Frequently asked questions
Common questions about Siemens Actuator from 3G Electric.
How do I select a Siemens actuator for a globe or ball valve?
Match actuator torque or close-off rating to the valve's required shut-off pressure and differential, confirm the stroke and mounting interface suit the valve body, then choose the control signal — 0-10 V, 4-20 mA or floating — and whether spring return is needed for fail-safe positioning.
What is the difference between fail-safe and non-fail-safe Siemens actuators?
Fail-safe actuators carry a spring that drives the valve or damper to a defined position when power or the control signal is lost, protecting coils, ducts or processes. Non-fail-safe units hold their last position and are used where loss of signal is not a safety concern.
Do you supply fire and smoke rated Siemens actuators worldwide?
Yes. We supply fire and smoke rated actuators for life-safety damper and valve applications, alongside pneumatic, zone valve and replacement hydronic mechanical actuators. Share the application, voltage and required position on signal loss and we will confirm a suitable unit and lead time.
