摘要： A pressure control assembly is provided that is coupled to a fluid regulator having a regulator body, an actuator, and an exhaust vent. The actuator includes an actuator housing, a diaphragm disposed within the actuator housing, a first chamber defined adjacent a first side of the diaphragm, and second chamber defined adjacent a second side of the diaphragm. The exhaust vent is formed in the actuator housing to fluidly couple the first chamber to the atmosphere. The pressure control assembly includes a flexible element positioned within an orifice of the exhaust vent. The flexible element is movable within the orifice in response to changes in the pressure in the second chamber.
