622-40100000 - Miller Smith 620 Series Silverline High Purity Regulator, CGA 590, 0-100 PSI

Precision Control for High Purity Applications

The Miller Smith 622-40-10-00-00 Silverline High Purity Brass Two-Stage Regulator is engineered for professionals who demand exacting standards in gas delivery. Part of the renowned 620 Silverline Series, this regulator is specifically designed for non-corrosive specialty gases requiring precise and stable delivery pressure control. The unit features a robust two-stage mechanism that provides a constant outlet pressure of 0-100 PSI, regardless of fluctuations in the inlet pressure from the supply cylinder. This makes it an ideal choice for laboratory settings, analytical instrumentation, and industrial processes where consistency is critical.

Advanced Material Construction

At the heart of this regulator is a unique, specially designed stainless steel diaphragm. Unlike elastomeric diaphragms that can absorb or release contaminants, the stainless steel construction ensures maximum accuracy and maintains the purity of the gas stream. The regulator utilizes a metal-to-metal body-to-diaphragm seal, eliminating the need for O-rings that could potentially outgas or degrade over time. The body itself is machined from brass bar stock and finished with a high-quality nickel plating, providing a diffusion-resistant barrier and a clean, professional aesthetic suitable for high-tech environments.

Safety and Versatility

Safety is paramount in high-purity gas handling. The Miller Smith 620 Series includes captured 1/16" FNPT vent ports on the bonnet for both stages. This feature allows for the safe piping and venting of hazardous gases in the unlikely event of a diaphragm failure. Additionally, the regulator is capable of withstanding internal vacuums, making it suitable for purging operations without risking damage to the internal components. A 316 stainless steel filter is integrated into the inlet to protect the filtered seat from particulate damage, further extending the service life of the unit. With threaded front and rear bonnets, this regulator is also ready for panel mounting, offering flexibility in system integration.
