  • Epicyclic gear reduction to increment the output torque of the electric actuator
  • Electro-magnetic clutch
  • Low pressure hydraulic control group for manual operation and operating speed regulation
  • Non-intrusive configuration
  • User-friendly push-button panel for operation, setting and diagnostics
  • Bluetooth™ wireless connectivity
  • Advanced maintenance data and alarm reports
  • Valve condition monitoring
  • Configurable ‘data logger’ function for maintenance and diagnostic programs in recorder or event modes
  • User adjustable numeric and graphic displays with 8 language options
  • Double sealed terminal block
  • Digital contactless torque and position sensing
  • Advanced open bus communication protocols:
    • Lonworks
    • Profibus DPV0, DPV1 and redundant DPV1
    • Foundation Fieldbus
    • Modbus
    • Hart
  • Certified for use in SIL 3 applications

General application

The EFS 2000 is available in eight sizes and is designed for on/off or inching operation of valves on safety critical applications in the oil & gas, process and general industry sectors, where conventional pneumatic or hydraulic power supply to fail safe actuators is unavailable.
