Miller Smith Silverline 220 Series Two-Stage High Purity CO2 Regulator, 0-100 PSI

Rugged Reliability with Laboratory Precision

For industrial applications requiring the highest level of gas consistency and equipment durability, the Miller Smith 222-01-02 Silverline Regulator stands out as a premium choice. While built for high-purity applications, its robust construction makes it perfectly at home in demanding shop environments where precision CO2 regulation is required. The regulator features a heavy-duty brass bar stock body, bonnet, and gauges, all plated to resist corrosion and wear, ensuring long-term performance even in tough conditions.

The primary advantage of this unit is its two-stage regulation mechanism. In many welding and industrial processes, maintaining a steady flow rate is essential for quality results. Standard regulators can allow outlet pressure to creep up as the tank empties, requiring constant manual adjustment. The 222-01-02 automatically compensates for dropping cylinder pressure, providing a steady 0-100 PSI delivery from a full tank down to nearly empty. This consistency reduces waste and ensures process uniformity.

Equipped with a CGA 320 inlet for Carbon Dioxide cylinders, this regulator is versatile enough for specialized shielding gas mixtures or calibration tasks. The stainless steel diaphragm offers superior sensitivity compared to rubber diaphragms, allowing for fine-tuning of pressure settings. The large 2-1/2 inch gauges are designed for quick readability, helping operators verify settings at a glance.

Maintenance and safety are also key features. The seat is filtered to prevent debris from entering the high-pressure seat assembly, a common cause of regulator failure. An automatic reseating safety relief valve is built into the body, providing a safeguard against pressure spikes. Whether used for specialized welding setups, laser systems, or calibration stations, the Miller Smith 222-01-02 delivers the reliable, fluctuation-free performance professionals demand.
