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 formed within the valve body and comprising a cavity having an angled wall, and a seat insert at least partially disposed within the cavity and having a first sealing surface that forms a first sealing interface with the ball to prevent leakage through a first leakage path and a second sealing surface that forms a second sealing interface with the angled wall to prevent leakage through a second leakage path when the ball valve is selectively rotated to prevent fluid flow through the valve.
