The 2051 pneumatic rotary drives are low maintenance single or double-acting pneumatic linear piston actuators where linear movement of the piston due to the pilot air causes a 90º rotation of the connected valve. Actuator-valve coupling is made via a universalI SO 5211 mechanical interface and the status of ball or butterfly valve can be monitore data control system through a range of rugged feedback switches. The drives can also be used as modulating control actuators by the addition of Bürkert’s range of Side Controlpositioners.
