614-01020000 - Miller Smith 610 Series Silverline High Purity Regulator, CGA 320, 0-500 PSI

Precision Control for High Purity Applications

The Miller Smith 614-01-02-00-00 is a premium component within the 610 Series Silverline family, engineered specifically for high purity gas systems where contamination control and precise regulation are paramount. This single-stage regulator is constructed from brass nickel-plated bar stock, offering a robust yet clean solution for managing non-corrosive gases. The core of its performance lies in the specially designed stainless steel diaphragm. Unlike elastomeric diaphragms that can absorb or release contaminants, the stainless steel construction ensures zero off-gassing and maintains the integrity of the gas stream. This makes it an ideal choice for laboratory settings, analytical instrumentation, and specialized industrial processes requiring strict purity standards.

A key feature of this regulator is its metal-to-metal body-to-diaphragm seal, which eliminates the need for O-rings that could degrade over time or introduce impurities. The unit is equipped with a 316 stainless steel filter and a filtered seat, providing a double layer of protection against particulate contamination that could compromise downstream equipment. With a delivery pressure range of 0-500 PSI and a maximum inlet pressure of 3500 PSI, it offers versatile performance for various high-pressure supply cylinders. The CGA 320 connection is specifically standard for Carbon Dioxide (CO2) service, making this regulator a top-tier choice for high-purity CO2 applications.

Safety and adaptability are also built into the design. The bonnet features a 1/16" 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, ensuring it can be seamlessly integrated into gas management panels or benchtop setups. The 2-1/2 inch single scale gauge provides clear, easy-to-read pressure monitoring, ensuring operators can maintain precise control over their system parameters at all times.
