614-40090000 - Miller Smith 610 Series Silverline High Purity Regulator, CGA 580, 0-500 PSI

High Purity Regulation for Critical Applications

The Miller Smith 614-40-09-00-00 is a distinguished member of the 610 Series Silverline family, engineered specifically for the precise control of non-corrosive gases in high purity systems. This single-stage regulator is constructed from brass nickel-plated bar stock, offering a robust yet chemically resistant housing suitable for laboratory, analytical, and specialty industrial environments. The core of its performance lies in the stainless steel diaphragm, which provides a non-contaminating pressure boundary, unlike elastomeric diaphragms that can introduce impurities into the gas stream.

Designed with a metal-to-metal seal between the body and the diaphragm, this regulator ensures exceptional leak integrity, a critical requirement for maintaining the purity of the downstream process. The unit features a delivery pressure range of 0-500 PSI, making it versatile for various high-pressure delivery requirements. To further protect the system and the regulator seat, a 316 stainless steel filter is integrated into the inlet, effectively trapping particulates that could compromise performance. The regulator is equipped with a CGA 580 inlet connection, standard for inert gases such as Argon, Nitrogen, and Helium.

Safety and adaptability are also key features of the 614-40-09-00-00. The bonnet includes a 1/16-inch FNPT port, allowing for a capturable vent connection to safely pipe away gases in the unlikely event of a diaphragm failure. The regulator is also designed for panel mounting, with a threaded bonnet and tapped body, facilitating seamless integration into gas management panels and control systems. With a maximum inlet pressure rating of 3500 PSI, this regulator is compatible with high-pressure cylinders, ensuring reliable operation across a wide range of supply conditions.
