613-00080000 - Miller Smith Silverline High Purity Oxygen Regulator, 0-250 PSI, CGA 540

Precision Gas Control for Analytical Applications

The Miller Smith 613-00-08-00-00 Silverline High Purity Brass Single Stage Regulator is engineered to meet the rigorous demands of analytical laboratories and specialty gas delivery systems. Part of the renowned 610 Series Silverline, this regulator is designed specifically to prevent contamination in high-purity systems while providing accurate and stable regulation of non-corrosive gases like oxygen. The core of its precision lies in the specially designed stainless steel diaphragm, which offers superior sensitivity compared to standard elastomeric diaphragms, ensuring that delivery pressure remains constant even as cylinder pressure decays.

Constructed from brass nickel-plated bar stock, the body of the regulator is both durable and resistant to environmental corrosion. A key feature for high-purity applications 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, thereby removing potential sources of outgassing and leakage that could compromise the purity of the gas. Additionally, a 316 stainless steel filter is integrated into the inlet to trap particulates, protecting the seat and ensuring the integrity of the gas stream.

Safety and versatility are also paramount in the 613-00-08-00-00 design. The bonnet features a 1/16-inch FNPT port, allowing for the capture and venting of gases in the unlikely event of a diaphragm failure—a critical safety feature for laboratory environments. For installation flexibility, the regulator includes a threaded bonnet and a tapped body, making it fully compatible with panel mounting configurations. With a maximum inlet pressure of 3500 PSIG and a delivery range of 0-250 PSIG, this regulator provides the control and reliability essential for sophisticated instrumentation and process control.
