622-83060000 - Miller Smith Silverline 620 Series High Purity 2-Stage Regulator CGA 350

Precision Control for Specialty Gases

The Miller Smith 622-83-06-00-00 Silverline High Purity Brass Two Stage Regulator is an advanced pressure control device engineered for non-corrosive specialty gases. Part of the renowned 620 Silverline series, this regulator is specifically configured with a CGA 350 connection, making it suitable for gases such as Hydrogen, Methane, and Carbon Monoxide. The unit is designed to accept a maximum inlet pressure of 3500 PSI and delivers a precise, adjustable outlet pressure up to 100 PSI.

High Purity Construction

Purity is paramount in analytical and laboratory applications. This regulator features a nickel-plated brass bar stock body which provides excellent durability and diffusion resistance. Internally, a 316 stainless steel filter protects the seat from particulate contamination, while the stainless steel diaphragm ensures that the gas stream remains uncontaminated by elastomeric components. The metal-to-metal seal between the body and the diaphragm further guarantees the integrity of the gas path, making this unit ideal for high-purity requirements.

Two-Stage Performance

As a two-stage regulator, the 622-83-06-00-00 offers superior performance characteristics compared to single-stage alternatives. It reduces cylinder pressure in two steps, which results in a constant delivery pressure regardless of fluctuations in the inlet pressure. This means that as your gas cylinder drains and pressure drops, the output flow remains steady without requiring manual adjustment. This feature is critical for long-duration processes where stability is non-negotiable.

Safety and Versatility

Safety is integrated into the design with a capturable vent in the bonnet (1/16" FNPT). This allows for the safe piping away of hazardous gases in the unlikely event of a diaphragm failure. The regulator is also capable of withstanding internal vacuums, facilitating effective purging operations before use. With threaded front and rear bonnets, this unit is ready for panel mounting, offering flexibility for system integration.
