shifted.

• A “P12L”- model offers a junction box with

rectifier, lights and plug-in coils for quick and
easy solenoid changing without removing the
valve from the machine.
• Installed cost and space savings from higher
power/weight-and-size ratios.
• Reduced internal leakage reduces power losses,
increases system efficiency: the result of improved
manufacture of spool and bores.
• Installation flexibility resulting from a choice of
numerous combinations of solenoid connectors
and locations.
• Multi-fluid capability without need to change
seals.
• Higher sustained machine productivity and higher
uptime because of proven fatigue life and
endurance, tested over 20 million cycles.
• Solenoid coils can be changed quickly and easily
without leakage from hydraulic system.
• Compact, cost effective system design when used
with Vickers SystemStak™ valves and multi-port
subplates.

 As system flow increases the minimum pilot pressure required increases. These spools will operate satisfactorily in excess of
946 l/min (250 USgpm) with higher pilot pressures.
NOTE: For the type 52 spool flow recommendations contact your Vickers representative.
 Fast valve switching of large oil volumes, without adequate decompression circuitry, can develop instantaneous flows well
above the maximum ratings. The type 8 spool may spin within the body, causing unusual valve body bore wear when applied in
this type of circuit. With this and other spool types, valve malfunction might occur. Where these applications exist use the DG5S4-10**-S534
special designator for the 4C and 8C anti-spin spools/spring.

WARNING: Electromagnetic Compatibility (EMC)

It is necessary to ensure that the unit is wired up in accordance with the connection arrangements shown above.
• For effective protection the user’s electrical cabinet, the valve subplate or manifold and the cable screens should be
connected to efficient ground points.
In all cases both valve and cable should be kept as far away as possible from any sources of electromagnetic
radiation such as cables carrying heavy current, relays and certain kinds of portable radio transmitters, etc. Difficult
environments could mean that extra screening may be necessary to avoid the interference.

§ Internal drain models drain the pilot valve through the tank port of the mainstage. External drain models drain the pilot valve through the ‘‘Y’ port of the mainstage. To provide proper operation w ithout malfunction, the
pilot pressure must alw ays exceed tank or drain line pressure by the minimum pilot pressure required per valve and spool type (see charts on page 16). Tank or drain line surges w hich w ould reduce this differential are to
be avoided as they may cause the mainstage to shift. M ainstage tank pressure is limited to the tank line rating of the pilot valve on internally drained models (w ith ‘‘T’’ included in the model code). Internal drains may be
used w ith all models except pressure centered ‘‘D’’ models. Pressure centered models must be externally drained through ‘‘Y’’ and ‘‘W ’’ ports. To achieve the maximum tank line rating of 350 bar (5000 psi) of the mainstage,
an external pilot drain must be used and it is recommended that a separate line be provided directly to the tank.

X - Fast Response
Use of this option decreases
the shift time and increases
the system shock genera-
tion. This requires the
removal of an orifice plug
w ithin the mainstage body. It
is available on all models by
adding ‘‘X’’ to the model
code. Example: DG5V-8-(* )-
2C-X-(* )-10
When a standard
performance pilot is
selected and pilot
pressure is above 3000 psi,
the reducer module is
required to limit high drain
line pressure transients gen-
erated during shifting.

1. Open Center Spools (0, 1, 9 and 11 types): Open center

valves are used in single operations where no other
operation is performed by the same source of power and
where cylinders do not have to be held by pressure. Open

type is generally used to operate a cylinder. When the spool
is centered, a cylinder port is blocked and the cylinder is held
in a definite position. In some circuits, flow from the tank port
is piped into the pressure port of another valve. This allows
the same source of power to operate two different cylinders.
This type of arrangement may be used in a system
containing a number of operations. However, each operation T A P B

