111-2010 - Miller Smith Silverline 110 Series Single Stage Regulator CGA 590

Technical Overview of the Miller Smith 111-20-10

The Miller Smith 111-20-10 is a distinguished member of the Silverline 110 Series, engineered specifically for general purpose applications involving inert and non-corrosive gases. This single-stage regulator is designed to handle a variety of gases including Air, Nitrogen, CO2, and Argon, utilizing a CGA 590 inlet connection. The unit is rated for a maximum inlet pressure of 3500 PSI and provides a delivery pressure range of 0-60 PSI, making it suitable for a wide array of industrial tasks where extremely precise low-pressure control is not the primary requirement, but reliability is paramount.

At the core of this regulator's performance is a large 1-7/8 inch diaphragm. This component is critical for maintaining stable delivery pressure even as cylinder pressure decays. The diaphragm's size allows for greater sensitivity compared to smaller compact regulators, ensuring that flow remains consistent during operation. The regulator also features large, easy-to-read 2-1/2 inch single scale gauges, which allow operators to monitor cylinder and delivery pressure at a glance. The body of the regulator is tapped, facilitating rear panel mounting for integrated system setups.

Construction quality is a hallmark of the Miller Smith brand. The 111-20-10 is built from rugged brass bar stock, offering superior strength compared to forged or die-cast alternatives. To further enhance durability, the body, bonnet, and gauges are plated. This plating offers significant protection against environmental corrosion and physical wear, extending the operational lifespan of the unit in harsh shop environments. The internal mechanism includes a filtered seat, which is essential for maintaining gas stream purity and protecting the seating surface from particulate damage.

The regulator incorporates Miller's Sure-Seat technology. This design innovation protects the seat from end-of-service-life failures and ensures consistent performance over time. While this unit is a general-purpose regulator, its robust build quality and thoughtful engineering features like the filtered seat and plated exterior make it a premium choice for facilities requiring dependable gas control for industrial air and inert gas mixtures utilizing the CGA 590 standard.
