ABSTRACT:
A check valve (10) including a valve disk (12), wherein the valve disk (12) is so arranged and configured as to be of a thickness sufficiently substantial to prevent the valve disk (12) from exhibiting a significant amount of flexure even under high reverse pressure, an upper housing portion (16) having an inlet aperture (18) formed therein, a lower housing portion (20) having an outlet portion (22) formed therein, the upper housing portion (16) being formed with a valve seat (24) which protrudes towards the lower housing portion (20) by a preselected distance, the inlet aperture (18) extending through the valve seat (24), a static seal ring (26) for installation between the upper (16) and lower (20) housing portions in sealing fashion, the static seal ring (26) being located circumferentially around and spaced away from the valve disk (12), and a support web (32) extending between the static seal ring (26) and the valve disk (12) for supporting the valve disk (12) from the static seal ring (26), the support web (32) being flat when in an unbiased position, the support web (32) being elastomeric and functioning to bias and maintain the valve disk (12) against the valve seat (24) of the upper housing portion (16) around the inlet aperture (18) in sealing fashion until and unless a predetermined forward pressure drop exists across the valve (10), the support web (32) having disposed therein a plurality of apertures (36) to allow the passage of a fluid therethrough.
