613-40020000 - Miller Smith 610 Series Silverline High Purity CO2 Regulator, 0-250 PSI

Precision High Purity Gas Control

The Miller Smith 613-40-02-00-00 Silverline High Purity Brass Single Stage Regulator is engineered for applications where maintaining the integrity of the gas stream is paramount. Part of the renowned 610 Series Silverline, this regulator is specifically designed to prevent contamination in high purity systems while providing accurate and stable regulation of non-corrosive gases. The core of its performance lies in the specially designed stainless steel diaphragm, which offers superior sensitivity and longevity compared to standard elastomeric diaphragms. This metal-to-metal seal between the body and the diaphragm eliminates the potential for off-gassing or contamination, making it an ideal choice for analytical instrumentation, chromatography, and other sensitive laboratory processes.

Constructed from brass nickel-plated bar stock, the body is both durable and resistant to environmental corrosion. The regulator features a filtered seat mechanism that adds an extra layer of protection for gas stream purity, ensuring that the downstream equipment receives clean, consistent pressure. A 316 stainless steel filter is integrated into the inlet to trap particulates, further safeguarding the internal components and the application itself. With a delivery range of 0-250 PSI and a maximum inlet pressure of 3500 PSI, this unit is robust enough for high-pressure cylinders while delivering precise low-to-mid range pressure control.

Safety and versatility are also key design elements. The bonnet is equipped with a 1/16-inch FNPT port, allowing for the capture and venting of hazardous gases in the unlikely event of a diaphragm failure. For installation flexibility, the regulator includes a threaded bonnet for panel mounting and a body tapped for rear panel mounting, making it easily adaptable to various system configurations. The large 2-1/2 inch single scale gauge provides clear, easy-to-read pressure monitoring, ensuring operators can maintain optimal system performance with a glance.
