110-2008 - Miller Smith Silverline 110 Series Regulator 0-30 PSI CGA 540

Technical Overview: Miller Smith 110-20-08 Silverline Regulator

The Miller Smith 110-20-08 is a precision-engineered single-stage regulator from the renowned Silverline Series, designed to provide reliable pressure control for general purpose applications. This unit is specifically configured with a CGA 540 inlet connection, typically associated with oxygen service, although the series itself supports a broad range of inert and non-corrosive gases including Air, Nitrogen, CO2, and Argon. The regulator operates with a delivery range of 0-30 PSIG, making it suitable for applications requiring low-to-moderate pressure outputs, while handling a maximum inlet pressure of 3500 PSIG.

Structurally, the 110-20-08 is built from rugged brass bar stock, ensuring high mechanical strength and resistance to deformation under pressure. To further enhance durability and longevity, the body, bonnet, and gauges are fully plated, offering superior protection against environmental corrosion and wear. A key technical feature of this model is the inclusion of a large 1-7/8 inch diaphragm. This component is critical for maintaining precise control over delivery pressure, smoothing out fluctuations and ensuring consistent flow rates even as cylinder pressure decays.

Internally, the regulator utilizes Miller Smith's Sure-Seat technology. This design incorporates a filtered seat that prevents particulate contamination from entering the high-pressure seating area, a common cause of regulator failure and creep. By filtering the gas stream, the seat's integrity is preserved, significantly extending the service life of the unit. The regulator is also equipped with large 2-1/2 inch single-scale gauges that provide clear, immediate visual feedback on both cylinder and delivery pressures. For integration into fixed systems, the body is tapped to accommodate rear panel mounting.

It is important to note that while this is a high-quality general-purpose regulator, it is not intended for applications requiring extremely precise analytical control or where the inboard diffusion of air or outgassing of elastomeric components could compromise high-purity work. It is an industrial-grade tool designed for robustness and reliability in standard operating environments.
