Valve stem finish effect on fugitive emissions

How valve stem finish affects fugitive emissions performance in relation to graphite packing and material deposition

How stem finish affects friction and fugitive emissions with graphite-based control valve packing.

A well designed and efficiently performing control valve can have a significant impact on process profitability, via reduced process costs, ecological factors and safety via fugitive emissions. We have previously reported that whist control valves are perhaps only 5% of a refinery valve population; they are statistically twice as likely to be found leaking in an emission survey, as of course they are continually in operation and thus pose a greater problem than block valves.
