ORDERING CODE
For series connection
configuration, a special
individual stackable valve
CDC.3.*.E.04.**.3T.2 (A B or G
parallel body type only, with
spool 04 type, 3T variant) must
always be used as first element.
For other individual stackable valve
must use body D E or H connector
series type with spool 04 only.

Directional control stackable valve body is available in two different sizes:
G3/8" or 9/16-18UNF (SAE 6).
The operation of the directional valve is electrical. The centring is achieved by means of
calibrated length springs which immediately reposition the spool in the neutral position when
the electrical signal is shut off. To improve the valve performance, different springs are used
for each spool.
The solenoids, constructed with a protection class of IP65 in accordance with BS 5490
standards, are available in direct current form and different voltage. The electrical controls are
equipped with an emergency manual control inserted in the tube.
The electrical supply connectors meet DIN 43650 ISO 4400 standards. On request, could be
available the following coil connec-
tion variants: AMP Junior connec-
tions; flying leads connections, with
or without integrated diode; Deutsch
connections with bidirectional inte-
grated diode.
The body valve is white zinc plated.
TAB.4 - A09 - DC VOLTAGE
The AMP Junior coil and with the flying
leads (with or without diode) coils are avail-
able in 12V or 24V DC voltage only.
• The Deutsch coil with bidirectional diode
is available in 12V DC voltage only.

(**) It's suggest to order the variant without connectors. The
connectors must be order separately. See Ch. XI Page 25

PRESSURE DROPS
DIRECTIONAL CONTROL STACKABLE VALVE
The diagram at the side shows
the pressure drop curves for
spools during normal usage.
The fluid used is a mineral oil with
a viscosity of 46 mm
2
/s at 40 C°;
the tests have been carried out at
a fluid temperature of 40 C°.
LIMITS OF USE (MOUNTING C-E-F)
The tests have been carried out with solenoids at operating temperature
and a voltage 10% less than rated voltage with a fluid temperature of 50
C°. The fluid used was a mineral oil with a viscosity of 46 mm
2
/s at 40
degrees C. The values in the diagram refer to tests carried out with the
oil flow in two directions simultaneously (e.g. from P to A and at the same
time B to T).
In the cases where valves 4/2 and 4/3 are used with the flow in one
direction only, the limits of use could have variations which may
even be negative (See curve No 4 and Spool No 16 used as 2 or 3
ways). The tests were carried out with a counter-pressure of 2 bar
at T port.
