General description

The Size 8 Directional

Control Valve serves as a

control valve package. It

offers directional control,

pilot pressure reducers, pilot

chokes, and main stage

stroke adjustment to control

the ow.

The valves are generally

used to control large ows

up to 700 l/min (185 USgpm)

at 350 bar (5000 psi) and

provide low pressure drops.

The range includes:

• DG3V-8 - remote pilot

operated valve.

• DG5V-8-H - DG4V-3-60

high performance D03

pilot valve 210 bar (3000

psi) tank line rating.

Each valve contains a

mainstage spool which is

positioned in the valve by

special arrangement. The

four arrangements are:

• Spring offset - For single

stage operation, one

spring returns spool to

an offset position. For

two–stage operation,

springs and washers

are removed from main

stage and offset action is

obtained from pilot valve.

• Spring centered - Spring

and washer are located

on both ends of main

stage spool to control

centering.

• Pressure centered -

Centering springs are

used in addition to pilot

pressure, to provide

positive centering should

pilot pressure fail.

• No–spring detented -

Springs and washers are

provided so that in the

event of pilot pressure

failure, the main spool

will spring center.

Features and Benets

• A ‘‘mini-system’’

capability with wide

variety of spool and

spring arrangements,

stroke and pilot choke

adjustments, integral

check valves and port

orices.

• High force solenoids and

centering springs assure

consistent shifting

through a wide range

of pressure and silting

extremes.

• Optional Mainstage

Spool Position

Monitoring Switch

(CE marked)

• Suitable for demanding

industrial or mobile

applications by providing

for reliable operations.

• Endurance tested to 10

million cycles and fatigue

tested without failure to

ensure highest reliability.

• Fatigue testing

performed to NFPA

specications to ensure

the highest reliability in

applications requiring

high ows and pressure.

• Solid cast body and

cored passages for

maximum strength and

minimal pressure drop.

• Electrical options

including coil types,

connections, and wiring

housings allow full

compatibility and reliable

performance in any

system application.

• Plain, waterproof, and

lockable manual override

options are available

to facilitate system

troubleshooting or

servicing.

Application Notes

General Description

DG5V-8 models are two-

stage directional control

valves having an integrally

mounted wet armature

solenoid pilot valve. These

valves are generally used to

control the movement of a

work cylinder or the rotation

of a uid motor.

Pressure Centered Models

Designated by ‘‘D’’ under

spring/spool arrangement in

model code.

This option provides faster,

more positive spring

centering time by use of pilot

pressure to center the spool.

The valve spool is returned

to center position when

pilot pres sure is applied at

both ends of the spool. The

centering springs are used in

addition to pilot pressure to

ensure positive centering of

spool.

If pilot pres sure fails or falls

below the required minimum,

the spool will spring return to

the center position. Pilot pres

sure is not available through

the use of and integral check

valve. Pressure centered

valves have a drain port ‘‘W’’

and must have provisions for

this feature.

Note

Pressure centered valves require

a pilot valve which directs pilot oil

to connections ‘‘X’’ and ‘‘Y’’ of the

valve at the same time pressure

centering is desired. The centering

time depends on the rate of

pressure rise in the pilot chamber.

Spring Offset Models

Designated by ‘‘A’’ under

spring/spool arrangement in

model code.

Spring offset model has an

internal spring which returns

the spool to offset position

when the pilot connection

‘‘X’’ is open to tank. Pilot

connection ‘‘Y’’ becomes a

drain connection and must

be pioped directly to tank

at atmospheric pressure

through a surge-free tank

line. Back pressure at this

connection would cause

valve to malfunction.

Caution: Spring offset

models contain a high

assembled spring load. Call

Eaton Service for disassembly

instructions.

Spring Centered Models

Designated by ‘‘C’’ under

spring/spool arrangement in

model code.

A spring and washer

arrangement is used on

both ends of the spool. If

control pressure is removed,

the valve will go to center

position due to spring force.

No-Spring Models

Designated by a ‘‘Blank’’

under spring/spool

arrangement in model code.

When the solenoid is de-

energized, the spool returns

to the last position attained.

Performance Characteristics

Spring centered, pressure

centered and spring offset

models require continuous

pilot pressure to maintain

shifted position. Spring

centered models return valve

spool to center position by

centering springs when pilot

pressure fails or falls below

minimum requirement.

Shift Times

Shift times are dened as

the time from pilot pressure

application/removal to

the point of the s tart of

a pressure rise/decline in

appropriate port.

