OVERVIEW

Reliable Gas Control for Demanding Environments

When your work involves specialty gases, precision and safety are not just options—they are requirements. The Miller Smith 320 Series High Purity Two-Stage Regulator (322-69-23-00-00) delivers professional-grade performance for welders, lab technicians, and industrial operators who require the utmost in reliability. Built to handle the toughest conditions, this regulator features a robust stainless steel construction that resists corrosion, ensuring a long service life even when used with aggressive gases.

Consistent Pressure Delivery

One of the biggest challenges in gas regulation is maintaining a steady flow as your tank pressure drops. The two-stage design of the Miller Smith 320 Series solves this problem by stepping down the pressure in two phases, guaranteeing that your output remains constant from the moment you open a full cylinder until it is nearly empty. This feature is particularly valuable for precision welding, analytical testing, or any application where pressure spikes or drops could ruin a project or damage sensitive equipment.

Built for Safety and Purity

Contamination is the enemy of high-purity applications. That’s why this regulator utilizes a 316 stainless steel filtered seat and a metal-to-metal diaphragm seal to lock out impurities and prevent leaks. For those working with hazardous gases, the captured vent port offers an extra layer of safety, allowing you to pipe potential leaks away from the workspace. The clear, easy-to-read 2-1/2 inch gauges allow for quick checks, so you can focus on the job at hand with confidence.

Miller True Blue Quality

Invest in equipment that stands the test of time. The Miller Smith 320 Series is backed by the reputation of Miller Electric, a leader in the welding and gas equipment industry. With its CGA 350 connection and 100 PSI delivery capability, this regulator is ready to integrate seamlessly into your existing setup. Whether you are setting up a new laboratory station or upgrading your industrial gas delivery system, this regulator provides the durability and precision you need to get the job done right.

FAQ

A two-stage regulator reduces cylinder pressure in two steps, providing a constant delivery pressure regardless of changes in the inlet pressure as the cylinder empties. This is ideal for applications requiring precise and stable flow.

Yes, the Miller Smith 320 Series is constructed with 316 Stainless Steel wetted parts and PCTFE seats, making it highly resistant to corrosion and suitable for use with corrosive gases.

The captured vent port (1/16 inch FNPT) allows for the safe venting of hazardous gases away from the work area in the event of a diaphragm failure, enhancing operator safety.

This specific model (322-69-23-00-00) comes with a CGA 350 inlet connection, which is typically used for hydrogen and certain hydrocarbon gas mixtures.

Yes, the front and rear bonnets are threaded, allowing for front panel mounting in integrated systems or control panels.

This model has a delivery pressure range of 0-100 PSIG, suitable for applications requiring pressures within this specific limit.

For hazardous gas applications, it is highly recommended to use a Cross Purge Assembly with this series to ensure effective purging of gas traces during cylinder changes.

The diaphragm is made of convoluted stainless steel, which provides precise pressure control and maintains a metal-to-metal seal for leak integrity.
