OVERVIEW

Industrial Grade Stainless Steel Regulation

When your operation deals with specialty gases and corrosive environments, standard brass regulators simply won't cut it. The Miller Smith 322-70-31-00-00 is a premium Two-Stage Stainless Steel Regulator designed to withstand the rigors of industrial and specialty gas applications. Built with the legendary quality of the Miller Smith Silverline Series, this unit provides the durability and precise control needed for welding, chemical processing, and manufacturing sectors utilizing CGA 705 connections.

Consistent Pressure Delivery

In professional settings, consistency is key. This two-stage regulator excels at providing a steady 0-100 PSI delivery pressure regardless of fluctuations in the inlet pressure. As your gas cylinder empties, ordinary regulators can allow outlet pressure to creep up, potentially damaging downstream equipment or ruining a weld. The 322 series eliminates this issue, maintaining a flat delivery curve up to a maximum inlet pressure of 3500 PSI. This reliability allows operators to focus on the task at hand rather than constantly adjusting regulator settings.

Robust Construction & Safety Features

The 322-70-31-00-00 is built tough. It features a 316 stainless steel body and a convoluted stainless steel diaphragm, offering superior strength and corrosion resistance compared to standard materials. The metal-to-metal diaphragm seal ensures a gas-tight closure, minimizing the risk of leaks. For added safety when working with hazardous gases, the regulator includes captured vent ports on both stages, allowing for the safe piping of vented gases. This feature is essential for maintaining a safe work environment in enclosed spaces.

Versatile Installation

Designed with the user in mind, this regulator features large 2-1/2 inch gauges that are easy to read at a glance. The front and rear bonnets are threaded, facilitating front panel mounting for integrated system setups. Whether you are setting up a laser mix, a purging station, or a chemical feed system, the Miller Smith 322 series offers the flexibility and performance required. Note that for hazardous gas traces, a Cross Purge Assembly is recommended during cylinder changes to ensure effective purging.

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. A single-stage regulator's delivery pressure may fluctuate as the cylinder pressure drops.

CGA 705 is typically used for corrosive gases such as Ammonia, Dimethylamine, and Trimethylamine. Always verify compatibility with your specific gas supplier.

A stainless steel diaphragm prevents contamination of the gas stream and offers superior resistance to corrosion compared to rubber or neoprene diaphragms, making it ideal for high purity and corrosive applications.

The captured vent port (1/16 inch FNPT) allows you to connect a tube to pipe hazardous or toxic gases away to a safe ventilation system in the event of a diaphragm failure or pressure relief activation.

Yes, while it is designed for corrosive environments, its high purity construction makes it excellent for non-corrosive high-purity gases where maintaining gas integrity is critical.

The Miller Smith 322-70-31-00-00 is rated for a maximum inlet pressure of 3500 PSIG.

Yes, Miller Smith regulators typically fall under the Miller True Blue Warranty. Please check the specific warranty documentation for the Silverline series for duration and coverage details.

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