623-00070000 - Miller Smith 620 Series Silverline High Purity Regulator, CGA 510, 0-250 PSI

Precision Control for High Purity Applications

The Miller Smith 623-00-07-00-00 is a premium offering from the 620 Silverline Series, specifically engineered for the regulation of non-corrosive specialty gases requiring absolute precision. Designed with a high-purity brass architecture, this two-stage regulator is the ideal solution for laboratory environments, chromatography, and emission monitoring systems where gas stream integrity is paramount. The unit features a CGA 510 connection, making it suitable for specific high-purity fuel gases and hydrocarbons that utilize this standard fitting.

Advanced Two-Stage Design

Stability is the cornerstone of the 620 Series. Unlike single-stage counterparts that may experience outlet pressure fluctuations as the supply cylinder empties (decay), this two-stage regulator provides a constant, unwavering delivery pressure throughout the life of the cylinder. This is achieved by reducing the pressure in two steps, isolating the final delivery pressure from the variations of the inlet source. With a delivery range of 0-250 PSI and a maximum inlet capacity of 3500 PSI, it offers versatile performance for a wide range of analytical applications.

Uncompromised Material Quality

To maintain the purity of the gas stream, Miller Smith has constructed this regulator with a nickel-plated brass bar stock body and a 316 stainless steel filter. Crucially, the diaphragm is made from stainless steel, utilizing a metal-to-metal seal with the body. This design eliminates the need for elastomeric seals in the gas path, which can be a source of contamination through outgassing or absorption. The result is a regulator that maintains the high fidelity of your specialty gases.

Safety and Versatility

Safety features are integrated directly into the design, including capturable vents in the bonnet (1/16" FNPT) which allow 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, making it suitable for purging operations essential in high-purity setups. Threaded front and rear bonnets facilitate easy panel mounting, ensuring this regulator fits seamlessly into your existing gas distribution infrastructure.
