320-70320000 - Miller Smith 320 Series High Purity 2-Stage Stainless Steel Regulator CGA 590

High Purity Precision for Specialty Gases

The Miller Smith 320-70-32-00-00 is a premium high-purity, two-stage regulator designed specifically for the rigorous demands of specialty gas delivery. Engineered from high-grade 316 stainless steel bar stock, this regulator is the ideal solution for managing both corrosive and non-corrosive gases where purity and material integrity are paramount. The 320 Silverline series is built to maintain the integrity of your gas stream, featuring a 316 stainless steel filtered seat that prevents contamination and extends the lifespan of the unit.

One of the standout features of this regulator is its two-stage architecture. Unlike single-stage models, this unit provides a constant delivery pressure of 0-25 PSIG regardless of fluctuations in the inlet pressure, ensuring your processes remain stable from the start of the cylinder to the end. The convoluted stainless steel diaphragm offers exceptional sensitivity and precise control, while the metal-to-metal diaphragm seal ensures maximum leak integrity—a critical factor when handling hazardous or expensive gases.

Safety is engineered into every aspect of the design. The regulator includes captured vent ports (1/16" FNPT) in the bonnet, allowing for the safe piping and venting of hazardous gases in the unlikely event of a diaphragm failure. Additionally, the unit is designed to withstand internal vacuums, making it suitable for purging operations essential in high-purity applications. With large, easy-to-read 2-1/2" gauges and a CGA 590 connection, this Miller Smith regulator represents the gold standard for laboratory, analytical, and industrial gas control.
