610-00070000 - Miller Smith 610 Series High Purity Brass Regulator CGA 510 25 PSI

Technical Overview of the Miller Smith 610 Series Regulator

The Miller Smith 610-00-07-00-00 is a premium single-stage regulator from the Silverline series, engineered specifically for high-purity, non-corrosive gas applications. This unit is designed to maintain the integrity of gas streams in analytical, laboratory, and process control environments where contamination must be minimized. The regulator features a CGA 510 inlet connection, making it compatible with specific fuel gases and specialty gas mixtures requiring this standard fitting, while delivering a precise outlet pressure range of 0-25 PSI.

Construction and Material Specifications

The body of the 610 Series is machined from brass bar stock and finished with nickel plating. This construction method eliminates the porosity issues often associated with forged bodies, ensuring a dense, leak-proof containment vessel suitable for high-purity service. A critical feature of this regulator is its stainless steel diaphragm. Unlike elastomeric diaphragms that can absorb and release contaminants (off-gassing) or degrade over time, the stainless steel diaphragm provides an inert boundary that preserves gas purity. The seal between the body and the diaphragm is a metal-to-metal type, further eliminating the need for gaskets that could introduce impurities.

Performance and Safety Features

Performance stability is achieved through the specialized design of the diaphragm and seat assembly. The regulator includes a filtered seat and a 316 stainless steel filter at the inlet to trap particulates, protecting the seat from damage and ensuring consistent performance. With a maximum inlet pressure rating of 3500 PSI, it is robust enough for high-pressure cylinders. For safety, particularly when used with potentially hazardous gases, the bonnet is threaded and equipped with a 1/16-inch FNPT port. This allows for the connection of a vent line to capture and divert gases in the unlikely event of a diaphragm failure. The unit is equipped with a 2-1/2 inch single scale gauge for easy monitoring of delivery pressure.
