Sipos 2SQ7 Part-turn Actuators Rotary Actuators 2SA7 Sipos Electric Control Valve

The Sipos 2SQ7 Part-turn Rotary Actuator is a high-performance electric actuator designed for precise and reliable control of quarter-turn valves such as ball valves, butterfly valves, and dampers.
Manufactured by SIPOS Aktorik (a Siemens company), the 2SQ7 series combines intelligent control electronics with robust mechanical engineering, delivering long-lasting performance in power, water, oil & gas, and industrial automation applications.

This actuator provides smooth, accurate motion control, ensuring stable operation even under harsh environmental conditions. It’s particularly suitable for continuous modulating duty and applications requiring high positioning accuracy.

1. Intelligent Motor Control
   The actuator uses variable-speed motor technology that automatically adjusts torque and speed based on valve load conditions — protecting both valve and actuator from mechanical stress.
2. Part-turn Operation (0°–90°)
   Ideal for quarter-turn valve types, offering fast and repeatable actuation for ball and butterfly valves.
3. Integrated Electronic Controls
   Advanced microprocessor electronics allow local and remote control, diagnostics, and parameter configuration.
4. Communication Compatibility
   Supports digital fieldbus protocols such as Profibus DP, Modbus RTU, and HART, enabling easy integration into DCS and SCADA systems.
5. Robust and Weatherproof Design
   Housing is built for IP68 / NEMA 6P protection with high corrosion resistance, suitable for outdoor and offshore environments.
6. Safety and Reliability
   Features torque and position monitoring, emergency manual override, and fail-safe functions for enhanced plant safety.
