ABSTRACT:
An automatic, hydraulically actuated, sequencing valve for use with a pair of hydraulic actuators (e.g. double acting hydraulic cylinders). The valve includes a valve body, a bore therein, and a valve spool axially shiftable in the bore. The valve spool shifts automatically due to creation of a differential in hydraulic pressures on opposite ends of the valve spool during each admission of hydraulic fluid under actuating pressure to the valve.
