A knife gate valve is a type of valve that uses a sharp-edged gate to cut through and control the flow of fluids. Slide gate valves are generally used below silos, tanks, conveyors, and hoppers. The sliding gate allows controlling the gravitational flow of granular materials. Carbon steel, stainless steel, and hardox steel construction are available for slide gate valves for a wide range of applications.