 B. Wet Armature Type Solenoids: Wet armature
solenoids are standard on DG4V-3, DG4S4-01-60, and
DG4V4-01 pilot valves only. Wet armature solenoids have
many design advantages over other types of solenoids.
Some advantages include cooler operation, static sealing
arrangements, immunity to moisture and greater burn-out
resistance.DG4V-3 and DG4S4-01* wet armature solenoids
are not serviced with individual parts. Service is provided by
replacing the entire core tube subassembly. Parts can be
removed, cleaned and seals replaced on ‘‘W3’’ type
Figure 12a. Flow Conditions solenoids.
Pressure to ‘‘B’’ - ‘‘A’’ to Tank
C. Air Gap Solenoids: DG4S4-01 pilot valves are usually
equipped with air gap solenoids. Air gap solenoids are isolated
from system fluid and can be removed and replaced without
disturbing the system. A push pin and sliding seal couple the
solenoid to the valve spool (see Figures 13a and 13b).
E. Electrical Solenoid Voltage Requirement: Electrical
solenoids are available in various AC and DC voltage
ranges. The standard voltage and frequency range is 115V
AC, 60 Hz. Refer to parts and service drawings for units with
non-standard voltage ranges. Fifty (-50) and fifty-one (-51)
Figure 12b. Flow Conditions
Pressure to ‘‘A’’ - ‘‘B’’ to Tank design units have the voltage and frequency range stamped
into the nameplate if other than standard. Ten (-10), twenty
(-20) and fifty-three (-53) design units use an identification
letter for the coil voltage and frequency.
F. Electrical Solenoid Ground Connections and Wiring
Housing: An electrical wiring housing with a 1/2” NPTF
thread connection is available on DG4V-3 and DG4S4-01
pilot valves. the wiring housing can be rotated 180 from the
position shown in Figure 13a. Wire grounding screws are
provided for convenience.

DG3S-8-**-10 Adjustment Options

Pilot Choke Adjustment(s)

Pilot choke is adjusted by backing off Millimeters (inches) 167,0 (6.57)
locknuts and turning adjusting screws
84,0
inward (clockwise) to decrease rate of (3.31)
spool travel and outward
(counterclockwise) to increase the rate.
Pilot oil for models with this feature DGMFN-3-*-40
Pilot choke adjustment
should be taken from a source having a
constant pressure. See spool control 173,0
modifications in model code. (6.81)
Stroke adjustments

Stroke Adjustment(s)
134,4
Stroke adjustment limits movement of (5.29)
the main stage spool. Backing off the
jam nut and turning the adjusting screw
41,0
inward (clockwise) decreases spool (1.61)
stroke. See spool control modifications
in model code.
172,2 (6.78) 172,2 (6.78)

Spring Offset Pilot

Operated Models
DG3S-8-*A-10
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
atmospheric pressure through a
surge-free line. Back pressure at this 146,1 (5.75)
connection would cause valve
malfunction. 268,6
(10.57)
NOTE: High assembled spring load. Call
Vickers Service for disassembly instructions.

Pressure Centered Pilot

Operated Models 306,4 (12.07)
DG3S-8-*D-10
183,9 (7.24)
This option provides faster spring
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.

As system flow increases the minimum pilot pressure required increases. These spools will
operate satisfactorily in excess of 946 l/min (250 USgpm) with higher pilot pressures.

 Fast valve switching of large oil volumes, without adequate decompression circuitry, can
develop instantaneous flows well above the maximum ratings. The type “8” spool may spin within
the body, causing unusual valve body bore wear when applied in this type of circuit. With this and
other spool types, valve malfunction might occur. Where these applications exist, use the
DG3S4-10-5*-S534 special designator for the 4C and 8C anti-spin spool/spring.

Spring Offset Models

DG3S4-102A-5*
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
atmospheric pressure through a
surge-free line. Back pressure at this
connection would cause valve
malfunction.
NOTE: High assembled spring load. Call 423,2
Vickers Service for disassembly instructions. (16.66)

Pressure Centered Models

DG3S4-102D-5*
This option provides faster spring
209,6
centering time by using pilot pressure to (8.25)
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 187,5
by pilot pressure and centering springs. If (7.38)
pilot pressure fails or falls below the
required minimum of 10,3 bar (150 psi)
the spool will return to center position at
minimum pilot pressure flow rates for
pressure centered valves.

Installation data:
Mounting attitude No restrictions except for no-spring detented model
DG4V-2-*N. It should be mounted with the spool
axis horizontal. This model type may be affected by
severe vibration or shock, especially if a solenoid is
not held energized.
Operating Considerations
1. Dependent on the application and system filtration, any sliding spool
valve if held shifted under pressure for long periods of time, may
stick and not move readily due to fluid residue formation. It may need
to be cycled periodically to prevent this from happening.
2. Surges of fluid in a common tank line serving two or more valves can
be of sufficient magnitude to cause inadvertent shifting of these
valves. This is particularly critical in no-spring detented models.
Separate drain lines are recommended.

DGMR(1)-2-1* series
DGMX2-2-1* series
General description Typical Sectional Views
These single stage valves operate by DGMX2-2-P*-*W-10
the application of pressure on the end of
the valve spool, acting against a spring
which is loaded by means of the manual
adjustment mechanism.

