Siemens Actuator

Fail-safe actuators drive the valve or damper to a defined position when power or the control signal is lost — essential for heating coils, freeze protection and fire and smoke duties. Non-fail-safe units hold position and suit applications where a controlled stop is acceptable. Match the choice to the valve torque, stroke and the consequence of losing supply.

Fire and smoke rated actuators are built for damper and valve duties in life-safety systems, with defined fail-safe behaviour and ratings suited to smoke-control operation. Confirm the damper or valve torque, the required fail position and the project's fire-rating requirements before ordering, and check compatibility with the existing control panel.

Yes. We source Siemens actuators across all eight sub-types listed and ship worldwide. For sizing, share the valve or damper model, required torque, supply voltage, control signal and fail-safe requirement, and our team will confirm the matching actuator and any replacement for an existing hydronic valve.
