Airgas Model C445A510 Stainless Steel High Purity Two Stage Pressure Regulator With 1/4" FNPT Connection And Threadless SeatThis series of 316 stainless steel two stage high purity regulators is designed for non corrosive analytical, mildly corrossive and process applications requiring precise, stable delivery pressure control. The two stage design yields a delivery pressure change of less than 0. 01 100 psi inlet change. Convoluted Hastelloy C 22 diaphragms provide excellent regulating characteristics and allow for internal vacuum purging. The metal to metal diaphragm

isobutylene

The check valve cylinder connection prevents air and contaminants from entering the gas stream during cylinder changeout

These regulators also have a proprietary Supelcoat™ coating that prevent interaction of corrosive and volatile compounds in high purity gas mixtures used in EPA analysis

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

24" x 8" Bottom Panel

They are especially useful in semiconductor manufacturing applications

DOT FMVSS125

where precise pressure control and low flow rates are required

toxic and reactive gases

Use the Model 216 when constant delivery pressure is desired
