312-00230000 - Miller Smith Silverline 310 Series Stainless Steel Regulator CGA 350

High Purity Stainless Steel Regulation for Specialty Gases

The Miller Smith 312-00-23-00-00 Silverline High Purity Regulator is a premium single-stage pressure control device engineered specifically for the rigorous demands of specialty gas delivery. Part of the renowned 310 Silverline Series, this regulator is constructed almost entirely from 316 stainless steel, ensuring compatibility with corrosive, non-corrosive, and toxic gases where maintaining system purity is paramount. The unit features a CGA 350 connection, making it suitable for flammable gases such as Hydrogen, Methane, and Carbon Monoxide, provided the application aligns with the pressure and flow specifications.

Advanced Construction and Materials

At the core of this regulator is a convoluted stainless steel diaphragm that provides exceptional sensitivity and stable pressure regulation. Unlike rubber or elastomeric diaphragms that can off-gas or degrade when exposed to corrosive media, the stainless steel diaphragm offers a metal-to-metal seal, guaranteeing maximum leak integrity. The seat is manufactured from PCTFE (Polychlorotrifluoroethylene), a material chosen for its chemical resistance and ability to maintain a tight seal over an extended service life, even under high-pressure conditions. The body is machined from 316 stainless steel bar stock, providing a robust housing that resists environmental corrosion and internal chemical attack.

Safety and Versatility

Safety is a critical design element of the 312-00-23-00-00. The bonnet includes a captured vent port (1/16" FNPT), which allows users to pipe vented gases away to a safe location in the rare event of a diaphragm failure—a mandatory feature when handling toxic or flammable gases. The regulator is also designed for versatility in installation, featuring a threaded bonnet for front panel mounting and a tapped body for rear panel mounting. With a maximum inlet pressure of 3500 PSIG and a delivery range up to 100 PSIG, it is well-suited for analytical laboratories, research facilities, and industrial processes requiring high-purity gas streams.
