Abstract
A hydraulic valve arrangement includes a manifold and a poppet. The manifold defines a bleed ring that surrounds a bore and has an angled surface. The manifold also defines an annular recess around the bleed ring that provides a relief region. The poppet is slidably disposed within the bore and is 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 defines an angled contact surface that is configured to engage the angled contact surface of the bleed ring when the poppet is in the first position.
