BELIMO Actuator Valve

Match actuator torque to the valve body's close-off pressure rating, then confirm the control signal (on/off, floating or 0-10 V modulating), supply voltage and stroke time. Check the differential pressure at the valve, not just line pressure, and allow margin for aged or dirty systems before ordering.

Fail-safe actuators use a spring return to drive the valve to a defined position when power is lost, which suits heating coils, freeze protection and smoke control. Non-fail-safe actuators hold their last position and are typically used on cooling or modulating duties where a power interruption is not safety critical.

Yes. We stock fire and smoke rated actuator lines alongside ball, zone and spring return models, and ship worldwide. Confirm the required listing, temperature rating and damper or valve interface when enquiring, and we will match the correct actuator to your assembly.
