SI UNITS, SYMBOLS AND DIMENSIONING
Flow in tubing and ttings
A simple quick reference sheet to calculate the air ow
in tubes of varying lengths and dimensions.
T
he table below shows the air ow in the different
tube sizes and lengths. The upper value is only the
tubing and lower is the tubing with a straight KQ2H
tting at one end and a KQ2L elbow tting at the other
end.
The ow (Q
n
) is given in l
n
/min. i.e.: IN = 0,6 MPa and
OUT = 0,5 MPa.

Note! If you choose tubing with the same ow as the se-
lected valve, ow is reduced to 71% of valve capacity.
Example: A VZ3000-valve (196 l
n
/min) with 3 meters
of tube, diameter 6 mm/4 mm (191 l
n
/min with ttings),
provides a ow of about 140 l
n
/min.

Example: If two components with the same ow (1) are
serially connected, the ow is reduced to 71% of what a
component normal has.
