www.burkert–usa.com p. 1/9 Pneumatic rotary drive The 2051 pneumatic rotary drives are low maintenance single or double-acting pneu- matic linear piston actuators where linear movement of the piston due to the pilot air causes a 90° rotation of the connected valve. Actuator-valve coupling is made via a universal ISO 5211 mechanical interface and the status of ball or butterfly valve can be monitored at a control system through a range of rugged feedback switches. The drives can also be used as modulating control actuators by the addition of Burkert’s range of SideControl positioners. Type 2051 can be combined with…

p. 4/9 Functional principle P2 P1 P2 P1 P2 P1 P2 P1 Control function A Air supplied to port P1 forces the pistons toward the actuator end caps, compressing the springs. A counter-clockwise rotation is achieved. Exhaust air exits from port P2. The loss of air pressure (air or electric failure) at port P1 allows the springs to force the pis- tons inward. A clockwise rotation is achieved. Exhaust air exits from port P2. Control function I Air supplied to port P1 forces the pistons towards the actuator end caps. A counterclockwise rotation is achieved. Exhaust air exits from port P2. Air supplied to port P1 forces the pistons in- ward. A clockwise rotation is achieved. Exhaust air exits from port P2. P2 P1 P2 P1 P2 P1 P2 P1 Actuators feature bidirectional pinion travel stops. Side located stops allow a full +5˚ of valve travel adjustment, giving a guaranteed range of adjust- ment between 80˚ and 100˚ of actuator travel. These travel stops are designed to absorb the maximum rated torque of the actuator and the maximum impact loads associated with recom- mended stroke speed. Standard Assembly Adjustment of the counterclockwise and clockwise rotation limits are accomplished by turning the respective left and right stop adjustment screws to reduce or increase output rotation. Travel Adjustment Range 100° -5° +5° -5° +5° 90° 80° Travel Adjustment Range
