The DE/3M-3 is an analog positioner available in a pneumatic and electro-pneumatic version. The positioner has a heavy duty design making it suitable for use in very harsh conditions. It is used as the control part of the pneumatic valve set in oil and gas, refining, chemical, power, metal production and other fields with automated systems. The pneumatic version accepts a 3-15 psi (0.2-1 bar) signal and the electro-pneumatic version a 4-20 mA signal.

  • When using the electro-pneumatic version an I/P converter is installed on the pneumatic positioner which allows an electric signal to pilot the positioner. It is based on the balanced-forces principle; air distribution to the actuator chambers is executed by an internal spool.
  • The DE/3M-3 is designed to be used for applications on linear actuators with a stroke length of up to 300mm. This positioner is double acting but can also be used as single acting if required.

  • Heavy duty design.
  • High reliability.
  • Split range signal.
  • Feedback system lever/arm free.
  • Standard, offshore, sandstorm, copper free ambient condition.
  • Single and double acting actuators.
  • Low and high ambient temperature.
