Back-pressure Valves Aseptomag® GD

Aseptomag® single-seat back-pressure valves are used to regulate a pre-defined pressure in UltraClean and Aseptic processing plants.

The desired back-pressure at the valve seat is reached by supplying compressed air to 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 back-pressure valves are available with two or three port connections. The valves are produced with 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.

Actuator
Aseptic back-pressure valves are equipped with an air-closing / air-opening (LL) pneumatic actuator made of stainless steel.

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.

Pressure Control Unit
For the exact setting of the valve closing pressure, the supplied compressed air must be controlled. The use of a pneumatic or electro-pneumatic pressure control unit is recommended.

Feedback units
Aseptic back-pressure valves can be either equipped with open feedback units or T.VIS® control tops by default. Feedback units from third party suppliers can be mounted via special adaptors.

Aseptomag® valve line

Aseptomag® Valve Technology

*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.

Double-chamber Valves Aseptomag® AXV

Aseptomag® double-chamber valves AXV are used for the mixproof shut-off of incompatible products at pipe junctions in aseptic processing plants. Welded stainless steel bellows are used to hermetically seal the product area from outside contamination. The three integrated steam barriers (ISB) can be operated independently from each other and enable the safe separation of both product lines, even when two of the four valve seats are lifted. The integrated function of the single-seat lifting capability permits fully automatic seat cleaning during production. Thanks to the three independent steam barriers, AXV valves enables one side maintenance while production on the other side and offer maximum process and product safety.

Valve Block VESTA® HWA & HXA

VESTA® valve blocks are compact and versatile sterile valves with two independent actuators. The concept of the single-piece housing enables merging, separating or diverting of product flow in tight space conditions. VESTA® valve blocks offer optimized piping by simultaneously reducing dead spaces. The significantly reduced pipe volume and the improved drainability are other characteristic features. In contrast to concepts with individual valves, solutions with VESTA® valve blocks reduce the required quantity of fittings and therefore also contribute to economical installation concepts.

Sampling Valves VESTA® H_A/I

VESTA® sampling valves are used for sampling from product pipelines or vessels in aseptic processing plants. VESTA® sampling valves impress with their modular structure as well as their dead-space-free and compact design. Furthermore, the optimized flow design offers an ideal basis for efficient CIP/SIP processes.

Leakage Valves Aseptomag® ADV

Aseptomag® leakage valves ADV are the simplest form of mixproof shut-off valves. They are used at pipe junctions in aseptic processing plants for uncritical sterile products such as i.e. drinking water. A welded stainless steel bellows is used to hermetically seal the product area from outside contamination. The integrated steam barrier (ISB) enables the safe separation of the product lines with a sterile media and can be safely closed off from atmosphere via the two integrated side valves.
