The Miller Smith 312-70-23-00-00 Silverline High Purity Regulator is a premium single-stage device engineered for the most demanding gas delivery applications. Part of the renowned 310 Silverline Series, this regulator is specifically designed to prevent contamination in high-purity systems while providing accurate and stable regulation of corrosive, non-corrosive, or toxic gases. Its robust construction features a body machined from 316 stainless steel bar stock, ensuring exceptional durability and resistance to harsh chemical environments.
At the heart of this regulator is a specially designed convoluted stainless steel diaphragm. This component is critical for achieving maximum accuracy and maintaining stable delivery pressure, even as cylinder pressure decays. The metal-to-metal diaphragm seal offers superior leak integrity, a non-negotiable requirement when handling hazardous or expensive specialty gases. Furthermore, all wetted parts—those exposed to the flowing media—are constructed from 316 stainless steel and PCTFE (Polychlorotrifluoroethylene), making this unit highly resistant to corrosion and suitable for a wide range of industrial and laboratory applications.
Safety and longevity are paramount in the design of the 312-70-23-00-00. A 316 stainless steel filtered seat is integrated to protect the seating mechanism from particulate contamination, thereby extending the service life of the regulator and ensuring the purity of the gas stream. For applications involving hazardous gases, the regulator includes a captured vent port (1/16" FNPT) located in the bonnet. This feature allows for the safe piping and venting of gases in the unlikely event of a diaphragm failure. Additionally, the regulator is versatile in its installation options, featuring a threaded bonnet for front panel mounting and a tapped body for rear panel mounting.
The unit comes equipped with large, 2-1/2 inch single-scale gauges that are easy to read, allowing operators to monitor inlet and delivery pressures with a quick glance. With a delivery range of 0-100 PSIG and a maximum inlet pressure of 3500 PSIG, this regulator is a reliable choice for professionals requiring precise control over their gas delivery systems. Note that for hazardous gas applications, a Cross Purge Assembly is recommended to ensure effective purging during cylinder changes.
