Siemens Actuator

Match the actuator's torque (for dampers) or force (for valves) to the requirement at your operating pressure drop. Check the valve or damper manufacturer's data for minimum torque/force, then select a Siemens actuator that exceeds it by at least 30% for reliable operation.

Fail-safe actuators use a spring return to move the valve or damper to a safe position (open or closed) when power is lost, protecting processes and equipment. Non-fail-safe actuators hold position on power loss. Choose fail-safe for critical applications like burner or safety shutoff.

Yes, 3G Electric stocks Siemens fire and smoke rated actuators and ships worldwide. These models meet stringent safety standards for use in smoke management systems. Confirm your required certification (e.g., UL, EN) and voltage before ordering to ensure compliance.
