220-0306 - Miller Smith Silverline 220 Series High Purity Two-Stage Regulator CGA 350

Miller Smith Silverline: The Standard for High Purity Gas Control

For professional welders and industrial technicians requiring absolute precision in gas delivery, the Miller Smith 220-03-06 Silverline Regulator stands out as a top-tier solution. While standard regulators are sufficient for general shielding gas, specialized applications—such as laser welding support, laboratory calibration, or precise heating applications—require the stability that only a high-purity, two-stage regulator can provide. This unit is outfitted with a CGA 350 connection, making it compatible with specific fuel gases and high-purity mixtures.

Consistent Pressure Delivery

The 220-03-06 utilizes a sophisticated two-stage reduction mechanism. This allows the regulator to take high inlet pressures of up to 3500 PSIG and step them down to a precise, low-pressure output of 0-15 PSIG. The primary benefit of this design is consistency; you can drain a cylinder from full to nearly empty without having to constantly adjust your regulator settings. This "set it and forget it" reliability is essential for professionals who need to focus on their work, not their equipment settings.

Built for Durability and Precision

Miller has constructed this regulator with a focus on longevity and accuracy. The stainless steel diaphragm offers superior sensitivity compared to rubber alternatives, allowing for minute pressure adjustments. It also resists the memory effect and embrittlement that can plague standard diaphragms over time. The entire assembly—body, bonnet, and gauges—is plated for superior protection against the harsh environments often found in industrial shops. The filtered seat design adds another layer of reliability by preventing debris from scoring the seat, a common cause of regulator creep and failure.

Safety and Ease of Use

Safety is built into the core of the Silverline series. It features an automatic reseating safety relief valve that vents excess pressure if a malfunction occurs, protecting your hoses and downstream equipment. The large 2-1/2 inch gauges are clear and easy to read from a distance, ensuring you always know your tank status and line pressure. Whether you are setting up a specialized TIG welding station requiring ultra-pure gas or managing a test bench, the Miller Smith 220-03-06 delivers the performance and peace of mind associated with the Miller True Blue warranty.
