622-01030000 - Miller Smith Silverline 620 Series High Purity Two-Stage Regulator CGA 326

High Purity Precision for Specialty Gases

The Miller Smith 622-01-03-00-00 Silverline High Purity Brass Two Stage Regulator is an exemplary piece of engineering designed for the rigorous demands of specialty gas delivery. Part of the renowned 620 Silverline Series, this regulator is specifically engineered for non-corrosive gases, such as Nitrous Oxide, requiring the utmost precision in pressure control and stream purity. The core of its performance lies in its two-stage design, which provides a constant outlet pressure of 0-100 PSIG regardless of fluctuations in the inlet pressure from the cylinder. This feature is critical in laboratory and analytical environments where pressure stability directly correlates to process accuracy.

Construction quality is paramount in the Silverline series. The body is machined from brass bar stock and finished with nickel plating, offering a robust exterior that resists environmental corrosion while maintaining a professional aesthetic. Internally, the regulator features a unique stainless steel diaphragm. Unlike elastomeric diaphragms that can outgas or degrade, the stainless steel construction ensures zero contamination of the gas stream. This is further reinforced by a metal-to-metal seal between the body and the diaphragm, eliminating the need for gaskets that could introduce impurities. A filtered seat adds a final layer of protection, trapping particulates before they can affect the regulator's performance or downstream equipment.

Safety and versatility are also key components of the 622-01-03-00-00. The bonnet includes a capturable vent (1/16" FNPT), allowing for the safe piping of vented gases away from the work area—a crucial feature when handling potentially hazardous or asphyxiating gases in confined spaces. The unit comes equipped with 2-1/2" single scale gauges that are easy to read, ensuring operators can monitor system status at a glance. With a maximum inlet pressure rating of 3500 PSIG and a CGA 326 connection, this regulator is ready for high-pressure cylinders and demanding duty cycles.
