322-66220000 - Miller Smith 320 Series High Purity Stainless Steel Two Stage Regulator, CGA 330, 0-100 PSI

High Purity Precision for Corrosive Environments

The Miller Smith 322-66-22-00-00 is a premier component of the 320 Silverline Series, engineered specifically for the rigorous demands of high purity and corrosive gas applications. This two-stage regulator is meticulously crafted from 316 stainless steel bar stock, ensuring exceptional durability and resistance to chemical attack. The unit features a 316 stainless steel filtered seat which not only enhances the purity of the gas stream but also significantly extends the service life of the regulator by preventing particulate damage. Designed for critical applications in laboratories, petrochemical facilities, and semiconductor manufacturing, this regulator maintains a constant delivery pressure of 0-100 PSI regardless of fluctuations in the inlet pressure, providing the stability required for sensitive instrumentation.

Leak integrity is paramount when handling hazardous or expensive specialty gases. The Miller Smith 320 Series addresses this with a unique metal-to-metal diaphragm seal, eliminating the need for elastomeric seals that can degrade or outgas over time. The convoluted stainless steel diaphragm offers superior sensitivity and precise control over outlet pressure. For enhanced safety, the regulator includes captured vent ports (1/16" FNPT) on both stages. This critical feature allows for the piping of hazardous fumes away from the work area in the unlikely event of a diaphragm failure, ensuring operator safety. Furthermore, the design is robust enough to withstand internal vacuums, making it suitable for purging operations essential in high-purity setups.

Operational clarity is provided by large, 2-1/2 inch single scale gauges that are easy to read at a glance. The front and rear bonnet threads facilitate front panel mounting, offering versatility in system integration. Whether managing corrosive gases or requiring absolute purity for analytical work, the Miller Smith 322-66-22-00-00 delivers the reliability and performance professionals demand. Note that a Cross Purge Assembly is recommended for use with this series to ensure effective purging of hazardous gas traces during cylinder changes.
