Abstract
Seal assemblies for valves may include a movable seat configured to be disposed in a chamber of a valve. In an initial position, the movable seat is configured to contact a proximal portion of a plug head of the valve at an annular location that is spaced from a distal portion of the plug head during a closing stroke of the plug head. A biasing element is configured to bias the movable seat in the initial position and to enable the movable seat to move in a direction of the closing stroke of the plug head against a biasing force of the biasing element.
