Control Valves Aseptomag® RV

Aseptic single-seat control valves are used for the exact setting and control of parameters such as flow, pressure, temperature, or filling level in aseptic processing plants.

Aseptic Control Valve RV

An electro-pneumatic position controller enables the precise positioning of the valve stem by controlling the pneumatic actuator. A welded stainless steel bellow 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.

Main components

Housing
Housings for control valves are available with either two or three 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.

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 (PTFE, EPDM, Viton® etc.) are available. The control cone is available in either an equal-percentage or linear design.

Actuator
The standard version of the pneumatic actuator is designed as spring-closing / air-opening (NC). Alternatively, an air-closing / spring-opening (NO) option is available.

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.

Positioner / Process Controller
Aseptic control valves can be equipped with three different types of positioners. The closed centralized positioner (GRZ) is used by default and can be exchanged with either an open centralized positioner (ORZ) or a closed decentralized system (GRD). Instead of a positioner.

Aseptomag® Valve Technology

Double-chamber valve Aseptomag® AXV – valve matrix

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

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

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.
