Chinese Globe Valve Body Control Valve AUMA SA SAR Multi-turn Electric Control Valve Actuators
AUMA's SA 07.1 – SA 16.1 and SAR 07.1 – SAR 16.1 are multi-turn electric actuators designed for automating industrial valves, particularly gate and globe valves requiring full revolutions. The SA series is optimized for open-close duty (short-time S2), while SAR supports modulating duty (intermittent S4/S5). In the AUMA NORM version (without integral controls), they are driven by a 3-phase AC motor, featuring self-locking worm gearing to withstand thrust and transmit torque. These actuators include manual handwheel operation for emergencies and are built for reliable performance in harsh environments, with options for explosion-proof applications in dust zone 22. They comply with EN ISO 5210 standards and are certified under EC Directives for machinery, EMC, and low voltage.
- Versatile Duty Types: SA for short-time open-close (S2 - 15/30 min), SAR for intermittent modulating (S4 - 25/50%, S5 - 25%) with up to 1,500 starts per hour.
- Torque and Limit Control: Adjustable torque switching for OPEN/CLOSE directions; limit switching with single, tandem, or triple switches (galvanically isolated options).
- Manual Operation: Lockable handwheel that does not rotate during motor operation; engages/disengages easily for emergency use.
- Feedback Options: Analogue position/torque signals (0/4-20 mA via RWG); mechanical position indicator; running indication via blinker.
- Protection Mechanisms: Motor thermoswitches or PTC thermistors; overload protection; automatic phase correction for 3-phase supply.
- Environmental Resilience: IP67/IP68 enclosure (submersion up to 8m/96 hours); vibration resistance 2g (10-200 Hz); KS/KX corrosion protection for moderate/extreme pollutants.
- Assembly Flexibility: Various output drives (A, B1-B4, E) per EN ISO 5210/DIN 3210; stem nut machining for custom fits; accessories like stem protection tubes.

Suitable for industrial valves in water/power plants, wastewater treatment, and chemical industries. SA for open-close duties in pipelines/tanks; SAR for modulating flow/pressure control. Approved for Ex zone 22 dust areas (option); indoor/outdoor use with low to high pollutant concentrations. Not for continuous operation, buried service, permanent submersion, or gas explosive zones (use Ex variants).
- What is the difference between SA and SAR? SA is for open-close (short-time duty), SAR for modulating (intermittent duty with higher starts).
- How to set torque switching? Open switch compartment, adjust dials for OPEN/CLOSE; refer to page 24 in manual.
- Can it handle wrong phase sequence? Yes, automatic correction for 3-phase AC supply.
- What if fault during commissioning? Check rotation direction (page 27), limit switching (page 28), or motor protection tripping (page 32).
- How to store? Dry, well-ventilated; max 2 years; refer to page 8.
