323-70230000 - Miller Smith 320 Series High Purity SS Regulator, CGA 350, 250 PSI

High Purity Gas Control

The Miller Smith 323-70-23-00-00 is a premium High Purity Two-Stage Regulator engineered for the precise management of specialty gases. Part of the distinguished 320 Silverline Series, this regulator is constructed from 316 stainless steel bar stock, ensuring exceptional resistance to corrosion and maintaining gas stream purity. It is specifically designed for applications involving both corrosive and non-corrosive gases where stable delivery pressure is critical, regardless of fluctuations in cylinder pressure.

At the core of this regulator is a convoluted stainless steel diaphragm featuring a metal-to-metal seal. This design maximizes leak integrity, a vital requirement for handling hazardous or high-purity media. The unit is equipped with a filtered seat to prevent particulate contamination, extending the service life of the component. With a delivery range of 0-250 PSI and a CGA 350 inlet, it is tailored for specific gas services requiring high-pressure stability.

Safety and Reliability

Safety is paramount in the design of the 320 Series. The bonnet features a captured vent port (1/16" FNPT), allowing for the safe piping and venting of hazardous gases in the unlikely event of a diaphragm failure. This feature is essential for laboratory and industrial environments where gas leaks cannot be tolerated. Additionally, the regulator is designed to withstand internal vacuums, making it suitable for purging operations essential in high-purity setups.

The two-stage mechanism ensures that the outlet pressure remains constant even as the inlet pressure drops during cylinder depletion. This eliminates the need for frequent manual adjustments and ensures consistent process parameters. Large 2-1/2 inch single-scale gauges provide clear readability, allowing operators to monitor tank and delivery pressures with ease.
