Description
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.
