Knife Gate Valves

A Knife Gate Valve is a valve that controls the flow by lowering a metal wall (the knife) down across the flow path. A Knife Gate Valve operates like a guillotine with a sharp edge that slices through the media. This makes it ideal for media with soft suspended solids. They are very common in mining and metals industries as they are able to simply cut through any material that is preventing them from closing. Knife Gate Valves are suitable for large flow applications, particularly those with suspended solids that could be caught between the disc and the seat or wrapped around the disc in Butterfly Valves.
