221-2010 - Miller Smith Silverline High Purity Two-Stage Regulator CGA 590

Reliable High Purity Gas Regulation

The Miller Smith 221-20-10 is a premium two-stage regulator from the Silverline series, designed to deliver consistent performance for high-purity gas applications. For welders and industrial technicians working with specialized equipment or laboratory setups, this regulator offers the reliability associated with the Miller brand. The two-stage design is a significant advantage for users who need a steady flow of gas without constant adjustment; it automatically compensates for the drop in cylinder pressure as the tank empties, allowing you to utilize the entire contents of the cylinder without delivery pressure drift.

Built to withstand the rigors of professional use, the regulator features a rugged brass bar stock construction that is plated for superior protection against environmental factors and corrosion. This plating extends to the bonnet and the large, easy-to-read 2-1/2 inch gauges, ensuring the tool remains legible and functional over years of service. The internal components are equally robust, featuring a stainless steel diaphragm that provides precise pressure regulation while preventing gas contamination—a must-have for sensitive analytical work.

Safety is paramount in high-pressure gas handling. The 221-20-10 includes an automatic reseating safety relief valve located on the intermediate stage. This valve protects the regulator's components from over-pressurization and is designed to be capturable, meaning any vented gas can be safely directed away from the work area. The regulator connects via a CGA 590 fitting, rated for inlet pressures up to 3500 PSIG, and delivers a smooth, adjustable output between 0 and 60 PSIG.

Whether you are setting up a gas chromatograph or managing calibration mixtures, the Miller Smith 221-20-10 provides the control you need. Its filtered seat design adds another layer of reliability by preventing debris from damaging the internal seating mechanism. Backed by Miller's reputation for quality, this regulator is an investment in precision and safety for your specialty gas delivery systems.
