2 Safety
2.1 Intended use
Aseptic leakage valves are mix-proof switch elements for aseptic process
systems and permit the safe separation of incompatible media. The media
separation is done via the integrated sterile chamber (ISB), which is separated
hermetically from the atmosphere with a seal each to both product lines and via
two side valves (inlet and outlet). Any leakage at the sealing elements is diverted
through the side valves.
For safe operation, it is mandatory that the following points are observed in the
different process steps:
Transfer
During a media transfer through the main valve both side valves must be closed
completely.

Cleaning sterile chamber
After a media transfer the sterile chamber must be flushed at least with one
sterile medium. After the main valve has been closed, both side valves can be
put in the open position and thus permit the flushing of the sterile chamber.
