ABSTRACT:
A valve for controlling the flow of hydraulic fluid from a hydraulic pump to and back from a pair of hydraulic motors. The valve includes a selector spool for selectively energizing and de-energizing the motors. A pair of flow dividers each include a pair of flow divider spools which are slidingly longitudinally arranged. A pair of poppets, also longitudinally slidingly arranged, are located between the spools are selectively shifted in response to the hydraulic fluid flow and pressures within the motors. The spools and poppets longitudinally shift to equalize the pressure of the hydraulic fluid delivered to each motor and minimize loses. An override spool is selectively shiftable for bypassing the flow dividers and directly connecting the pump to the motors.
