Airgas Model C444F346 Stainless Steel High Purity Single Stage Pressure Regulator With 1/4" FNPT Connection And Threadless SeatThese 316 stainless steel single stage high purity regulators are recommended for non corrosive analytical, mildly corrosive and process applications where precise flow control is not critical. A specially designed, convoluted Hastelloy C 22 diaphragm provides good regulating performance and maximum purity integrity without the need for a soft seal, which often can be a source of contamination. Each regulator is capable of withstanding an internal

and semiconductor processing

Composite bonnets - reduce weight and extend finish in outdoor environments

convoluted Hastelloy® C-22 diaphragm provides good regulating performance and maximum purity integrity without the need for a soft seal

Scaffolding

Captured bonnet ports with optional vent adapters are standard on both stages and allow the venting of hazardous gases in the event of diaphragm failure

single-stage regulators is designed for liquid cylinders

An automatic reseating relief valve protects regulator components from over pressurization

A preset safety relief valvemakes these regulators suitable for use only with non-corrosive gases

andnon-corrosive gas mixtures for analytical instrumentation

This series is ideally suited for high-pressure testing

These regulators can handle flows up to 250 liters per minute of nitrogen with only a 5 psig pressure drop
