Product Overview
Knife gate valves can be equipped with electric actuators and pneumatic actuators. By using accessories such as solenoid valves and proximity switches, they can achieve action control and signal output at the open and closed positions, and also perform automatic control of continuous actions. Users can make a choice according to their actual needs. It is widely used in fields such as chemical engineering, coal, sugar refining, sewage treatment, and papermaking, and is an ideal sealing valve. It is particularly suitable for use in the papermaking industry for regulation and throttling on pipelines.
