Steps for developing a fugitive emission packing for valves by

James 8uggs, RM Engineered Products Inc. (Member of FSA and Materials Standards Society} Over the past 15 years, the elindnation of traditional seal/ng materials and clean air legislation have created the need for a fugitive emissions packing for valves. Th/s article describes var/ous criteria that affect sealing performance as it relates to service conditions, the quality of the valve stem packing, and documentation by testing. Test results m presented on torque retention, sealability versus applied torque, effects of live loading, effects of stem finish on sealshility, end the effects of travel speed on sealabflity. These are some of the test factors required for developing fugitive emission packing.
