‘knife’ or disc is also pushed against a sealing face to form a seal and prevent flow.
Knife Gate Valves minimise pressure drop across the valve in the fully opened position and stop the flow of fluid completely.
Knife Gate Valves are ideal for bidirectional, low-friction flow and 100% shut-off and are advantageous in applications involving slurries and applications that involve viscous liquids such as heavy oils, light grease & varnish. They are used in industries such as Oil & Gas, Water, Waste-water and Irrigation, Sludge, Steam and Mining.
