623-00090000 - Miller Smith 620 Series Silverline High Purity 2-Stage Regulator CGA 580

Precision Control for High Purity Applications

The Miller Smith 623-00-09-00-00 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 gases where maintaining gas stream purity and precise pressure control is paramount. The unit features a robust nickel-plated brass bar stock body, which not only provides a clean, professional aesthetic but also offers significant resistance to diffusion and environmental corrosion.

At the heart of this regulator is a unique stainless steel diaphragm. Unlike elastomeric diaphragms that can outgas or degrade over time, the stainless steel construction ensures maximum accuracy and maintains the integrity of high-purity gases. The metal-to-metal seal between the body and the diaphragm further eliminates potential leak paths, making it a reliable choice for sensitive analytical or process applications. A filtered seat adds another layer of protection, trapping particulates that could otherwise damage the seating surface or contaminate downstream equipment.

Functionally, the two-stage design is critical for applications requiring stable delivery pressure. As the cylinder pressure drops, single-stage regulators typically experience a rise in outlet pressure. This Silverline regulator compensates for inlet pressure fluctuations, delivering a constant outlet pressure of up to 250 PSI regardless of the tank level. It is equipped with a CGA 580 connection, making it suitable for inert gases such as Nitrogen, Argon, and Helium. Safety features include a capturable vent in the bonnet (1/16" FNPT), allowing for the safe piping away of gases in the unlikely event of a diaphragm failure.
