WARNING: Electromagnetic Compatibility (EMC)
It is necessary to ensure that the unit is wired up in accordance with the connection arrangements shown above. For
effective protection the user’s electrical cabinet, the valve subplate or manifold and the cable screens should be
connected to efficient ground points.
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.

Max. Flow Rates
Based on warm solenoid(s) operating at
10% below rated voltage.
Flow limits applicable to following
usages:
1. All valves except those with types 22,
52, 56, 521 and 561 spools having
simultaneous equal flow rates from P
to A or B and from B or A to T.
2. Valves with type 22 spools having
flow from P to A or B, the other being
blocked. T is drained at all times.
3. Valves with types 52, 56, 521 and
561 spools having one service port
connected to the full bore end of a
2:1 area ratio double-acting cylinder
and the other service port to the
annulus end.
4. Valves with type 23 spools having
single flow from A or B to T, P and the
other service port being blocked.
Consult Vickers with application details if
any of the following are required:
a) Single flow path, i.e. P to A, P to B,
A to T or B to T.
b) Substantially different simultaneous
flow rates between P to A or B and
B or A to T.
c) Spools as in 3 above are to be used
with cylinder ratios greater than about
3:1 at low flow rates or 2:1 at high
flow rates.

Response Times, Typical
Time taken from when signal is first
applied at the solenoid until the spool
completes its travel. Based on
DG4V-5-2C at 60 L/min (16 USgpm)
from P to A to B to T and at 160 bar
(2320 psi) with petroleum oil at 36 cSt
(168 SUS) and at 50_C (122_F):
AC energizing 30 ms. . . . . . . . . . . . . . . . .
AC de-energizing 40 ms. . . . . . . . . . . . . .
DC energizing 120 msY. . . . . . . . . . . . . .
DC de-energizing 45 msY:. . . . . . . . . .
: In pure switched conditions, devoid of the
efffects of any suppression diodes and
full-wave rectifiers.
Y DG4V-5-2CJ valves. Longer response
times can be obtained by fitting an orifice
plug in a special pilot port, standard in all
bodies. An orifice kit 459065, containing a
selection of plugs of differing orifice size,
can be ordered separately. Ask your
Vickers representative for details.
Hydraulic Fluids
Water glycols can be used with
F13-prefix DC-voltage models or with
non-prefix AC-voltage models.
Non-prefix DC-voltage models and all
AC-voltage models can be used with
anti-wear hydraulic oils, water-in-oil
emulsions, phosphate esters (not alkyl
based).
The extreme operating viscosity range is
from 500 to 13 cSt (2300 to 70 SUS) but
the recommended running range is 54 to
13 cSt (245 to 70 SUS).
For further information about fluids see
catalog 920.

For synthetic fluids consult manufacturer
or Vickers where limits are outside those
for petroleum oil.

ensure that viscosities stay within the

control methods and the selection of
products to control fluid condition are
included in Vickers publication 9132 or
561, “Vickers Guide to Systemic
Contamination Control”. The book also
includes information on the Vickers
concept of “ProActive Maintenance”.
The following recommendations are
based on ISO cleanliness levels at
2 mm, 5 mm and 15 mm. For products in
this catalog the recommended levels
are:
