AM.3.QF type one way non-compen-
sated throttle valve are fitted with an
O-Ring mounting plate which allows
its assembly for either input or output
regulation. Adjustment is obtained by

knob. They are available in the four
regulating configurations shown in the
hydraulic diagrams.
The standard valve configuration al-
