ABSTRACT:
A valve for use in regulating the flow of fluid between a first fluid side and a second fluid side of a hydraulic circuit. A bore is extended through a valve seat, and the bore and valve stem cooperate to form a fluid passage from the first side to the second side. A plurality of ribs are located on one side of the valve seat and extend in a direction generally parallel to the bore.
