Realistic test conditions for our products from the hygienic sector

The requirements placed on the service life, reliability and functionality of applied valves inprocess technology – especially in the pharmaceutical and food industries – are increasing all the time. To meet these requirements in the long term, we have invested in a modern multi-medium testing facility.

Multi Testing Area

Process simulations for cleaning and sterilisation processes with the new multi-medium testing facility

With our new multi-medium testing facility, we are able to test our valves up to orifice sizes of DN 100 under realistic conditions. This enables us to simulate cleaning and sterilisation processes and to analyse the behaviour of our products in extreme and borderline areas.

These resistance and long-term tests help us to optimise the service life and reliability of all components that are in direct contact with the medium.

How do these tests work?

The test conditions are defined prior to testing. For example, temperatures, pressure ranges, number of cycles and switching times of the valves are defined for various media. Testing is then performed automatically. The test parameters can be recorded and documented to verify the test procedure.

Which media are used?

  • Purified and ozonised water
  • Acids
  • Lye
  • Pure steam
  • Compressed air
  • Vacuum
  • Further application-specific media

Flexible media sequence thanks to various test chambers

The six test chambers enable us to determine the media sequence according to the respective requirements. This allows testing to be carried out as close to real application conditions as possible.

Do the test procedures comply with generally applicable standards?

The test procedures are based on relevant standards and regulations, such as the international standard for biopharmaceutical manufacturing equipment ASME BPE Appendix K. Application-specific test procedures are also possible.

Do not leave anything to chance. This is especially true when choosing your process components to ensure sterile and contamination-free end products. You should therefore check out our tried and tested valves:
