Airgas Model C645F350 Stainless Steel High Purity Two Stage Pressure Regulator With 1/4" FNPT Connection And Threaded SeatThis series of two stage, high purity 316 stainless steel regulators is designed for non corrosive analytical and process applications requiring precise, stable delivery pressure control. The two stage design yields a delivery pressure change of less than 0. 04 100 psi inlet change. Convoluted 316 stainless steel diaphragms provide excellent regulating characteristics and corrosion resistance, and the threaded seat design allows for internal vacuum

The two-stage design yields a delivery pressure of less than 0

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

two-stage regulators is recommended for non-corrosive analytical and process applications where precise pressure control required
