220-2000 - Miller Smith 220 Series Silverline High Purity Two-Stage Regulator, 0-15 PSI, 1/4" FNPT

Precision Control for Analytical Instrumentation

The Miller Smith 220-20-00 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 the integrity of your gas stream is maintained from the cylinder to the instrument. The core of its performance lies in the stainless steel diaphragm, which provides a non-contaminating surface and precise response to pressure changes, making it superior to standard rubber or neoprene diaphragms found in general-purpose regulators.

Stability is paramount in analytical applications such as gas chromatography, thermal conductivity, and flame ionization. The 220 Series utilizes a two-stage design that drops the cylinder pressure in two steps. This configuration allows the regulator to deliver a constant outlet pressure of 0-15 PSI regardless of fluctuations in the inlet pressure as the supply cylinder is depleted. This "flat" delivery characteristic eliminates the need for constant manual adjustments and ensures consistent results in sensitive calibration and carrier gas applications.

Durability and purity go hand-in-hand with the Silverline series. The body, bonnet, and gauges are fully plated to resist corrosion and maintain a clean aesthetic suitable for laboratory settings. A filtered seat mechanism traps particulates before they can damage the seating surface, significantly extending the service life of the unit and ensuring gas purity. Additionally, the regulator is designed to withstand vacuums, making it compatible with purge cycles often required in high-purity systems. Safety is addressed with a built-in capturable preset relief valve, protecting downstream equipment from over-pressurization.
