ABSTRACT:
A hydraulic valve assembly which can be used for controlling a motor or the like includes a first directional control member which selectively allows hydraulic fluid to flow from an associated hydraulic pump through a hydraulic fluid circuit to an associated reservoir and to an associated hydraulic motor. A second directional control member is connected to the fluid circuit for selectively allowing hydraulic fluid to flow directly to the associated reservoir as directed by the first member. A third directional control member is connected to the fluid circuit for selectively allowing hydraulic fluid to flow directly to the associated hydraulic motor as directed by the first member. A relief member is operatively connected with the fluid circuit for allowing hydraulic fluid to be relieved from the assembly to the associated reservoir.
