Abstract:
1. A fluid regulator comprising: means for regulating a fluid pressure at an inlet of the fluid regulator relative to a pressure set-point provided by means for loading the fluid regulator; means for actuating the means for regulating, the means for actuating having means for sensing that defines a loading chamber and a sensing chamber, the loading chamber to receive the means for loading and the sensing chamber to sense the fluid pressure at an inlet of the fluid regulator; means for operatively decoupling a force imparted to the means for regulating by the means for loading when the fluid pressure at the inlet is less than the pressure set-point provided by the means for loading and the means for regulating is in a closed position to prevent or restrict fluid flow through the fluid regulator; and means for providing a seat load to the means for regulating when the means for regulating is in the closed position.
