ABSTRACT:
A check valve or relief valve is provided with a floating shroud having a retaining lip engaging with a downstream edge of a moving poppet to maintain the shroud and a captured seal ring in proximate relationship with the poppet to maximize the usefulness of the flow ports in the poppet and to eliminate seal ring flutter. The retaining lip of the shroud may have axially directed holes to create a reduction in pressure between the seal ring and the poppet seat to move the seal ring against the poppet seat during high flow conditions.
