Double acting pneumatic knife gate valve
Double acting pneumatic knife gate valves are suit for any abrasive medium and operated by double acting pneumatic .
Double acting pneumatic knife gate valves are composed of double acting pneumatic actuator and knife gate valve. They are used on industrial pipeline for on-off operation. The structure of body and seat eliminates clogging shutoff for flow with fine particles.The disc bottom of knife gate valve is made into a blade shape with the purpose to cut some soft materials such as fiber,pulp or wood pulp, and it also serves favorable closing and opening.
Features:
- knife gate valve is composed of narrow body and sliding gate.
- The gate has sharp blade that can separated or cut the solid particles in the fluid media.
- The polishing treatment on the gate surface strengthens its penetrating power and effectively guarantees the service life of both packing and valve seat.
- The bottom of valve body is provided with the gate hold down device that can safely pressure the gate tightly on the valve seat in order to ensure valid tight-seal.
- Double acting type pneumatic actuator can save the labor cost largely .
