Control Device: Control D

The stand-alone control device CONTROLD is used for open-loop, closed-loop or double-loop (cascaded) process control. It is designed to control proportional valves by regulating the current in the valve‘s solenoid coil. The maximum value of the solenoid coil’s current is automatically determined with the autotune function.

Higher precision requirements can be met by controlling flow, temperature, pressure, force etc. using additional analog feedback inputs.

  • Easy change of control parameters
  • Digital control
  • Integrated display
  • AUTO-ADAPT button for automatic adaptation
  • Suitable for use with series 602 proportional valves

Analog I/O Module for Valve Islands for proportional valve control

This I/O module expands the functional range of valve islands equipped with G3 electronics. It allows the user to control analog proportional valves via the G3 electronics and a fieldbus and to benefit from the resulting advantages:
  • Elimination of analog output cards on the PLC
  • Reduced cabling
  • Diagnostics via fieldbus

I/O Analog module  


Adjustable Pressure Switch


  • With or without protection and status indicators 
  • G 1/4 or subbase mounted body

The adjustable pressure switch is suitable for use with pressure control valves only.
