EFX-D Series
30-3000 N·m · Multi-turn
EFX-D multi-turn intelligent electric actuator for gate, globe, sluice, and linear valves needing torque range, feedback, and robust controls.
FFC EFX actuator packages support thermal, renewable, and utility valves needing reliable isolation, modulation, and plant controls.
The duty
Power and energy plants automate valves in boiler feed water, cooling water, condenser isolation, steam admission, fuel handling, and emissions control trains. Renewable and hydrogen projects add new duties around electrolyzers, compression, and storage.
Duties span open/close isolation of large bore lines, modulating control of attemperators and bypass valves, and rapid ESD chains tied to plant protection systems. Position feedback is often integrated through Profibus, Modbus, or hardwired 4-20 mA signals.
Hot zones near boilers and turbines need thermal isolation between valve and actuator. Outdoor switchyards and renewable sites demand sealed enclosures with humidity protection, while heavy industry hazardous areas need explosion-proof variants.
FFC EFX-D suits the larger multi-turn duties on gate and globe valves, EFX-Q covers butterfly and ball valves on cooling water and gas distribution. Torque, IP class, and certification details vary by valve and project — share the line list and FFC will confirm the actuator selection.
