How it works

Spring-return rotary actuator

Butterfly disc

5/2 double-solenoid pilot

5/2 double-solenoid pilot: Both coils off — **Both coils off**The spool keeps its last position; the drawing retains the coil-14 example.

The number that matters

Nominal pressure

10bar

The pressure class of the valve body at 20 °C. Working limits depend on the medium and its temperature.

Applications

Media and industries

Water
Steam
Neutral Media
Food Industry

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. Operating principle: The valves are opened and closed by turning the disk by 90°. Opening is performed by turning the handle counterclockwise, closing - clockwise.
Pneumatic DNOVA pneumatic double-acting rotary actuators PA-DA-XXX and pneumatic rotary actuators with return spring PA-SA-XXX are designed for automation of industrial valves control process with maximum torque up to 2128 Nm.
Pneumatic valves are used to change the direction, start, stop the compressed air flow in the pneumatic system depending on the external control action.
