ABSTRACT:
A process for manufacturing an air flow throttle valve assembly in which the valve disc or blade is precisely sized and centered after assembly to the shaft and throttle body by heating and squeezing of the disc, preferably while the shaft is held at a shallow angle to extrude the perimeter slightly out to the bore wall. After cooling, the shaft angle is reset to a slightly greater angle.
