Introduction
General Description
Eaton’s 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-3
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-3
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 trouble-
shooting
•
Simple valve removal and
replacement for service
(plug and play)
• Vibration and shock tested
• Auxiliary DIN rail mounted

ules

• Full CE electromagnetic
compatibility

plug, part no. 934939, must
be correctly fitted to ensure
that the EMC rating and

tightened with a torque of
2-2,5 Nm (1.5-2.0 lbf ft) to
effect a proper a proper seal)

When using the single
solenoid throttle valves
version (K*FT) a parallel
flowpath module (page 12)
can used to approximately
double the flow rate.
KBF valves are preset at the
factory to compensate for
the effect of spool overlap.
Curves shown include
deadband compensation
provided for the KF valve
by Eaton’s Vickers Eurocard

NOTE: For optimum valve

the proportional solenoids at
initial start-up. This may be
done as follows:
• The valve may be pres-

bubbles appear and then
reinstalling bleed screws,

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

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 conversions are
accurate to 0.01” unless
otherwise 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

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

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).
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.
