Installation & Initial Operation
Setting the flow volume
The fitting has two measuring
ports for connecting it to a dif-
ferential pressure meter. As
such it is possible to set the valve
to a specified flow volume value.
The measuring computer (e.g.
"OV-DMC 2") measures the pre-
vailing differential pressure be-
fore (+) and after (-) the measur-
ing orifice integrated in the valve,
thereby calculating the current
volume flow. This makes it pos-
sible to balance between target
and actual values. Any devia-
tions can be readjusted using the
handwheel.
When using a measuring com-
puter, insert
needles into the two open-
ings of the measuring ports.
Connect the measuring tube
marked in blue to the valve
labeled with "-" and the tube
marked in red to the "+" valve,
accordingly.
Should you use a
differential pressure
meter, please also note
the relevant
instructions for use.
