The Miller Smith 621-01-09-00-00 Silverline High Purity Brass Two Stage Regulator is engineered for applications demanding the utmost precision and gas purity. Part of the renowned 620 Silverline Series, this regulator is specifically designed to handle non-corrosive gases where stable delivery pressure is critical. Unlike single-stage regulators that suffer from delivery pressure decay as the cylinder empties, this two-stage unit maintains a constant outlet pressure throughout the life of the cylinder, ensuring consistent performance for analytical instruments and sensitive processes.
At the heart of this regulator is a unique stainless steel diaphragm. This component is crucial for maintaining high purity standards, as it provides a metal-to-metal seal against the body, eliminating the outgassing and contamination risks associated with elastomeric diaphragms. The body itself is machined from brass bar stock and finished with nickel plating, offering a robust and corrosion-resistant exterior that withstands the rigors of industrial and laboratory environments. A 316 stainless steel filter is integrated into the seat assembly to trap particulates, further protecting the seat and ensuring the purity of the gas stream.
Safety is paramount in high-pressure gas handling. The 620 Series features a capturable vent in the bonnet (1/16" FNPT), allowing users to pipe vented gases away from the work area in the event of a diaphragm failure—a critical feature when working in confined spaces or with specific gas mixtures. The regulator is equipped with a CGA 580 connection, making it compatible with standard inert gas cylinders such as Argon, Nitrogen, and Helium. With a maximum inlet pressure rating of 3500 PSIG and a precise delivery range of 0-60 PSIG, this regulator is the ideal choice for gas chromatography, emission spectroscopy, and other high-purity applications.
