313-00310000 - Miller Smith Silverline 310 SS Regulator, CGA 705, 0-250 PSIG

Precision Control for High Purity Applications

The Miller Smith 313-00-31-00-00 is a premium single-stage regulator from the Silverline 310 Series, engineered specifically for the rigorous demands of high purity, corrosive, and toxic gas applications. Constructed from 316 stainless steel bar stock, this regulator ensures minimal contamination and maximum resistance to corrosion, making it an essential component for laboratory, research, and industrial specialty gas systems.

At the core of the 310 Series is a specially designed convoluted stainless steel diaphragm. This feature provides superior sensitivity and stable pressure regulation compared to standard flat diaphragms. The metal-to-metal diaphragm seal eliminates the need for elastomeric seals in the gas path, thereby ensuring maximum leak integrity—a critical requirement when handling hazardous media. All wetted parts are manufactured from 316 PCTFE, further reinforcing the unit's suitability for corrosive environments.

Safety and versatility are paramount in the design of the Silverline 310. The bonnet includes a captured vent port (1/16" FNPT), allowing users to pipe vented gases away to a safe location in the event of a diaphragm failure. This is particularly important for systems utilizing toxic or flammable gases. Additionally, the regulator features a 316 stainless steel filtered seat which not only extends the service life of the unit by trapping particulates but also maintains the purity of the gas stream. With a delivery range of 0-250 PSIG and a CGA 705 inlet, this model is tailored for specific high-pressure cylinder applications requiring robust performance.
