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).
