Abstract:
A valve for controlling flow in a subterranean well can include a working fluid and a closure member which rotates in response to phase change in the working fluid. A well system can include a valve which controls flow between a wellbore and a tubular string, with the valve including a working fluid and a closure member which rotates in response to phase change in the working fluid. Rotation of the closure member can displace a seat relative to a plug of a check valve.
