Ss316 Bellow Seal Globe Valve

SS316 Bellows Seal Globe Valve – Superior Corrosion Resistance with Zero Emissions

SS316 bellows seal globe valves utilize Type 316/316L austenitic stainless steel (CF8M/CF3M cast grades) throughout wetted components plus 316 stainless bellows, providing enhanced corrosion resistance for chloride-containing environments, marine applications, and aggressive chemicals where Type 304 stainless suffers pitting corrosion. The molybdenum addition (2-3%) in 316 stainless dramatically improves resistance to seawater, brines, and chlorinated process streams common across African coastal facilities, desalination plants, and offshore platforms.

This material-sealing combination addresses simultaneous requirements for zero fugitive emissions (ISO 15848-1 compliance) and corrosion performance in harsh environments including African offshore oil & gas platforms, coastal chemical plants, and seawater-cooled facilities where both environmental regulations and material longevity demand superior metallurgy. The 316L low-carbon variant prevents carbide precipitation during welding, eliminating intergranular corrosion in heat-affected zones critical for welded applications.
