Function Description
The actuator is a pneumatic twin-piston drive, designed primarily for operating ball valves and butterfly valves. A double-action and a spring-return (single-action) type are available. The twin-pistons provides high torque in a compact system. The rotation angle is adjustable by ±6° from the standard setting.
Design
Due to the twin-piston system the force developed by the counter-running pistons is transmitted to one common pinion via two tooth racks solidly connected with the pistons. This principle ensures a linear torque transmission along the entire stroke. The integrated spring packages of the single-acting actuators enable, in addition to a simple control, the rotation into a predefined position when the control pressure air or the control voltage fails (failsafe).
