An Extremely Accurate and Precise Valve Positioner

The EL electropneumatic positioner combines the precision and adaptability of a digital electronic control circuit with the smoothness and efficiency of Kinetrol's proven proportional servo valve, to give the best available 4-20mA positioning performance from rotary pneumatic actuators. 

This unbeatable performance is combined with the easiest available setup procedure, easiest access to all functions and options, easy connectibility, and a truly compact all-metal enclosure, plus unique easy-set isolated angle retransmit and limit switch options inside the same enclosure.

Features
  • Fast, smooth and precise control from a digital circuit and proportional servo valve 
  • Simple time saving field set up
  • Quick calibration via push buttons and LED feedback and easy reversal of rotation sense (clockwise/counter clockwise) without special tools or parts change. 
  • Universal application
  • The unit can be mounted in any orientation on to any quarter turn or linear application by connection via a NAMUR or Kinetrol square interface. 
  • Loop powered
  • No separate power needed, just a 4-20mA signal plus air supply. 
  • Integral options - easily retrofitted modules include:
    • Two wire 4-20mA isolated angle retransmit 
    • Mechanical or inductive position indicator switches (general or hazardous areas) 
    • Clear Cone high visibility indicator 
    • Threaded conduit entries or DIN plugs for external connection.
  • Intrinsically safe approved options 
  • Weatherproof, compact and robust metal housing 
  • Zero backlash coupling with easily adjustable switch strikers 
  • Vibration and shock resistant to 4G 
  • Built in gauge ports/external connections
