622-00080000 - Miller Smith Silverline High Purity Two-Stage Regulator, CGA 540, 0-100 PSI

Precision Gas Control for Analytical Applications

The Miller Smith 622-00-08-00-00 Silverline High Purity Brass Two-Stage Regulator is engineered to meet the rigorous demands of analytical laboratories and specialty gas applications. Designed for use with Oxygen (CGA 540), this regulator provides a stable delivery pressure range of 0-100 PSI, making it an essential component for processes requiring unwavering accuracy and gas stream purity. The 620 Series Silverline is distinguished by its robust construction and attention to detail, ensuring that your gas delivery system remains contamination-free and reliable over long periods of use.

At the heart of this regulator is a unique stainless steel diaphragm. Unlike elastomeric diaphragms that can outgas or absorb impurities, the stainless steel construction ensures that the gas stream remains pure, which is critical for high-precision instrumentation. The metal-to-metal seal between the body and the diaphragm further eliminates the need for gaskets that could degrade or leak over time. This design feature not only enhances purity but also improves the regulator's leak integrity, capable of withstanding internal vacuums during purging operations.

The two-stage architecture of the 622-00-08-00-00 is specifically chosen to provide constant outlet pressure. As a high-pressure cylinder empties, the inlet pressure drops significantly. In single-stage regulators, this can cause the outlet pressure to rise (a phenomenon known as the decaying inlet characteristic). The two-stage design compensates for this, delivering a steady flow at the set pressure regardless of cylinder fluctuations. Housed in a nickel-plated brass bar stock body, the regulator is resistant to environmental corrosion and maintains a professional, clean appearance suitable for laboratory settings. Additional safety and maintenance features include a filtered seat to trap particulates and a capturable vent (1/16" FNPT) in the bonnet, allowing for the safe piping away of vented gases if necessary.
