Low Emissions Valve Packing A.W. Chesterton Company
Block valve fugitive emissions are effectively reduced to below consent degree requirements with this high performance valve stem packing from AW Chesterton. Constructed from an Inconel reinforced graphite, 1622 is a non-hardening, flexible packing that will not shrink or absorb moisture. Provided as a single spool solution, 1622 is easy to install and can be used to standardize your block valve stem packings, thereby reducing inventories and installation errors caused by selecting the wrong packing. 1622 has received the National Pollution Prevention Roundtable’s 2010 Most Valuable Pollution Prevention (MVP2) award for 1622’s emissions reduction capability.
Can be used in a variety of applications to seal light and heavy hydrocarbons, VOC’s, VHAP’s, steam and most non-oxidizing chemicals in Hydrocarbon Processing, Petrochemical and Chemical Industries. In independent API 622 testing, 1622 had an average emissions rate of 12 ppm and a one time maximum of 45 ppm. These extremely low rates were achieved without gland adjustments over 1500 strokes and three temperature cycles.
In independent ChevronTexaco Emissions Test 1622 had an average leakage rate of 14ppmv without gland adjustments. Passed API Fire Test. Warranty of < 100ppm for five years.
