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 actuators with return spring PA-SA are designed for automation of industrial valves control process with maximum torque up to 2128 Nm.
The electropneumatic rotary positioner is used to control pneumatic rotary actuators by means of an electric controller or control system with analog DC output signal range from 4 to 20 mA.
