220-2009 - Miller Smith Silverline 220 Series High Purity 2-Stage Regulator CGA 580

Reliable High Purity Gas Management

When your work demands absolute precision and cleanliness, the Miller Smith 220-20-09 Silverline Regulator delivers the performance you expect from a top-tier manufacturer. While often used in laboratory settings, this high-purity two-stage regulator is also an excellent asset for specialized welding and industrial applications requiring inert gas regulation with zero fluctuation. Whether you are managing shielding gases for sensitive TIG welding applications or handling calibration gases for safety equipment, the 220-20-09 ensures that your gas delivery remains stable and pure.

The "Two Stage" designation means this regulator works double-time to keep your output pressure rock-steady. In a single-stage regulator, the outlet pressure can creep up as the tank pressure drops—a phenomenon known as the decay effect. The Miller Smith 220-20-09 eliminates this issue by stepping down the pressure twice, guaranteeing that your set delivery pressure of 0-15 PSI remains constant until the tank is practically empty. This feature is invaluable for long-duration tasks where stopping to readjust pressure settings is not an option.

Built to last, this regulator features a fully plated exterior that resists corrosion and keeps the unit looking professional in any shop or lab environment. The internal components are just as impressive, featuring a stainless steel diaphragm that offers superior sensitivity and longevity compared to elastomeric alternatives. It connects via a standard CGA 580 fitting, making it compatible with common inert gas cylinders like Argon, Nitrogen, and Helium. The inclusion of a filtered seat prevents debris from compromising the seal, and the automatic reseating safety relief valve provides peace of mind by protecting against pressure spikes. For professionals who refuse to compromise on quality, the Miller Smith Silverline series is the standard for high-purity regulation.
