Flexible seals for process control valves are disclosed. An example disclosed seal includes a seal for use with a butterfly valve. The example seal includes a substantially flexible ring-shaped carrier configured to be moveably fixed within the butterfly valve and to surround a flow control aperture therein. The example seal includes a seal stiffener adjacent the substantially flexible ring-shaped carrier to increase the stiffness of the substantially flexible ring-shaped carrier in a first flow direction. The example seal includes a substantially rigid seal ring to engage an opposing surface.

1. A seal for use with a butterfly valve, the seal comprising: a flexible carrier to surround a flow control aperture;a seal stiffener adjacent the flexible carrier to increase a stiffness of the flexible carrier in a first flow direction; anda seal ring carried by one of the flexible carrier or a flow control member to form a seal with the other of the flexible carrier or the flow control member, the seal ring including a metal layer and a polymer layer. 2. The seal as defined in claim 1, wherein the seal stiffener is disposed between a clamping ring and the flexible carrier. 3. The seal as defined in claim 1, wherein the first flow direction is a reverse flow direction. 4. The seal as defined in claim 1, wherein the seal stiffener is to abut at least a portion of the flexible carrier as the flexible carrier flexes in the first flow direction. 5. The seal as defined in claim 1, wherein the seal stiffener does not interfere with movement of the flexible carrier in a second flow direction. 6. The seal as defined in claim 1, wherein the seal stiffener comprises a plurality of cantilevered members spaced around a circumference of the flexible carrier. 7. The seal as defined in claim 1, wherein the seal stiffener is to protect the flexible carrier from abrasive media. 8. The seal as defined in claim 1, wherein the seal stiffener has an inner diameter substantially equal to an inner diameter of the flexible carrier. 9. The seal as defined in claim 1, wherein the seal stiffener is substantially planar. 10. The seal as defined in claim 1, wherein the seal ring is a laminated structure. 11. The seal as defined in claim 1, wherein the seal ring is coupled to the flexible carrier. 12. The seal as defined in claim 11, wherein the seal ring is coupled to the flexible carrier via a cartridge. 13. The seal as defined in claim 1, wherein the seal stiffener has a contoured profile comprised of two bends. 14. The seal as defined in claim 1, wherein the flexible carrier comprises a curved profile having an inner diameter at a first side and an outer diameter at a second side, the seal stiffener disposed adjacent the first side, and the second side is to seal against the flow control member. 15. The seal as defined in claim 1, wherein the metal layer and the polymer layer are coupled via a layer of graphite. 16. The seal as defined in claim 1, wherein the flexible carrier has a flush side that is substantially parallel to a longitudinal axis of the flow control aperture, and wherein the seal ring is coupled to the flush side of the flexible carrier. 17. The seal as defined in claim 16, wherein the flush side is a radially inner most surface of the flexible carrier. 18. The seal as defined in claim 1, further including a cartridge coupled to the flexible carrier, the seal ring disposed within the cartridge and separate from the flexible carrier. 19. A seal for use with a butterfly valve, the seal comprising: a first flexible carrier to surround a flow control aperture;a seal stiffener adjacent the flexible carrier to increase a stiffness of the flexible carrier in a first flow direction; anda seal ring to form a seal with one or more of the flexible carrier or a flow control member, the seal ring being a layered structure including a first metal layer, a first expanded graphite layer coupled to the first metal layer and a polymer layer coupled to the first expanded graphite layer. 20. The seal as defined in claim 19, wherein the seal ring comprises a second metal layer and a second expanded graphite layer. 21. The seal as defined in claim 20, wherein the polymer layer of the seal ring is disposed between the first and second expanded graphite layers. 22. The seal as defined in claim 20, wherein the first expanded graphite layer is adjacent the first metal layer and the second expanded graphite layer is adjacent the second metal layer. 23. The seal as defined in claim 20, wherein the seal ring comprises at least one additional metal layer between the first and second expanded graphite layers.
