622-83050000 - Miller Smith Silverline 2-Stage High Purity Air Regulator, 0-100 PSI, CGA 346

Precision Control for Analytical Applications

The Miller Smith 622-83-05-00-00 Silverline High Purity Brass Two Stage Regulator is engineered for applications demanding the highest levels of gas purity and pressure stability. Part of the renowned 620 Silverline Series, this regulator is specifically designed for non-corrosive gases, such as high-purity air, where maintaining the integrity of the gas stream is critical. It features a CGA 346 inlet connection and provides a delivery pressure range of 0-100 PSIG.

Advanced Diaphragm Technology

At the core of this regulator is a unique stainless steel diaphragm. Unlike elastomeric diaphragms that can absorb and release contaminants (off-gassing), the stainless steel construction ensures zero contamination of the gas stream. This makes it an ideal choice for gas chromatography, emission monitoring systems, and other analytical laboratory setups. The metal-to-metal seal between the body and the diaphragm further enhances leak integrity, ensuring that atmospheric contaminants do not enter the system.

Stable Two-Stage Performance

As a two-stage regulator, the 622-83-05-00-00 reduces cylinder pressure in two steps, providing a constant delivery pressure regardless of fluctuations in the inlet pressure. This means that as your gas cylinder empties, the output pressure remains rock-steady, eliminating the need for frequent manual adjustments. The unit is constructed from nickel-plated brass bar stock, offering durability and resistance to environmental corrosion while maintaining a clean, professional appearance.

Safety and Versatility

Safety is paramount in high-pressure gas handling. This model includes captured 1/16" FNPT vent ports on the bonnet, allowing for the safe piping away of gases in the unlikely event of a diaphragm failure. It is also designed to withstand internal vacuums, making it suitable for purging operations. With threaded bonnets for panel mounting and a 316 stainless steel filter to protect the seat, this regulator is a robust solution for sophisticated gas delivery systems.
