Abstract:
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.
