323-67240000 - Miller Smith 320 Series High Purity Stainless Steel Two-Stage Regulator, CGA 580, 0-250 PSI

Precision Control for High Purity Applications

The Miller Smith 323-67-24-00-00 is a premium component of the 320 Silverline Series, engineered specifically for the rigorous demands of high purity and corrosive gas regulation. This two-stage regulator is constructed from 316 stainless steel bar stock, ensuring exceptional resistance to corrosion and maintaining the integrity of the gas stream. It is designed to provide a constant delivery pressure ranging from 0 to 250 PSI, regardless of fluctuations in the inlet pressure, making it an ideal choice for analytical laboratories, research facilities, and industrial processes requiring stable gas flow.

Advanced Materials and Construction

At the core of this regulator is a convoluted stainless steel diaphragm that offers precise sensitivity and control. The metal-to-metal diaphragm seal eliminates the need for elastomeric seals that can outgas or degrade over time, thereby ensuring maximum leak integrity (1 x 10^-9 cc/sec Helium). The seat assembly utilizes PCTFE material combined with a 316 stainless steel filter, which not only extends the service life of the regulator but also protects the downstream process from particulate contamination. This robust construction allows the unit to withstand internal vacuums, facilitating effective purging operations essential for maintaining high purity standards.

Safety and Versatility

Safety is paramount in the design of the 320 Series. The regulator features captured vent ports (1/16" FNPT) on the bonnet, allowing for the safe piping and venting of hazardous or toxic gases in the unlikely event of a diaphragm failure. The unit is equipped with large, easy-to-read 2-1/2 inch single scale gauges that provide clear visual confirmation of cylinder and delivery pressures. With a CGA 580 inlet connection, this model is suitable for a wide range of inert and non-corrosive gases such as Nitrogen, Argon, and Helium, as well as compatible corrosive mixtures. The threaded front and rear bonnets also offer flexibility for panel mounting installations.
