Bettis RTS FL Fail-Safe electric actuators are designed to operate appropriate valves when a
fail-safe functionality is required.
Appropriate valves are all kind of valves that require a linear movement to operate
(globe valve, gate valves, etc.).
In the event of a power failure or if the fail-safe function is triggered deliberately, the linear
Actusafe actuator shifts the valve to the fail-safe position, using the built-in energy storage
device to do so.
