321-85250000 - Miller Smith 320 Series High Purity Stainless Steel Regulator, CGA 660, 50 PSI

High Purity Control for Corrosive Environments

The Miller Smith 321-85-25-00-00 is a premium high-purity, two-stage regulator designed specifically for the rigorous demands of handling corrosive and specialty gases. Part of the 320 Silverline Series, this unit is engineered to provide precise, stable delivery pressure regardless of fluctuations in the inlet pressure, making it an essential component for analytical laboratories, research facilities, and industrial applications requiring exacting standards.

Constructed from 316 stainless steel bar stock, the regulator body offers superior resistance to corrosion, ensuring longevity even when used with aggressive media. The wetted parts, including the diaphragm and filtered seat, are also manufactured from 316 stainless steel and PCTFE, maintaining the purity of the gas stream and preventing contamination. A unique metal-to-metal diaphragm seal enhances leak integrity, a critical feature when dealing with hazardous or expensive gases.

Safety and operational efficiency are paramount in the design of the 321-85-25-00-00. It features 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. The regulator is also designed to withstand internal vacuums, facilitating effective purging operations during cylinder changes. Large 2-1/2 inch single scale gauges provide clear, easy-to-read pressure monitoring, ensuring operators can maintain optimal system performance with confidence.
