322-68240000 - Miller Smith 320 Series High Purity SS Regulator, CGA 580, 100 PSI Delivery

Precision Control for Specialty Gases

The Miller Smith 322-68-24-00-00 is a premium offering from the 320 Silverline Series, engineered specifically for high-purity and corrosive gas applications. 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. Designed for professionals in laboratory, research, and industrial environments where purity is paramount, this regulator features a PCTFE seat and a stainless steel filter that work together to extend service life and prevent contamination.

Two-Stage Stability

One of the defining features of the 320 Series is its two-stage regulation mechanism. Unlike single-stage regulators that may experience a drop in delivery pressure as the cylinder empties, this unit provides a constant, stable delivery pressure regardless of fluctuations in inlet pressure. This is critical for analytical applications such as chromatography or precise chemical reactions where pressure stability directly impacts results. The convoluted stainless steel diaphragm further enhances this precision, offering sensitive control over the 0-100 PSI delivery range.

Safety and Integrity

Safety is engineered into every aspect of this regulator. It features a unique metal-to-metal diaphragm seal that provides maximum leak integrity, a crucial requirement when handling hazardous or expensive specialty gases. The bonnet includes a captured vent port (1/16" FNPT), allowing users to pipe vented gases away to a safe location in the rare event of a diaphragm failure. Additionally, the regulator is designed to withstand internal vacuums, making it suitable for rigorous purging operations required during cylinder changes to eliminate atmospheric contamination.

Versatile Configuration

Equipped with a CGA 580 inlet, this regulator is compatible with standard inert gas cylinders including Nitrogen, Argon, and Helium. The outlet is fitted with a 1/8" tube stainless steel needle valve, providing fine flow control directly at the regulator. The large 2-1/2" gauges are easy to read, and the unit supports front panel mounting, making it adaptable to various system configurations.
