Airgas Single Stage Brass 0-250 psi Analytical Cylinder Regulator CGA-590 Switchover non-lubricated check valve incorporated into

non-lubricated check valve incorporated into nose and prevents air and contaminants from entering the gas stream during cylinder change out

Convoluted Hastelloy® C-22 diaphragms provide excellent regulating characteristics and allow for internal vacuum purging

non-corrosive gas applications where precise delivery pressure is critical

Because these regulators are not typically recommended for direct connection to cylinders

Airgas Single Stage Brass 0-250 psi Analytical Cylinder Regulator CGA-590 Switchover non-lubricated check valve incorporated intoThis 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
