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
