621-01060000 - Miller Smith 620 Series Silverline High Purity 2-Stage Regulator CGA 350

Miller Smith 621-01-06-00-00 Silverline High Purity Regulator

The Miller Smith 621-01-06-00-00 is a premium component of the 620 Silverline Series, engineered specifically for non-corrosive specialty gases that demand precise and stable delivery pressure control. This high-purity brass two-stage regulator is designed to maintain a constant outlet pressure regardless of fluctuations in inlet pressure, making it an essential tool for laboratory and high-precision industrial applications. The unit features a CGA 350 connection, making it suitable for gases such as Hydrogen and Methane, with a delivery range of 0-60 PSI.

At the core of this regulator is a unique stainless steel diaphragm that provides maximum accuracy and stable regulation. The construction utilizes a metal-to-metal body-to-diaphragm seal, eliminating the need for elastomeric seals that can outgas or degrade over time, thus ensuring the purity of the gas stream. A 316 stainless steel filter is integrated into the seat to further protect against particulate contamination. The body is machined from brass bar stock and nickel-plated to resist diffusion and maintain a clean aesthetic and functional surface.

Safety and versatility are key aspects of the 621-01-06-00-00. It includes capturable vents in the bonnet (1/16" FNPT) for both stages, allowing for the safe piping of hazardous gases away from the work area 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 in system integration.
