Numatics' 608 & 609 Series SentronicD is a digitally operated pressure regulator valve.

SentronicD stands for:

  • Digital control
  • Display (integrated)
  • Direct operated valve

With the Data Acquisition Software (DaS) and the RS232 interface, it's now possible to optimally adjust the valve's control parameters to a specific application. The scope function allows you to log and read the system's response in real time.

The DaS capabilities streamline the development process and identify application-specific problems at an early stage. Saved parameters can also be used for future production so that valves are factory-set to a specific application.


  • SentronicD is a highly dynamic 3-way proportional valve with digital control
  • A special feature of the SentronicD is its DaS software supplied for optimum adjustment via PC and viewing of command and feedback signals
  • Other functions are valve diagnostics, parameter setting, and maintenance
  • SentronicD can be configured for dual loop control of process variables such as flow, force, speed, RPM, and temperature


  • Minimum hysteresis
  • Quick response times
  • Very high sensitivity
  • Standard 50 μm filtration
  • No constant air consumption
  • Analog feedback output
  • Easy change of control parameters
  • Digital control
  • Integrated display (optionally without)
  • PC communication
