HYDRAULIC UNITSCONTROL VALVE (HIGH FLOW)
OPERATION
When the solenoid (2) of the control valve (high
flow) (1) is powered on, the pilot pressure from the
pilot valve (3) operates the spool of the auxiliary hy-
draulic section of the control valve (4) to let the hy-
draulic oil from the pump P3 flow into the auxiliary
hydraulic (A). The pilot pressure is led to the port
PL of the control valve (high flow) (1) to operate the
spool of the switching valve (5) and to let the hy-
draulic oil from the pump PTO flow to the auxiliary
hydraulics (A). This will combine the hydraulic oil
flows from the pump P3 and the pump PTO together.
Also, the unload valve (6) of the control valve (high
flow) (1) keeps the pressure from the pump PTO
constant.
When the solenoid (2) is not powered on, the hy-
draulic oil from the pump PTO flows through the
unload valve (6) into the tank.
Switching Valve
When the Spool is in the Neutral Position:
When the spool of the control valve is not moved,
the hydraulic oil supplied from the port P flows
through the center bypass passage (C) and port P,
and returns to the tank.
When the Spool is Operating:
When the pilot pressure is led to the port PL, the
spool moves to the right to close the center bypass
passage. Then the hydraulic oil flows from the pas-
sage (D) into the port A.
