General description
DG*V-7 valves are used
primarily for controlling
the starting, stopping and
direction of uid ow.
Two series of valves,
DG5V solenoid controlled,
pilot operated and DG3V
pilot operated models
are available with a wide
selection of spools. These
include meter-in and meter-
out spools and a regeneration
type that can obviate extra
valves essential in traditional
circuit arrangements.
All spools have been
designed to provide good
low shock, fast response
characteristics which can
be enhanced by optional
stroke and/or pilot choke
adjustments.
Models include spring offset,
spring centered and detented
versions.
Features and Benets
• High pressure and ow
capability for maximum
cost-effectiveness.
• Low headloss to minimize
power wastage.
• Low shock characteristics
to maximize machine life.
• Facility to change solenoid
coils without disturbing the
hydraulic envelope.
• The many optional
features, particularly for
DG5V valves, permit
matching to virtually every
application within the
valve’s power capacity.
• Optional mainstage
spool position
monitoring switch

Application Notes
Model Code (Cont...)
Pilot Pressure
a. Pilot pressure must
always exceed tank
line pressure by at least
the requisite minimum
pilot pressure. This also
applies when combining
open center spools (0, 1,
8, 9 and 11) with internal
pilot pressure, but they
should be used only with
externally drained valves.
b. Internally drained valves
may be used only when
surges in the tank
line cannot possibly
overcome the minimum
pilot pressure differential
referred to above.
When the possibility of
pressure surges in the
tank line exist, externally
drained valves are
recommended.
c. When DG5V-7-*N valves
are de-energized the pilot
and main spools remain
in the last selected
position, provided
that pilot pressure is
maintained. If pilot
pressure fails, or falls
below the minimum, the
main spool will spring
center.
Caution: Because of this in-built feature
the ow conditions of the center position
must be selected with care, for the effect
on both the direction of ow and the pilot
pressure.
Stroke Adjustment Options
These control the maximum
opening of the main spool/
body passages by adjusting
the limits of spool stroke. By
this means, the response
time and the pressure drop
across the valve for any
particular ow rate can be
controlled. Stroke adjusters
can be tted at either or both
ends of the main-stage valve
for adjusting the stroke in
one or both directions. One
use of stroke adjusters is
for controlling the metering
characteristics of “X*” or
“Y*”- type spools. (See
model code #4.)
Pilot Choke Adjustment
Options
These provide a meter-out
ow control system to the
uid in the pilot chambers
of main-stage valves. It
allows the velocity of the
mainstage spool to be
controlled, thereby reducing
transient shock condition. For
optimum results, a constant
reduced pilot pressure is
recommended.
Control Data, General
a. Dependent on the
application and the
system ltration, any
sliding spool valve,
if held shifted under
pressure for long periods
of time, may stick and
not move readily due to
uid residue formation.
It may therefore need
to be cycled periodically
to prevent this from
happening.
b. Surges of uid in a
common drain line
serving two or more
valves can be of
sufcient magnitude
to cause inadvertent
shifting of the spools.
It is recommended that
circuit protection be
used, such as separate
drain lines.
c. Control by stroke
adjusters, pilot chokes
and minimum-pilot-
pressure generator
options is described on
this page.
