610-03020000 - Miller Smith 610 Series High Purity CO2 Regulator, 0-25 PSI, CGA 320

Precision Control for High Purity Applications

The Miller Smith 610-03-02-00-00 Silverline High Purity Brass Single Stage Regulator is engineered to meet the rigorous demands of analytical laboratories and specialty gas applications. Designed specifically for non-corrosive gases, this regulator excels in environments where maintaining gas stream purity is critical. The unit features a robust nickel-plated brass bar stock body that offers superior durability while maintaining an economical price point compared to full stainless steel models. Its primary function is to provide accurate, stable pressure regulation for Carbon Dioxide (CO2) systems utilizing a CGA 320 inlet connection.

Advanced Diaphragm Technology

At the heart of the 610 Series is a specially designed stainless steel diaphragm. Unlike elastomeric diaphragms that can absorb or release contaminants (outgassing), the stainless steel construction ensures that the gas stream remains pure and unaffected by the regulator materials. This metal-to-metal seal between the body and the diaphragm eliminates the need for soft seals that could degrade over time or introduce impurities. This design feature is essential for applications such as gas chromatography, emission monitoring systems, and research instrumentation where even trace contamination can compromise results.

Reliability and Safety Features

The regulator is equipped with a 10-micron 316 stainless steel filter located at the seat assembly. This filter traps particulates that may be present in the gas cylinder or piping, preventing damage to the regulator seat and ensuring a long service life. The 610-03-02-00-00 is capable of withstanding an internal vacuum, making it suitable for systems that require purging. For enhanced safety, the bonnet includes a 1/16-inch FNPT port, allowing users to pipe vented gases away from the work area in the event of a diaphragm failure. With a delivery pressure range of 0-25 PSIG and a maximum inlet pressure of 3500 PSIG, this regulator provides precise low-pressure control necessary for sensitive downstream equipment.