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 pres

sure. (The “9” main spool will not

ensure sufcient pilot pressure in

the center position for internal pilot

pressure models).

Pressure centered models:

Valve spool is returned

to center position by pilot

pressure, when pilot

pressure is removed. If pilot

pressure fails or falls below

the required minimum, the

valve spool will spring return

to center position. (At spring

centered valve ow rates ).

Caution: Surges of oil in

a common tank line

serving these and other valves

can be sufcient enough to cause

inadvertent shifting of these valves.

This is very critical in the no-spring

detented 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 s tick and

not spring return due to uid residue

formation and therefore, should be

cycled periodically to prevent this

from happening.

Shifting Action

The pilot valve solenoids of

spring centered, pressure

centered, and spring offset

models must be energized

continuous ly to keep the

main stage spool in the

shifted position. No-spring

detented models only need

to be energized momentarily

(for approximately 0.1

second).

Spring centered and pressure

centered models return the

valve spool to the center

position when both solenoids

are de-energized or pilot

pres sure fails or falls below

minimum requirements.

Spring offset models return

the spool to the offset

position by pilot pres sure

when the solenoid is de-

energized.

When no-spring detented

models are de-energized, the

pilot and main spools remain

in their las t position as long

as there are no unusual

shock, vibration, or pressure

transients, and the spool axis

is horizontal. If pilot pressure

fails or falls below minimum

requirements, the main spool

will spring center (at spring

centered ow rates ), but

will not drift to a reversal of

ow position. The pilot stage

will remain in the detented

position.

When used as other than a

normal 4–way valve, consult

your Eaton representative.

The DG5V, 10 design two-stage valves have been designed to satisfy the needs of most applications.

Consult your Eaton representative about an alternative model if:

a) Valves are required to remain pressurized for long periods without frequent switching, and /or

b) Back pressure on the drain port of externally drained models (or the tank port of internally drained models) is required to rise above 350 bar (5000 psi).

* The method for verifying the rated fatigue pressure of the complete unit conforms to NFPA/T2.6.1 R1-1991 (Catalog C/90), Fluid Power Systems and Products method for verifying the

fatigue pressure rating of the pressure containing envelope.

§ 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 without malfunction, the pilot pressure must always 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 which would reduce this differential are to be avoided as they may cause the mainstage to shift. Mainstage tank pressure is limited to the tank line

rating of the pilot valve on internally drained models (with ‘‘T’’ included in the model code). Internal drains may be used with 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.

Integral Check Valves

For internal pilot pressure, an integral

pressure port check valve is available. This

back pressure will be present at the cylinder

ports. The pilot pressure generated is the

total of: PT drop through the valve in

center condition, pressure drop through the

check valve, plus the pressure at the tank

port.

To prevent load drop, a check valve in

the pressure port can be used to prevent

reverse ow from a cylinder port to the

Response Times

Response times are dened

as the time from solenoid

energization/de-energization

to the point of the start of

a pressure rise/decline in

appropriate port.

Solenoid Energizing

Spring centered, pressure

centered and spring offset

DG5V-8 types must be

energized continuously.

No-spring detented

DG5V-8 type may be

energized momentarily.

Pressure centered and spring

centered DG5V-8 types

return valve spool to center

position when both solenoids

are de-energized.

Mounting Position

No–spring detented valves

must be installed with the

longitudinal axis horizontal

for good machine reliability.

The mounting position

of spring centered and

spring offset models is

unrestricted provided that

the pilot pressure supply

is maintained as required.

(Spring offset valves do not

have a spring in the main

spool section).

Optional Features

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 generated

is the total of: PT drop

through the valve in center

condition, pressure drop

through the check valve, plus

the pressure at the tank port.

For proper operation, total

pressure drop must be

greater than the minimum

required pilot pressure (see

chart). To prevent load drop,

a check valve in the pressure

port can be used to prevent

reverse ow from a cylinder

port to pressure port. If

using as reverse ow check,

maximum reverse pressure

is limited to 210 bar

(3000 psi).

Optional Features

Pilot Choke

DGMFN-3-Y-A2W-B2W-41

Pilot choke increases the

amount of time to shift the

mainstage spool, lowering

the possibility of large ow

transients in the circuit.

It is adjusted by backing

off locknuts and turning

adjusting screws inward to

decrease rate of spool travel

and outward to increase

spool travel rate. See spool

control modications in

model code.

Stroke Adjustment

Stroke adjustment limits

movement of the mainstage

spool. Backing off the jamnut

and turning the adjusting

screw inward decreases

spool stroke. See spool

control modications in

model code.
