US MB (Single Seal, Balanced Cartridge Design, Metal Bellow Seal)
US MB (Single Seal, Balanced Cartridge Design, Metal Bellow Seal)
Series US MB is an edge welded metal bellows single seal designed for high temperature to moderate pressure applications typically for the petrochemical industry as well as refineries.
This seal has been engineered with a low coefficient of thermal expansion in the shell material and features a uniquely designed bellows profile. These features minimize seal face distortion across the operating temperature range, ensuring reliable performance under demanding conditions.
