A valve is disclosed and can include a valve body having a central bore for passage of fluid there through and a longitudinal axis. The valve can also include a seal installed within the valve body along the central bore. The seal can include a first seal member having an annular ring portion and a hub portion extending from the annular ring portion. The seal can also include a second seal member including an annular ring configured to engage a distal end of the hub portion and create a sealing engagement between the hub portion and the annular ring when a compressive force is applied to the first and the second seal members.

1. A valve, comprising: a valve body defining a central bore for passage of fluid there through, the central bore having a longitudinal axis;a groove in the valve body near an end surface of the valve body;a rigid seal installed within the valve body, the rigid seal comprising: a first rigid seal member comprising an annular ring portion and a hub portion extending from the annular ring portion; anda second rigid seal member including an annular ring configured to engage the hub portion and create a sealing engagement between the hub portion and the annular ring when a compressive force is applied to the first and the second seal members by at least one pipe coupled to the valve, the annular ring of the second rigid seal member including a protrusion extending outwardly from the annular ring, the protrusion configured to engage the groove in the valve body. 2. The valve of claim 1, wherein the first seal member comprises an inner annular surface defining the central bore. 3. The valve of claim 2, wherein the inner annular surface of the first seal member defines the entire surface of the central bore. 4. The valve of claim 1, wherein the sealing engagement between the hub portion of the first seal member and the annular ring portion of the second seal member defines a seal interface that is spaced at a distance from a central axis along the longitudinal axis of the central bore. 5. The valve of claim 4, wherein the sealing engagement is spaced at a radial distance from an inner annular surface of the first seal member defining the central bore. 6. The valve of claim 5, wherein the second seal member is radially spaced apart from the inner annular surface defining the central bore. 7. The valve of claim 5, wherein the second seal member is displaced from a fluid flow pathway within the central bore. 8. The valve of claim 1, wherein the second seal member comprises an annular shape having an inner surface defining a central opening. 9. The valve of claim 8, wherein the inner surface of the second seal engages an interior surface of the first seal member, and wherein the inner surface of the second seal is spaced apart from the central bore. 10. The valve of claim 1, wherein the second seal member has a U-shaped cross-sectional contour. 11. The valve of claim 1, wherein the second seal member is mechanically fastened to the valve body. 12. The valve of claim 11, wherein the second seal member is fastened to the valve body via a clip. 13. The valve of claim 1, wherein the sealing engagement is a sealing structure comprising a tongue and groove structure. 14. The valve of claim 1, wherein the sealing engagement includes a complementary engagement structure includes at least one of a rectangular-shaped structure, a wedge-shaped structure, a K-shaped structure, or a combination thereof. 15. The valve of claim 14, wherein the first seal member is configured to snap into the second seal member. 16. The valve of claim 1, wherein a surface of the second seal member defines a portion of an exterior surface of the valve body that is spaced apart from the central bore. 17. The valve of claim 1, wherein the first seal member comprises a first radial bore extending transversely through the first seal member perpendicular to a longitudinal axis extending along the central bore. 18. The valve of claim 17, wherein the first seal member comprises a second radial bore extending transversely through the first seal member perpendicular to the longitudinal axis extending along the central bore. 19. The valve of claim 1, further comprising a disc installed perpendicularly within the seal, wherein the disc is movable between a first position in which fluid communication through the seal is blocked and a second position in which fluid communication through the seal is permitted. 20. The valve of claim 19, further comprising an actuator rod extending through the valve body and into the seal wherein the actuator rod is coupled to the disc and wherein the actuator rod is rotatable to rotate the disc within the seal. 21. The valve of claim 1, wherein the seal comprises a generally rigid, corrosion resistant material. 22. The valve of claim 21, wherein the generally rigid, corrosion resistant material comprises a fluoropolymer. 23. The valve of claim 22, wherein the fluoropolymer comprises fluorinated ethylene propylene (FEP), ethylene-tretrafluoroethylene (ETFE), poly tetrafluoroethylene-perfluoropropylvinylether (PTFE-PPVE), poly tetrafluoroethylene-perfluoromethylvinylether (MFA), polytetrafluoroethylene (PTFE), polyvinylidene fluoride (PVDF), ethylene chlorotrifluoroethylene (ECTFE), polychlorotrifluoroethylene (PCTFE), tetrafluoroethylene-hexafluoropropylene-vinylidene fluoride (THV), or a combination thereof. 24. The valve of claim 21, wherein the second seal member consists essentially of polytetrafluoroethylene-perfluoropropylvinylether (PTFE-PPVE).
