322-70320000 - Miller Smith 320 Series High Purity SS Two-Stage Regulator CGA 590

High Purity Precision for Specialty Gases

The Miller Smith 322-70-32-00-00 is a premium high-purity, two-stage regulator from the renowned 320 Silverline Series, specifically engineered for the precise control of both corrosive and non-corrosive gases. Constructed with a robust 316 stainless steel bar stock body and a 316 stainless steel filtered seat, this regulator ensures maximum gas stream purity and extended service life, even in the most demanding industrial and laboratory environments. The unit features a convoluted stainless steel diaphragm that provides exceptional sensitivity and pressure control, utilizing a metal-to-metal diaphragm seal to ensure high leak integrity.

Designed for operational stability, the two-stage mechanism maintains a constant delivery pressure of 0-100 PSIG regardless of fluctuations in the inlet pressure, making it ideal for applications requiring unwavering accuracy. The regulator is equipped with PCTFE wetted parts for enhanced corrosion resistance. Safety is paramount in the design, featuring captured vent ports (1/16" FNPT) in the bonnet to allow 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 during purging operations, ensuring safety during cylinder changes.

Technical Excellence

This regulator is designed to handle a maximum inlet pressure of 3500 PSIG and connects via a CGA 590 fitting. The inclusion of large, 2-1/2 inch single scale gauges allows for easy monitoring of system status. The front and rear bonnets are threaded, facilitating front panel mounting for integrated system setups. Note that a Cross Purge Assembly is recommended with this series to ensure effective purging of hazardous gas traces.
