620-02090000 - Miller Smith 620 Series Silverline High Purity 2-Stage Regulator CGA 580

Precision Control for Analytical Applications

The Miller Smith 620-02-09-00-00 Silverline High Purity Brass Two Stage Regulator is engineered to meet the rigorous demands of analytical laboratories and specialty gas applications. Designed specifically for non-corrosive gases, this regulator ensures that gas purity is maintained from the cylinder to the point of use. The core of its performance lies in its two-stage construction, which provides a constant delivery pressure regardless of fluctuations in the inlet pressure. This is critical in chromatography, emission analysis, and other research environments where pressure stability directly impacts data accuracy.

Constructed from nickel-plated brass bar stock, the body offers superior durability and resistance to diffusion, ensuring that the integrity of the gas stream is preserved. The regulator features a unique 316 stainless steel diaphragm that creates a metal-to-metal seal with the body. This design eliminates the outgassing and contamination often associated with elastomeric diaphragms, making it a top choice for high-purity requirements. Additionally, the seat is filtered to prevent particulate contamination, further protecting downstream equipment and extending the service life of the regulator itself.

Safety and versatility are also key components of the 620 Series. The bonnet includes capturable vent ports (1/16" FNPT) on both stages, allowing for the safe piping of vented gases away from the work area in the event of a diaphragm failure. The unit is also capable of withstanding internal vacuums, making it suitable for purging operations essential in maintaining system purity. With a delivery range of 0-25 PSI and a CGA 580 connection, this regulator is perfectly suited for inert gases such as Nitrogen, Argon, and Helium used in sensitive instrumentation.
