Chesterton

Block valve fugitive emissions are effectively reduced to below consent decree 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 and Chemical Processing Magazine's 2011 Vaaler Award for 1622’s emissions reduction capability.
