Knife Gate Valve is used to slice through sludge or sewerage and a gate is used fro normal positive shut off .It is a gate valve design that is distinguished from the standard design by the use of a simple metal plate for the gate and the absence of a bonnet; also called a slide valve.
Knife gate valve is a uni-directional or bi-directional valve designed for general industrial service applications. Knife gate valves used for pressure tight isolation of solid-liquid mixes in water and waste water treatment plants and pumping stations, paper and pulp plants, power plants and mining industry.
