Hydraulic System 121
Proportional Valve
AUTOMIZER™ vehicles are equipped with a proportional valve (see Figure 5-3), as part of the arm vane
pump, that powers all arm functions (gripper [open/close], lifting arm [extend/retract, up/down],
chute [left/right], crusher panel [up/down], etc.) and other options.
As such, the amount of flow coming out of it will be according to the position of the spool. This
feature, called proportional control, allows infinite control of the speed and movement of the arm.
Each section of this valve is actuated by an electric coil located under the valve.
