Abstract: The disclosed embodiments include systems and methods for retaining a seat insert of a ball valve in place within a seat ring of the ball valve. In particular, the seat insert is an annular ring having a tapered section on an outer wall of the annular ring. The tapered section of the seat insert is configured to mate with a shoulder in an outer surface of a profiled groove of the seat ring. The seat insert snaps into the profiled groove with the shoulder, thereby preventing axial movement of the seat insert with respect to the profiled groove of the seat ring. In addition, a locking ring also fits within the profiled groove of the seat ring to prevent axial and radial movement of the seat insert with respect to the profiled groove of the seat ring. More specifically, once the seat insert has been snapped into place within the profiled groove of the seat ring, the locking ring is also inserted into the profiled groove of the seat ring.

Abstract: The disclosed embodiments include systems and methods for energizing a ball valve seat assembly. In particular, the disclosed embodiments are directed toward energizing devices that generate linear or substantially linear energizing forces. In other words, as a seat of the ball valve translates axially with respect to a ball of the ball valve, the resulting energizing force that biases the seat ring back toward the ball is substantially directly proportional to the amount of axial translation. In certain embodiments, the linear energizing device includes an annular cantilevered v-shaped spring having a generally constant cross-sectional profile, including a pair of legs extending from a curved end.
