322-70240000 - Miller Smith 320 Series High Purity Stainless Steel Regulator, CGA 580, 0-100 PSI

Precision Control for High Purity Applications

The Miller Smith 322-70-24-00-00 High Purity Two-Stage Regulator is a premium gas control device engineered for the most demanding industrial and laboratory environments. Part of the renowned 320 Silverline Series, this regulator is specifically designed to handle corrosive and non-corrosive gases where maintaining gas stream purity is paramount. Constructed from high-grade 316 stainless steel bar stock, the body and wetted parts offer exceptional resistance to corrosion, making it an ideal choice for specialty gas delivery systems.

One of the standout features of this unit is its two-stage regulation mechanism. Unlike single-stage counterparts, this regulator reduces cylinder pressure in two steps, ensuring that the delivery pressure remains constant even as the inlet pressure drops during cylinder depletion. This is critical for analytical applications where pressure fluctuations can compromise results. The unit features a convoluted stainless steel diaphragm that provides precise sensitivity and control over the 0-100 PSIG delivery range.

Leak integrity is assured through a unique metal-to-metal diaphragm seal, eliminating the need for elastomeric seals that can degrade or outgas over time. This design achieves a high level of leak tightness, essential for handling hazardous or expensive high-purity gases. Additionally, the regulator includes a captured vent port (1/16" FNPT) in the bonnet, allowing users to pipe vented gases away safely in the event of a diaphragm failure. The 316 stainless steel filtered seat further protects the mechanism from particulate contamination, extending the service life of the regulator.

Designed for versatility, the regulator can withstand internal vacuums, making it suitable for purging operations. It comes equipped with large, easy-to-read 2-1/2 inch gauges and is configured with a CGA 580 inlet connection, standard for inert gases like Argon, Nitrogen, and Helium. Whether for analytical instrumentation, process control, or semiconductor manufacturing, the Miller Smith 322-70-24-00-00 delivers reliability and precision.
