摘要： Methods and apparatus to load a valve packing are described. An example method disclosed herein includes adjusting a packing flange nut to a position corresponding at least approximately to a free condition of a biasing assembly, coupling a first gauge member to a first flange, adjusting a first gap between a first surface of the first gauge member and a reference surface opposite the first flange to a first predetermined distance, and tightening the packing flange nut so that the first surface of the first gauge member substantially aligns with or engages the reference surface and causes a load assembly to provide a first predetermined packing stress to the valve packing when the first gauge member substantially aligns with or engages the reference surface.
