OVERVIEW

Reliable Specialty Gas Delivery

When your work demands the highest standards of safety and precision, the Miller Smith 320 Series High Purity Regulator delivers. This model (322-00-31-00-00) is built to handle the toughest jobs, featuring a robust 316 Stainless Steel construction that stands up to corrosive gases that would destroy standard brass regulators. Whether you are working in a laboratory, industrial processing, or specialized manufacturing, this regulator ensures your equipment performs at its peak.

The "Two-Stage" advantage means you get consistent performance from start to finish. Unlike single-stage regulators that can see pressure fluctuations as your tank empties, this Miller Smith regulator maintains a steady 100 PSI output (adjustable) regardless of the remaining cylinder pressure. This stability is crucial for maintaining process quality and avoiding downtime caused by pressure drift.

Designed with the operator in mind, it features large, easy-to-read 2-1/2 inch gauges and a smooth adjustment mechanism. The unit is also panel-mountable, offering flexibility in how you set up your workstation. Safety features like the captured vent port give you peace of mind when working with hazardous materials. Backed by Miller's reputation for quality, this regulator is an investment in long-term reliability and safety for your specialty gas operations.

FAQ

A two-stage regulator reduces the cylinder pressure in two steps, which provides a constant delivery pressure regardless of fluctuations in the inlet pressure as the cylinder empties. This is essential for applications requiring precise and stable flow.

CGA 705 is the standard connection for Ammonia (Anhydrous) and certain other corrosive or specialty gases. Always verify the gas compatibility with the regulator's materials (316 SS and PCTFE).

316 Stainless Steel offers superior corrosion resistance compared to brass or 304 stainless steel, making it suitable for handling corrosive gases and maintaining high purity in the gas stream.

Yes, Miller Smith equipment is typically covered by the Miller True Blue Warranty. Please refer to the specific warranty documentation for the duration and coverage details.

Yes, the front and rear bonnets are threaded, allowing for front panel mounting, which is ideal for fixed installations in laboratories or gas cabinets.

The captured vent port (1/16" FNPT) allows you to pipe any vented gas away to a safe location. This is a critical safety feature when using hazardous or toxic gases, ensuring they are not released into the immediate workspace if the diaphragm fails.

This specific model (322-00-31-00-00) is configured for a delivery pressure range of 0-100 PSI.

Yes, for hazardous gas applications, the manufacturer notes that a Cross Purge Assembly must be used to ensure effective purging of hazardous gas traces during cylinder changes.
