What is a Knife Gate Valve?
A knife gate valve is an industrial valve designed to handle abrasive slurries, fibrous materials, viscous fluids, and solid-laden media. Its sharpened blade-like gate cuts through thick materials to provide a positive shutoff and uninterrupted flow. These valves are ideal for industries where reliability under pressure isn’t optional — it's critical.
