Pilot Choke Adjustment(s)
Pilot choke is adjusted by backing off
locknuts and turning adjusting screws
inward (clockwise) to decrease rate of
spool travel and outward
(counterclockwise) to increase the rate.
Pilot oil for models with this feature
should be taken from a source having a
constant pressure. See spool control
modifications in model code.
Stroke Adjustment(s)
Stroke adjustment limits movement of
the main stage spool. Backing off the
jam nut and turning the adjusting screw
inward (clockwise) decreases spool
stroke. See spool control modifications
Spring offset model has internal spring
which offsets the spool when pilot
connection “X” is open to tank. Pilot
connection “Y” becomes a drain
connection, which must be connected
directly and independently to tank at
centering time by using pilot pressure to
center the spool. The centering springs
are used in addition to pilot pressure to
insure positive centering of the spool. The
valve spool is returned to center position
by pilot pressure and centering springs. If
pilot pressure fails or falls below the
required minimum, the spool will return to
center position at minimum pilot pressure
flow rates for pressure centered valves.
