223-4109 - Miller Smith Silverline 220 Series High Purity Two-Stage Regulator CGA 580

Precision Control for Analytical Applications

The Miller Smith 223-41-09 Silverline High Purity Analytical Two Stage Regulator is engineered to meet the rigorous demands of laboratory and analytical environments. Designed specifically for high purity, non-corrosive gas applications, this regulator ensures that the integrity of your gas stream is maintained from the cylinder to the instrument. The core of its precision lies in the stainless steel diaphragm, which provides superior sensitivity and control compared to standard elastomeric diaphragms. This material choice not only enhances pressure stability but also eliminates the risk of off-gassing or contamination that can compromise sensitive results in gas chromatography and other analytical techniques.

Stability is paramount when dealing with carrier gases and calibration mixtures. The 220 Series utilizes a true two-stage design, which steps down the cylinder pressure in two distinct phases. This configuration guarantees a constant delivery pressure of 0-150 PSI, regardless of fluctuations in the inlet pressure as the supply cylinder empties. For professionals running long-duration tests or critical calibration sequences, this feature eliminates the need for constant manual adjustments and ensures data consistency.

Durability and cleanliness go hand-in-hand with the Silverline series. The regulator features a rugged brass bar stock construction that is fully plated—including the body, bonnet, and gauges—to offer superior protection against environmental corrosion and to maintain a clean aesthetic suitable for lab environments. A filtered seat mechanism is integrated to trap particulates, further protecting the seat assembly and extending the service life of the unit. Additionally, the regulator is designed to withstand vacuums generated during purging operations, making it a versatile tool for complex gas delivery systems.

Safety and ease of use are also key components of the 223-41-09. It comes equipped with large, easy-to-read 2-1/2 inch single scale gauges and a built-in capturable preset safety relief valve that protects downstream equipment from over-pressurization. With a CGA 580 inlet, it is compatible with standard inert gas cylinders including Nitrogen, Argon, and Helium.
