Achieving Low E Fugitive Emissions Compliance in Chemical Industry Valve Stem Sealing A.W.
Chesterton has done extensive testing and is able to warrant our 1724 Low E Sealing System for Low E technology to 100 ppm for 5 years. Testing for both block and control valves resulted in average leakage rates in the single digit ppms with maximum leakage rates in the low double digits per EPA Method 21, without a retorque.
Chesterton’s 1724 Low E Sealing System has been approved and specified by several major chemical company’s to meet their Low E consent decree requirements for VOC and HAP fugitive emissions.
