622-00060000 - Miller Smith Silverline 620 Series High Purity 2-Stage Regulator CGA 350

Precision Control for Analytical Applications

The Miller Smith 622-00-06-00-00 Silverline High Purity Brass Two Stage Regulator is engineered to meet the rigorous demands of analytical laboratories and specialty gas applications. Designed specifically for non-corrosive gases such as hydrogen and methane (CGA 350), this regulator ensures the integrity of your gas stream through advanced materials and construction. At its core lies a unique stainless steel diaphragm that provides a metal-to-metal seal with the body, effectively eliminating the risk of elastomeric outgassing or atmospheric contamination. This feature is critical for applications where gas purity must be maintained from the cylinder to the instrument.

Stability is paramount in precision work, and the two-stage design of the 620 Series delivers constant outlet pressure regardless of fluctuations in inlet pressure. As the gas cylinder empties, single-stage regulators typically experience a rise in delivery pressure; however, this two-stage unit compensates automatically, providing a steady 0-100 PSI output without requiring operator intervention. The unit is machined from nickel-plated brass bar stock, offering a robust and aesthetically professional finish that resists environmental corrosion.

Safety and versatility are also key components of the design. The regulator features capturable vents (1/16" FNPT) on the bonnet, allowing users to pipe vented gases away to a safe location—a mandatory requirement when handling flammable or hazardous gases like hydrogen. Furthermore, the regulator is built to withstand internal vacuums, making it compatible with purge cycles often required in high-purity systems. With a maximum inlet pressure of 3500 PSI and a filtered seat to prevent debris damage, this Miller Smith regulator represents a reliable investment for any facility requiring precise gas management.
