Valve stem finish and its effect on graphite packing

Research paper looking into the effects of valve stem surface finish and the fugitive emissions performance of graphite compression (braided) packing materials.

Analysis of surface roughness and profile parameters of graphite packing deposition on valve stems and how this influences frictional performance.

A well designed and efficiently performing valve can have a significant impact on process profitability, via reduced process costs, ecological factors and safety via fugitive emissions.
