612-03060000 - Miller Smith 610 Series High Purity Regulator CGA 350 0-100 PSI

Precision Control for High Purity Applications

The Miller Smith 612-03-06-00-00 Silverline High Purity Brass Single Stage Regulator is engineered to meet the rigorous demands of specialty gas delivery systems. Designed specifically for use with CGA 350 compatible gases—such as Hydrogen, Methane, and Carbon Monoxide—this regulator ensures that the purity of your gas stream is maintained from the cylinder to the point of use. In analytical laboratories, laser applications, and process control environments, even microscopic contamination can compromise results. The 610 Series addresses this with a filtered seat and a 316 stainless steel filter, which work in tandem to trap particulates and protect the internal seating mechanism.

At the heart of this regulator is a stainless steel diaphragm. Unlike elastomeric diaphragms used in standard industrial regulators, the stainless steel construction prevents off-gassing and absorption of atmospheric contaminants. This creates a reliable metal-to-metal seal between the body and the diaphragm, ensuring a leak-tight enclosure that preserves the integrity of high-purity gases (up to Grade 5.0 or higher depending on system cleanliness). The regulator is also capable of withstanding an internal vacuum, making it compatible with purge cycles that are essential for removing atmospheric air before introducing flammable or reactive gases.

Safety and durability are woven into the design. The body is machined from brass bar stock and finished with nickel plating, offering the substantial weight and thermal stability of brass with the enhanced corrosion resistance of nickel. For applications involving hazardous or flammable gases, the threaded bonnet features a capturable vent (1/16" FNPT). This allows safety engineers to pipe any potential diaphragm failure discharge away from the immediate work area, a critical feature for installations in enclosed cabinets or confined spaces. With a delivery range of 0-100 PSI and a maximum inlet of 3500 PSI, this single-stage regulator provides stable, accurate pressure control for critical operations.
