Airgas Model C645D350 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 needle valve model has the valve built into the regulator body reducing the gas path

Optional 15 Ra electropolished with faceseal

Designed for a wide range of pressure settings

low maintenance design features a PCTFE seat for wide media compatibility

These 316 stainless steel single-stage high-purity regulators are recommended for non-corrosive analytical

These regulators are recommended for non-corrosive analytical and process applications

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

ultra-low delivery pressure gases

where precise pressure control and low flow rates are required
