622-83090000 - Miller Smith Silverline 620 Series High Purity 2-Stage Regulator CGA 580

Precision Control for Specialty Gas Applications

The Miller Smith 622-83-09-00-00 Silverline High Purity Brass Two Stage Regulator is engineered for professionals who demand uncompromising accuracy and purity in their gas delivery systems. Part of the renowned 620 Silverline Series, this regulator is specifically designed for non-corrosive gases, making it an excellent choice for laboratory, analytical, and high-precision industrial applications using inert gases like Argon, Nitrogen, or Helium (CGA 580).

Unmatched Purity and Integrity

Gas purity is paramount in analytical processes, and the 622-83-09-00-00 delivers with a specially designed stainless steel diaphragm. Unlike elastomeric diaphragms that can off-gas or degrade, the stainless steel construction ensures that the gas stream remains uncontaminated. The metal-to-metal seal between the body and the diaphragm further enhances leak integrity, eliminating the need for O-rings that could introduce impurities. A 316 stainless steel filter is integrated into the seat assembly to trap particulates, ensuring added gas stream purity and prolonging the life of the regulator.

Stable Two-Stage Performance

Fluctuations in cylinder pressure can wreak havoc on sensitive equipment. This two-stage regulator solves that problem by reducing pressure in two steps, providing a constant outlet pressure regardless of changes in the inlet pressure as the cylinder empties. With a delivery range of 0-100 PSI and a maximum inlet capacity of 3500 PSI, it offers robust performance for a wide range of applications. The unit also features capturable vents (1/16" FNPT) on the bonnet, allowing for the safe piping away of gases in the unlikely event of a diaphragm failure, a critical safety feature for enclosed environments.

Robust Construction

Built from nickel-plated brass bar stock, the body is both durable and aesthetically professional. The regulator includes easy-to-read 2-1/2" single scale gauges and is capable of withstanding internal vacuums during purging operations, making it a versatile tool for complex gas management systems.
