623-01090000 - Miller Smith 620 Series Silverline High Purity 2-Stage Regulator, CGA 580, 0-250 PSI

Precision Control for High Purity Applications

The Miller Smith 623-01-09-00-00 Silverline High Purity Brass Two Stage Regulator is engineered to meet the rigorous demands of analytical laboratories and specialty gas applications. Part of the renowned 620 Silverline Series, this regulator is designed specifically for non-corrosive gases where maintaining gas purity and precise pressure control is paramount. The unit features a CGA 580 inlet connection, making it compatible with inert gases such as Argon, Nitrogen, and Helium, and offers a delivery pressure range of 0-250 PSI.

Advanced Two-Stage Design

Unlike single-stage regulators that experience a drop in outlet pressure as the supply cylinder empties, this two-stage regulator provides a constant delivery pressure throughout the life of the cylinder. This feature is critical for sensitive applications like gas chromatography and process control, where pressure fluctuations can compromise results. The first stage reduces the high inlet pressure (up to 3500 PSI) to an intermediate level, while the second stage provides the fine control needed for the final delivery pressure.

Superior Materials and Construction

To ensure the highest level of gas stream purity, the regulator utilizes a stainless steel diaphragm. This choice of material, combined with a metal-to-metal body-to-diaphragm seal, eliminates the potential for outgassing and contamination often associated with elastomeric seals. The body is machined from brass bar stock and nickel-plated to resist corrosion and wear. Furthermore, the seat is protected by a 316 stainless steel filter, preventing particulate matter from damaging the seating surface or entering the downstream process. Safety is also addressed with capturable 1/16" FNPT vent ports in the bonnet, allowing for the safe piping of vented gases if necessary.
