Abstract: An energizing element including: an energizing element body oriented about a central axis, the energizing element body defining an inner radius, IR, and an outer radius, OR, where the difference between the outer radius and the inner radius defines an adjusted width, W, of the energizing element body, where the inner radius and the outer radius determine an average radius, R, of the energizing element body about the central axis, where the energizing element body defines an aspect ratio, W/R, where W/R>0.1, where the energizing element body has a maximum linear contact length on the inner radius, LIR, where the energizing element body has a perimeter on the inner radius, PIR, and LIR/PIR>0.80, where the energizing element body has a maximum linear contact length on the outer radius, LOR, where the energizing element body has a perimeter on the outer radius, POR, and LOR/POR>0.55, and where the adjusted width is less than 5 mm.

Abstract: Systems and methods include providing a seal for an assembly. The seal includes a jacket having a base, an inner sealing leg, and an outer sealing leg, and further includes a spring disposed within the jacket between and in contact with the inner sealing leg and the outer sealing leg. The spring includes an annular support ring disposed within the spring. The support ring biases an outer diameter (OD) of the spring towards the outer sealing leg of the jacket to maintain contact pressure between the inner sealing leg of the jacket and the shaft of the assembly. The support ring controls thermal shrinkage of the spring and the outer sealing leg to maintain a seal between a housing and a shaft of the assembly when the assembly is operated at cryogenic temperatures.

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, a ball selectively rotatable within the valve body, a seat having a seat insert at disposed within the valve body and configured to form a seal with the ball, and a seal disposed within a cavity formed between the valve body and the seat. The seal includes a seal body having a heel, an upper leg and a lower leg extending from the heel, and a cavity comprising a first cavity portion and a second cavity portion disposed between the upper leg and the lower leg. The first cavity portion includes at least one energizing element, and the second cavity portion may be free of an energizing element or include an energizing element.

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.

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.
