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.

A valve (100), comprising: a valve body (102) defining a first central bore (104) for passage of fluid there through, the central bore (104) having a longitudinal axis, the valve body (102) also defining a second central bore (132) perpendicular to the first central bore (104) along a central axi
1. A valve (100), comprising: a valve body (102) defining a first central bore (104) for passage of fluid there through, the central bore (104) having a longitudinal axis, the valve body (102) also defining a second central bore (132) perpendicular to the first central bore (104) along a central axis (124), wherein the second central bore (132) is configured to receive an actuator rod (134);a rigid seal (150) installed within the valve body (102) along the first central bore (104), wherein the seal (150) comprises: a first seal member (152) comprising an annular ring portion (156) and a hub portion (158) extending from the annular ring portion (156), wherein the hub portion (158) includes a first radial bore (170) and a second radial bore (172) aligned with the second central bore (132) along the central axis (124); anda second seal member (154) including an annular ring configured to engage a distal end (160) of the hub portion (158) and create a sealing engagement between the hub portion (158) of the first seal member and the annular ring of the second seal member by a complementary engagement structure wherein one seal member extends into the other seal member when a compressive force is applied to the first (152) and the second seal members (154), wherein the sealing engagement occurs at a seal interface (180) and the entire seal interface (180) is spaced a distance, D, from the central axis (124). 2. The valve (100) of claim 1, wherein the annular ring portion (156) of the first seal member (152) includes an outer diameter, ODR, wherein the hub portion (158) of the first seal member (152) includes an outer diameter, ODH, and wherein ODR is greater than ODH. 3. The valve (100) of claim 1, further comprising a disc (140) installed perpendicularly within the seal, wherein the disc (140) is movable between a first position in which fluid communication through the seal (150) is blocked and a second position in which fluid communication through the seal (150) is permitted. 4. The valve (100) of claim 3, further comprising an actuator rod (134) extending through the valve body (102) and into the seal (150) wherein the actuator rod (134) is coupled to the disc (140) and wherein the actuator rod (134) is rotatable to rotate the disc (140) within the seal (150). 5. The valve (100) of claim 1, wherein the complementary engagement structure includes a tongue and groove structure. 6. The valve (100) of claim 5, wherein the complementary engagement structure is rectangular, wedge-shaped, K-shaped, or a combination thereof. 7. The valve (100) of claim 1, wherein the complementary engagement structure includes a groove and a generally curved flange. 8. The valve (100) of claim 7, wherein the groove is configured to deform the flange. 9. The valve (100) of claim 1, wherein the complementary engagement structure includes a flared tube and a flared sleeve, wherein the flared tube fits around the flared sleeve. 10. The valve (100) of claim 1, wherein the second seal member (154) includes a pocket formed therein and wherein the hub portion (158) of the first seal member (152) is configured to fit into the pocket. 11. A seal assembly, the seal assembly comprising: a first rigid seal member (152) having an annular ring portion (156) and a hub portion (158) , wherein the hub portion (158) includes a first radial bore (170) and a second radial bore (172) formed along a central axis (124); anda second rigid seal member (154) include an annular ring, wherein the first seal member (152) and the second seal member (154) include a complementary engagement structure wherein one seal member extends into the other seal member configured to create a seal interface (180) within a valve (100) in which the seal assembly is installed, wherein the entire seal interface (180) is spaced a distance, D, from the central axis (124); and,wherein the seal assembly is adapted to be disposed in a valve body (102) defining a first central bore (104) for passage of fluid there through, the central bore (104) having a longitudinal axis˜the valve body (102) also defining a second central bore (132) perpendicular to the first central bore (104) along the central axis (124), wherein the second central bore (132) is configured to receive an actuator rod (134). 12. The seal assembly of claim 11, wherein the complementary engagement structure is configured to provide the sealing interface (180) when the seal assembly is compressed along a longitudinal axis. 13. The seal assembly of claim 11, wherein the seal (150) comprises a generally rigid, corrosion resistant material. 14. The seal assembly of claim 13, wherein the generally rigid, corrosion resistant material comprises a fluoropolymer. 15. The seal assembly of claim 11, further comprising a first interior rib (2340) extending from an interior surface of the hub portion (2308) and a second interior rib (2344) extending from the interior surface of the hub portion (2308) opposite the first interior rib (2340). 16.
