213-4005 - Miller Smith 210 Silverline High Purity Air Regulator CGA 346

High Purity Analytical Control

The Miller Smith 213-40-05 Silverline High Purity Analytical Single Stage Regulator is engineered specifically for applications requiring the utmost cleanliness and precision in gas delivery. Part of the renowned 210 Silverline Series, this regulator is designed to control high purity, non-corrosive gases—specifically Air via its CGA 346 connection—without introducing contaminants into the stream. This makes it an ideal choice for sensitive environments such as biological laboratories, chemical process plants, and automotive emissions testing facilities.

Advanced Construction Materials

Unlike standard industrial regulators that may use elastomeric diaphragms, the 213-40-05 features a high-grade stainless steel diaphragm. This metal-to-metal seal construction is critical for analytical work as it eliminates the risk of off-gassing and inboard diffusion of atmospheric contaminants that can occur with rubber components. The body and bonnet are machined from rugged brass bar stock and then fully plated. This plating not only provides a professional, clean aesthetic suitable for lab environments but also offers superior protection against external corrosion and wear.

Precision and Reliability

This single-stage regulator provides a delivery pressure range of 0-200 PSIG, making it versatile for various analytical instruments. It is equipped with a filtered seat that prevents particulate matter from damaging the seating surface, thereby extending the service life of the unit and maintaining gas purity. The regulator is also designed to withstand vacuums generated during purging operations, a common procedure in high-purity gas handling to ensure line cleanliness. Large, 2-1/2 inch single-scale gauges allow for easy monitoring of both inlet and delivery pressures.

Safety and Mounting

Safety is paramount in high-pressure gas handling. The Miller Smith 213-40-05 includes a built-in capturable preset safety relief valve to protect downstream equipment from over-pressurization. For installation flexibility, the body is tapped to accommodate rear panel mounting, allowing for integration into gas management panels or instrument benches.
