Airgas Model 820H580 Brass Heavy Duty High Pressure Cylinder Regulator With 1/4" FNPT ConnectionThis series of Airgas heavy duty high pressure cylinder regulators is recommended for use on cylinders or panel mounting with a wide variety of non corrosive inert gases. This series is ideally suited for high pressure testing, purging and charging, calibration kits, manufacturing processes and RandD laboratories. The Airgas heavy duty high pressure cylinder regulators piston sensor design provides structural reliability in high pressure applications.

Stainless Steel Diaphragmseliminates outgassing associated with elastometric diaphragms

these single-stage regulators are recommended for use in petroleum field applications

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

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

allows the exterior surfaces to maintain a good appearance in outdoor environments

Two-stage design

The two-stage design yields a delivery pressure change of less than 0

This creates consistencies in processes and extends column life in GC applications

06 psig for every 100 psig of inlet pressure decay

These regulators are recommended for use on low-pressure pipelines serving gas chromatographs

000 liters per minute without the resonance problems associated with other regulators in this same application

These regulators have a unique design to reduce weight and make the regulator more durable
