Abstract
A pressure-induced shut-off valve for a liquid delivery system with a back pressure regulator having a positive shut-off capability is provided. The pressure-induced shut-off valve may incorporate an integrated purge valve or an integrated cross flow nebulizer/vaporizer. The pressure-induced shut-off valve functions as a variable flow restrictor which automatically adjusts itself to provide a constant back pressure in the liquid line.
