Pneumatic rotary drive

Transcription

1 Pneumatic rotary drive Modular program for mounting of quarter turn valves such as ball valves and butterfly valves NMUR and ISO 5211 interfaces Position feedback (including Ex-Versions) Type 2051 can be combined with Sideontrol Positioner ready Type 6518/6519 Type 892/89 Type 265 Solenoid valve Positioner Sideontrol Stainless steel ball valve Position feedback Metal butterfly valve 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 90 rotation of the connected valve. ctuator-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 urkert s range of Sideontrol positioners. ontrol function Single-acting actuator return by spring, operating e.g. with pilot valve P Technical data Materials ctuator Piston Seal ontrol medium ontrol pressure T umg Rotation djustable angle every 20 Interface Pilot air ports Feedback signal Fittings aluminium alloy aluminium buna-n filtered compressed air with or without oil PSI (-8 bar) max allowable working pressure 15 PSI (10 bar) max operating pressure 116 PSI (8 bar) -0 F up to 200 F (-0 up to +9 ) 90, adjustable ±5 of valve travel NMUR Flange interface VE/VI 85 G ¼" NMUR VE/VI 85 ISO 5211 ontrol function I ouble-acting actuator, operating e.g. with pilot valve P ontrol function Single-acting actuator return by spring See page for function principles usa.com p. 1/9

4 Functional principle ontrol function ir supplied to port P1 forces the pistons toward the actuator end caps, compressing the springs. 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 pistons inward. clockwise rotation is achieved. Exhaust air exits from port P2. P2 P1 P2 P1 P2 P1 ontrol function I ir supplied to port P1 forces the pistons towards the actuator end caps. counterclockwise rotation is achieved. Exhaust air exits from port P2. ir supplied to port P1 forces the pistons inward. clockwise rotation is achieved. Exhaust air exits from port P2. P2 P1 P2 P1 P2 P1 Travel djustment Travel djustment Range Range ctuators feature bidirectional pinion travel stops. Side located stops allow a full +5 of valve travel adjustment, giving a guaranteed range of adjustment 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 recommended stroke speed Standard ssembly djustment 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 p. /9
