Abstract

The present invention privilege order described herein intends to solve the still ongoing technical problems, by proposing a hydraulic directional control. The hydraulic directional control proposed herein provides, besides the already existing items, one pilot pressure sequence valve, one pressure vent valve with gauged vent for flux control, and one externally piloted stop valve.
