Abstract:
Movable valve apparatus having conditioned lubricating surfaces are described. An example valve includes a valve packing having a graphite packing ring disposed within a bonnet of the fluid valve and a stem or shaft has a conditioned surface to hold a lubricating material. The conditioned surface of the stem or shaft is disposed within the bonnet and moves the lubricating material relative to and in contact with the graphite packing ring during operation of the fluid valve.
