Abstract
A fluid regulating device includes a regulator valve having a valve body defining an inlet and an outlet and a valve port disposed between the inlet and the outlet. A housing assembly is disposed adjacent the valve port, and the housing assembly includes a first aperture adapted to receive a valve disc. A balancing diaphragm is secured to a portion of the valve disc and a portion of the housing assembly, and a portion of a balancing cavity is defined by a top surface of the balancing diaphragm and an interior surface of the housing assembly. A sensing passage extends from the inlet of the regulator valve to the balancing cavity such that the inlet of the regulator valve is in fluid communication with the balancing cavity.
