623-20060000 - Miller Smith Silverline 620 Series High Purity 2-Stage Regulator CGA 350

Precision Control for High Purity Gases

The Miller Smith 623-20-06-00-00 Silverline High Purity Brass Two Stage Regulator is engineered for laboratory and industrial applications where gas purity and pressure stability are paramount. Designed as part of the renowned 620 Silverline Series, this regulator is specifically constructed to handle non-corrosive specialty gases such as hydrogen and methane (CGA 350) with exacting precision. Unlike standard industrial regulators, the Silverline series prioritizes the integrity of the gas stream, making it an essential tool for analytical instrumentation, chromatography, and other sensitive processes.

Advanced Contamination Prevention

One of the standout features of this regulator is its stainless steel diaphragm. In high-purity applications, rubber or elastomeric diaphragms can release trace chemicals (off-gassing) or absorb contaminants, compromising the quality of the gas. The Miller Smith 620 Series utilizes a stainless steel diaphragm with a metal-to-metal seal against the body, effectively eliminating these risks. Additionally, a filtered seat is incorporated into the design to trap any particulate matter, ensuring that the gas delivered to your equipment remains as pure as the source.

Stable Two-Stage Performance

Consistency is key in laboratory settings. This unit features a two-stage regulation mechanism. The first stage reduces the high pressure from the cylinder to an intermediate level, while the second stage reduces it to the precise delivery pressure you set (0-250 PSI). This configuration ensures that the outlet pressure remains constant even as the cylinder pressure drops, eliminating the need for frequent adjustments during operation. The nickel-plated brass bar stock body provides a robust housing that resists corrosion and maintains a clean aesthetic suitable for professional environments.

Safety and Versatility

Safety is integrated into every aspect of the design. The regulator includes capturable vents (1/16" FNPT) on the bonnet, allowing users to pipe hazardous or flammable gases away from the work area in the rare event of a diaphragm failure. With a maximum inlet pressure of 3500 PSI and a delivery range up to 250 PSI, this regulator offers the versatility and reliability required for demanding high-purity gas applications.
