Abstract
A fluid regulating device includes a regulator valve having an inlet, an outlet, and a valve port disposed between the inlet and the outlet. An actuator is coupled to the regulator valve and includes a valve disc that displaces along a longitudinal axis to open and close the fluid regulating device. The valve disc includes a sealing surface disposed adjacent to an outer radial end of the valve disc, and the sealing surface is adapted to sealingly engage the valve port in the closed position. The valve disc also includes an intermediate surface disposed inward of the sealing surface, and a groove is formed in the intermediate surface. The groove extends along a groove axis extending along the intermediate surface normal to the longitudinal axis, and the groove axis is at least partially curved when viewed along the longitudinal axis.
