623-01100000 - Miller Smith 620 Silverline High Purity Two-Stage Regulator, CGA 590, 0-250 PSI

Precision Control for Specialty Gas Applications

The Miller Smith 623-01-10-00-00 Silverline High Purity Brass Two-Stage Regulator is engineered for applications demanding the highest levels of stability and cleanliness. Part of the renowned 620 Silverline Series, this regulator is specifically designed for non-corrosive specialty gases, such as Industrial Air, utilizing a CGA 590 inlet connection. The core advantage of this unit lies in its two-stage construction, which provides a constant outlet pressure of 0-250 PSI regardless of fluctuations in the inlet pressure. This feature is critical for analytical processes where pressure drift can compromise results.

Constructed from nickel-plated brass bar stock, the body offers excellent durability and diffusion resistance, while the diaphragm is manufactured from high-grade stainless steel. This material choice, combined with a metal-to-metal body-to-diaphragm seal, ensures that the gas stream remains pure and unaffected by outgassing or elastomeric contamination. The regulator also features a filtered seat with a 316 stainless steel filter, adding an extra layer of protection against particulate contamination that could damage the seat or downstream equipment.

Safety and versatility are built into the design. The bonnet includes a capturable vent (1/16" FNPT), allowing users to pipe away vented gases if necessary—a crucial feature when handling potentially hazardous environments or when the regulator is installed in a confined space. Additionally, the unit is capable of withstanding internal vacuums, making it suitable for rigorous purging operations without compromising the diaphragm's integrity. Threaded front and rear bonnets allow for easy panel mounting, integrating seamlessly into gas management systems and laboratory setups.

Whether used for laboratory analysis, laser gas delivery, or precise industrial process control, the Miller Smith 623 Series delivers the reliability and purity required by professionals. Its robust construction and thoughtful engineering make it a superior choice for managing high-pressure specialty gases.
