Aseptic Filling Valves Aseptic Filling Valve AF

Aseptic filling valves are used for the monitored opening and closing of pipelines in aseptic processing plants.

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. Due to their extended bellow design, aseptic filling valves are ideal for plants with high valve stroke frequencies, such as bottling plants.

Main components

Housing
The housing is available as a bottom-seat variant 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.

Actuator
The standard version of the pneumatic actuator is designed as spring-closing / air-opening (NC). Other designs are air-closing / spring-opening (NO) and air-closing / air-opening (LL).

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 filling valves 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.
