312-00200000 - Miller Smith Silverline 310 High Purity SS Regulator 0-100 PSIG CGA 320

Precision Control for High Purity Applications

The Miller Smith 312-00-20-00-00 Silverline High Purity Regulator is a premier solution designed specifically for the rigorous demands of analytical laboratories, semiconductor manufacturing, and chemical processing industries. Part of the esteemed 310 Silverline Series, this single-stage regulator is engineered to prevent contamination in high-purity systems while providing accurate and stable regulation of corrosive, non-corrosive, or toxic gases. The unit features a delivery pressure range of 0-100 PSIG, making it suitable for a wide variety of sensitive applications where precision is non-negotiable.

Advanced Materials and Construction

At the core of this regulator's performance is its robust construction. All wetted parts—those exposed to the flowing media—are manufactured from 316 Stainless Steel and PCTFE (Polychlorotrifluoroethylene). This material selection is critical for resisting chemical attack from corrosive gases, thereby ensuring both the longevity of the device and the purity of the gas stream. The body is machined from 316 stainless steel bar stock, providing a dense, non-porous structure that eliminates the risk of outgassing or absorption common with lesser materials.

Superior Diaphragm Technology

The 312-00-20-00-00 utilizes a specially designed, convoluted stainless steel diaphragm. Unlike rubber or elastomeric diaphragms that can degrade or release particulates, the stainless steel diaphragm offers a metal-to-metal seal against the body. This design feature provides maximum leak integrity—a vital requirement when handling hazardous or toxic gases. The convoluted shape enhances the sensitivity of the regulator, allowing for precise pressure control and rapid response to flow changes, ensuring that downstream equipment receives a stable supply of gas.

Safety and Versatility

Safety is paramount in the design of the Silverline series. The bonnet includes a captured vent port (1/16" FNPT), which allows operators to pipe vented gases away to a safe disposal area in the rare event of a diaphragm failure. This feature is essential for maintaining a safe working environment when using toxic media. Additionally, the regulator is capable of withstanding an internal vacuum, making it compatible with purge cycles necessary for maintaining system purity during cylinder changes. The unit comes equipped with large, 2-1/2 inch single-scale gauges that are easy to read, ensuring operators can monitor system status at a glance.
