    Abstract: A plug valve including a valve body having an inlet port, an outlet port and a central chamber extending between the inlet port and the outlet port. The valve also includes an inlet seal segment within the central chamber and includes a bore extending therethrough and aligned with the inlet port. An outlet seal segment is disposed within the central chamber having a bore extending therethrough and aligned with the outlet port. A plug member is disposed in the central chamber and is moveable between an open position, to facilitate fluid flow through the plug valve, and a closed position, to block fluid flow through the plug valve. First and second side segments are disposed between and interlocked to the inlet and outlet seal segments to encircle the plug member. The side segments are tensioned to preload the seal segments against the plug member to prevent the flow of fluid between the seal segments and the plug member.

    Abstract: A valve assembly adapted for use in oil and gas operations. In one aspect, the valve assembly includes a valve body defining an internal region, an inlet passageway, and an outlet passageway, the inlet and outlet passageways extending into the internal region; a valve seat connected to the valve body and defining a fluid passageway; a clapper extending within the internal region and defining an annular groove; and a seal extending within the annular groove of the clapper and adapted to sealingly engage the valve seat. In an example embodiment, the clapper is actuable between an open configuration, in which fluid flow is permitted through the fluid passageway; and a closed configuration, in which the seal sealingly engages the valve seat to at least partially restrict fluid flow through the fluid passageway.
