211-0302 - Miller Smith 210 Series Silverline High Purity Regulator CGA 320

Reliable High Purity Gas Regulation

When your application demands more than just standard industrial grade regulation, the Miller Smith 211-03-02 Silverline Regulator steps up to deliver high-purity performance with industrial-grade durability. This single-stage regulator is part of the renowned 210 Silverline Series, designed for professionals who need precise control over non-corrosive gases without the risk of contamination. It is particularly well-suited for setups requiring a CGA 320 connection, commonly used for CO2, ensuring that your shielding gas or process gas remains pure for optimal results.

Durability is a hallmark of the Miller Smith brand, and this regulator is no exception. It is machined from solid brass bar stock and fully plated—including the body, bonnet, and gauge cases—to resist corrosion and wear in tough shop or plant environments. The large 2-1/2 inch gauges are designed for high visibility, allowing operators to check cylinder and delivery pressure at a glance. Inside, a stainless steel diaphragm replaces standard rubber components, providing a non-contaminating seal that maintains stable pressure even under fluctuating conditions. This metal diaphragm also prevents the inboard diffusion of atmospheric contaminants, ensuring that what comes out of the nozzle is exactly what is in the cylinder.

The 211-03-02 is built to handle a maximum inlet pressure of 3500 PSI and provides a steady delivery pressure up to 50 PSI. It features a filtered seat assembly that protects the internal mechanism from debris, ensuring a long operational life and consistent performance. A built-in capturable safety relief valve adds an extra layer of protection for both the equipment and the operator. Whether you are setting up a specialized welding station, a laser cutting system, or a testing rig, this regulator offers the perfect balance of high-purity precision and rugged construction.
