322-83240000 - Miller Smith 320 Series High Purity 2-Stage Stainless Steel Regulator, CGA 580, 0-100 PSI

Precision Control for High Purity Applications

The Miller Smith 322-83-24-00-00 High Purity Two-Stage Regulator is a premier solution for laboratories and industrial facilities requiring uncompromising gas purity and pressure stability. Part of the esteemed 320 Silverline Series, this regulator is engineered specifically for analytical instrumentation, process control, and specialty gas delivery where contamination must be eliminated. The unit features a robust 316 stainless steel bar stock body and a 316 stainless steel filtered seat, ensuring that the gas stream remains free from particulate contamination while offering exceptional resistance to corrosive media.

Advanced Two-Stage Design

Unlike single-stage alternatives, this two-stage regulator provides a constant delivery pressure of 0-100 PSIG regardless of fluctuations in the cylinder's inlet pressure. As the cylinder drains, the intermediate stage compensates for the drop, delivering a steady flow critical for sensitive chromatography and spectrometric applications. The convoluted stainless steel diaphragm offers superior sensitivity, allowing for precise adjustments and stable flow rates even at lower pressure settings.

Safety and Integrity

Safety is paramount when handling specialty gases. The Miller Smith 322-83-24-00-00 incorporates a unique metal-to-metal diaphragm seal, providing maximum leak integrity to prevent atmospheric contamination or gas escape. For applications involving hazardous or toxic gases, the regulator includes captured vent ports (1/16" FNPT) in the bonnet, allowing users to pipe vented gases away to a safe disposal system. This regulator is also designed to withstand internal vacuums, making it compatible with rigorous purging operations required during cylinder changeovers.
