323-70240000 - Miller Smith 320 Series High Purity Stainless Steel Regulator CGA 580

Precision Control for High Purity Applications

The Miller Smith 323-70-24-00-00 is a premium high-purity, two-stage regulator from the renowned 320 Silverline Series. Engineered specifically for analytical and process applications where gas purity and corrosion resistance are paramount, this regulator features a body and wetted parts machined from 316 stainless steel bar stock. The use of 316 stainless steel, combined with PCTFE seats, ensures compatibility with a wide range of corrosive and non-corrosive gases, although this specific unit is configured with a CGA 580 connection typically used for inert gases like Nitrogen, Argon, and Helium in high-purity environments.

The regulator's two-stage design is critical for applications requiring stable delivery pressure. Unlike single-stage regulators, which may show a rise in delivery pressure as the supply cylinder empties, the 323-70-24-00-00 maintains a constant output, eliminating the need for frequent manual adjustments. This stability is achieved through a convoluted stainless steel diaphragm that offers exceptional sensitivity and precise control. The metal-to-metal diaphragm seal further enhances the unit's integrity, providing a leak-tight seal that prevents atmospheric contamination of the gas stream—a crucial feature for chromatography and other sensitive analytical techniques.

Safety and versatility are built into the design. The bonnet includes a captured vent port (1/16" FNPT), allowing users to pipe vented gases away to a safe location, which is essential when handling hazardous or toxic media. Additionally, the regulator is designed to withstand internal vacuums, making it suitable for rigorous purging operations during cylinder change-outs. With a maximum inlet pressure of 3500 PSI and a delivery capacity of up to 250 PSI, this Miller Smith regulator represents the gold standard in specialty gas control.
