322-00220000 - Miller Smith 320 Series SS Two-Stage Regulator CGA 330 100 PSI

High Purity Stainless Steel Regulation

The Miller Smith 322-00-22-00-00 is a premium two-stage regulator designed specifically for high-purity and corrosive gas applications. Part of the renowned 320 Silverline Series, this regulator is engineered to provide precise, stable delivery pressure control regardless of fluctuations in the inlet pressure. This capability is critical in laboratory and specialty gas environments where consistency is paramount. The unit features a body and wetted parts constructed from 316 Stainless Steel and PCTFE, offering exceptional resistance to corrosion and ensuring the purity of the gas stream is maintained without contamination from the regulator itself.

Advanced Design Features

At the heart of this regulator is a convoluted stainless steel diaphragm that provides superior sensitivity and control accuracy. Unlike elastomeric diaphragms, the metal-to-metal diaphragm seal ensures maximum leak integrity, a vital feature when handling hazardous or expensive specialty gases. The design includes a 316 stainless steel filtered seat which not only adds to the gas stream purity but also significantly extends the service life of the regulator by preventing particulate damage.

Safety and Versatility

Safety is a core component of the 322-00-22-00-00's design. It comes equipped with captured vent ports (1/16" FNPT) in the bonnet. This allows for the safe piping and venting of hazardous gases in the unlikely event of a diaphragm failure, protecting personnel and the environment. The regulator is rated for a maximum inlet pressure of 3500 PSI and provides a delivery pressure up to 100 PSI. It is equipped with large, easy-to-read 2-1/2 inch single scale gauges, making monitoring simple and accurate. The front and rear bonnet threads also facilitate front panel mounting, adding to its versatility in system integration.

Application Suitability

This regulator is specifically outfitted with a CGA 330 connection, typically used for corrosive gases. It is designed to withstand internal vacuums during purging operations, which is essential for maintaining system purity during cylinder changes. Note that a Cross Purge Assembly is recommended with this series to ensure effective purging of hazardous gas traces. Whether for analytical instrumentation, process control, or semiconductor manufacturing, the Miller Smith 320 Series delivers the reliability and performance required for critical applications.
