8793 Process controller

Digital electropneumatic process controller

  • Compact and robust design
  • Easy Start-up using tune function of the positioned and process controller
  • Integrated diagnostic functions for valve monitoring
  • Dynamic positioning system with no air consumption in controlled state
  • Optimized for high-pressure proportional valves MPG and HPG
  • Version for quarter-turn actuators (NAMUR) available

The robust and compact Bürkert process controller has been tailored for m-tech proportional valves with a remote stroke sensor. The process controller is equipped with additional diagnostic functions to monitor the state of the valve. Operation is done via the external operation and display module with a backlit graphical display.
