320-70320000 - Miller Smith 320 Series High Purity 2-Stage Stainless Steel Regulator CGA 590

Industrial Grade Corrosion Resistance

For industrial applications requiring robust performance and uncompromising durability, the Miller Smith 320 Series High Purity Two-Stage Regulator stands out as a top-tier choice. Model 320-70-32-00-00 is constructed to handle the toughest environments, featuring a body and wetted parts made from 316 Stainless Steel and PCTFE. This construction provides superior resistance to corrosion, making it suitable for a wide range of industrial gases, including those that would degrade standard brass regulators.

Operational consistency is key in welding and industrial processing, and the two-stage design of this regulator delivers exactly that. It steps down pressure in two phases, which eliminates the "droop" or delivery pressure rise often seen in single-stage regulators as the supply cylinder empties. This means you get a steady 0-25 PSIG output without constant adjustment. The unit connects via a standard CGA 590 fitting and supports a maximum inlet pressure of 3500 PSIG, accommodating high-pressure cylinders with ease.

The 320 Series is also designed with maintenance and integration in mind. It features front and rear bonnet threads for panel mounting, allowing for clean and organized system setups. The large 2-1/2 inch gauges provide clear visibility of tank and delivery pressures at a glance. Whether you are setting up a laser system, a chemical processing line, or a research station, this Miller Smith regulator provides the reliability, safety, and precision control required for professional operations. Note that for hazardous gas applications, a Cross Purge Assembly is recommended to ensure effective purging during cylinder changes.
