Butterfly valves are designed for use as shut-off or regulating valves for controlling flows in heat supply systems, water supply systems, in technological processes of food, chemical, oil and gas, pulp and paper and other industries. The valves are opened and closed by turning the disk by 90°. Opening is performed by turning the handle counterclockwise, closing - clockwise.
Pneumatic rotary actuator is designed to automate the process of control of industrial valves, as well as to determine the position of the valve shut-off body.
Pneumatic valve is used to change the direction, start, stop the compressed air flow in the pneumatic system depending on the external control action.
