Aseptic valves

Germs and impurities don’t stand a chance

In order to process microbiologically sensitive products safely and aseptically in process systems, we have developed a series of aseptic valves. They combine hygienic design and forward-thinking hybrid technology.

Our aseptic valves stand for high-end stainless steel technology and excellent cleanability. 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 aseptic 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.

Our aseptic 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

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