7.3. The leakage chamber (fig. 7.3.)
The cleaning of the leakage chamber is undertaken by CIP
spraying. CIP cleaning connection (C).
The valve shafts being lifted, the CIP liquid also cleans the

leakage chamber.

The spraying does not produce pressure build-up in the leakage
chamber and can be carried out in closed and in open valve
position. The conduct of the cleaning liquid provides for a
biologically perfect cleaning of the whole leakage chamber.
Under standard conditions 15 valves DN 40 - 100 / 1,5" - 4"
can be cleaned via one spray distribution line DN 25.

The lifting cycles refer to a cleaning pressure of p = 2 - 5 bar.
Depending on the degree and constituents of soiling, cleaning
liquids, cycles and processes must be adjusted for the individual
application.
The comptability of the individual cleaning processes and liquids
CIP
with the respective seal materials must be verified.
