How it works

Double-acting rotary actuator

Butterfly disc

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
Food environment
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.

PA-DA double-acting pneumatic rotary actuators and PA-SA double-acting pneumatic rotary actuators with return spring are designed to automate the process of controlling industrial valves with maximum torque up to 2128 Nm.
