623-01080000 - Miller Smith 620 Silverline High Purity Oxygen Regulator 250 PSI

Precision Control for High Purity Applications

The Miller Smith 623-01-08-00-00 Silverline High Purity Brass Two Stage Regulator is an exemplary piece of engineering designed for the rigorous demands of specialty gas delivery. Part of the renowned 620 Silverline series, this regulator is specifically constructed to handle non-corrosive gases where maintaining gas purity and precise pressure control is paramount. The unit features a robust nickel-plated brass bar stock body, which not only provides a professional aesthetic but ensures long-lasting durability against environmental factors.

At the heart of this regulator is a unique stainless steel diaphragm. Unlike elastomeric diaphragms that can off-gas or absorb contaminants, the stainless steel construction ensures that the purity of the gas stream remains uncompromised. This is further enhanced by a filtered seat design and a metal-to-metal seal between the body and the diaphragm, virtually eliminating the risk of external leakage or internal contamination. For applications requiring strict safety protocols, the bonnet includes a capturable vent (1/16" FNPT), allowing users to pipe potential vent gases away to a safe location in the unlikely event of a diaphragm failure.

Functionally, the two-stage design is a critical advantage for analytical and process applications. It provides a constant outlet pressure of 0-250 PSI regardless of fluctuations in the inlet pressure as the supply cylinder drains. This stability allows researchers and technicians to focus on their work without constantly adjusting regulator settings. With a maximum inlet pressure rating of 3500 PSI and a standard CGA 540 connection, this regulator is perfectly suited for high-pressure oxygen cylinders used in laboratories, chromatography, and precision manufacturing.
