Abstract
A valve assembly is provided that includes a flowbody, a valve element movably disposed within the flowbody, and a flat beam spring-energized seal mechanism. The flat beam spring-energized seal mechanism includes a wiper seal carried by one of the flowbody and the valve element and movable between a retracted position and an extended position. The wiper seal includes a wave contour defining at least one seal wave. A flat beam spring is disposed in alignment with the at least one seal wave and configured to move the wiper seal toward the extended position when a force is exerted upon it by the at least one seal wave.
