Introduction
General Description
The KBSDG4V-3 line offers a
range of proportional
directional valves with
integral control electronics.
Factory-set adjustments of
gain and offset ensure
consistent reproducibility
valve-to-valve.
These four-way solenoid
operated proportional valves
have a high dynamic
performance which enables
them to be used in closed-
loop applications, previously
possible only with servo
valves. Various spool options
are available for rated flows
up to 40 L/min (10.6
USgpm). Working pressures
are to 350 bar (5000 psi). The
spool position is monitored
by an LVDT which feeds back
information to the amplifier,
enabling spool position to be
accurately maintained.
This valve type can be
supplied with or without an
integral amplifier built
directly onto the valve.
KSDG4V-3
Without the integral amplifier.
Features and Benefits
• Wide range of spool and
flow rate options.
• Supported by a broad
range of amplifiers and
auxiliary function modules.
• Electronic feedback LVDT
ensures accurate spool
position control.
• Internal current feedback
provides optimal control.
• Vibration and shock
tested.
• Full CE electromagnetic
compatibility.
KBSDG4V-3
With integral control
electronics.
Factory-set adjustments of
gain and offset ensure
consistent repeatability
valve-to-valve.
The only electrical inputs
required are power supply
(24V) and a command signal,
either ±10V or 4-20 mA
(model code selectable). The
amplifier is housed in a
robust metal enclosure,
sealed against ingress of
water and other fluids.
Electrical connections are via
a standard 7-pin plug.
A spool position monitor pin
allows the function of the
valve to be electrically
monitored. Ramp functions,
if required, can be generated
externally.
Features and Benefits
• Factory-sealed
adjustments ensure valve-
to-valve reproducibility.
• Installation wiring reduced
and simplified.
• Standard 7-pin connector.
• Standard 24V DC supply
with wide tolerance band.
• Optional command signal,
±10V or 4-20 mA (model
code selectable).
• Valve with integrated
amplifier selected,
ordered, delivered and
installed as one
performance-tested
package.
• Spool position monitor pin
to help with
troubleshooting.
• Simple valve removal and
replacement for service
(plug & play).
• Vibration and shock
tested.
• Auxiliary DIN rail mounted
electronic function
modules available.
• Full CE electromagnetic
compatibility.
• IP67 valve, environmental
protection rating.
• Optional valve enable
function.

WARNING
Valves with integral
amplifiers are
supplied with or without the
metal 7-pin plug.
The Vickers™ plug, part
no. 934939, must be
correctly fitted to ensure that
the EMC rating and IP67
rating are achieved. The plug
retaining nut must be
tightened with a torque of
2-2,0 Nm (1.5-2.5 lbf ft) to
effect a proper seal.

Subplates and
Mounting
Surfaces
General Description
If a subplate is not used, a
machined pad must be
provided for valve mounting.
Pad must be flat within
0,0127 mm (.0005 inch) and
smooth within 1,6 µm (63
microinch). Mounting bolts,
when provided by customer,
should be ISO 898 class 12.9
or better.
Dimensional Tolerances
Dimensional tolerance on
interface drawings is
±0,2 mm (±0.008”) except
where otherwise stated. ISO
4401 specifies inch
conversion to ±0.01”.
Conversion from Metric
ISO 4401 gives dimensions
in mm. Inch conversions are
accurate to 0.01” unless
otherwise stated.
Mounting Bolt Tappings
ISO 4401 gives metric thread
tappings. Alternate UNC
tappings are Eaton
recommendations that allow
these plates and associated
valves to be used up to their
maximum pressures, when
using Eaton recommended
bolt kits, or bolts of an
equivalent strength. It is
recommended that
Customer’s own manifold
blocks for UNC bolts should
be tapped to the minimum
depths given in the
footnotes.

Electromagnetic
Compatibility (EMC)
It is necessary to ensure that
the valve is wired up as
above. For effective
protection the user electrical
cabinet, the valve subplate or
manifold and the cable
screens should be
connected to efficient
ground points. The metal 7
pin connector part no.
934939 should be used fo r
the integral amplifier.
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.
It is important to connect the
0V lines as shown above.
The multi-core cable should
have at least two screens to
separate the demand signal
and monitor output from the
power lines.
The enable line to pin C
should be outside the screen
which contains the demand
signal cables.

Application
Data
Fluid Cleanliness
Proper fluid condition is
essential for long and
satisfactory life of hydraulic
components and systems.
Hydraulic fluid must have the
correct balance of
cleanliness, materials and
additives for protection
against wear of components,
elevated viscosity and
inclusion of air.
Recommendations on
contamination control
methods and the selection of
products to control fluid
condition are included in
Eaton’s publication 9132 or
561, “Vickers™ Guide to
Systemic Contamination
Control”. The book also
includes information on the
Eaton concept of “ProActive
Maintenance”. The following
recommendations are based
on ISO cleanliness levels at 2
µm, 5 µm and 15 µm.
For products in this catalog
the recommended levels are:
0 to 70 bar (1000 psi):
18/16/13
70+ bar (1000 + psi):
17/15/12
Eaton products, as any
components, will operate
with apparent satisfaction in
fluids with higher cleanliness
codes than those described.
Other manufacturers will
often recommend levels
above those specified.
Experience has shown,
however, that life of any
hydraulic components is
shortened in fluids with
higher cleanliness codes
than those listed above.
These codes have been
proven to provide a long
trouble-free service life for
the products shown,
regardless of the
manufacturer.
Hydraulic Fluids
Materials and seals used in
these valves are compatible
with antiwear hydraulic oils,
and non-alkyl-based
phosphate esters. The
extreme operating viscosity
range is 500 to 13 cSt (2270
to 70 SUS) but the
recommended running range
is 54 to 13 cSt (245 to 70
SUS).
Installation
The proportional valves in
this catalog can be mounted
in any attitude, but it may be
necessary in certain
demanding applications, to
ensure that the solenoids are
kept full of hy
draulic fluid.
Good installation practice
dictates that the tank port
and any drain port are piped
so as to keep the valves full
of fluid once the system
start-up has been completed.

Service Information
The products from this range
are preset at the factory for
optimum performance;
disassembling critical items
would destroy these
settings. It is therefore
recommended that should
any mechanical or electronic
repair be necessary they
should be returned to the
nearest Eaton repair center.
The products will be
refurbished as necessary and
retested to specification
before return.
Field repair is restricted to
the replacement of the seals.
Note:
The feedback/solenoid
assembly installed in this
valve should not be
disassembled.
