Introduction

General Description

DG*V-7 valves are used pri-

marily for controlling the

starting, stopping and direc-

tion of fluid flow.

Two series of valves, DG5V

solenoid controlled, pilot

operated and DG3V pilot

operated models are avail-

able with a choice of 18 dif-

ferent 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 adjust-

ments.

Models include spring offset,

spring centered, pressure

centered and detented ver-

sions. All are available with

the option of an integral P-

port pilot pressure generator.

DG5V valves can be arranged

for internal or external pilot

pressure and/or drain con-

nections.

Features and Benefits

• High pressure and flow

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 fea-

tures, particularly for DG5V

valves, permit matching to

virtually every application

within the valve’s power

capacity.

• Optional mainstage

spool position monitor-

ing switch (CE marked)

EATON Vickers Pilot Operated Directional Valves Catalog V-VLDI-MC007-E March 2007

Application Notes

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, 4, 8, 9

and 11) with internal pilot

pressure, but they should

be used only with exter-

nally drained valves.

b. Internally drained valves

may be used only when

surges in the tank line

cannot possibly overcome

the minimum pilot pres-

sure differential referred

to above. When the possi-

bility 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 pres-

sure 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

flow conditions of the center position must

be selected with care, for the effect on both

the direction of flow and the pilot pressure.

Minimum-Pilot-Pressure

Generator

Option

Can be built into the P-port

to create a minimum pilot

pressure differential of 0,35

bar (5 psi) where internal

pilot pressure is required

with open-centered spools,

i.e. 0, 1, 4, 8, 9 and 11.

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 pres-

sure 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 adjust-

ing the stroke in one or both

directions. One use of

stroke adjusters is for con-

trolling the metering charac-

teristics of “X*” or “Y*”-

type spools. (See model

code #4.)

Pilot Choke Adjustment

Options

These provide a meter-out

flow control system to the

fluid in the pilot chambers of

main-stage valves. It allows

the velocity of the main-

stage spool to be controlled,

thereby reducing transient

shock condition. For opti-

mum results, a constant

reduced pilot pressure is

recommended.

Control Data, General

a. Dependent on the applica-

tion and the system filtra-

tion, 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

therefore need to be

cycled periodically to pre-

vent this from happening.

b. Surges of fluid in a com-

mon drain line serving

two or more valves can

be of sufficient magnitude

to cause inadvertent shift-

ing of the spools. It is rec-

ommended that circuit

protection be used, such

as separate drain lines.

c. Control by stroke

adjusters, pilot chokes

and minimum-pilot-pres-

sure generator options is

described on this page.

Performance

Characteristics

Minimum-Pilot-Pressure

Generator

For valves fitted with this

option, the P to A or B pres-

sure drop derived from the

graph on the previous page

is increased by 3,5 bar (51

psi) at 50 L/min (13 USgpm).

At any other flow rate Q1

the total pressure drop

becomes:

a. For pressures in bar and

flow rates in L/min:

= (Q

/50)

b. For pressures in psi and

flow rates in USgpm:

= 51(Q

/13.2)

Hydraulic Fluids

Materials and seals used in

these valves are compatible

with antiwear hydraulic oils,

water-glycols, water-in-oil

emulsions and non-alkyl-

based phosphate esters. The

extreme operating range is

500 to 13 cSt (2270 to 70

SUS) but the recommended

running range is 54 to 13

cSt (245 to 70 SUS). For fur-

ther technical information

about fluids see “Technical

Information” leaflet B-920 or

I-286S.

Contamination Control

Requirements

Recommendations on con-

tamination control methods

and the selection of prod-

ucts to control fluid condi-

tion are included in Vickers

publication 9132 or 561,

“Vickers Guide to Systemic

Contamination Control”. The

book also includes informa-

tion on the Vickers concept

of “ProActive Maintenance”.

The following recommenda-

tions are based on ISO

cleanliness levels at 2 m, 5

m and 15 m. For products

in this catalog the recom-

mended levels are:

Up to 210 bar (3000 psi)

20/18/15

Above 210 bar (3000 psi)

19/17/14

Fluid Temperatures

For petroleum oil:

Min. . . . . . . . .. –20˚C (–4˚F)

Max.*. . . . . .+70˚C (+158˚F)

* To obtain optimum service

life from both fluid and

hydraulic system, 65˚C

(150˚F) normally is the maxi-

mum temperature.

For other fluids where limits

are outside those of petrole-

um oil, consult fluid manu-

facturer or Eaton representa-

tive.

Whatever the actual temper-

ature range, ensure that vis-

cosities stay within those

specified under “Hydraulic

Fluids”.

plug has four leads 101,6 mm

(4.0 ) long and one of 177,8

mm (7.0 ) length. All wires

have US Underwriters
