VARIVENT® Mixproof valve type MX

We are at the beginning of a new era in which successful companies and brands define themselves through their status as pioneers for maximum safety of their products – protecting consumers and their own workforce.

The new GEA VARIVENT® Mixproof valve type MX offers innovative technologies as essential elements of future-oriented safety concepts. It offers a measure of product safety that goes far beyond previous requirements.

Maximum process safety

GEA VARIVENT® Mixproof valve type MX - 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 cleaning efficiency

GEA VARIVENT® Mixproof valve type MX - 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
