Bettis RTS FQ Fail-Safe Quarter-turn Electric Valve Actuator
A non-intrusive intelligent fail-safe quarter-turn actuator for ON/OFF and modulation control in fail-safe applications. The robust and compact mechanical spring return design can be triggered to fail-safe action either on loss of power or signal. With no dependency on super-capacitor or battery-backup, this state of the art design is widely used on valves for oil & gas, power, chemical, HVAC, and water and wastewater industries.
