310-66220000 - Miller Smith 310 Series Silverline High Purity Stainless Steel Regulator, CGA 330, 0-25 PSIG

Precision Control for Corrosive and Specialty Gases

The Miller Smith 310-66-22-00-00 Silverline High Purity Regulator is a premium single-stage pressure control device engineered specifically for the rigorous demands of analytical, pharmaceutical, and chemical processing environments. Designed to handle corrosive, non-corrosive, and toxic gases, this regulator is built around a 316 stainless steel bar stock body that ensures minimal particulate generation and maximum resistance to chemical attack. The unit features a CGA 330 inlet connection, making it suitable for specific corrosive gas services such as Hydrogen Sulfide, Carbonyl Sulfide, and other compatible media requiring high-integrity stainless steel fittings.

At the core of the 310 Series is a convoluted stainless steel diaphragm. Unlike flat diaphragms, this convoluted design provides superior sensitivity and stable pressure regulation across the delivery range of 0-25 PSIG. The diaphragm utilizes a metal-to-metal seal with the body, eliminating the need for elastomeric seals that could degrade over time or introduce impurities into the gas stream. This construction is critical for maintaining the integrity of high-purity systems where even trace contamination can compromise process results. The regulator also incorporates a 316 PCTFE seat, chosen for its mechanical strength and chemical resistance, further enhancing the unit's durability and service life.

Safety is paramount when handling hazardous gases. The Miller Smith 310 Series addresses this with a captured vent port located in the bonnet. This 1/16-inch FNPT port allows operators to pipe vented gases away to a safe disposal system in the unlikely event of a diaphragm failure, preventing exposure to toxic fumes. Additionally, the regulator is equipped with a diffusion-resistant, packless diaphragm outlet valve (needle valve) with a 1/4-inch MNPT connection, providing precise flow control while maintaining system purity. With a maximum inlet pressure rating of 3500 PSIG and large, easy-to-read 2-1/2 inch gauges, this regulator delivers the reliability and performance required for critical gas delivery applications.
