Testing device for proportional valves

Checker Valve Expert Vers. 2.3

Universal tester for proportional valves with integrated electronics

The crime scene: proportional valve. And you are called upon to investigate. Because the darling device is obviously malfunctioning or simply refuses to be taken into operation. And there they are again, these constantly emerging questions:

  • Is the voltage ok?
  • Is the desired value set correctly at the valve, and does it correspond with the actual value?
  • How can I check the functionality very easily before the installation?

Good that you have our universal tester for proportional valves to hand! We developed it in cooperation with Dietz Automation GmbH, mainly for service calls and start-up procedures.  It can be used to easily drive and check the function of proportional valves with integrated electronics and an operating voltage of ±15 V or +24 V. A major advantage is the integrated switch for operating an additional release valve (24V/DC, max. 3A).

The complete tester comes in a case, incl. connection cable (length 3 m) and a 230V-50Hz power pack for the demanding everyday routines.

The details:

  • Extremely robust aluminium casing with sturdy handles
  • LEDs show the selected signal type for set and actual values, the supply voltage and release
  • Large and legible digital display for set values and actual values
  • Indication of the external supply voltage at the valve
  • Additional switch output for a 24V switching valve (e.g. release valve)
  • Potentiometer for infinitely variable adjustment of set values
  • Control operation for checking the signals arriving at the valve while the higher-level control is active
  • Control operation by way of the included power pack, independently of the higher-level control
