321-67240000 - Miller Smith 320 Series High Purity SS Regulator 0-50 PSI CGA 580

Precision Control for High Purity Applications

The Miller Smith 321-67-24-00-00 is a premium component within the 320 Silverline Series, engineered specifically for applications demanding high purity and corrosion resistance. This two-stage regulator is constructed from 316 stainless steel bar stock, ensuring that the gas stream remains uncontaminated by the regulator body itself. It is the ideal choice for analytical laboratories, research facilities, and industrial processes utilizing high-purity inert gases such as Nitrogen, Argon, or Helium via its CGA 580 connection.

Technically, the regulator excels in maintaining a stable delivery pressure of 0-50 PSIG regardless of fluctuations in the inlet pressure, a critical feature as high-pressure cylinders deplete. The internal design features a convoluted stainless steel diaphragm that provides precise sensitivity to pressure changes. A metal-to-metal diaphragm seal eliminates the need for elastomeric seals in the diaphragm assembly, thereby maximizing leak integrity and minimizing the potential for outgassing or contamination. The seat assembly is also filtered with 316 stainless steel to extend service life and protect downstream equipment from particulate matter.

Safety and versatility are integral to the 320 Series design. The unit includes captured vent ports (1/16" FNPT) on the bonnet, allowing for the safe piping away of gases in the unlikely event of a diaphragm failure. The regulator is designed to withstand internal vacuums, making it suitable for rigorous purging operations essential in high-purity environments. Furthermore, the front and rear bonnets are threaded, facilitating easy front panel mounting for integrated system builds. With large 2-1/2" gauges, operators can easily monitor both cylinder and delivery pressures with accuracy.
