221-0109 - Miller Smith Silverline 220 Series High Purity Two-Stage Regulator, CGA 580, 0-50 PSI

Rugged Reliability for Industrial Gas Control

The Miller Smith 221-01-09 Silverline Regulator brings laboratory-grade precision to the industrial workspace. While it is designed for high-purity analytical applications, its robust construction makes it a favorite among maintenance and repair professionals who demand the best in gas regulation equipment. This two-stage regulator is built to perform consistently in demanding environments, offering a stable delivery pressure of 0-50 PSIG without the need for constant readjustment as the supply cylinder drains. This "set and forget" capability allows operators to focus on their tasks rather than monitoring gauge fluctuations.

Constructed from rugged brass bar stock and finished with a durable plating, the 221-01-09 is designed to resist corrosion and withstand the wear and tear of daily use. The CGA 580 inlet connection makes it compatible with standard inert gas cylinders, such as Argon, Helium, and Nitrogen, commonly used in welding and industrial processes. The regulator features a stainless steel diaphragm, which offers superior longevity compared to rubber alternatives, ensuring that the unit maintains its responsiveness and accuracy over years of service. This makes it an excellent investment for facilities looking to minimize equipment replacement costs and downtime.

Safety and ease of use are key features of the Silverline series. The regulator is equipped with large 2-1/2 inch single scale gauges that provide clear, instant visibility of cylinder and delivery pressures. It also includes an automatic reseating safety relief valve to protect the equipment and the operator from pressure spikes. Furthermore, the design allows the regulator to withstand vacuum purging, ensuring that lines can be effectively cleared of contaminants before gas delivery begins. Whether used for specialized welding shielding gas, calibration stations, or general industrial gas control, the Miller Smith 221-01-09 delivers the reliability and performance synonymous with the Miller name.
