Gases & Equipment

For mildly-corrosive and high-purity gas applications

Z562610-1EA

Purge valve sits between the lecture-bottle and regulator to purge system with inert gas to remove air, moisture, and process gas to maintain high-purity conditions and to minimize gas hydrolysis and corrosion damage to equipment.  Purge system with dry, inert gas before introducing mildly corrosive gases and again immediately after use.

For strong, acid-forming gas applications

Z562629-1EA

For use with hydrogen chloride, hydrogen, bromide, hydrogen fluoride, and silicon tetrafluoride.  Cross-purge valve sits between the lecture-bottle and regulator to prevent escape of toxic and flammable gases when changing cylinders and permits purging system with inert gas to remove air, moisture, and process gas to minimize gas hydrolysis and corrosion damage to equipment.  Purge system with dry, inert gas before introducing corrosive gases and again immediately after use.
