Description

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

 

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.
