Description
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-XXX double-acting pneumatic rotary actuators and PA-SA-XXX 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.
