GEA Tuchenhagen 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.

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


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.


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.


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.

Technical Data

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