213-4003 - Miller Smith 210 Silverline High Purity Regulator CGA 326

Precision Control for Analytical Applications

The Miller Smith 213-40-03 Silverline High Purity Analytical Single Stage Regulator is engineered to meet the rigorous demands of laboratory and analytical environments. Designed specifically for non-corrosive specialty gases, this regulator ensures that the integrity of your gas stream is maintained from the cylinder to the point of use. The core of its performance lies in the stainless steel diaphragm, which provides precise pressure control while eliminating the risk of elastomeric contamination often found in standard rubber diaphragms. This makes it an ideal choice for instrument analysis, automotive emissions testing, and biological laboratories where gas purity is paramount.

Constructed from rugged brass bar stock, the 213-40-03 features a fully plated body, bonnet, and gauges. This plating not only enhances the aesthetic appeal but, more importantly, offers superior protection against environmental corrosion and wear. The regulator is equipped with a CGA 326 connection, typically utilized for Nitrous Oxide service, and supports a maximum inlet pressure of 3500 PSI. The delivery pressure range of 0-150 PSI allows for versatile application across various analytical instruments requiring stable intermediate pressures.

Operational safety and longevity are key design elements of the 210 Silverline Series. The unit includes a built-in capturable preset safety relief valve, providing an essential layer of protection against over-pressurization. Furthermore, the filtered seat design plays a critical role in maintaining gas purity by trapping particulates that could otherwise damage the seat or contaminate downstream equipment. This feature significantly extends the service life of the regulator, ensuring reliable performance over time. The large 2-1/2 inch gauges are easy to read, allowing operators to monitor cylinder and delivery pressures with a quick glance. Additionally, the body is tapped for rear panel mounting, offering flexible installation options for custom gas delivery systems and benchtop setups.
