OVERVIEW

Reliable Gas Delivery for Specialty Welding and Labs

When your work demands absolute precision and cleanliness, the Miller Smith 320 Series High Purity Stainless Steel Regulator stands in a league of its own. This model (320-67-24-00-00) is specifically built for professionals who deal with specialty gases, including inert gases like Argon, Helium, and Nitrogen, via its CGA 580 connection. Whether you are setting up a high-end TIG welding station requiring ultra-pure shielding gas or managing a laboratory gas manifold, this regulator delivers the consistency you need.

Constructed from high-grade 316 Stainless Steel, this regulator is virtually immune to corrosion, making it suitable for harsh environments and corrosive gas service. The two-stage design is a game-changer for long-duration processes; it steps down the pressure in two intervals, ensuring that your output pressure remains rock-steady at your set point (0-25 PSI) even as your tank pressure drops from 3500 PSI down to empty. You won't have to constantly adjust the knob to compensate for the "end-of-tank" pressure spike common in cheaper regulators.

Visibility and ease of use are also key. The regulator is equipped with large, 2-1/2 inch single-scale gauges that are easy to read at a glance. The 1/4" Male NPT outlet provides a standard connection point for various fittings and hoses. Backed by Miller's reputation for quality, this Silverline series regulator offers peace of mind with features like a captured vent port for safety and a metal-to-metal diaphragm seal for leak-proof performance. Invest in the 320 Series for equipment that lasts longer and performs better.

FAQ

A two-stage regulator reduces cylinder pressure in two steps, providing a constant delivery pressure regardless of changes in the inlet (cylinder) pressure. A single-stage regulator's delivery pressure may fluctuate as the cylinder empties.

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

CGA 580 is the standard connection for inert gases such as Argon, Helium, and Nitrogen. Since this is a stainless steel regulator, it is often used for high-purity versions of these gases.

This specific model (320-67-24-00-00) has a delivery pressure range of 0-25 PSIG, allowing for precise low-pressure control.

It features a captured vent port in the bonnet (1/16" FNPT) which allows for the safe venting of hazardous gases in the event of a diaphragm failure, rather than a standard open relief valve.

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

Yes, 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.

The wetted parts (parts that come into contact with the gas) are made of 316 Stainless Steel and PCTFE.
