GEA Tuchenhagen Back-pressure Valves Aseptomag® GD

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

The desired product pressure is reached by supplying compressed air to 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. Back-pressure valves are commonly used in pasteurization and sterilization plants.

Main Components

Housing  

Housings for back-pressure valves are available with 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 or without a shrunk or screwed valve seat seal. In addition to the standard sealing material Tefasep®, other material options (PTFE, EPDM, Viton® etc.) are available.

Actuator

Aseptic back-pressures valves are equipped with an air-closing / air-opening (LL) pneumatic actuator.

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 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 specially designed adaptors.
