621-03100000 - Miller Smith 620 Series Silverline High Purity Regulator CGA 590

Precision Control for Specialty Gases

The Miller Smith 621-03-10-00-00 Silverline High Purity Brass Two Stage Regulator is engineered for applications demanding the utmost precision and gas purity. Designed specifically for non-corrosive specialty gases, this regulator features a CGA 590 connection, making it suitable for industrial air and specific gas mixtures. As part of the renowned 620 Silverline series, it represents a standard of excellence in gas delivery systems, ensuring that your critical processes receive a stable and contaminant-free flow.

Advanced Two-Stage Regulation

One of the primary advantages of this unit is its two-stage design. Unlike single-stage regulators that may experience a drop in delivery pressure as the cylinder empties, the 621-03-10-00-00 maintains a constant outlet pressure throughout the life of the cylinder. This is achieved by reducing the pressure in two steps, isolating the delivery pressure from the fluctuations of the inlet supply. For laboratory and analytical applications where stability is paramount, this feature eliminates the need for constant manual adjustments.

Uncompromised Purity and Construction

To maintain the integrity of high-purity gases, Miller Smith has constructed this regulator with a stainless steel diaphragm and a metal-to-metal body seal. This design eliminates the use of elastomeric seals in the gas path that could outgas or absorb contaminants. The body is machined from nickel-plated brass bar stock, providing a robust and corrosion-resistant exterior. Additionally, a 316 stainless steel filter is integrated into the seat to trap particulates, further protecting the seat and ensuring the purity of the gas stream. The regulator is also capable of withstanding internal vacuums, making it suitable for purge cycles essential in high-purity setups.

Safety and Versatility

Safety is integrated into the design with capturable vents in the bonnet (1/16" FNPT). This allows for the safe piping away of gases in the unlikely event of a diaphragm failure, a critical feature when working in enclosed environments. With a delivery range of 0-60 PSI and a maximum inlet pressure of 3500 PSI, this regulator is a versatile tool for professionals requiring reliable gas control.
