623-83050000 - Miller Smith 620 Silverline Two-Stage Regulator CGA 346 250 PSI

Precision Control for High Purity Applications

The Miller Smith 623-83-05-00-00 Silverline High Purity Brass Two Stage Regulator is engineered for professionals who demand exacting standards in gas delivery. Part of the renowned 620 Silverline series, this regulator is specifically designed for non-corrosive gases where maintaining gas purity and precise pressure control is critical. The unit features a robust nickel-plated brass bar stock body that provides excellent durability while maintaining a clean aesthetic suitable for laboratory and industrial environments.

At the heart of this regulator is a unique stainless steel diaphragm. Unlike elastomeric diaphragms that can outgas or degrade over time, the stainless steel construction ensures that the gas stream remains uncontaminated, making it ideal for analytical applications. The metal-to-metal seal between the body and the diaphragm further enhances the integrity of the unit, minimizing the risk of external leaks. Additionally, a 316 stainless steel filter is integrated into the seat to trap particulates, protecting the internal components and ensuring a long service life.

Operational stability is a key advantage of the two-stage design. As a gas cylinder empties, the inlet pressure drops, which can cause delivery pressure to fluctuate in single-stage regulators. The Miller Smith 623-83-05-00-00 compensates for these changes, providing a constant outlet pressure of up to 250 PSI regardless of cylinder status. This model comes equipped with a CGA 346 connection, suitable for industrial air applications, and features a capturable vent in the bonnet (1/16" FNPT) to allow for the safe piping away of gases in the event of a diaphragm failure.

Whether used in chromatography, emission monitoring, or precise manufacturing processes, this regulator delivers reliable performance. The 2-1/2 inch single scale gauge offers clear readability, and the unit is capable of withstanding internal vacuums during purging operations, adding to its versatility in high-purity systems.
