GEA Tuchenhagen Cross Valve AXV

Aseptic double chamber valves type AXV are flow control devices for 24/7 aseptic processing plants.

The three integrated steam barriers (ISB) 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. The valve build-up is similar to a standard double chamber valve and therefore also provides easy maintenance and low Total Cost of Ownership. The valve enables the total separation of antagonistic media and offers you maximum process safety.

Main Components


Housings for double chamber valves type AXV are available with two, three or four 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 Assemblies 

The double chamber valve type AXV includes two identical internal assemblies with two valve seats each. The upper seats (seats B) of the internal assemblies contain a shrunk valve seat seal made of Tefasep® (optionally PTFE). The lower valve seats are available with a shrunk or screwed valve seat seal. In addition to the standard Tefasep® sealing, other sealing materials such as PTFE, EPDM, Viton®, etc. are also available for the lower seat. The nominal diameter of the valve is determined by the two larger valve seat.



The double chamber valve type AXV also includes two identical actuators. The standard version of the pneumatic actuators is designed as spring-closing / air-opening (NC) and includes single seat lifting for both valve seats (seats A+B) as well as a full valve stroke (3 valve strokes in total).



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.


Side valves 

The sterile chamber includes a steam inlet and a drain valve by default. Both valves can be either equipped with normally closed (NC) or normally open actuators (NO), depending on customer specifications. Furthermore, the drain valve is available with an integrated temperature probe which enables temperature measuring in the sterile chamber. The double chamber valve AXV includes three sterile chambers and therefore also three steam inlet and three drain valves.


Feedback units 

Aseptic double chamber valves type AXV 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.


Technical Data


Higher closing pressures, other materials, higher surface qualities and higher operating temperatures are available upon request.
