610-00090000 - Miller Smith 610 Series High Purity Single Stage Regulator CGA 580

Precision High Purity Gas Control

The Miller Smith 610-00-09-00-00 Silverline High Purity Brass Single Stage Regulator is engineered for applications where gas purity and precise pressure control are paramount. Designed specifically for non-corrosive specialty gases, this regulator is a staple in laboratories, research facilities, and analytical environments. The core of its performance lies in its construction; unlike standard industrial regulators that may use elastomeric diaphragms, the 610 Series features a high-grade stainless steel diaphragm. This choice of material is critical for preventing the absorption and release of contaminants (outgassing), ensuring that the gas delivered to your instrumentation remains as pure as the source.

The regulator operates with a maximum inlet pressure of 3500 PSI and provides a precise delivery pressure range of 0-25 PSI, making it ideal for low-pressure applications such as gas chromatography or blanketing. The body is machined from brass bar stock and finished with nickel plating, offering a clean, durable surface that resists environmental corrosion. A key feature for high-purity systems is the metal-to-metal seal between the body and the diaphragm. This design eliminates the need for O-rings or gaskets in the gas stream, which are common sources of contamination in lesser regulators.

Safety and versatility are also built into the design. The bonnet includes a 1/16" FNPT port, allowing users to capture and vent gases away safely in the unlikely event of a diaphragm failure. Additionally, the regulator is designed to withstand internal vacuum, facilitating effective purging cycles to clear lines before use. With a standard CGA 580 inlet connection, it is compatible with inert gases like Nitrogen, Argon, and Helium. The outlet is a 1/4" FNPT connection, providing flexibility for various fitting requirements.
