Abstract
A method of quantifying stem nut thread wear in a valve having a valve stem that is positioned with a stem nut. A tool is mounted to, and rotates with, the stem nut, while simultaneously measuring stem displacement. The method of orienting the stem nut threads where one 360° rotation will capture all of the thread backlash in addition to any stem displacement. The measured stem displacement, including stem nut thread backlash, can then be used, with certain stem geometry parameters, to calculate stem nut thread wear percent and quantify remaining stem nut thread material.
