Knife Gate Valve

A Knife Gate Valve is a component that is using a blade to cut through heavy liquid clogging, whereas a slide gate valve uses a slide plate to better manipulate or control the flow of dry bulk material. Knife gate valves were initially developed for use in the pulp and paper industry. Knife gate valves are mainly aimed for on-off and isolation services in systems with a high suspended solids content. Knife Gate Valves are notably useful in dealing with slurry, viscous, corrosive, and abrasive media. The valves have a low-pressure drop in the fully open position, are simple to operate, lightweight, and cost-effective. Knife gate valves are used only for applications in a completely open or completely closed position and should not be used to regulate flow unless specifically designed for it.
