Chinese Gate Globe Valve Body AUMA SA Multi-turn Electric Control Valve Actuators with AC Actuator Control Unit

The AUMA SA .2 series multi-turn actuators with AUMATIC AC 01.2 controls in SFC (Safety Figure Calculated) version are certified for use in safety instrumented systems (SIS) according to IEC 61508 / IEC 61511. They provide the “Safe end position feedback” safety function with proven SIL capability up to SIL 2/3 (low demand mode). The system combines reliable mechanical torque and limit switching with advanced diagnostics and EtherNet/IP communication, ensuring safe and monitored valve operation in critical applications.

• Functional Safety Certified: Safe end position feedback via mechanical switches; SIL 2/3 capability with calculated PFDavg and SFF values.
• Proof Test Support: Partial Valve Stroke Test (PVST) and full proof test procedures for regular verification.
• EMERGENCY Operation: Programmable reaction (stop, open, close, or intermediate position) with bypass options for torque and thermal protection.
• Comprehensive Diagnostics: Reaction monitoring, torque characteristics, operating data logging, and NAMUR NE 107 status signals.
• Self-Locking Design: Prevents uncontrolled valve movement from standstill up to maximum torque (for standard speeds).
• Robust for Safety Use: Wide temperature range, IP68 protection, and optional double-sealed terminal compartment.

Designed for safety-critical valve automation in oil & gas, chemical, power, and nuclear plants where emergency shutdown (ESD) or safety instrumented functions are required. Suitable for gate/globe valves in high-integrity pressure protection systems (HIPPS) and fire/gas detection loops.

• How often must I perform a proof test? Interval depends on PFDavg target; typically annual or every 2–5 years – see exida report for guidance.
• What is the safe end position feedback? Mechanical limit switches signal end position; hysteresis is minimal but must be considered in loop design.
• Can I use PVST for partial testing? Yes, programmable direction, stroke, and time; does not replace full proof test.
• Is the actuator suitable for high-demand mode? Only safe end position feedback under specific conditions; consult manual for limitations.
• How to verify SIL compliance? Use the provided exida report and perform site-specific verification per IEC 61511.
