611-03060000 - Miller Smith 610 Series High Purity Brass Regulator CGA 350

Precision Control for High Purity Applications

The Miller Smith 611-03-06-00-00 Silverline High Purity Brass Single Stage Regulator is a pinnacle of engineering designed specifically for the rigorous demands of analytical and specialty gas delivery systems. In environments where gas purity is paramount, such as gas chromatography, emission monitoring, or research laboratories, the integrity of the regulator is critical. This 610 Series regulator addresses these needs with a construction that minimizes contamination risks. The heart of the unit is a stainless steel diaphragm, which not only provides a non-reactive surface for the gas stream but also ensures stable and accurate pressure regulation. Unlike rubber or elastomer diaphragms that can absorb and release contaminants (off-gassing), the stainless steel construction maintains the chemical integrity of the gas flowing through it.

Further enhancing its suitability for high-purity applications is the metal-to-metal seal between the body and the diaphragm. This design eliminates the need for gaskets that could degrade or contaminate the system over time. The regulator also features a filtered seat and a 316 stainless steel filter, providing a robust defense against particulate contamination that could compromise sensitive downstream equipment. The body is machined from brass bar stock and finished with nickel plating, offering a durable, corrosion-resistant exterior that maintains a clean appearance suitable for laboratory environments.

Safety and versatility are also key components of the 611-03-06-00-00. The bonnet includes a 1/16-inch FNPT port, a critical feature for venting hazardous gases safely away from the workspace in the unlikely event of a diaphragm failure. This capturable vent capability is essential when working with flammable or toxic gases often associated with CGA 350 connections, such as hydrogen or methane. Additionally, the regulator is designed to withstand internal vacuum, making it compatible with purge cycles necessary for maintaining system purity during cylinder changeovers. With a delivery range of 0-60 PSI and a maximum inlet pressure of 3500 PSI, this regulator provides reliable performance for a wide range of specialty gas applications.
