623-01000100 - Miller Smith 620 Series Silverline High Purity 2-Stage Regulator 250 PSI

Precision Control for Specialty Gases

The Miller Smith 623-01-00-01-00 Silverline High Purity Brass Two Stage Regulator is engineered for professionals who demand exacting standards in gas delivery. Designed specifically for non-corrosive specialty gases, this regulator ensures that your downstream processes receive a consistent and pure flow of gas, regardless of fluctuations in the supply cylinder pressure. The core of this unit is its unique stainless steel diaphragm, which provides superior sensitivity and accuracy compared to standard elastomeric diaphragms. This metal-to-metal seal between the body and the diaphragm eliminates the risk of off-gassing or contamination, making it an ideal choice for analytical instrumentation and high-purity applications.

Constructed from nickel-plated brass bar stock, the body of the regulator offers both durability and a clean, professional appearance. The two-stage mechanism is critical for applications requiring stable pressure over long periods; as the inlet pressure drops from a full cylinder, the outlet pressure remains rock-steady at your set point, up to 250 PSI. This model features 1/4" FNPT connections on both the inlet and outlet, allowing for versatile integration into custom manifolds, panels, or line systems. Additionally, the bonnet includes a capturable vent (1/16" FNPT), a crucial safety feature that allows for the piping away of hazardous gases in the unlikely event of a diaphragm failure.

Reliability is further enhanced by a 316 stainless steel filter located at the seat, preventing particulate matter from damaging the internal components. Whether you are setting up a laboratory gas system or a precise industrial process, the Miller Smith 620 Series delivers the performance and purity required for critical operations.
