Product overview
Industrial electric actuator platform
The EFX-Q series brings FFC intelligent actuator control to compact quarter-turn duties with configurable stroke, torque, protection, and communication options.
Class F insulation
Class F insulation supports reliable operation in demanding actuator duty cycles.
Double-sealed wiring cavity
Separated wiring and control cavities reduce moisture ingress during commissioning and service.
Hardened copper alloy worm gear
Wear-resistant worm gearing supports high torque transfer and long service life.
Adjustable stroke, time, and torque
Configurable travel, operating time, and torque settings simplify valve matching.
Low-noise operation
Mechanical and motor design keeps operating noise under 70 dB @ 1 m.
Fieldbus support
4-20 mA, MODBUS RTU, and PROFIBUS DP options integrate with modern control systems.
ESD/open/close/stop
Emergency shutdown and discrete open, close, and stop commands support plant safety logic.
