122-0003 - Miller Smith Silverline 2-Stage Regulator, 0-100 PSI, CGA 326

Technical Precision with Miller Smith Silverline Series

The Miller Smith 122-00-03 Silverline Series General Purpose Two-Stage Regulator is engineered for applications requiring absolute precision and constant delivery pressure. Unlike single-stage regulators that show a rise in delivery pressure as the cylinder empties, this two-stage unit reduces the high-pressure gas in two steps. The first stage reduces the inlet pressure to a preset intermediate level, and the second stage reduces it to your specific working pressure. This architecture ensures that the outlet pressure remains steady throughout the life of the cylinder, making it ideal for laboratory, test stand, and precision industrial applications.

Constructed from rugged brass bar stock, the body and bonnet are plated for superior corrosion resistance and longevity. The regulator features a large 1-7/8 inch stainless steel diaphragm which provides exceptional sensitivity to pressure changes, allowing for fine-tuned control within the 0-100 PSI delivery range. The unit is equipped with a CGA 326 inlet connection, typically utilized for specific gas mixtures or Nitrous Oxide, though the series is rated for general inert non-corrosive gases such as Air, Nitrogen, CO2, and Argon. Users should verify cylinder compatibility with the CGA 326 fitting.

Internal reliability is secured by Miller's Sure-Seat technology. A filtered seat prevents particulate matter from entering the high-velocity gas stream, significantly extending the service life of the regulator seat and maintaining gas purity. The regulator includes large, easy-to-read 2-1/2 inch gauges and is tapped for rear panel mounting, offering versatility for various installation setups. With a maximum inlet pressure rating of 3500 PSI, this regulator is a robust solution for demanding gas control tasks.
