Abstract
Valve bodies having integral boost reducing capability are described herein. An example fluid regulator includes a body having a main passageway defining an orifice to fluidly couple an inlet and an outlet where the main passageway defines an inlet volume boundary between the inlet and the orifice and an outlet volume boundary between the orifice and the outlet. A portion of the outlet volume boundary includes an inner wall adjacent the orifice. A valve plug is disposed within the second portion of the passageway such that the inner wall substantially surrounds an outer surface of the valve plug to substantially restrict fluid flow between the inner wall and the outer surface of the valve plug and toward the throat. The valve body having a secondary fluid passage within the outlet volume boundary to increase fluid flow toward the throat of the valve body when a fluid flows across the orifice.
