Shut-off Valves Aseptomag® AF

Aseptomag® single-seat shut-off valves are used for the controlled opening and closing of pipelines in UltraClean and Aseptic processing plants. Thanks to the extended bellows design, the type AF is ideal for applications with high activation frequencies.

Sterylny zawór napełniający przy dnie zbiornika AF — instalacja wewnętrzna

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 and product safety.

Main Components

Housing
The housing is available in bottom-seat execution with either two or three port connections. The valves are produced with standard butt-weld connections by default. Mixed port connection sizes as well as various aseptic pipe connections are available upon request.

Internal Assembly
The internal assembly is available with a shrunk or screwed valve seat seal. In addition to the standard sealing material Tefasep®, other material options such as PTFE and EPDM are also available.

Actuator
The standard version of the pneumatic actuator is designed as spring-closing / air-opening (NC). Furthermore, the actuator can also be executed as air-closing / spring-opening (NO).

Clamp
Due to its solid construction, the 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 filling 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® AXV – valve matrix

Double-chamber valve Aseptomag® DK – valve matrix with T.VIS® control tops

Double-chamber valve Aseptomag® DK – valve matrix

Aseptomag® aseptic valves are designed to meet the highest demands for aseptic processes in the dairy, food and beverage industry.

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.
