A valve assembly includes a valve body defining an internal region, an inlet passageway, and an outlet passageway, wherein the inlet and outlet passageways fluidly communicate with the internal region. A valve seat is positioned within the internal region defining a fluid passageway. A hanger is connected to the valve body. A linkage assembly is pivotally and rotatably to the hanger and a valve member is pivotally connected to the hanger via the linkage assembly, wherein the valve member is movable between an open configuration, in which fluid flow is permitted through the fluid passageway, and a closed configuration, in which the valve member engages the valve seat to at least partially restrict fluid flow through the fluid passageway.
