323-70220000 - Miller Smith 320 Silverline Series High Purity Stainless Steel Two-Stage Regulator CGA 330

High Purity Precision for Corrosive Environments

The Miller Smith 323-70-22-00-00 is a premium component of the 320 Silverline Series, engineered specifically for the rigorous demands of high purity and specialty gas regulation. This two-stage regulator is constructed from 316 stainless steel bar stock, ensuring maximum resistance to corrosion and maintaining the integrity of the gas stream. It is designed to handle both corrosive and non-corrosive gases, making it a versatile tool for laboratory, petrochemical, and advanced industrial applications where gas purity cannot be compromised.

At the core of this regulator's performance is its convoluted stainless steel diaphragm, which provides precise pressure control and sensitivity. The metal-to-metal diaphragm seal eliminates the need for elastomeric seals in the gas stream, thereby maximizing leak integrity and reducing the risk of contamination. The unit features a 316 stainless steel filtered seat that further protects the gas stream purity and extends the service life of the regulator by preventing particulate damage. With a delivery range of 0-250 PSI and a maximum inlet pressure of 3500 PSI, it is robust enough for high-pressure cylinders while delivering fine control.

Safety is paramount in the design of the 323-70-22-00-00. It includes captured vent ports in the bonnet (1/16 inch FNPT), allowing for the safe piping and venting of hazardous gases in the unlikely event of a diaphragm failure. This feature is essential when working with toxic or flammable gases. The regulator is also designed to withstand internal vacuums during purging operations, a critical capability for maintaining system purity during cylinder changes. Note that a Cross Purge Assembly is recommended for use with this series to ensure effective purging of hazardous gas traces.

The regulator is equipped with large, 2-1/2 inch single scale gauges that are easy to read, ensuring operators can monitor cylinder and delivery pressure at a glance. The front and rear bonnets are threaded, facilitating front panel mounting for integrated system setups. This unit comes with a CGA 330 connection, typically used for specific corrosive gases, ensuring compatibility with standard industrial cylinders.
