The Miller Smith 323-00-20-00-00 is a premium component within the 320 Silverline Series, engineered specifically for high-purity and corrosive gas applications. Designed with a 316 stainless steel bar stock body, this two-stage regulator provides exceptional resistance to corrosion, making it the ideal choice for managing Carbon Dioxide (CO2) in analytical, laboratory, or harsh industrial environments. The unit features a CGA 320 inlet connection and delivers a stable output pressure range of 0-250 PSI, maintained accurately despite fluctuations in cylinder pressure.
At the core of this regulator's performance is its convoluted stainless steel diaphragm, which utilizes a metal-to-metal seal. This design eliminates the outgassing and permeation issues often associated with elastomeric diaphragms, ensuring the integrity of high-purity gas streams. The regulator is equipped with a 316 stainless steel filtered seat that not only protects the internal mechanism from particulate contamination but also extends the service life of the unit. For safety in hazardous applications, the bonnet includes captured vent ports (1/16" FNPT), allowing potential leaks to be piped away safely.
The two-stage architecture is critical for applications requiring unvarying delivery pressure. As a gas cylinder empties, the inlet pressure drops, which can cause single-stage regulators to increase their output pressure (decaying inlet characteristic). The 320 Series eliminates this variable, providing a flat delivery curve from a full cylinder down to empty. Additionally, the regulator is designed to withstand internal vacuums, facilitating effective purging operations during cylinder changes.
