322-81240000 - Miller Smith 320 Series High Purity 2-Stage Stainless Steel Regulator CGA 580

Precision Control for High Purity Applications

The Miller Smith 322-81-24-00-00 is a premium component of the 320 Silverline Series, engineered specifically for the rigorous demands of specialty gas delivery. This high-purity, two-stage regulator is constructed from 316 stainless steel bar stock, making it an ideal choice for applications involving corrosive gases or environments where maintaining absolute gas purity is critical. The unit features a CGA 580 inlet connection, typically used for inert gases such as Argon, Helium, and Nitrogen, and provides a precise delivery pressure range of 0-100 PSIG.

Technically, the regulator excels due to its advanced internal architecture. It utilizes a convoluted stainless steel diaphragm that provides exceptional sensitivity and control over outlet pressure. A key engineering feature is the metal-to-metal diaphragm seal, which ensures maximum leak integrity—a vital requirement when handling expensive or sensitive specialty gases. Furthermore, the seat is filtered with 316 stainless steel to prevent particulate contamination, thereby extending the service life of the regulator and ensuring the purity of the downstream gas.

Safety and versatility are also paramount in the design of the 322-81-24-00-00. The bonnet includes captured vent ports (1/16 inch FNPT) on both stages, allowing for the safe piping and venting of hazardous gases in the unlikely event of a diaphragm failure. The regulator is also designed to withstand internal vacuums, making it compatible with purging operations essential for maintaining system purity during cylinder changes. With a maximum inlet pressure rating of 3500 PSIG and large, easy-to-read 2-1/2 inch gauges, this regulator offers a robust solution for analytical laboratories, petrochemical processing, and pharmaceutical manufacturing.
