2.2. NEEDLE VALVE AND LEAK/FLOW CALIBRATOR (CDF)

Needle valves are used to calibrate the leakage
limits. These valves have an adjustable leak
and depending on the model allow adjustments
of a few cm

/h to several l/min.
These valves can easily be disturbed and
therefore require frequent use of some means of
checking the setting (e.g. : SAGA 4000).
Note : it is strongly recommended that you do
not leave a needle valve permanently connected
on a leak detection machine with automatic
calibration every "n cycles".
