A valve for a hydraulic system is provided including a work port channel, a load sense channel, and a tank channel. Additionally, a body cavity extends between the work port channel and the tank channel, and a spool is movably positioned in the body cavity. The body cavity defines an inner surface and the spool defines an outer surface. The inner surface of the body cavity and the outer surface of the spool together define a interface between the body cavity and the spool that extends outwardly from a longitudinal axis, such that an increased pressure differential between the work port channel and a load sense channel increases a sealing force, allowing for a more responsive valve in the hydraulic system with less leakage.
