Description

Technical Field

[0001] Valves are used to control the flow of fluids in a wide range of applications. A ball valve is typically used in applications where it is necessary to shut off the flow of fluid through the ball valve. The shutoff and establishment of the fluid flow through the ball valve are achieved by the selective actuation of the ball within the ball valve. Generally, a seat insert within the ball valve provides a seal against the ball and a portion of the ball valve body. However, when the ball valve is exposed to extreme environmental conditions such as cryogenic temperatures, the seat insert and / or other parts of the ball valve may shrink, deform, or otherwise change, thereby allowing fluid leakage through the ball valve. Therefore, the industry continues to demand improvements in ball valve technology for such applications.
