Valve technologies

The following chapter shows the various
valve technologies based on exemplary
10.1.1
A-/B flushing technology
In A/B flushing technology, several riser
branches or distribution lines are connec-
ted to a common flushing line. Here, one
A valve and the B valve are successively
opened and closed together.
This guarantees that there is no idling in
the flushing lines and there is no water
exchange between the pipelines to be
flushed.
Example of a flushing process:
A1 and B1 open in accordance with the
specifications, A1 and B1 close
A2 and B1 open in accordance with the
specifications, A2 and B1 close
A3 and B1 open in accordance with the
specifications, A3 and B1 close
A4 and B1 open in accordance with the
specifications, A4 and B1 close
If valve A1 is flushing, the
pending flushing processes
of other valves are blocked.
With temperature flushing,
these are then carried out
successively by the system.
