Airgas Model N245B580 Brass High Purity Two Stage Pressure Regulator With 1/4" FNPT Connection And Non-Lubricated Check ValveThis series of two stage, high purity regulators is designed for non corrosive analytical and process applications requiring precise, stable, delivery pressure control. The two stage design yields a delivery pressure of less than 0. 02 100 psi inlet change. These regulators come with a CGA nipple that has a special high purity, non lubricated check valve incorporated into nose and prevents air and contaminants from entering the gas stream during

The optional bonnet vent adapter allows venting of hazardous gases in the event of diaphragm failure

These regulators also have a check valve cylinder connection that prevents contaminates from entering during cylinder changeover

Also for chromatography processes where the gas cannot be compromised by any interaction

They are available with a CGA-cylinder valve connection for use on large cylinders

single-stage regulators is recommended for non-corrosive analytical and process applications
