1. A valve comprising:
a valve body comprising a cavity, an interior bore with a central longitudinal axis, and a radially projecting shoulder;
a flow barrier disposed within said cavity and operable to move between an open position in which the interior bore of the valve body is unobstructed and a closed position in which the flow barrier obstructs the interior bore;
a removable bore-end connection connected to the valve body;
a seat comprising a first axial surface adjacent to said interior bore, a first radial surface adjacent to said flow barrier and a second radial surface, the second radial surface being larger than the first radial surface, said seat disposed between the flow barrier and the removable bore-end connection, such that it does not contact the radially projecting shoulder of the valve body.
