Bellow Seal Globe Valves : Stem Sealing, Emission Control and Selection Guide
Learn how bellow seal globe valves use a welded metal bellows assembly to reduce stem leakage and fugitive emissions in high-temperature, hazardous, toxic, steam, thermal oil, and chemical service. The guide explains bellows sealing principles, backup packing, material selection, cycle-life considerations, pressure-temperature requirements, emission-control standards, and key selection factors for critical industrial piping systems.
