322-69230000 - Miller Smith 320 Series High Purity Stainless Steel Two-Stage Regulator, CGA 350, 100 PSI

Precision Control for High Purity Applications

The Miller Smith 322-69-23-00-00 is a premium offering from the 320 Silverline Series, engineered specifically for the rigorous demands of high purity and specialty gas regulation. This two-stage regulator is constructed from high-grade 316 stainless steel bar stock, making it an ideal choice for environments where corrosion resistance and gas stream purity are non-negotiable. Whether handling corrosive or non-corrosive gases, this unit ensures that the integrity of your process is maintained through superior materials and design.

Advanced Material Construction

At the core of this regulator's performance is its 316 stainless steel filtered seat and convoluted stainless steel diaphragm. The use of 316 SS throughout the wetted parts, combined with PCTFE seating material, provides exceptional resistance to corrosive elements while preventing contamination of the gas stream. The metal-to-metal diaphragm seal further enhances leak integrity, a critical factor when dealing with hazardous or expensive specialty gases. This construction allows the regulator to withstand internal vacuums, making it compatible with purging operations necessary for maintaining system purity during cylinder changes.

Stable and Safe Operation

As a two-stage regulator, the 322-69-23-00-00 excels in providing a constant delivery pressure regardless of fluctuations in the inlet pressure as the cylinder empties. This stability is essential for analytical instruments and precise process control. Safety is also paramount in the design; the bonnet features a captured vent port (1/16” FNPT) which allows for the safe piping and venting of hazardous gases in the unlikely event of a diaphragm failure. The large 2-1/2 inch single scale gauges provide clear readability, ensuring operators can monitor system status at a glance.

Versatile Integration

Designed with flexibility in mind, the regulator includes threaded front and rear bonnets, facilitating easy front panel mounting for integrated system setups. With a CGA 350 connection and a delivery range of up to 100 PSI, it is tailored for specific hydrogen and hydrocarbon gas mixtures often found in laboratory and industrial settings. Note that for hazardous gas applications, a Cross Purge Assembly is recommended to ensure effective removal of toxic traces during cylinder swaps.
