AUMA SA SQ Modulating Electric Actuator,4‑20mA Signal High Precision for Pipeline Automation Power Plant Industrial Valve

The AUMA SA/SQ Electric Actuator combined with a Chinese Electric Valve offers a high-performance solution for automated valve control in demanding industrial environments. The AUMA SA (multi-turn) and SQ (part-turn) actuators are renowned for their reliability, delivering precise torque and positioning for gate, globe, ball, and butterfly valves. Paired with a robust Chinese electric valve, designed for tight shut-off and efficient flow control, this combination ensures seamless operation in applications such as oil and gas, chemical processing, and water treatment. With advanced diagnostics, modular design, and compliance with international standards like ISO and DIN, this product duo provides dependable automation and long-term durability.

• Versatile Actuation: AUMA SA for multi-turn (10–32,000 Nm) and SQ for part-turn (50–2,500 Nm) valves, ensuring compatibility with diverse valve types.
• Precision Control: Advanced limit and torque sensing for accurate valve positioning and operation.
• Robust Valve Design: Chinese electric valve with pressure-balanced or single-seat options for tight shut-off and high flow capacity.
• Advanced Diagnostics: AUMA AC controls with time-stamped event reports, torque logging, and vibration monitoring for predictive maintenance.
• Modular Design: Flexible configurations with AUMA plug/socket connectors and optional fieldbus interfaces (e.g., Profibus, Modbus).
• High Durability: IP68 enclosure protection and corrosion-resistant materials (stainless steel, carbon steel for valve; aluminum for actuator).
• Manual Override: Handwheel for manual operation during power outages or maintenance.
• Wide Compatibility: Supports 3-phase, 1-phase AC, and DC motors for global applicability.
• Certifications: Compliant with ISO 5210/5211, DIN, ATEX, and SIL 2 (for select configurations).
• Easy Integration: Seamless connection to DCS via AUMA’s configurable interfaces and Bluetooth-enabled CDT software.

The AUMA SA/SQ Electric Actuator and Chinese Electric Valve combination is designed for robust automation in critical industrial applications:

• Oil and Gas: Precise control of gate and ball valves in pipelines and refineries.
• Chemical Processing: Regulates flow in reactors, distillation columns, and chemical dosing systems.
• Water Treatment: Automates valves in municipal water supply and wastewater treatment plants.
• Power Generation: Manages steam, water, or gas flow in boiler and turbine systems.
• Petrochemical Industry: Ensures reliable operation in high-pressure and corrosive environments.

The AUMA SA supports multi-turn valves (gate, globe), while the SQ supports part-turn valves (ball, butterfly), paired with Chinese electric valves of various types.

They provide precise torque control, advanced diagnostics, and fieldbus integration for seamless automation and monitoring.

Yes, with IP68 protection, corrosion-resistant materials, and ATEX certification, it’s suitable for extreme conditions.

It reduces actuator force requirements, enabling efficient control in high-pressure differential applications.

AUMA’s modular design, diagnostic tools, and manual override, combined with the valve’s robust construction, minimize downtime and servicing needs.
