123-8209 - Miller Smith Silverline 2-Stage Inert Gas Regulator, CGA 580, 0-250 PSI

Precision Control with Miller Smith Silverline Technology

The Miller Smith 123-82-09 Silverline Series General Purpose Two Stage Regulator is engineered for environments demanding rigorous pressure stability and gas purity. As part of the renowned 120 Silverline Series, this regulator utilizes a sophisticated two-stage reduction mechanism. By stepping down high-pressure cylinder gas to an intermediate pressure before the final delivery stage, the unit compensates for the characteristic drop in cylinder pressure (decay) that occurs during use. This ensures that the outlet pressure remains constant at the set point of up to 250 PSI, without requiring manual readjustment by the operator.

Constructed from rugged brass bar stock, the body and bonnet are finished with a durable nickel plating. This plating not only provides a professional aesthetic but significantly enhances resistance to corrosion and wear, making it suitable for laboratory and general plant maintenance environments. The internal mechanics feature Miller's proprietary Sure-Seat technology, which incorporates a filtered seat to prevent debris from entering the high-velocity gas stream. This filtration is critical for maintaining gas purity and extending the service life of the regulator components.

The unit is equipped with a CGA 580 inlet connection, making it compatible with standard inert gas cylinders including Argon, Nitrogen, and Helium. The large 1-7/8 inch diaphragm offers high sensitivity for precise pressure control, while the 2-1/2 inch single-scale gauges provide clear, easy-to-read metrics for both cylinder and delivery pressure. With a maximum inlet rating of 3500 PSI, this regulator is ready for modern high-pressure cylinders. The body is also tapped for rear panel mounting, offering flexibility for fixed installations in gas distribution panels or test benches.
