Abstract: Systems and methods include providing a seal for a valve assembly. The seal includes a metallic annular body having a main body portion, a first sealing leg extending from the main body portion and that provides an axial seal with a component in the valve assembly, and a second sealing leg extending from the main body portion that provides a radial seal with another component of the valve assembly. The seal may also include a sealing ring assembly having a sealing ring support and a sealing ring that forms a radial seal in conjunction with the sealing bumps of the second sealing leg.

Abstract: Systems and methods are disclosed that include providing a valve suitable for maintaining a seal and preventing fluid flow through the valve at cryogenic temperatures. The valve includes a valve body having a longitudinal axis along a flow path through the valve, a ball selectively rotatable within the valve body to selectively allow fluid flow through the valve, a seat insert cavity formed within the valve body, and a seat insert assembly at least partially disposed within the seat insert cavity. The seat insert assembly includes a seat insert comprising at least one sealing lip and a support ring engaged with the at least one sealing lip and configured to bias the at least one sealing lip against a portion of the seat insert cavity to prevent leakage through a second leakage path when the ball valve is selectively rotated to prevent fluid flow through the valve.
