Features & Benefits

  • 3-button interface and LCD for easy calibration and information display.
  • Easy configuration of split range and reverse acting operation.
  • Easy access to wiring terminal.
  • Non-contact valve position measurement via Hall Effect sensor. Eliminates the need for drive arms, linkages and increases overall resolution, accuracy and reliability.
  • Advanced auto-calibration.
  • Valve speed adjustable via microprocessor control.
  • Available with optional dry contact limit switches.
  • Optional 4-20 mA position feedback transmitter – HART version only.
  • High-flow spool valve option for larger actuator/valves. Eliminates the need for volume boosters in some applications.
  • Highly visible position indicator for rotary applications.
  • Easily accommodates large stroke valves, such as knife gates.
  • Fully compatible with AMS™ software and DTM.
  • Engineered resin enclosure is robust yet lightweight with exceptional chemical, UV and impact resistance.
  • Easy access to wiring terminal connectors.
