Kieselmann 5844 S-S-S GEMBRA Aseptic Changeover

Details

Germs and impurities don’t stand a chance

Unbeatably aseptic! We have replaced the bellow seal with a diaphragm seal!

In order to process microbiologically sensitive products safely and aseptically in process systems, we have developed the GEMBRA aseptic valves. 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.

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.

• Level inner surface/excellent cleanability

• Safe leakage detection

• Shockproof up to 30 bar

• Simple, cost-effective seal replacement

• Metallic diaphragm support

• Anti-adhesive k-flex/PTFE (FDA compliant) sealing material
