How does this valve work?

The valve consists of a valve body and a membrane. Even a very slight overpressure in the package causes the membrane to bulge.

As the overpressure is increasing, the membrane rises at one valve location until a channel is formed, through which the gases can escape to the outside.

After the gas has been successfully vented and the pressure compensated, the valve closes and the membrane lies once again against the valve body. The content is thus reliably protected against external oxidation.

Valve uses:

  • removes excessive gases inside the pouch

  • protects from oxygenation

  • preserves flavour and fragrance for longer
