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.
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).
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.
Up to four feedbacks can be applied to ensure exact control and documentation of the valve status at all times.
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.
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).
Closed actuator housings, thoroughly protected by specially designed piston seals - designed to be maintenance-free. The robust design supports uninterrupted process operation and saves valuable time and operating costs.

VARIVENT® 24/7 PMO
The 24 / 7 PMO Valve® 2.0 is standardized and tailor-made for use in PMO-regulated systems. 24 / 7 PMO Valve® is a registered trade mark of GEA. It describes double-seat valves that have been authorised for use in PMO-regulated systems, where seat lifting occurs to clean the leakage chamber while the other pipeline is carrying product. This grants system operators the possibility of cleaning all valve parts in contact with the product simultaneously with the production process. In this way, the valves permit uninterrupted production on a 24/7 basis. -
