Chinese Ball Valve Butterfly Valve and Auma SQ Series Part-turn Actuators with AM Control Unit

The AUMA SQ 05.2 – SQ 14.2 and SQR 05.2 – SQR 14.2 part-turn actuators with integral AUMA MATIC AM 01.1 / AMExC 01.1 controls (SFC version) deliver reliable 90° operation for quarter-turn valves. These compact, self-contained electric actuators combine a robust worm-gear mechanism with microprocessor-based controls for precise open-close and modulating duty. The SFC (Safety Figure Calculated) variant is specifically engineered for safety instrumented systems (SIS), providing certified safe end position feedback via mechanical limit switches. Available in standard and explosion-proof (Ex) versions, the system ensures long-term performance in harsh industrial environments with minimal maintenance.

• Compact Part-Turn Design: Direct mounting on valves with EN ISO 5211 flanges (F05 to F16), self-locking up to maximum torque.
• Integral AUMA MATIC Controls: Local selector switch (LOCAL-OFF-REMOTE), push buttons, and mechanical position indicator for easy operation.
• Functional Safety (SFC): Safe end position feedback with proven SIL capability; supports proof testing and Partial Valve Stroke Test (PVST).
• Robust Construction: IP68 enclosure (double-sealed option), corrosion protection KS/KX, wide temperature range.
• Torque & Limit Switching: Adjustable electro-mechanical switches for end positions and overload protection.
• Explosion-Proof Option: AMExC 01.1 for hazardous areas.

Ideal for automating butterfly, ball, and plug valves in water treatment, power generation, chemical processing, and oil & gas facilities. The SFC version is particularly suited for safety-critical applications requiring reliable end-position signaling in emergency shutdown systems.

• How do I verify safe end position feedback?
  Perform the proof test sequence: operate to end position, unseat, and re-seat while checking limit switch signals.
• Is the actuator self-locking?
  Yes for all standard speeds; no additional brake required up to maximum torque.
• What is the proof test interval?
  Defined by the plant operator; typically 1–5 years depending on PFDavg target.
• Can I use it in explosive atmospheres?
  Yes – select the AMExC 01.1 explosion-proof version.
• How to initiate PVST?
  Use local controls or external command; the system monitors actuator response dynamically.
