SWING PRIORITY VALVE
OPERATION
Swing at neutral
• When the swing is at neutral, no pilot pressure oil flows from the solenoid valve. The swing priority valve is not actuated, so the pressurized oil from the front main pump passes through port P1 and flows to the arm-Lo control valve.
When operating swing
When the swing is operated, the limit switch on the linkage is actuated. This actuates the solenoid valve, and pilot pressure acts on port PB4 of the swing priority valve, and pushes the spool to the left.
When this happens, the pressurized oil flowing from the front main pump to the arm low control valve is restricted by the swing priority valve. The arm speed is controlled,· so simultaneous operations are made easier.
