ISO 4401-03-02-0-05
(CETOP 4.2-4-03-350)
Solenoid actuated directional control valve, direct
operated with mounting surface according to ISO
4401-03 standards.
— The valve is supplied with 3 or 4 ways design, 2 or 3
positions, with a wide range of spools.
— The valve body is made with high strength iron castings
provided with wide internal paths in order to minimize
the flow pressure drop. Wet armature solenoids with
interchangeable coils are used (for further
information on solenoids see par. 7).
— The valve is available with DC solenoids.
— The valve is also available with zinc-nickel
coating that ensures a salt spray resistance up to
120 hours.

2 - HYDRAULIC FLUIDS
Use mineral oil-based hydraulic fluids HL or HM type, according to ISO 6743-4. For these fluids, use NBR seals (code N). For fluids HFDR type
(phosphate esters) use FPM seals (code V). For the use of other fluid types such as HFA, HFB, HFC, please consult our technical department.
Using fluids at temperatures higher than 80 °C causes a faster degradation of the fluid and of the seals characteristics. The fluid must be
preserved in its physical and chemical characteristics.

6 - OPERATING LIMITS
The curves define the flow rate operating fields according to the valve pressure of the different versions. The values have been obtained
according to ISO 6403 norm with solenoids at rated temperature and supplied with voltage equal to 90% of the nominal voltage. The value
have been obtained with mineral oil, viscosity 36 cSt, temperature 50 °C and filtration according to ISO 4406:1999 class 18/16/13.
The limits have been verified with standard 4-way valve. Performance can be considerably reduced if a 4-way valve is used as 3-way, with port
A or B plugged or without flow.

7 - ELECTRICAL FEATURES
7.1 - Solenoids
These are essentially made up of two parts: tube and coil. The tube
is threaded into the valve body and includes the armature that
moves immersed in oil, without wear. The inner part, in contact with
the oil in the return line, ensures heat dissipation. The coil is
fastened to the tube by a threaded ring, and can be rotated 360°, to
suit the available space.

Protection from atmospheric agents IEC 60529
The IP protection degree is guaranteed only with both valve and
connectors of an equivalent IP degree, correctly connected and
installed.
NOTE: In order to further reduce the emissions, with DC supply,
use of type H connectors is recommended. These prevent voltage
peaks on opening of the coil supply electrical circuit
(see cat. 49 000).

9 - INSTALLATION
Configurations with centering and return springs can be mounted in any position; type RK valves -
without springs and with mechanical detent - must be mounted with the longitudinal axis horizontal.
Valve fixing takes place by means of screws or tie rods, with the valve mounted on a lapped surface,
with values of planarity and smoothness that are equal to or better than those indicated in the drawing.
If the minimum values of planarity and/or smoothness are not met, fluid leakages between valve and
mounting surface can easily occur.
