622-02060000 - Miller Smith Silverline 620 Series 2-Stage High Purity Regulator CGA 350

Precision Control for High Purity Applications

The Miller Smith 622-02-06-00-00 Silverline High Purity Brass Two Stage Regulator is engineered for the rigorous demands of laboratory and specialty gas environments. Designed specifically for non-corrosive gases such as Hydrogen and Methane (utilizing the CGA 350 connection), this regulator ensures that the purity of your gas stream is maintained from the cylinder to the application point. The core of this performance lies in its stainless steel diaphragm, which provides a non-contaminating surface and superior sensitivity compared to standard elastomeric diaphragms. This construction allows for a metal-to-metal seal between the body and the diaphragm, eliminating the potential for off-gassing or absorption associated with rubber components.

Stability is paramount in analytical applications. As a two-stage regulator, the 622-02-06-00-00 drops the cylinder pressure in two steps, resulting in a constant delivery pressure of 0-100 PSI regardless of fluctuations in the inlet pressure as the supply cylinder empties. This feature is critical for chromatography, process control, and other applications where pressure drift can invalidate results. The unit is rated for a maximum inlet pressure of 3500 PSI, accommodating high-pressure cylinders with ease.

Safety and durability are also key design elements. The body is machined from brass bar stock and nickel-plated to resist environmental corrosion and maintain a clean appearance. For hazardous gas applications, the regulator features capturable vents (1/16" FNPT) on the bonnet, allowing potential leaks to be piped away safely. Additionally, the regulator is designed to withstand internal vacuums, making it suitable for purge cycles essential in high-purity systems. A 316 stainless steel filter protects the seat from particulate damage, ensuring a long service life and reliable shut-off.
