Cleaning

6.1.

Cleaning recommendation

For the cleaning of SDMS4 valves distiction is made
between two areas.
- Flow areas
The passages of the valve are cleaned by the cleaning liquid
during cleaning of the connected pipelines.
- Leakage chamber
Cleaning of the leakage chamber is undertaken via the
leakage valves. The cleaning liquid is supplied via
one leakage valve and discharged to the atmosphere via the
second leakage valve.
The restraint passage of the cleaning liquid provides for
perfect cleaning of the whole leakage chamber.
Depending on the degree and constituents of soiling, the cleaning
liquids, times and processes must be scheduled for the individual
application.
The compatibility of the individually selected cleaning processes
and liquids with the respectively used seals must be verified.
Under normal conditions, 15 valves DN 25/1" - 100/4"
can be cleaned via one spray distribution line DN 25.
