AM.7.QF type one way non-
compensated throttle valve are fitted
with an O-Ring mounting plate which
allows its assembly for either input or
output regulation. Adjustment is
obtained by means of a grub screw.
They are available in the three
regulating configurations shown in the
hydraulic diagrams.
All configurations have a built in check
valve that allows reserve free flow.
