210-2009 - Miller Smith 210 Series Silverline High Purity Regulator CGA 580

Precision Control for Analytical Applications

The Miller Smith 210-20-09 Silverline High Purity Analytical Single Stage Regulator is engineered specifically for environments where gas purity and precise control are non-negotiable. Designed for use with non-corrosive gases in analytical instrumentation, this regulator is a staple in biological laboratories, automotive emission testing facilities, and chemical process plants. The core of its performance lies in the stainless steel diaphragm, which provides a non-contaminating surface for the gas stream while offering superior sensitivity to pressure changes compared to standard rubber or neoprene diaphragms.

One of the critical challenges in high-purity gas delivery is preventing inboard diffusion of atmospheric contaminants. The 210 Series addresses this with a rugged brass bar stock construction that is fully plated, including the body, bonnet, and gauges. This plating not only enhances the aesthetic but, more importantly, provides a barrier against corrosion and external contamination. The regulator is also designed to withstand vacuums generated during purging operations, a common procedure in high-purity setups to ensure lines are clear of impurities before gas flow begins.

The 210-20-09 model is configured with a CGA 580 inlet, making it suitable for inert gases such as Nitrogen, Argon, and Helium. It delivers a precise pressure range of 0-15 PSIG, ideal for sensitive instruments that require low-pressure feeds. The unit features a filtered seat which adds another layer of protection for the gas stream and significantly extends the service life of the regulator by preventing particulate damage. With large 2-1/2 inch single scale gauges, operators can easily monitor tank and delivery pressures with accuracy.
