™ vehicles are also equipped with an arm control valve (see Figure 5-4). As part of the
arm
vane pump, this valve powers all arm functions (gripper open/close, arm extend/retract, and arm up/
down).
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 behind the valve.
