What is a Knife Gate Valve?
Knife Gate Valves are developed for slurry and abrasive applications. They are commonly used in applications containing abrasive particles. These valves are called knife gate valves because they cut off the flow with a blade (gate) perpendicular to the flow. This blade operates by closing and opening vertically between two sealing rings. They are preferred to operate either fully open or fully closed. They are not suitable for precise flow control.
Knife gate valves are suitable for highly fibrous fluids, such as the paper industry and wastewater lines. With their one-piece body and elastomer (EPDM, NBR, NR) seats, they provide complete sealing. Depending on the fluid characteristics, they can also be produced with metal-seated options. They can be equipped with handwheel, gearboxes, chain wheels, pneumatic actuators, and electric actuators.
