OVERVIEW

Precision Control for High Purity Applications

When your work demands absolute precision and cleanliness, the Miller Smith 320 Series High Purity Two-Stage Regulator is the professional's choice. Designed for welders, laboratory technicians, and industrial operators who handle specialty gases, this regulator ensures that your gas delivery system does not become the weak link in your process. The body and wetted parts are crafted from 316 stainless steel, which is crucial for preventing contamination and resisting corrosion over years of service. Whether you are performing TIG welding on aerospace alloys or managing gas flow for an analytical instrument, the purity of your gas stream is protected.

The primary advantage of this unit is its two-stage design. In single-stage regulators, the delivery pressure can fluctuate as the tank pressure drops—a phenomenon known as the "decaying inlet characteristic." This Miller Smith regulator eliminates that issue, providing a constant, steady flow of gas from the moment you open the cylinder until it is empty. This stability is vital for maintaining consistent weld bead profiles or accurate analytical readings without constant manual adjustment.

Safety and ease of use are also paramount. The regulator features large, easy-to-read 2-1/2 inch gauges that allow you to monitor tank and delivery pressure at a glance. The CGA 580 connection is standard for inert gases, ensuring compatibility with your existing Argon, Helium, or Nitrogen cylinders. Additionally, the captured vent port adds a layer of safety by allowing you to pipe potential leaks away from the work area. Backed by Miller's reputation for quality, the 320 Series Silverline regulator is an investment in reliability and performance for your most critical gas delivery needs.

FAQ

A two-stage regulator reduces the cylinder pressure in two steps, which provides a constant delivery pressure regardless of fluctuations in the inlet (cylinder) pressure. This is ideal for applications requiring precise flow control.

CGA 580 is the standard connection for inert gases such as Argon, Helium, and Nitrogen. Always verify the gas cylinder label matches the regulator connection.

316 Stainless Steel provides superior corrosion resistance and ensures high purity by preventing off-gassing or particulate contamination from the regulator body itself.

The maximum inlet pressure rating is 3500 PSIG.

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

The captured vent port (1/16" FNPT) allows for the safe piping of gases to a ventilation system in the event of a diaphragm failure, preventing hazardous gas accumulation in the workspace.

Yes, it is designed to withstand internal vacuums, which is necessary during purging operations to remove atmospheric contaminants before use.

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.
