A valve comprising: a valve body having an inlet, an outlet, and a valve interior in fluid communication with the inlet and outlet; a bonnet removably secured to a top portion of the valve body; a cammed ball element pivotably mounted in the valve interior, an exterior surface of the ball element defining a portion of a sphere, wherein all points on the exterior surface of the ball element are not equidistant from a natural pivot point of the ball element; a seal ring disposed within the valve interior and biased toward the ball element, wherein the seal ring is adapted to sealingly engage the ball element; an anchor ring disposed within the valve interior and secured to the valve body; a seal carrier disposed in the valve interior between the seal ring and the valve body, the seal carrier being removably secured to the anchor ring by a plurality of bolts that are disposed within the valve interior and adapted to be inserted and removed from within the valve interior, wherein a primary leak path exists between the seal ring and the seal carrier and a secondary leak path exists between the seal carrier and the valve body, the primary leak path and the secondary leak path being exposed to fluid pressure within the valve; a bellows seal disposed between the seal ring and the seal carrier, the bellows seal preventing fluid flow through the primary leak path; and an auxiliary seal disposed between the seal carrier and the valve body, the auxiliary seal preventing fluid flow through the secondary leak path; characterized in that the axial displacement of the seal ring away from the seal carrier is limited by a seal retainer that is coupled to the seal carrier. a valve body having an inlet, an outlet, and a valve interior in fluid communication with the inlet and outlet; a bonnet removably secured to a top portion of the valve body; a cammed ball element pivotably mounted in the valve interior, an exterior surface of the ball element defining a portion of a sphere, wherein all points on the exterior surface of the ball element are not equidistant from a natural pivot point of the ball element; a seal ring disposed within the valve interior and biased toward the ball element, wherein the seal ring is adapted to sealingly engage the ball element; an anchor ring disposed within the valve interior and secured to the valve body; a seal carrier disposed in the valve interior between the seal ring and the valve body, the seal carrier being removably secured to the anchor ring by a plurality of bolts that are disposed within the valve interior and adapted to be inserted and removed from within the valve interior, wherein a primary leak path exists between the seal ring and the seal carrier and a secondary leak path exists between the seal carrier and the valve body, the primary leak path and the secondary leak path being exposed to fluid pressure within the valve; a bellows seal disposed between the seal ring and the seal carrier, the bellows seal preventing fluid flow through the primary leak path; and an auxiliary seal disposed between the seal carrier and the valve body, the auxiliary seal preventing fluid flow through the secondary leak path; characterized in that the axial displacement of the seal ring away from the seal carrier is limited by a seal retainer that is coupled to the seal carrier.
