Electric valve actuator Bettis RTS FQ

quarter-turn90°direct-drive

Product overview
The Bettis RTS FQ is a non-intrusive, quarter-turn fail-safe electric valve actuator designed for reliable ON/OFF and continuous modulation control in safety-critical installations. Its compact mechanical spring-return fail-safe design triggers on loss of power or signal without reliance on batteries or super-capacitors, making it suitable for oil & gas, power, chemical, HVAC, water and wastewater applications.
