Two-stage regulator for Inert Gas. Inlet Connection: CGA-580 - Outlet Connection: 9/16”-18 RH

Please note that Delivery Pressure Gauge reads up to 250 PSI. But this regulator delivery pressure range is 0-150 PSI. Delivery gauges are always over-scaled for better precision at higher pressure settings.Two-stage regulators are designed to lower the high pressure in two stages. Exceptionally well suited for high-pressure cylinder applications with long gas delivery times. Requires less readjustment and give a more constant delivery pressure despite changes in inlet pressure. This regulators incorporate all components of a single stage regulator and contain an additional stage to include a second pressure adjusting spring, diaphragm, and valve seat assembly. The first stage is not user adjustable. The pressure adjusting spring is "pre-compressed" at the factory. This allows the first stage to feed pressure to the second (adjustable) stage. The two-step pressure reduction produces a final delivery pressure showing little effect from changes in cylinder pressure.
