Aseptomag® valve line
Shut-off Valves Aseptomag® AVBS
Aseptic shut-off valves are used for the monitored control of fluids at aseptic tank applications. A welded stainless steel bellows is used to hermetically seal the product area from outside contamination. This special design and the durable valve seat seal, made of Tefasep®, enables optimum process security.
Shut-off Valve Aseptomag® AVBS
Main Components
Housing
Housings for bottom-seat valves are available with one or two port connections. The valves are produced with standard butt-weld connections by default. Mixed port connection sizes can be delivered upon request as well as various aseptic pipe connections. Bottom-seat valve housings are available with pipe, welded flange or screwed flange connection to the tank.
Internal Assembly
The internal assembly is available with a shrunk or screwed valve seat seal. In addition to the standard sealing material Tefasep®, other sealing materials such as PTFE, EPDM, Viton®, etc., are also available.
Actuator
The standard version of the pneumatic actuator is designed as spring-closing / air-opening (NC). Other available options include: air-closing / spring-opening (NO), air-closing / air-opening (LL), or with additional seat lifting function (AZ). In addition, the valve is available with a manual actuator (HK).
Clamp
Due to its solid construction, the GEA clamp enables a pressure stable and safe connection of the main components. The special design with three segments allows a service-friendly handling of the component, even under tight space conditions.
Feedback units
Aseptic bottom-seat valves can be either equipped with open feedback units or T.VIS® feedback systems by default. Feedback units from third party suppliers can be mounted via specially designed adaptors.

Aseptomag® Valve Technology
Double-chamber valve Aseptomag® DK – valve matrix
Aseptic bellows valves distinguish themselves with the uncompromisingly hermetic seal of the valve stem, thereby minimizing contamination risks and maximizing detection possibilities. The Aseptomag® valve line is the equivalent for aseptic processes to the hygienic VARIVENT® valve line and provides everything from shut-off and bottom-seat to mixproof and sampling valves. The valves meet the highest hygienic standards required, such as EHEDG and 3-A standards. Thanks to the modular structure, the Aseptomag® valve line also allows tailor-made valve solutions for specific process requirements (higher closing pressures, special materials, special design, etc). Aseptomag® valves can be equipped with T.VIS® control tops and can therewith seamlessly be integrated into an automated process plant.
Aseptic Applications
For aseptic processes, the following areas have to be considered: Product sterilization, conveying and maintaining sterility, and filling under sterile conditions. Aseptic processes signify high-quality products and/or long shelf-life, produced for specific consumer groups. Besides classic UHT milk products, medical nutrition, baby food, aseptically produced beverages and applications within biotech belong to this hygienic class.
