323-83250000 - Miller Smith 320 Series High Purity Stainless Steel Two-Stage Regulator, CGA 660, 0-250 PSI

High Purity Precision for Corrosive Environments

The Miller Smith 323-83-25-00-00 is a premium component of the 320 Silverline Series, engineered specifically for the rigorous demands of high-purity and corrosive gas applications. Constructed from 316 stainless steel bar stock, this two-stage regulator is designed to maintain the integrity of the gas stream while providing exceptional durability against corrosive media. The unit features a 316 stainless steel filtered seat and a PCTFE seat assembly, ensuring that the gas pathway remains uncontaminated and the regulator service life is maximized.

Technical precision is at the core of the 320 Series. It utilizes a convoluted stainless steel diaphragm that offers superior sensitivity and control over delivery pressure compared to standard elastomeric diaphragms. The metal-to-metal diaphragm seal is a critical feature for high-purity applications, providing a leak-tight seal that prevents atmospheric contamination. This regulator is rated for a delivery range of 0-250 PSIG and is equipped with a CGA 660 connection, making it suitable for specific corrosive gas cylinders. The two-stage architecture ensures that the outlet pressure remains constant regardless of fluctuations in the inlet pressure, a vital characteristic for analytical instrumentation and process control.

Safety and operational versatility are also prioritized. The bonnet includes captured vent ports (1/16" FNPT) on both stages, allowing for the safe piping and venting of hazardous gases in the unlikely event of a diaphragm failure. Furthermore, the design supports internal vacuums, facilitating effective purging operations when used with a cross-purge assembly. This regulator is an essential tool for laboratories, research facilities, and industrial processes requiring uncompromised gas quality and safety.
