220-2003 - Miller Smith Silverline 220 Series High Purity Regulator, 0-15 PSI, CGA 326

Reliable High Purity Gas Regulation

When precision and purity are non-negotiable, the Miller Smith 220-20-03 Silverline Regulator delivers the performance you need. This high-purity, two-stage regulator is designed for professionals who require exacting control over their gas delivery systems. Whether you are managing calibration mixtures or running sensitive analytical equipment, the Silverline 220 Series provides the consistency and reliability synonymous with the Miller Smith name. With a delivery range of 0-15 PSI and a CGA 326 connection, it is tailored for specific high-purity gas applications.

The regulator features a durable construction that stands up to daily use while maintaining the cleanliness required for specialty gases. The body, bonnet, and gauges are plated to resist corrosion and wear, ensuring the unit remains in top condition even in demanding environments. The internal stainless steel diaphragm is a standout feature, offering superior sensitivity and pressure control compared to standard neoprene diaphragms. This ensures that your delivery pressure remains stable and accurate, which is critical for maintaining process integrity.

Two-Stage Performance

One of the primary advantages of this regulator is its two-stage design. In many welding and industrial applications, a single-stage regulator may allow outlet pressure to rise as the cylinder pressure falls—a phenomenon known as the supply pressure effect. The Miller Smith 220-20-03 eliminates this issue, providing a steady flow and constant pressure from a full cylinder down to a nearly empty one. This maximizes gas usage and reduces the need for constant manual adjustments.

User-Friendly Features

Miller Smith has designed this regulator with the user in mind. The large 2-1/2 inch gauges are easy to read at a glance, reducing the risk of reading errors. The unit also comes with a built-in safety relief valve for added peace of mind. Furthermore, the regulator is capable of withstanding vacuum conditions, which is often necessary during system purging to remove contaminants before introducing the process gas. Backed by Miller's reputation for quality, this regulator is a smart investment for any facility requiring high-purity gas control.
