110-8209 - Miller Smith Silverline 110 Series Inert Gas Regulator, 0-30 PSI, CGA 580

Technical Overview of the Miller Smith 110-82-09

The Miller Smith 110-82-09 is a distinguished member of the Silverline Series, engineered specifically for general-purpose control of inert and non-corrosive gases. This single-stage regulator is optimized for applications requiring a delivery pressure range of 0-30 PSIG, making it suitable for low-pressure purging, blanketing, and pneumatic testing. The unit connects via a standard CGA 580 inlet, compatible with Argon, Nitrogen, Helium, and mixed inert gases. Its internal architecture is defined by a large 1-7/8 inch diaphragm, which provides a high degree of sensitivity and stable pressure regulation despite fluctuations in cylinder pressure.

Constructed from rugged brass bar stock, the body is designed to withstand the rigors of industrial environments. A key technical differentiator is the nickel plating applied to the body, bonnet, and gauges, which offers superior resistance to environmental corrosion compared to raw brass. The regulator incorporates Miller's proprietary Sure-Seat technology, which utilizes a filtered seat design. This filtration system is critical for preventing particulate contamination from entering the high-pressure seat area, a common cause of regulator failure and creep. The seat assembly is engineered for extended service life and maintains gas stream purity, essential for sensitive downstream applications.

The 110-82-09 is rated for a maximum inlet pressure of 3500 PSIG, accommodating modern high-pressure cylinders. The outlet is equipped with a standard 9/16"-18 Right Hand connection (B-size), ensuring compatibility with standard inert gas hoses. The unit also features 2-1/2 inch single-scale gauges that provide clear, legible readings of both cylinder and delivery pressure. For system integrators, the body is tapped to facilitate rear panel mounting, allowing for versatile installation in gas distribution panels or machinery.
