Type 2051 – Pneumatic rotary actuator

Type Description
The Type 2051 pneumatic rotary actuators 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 universal ISO 5211 mechanical interface. The status of ball or butterfly valve can be monitored via the feedback switches of 1061. Moreover the actuator can be used as modulating control actuator by the addition of Bürkert’s range of Side Control positioners 8792/3.
