OVERVIEW

Precision Control for Inert Gas Applications

The Miller Smith 123-20-09 Silverline Series General Purpose Two-Stage Regulator is engineered for professionals who demand stability and precision in gas delivery. Designed specifically for inert and non-corrosive gases such as Air, Nitrogen, Carbon Dioxide (CO2), and Argon, this regulator is a staple in laboratories, testing facilities, and general plant maintenance operations. Its primary advantage lies in its two-stage construction, which reduces cylinder pressure in two steps. This mechanism ensures that the delivery pressure remains constant even as the cylinder pressure decays, eliminating the need for frequent manual adjustments during long-duration processes.

Robust Construction and Purity

Built to withstand the rigors of industrial environments while maintaining laboratory-grade performance, the 123-20-09 features a rugged brass bar stock body. To further enhance durability and aesthetics, the body, bonnet, and gauges are fully plated, offering superior protection against corrosion and wear. Inside, Miller's proprietary Sure-Seat technology works in tandem with a filtered seat design. This filtration system is critical for maintaining gas stream purity, preventing debris from damaging the seating surface, and significantly extending the service life of the regulator.

User-Centric Design Features

Operational efficiency is at the forefront of the Silverline Series design. The regulator is equipped with a large 1-7/8 inch diaphragm, which provides exceptional sensitivity and precise control over the 0-250 PSI delivery range. Operators can easily monitor system status thanks to the large, 2-1/2 inch single-scale gauges that are designed for readability. Additionally, the body is tapped for rear panel mounting, offering versatility for fixed installations in gas manifolds or test benches. With a maximum inlet pressure of 3500 PSI and a CGA 580 connection, this regulator is the reliable choice for managing high-pressure inert gas sources.

FAQ

A two-stage regulator reduces cylinder pressure in two steps, which allows it to maintain a constant delivery pressure even as the cylinder pressure drops. A single-stage regulator may show a slight increase in delivery pressure as the cylinder empties, requiring manual adjustment.

This regulator is equipped with a CGA 580 connection and is designed for inert and non-corrosive gases, including Argon, Nitrogen, Helium, and Air. It is also suitable for CO2 if the cylinder has a matching fitting or adapter.

No, this regulator has a CGA 580 connection which is specific to inert gases. Oxygen cylinders use CGA 540. Never use an adapter to force a connection for Oxygen service due to safety risks.

The Miller Smith 123-20-09 has a delivery pressure range of 0-250 PSI.

Yes, the body of the regulator is tapped to accommodate rear panel mounting, making it suitable for fixed installations and test benches.

This product is covered by the Miller True Blue Warranty. Please refer to the specific warranty documentation for the duration and coverage details.

It is a general-purpose regulator with a filtered seat. While suitable for general lab use and high-grade industrial gases, it is not recommended for ultra-high purity applications where inboard diffusion of air is a critical concern.
