SOLENOID VALVE(3RD AUXILIARY LINE PIPING)
This valve switches circuit connections by moving the
spool using magnets and supplies the pilot pressure to
the 3rd auxiliary section.
Solenoid valve
When the solenoid is not energized:
The oil in the port P (pump side) is blocked by the spool
(1).
The oil ļ¬ows through the port A (on the pilot circuit side
of the 3rd auxiliary section) and port T
(on the tank side), which means that the pressure of the
downstream pilot circuit is the same as the tank pres-
sure.
When the solenoid is energized:
A magnetic ļ¬eld is generated around the coil that causes
the push rod to be pulled downward and the spool (1) to
be pushed down. This causes the oil in the port P to ļ¬ow
to the port A, and the pressure is transmitted to the lower
pilot circuit.
