Powell Valves, Chesterton Develop Exclusive Partnership

Two longtime industrial suppliers, The Wm. Powell Company and A.W. Chesterton Company, announced an agreement in which Chesterton will become the exclusive supplier of its low-emissions packing technology in Powell Valves.

The agreement allows Powell to produce valves that are compliant with the new API 624 standard for industrial fugitive emissions and to meet the latest EPA regulations. API 624 requires that valves be manufactured to reduce fugitive emissions to 100 ppm or less for five years, which will result in reduced air pollutants.

The EPA estimates that 60% of fugitive emissions at oil refineries and chemical plants are attributed to valves, with flanges, pumps, compressors and other components responsible for the remainder. As part of its stepped-up enforcement of clean-air standards, the EPA has negotiated consent decrees with about 85% of refineries, requiring enhanced leak detection and reduced emissions.

Powell said valves in its existing inventory can be refitted with Chesterton’s 1622 Low-E packing upon request from the customer.
