  • VSTC1
  • VSTC2
  • VSTC3

Product information

With this unique product it is very easy to test a valve system. It can be used for the following systems:

  • Modulating and on/off systems
  • Hydraulic and pneumatic
  • Rotary and linear
  • Double acting and spring return

Because of the compact and mobile design the VSTC can be used in the workshop or on inspections in the field.
The VSTC makes automatic tests of the valve system and stores all valve system data on a pc, with the software included in the kit. With these data it is easy to generate reports showing information and graphs of the valve system performance.



The Valve System Test Centre software is designed to automate the test and give an easy overview of the testresult.

The following tests can be performed:

  • Stroke test
  • System test
  • Step test
  • Life cycle test
  • Deadband test
  • Pressure test
  • Pressure switch test
  • Flushing sequence

Licence and updates

1 licences is delivered with every VSTC unit. Licence includes the following:

  • Support by phone and e-mail for 1 year
  • Free upgrade 1 year

It is possible to expand the support and upgrade.
