223-0109 - Miller Smith 220 Series Silverline Two-Stage High Purity Regulator CGA 580

Precision Control for Analytical Applications

The Miller Smith 223-01-09 Silverline High Purity Analytical Two Stage Regulator is engineered to meet the rigorous demands of laboratory and analytical environments. Designed specifically for non-corrosive, high-purity gases, this regulator ensures that your sensitive instrumentation receives a stable and contaminant-free gas supply. Whether you are managing carrier gases for gas chromatography or handling precise calibration mixtures, the 223-01-09 delivers the consistency required for accurate results.

At the heart of this regulator is a stainless steel diaphragm, which provides superior sensitivity and precise pressure control compared to standard neoprene diaphragms. This material choice also minimizes the risk of off-gassing, preserving the purity of the gas stream. The regulator features a two-stage design, which is critical for applications requiring constant delivery pressure. As the cylinder pressure drops, a single-stage regulator would typically show a rise in outlet pressure (the decaying inlet characteristic). The two-stage mechanism of the Silverline series eliminates this fluctuation, maintaining a steady output from a full cylinder down to depletion.

Durability and cleanliness are paramount in the Silverline series. The body, bonnet, and gauges are fully plated, offering enhanced protection against environmental corrosion and maintaining a clean appearance suitable for lab settings. A filtered seat is integrated into the design to trap particulates, further ensuring gas stream purity and extending the service life of the regulator seat. Additionally, the unit is capable of withstanding vacuums generated during purging operations, a common procedure in high-purity gas handling to eliminate atmospheric contamination before use.

Safety and ease of use are also key features. The regulator includes a built-in capturable preset safety relief valve to protect downstream equipment from over-pressurization. Large, 2-1/2 inch single-scale gauges make it easy to monitor cylinder and delivery pressures at a glance. With a maximum inlet pressure of 3500 PSI and a CGA 580 connection, this regulator is compatible with standard high-pressure cylinders of inert gases such as Nitrogen, Argon, and Helium.
