AUMA SQ 05.2-14.2 Part-Turn Actuator with AM 01.1 Controls SFC Safe End Position Feedback Valve

AUMA SQ.2 / SQR.2 part-turn actuators with integral AM 01.1 / AMExC 01.1 actuator controls (SFC version) are robust, self-locking electric actuators designed for precise 90° operation of industrial valves. Available in sizes SQ 05.2–SQ 14.2 (and explosion-proof SQEx / SQREx equivalents), they deliver reliable open/close or modulating duty while supporting functional safety requirements to IEC 61508 / IEC 61511. The SFC designation confirms that safety figures have been calculated via FMEDA for the “Safe end position feedback" safety function.

• Integral AUMA MATIC controls (AM 01.1 / AMExC 01.1) with plug/socket connector
• Safe end position feedback via directly wired mechanical limit switches (safety-related signal path only)
• Self-locking design prevents uncontrolled valve movement under load
• Suitable for low-demand mode; limited high-demand capability under strict conditions
• Hardware fault tolerance HFT = 0; Type A device classification
• Wide range of duty types (S2-15 min, S2-30 min, S4-25 %, S4-50 %)
• Optional explosion-proof versions (SQEx / SQREx + AMExC)
• Mechanical position indicator and robust enclosure options

Industrial process valves requiring functional safety (SIS), on/off and modulating control in oil & gas, chemical, water treatment, power generation, and general industry. Suitable for both standard and hazardous areas (Ex versions).
