ABSTRACT:
An inline check valve housing, having a valve seat adjacent its inlet end normal to the axis of its fluid passageway, is provided with a plurality of webs projecting inwardly of its inner wall surface defining a guide for axial movement of a poppet valve having a polygonal-shaped shank toward and away from the housing valve seat. The webs each have an inwardly projecting lug at its end portion opposite the valve seat for engaging recessed spaced opposing circumferential edge portions of a valve shank guide cooperatively surrounding the poppet valve shank for preventing angular rotation of the shank guide and poppet valve relative to the housing.
