612-40100000 - Miller Smith 610 Series Silverline High Purity Regulator CGA 590

Precision Control for High Purity Systems

The Miller Smith 612-40-10-00-00 Silverline High Purity Brass Single Stage Regulator is engineered to meet the rigorous demands of specialty gas delivery systems. Designed specifically for non-corrosive gases requiring high levels of purity, this regulator features a robust brass bar stock body that is nickel-plated to resist corrosion and maintain a clean aesthetic. The core of its precision lies in the stainless steel diaphragm, which ensures stable regulation of delivery pressure and maximum accuracy across its 0-100 PSI range. Unlike standard regulators, the Silverline series utilizes a metal-to-metal seal between the body and the diaphragm, eliminating the need for elastomeric seals that can outgas and contaminate high-purity streams.

Safety and system integrity are paramount in the design of the 612-40-10-00-00. It includes a filtered seat and a 316 stainless steel filter to prevent particulate contamination, ensuring that downstream equipment remains protected. The regulator is also capable of withstanding an internal vacuum, making it suitable for purging cycles often required in high-purity applications. For enhanced safety, particularly when handling potentially hazardous gases, the bonnet is equipped with a 1/16-inch FNPT port, allowing for the capture and venting of gases in the unlikely event of a diaphragm failure. This feature is critical for maintaining a safe working environment in laboratory and industrial settings.

Installation flexibility is a key advantage of the 610 Series. The unit is designed with a threaded bonnet for panel mounting and a body tapped for rear panel mounting, allowing for seamless integration into gas management panels and analytical instrumentation setups. The large 2-1/2 inch single scale gauge provides clear, easy-to-read pressure monitoring. With a maximum inlet pressure rating of 3500 PSI and a CGA 590 connection, this regulator is perfectly suited for industrial air and other compatible specialty gases, delivering reliable performance where contamination control is non-negotiable.
