A gas regulator comprises an actuator and a valve body, wherein the actua tor includes a valve disc with a cylindrical shroud that extends beyond the valve disc to direct the flow of fluid through the regulator toward the outl et of the valve and away from the actuator. This configuration advantageousl y reduces the amount of pressure drop experienced by the actuator during nor mal operation, thereby minimizing a phenomenon known as "droop." At least in one embodiment, the shroud can be adjustable and/or removable to allow the regulator to be tuned for specific applications.
