Introduction
General Description
Eaton Vickers
®
K(B)FD/
TG4V proportional valves
are designed to provide
a controlled oil flow in
direct proportion to a
command signal. They are
available in two types; a
double solenoid version
that will provide reversible
flow to an actuator and
a single solenoid throttle
version that provides a
single direction of flow.
Hydrostats are available
for load compensation and
parallel flow path modules
are available that will boost
the flow capacity of single
solenoid throttle versions
to nearly twice that of the
standard valve.
Additionally, both of these
valve types can be supplied
with or without an integral
amplifier built directly onto
the valve.
KFD/TG4V-5
This version is supplied
without the integral
amplifier.
Features and Benefits
Wide range of spool and
flow rate options.
Electronic feedback LVDT
ensures accurate spool
position control.
Vibration and shock
tested.
Supported by a broad
range of amplifiers
and auxiliary function
modules.
Full CE electromagnetic
compatibility.
KBFD/TG4V-5
A range of proportional
directional and throttle
valves with integral control
electronics. Factory-set
adjustments of gain, spool
deadband compensation
and offset ensure consistent
repeatability valve-to-valve.
The only electrical inputs
required are power supply
(24V) and a voltage
command signal of
±10V
or 4-20 mA. 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 adjust-
ments ensure valve-to-
valve reproducibility.
Installation wiring reduced
and simplified.
Standard 7-pin connector.
• Standard 24V DC supply
with wide tolerance band.
• Optional
±10V DC or 4-20
mA command signals.
• Valve with integrated
amplifier selected,
ordered, delivered and
installed as one perfor-
mance-tested package.
• Spool position monitor pin
to help with troubleshoot-
ing.
• Simple valve removal and
replacement for service
(plug & play).
• Vibration and shock tested.
• Auxiliary DIN rail mounted
electronic function mod-
ules available. Full CE
electromagnetic compat-
ibility.
• IP65 & IP67 valve environ-
mental protection rating.
• Optional valve enable
function.

WARNING
Valves with

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 archieved.
The plug retaining nut must
be tightened with a torque
of 2-2,5 Nm (1.5-2.0 lbf ft)
to effect a proper a proper

Spool types as noted
When using the single
solenoid throttle valve
(K*FT), a dual flowpath
module (page 16) can be
used to approximately
double the flow rate.
Curves shown include
deadband compensation
provided for the KF valve by
the Eaton’s Vickers Eurocard
Amplifier EEA-PAM-535-*-32
(user adjustable).
KB valves are preset at the
factory to compensate for
the effect of spool overlap.

NOTE: For optimum valve
operation, bleed the air from
the proportional solenoids at
initial start-up. This may be
done as follows:
• The valve may be pres-
surized by removing the
bleed screws until no
bubbles appear and then
reinstalling bleed screws,
or...
Remove both bleed
screws, and use a stan-
dard oil can nozzle to
pump fluid in one side
until it flows, free of air
bubbles, out the other
side. Reinstall screws.
If there is no inherent back
pressure in the tank port of
the circuit do not allow the
tank line to empty. This may
be prevented by installing a
check valve in the tank line.
The cracking pressure of the
check valve should be in the
range of 22 - 45 psi (1.5 - 3
bar).

Warning
Valves with integral
amplifiers are
supplied with or without the
metal 7-pin plug. The Eaton
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
2,0-2,5 Nm (1.5-2.0 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 for Metric
ISO 4401 gives dimensions
in mm. Inch conversons are
accurate to 0.01” unless
othewise stated.
Mounting Bolt Tapping
ISO 4401 gives metric
thread tappings. Alternate
UNC tapping are Eaton’s
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.

Feature
Note: In applications
where the valve must
conform to European
RFI/EMC regulations, the
outer screen (shield) must
be connected to the outer
shell of the 7-pin connector,
and the valve body must
be fastened to the earth
ground. Proper earth
grounding practices must
be observed in this case, as
any differences in command
source and valve ground
potentials will result in a
screen (shield) ground loop.
WARNING
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 for the integral
amplifier. In all cases both
valve and cable should be
kept as far away as possible
from any sources of elec-
tromagnetic 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

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’s 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). For further technical
information about fluids see “Technical Information” leaflet
B-920 or I-286S.
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 hydraulic 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.
