Airgas Model C444G660 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

designed to regulate outlet flow

mildly corrosive and process applications where precise flow control is not critical

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

and the threaded-seat design allows for internal vacuum purging

Scaffolding

A diaphragm packless outlet valve with a 1/4" compression tube fitting is provided for flow control and to maintain system purity

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

high-purity regulators are recommended for non-corrosive analytical and process applications where precise flow control is not critical

Convoluted Hastelloy C-22 diaphragms provide excellent regulating characteristics and allow for internal vacuum purging

An automatic reseating relief valve protects regulatorcomponents from over pressurization while the encapsulatedfilter assembly protect the valve seats and extend operatingservice life

lightweight design is extremely convenient
