Butterfly valves
GEA Hygienic Leakage Butterfly Valves offers an interesting valve variant for the mixproof separation of media. Highly functional, CIP/SIP-enabled and easy to service, this valve supplies continuous safety to production processes.
Mixproof separation of the two product areas, when the valve disk is closed, is achieved through two peripheral sealing edges with the leakage cavity between them.
The leakage cavity itself drains automatically and is designed in such a way that it can be flushed, from one drain port to the other, without dead areas or short-cuts. With little resources applied, products are successfully and completely flushed out, for optimum cleanability.
For narrow mounting situations and low air consumption the pneumatic actuators have been made even more compact.
The gap-free design ensures optimum cleanability and fulfils highest demands to hygiene.
Torque maxima towards both end positions enable application on both normally closed and normally open valves. Metallic stops ensure exact disk positioning. There are air-to-spring and air-to-air variants.
The integrated T.VIS® interface also safely accommodates optional accessories – booster cylinder, two-position stop and limit stop. The internal pneumatic system reduces the risk of failures, being without external tubing.
All actuators are by default applicable for Ex zones. Compliance of any electric accessories with Ex regulations must be ensured.
The GEA Hygienic Butterfly Valves provide a complete range of variants to serve any application. They are used as cost-effective shut-off elements on valve blocks, panels and pipe fences for product and cleaning.
The DISK LOCK is available for all nominal size of GEA hygienic butterfly valves and GEA hygienic leakage butterfly valves to protect your workforce and maintenance operations.
Resource-efficient fashion has been a long-sought ambition amid the fashion industry’s considerable contributions to global carbon emissions. The need to close the loop by recycling textile fibers into virgin-like materials is higher than ever but seemed like a distant dream until now: Circ, GEA’s American customer and pioneer in the field of textile recycling, might be rewriting the future of the fashion industry.
Alternative proteins are promising – yet still expensive to produce. The usual response is that scaling up will solve this issue. But what if the solution was really about getting better, not just bigger? From more efficient, high-yield processes to upcycling waste heat, engineers are reshaping how we grow food.
As anti-cancer drugs become more powerful and complex, GEA is redefining how to safely freeze-dry these life-saving treatments.
