Airgas Single Stage Brass 0-100 psi Analytical Cylinder Regulator CGA-590 With Needle Outlet

Check Valve Cylinder Connections Prevents air and contaminants from entering process stream during cylinder change out Stainless Steel Diaphragms eliminates out gassing associated with elastometric diaphragms. Bar Stock Body for low internal volume. Encapsulated Filter Seat Assy for added gas stream purity and extended service life. Nickel-Plated Brass Body provides long-lasting good looks Includes will not tarnish. Mounting front panel mount bonnet and (2) 10-32 taps for rear mounting.

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.
