ABSTRACT:
A hydraulic stack valve assembly for controlling the pressure and flow of hydraulic fluid in a hydraulic system. The stack valve assembly includes a valve body including flow control valves and a valve cover including pressure control valves and a flow director plate sandwiched between the flow control and the pressure control valves for directing modulated and regulated pressurized fluid through the flow control valves to hydraulic actuators in the hydraulic system. The stack valve has the provision of interchanging the flow director plate to modify the valve assembly and adapting the valve for use of the desired number of flow control valves and the pressure control valves best suited to the hydraulic system in which the valve assembly is used.
