Aldrich^® corrosive gas regulator with electroless nickel-plated body and cross purge assembly

NB.51

The combination of Monel^® regulator components and proper purging with the cross-purge assembly makes these units virtually impervious to attack from strong acid forming gases that include hydrogen chloride, chlorine, hydrogen fluoride, hydrogen bromide, and silicon tetrafluoride.

Cross-purge assembly eliminates the escape of toxic and flammable gases when changing cylinders and permits purging system with dry, inert gas to prevent corrosion due to gas hydrolysis.

Specifications:

• Single-stage
• Electroless nickel-plated body
• Stainless steel diaphragm
• 316L Stainless steel cross-purge with color-coded ¹/₄ turn valves with ¹/₄ in. NPTM outlets

Request Technical Information Bulletin No. AL-202 for cross-purge techniques.
