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 done by turning the handle counterclockwise, closing - clockwise.
Pneumatic Elephant 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.
Limit switch unit is designed for visual and electrical signaling of end positions of the valve shut-off body: valve, tap or disk gate. It is mounted on top of the pneumatic actuator surface and is connected to the actuator shaft in DIN standard. The sealed box usually contains two sensors, which monitor the position of the actuator shaft and signalize in extreme positions. OMRON microswitches, inductive sensors or reed switches are used as sensors.