In the counterbalance and sequence

valves, the spool is offset by the spring
such that flow cannot pass through the
valve. When the force exerted by the
pilot pressure on the spool end exceeds DGMR1-2-PP-*W-10
the force of the main spring, the spool is
moved to allow flow through the valve.

In the pressure reducing valve, the

flow path is normally open and is
closed as the pilot pressure exceeds
the manual setting of the valve.
Excessive pressure in the reduced
pressure line is prevented by a
pressure relieving function.

Pressure adjustment options are

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 flow rate can be controlled.
Stroke adjusters can be fitted 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 .)

General Description
These valves are used for controlling the
starting, stopping and direction of fluid
flow.
Two types of control are available:
– Hydraulic pilot pressure (DG3V-5
models)
– Integrally-mounted solenoid operated
pilot valves (DG5V-5 models)
comprising spring-offset, spring-
centered and detented versions.
Pilot pressure and drain can be
independently configured for internal
or external connection.

All spool types have been designed to

provide good low-shock, fast-response
characteristics which can be enhanced
by an optional pilot choke module to
control the speed of travel of the main
spool.

Note
When solenoid “a” is energized, flow is always P A. When solenoid “b” is energized, flow is always P B. This is in accordance
with the ANSI-B93.9 standard. Standard spring offset valves are assembled right hand, such that flow is P A in the spring offset
position (solenoid is de-energized). Solenoid “a” and “b” are identified on the diagram plate.
1. Pressure drop data gives
approximate pressure drop
(∆P) when passing 21 cSt (100
SUS) fluid(s) having .865 specific
gravity.

2. For any other viscosity(s), the

pressure drop (∆P) will change as
follows:
Viscosity

(Approx.)

3. For any other specific gravity (G1)*,

the pressure drop (∆P1), will be
approximately:
∆P1 = ∆P(G1/G)

* Specific gravity of fluid may be obtained from

its producer. The value is higher for fire-resistant
fluids than for oil.

 Maximum flow is dependent upon the valve type used and is subject to variation due to
changes in operating pressure or tank line back pressure. If operating pressure and tank line
back pressure simultaneously approach maximum, or if higher flow rates are desired, contact

Electrical Information
Solenoids
Solenoids on models listed are for
115V AC - 60 Hz service. Solenoids for
other voltages and frequencies are
available. Specify in model number if
other than 115V AC - 60 Hz service is
desired. See model code for options.

Note
Solenoids are designed to function
continuously at "10% of the rated
voltage.

Note
All solenoid coil wire insulation is
Class “F”. Standard solenoid coil
lead wire has Class “A” insulation.
“F3” solenoid coil lead wire is
Class “F”.

Solenoid Energizing
Spring centered and spring offset types
will be spring positioned unless solenoid
is energized continuously. No-spring
detented valves may be energized
momentarily, approximately 0.1 second;
when solenoid is de-energized spool will
remain in last position attained provided
there is no shock, vibration, or unusual
pressure transients.

WARNING: Electromagnetic Compatibility (EMC)
It is necessary to ensure that the unit is wired up in accordance with the connection arrangements shown above. For
effective protection the user’s electrical cabinet, the valve subplate or manifold and the cable screens should be
connected to efficient ground points.
In all cases both valve and cable should be kept as far away as possible from any sources of electromagnetic
radiation such as cables carrying heavy current, relays and certain kinds of portable radio transmitters, etc. Difficult
environments could mean that extra screening may be necessary to avoid the interference.

The reducer module is required for Air
Gap and Wet Armature piloted models 314,5
when pilot pressure exceeds 210 bar DGMX2 (12.38)
(3000 psi). These two–stage spool
valves maintain a reduced outlet
pressure against variations in inlet
pressure. These valves are able to act
as relief valves (at 50% of the maximum
flow) to prevent excess pressure being

Pressure Centered Pilot Operated
147,3
Models (5.80)
This option provides faster spring
centering time by using pilot pressure to
center the spool. The centering springs
254,5
are used in addition to pilot pressure to (10.02)
ensure 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. 467,4 (18.4)

Integral Check Valves

For internal pilot pressure, an integral
pressure port check valve is required for
internally piloted valves with open center
spools (0,1,4,8 & 9). The pilot pressure Pressure Drop Across Check Valve
generated is the total of: P→T drop FLOW – USgpm
through the valve in center condition, 25 75 125 175 225
the pressure drop through the check 20 300
valve, plus the pressure at the tank port.

