AIRGAS Y11244B320-AG SINGLE STAGE BRASS 0-50 PSI ANALYTICAL REGULATOR CGA-320

This analytical series of high-purity brass single-stage regulators is recommended for non-corrosive analytical and process applications where precise pressure control is not required. The check valve cylinder connection prevents air and contaminants from entering the gas stream during cylinder change out. This creates consistencies in processes and extends column life in GC applications. Machined from brass bar stock, this regulator body has minimal internal volume - there are no large cavities and pockets associated with forged-body regulators. An automatic reseating relief valve protects regulator components from over pressurization. Nickel-plating makes sure it looks good through many years of service. The valve is built into the regulator body reducing the gas path. These models feature encapsulated filter assemblies to protect the valve seat from contamination, extending regulator service life while also reducing velocity of gas when opening high-pressure cylinder valves.
