313-00000000 - Miller Smith 310 Series Silverline Stainless Steel Regulator 0-250 PSIG

Precision Control for High Purity Applications

The Miller Smith 313-00-00-00-00 Silverline High Purity Regulator is an elite component designed for the rigorous demands of specialty gas delivery. Engineered within the 310 Silverline Series, this single-stage regulator is specifically constructed to maintain the integrity of high-purity systems while providing accurate regulation of corrosive, non-corrosive, or toxic gases. The core of its design features a 316 stainless steel bar stock body, ensuring robust resistance against chemical attack and environmental corrosion.

Technically, the regulator excels through its use of a 316 stainless steel filtered seat. This component is critical for added gas stream purity and significantly extends the service life of the unit by preventing particulate damage. The diaphragm is a convoluted stainless steel type, engineered to provide maximum accuracy and stable regulation of delivery pressure, even as cylinder pressure decays. The metal-to-metal diaphragm seal is a standout feature, offering maximum leak integrity—a non-negotiable requirement when handling hazardous or expensive high-purity media.

Safety and integration are paramount in the 313-00-00-00-00 design. It includes a captured vent port (1/16" FNPT) located in the bonnet, which allows for the safe piping and venting of hazardous gases in the unlikely event of a diaphragm failure. For corrosive applications, all wetted parts are constructed of 316 PCTFE, ensuring compatibility with aggressive media. The unit is versatile in mounting, with a bonnet threaded for front panel installation and a body tapped for rear panel mounting. It comes equipped with large, easy-to-read 2-1/2" single scale gauges and utilizes 1/4" FNPT connections for both inlet and outlet, allowing for flexible integration into custom gas manifolds and systems.
