The Miller Smith 321-66-24-00-00 is a premium high-purity, two-stage regulator from the renowned 320 Silverline Series. Designed specifically for analytical instrumentation, chromatography, and other applications requiring absolute gas purity, this regulator is constructed from high-grade 316 stainless steel. Its corrosion-resistant body and wetted parts ensure compatibility with a wide range of environments, while the PCTFE seat provides a robust seal that maintains gas integrity over an extended service life.
One of the defining features of the 321-66-24-00-00 is its two-stage design. Unlike single-stage regulators that experience a rise in delivery pressure as the cylinder empties (the decaying inlet characteristic), this two-stage unit reduces pressure in two steps. This results in an exceptionally constant delivery pressure of 0-50 PSI, regardless of fluctuations in the inlet pressure from the supply cylinder. This stability is critical for sensitive laboratory equipment where pressure variance can compromise results.
Miller Smith has engineered this regulator with a convoluted stainless steel diaphragm that offers precise pressure control and a metal-to-metal seal. This design eliminates the need for elastomeric seals in the diaphragm assembly, thereby maximizing leak integrity—a crucial factor when handling expensive or sensitive gases. The unit also features a captured vent port (1/16" FNPT) in the bonnet, allowing for the safe piping and venting of gases in the unlikely event of a diaphragm failure. The regulator comes equipped with a CGA 580 inlet connection, suitable for inert gases such as Nitrogen, Argon, and Helium, and features a 1/4" Male NPT outlet with a stainless steel needle valve for fine flow adjustment.
