Ports M5 [10-32 UNF],
1/8”, 1/4” NPTF
The undirectional flow controllers are
equipped with M5 [10-32 UNF], 1/8” and
1/4” ports, each of which is available with
two different types of adjustment (see dia-
grams).
They are used mainly for controlling
the speed of cylinders.
They may be mounted on control panels
or cylinders, as required.
*Qn flowrate [SCFM] determined with a supply pressure of 6 bar, [87 psi], and with a pressure drop of 1 bar, [14.5
psi].
