OVERVIEW

Precision Control for Corrosive and Specialty Gases


The Miller Smith 323-00-22-00-00 High Purity Two-Stage Regulator is a premium solution designed for the rigorous demands of specialty gas delivery. Part of the renowned 320 Silverline Series, this regulator is engineered to handle both corrosive and non-corrosive gases with unmatched reliability. Its construction features a 316 stainless steel bar stock body and a 316 stainless steel filtered seat, ensuring that the gas stream remains pure and the unit resists the damaging effects of harsh chemical environments.



One of the standout features of this model is its two-stage design. Unlike single-stage regulators that may allow delivery pressure to rise as the cylinder pressure falls (the decaying inlet characteristic), this two-stage unit provides a constant, stable delivery pressure throughout the life of the cylinder. This is critical for analytical applications, laboratory settings, and precise industrial processes where pressure fluctuation cannot be tolerated. The regulator is calibrated for a delivery range of 0-250 PSIG and can handle a maximum inlet pressure of 3500 PSIG.



Safety and integrity are paramount in the design. The regulator utilizes a convoluted stainless steel diaphragm with a unique metal-to-metal seal, providing maximum leak integrity—a vital requirement when handling hazardous or expensive gases. Furthermore, the bonnet features captured vent ports (1/16" FNPT) on both stages, allowing users to pipe vented gases away safely in the unlikely event of a diaphragm failure. Equipped with a CGA 330 connection, this regulator is specifically ready for gases requiring this standard stainless steel fitting.



Key Technical Benefits



  • Corrosion Resistance: Wetted parts of 316 SS and PCTFE.

  • Stable Pressure: Two-stage reduction eliminates delivery pressure fluctuation.

  • High Purity: Filtered seat and metal seals prevent contamination.

  • Safety: Captured vent ports for hazardous gas management.
