Performance Characteristics
Shifting Action
Spring centered and spring
offset models must be
piloted continuously to
maintain the shifted position.
Detent no-spring models may
be energized momentarily
(approximately 0.1 second).
Spring centered models
return valve spool to center
position when solenoids are
de-energized.
Spring offset models return
spool to offset position
by pilot pressure when
solenoids are de-energized.
CAUTION: Spring
offset models
contain no offset
springs in the main stage and
are hydraulically offset via
spring offset pilots. When
pilot pressure falls below the
minimum shift pressure, the
main stage spool is free to
oat.
When detented models
are de-energized, the pilot
and main spools remain in
the last position attained,
provided there is no shock,
vibration, unusual pressure
transients and the spool axis
is horizontal.
If pilot pressure fails or
falls below the minimum,
the main spool will spring
center (at spring centered
ow rates) and cannot drift
to reversal of ow (pilot
stage remains in detented
position).
CAUTION: Flow
conditions of the
spring centered
position must be selected
with care, both for the effect
on the direction of the ow,
and the pilot pressure.
(The “9” main spool will
not ensure sufcient pilot
pressure in the center
position.)
CAUTION: Surges
of oil in a common
tank line serving
these and other valves can
be sufcient enough to cause
inadvertent shifting of these
valves. This is very critical in
the no–spring detented type
valves. Separate tank lines
or a vented manifold with a
continuous downward path
to tank is necessary.
Note: Any sliding spool valve,
if held for long periods of time,
may stick and not spring return
due to uid residue formation
and therefore, should be cycled
periodically to prevent this from
happening.
When used as other than a
normal 4–way valve, consult
your Eaton representative.
