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.
Features
1.Intelligent and non-intrusive
2.On/Off (S2) and Continuous modulation (S9)
3.Up to 3687 ft-lbs ( 5000 Nm) Electric Torque
4.Mechanical driven fail-safe operation ( Fail Clockwise or Counter-Clockwise )
5.Direct coupling on the fail-safe with the valve shaft
6.Adjustable speeds
7.Fail-safe trigger selectable in case of drop-off 24 VDC fail-safe signal or main power supply
8.Position resolution .1%
9.SIL3 capable
10.Option De-clutchable handwheel
11.Rotatable in 90 degree steps with remote mounting option
12.Local User Interface with wireless Bluetooth® control capability for configuration, monitoring and diagnostics
