The knife gate valve, also known as a knife-shaped gate valve, knife gate valve, or slurry valve, features a uniquely designed blade-like, beveled gate disc. This specialized design enables it to easily cut through and handle viscous or scaling media containing solid particles, fibers, slurries, and other challenging materials. It is widely used in demanding applications where conventional valves are prone to blocking and leakage.
