Knife gate valve Knife Valves

with handwheel

Knife Valves are developed for sludge and abrasive applications; they are especially used in fluids containing abrasive particles. They perform their duties by opening and closing the fluid passage with a knife (slide) sliding between the two sealing rings perpendicular to the direction of passage. It is preferred to work fully open or fully closed. They are not suitable for precise flow control. Knife Valves are mostly suitable for use in fibrous fluids such as paper industry and waste water lines. It provides full sealing with its one-piece body and elastomer (EPDM, NBR, NR). Depending on the fluid properties, metal sitli can also be produced. With flywheel, gearbox, chain wheel, pneumatic actuator and electric actuator.
