Aseptomag® valve line 控制阀 Aseptomag® RV

Aseptomag® 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.

An electro-pneumatic positioner enables the exact setting of the valve stem by controlling the pneumatic actuator. 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
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 as well as various aseptic pipe connections are available upon request.
 
Internal Assembly
The internal assembly is available with or without 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. The control cone is designed as equal-percentage by default.
 
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 are usually equipped with a closed centralized positioner (GRZ) mounted directly on top of the valve by a specifically designed adaptor. Depending on process requirements, it is also possible to apply a process controller instead. Other control options are available upon request.

Aseptomag® Valve Technology

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.
