SOLENOID VALVE (LEVER LOCK)
3K6AX00
SOLENOID VALVE (LEVER LOCK)
This valve switches circuit connections by moving the
spool using magnets and supplies the pilot pressure to
the pilot valve and 2nd-speed travel switch.
The pilot pressure is kept constant with the relief valve.
Solenoid switching and relief function
For simplification purposes, only port A will be used in
the descriptions below as port A and port B in the valve
operate in the same way.
When the solenoid is not energized:
The pressure oil from port P is blocked from entering the
circuit to port A by the spool (5) and plunger (10).
The oil flows through the port A (on the pilot circuit side
of the pilot valve or 2nd-speed travel switch) 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.
In addition, the pressure in port C is the same as that in
port P under normal conditions as port C is connected to
port P.
When the pressure of port P increases and exceeds the
set value for the spring (11), the plunger (10) is pushed
upward, and the oil from port P flows into port T from the
“a” section.
When the pressure of the port P drops and falls below a
set value for the spring (11), the plunger (10) is moved
down by the spring (11), which blocks the circuit to the
port P and port T.
This enables the pressure inside the circuit to be main-
tained at a constant level.
When the solenoid is energized:
A magnetic field is generated around the coil that causes
the push rod to be pulled downward and the spool (5) to
be pushed down. This causes the oil in the port P to flow
to the port A, and the pressure is transmitted to the lower
pilot circuit.
When the power to the coil is turned OFF, the spool (5) is
pushed upward by the spring (4).
