Aseptic Valves

Perfect Aseptic Design

The GEMBRA-aseptic valve series stands out due to its uncompromising hygienic design. It is based on process-safe and stable aseptic diaphragm sealing

In order to process microbiologically sensitive products safely and aseptically in process systems, the GEMBRA aseptic valves have been developed. They combine hygienic design and forward-thinking hybrid technology.

GEMBRA stands for high-end stainless steel technology, excellent cleanability and a safe, long-lasting diaphragm seal. The aseptic valves are based on the geometric advantages of our proven seat valve technology. This includes freedom from cavities and optimal idling behaviour.

Germs and impurities don’t stand a chance

The dome-free and gap-free GEMBRA valve concept meets the strict requirements of hygienic design. All seals in contact with the product are made in our proven k-flex sealing material for the highest temperatures and aggressive media.

The sealing system is characterised by a defined load and metallic stop in all components. The process reliability is maintained even at pressure peaks of up to 30 bar.

The GEMBRA valves are available as single-seat valves, changeover valves, tank outlet valves and leak-proof double-seat valves in various nominal diameters.
