323-83230000 - Miller Smith 320 Series High Purity Stainless Steel Regulator CGA 350

Precision Control for High Purity Applications

The Miller Smith 323-83-23-00-00 is a premium component of the 320 Silverline Series, engineered specifically for the rigorous demands of high purity and corrosive gas applications. Designed with a 316 stainless steel bar stock body, this two-stage regulator ensures that gas integrity is maintained from the cylinder to the point of use. 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. This makes it an ideal choice for analytical laboratories, semiconductor manufacturing, and petrochemical processing where contamination cannot be tolerated.

Operational safety and leak integrity are paramount in the design of the 323-83-23-00-00. The regulator utilizes a unique metal-to-metal diaphragm seal, eliminating the need for elastomeric seals that can degrade or outgas over time. This construction provides maximum leak integrity, crucial when handling hazardous or toxic gases. Furthermore, the bonnet is equipped with captured vent ports (1/16 inch FNPT) on both stages. This allows for the safe piping and venting of hazardous gases in the unlikely event of a diaphragm failure, protecting both the operator and the facility environment. The regulator is also robust enough to withstand internal vacuums, making it compatible with standard purging operations required during cylinder changes.

Performance-wise, the two-stage configuration of this Miller Smith regulator offers distinct advantages over single-stage alternatives. It provides a constant delivery pressure of up to 250 PSI regardless of fluctuations in the inlet pressure as the supply cylinder empties. This stability is essential for processes requiring steady flow rates and precise pressure control. The convoluted stainless steel diaphragm further enhances this precision, offering sensitive response to pressure adjustments. Equipped with large, easy-to-read 2-1/2 inch single scale gauges and threaded bonnets for panel mounting, this regulator combines industrial-grade durability with laboratory-grade precision.
