When energised, this 3/2 switching valve provides a path, which
allows pilot (control) pressure supply to the proportional solenoids
Y2301 & Y2302.
The proportional valve controls dynamic braking to the right by
controlling the volume of oil from the slew motor return ports that is
discharged to the tank line. With maximum current the valve is fully
open. By pressing the brake pedal/or via closed loop lever control
ECOS reduces the current for proportional closing of the valve, thus
providing dynamic braking.
