OVERVIEW

Precision Control with Miller Smith 320 Series Stainless Steel Regulator

When your work demands absolute precision and purity, the Miller Smith 320 Series High Purity Two-Stage Regulator delivers. Designed for professionals handling specialty gases, this regulator (Model 320-70-23-00-00) is the ultimate solution for controlling corrosive and non-corrosive gases with confidence. Whether you are operating in a research laboratory, a high-tech manufacturing facility, or a specialized welding environment, the 320 Series ensures that your gas delivery remains stable, clean, and safe.

Unmatched Durability and Purity
Constructed from high-grade 316 stainless steel, this regulator is built to resist the harshest corrosive environments. The stainless steel diaphragm and filtered seat prevent contamination, ensuring that the gas reaching your application is as pure as the gas in the cylinder. The metal-to-metal seal design eliminates the use of elastomers that can degrade or off-gas over time, providing superior leak integrity that you can trust.

Steady Pressure, Every Time
Fluctuating delivery pressure can ruin sensitive experiments or compromise process quality. The Miller Smith 320 Series utilizes a two-stage design that automatically adjusts to the decaying inlet pressure of the gas cylinder. This means you get a consistent flow and pressure from the moment you open the valve until the cylinder is empty, without constant monitoring or readjustment.

Safety First Design
Handling hazardous gases requires equipment that prioritizes safety. This regulator features captured vent ports in the bonnet, allowing you to pipe potential leaks away from the work area safely. It is also designed to withstand vacuum purging, a critical step in changing cylinders safely without introducing impurities. With large, easy-to-read 2-1/2 inch gauges and a standard CGA 350 connection, this regulator combines professional-grade performance with user-friendly features.

Upgrade your gas delivery system with the reliability of Miller Smith. Perfect for applications requiring a delivery range of up to 30 PSIG and compatible with inlet pressures up to 3500 PSIG.

FAQ

A two-stage regulator provides constant delivery pressure regardless of fluctuations in the inlet pressure (cylinder pressure). As the gas in the cylinder is consumed and pressure drops, a two-stage regulator maintains a steady output, whereas a single-stage regulator would require manual adjustment.

Yes, the Miller Smith 320 Series is specifically designed for corrosive applications. It features a 316 Stainless Steel body, diaphragm, and filtered seat, along with PCTFE wetted parts to resist corrosion.

The CGA 350 fitting is a standard connection typically used for flammable gases such as Hydrogen, Carbon Monoxide, Ethylene, and Methane. Always verify your cylinder valve type before purchasing.

This specific model (320-70-23-00-00) has a delivery pressure range of 30" HG (vacuum) to 30 PSIG. It is designed for low-pressure, high-precision applications.

Captured vent ports (1/16" FNPT) located in the bonnet allow users to connect tubing to vent hazardous or toxic gases to a safe location in the event of a diaphragm failure or pressure relief activation.

Yes, the regulator is designed to withstand internal vacuums. This is essential for purging operations during cylinder changes to remove atmospheric air and moisture without damaging the regulator.

The Miller Smith 320-70-23-00-00 is rated for a maximum inlet pressure of 3500 PSIG.

Yes, it includes large 2-1/2 inch easy-to-read single scale gauges for monitoring both inlet (cylinder) pressure and delivery pressure.
