Next level safety
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 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.

24 / 7 PMO Valve® 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.
LoTo solutions available for all hygienic seat valves ensure a safe maintenance & commissioning of process plants. Use an easy-to-apply AIR LOCK to cut off the control air connection. Or replace the feedback system with a sturdy DISK LOCK to safely block valve action.

What if your favorite chocolate didn’t require cocoa beans and your coffee was locally produced? As climate disruption, price hikes and ethical concerns hit two of our most beloved indulgences, scientists are reimagining how we produce them – using microbes, not monocultures. The goal: preserve the flavor and properties of coffee and chocolate while minimizing carbon emissions and improving food resilience.
Ports now compete not just on logistics, but on sustainability. At Greece’s Piraeus port, an advanced processing and recovery facility recycles ship waste oil into fuel. Equipped with GEA’s high-performance centrifuges, it sets a new benchmark for state-of-the-art, environmentally responsible port operations.
The 2022 CO2 shortage forced breweries to review their dependency on global supply chains. Many were forced to close, unable to carbonate their products. At its breweries in Germany, OeTTINGER GETRÄNKE is turning its own CO2 into a powerful lever for independence and sustainability – with the help of CO2 recovery technology from GEA.
