OVERVIEW

Rugged Stainless Steel Regulation for Industrial Gases

The Miller Smith 320 Series Silverline Regulator (Model 322-83-24-00-00) sets the standard for durability and performance in harsh industrial environments. Designed for use with inert and specialty gases utilizing a CGA 580 connection, this regulator is built to withstand the demands of heavy-duty usage while maintaining laboratory-grade precision. The body is machined from 316 stainless steel bar stock, providing superior strength and immunity to rust and corrosion, making it an excellent choice for facilities located in coastal areas or corrosive atmospheres.

Consistent Delivery Pressure

Fluctuating delivery pressures can ruin welds, disrupt processes, and damage equipment. The Miller Smith 322-83-24-00-00 utilizes a true two-stage design to eliminate the "decaying inlet characteristic" common in single-stage regulators. This means that as your gas cylinder empties from 3500 PSI down to 500 PSI, your output pressure remains locked at your set point (up to 100 PSIG). This reliability ensures consistent process parameters without the need for constant manual readjustment by the operator.

User-Friendly Features

Operators will appreciate the large, 2-1/2 inch single-scale gauges that are easy to read from a distance, reducing the risk of reading errors. The regulator is also designed for versatility in installation; the front and rear bonnets are threaded, allowing for secure front panel mounting in gas cabinets or control panels. Whether you are managing shield gas for critical welding applications or controlling purge gases for pipe fabrication, this regulator delivers the control and safety you need.

Reliability You Can Trust

Backed by Miller's reputation for quality, this regulator features a PCTFE seat for extended service life and a convoluted stainless steel diaphragm for precise pressure control. The captured vent port adds an extra layer of safety, ensuring that in the unlikely event of a diaphragm failure, gases can be safely vented away from the operator. Invest in the Miller Smith 320 Series for a regulator that combines high-purity performance with industrial toughness.

FAQ

A two-stage regulator reduces the cylinder pressure in two steps, which provides a constant delivery pressure regardless of changes in the inlet (cylinder) pressure. This is essential for applications requiring stable pressure over the life of the cylinder.

The CGA 580 connection is the standard for non-flammable, non-corrosive inert gases such as Argon, Helium, and Nitrogen. Since this regulator is stainless steel, it maintains high purity for these gases.

Yes, the regulator is constructed with a 316 Stainless Steel body and diaphragm, and PCTFE seats, making it highly resistant to corrosion. However, you must ensure the CGA 580 inlet is appropriate for the specific gas mixture, or use an adapter if safe and compliant.

The captured vent port (1/16" FNPT) allows you to connect a tube to pipe vented gases away to a safe location (like a fume hood or scrubber). This is a critical safety feature when handling hazardous or toxic gases to prevent exposure in the event of a diaphragm failure.

This specific high-purity model uses a captured vent design rather than a standard external relief valve, allowing for the containment and safe disposal of vented gases.

This model comes equipped with a 1/4" Stainless Steel Tube Fitting outlet.

While the regulator works without one, the manufacturer notes that a Cross Purge Assembly must be used with this series to ensure effective purging of hazardous gas traces during cylinder changes, protecting both the operator and the equipment.

The regulator is rated for a maximum inlet pressure of 3500 PSIG.
