1. A hydraulic valve arrangement comprising:
a system chamber including a manifold and a poppet,
the manifold including a manifold body defining a first port and a second port leading to a bore, the manifold body defining a bleed surface that is a single/one-piece unitary integral uniform material construction with the manifold body throughout an entire body of the bleed surface as the bleed surface extends from the manifold body, the manifold defining a bleed ring that surrounds the bore and has an angled contact surface that extends between the bleed surface and the bore, the manifold body also defining an annular recess around the bleed ring that is recessed relative to the bleed surface, the annular recess having an inner radius that is radially spaced outwardly from the bore a first distance and having an outer radius that is radially spaced outwardly from the bore a second distance that is greater than the first distance, andthe poppet being slidably disposed within the bore between a plurality of positions, the poppet being structured to close a main flow path between the first and second ports when the poppet is in a first position and the poppet being structured to at least partially open the main flow path when the poppet slides away from the first position, the poppet defining an angled contact surface that is configured to engage the angled surface of the bleed ring when the poppet is in the first position;the bleed ring being sufficiently low so that a portion of the poppet extends into the bore beyond the annular recess when the poppet is in the first position. |
