OVERVIEW

Reliable Gas Regulation for Industrial Environments

Welders Supply is proud to offer the Miller Smith 320 Series Silverline High Purity Regulator, a top-tier solution for professionals who demand durability and accuracy. The 322-00-00-00-00 model is a robust two-stage regulator designed to deliver consistent pressure ranging from 0 to 100 PSI. Unlike standard brass regulators, this unit is crafted from high-grade 316 stainless steel. This material choice not only provides a sleek, professional appearance but, more importantly, offers superior resistance to environmental corrosion and chemical attack. Whether you are working in a petrochemical plant, a pharmaceutical facility, or a high-tech welding shop using specialty shielding gases, this regulator is built to last.

The two-stage mechanism is a game-changer for long-duration tasks. It steps down the high-pressure cylinder gas in two phases, ensuring that the output pressure remains rock-steady from the moment you open a full cylinder until it is nearly empty. This eliminates the need for constant manual adjustments and ensures process consistency. The large, 2-1/2 inch gauges are easy to read at a glance, featuring a single scale for clarity. The regulator also features front and rear bonnet threads, allowing for panel mounting if your setup requires a fixed installation.

Flexibility is built into the design with 1/4" FNPT inlet and outlet ports. This universal porting allows you to adapt the regulator to virtually any gas cylinder or pipeline system by simply installing the appropriate fittings. Whether you are managing corrosive gases or simply need a high-purity solution for sensitive welding applications, the Miller Smith 320 Series delivers the performance you expect from a leader in gas equipment. Backed by Miller's reputation for quality, this regulator is an investment in safety, efficiency, and precision.

FAQ

This specific model (322-00-00-00-00) has a delivery pressure range of 0-100 PSIG.

Yes, the regulator is constructed with a 316 stainless steel body and diaphragm, along with PCTFE seats, making it highly resistant to corrosive gases.

Both the inlet and outlet ports are 1/4" FNPT (Female National Pipe Thread), allowing for custom fitting installation.

It features captured vent ports (1/16" FNPT) in the bonnet which allow for the safe venting of hazardous gases if the diaphragm fails.

A two-stage regulator provides constant delivery pressure regardless of fluctuations in the inlet (cylinder) pressure, ensuring stable flow throughout the life of the cylinder.

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

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

No, this model comes with 1/4" FNPT ports. You must install the appropriate CGA fitting or tube fitting for your specific application.