For proper operation, the total pressure
drop must be greater than the minimum 16 240

required pilot pressure (see chart). To

prevent load drop, a check valve in the 12 200
pressure port can be used to prevent
reverse flow from ‘‘A’’ cylinder port to 10 160
pressure port. If using as reverse flow
check, maximum reverse pressure is

Ordering Procedure
2. Check for correct plug function by
illumination/non-illumination of the Order plug by full model code, and
LED: spare interface seals by part number
a. Apply less than 2 to 3 volts to the 732100.
input terminal: the LED should not
be illuminated.
b. Increase voltage: the LED should
illuminate when the voltage reaches
15V. Do not exceed 30V command
signal.
c. Decrease voltage: the LED should
go off when the voltage is less than
5V.
If there is a malfunction a new plug
must be fitted.

3. Switch off power supply and

command/input signal and then
install plug on solenoid. Ensure that
all seals are fitted correctly and
clamped as the retaining screw is
tightened: this is essential in
providing IP67 protection.

4. Ensure that the hydraulic system will

not cause any erratic movement of
actuators, then:
– Switch on power supply again.
– Repeat LED/function check as in 2.
An LED malfunction now indicates a
short circuit at the load.

5. Successful completion of these

checks means that the plug and load
are ready for use.

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 flow rate can be controlled.
Stroke adjusters can be fitted 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 5 .)

Pressure Drop Characteristics

Typical under standard test conditions, i.e. with oil at 21 cSt (105 SUS) and of 0.865
specific gravity. For other viscosities the pressure drops shown below will change
approximately as follows:

93 111 119 126 132 137 141
A change to another specific gravity will yield an approximately proportional
change in pressure drop.

The specific gravity of a fluid may be obtained from its producer. Fire-resistant
fluids usually have higher specific gravities than oil.

be used to prevent reverse flow from a 0 95 190 285 380
cylinder port to the pressure port. FLOW – L/min

For minimum pilot pressure table see

page 7

Pressure Centered Valves

This option provides faster spring
centering time by using pilot pressure to 306,4 (12.07)

center the spool. The centering springs

183,9 (7.24)
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 when both solenoids are
de-energized. 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. Pilot
pressure is not available through use of
an integral check valve. The pressure
centering times for pressure centered
models are shown in curves for various
pilot pressures. See page 6.

NOTE:
a) Pilot pressure must always exceed drain line pressure or, for internally drained valves, the T-line pressure
by at least the requisite minimum pilot pressure. Open-center spools (0, 1 and 8) should be used only in 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.

Full flow
Restricted flow
NOTE:
a) Pilot pressure must always exceed drain line pressure or, for internally drained valves, the T-line pressure
by at least the requisite minimum pilot pressure. Open-center spools (0, 1 and 8) should be used only in 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.

Introduction

DG5S4-04 models are two-stage

directional valves having an integrally
mounted DG4V-3(S)-60 pilot valve.

These valves are generally used to

control the direction of flow in a
hydraulic circuit. This in turn would
control the movement of a work cylinder
or the rotation of a fluid motor.

Features and Benefits

Suitable for the most demanding
industrial applications with flow
capacities up to 227 l/min (60 USgpm)
and rated pressure of 210 bar
(3000 psi).

Available with a wide variety of spool

and spring arrangements, stroke and
pilot choke adjustments, integral check
valves, and port orifices.

Solid cast body with cored passages

for maximum strength and minimal
pressure drop.

Designed and manufactured by

Vickers, with over 70 years as the
global leader in fluid power and motion
control.

Note
When solenoid “a” is energized, flow is always P to A. When solenoid “b” is energized, flow is
always P to B. This is in accordance with the ANSI-B93.9 standard. Standard spring offset valves
are assembled right hand, such that flow is P to A in the spring offset position (solenoid is
de-energized). Solenoid “a” and “b” are identified on the diagram plate.

* As system flow increases the minimum pilot pressure required increases. These spools will operate satisfactorily in excess of 227 l/min
(60 USgpm) with higher pilot pressures.
 Maximum flow limited to 170 l/min (45 USgpm) @ 69 bar (1000 psi), 76 l/min (20 USgpm) or 45 l/min (12 USgpm) @ 210 bar (3000 psi).
 Fast valve switching of large oil volumes, without adequate decompression circuitry, can develop instantaneous flows well
above the maximum ratings. The type 8 spool may spin within the body, causing unusual valve body bore wear when applied in
this type of circuit. With this and other spool types, valve malfunction might occur.
