The key to the latest advance in the GEA VARIVENT® concept are technical developments in crucial details that make it possible to prevent incompatible media from mixing under all conceivable conditions and thus to meet the highest safety requirements.

Maximum Process Safety
The optimized physical design of the leakage cavity creates a negative pressure. Should a seal fail, the product is removed by vacuum and guided to the periphery without the risk of contamination (Venturi effect).

Maximum pressure relief
Thanks to specially shaped balancers in both pipelines, the valve remains stable in the closed position even in the event of water hammer and, on the other hand, retains its full ability to act even in the case of hydraulic lock or thermal expansion of the medium.

Maximum valve monitoring
Up to four feedbacks can be applied to ensure exact control and documentation of the valve status at all times.

Maximum cleanability
The uncompromising hygienic design of all components ensures maximum efficiency in valve cleaning, now enhanced by automatic external cleaning of the lower balancer when the lower valve seat is lifted.

Maximum compliance
The specially improved valve technology of the new GEA VARIVENT® Mixproof valve type MX fulfills the world's strictest design specifications for hygienic valves (3A, EHEDG).
