OVERVIEW

Reliable Stainless Steel Gas Control

For professional welders, laboratory technicians, and industrial operators demanding the highest level of consistency, the Miller Smith 320 Series Two-Stage Regulator delivers. This specific model (321-00-24-00-00) is configured for a 0-50 PSI delivery range, offering fine-tuned control for shielding gases or process applications. The two-stage design is a "set it and forget it" solution; it steps down the high cylinder pressure in two phases, ensuring that your output pressure remains rock-steady from a full cylinder down to an empty one.

Durability is a key advantage of this unit. Constructed with a 316 stainless steel body and diaphragm, it resists corrosion and wear far better than standard brass regulators. This makes it ideal for harsh industrial environments or applications involving specialty gases that might react with other metals. The large 2-1/2 inch gauges are easy to read at a glance, helping you monitor tank levels and line pressure efficiently. The regulator also features front and rear bonnet threads, allowing for panel mounting if you are integrating it into a fixed gas distribution system.

Whether you are TIG welding exotic alloys requiring ultra-pure argon or managing a laboratory gas manifold, the leak-tight integrity of the metal-to-metal seal provides peace of mind. The inclusion of a captured vent port adds an extra layer of safety, ensuring that any potential gas release can be managed and directed away from the workspace. Invest in the Miller Smith 320 Series for a regulator that combines heavy-duty industrial construction with laboratory-grade precision.

FAQ

This specific model (321-00-24-00-00) is calibrated for a delivery pressure range of 0-50 PSIG.

CGA 580 is the standard connection for inert gases such as Argon, Helium, and Nitrogen.

A two-stage regulator provides constant delivery pressure regardless of fluctuations in the inlet (cylinder) pressure, eliminating the need to readjust pressure as the tank empties.

Yes, the 316 stainless steel construction and PCTFE seats are designed for corrosive resistance. However, you must ensure the CGA 580 fitting is appropriate for your specific gas mixture, or use an adapter if safe to do so.

The regulator features a 1/4" FNPT (Female National Pipe Thread) outlet connection.

Yes, it includes a captured vent port (1/16" FNPT) in the bonnet to allow for safe venting of hazardous gases in the event of a diaphragm failure.

Yes, the front and rear bonnets are threaded to accommodate front panel mounting.

The diaphragm is made of convoluted stainless steel, providing a metal-to-metal seal for high leak integrity.
