If there should be any contamination of
the water circuit at a later point in time,
then the valve can be flushed clean at
any time in position 8.

Note
W
To roughly determine the setting with the
given radiator output and system tempe-
rature difference, an average differential
pressure of 80 or 100 mbar is recommen-
ded. For systems with great horizontal
expansion, it is necessary to differentiate
the pressure loss: for example 60 mbar
for valves on the most distance radiators,
80 or 100 mbar in the middle area and
120 mbar for valves on radiators near
the centre. This can only be precisely
determined as part of the pipe system
calculation using a suitable computer
program.
