Airgas Model C444D590 Supelcoat™ Coated Stainless Steel High Purity Single Stage Pressure Regulator With 1/4" FNPT Connection And Threadless Seat Two Stage single-stage line regulators is recommended

single-stage line regulators is recommended for applications where diffusion resistance is required

Since this regulator is dome loaded by a remote sensing pilot regulator

two-stage regulators is recommended for non-corrosive analyticaland process applications where precise pressure control isrequired

Convoluted 316 stainless steel diaphragms provide excellent regulating characteristics and corrosion resistance

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

Airgas Model C444D590 Supelcoat™ Coated Stainless Steel High Purity Single Stage Pressure Regulator With 1/4" FNPT Connection And Threadless Seat Two Stage single-stage line regulators is recommendedThese 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
