This wet armature solenoid operated directional
control valve is for directing and stopping flow at any
point in a hydraulic system. Its primary function is to
determine the direction of the fluid flow in a work
cylinder or determine the direction of rotation of
a fluid motor.
These valves are designed to meet the requirements
of high performance, precision industrial hydraulic
systems operating at pressures up to 315 bar (4570
psi) and flows to 115 L/min (30 USgpm). They mount
on the ISO size 05 mounting surface.
The performance of the most conventional solenoid
operated directional valves is limited by the flow
forces acting on the spool in opposition to the
solenoids and return springs. Special attention
is given to compensating for, or minimizing,
these undesirable forces in the design of the
series 5 valve.
Introduction
Features and benefits
High performance
High pressure and flow capability with performance comparable to
competitors, due to 315 bar (4570 psi) and 115 L/min (30 USgpm)
ratings.
Reliability
A high margin of shifting force is available to overcome spool friction
due to dirt and other contaminants. Also, a balance spool with
cushioned shift means less wear and long life.
• Wet armature solenoids for quieter operation and long life with no
dynamic seal leakage.
• Molded coil construction is impervious to moisture and dirt.
• Larger diameter spool combined with constant area and tangential
flow passages result in low pressure drop.
• Stainless steel solenoid pin is processed hardened for long life.
• Patented detent mechanism for greater reliability and long life.
Serviceability
Plug-in coils and electrical connections simplify maintenance.
• Cartridge style manual actuators; easily replaced or exchanged for
an SAE plug.
• Plug–in solenoid coil for ease of servicing can be replaced without
disturbing the hydraulic system or wiring cavity.
• Two solenoid sizes to choose from for optimum performance and
cost selection.
• Optional pin-type or top-side plug-in electrical connectors for easy
valve replacement. Reversible to fit any installation need.
• Dual frequency (50/60 Hz) 2-wire coils for lower inventory at the
OEM (optional).

DG4V4-01, 1* Design
Optimum performance features
Equalizes hydraulic force on ends of the spool and cushions
spool shift.
When spool is shifted, the fluid displaced from one end of the
spool is transferred to the other end through this passage which is
designed to provide a cushioning effect and balance the spool.
Spool land sequencing
Accurate sequencing of land opening and closing provides maximum
axial stability.
In the example above, it is important that the flow path A to T is
opened before the path P to B to prevent pressure intensification
which could upset axial balance and limit valve function.
Isolated solenoid chambers
Transient pressure peaks in the solenoid to prevent solenoid tube
failure are minimized.
Pressure surges can occur within the armature tube of 2-land wet
armature valves due to cylinder port decompression. These surges
can easily exceed tube pressure rating and result in premature
tube failure.
The armature tube area is isolated from the tank port area by the
outboard lands on the 4-land spool. Tank port pressure surges do not
reach the armature tube to cause failure.
Spool force-balancing contour
The hydraulic unbalancing effects of fluid momentum between the
cylinder and tank ports is minimized.
Flow forces that are developed at the conventional square land
orifice (P to B) are partially compensated for by the force balancing
contour on the outer spool lands (A to T).

Solenoid energizing
Spring centered and spring offset valves will be spring positioned
unless the solenoid is energized continuously. No-spring detented
valves may be energized momentarily, approximately 0.15 second;
when the solenoid is de-energized the spool will remain in the last
position attained, provided there is no shock, vibration or unusual
pressure transients.
!
CAUTION
Any sliding spool valve, if held shifted under pressure for long
periods, may stick and not return, due to silting. Therefore, it is
recommended that the valve be cycled periodically to prevent this
from occurring.
Response Time
The following response times were measured from the point of
energization/ de-energization to the point of first indication of inlet
pressure change. Response up to full system pressure is
dependent on the system’s compressed volume and can vary
with each application.

Specifications
Valve function, symbol and recommended maximum flow
(See page 7 for maximum flow curves).
Maximum flow data
Maximum recommended flow
data is for AC or DC solenoids
at 90% nominal voltage in a
4-way circuit with cylinder ports
either looped or blocked and
containing 2,5 liter (0.66 USgpm)
compressed volume. Reduced
performance may result when
certain spools are used in
3-way circuits.
Fluids and seals
Buna N seals are standard and
are compatible with water-in-
oil emulsions, high water base
fluids and petroleum oils. For
phosphate ester fire resistant
fluids, Viton® seals must be
specified. Seals for water
glycol have an F6 designation.
Maximum operating pressure
for high water base fluids is
1000 psi.

Pressure drop
Pressure drops in offset positions except where otherwise
indicated
For other viscosities, pressure drops approximate to:
A change to another specific gravity will yield an approximately
proportional change in pressure drop.
The specific gravity of a fluid may be obtained from its producer. Fire
resistant fluids usually have higher specific gravities than oil.
Drain
On 2-way valves, ‘‘T’’ is the drain and must be connected to the tank
through a surge-free line, so there will be no back pressure at
this port.

CAUTION
Surges of oil in a common line serving these and other valves can
be of sufficient magnitude to cause inadvertent shifting of these
valves. This is particularly critical in the no-spring detented type
valves. Separate tank lines, or a vented manifold with a continuous
downward path to tank are necessary. Consult your Vickers
representative for instructions.

Fluid cleanliness
Essential information on the correct methods for treating hydraulic
fluid is included in Vickers publication 561 “Vickers Guide to
Systemic Contamination Control” available from your local Vickers
distributor or by contacting Vickers, Incorporated. Recommendations
on filtration and the selection of products to control fluid condition
are included in 561.
Recommended cleanliness levels, using petroleum oil under
common conditions, are based on the highest fluid pressure levels
in the system. Fluids other than petroleum, severe service cycles, or
temperature extremes are cause for adjustment of these cleanliness
codes. See Vickers publication 561 for exact details.
