323-70250000 - Miller Smith 320 Series High Purity 2-Stage Stainless Steel Regulator, CGA 660, 0-250 PSI

Precision Control for Specialty Gases

The Miller Smith 323-70-25-00-00 Two-Stage Regulator represents the gold standard in gas control for demanding industrial and laboratory environments. Built as part of the renowned 320 Silverline Series, this regulator is constructed from high-grade 316 stainless steel, offering exceptional resistance to corrosion. This makes it the ideal choice for controlling corrosive gases as well as high-purity non-corrosive gases where contamination must be strictly avoided. The regulator features large, easy-to-read 2-1/2 inch single scale gauges, allowing operators to monitor cylinder and delivery pressure with a quick glance.

Performance consistency is achieved through its two-stage architecture. Unlike single-stage regulators that may see delivery pressure rise as the cylinder empties, this two-stage model compensates for inlet pressure decay, providing a steady 0-250 PSI output from start to finish. The internal design includes a PCTFE seat and a convoluted stainless steel diaphragm that provides precise pressure control. The metal-to-metal seal at the diaphragm ensures a leak-tight enclosure, critical for maintaining the purity of the gas and the safety of the workspace.

Designed with versatility and safety in mind, the 323-70-25-00-00 features threaded front and rear bonnets, making it suitable for front panel mounting in gas cabinets or control panels. The inclusion of captured vent ports allows for the safe diversion of vented gases, a necessary feature for hazardous gas applications. Note that for hazardous gas traces, a Cross Purge Assembly is recommended to ensure effective purging during cylinder swaps. With its CGA 660 connection and 3500 PSI max inlet rating, this Miller Smith regulator delivers the reliability and durability professionals expect.
