Inside valve VIS/VAP

Syntegon aroma protection valves are based on patented and proven venting technology to protect product aroma and to maintain the quality of degassing products, sensitive to oxygen. They protect against excess pressure in airtight packaging and eliminate the intermediate storage of degassing products.

The interior VIS/VAP valve is sealed at the inside the packaging material and has an extremely slight and reproducible opening and closing pressure.

  • Application Examples

    Application:

    Optimum aroma and quality protection for degassing products and oxygen-sensitive products, such as

    • Coffee
    • Fresh dough
    • Pet food
    • Cheese
    • Fresh grass

    Operating principle

    The valve consists of a base body and a membrane with valve fluid between it. A filter fleece protects the valve from contamination of small particles. Even a very slight increase of pressure inside the package causes the membrane to bulge.

    Given increasing overpressure, the membrane is raised higher at one part of the valve until it forms a channel in the fluid, through which the gases can seep to the outside.
