Chinese Globe Valve Body AUMA SA Multi-turn Electric Control Valve Actuators with AC Control Unit
The AUMA SA 07.2 – SA 16.2 multi-turn actuators with AUMATIC AC 01.2 actuator controls (EtherNet/IP version) form a robust, intelligent electric actuator system for precise open-close and modulating duty on industrial valves. Designed for 3-phase AC motors, the system delivers reliable torque output from 10 Nm to 1,000 Nm across a wide speed range. The AC 01.2 controls provide advanced EtherNet/IP fieldbus integration, local operation via graphic display and push buttons, and comprehensive diagnostics. The SFC (Safety Figure Calculated) variant supports functional safety applications up to SIL 2/3 with safe end position feedback. Suitable for both indoor and outdoor use in harsh environments, the system ensures long service life with minimal maintenance.
- High-Performance Actuation: Self-locking up to 90 rpm (50 Hz) or 108 rpm (60 Hz); adjustable torque switching for OPEN/CLOSE directions.
- EtherNet/IP Communication: Full integration with star topology, 100 Mbit/s transmission, cyclic I/O (46 bytes input/14 bytes output) and acyclic messaging.
- Advanced Local Controls: Selector switch (LOCAL-OFF-REMOTE), push buttons, illuminated graphic LC display, and Bluetooth interface for wireless commissioning.
- Comprehensive Diagnostics: Torque characteristics recording, operating data logging, NAMUR NE 107 status signals, and Partial Valve Stroke Test (PVST).
- Safety Functions: Safe end position feedback via mechanical switches; EMERGENCY operation with programmable reaction; thermal motor protection.
- Robust Design: IP68 enclosure (up to 8 m water depth for 96 hours), corrosion protection KS/KX, wide temperature range –50 °C to +80 °C.

Ideal for open-close and modulating control of gate, globe, and butterfly valves in power plants, water treatment, oil & gas pipelines, and chemical processing. The EtherNet/IP interface enables seamless integration into modern DCS/PLC systems, while the safety functions support emergency shutdown and safety instrumented systems (SIS) in critical processes.
- How do I perform a Partial Valve Stroke Test? Use the local display or EtherNet/IP to initiate PVST; the system automatically checks actuator and valve function without full stroke.
- What happens during loss of communication? Programmable behaviour: stop, move to end position, or last command (configurable via AC 01.2 settings).
- Is the actuator self-locking? Yes for speeds up to 90 rpm (50 Hz); higher speeds require additional measures.
- How to set torque limits? Adjust via local controls or AUMA CDT software; limits are independently set for OPEN and CLOSE.
- Can I use it in hazardous areas? Yes, with appropriate Ex version (SAEx/ACExC) certified for explosive atmospheres.
