111-2005 - Miller Smith Silverline 110 Series Single Stage Regulator, CGA 346, 0-60 PSI

Technical Overview of the Miller Smith 111-20-05

The Miller Smith 111-20-05 is a robust single-stage regulator from the Silverline 110 Series, engineered specifically for general purpose applications involving inert and non-corrosive gases such as Air, Nitrogen, CO2, and Argon. This unit is configured with a CGA 346 inlet connection, making it particularly suitable for compressed air systems found in industrial environments. The regulator is designed to handle a maximum inlet pressure of 3500 PSIG and provides a delivery pressure range of 0-60 PSIG, suitable for a wide variety of pneumatic tools and shielding gas applications where extremely precise low-pressure control is not critical.

Structurally, the 111-20-05 is built for longevity. It features a body machined from brass bar stock, which is then plated—along with the bonnet and gauges—to offer superior protection against corrosion and external wear. Internal components include a large 1-7/8 inch diaphragm which facilitates responsive pressure control. A key technical feature is the inclusion of Sure-Seat technology; the filtered seat design prevents debris from entering the seating area, thereby maintaining gas stream purity and significantly extending the operational life of the regulator. The unit also supports rear panel mounting, as the body is tapped to accommodate such installations, providing versatility for system integrators.

Specifications and Performance

This Silverline regulator prioritizes reliability in non-critical flow applications. While not intended for high-purity analytical work where inboard diffusion is a concern, it excels in standard industrial MRO tasks. The 2-1/2 inch single scale gauges provide clear readouts of cylinder and delivery pressure. The use of a filtered seat is a critical preventative maintenance feature, reducing the likelihood of seat failure due to particulate contamination often found in industrial gas cylinders.
