Rotary pneumatic actuator (214531)

The pneumatic rotary actuator type 2051 has a linear piston actuator of one-way or two-way action, connected internally by a rod to a rotating element and equipped with a universal mechanical coupling device according to ISO 5211. When the piston moves linearly, the drive shaft rotates 90° due to the force of the control air pressure or the force of the return springs through the rod. This rotational movement can be used to actuate appropriate actuators, such as ball valves, flaps, etc. The actuator has an optical indication of the rotation position and does not require maintenance.
