211-2009 - Miller Smith 210 Silverline High Purity Regulator, CGA 580, 0-60 PSI

Uncompromised Purity for Analytical Precision

The Miller Smith 211-20-09 Silverline High Purity Analytical Single Stage Regulator represents the intersection of industrial durability and laboratory precision. Engineered specifically for the control of high-purity, non-corrosive gases, this regulator is an essential component for facilities where gas integrity is non-negotiable. It is widely utilized in sophisticated applications including instrument analysis, gas chromatography, automotive emissions testing, and biological research laboratories. The 210 Silverline Series is distinguished by its material construction; while it utilizes a rugged brass bar stock body, the entire exterior—including the body, bonnet, and gauges—is plated. This plating not only provides an aesthetic finish but offers superior protection against external corrosion and wear, ensuring the device maintains its cleanroom-ready appearance and functionality over time.

At the heart of the 211-20-09 is a stainless steel diaphragm. In the world of high-purity gas delivery, the diaphragm material is critical. Unlike neoprene or rubber diaphragms found in general-purpose welding regulators, a stainless steel diaphragm prevents the phenomenon of off-gassing and diffusion. This ensures that the gas stream remains free from elastomeric contamination, which could otherwise skew analytical results or damage sensitive instruments. Furthermore, the metal diaphragm provides a distinct tactile feedback for precise pressure adjustment, allowing operators to fine-tune delivery pressure within the 0-60 PSI range with exceptional accuracy. The regulator is also designed to withstand vacuums generated during purging operations, a standard procedure in high-purity systems to eliminate atmospheric contaminants before gas flow begins.

Longevity and reliability are ensured through advanced engineering features. The regulator incorporates a filtered seat design, which acts as a first line of defense against particulate contamination. This filter traps microscopic debris that might enter from the cylinder, protecting the seat from scoring and leakage, thereby extending the service life of the unit. The large, 2-1/2 inch single scale gauges are designed for readability, allowing technicians to monitor cylinder and delivery pressure effortlessly. Safety is integrated directly into the design with a built-in capturable preset safety relief valve. This valve protects the regulator and downstream equipment from over-pressurization events and can be piped away if necessary, adding a layer of safety in enclosed environments. With a maximum inlet pressure rating of 3500 PSI and a CGA 580 connection, this regulator is compatible with standard high-pressure cylinders of inert gases such as Nitrogen, Helium, and Argon.

Installation flexibility is another hallmark of the Silverline series. The body is tapped specifically for rear panel mounting, facilitating secure and organized installation in gas cabinets, laboratory benches, or equipment control panels. This feature eliminates the strain on piping connections often caused by unsupported regulators. By choosing the Miller Smith 211-20-09, facilities invest in a device that guarantees the purity of their process gases while offering the ruggedness required for daily operation.
