Operation
•
When the swing is operated, the pilot pressure oil
from the travel shuttle valve pushes spool (1) of
the swing priority valve to the left.
•
As a result, the pressure oil flowing from the front
main pump through port PR to the arm Lo control
valve is throttled, and the arm speed is restricted
to improve the simultaneous operation perform-
ance.
