322-85240100 - Miller Smith 320 Series High Purity Stainless Steel Two-Stage Regulator, CGA 580, 0-100 PSI

High Purity Precision for Specialty Gases

The Miller Smith 322-85-24-01-00 is a premium component of the 320 Silverline Series, engineered specifically for high purity and specialty gas applications. This two-stage regulator is constructed from 316 stainless steel bar stock, ensuring exceptional resistance to corrosion and maintaining the integrity of the gas stream. It is designed to handle both corrosive and non-corrosive gases, making it a versatile choice for laboratory, analytical, and process control environments where contamination must be eliminated.

Technically, the regulator features a convoluted stainless steel diaphragm that provides precise sensitivity to pressure changes, coupled with a metal-to-metal seal that guarantees maximum leak integrity. The wetted parts, including the 316 stainless steel filtered seat and PCTFE seating material, are selected for their chemical compatibility and durability. The unit is capable of withstanding internal vacuums, a critical feature for effective purging operations during cylinder changeovers. With a CGA 580 inlet, this model is configured for inert gases such as Nitrogen, Argon, and Helium, delivering a stable output pressure of 0-100 PSIG regardless of inlet pressure decay.

Safety and integration are key aspects of the 320 Series design. The bonnet includes captured vent ports (1/16" FNPT) on both stages, allowing for the safe piping of vented gases away from the work area in the rare event of a diaphragm failure. Additionally, the front and rear bonnets are threaded, facilitating easy front panel mounting for system integration. This regulator represents the intersection of safety, durability, and high-precision engineering.
