Intelligent linear electric actuators ELS (2,3 kN to 25 kN)

The ADCATrol ELS series intelligent linear electric actuators are designed for operation of control valves in modulating and on/off services in process engineering and industrial applications. The actuator is equipment as standard with positioner and active feedback function, automatic commissioning as well as comprehensive diagnostic functions. 

The ELS is optionally available with super capacitors for fail-safe operation, returning to its respective fail-safe position in case of power failure/interruption. 

  • Modular retrofittable design. 
  • Automatic comissioning with the press of one button. 
  • 115 V AC, 230 V AC 50/60 Hz and 24 V AC/DC supply voltages. 
  • Manual operation with handwheel. 
  • IP 65 protection (IP 67 on request). 
  • Mounting to valves made via yoke or mounting flange DIN 3358, enabling easy connection to all types of valves. Standard version is suitable for ADCATrol valves. 
  • Sturdy metal main frame for mainboard and accessories. 
  • Mechanical stroke indication via anti-rotation bar. 
  • Friction clutch for easy and tool-free adaptation to the valve stroke. 
  • Universally usable actuators due to control via 3-point-step controllers and analog input signals (0(2) to 10 V, 0(4) to 20 mA). 
  • Additional limit switches. 
  • Electric fail-safe with super capacitors. 
  • Local control to enable manual operation through the use of buttons and on site diagnosis without needing a PC. 
  • Profibus DP and Modbus RTU communication. 
  • Heating resistor. 
  • IP 67 metal cover. 
  • Silicone free version.
