NOTE:
Also refer to the operating manual for Bettis RTS CM Compact Multi-Turn Series.
Bettis RTS FQ Fail-Safe Quarter-Turn electric actuators are designed to operate appropriate
fittings when a fail-safe functionality is required.
Appropriate fittings are all kinds of fittings that require a 90
(butterfly valves, ball valves, taps in general, etc.).
In the event of a power failure or if the fail-safe function is triggered deliberately, the
actuator shifts the fitting to the fail-safe position, using the built-in energy storage device
to do so.
