623-20100000 - Miller Smith Silverline 620 Series High Purity 2-Stage Regulator CGA 590

Precision Control for High Purity Applications

The Miller Smith 623-20-10-00-00 Silverline High Purity Brass Two Stage Regulator is engineered for professionals who demand exacting standards in gas delivery. Part of the renowned 620 Silverline Series, this regulator is specifically designed for non-corrosive specialty gases requiring precise and stable delivery pressure control. The unit features a robust nickel-plated brass bar stock body that provides excellent diffusion resistance, ensuring the integrity of the gas stream is maintained from the cylinder to the application point.

At the heart of this regulator is a unique, specially designed stainless steel diaphragm. Unlike elastomeric diaphragms that can outgas or permeate, the stainless steel construction offers a metal-to-metal seal against the body, guaranteeing maximum accuracy and maintaining system purity. This design is critical for analytical applications where even trace contamination can compromise results. The regulator also includes a 316 stainless steel filter at the seat to prevent particulate damage, further extending the service life of the unit.

The two-stage architecture of the 623-20-10-00-00 is a key differentiator. By reducing cylinder pressure in two steps, the regulator provides a constant outlet pressure of 0-250 PSI regardless of fluctuations in inlet pressure. This means as your gas cylinder empties and pressure drops, your delivery pressure remains rock-steady without the need for constant manual adjustment. Safety is also paramount; the bonnet features a capturable vent (1/16" FNPT) on both stages, allowing for the safe piping away of gases in the unlikely event of a diaphragm failure.

Equipped with a CGA 590 inlet connection, this model is tailored for specific industrial gases such as Sulfur Hexafluoride (SF6) and other compatible specialty mixtures. With a maximum inlet pressure rating of 3500 PSI and large, easy-to-read 2-1/2 inch single scale gauges, the Miller Smith 623-20-10-00-00 stands as a premier choice for laboratory, research, and high-precision industrial environments.
