Germsand impurities don’t stand a chance
Unbeatablyaseptic! We have replaced the bellow seal with a diaphragm seal!
In orderto process microbiologically sensitive products safely and aseptically inprocess systems, we have developed the GEMBRA aseptic valves. They combinehygienic design and forward-thinking hybridtechnology.
GEMBRAstands for high-end stainless steel technology, excellent cleanability and asafe, long-lasting diaphragm seal.The aseptic valves are based on the geometric advantages of our proven seatvalve technology. This includes freedom from cavities and optimal idlingbehaviour.
Thedome-free and gap-free GEMBRA valve concept meets the strict requirements of hygienic design. All seals in contactwith the product are made in our proven k-flexsealing material for the highest temperatures and aggressive media. The sealingsystem is characterised by a defined load and metallic stop in all components.The process reliability ismaintained even at pressure peaks of up to 30 bar.
TheGEMBRA valves are available as single-seat valves, changeover valves, tankoutlet 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
