Fig. 6-26: Selector Valve – Models with Mid-Inlet Hydraulics
The 6-port circuit selector valve (directional control valve) is located on the
valve plate near the center of the machine. It directs fluid to the control
valve when the joystick is activated. The 6-port selector valve directs the
flow of hydraulic oil from the joystick controller to the appropriate control
valve section. The solenoids are used to change the flow of oil from one
control valve section to the other.
