5.1. Designated application area
The pneumatic rotary actuator type 2051 is designed for the actuation
of rotary valves, such as ball or butterfly valves.
5.2. General description
Fig. 1: Pneumatic rotary actuator
Type 2051
The pneumatic rotary actuator Type 2051 consists of a single or double-
acting linear actuator with an internal coupling to a rotary piece and an
universal interface as per ISO 5211. During the linear movements of
the pistons through the pressure force of the control air and the force
of the resetting springs, the drive shaft is turned via the coupling. This
rotary movement can be used for the actuation of respective control
elements, such as ball or butterfly valves.
