310-00230000 - Miller Smith 310 Series High Purity Stainless Steel Regulator, 0-25 PSIG, CGA 350

Technical Overview of the Miller Smith 310 Silverline Regulator

The Miller Smith 310-00-23-00-00 is a premium Single Stage High Purity Regulator designed specifically for analytical and process applications where gas purity and corrosion resistance are paramount. Part of the renowned Silverline series, this regulator is engineered to handle corrosive, non-corrosive, and toxic gases with a high degree of precision and safety. The unit features a delivery pressure range of 0-25 PSIG and is equipped with a CGA 350 inlet connection, making it suitable for gases such as Hydrogen and Methane in high-purity grades.

Construction integrity is central to the 310 Series design. The body is machined from 316 stainless steel bar stock, ensuring robust resistance to chemical attack. Internally, the regulator utilizes a 316 stainless steel filtered seat which not only aids in maintaining gas stream purity but also significantly extends the service life of the component by preventing particulate damage. For corrosive applications, all wetted parts are constructed from 316 PCTFE, a material chosen for its chemical inertness and mechanical stability.

A critical feature for high-purity environments is the diaphragm assembly. This model employs a specially designed, convoluted stainless steel diaphragm that provides exceptional sensitivity and stable regulation of delivery pressure, even as cylinder pressure decays. The diaphragm seal is metal-to-metal, eliminating the use of O-rings or gaskets that could introduce contaminants or leak over time. This design ensures maximum leak integrity, capable of withstanding internal vacuum during purging cycles. Furthermore, the bonnet includes a captured 1/16-inch FNPT vent port, allowing for the safe piping of vented gases away from the work area in the event of a diaphragm failure, a mandatory safety feature for hazardous gas systems.

Installation flexibility is provided via a threaded bonnet for front panel mounting and a tapped body for rear panel mounting. The regulator is fitted with large, 2-1/2 inch single scale gauges that are easy to read, ensuring operators can monitor system status at a glance. With a maximum inlet pressure rating of 3500 PSIG, this regulator is a definitive solution for laboratories and industrial facilities requiring uncompromising gas control.
