622-20060100 - Miller Smith 620 Silverline High Purity Two-Stage Regulator CGA 350

Precision Control for High Purity Applications

The Miller Smith 622-20-06-01-00 Silverline High Purity Brass Two Stage Regulator is engineered specifically for non-corrosive specialty gas applications requiring the utmost stability and cleanliness. Part of the renowned 620 Silverline Series, this regulator is designed to maintain the integrity of high-purity gases such as Hydrogen and Methane, utilizing a CGA 350 inlet connection. Unlike standard industrial regulators that may utilize elastomeric diaphragms prone to off-gassing and absorption, the 622-20-06-01-00 features a specially designed stainless steel diaphragm. This critical component ensures that the gas stream remains uncontaminated, making it an excellent choice for laboratory, analytical, and process control environments.

The regulator's construction emphasizes a metal-to-metal seal between the body and the diaphragm, eliminating the need for gaskets that could compromise system purity. The body itself is machined from brass bar stock and nickel-plated to provide a robust, diffusion-resistant housing. A filtered seat mechanism further protects the internal components from particulate damage, ensuring a long service life and consistent performance. For safety in hazardous environments, the bonnet includes a capturable vent (1/16" FNPT), allowing for the safe piping of vented gases away from the work area in the unlikely event of a diaphragm failure.

Functionally, the two-stage design is paramount for precision. It compensates for the drop in cylinder pressure as the gas is consumed, providing a steady delivery pressure of up to 100 PSIG without the need for constant manual adjustment. With a maximum inlet pressure rating of 3500 PSIG, this regulator is built to handle high-pressure cylinders with ease. Whether used for gas chromatography, laser mixtures, or emission monitoring systems, the Miller Smith Silverline regulator delivers the reliability and purity demanded by critical industrial processes.
