CD.3.*.E... DIRECTIONAL CONTROL
STACKABLE
VALVE WITH
D15 COILS
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 IP66 in accordance with
DIN 40050 standards, are available in direct current form and different voltage. The electrical
supply connectors meet DIN 43650 ISO 4400 standards; AMP Junior, AMP Junior and
integrated diode, flying leads, Deutsch DT 04 - 2P coil type, connectors are also available with

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 3 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.
