Double-seat valves
A special feature of this valve is that the pig can be conveyed through the cylindrical design of the housing. Pigging technology enables valuable products to be recovered at the end of the process step, thereby minimizing product residues in the pipe.

VARIVENT® double-seat valves are used for mixproof shut-off of incompatible products at pipe junctions.
VARIVENT® mixproof valves type C and K are used as an efficient alternative for mixproof separation of incompatible products at pipeline junctions within CIP systems or gas blocks.
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.
Recover the value - Reduce the waste: GEA VARICOVER Product Recovery System
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.
In a shifting political and economic landscape, GEA stays the course. We spoke with Dr. Nadine Sterley, GEA’s Chief Sustainability Officer, about why sustainability remains central to the company’s business strategy, how GEA is progressing on its ambitious goals and what it takes to turn words into action.
