General Description
The Parker D1FH valve is a high response pro-
portional servo valve with an on-board drive
amplifier.TheD1FHincorporatestheuseofstate-
of-the art drive electronics with an LVDT for
continuous monitoring of the spool position. Zero
lapspoolsareavailableforclosedloopapplications
with two different 'power down' configurations.
The valve features frequency response levels
greater than 100 Hz, along with low hysteresis
and exellent repeatability.
Operation
The D1FH valve uses a precision lapped spool
and sleeve configured with four control positions.
During normal operation the valve will shift from
the center position to either side providing flow
out the 'A' or 'B' port. When the enable signal is
removed from the drive amplifier, the valve will
shift to a fourth position. The fourth position will
block all four ports in one version. A second
version that is available will block the 'P' port and
allow the 'A' and 'B' ports to bleed to the 'T' (tank
line).
Note
The tank line to the valve must have a minimum
pressureof(1.4bar).Maximumpressureis35bar
(500 PSI).
Features
• On-Board Electronic Drive Amplifier
Integral electronics eliminates the need for
costly wiring between the valve and driver
card. The unit is shipped as a factory preset
and tested unit.
• High Frequency Response
The valve features a very high frequency
response which is necessary for many closed
loop applications.
• Four Position Spool Capability
The four position spool provides predictable
flow in the event of a power failure to the
drive electronics, within the limits of the power
curve.
• 315 bar Pressure Capability
The maximum operating pressure rating for
the D1FH is 315 bar or 4500 PSI (40 L/M
version limited to 210bar).
• Spool Position Feedback
The LVDT continuous feedback monitoring
circuit provides low hysteresis and exellent
repeatability.
• Contaminant Sensitivity
The D1FH operates with standard mineral oil
based fluids with a cleanliness level of ISO
Class 16/13, SAE Class # 4.
• Drive Enable Feature

signal,(5 to30 VDC),is notpresent. Thevalve
will then shift to the fourth position flow path
selected by the user (E50 or E80 spool).

mendations, mounting restrictions and other
general installation instructions.

Initial Startup
• With no command input, turn on DC power.
• Turn on the Enable signal
• Slowly increase pressure. If there is flow with
no command input, it may be necessary to
NULL the valve. Refer to the Troubleshooting
section.
• Decrease pressure and connect command.
For initial setup, the external closed loop gain
should be minimum and the pressure at a low
setting.
• Once the system is operational, increase the
systemgainandincreasethesystempressure.

Symptom Cause Solution
Instability Power Supply? Select a power supply not current limited below 4.0 A Use a
separate power supply for each valve. The power supply must
be chassis grounded.
Noise on inputs? To verify, remove input signals and short + CMD to - CMD. For
best noise immunity, connect input signals (2 wires for each
input) directly to the command source. This is a 100 Hz valve so
60 hertz noise at the inputs will be amplified.
System Gain? Initial startup should be with the external feedback loop gain at a
minimum value and lower pressure. Oscillation maybe a result of
high loop gain. (Note: With motion controllers minimum gain may
be lower than one).
OilTemperature? The oil temperature should be within the 100° F to 140° F range.
(Viscosity range = 75 to 300 SSU).
Air in valve? High frequency operation with low tank line pressure could result
in air in the valve. The suggested tank line pressure is for > 25
PSI. To eliminate air, apply a low pressure and cycle the valve at
a low frequency with a command of approximately. ± 10 VDC (or
± 20 mA)
Valve Gain? Adjust potentiometer P6 CCW to decrease valve gain.
Null System Variations? The valve was nulled for a double rod cylinder. If excessive drift
occurs with no inputs connected, null the valve for minimum flow
or movement by slowly adjusting potentiometer P2. This should
require less than ± 3 turns from the set value.
Low Flow Flow Limited? Verify potentiometer P1 is fully CW. Verify command input is 10
VDC for maximum flow.
FloatingInput? Connect the unused CMD input to source common.
System Pressure? Verify that the system pressure is set as required and there are
no other flow paths.
No Flow Power? Verify there is power to the board and it is wired with the correct
polarity.
Verify that the ENABLE signal is present.
Verify that the connections to the valve subplate are correct.
Full Flow Phasing? If connected to an external feedback system, verify open loop
operation of valve with a potentiometer. Improper system
phasing would result in maximum Command input.
CylinderExtended/ Phasing? System phasing is incorrect. Try reversing the system CMD or
Retracted and Fdbk inputs.
Won't Return
Flow With No Enable System Dynamics? The spool will return to the fourth position only if the system dy-
namic flows and pressures are within the power capacity
envelop. The fourth position is subject to all Bernoulli flow forces,
radial hydraulic lock forces and other forces that affect all
directional control valves. The system designer must determine if
the dynamic flows and pressures in the system will prevent the
spool from returning to the fourth position. This would have to be
verified with full load testing.
As with any spool valve, the user should not rely on the valve to
hold loads in place. The leakage rate through the fourth position
blocked center spool (80 spool) will allow an unloaded single rod
cylinder to extend. This occurs with any blocked center four-way
valve.

For maximum valve reliability, adhere to the
following Installation Information.
Fluid Recommendations
Premium quality hydraulic oil with a viscosity
range between 150 - 250 SSU (32-54 cst.) at 38° C
(100°F)is recommended.The absolute operation
viscosity range is from 15 - 300 (15 - 44 cst.) Oil
should have maximum anti-wear properties and
rust and oxidation treatment.
Filtration
For maximum valve and system component life,
the system should be protected from contamina-
tion at a level not to exceed 125 particles greater
than 10 microns per milliliter of fluid. (SAE Class
4orbetter/ISOCode16/13).Flushingthesystem
prior to valve installation is recommended on new
installations.
Silting
Silting can cause any sliding spool valve to stick,
andnotspringreturn,ifheldshiftedunserpressure
for long periods of time. The valve should be
cycled periodically to prevent sticking.
Special Installations
Consult your Parker representative for any appli-
cation requiring the following:
• Pressure above rated
• Fluid other than those specified
• Synthetic or fire-resistant fluids
• Oil temperature above 60°C
• Flow path other than normal
• Non-standard power supply grounding
Torque Specifications
The recommended torque values for the bolts
whichmountthevalve to the manifold or subplate
are as follows:
NFPA Size Bolt Thread Torque
Size
D03 M5 x 0.8 5.6 Nm
Mounting Restriction
In order to ensure proper operation, the D1FH
must be mounted horizontally. If the valve is
mountedvertically,a check valve with a minimum
rating of 1.4 bar (20 PSI), should be placed in the
tank line to maintain back pressure to the valve.
Tank Line Surges
If several valves are piped with a comman tank
line, flow surges in the line may cause an
unexepted spool shift. Separate tank lines should
be used when line surges are expected.
