Knife Gate Valves

Valves for controlling viscous fluids and abrasive media in fluids

KLINGER Knife gate valves are used in cement plants, wastewater treatment plants, chemical plants, mining, and in many more industrial applications.

Gate valves are designed mainly for on-off and isolation services, however, if the fluid is of a viscous nature, a special type of gate valve known as a knife gate valve is recommended. Gate valves used in the mainlines carrying oil or gas must be of full bore or through conduit design to enable smooth passage of scrapers or pigs used for cleaning or monitoring pipelines.

KLINGER Knife Gate Valves are characterized by an interior blade that rises and falls by means of a shank. This operating principle allows it to efficiently “cut” the fluid. Knife gate valves are ideal for systems that transport fluids with a high solids content, which are difficult or impossible to close by means of conventional valves.
