623-00050000 - Miller Smith 620 Series Silverline 2-Stage Regulator, CGA 346, 0-250 PSI Delivery

High Purity Precision for Specialty Gases

The Miller Smith 623-00-05-00-00 Silverline High Purity Brass Two Stage Regulator is engineered for applications where gas purity and pressure stability are paramount. Designed as part of the renowned 620 Silverline Series, this regulator is specifically configured with a CGA 346 connection, making it the ideal choice for industrial air and breathing air applications requiring delivery pressures up to 250 PSI. The two-stage design is a critical feature for professionals who demand consistency; it automatically compensates for the drop in cylinder pressure as the gas is consumed, ensuring that the outlet pressure remains steady without the need for constant manual adjustment.

Construction quality is at the core of the Silverline series. The body is machined from brass bar stock and finished with nickel plating, providing a robust exterior that resists corrosion and wear in industrial environments. Internally, the regulator features a stainless steel diaphragm. Unlike elastomeric diaphragms that can outgas or absorb contaminants, the stainless steel construction ensures maximum gas stream purity. This is further reinforced by a metal-to-metal seal between the body and the diaphragm, effectively eliminating potential leak paths and ensuring the integrity of the gas supply.

Safety and longevity are also key components of this design. The regulator includes a filtered seat and a 316 stainless steel filter to trap particulates before they can damage the seating surface, significantly extending the service life of the unit. For enhanced safety, the bonnet features a capturable vent (1/16" FNPT), allowing users to pipe away gases in the event of a diaphragm failure, a crucial feature when working in enclosed or sensitive environments. Whether used for analytical instrumentation, laser systems, or high-precision industrial processes, this Miller Smith regulator delivers reliable performance.
