222-2002 - Miller Smith Silverline 220 Series High Purity Two-Stage Regulator CGA 320

Reliable High Purity Gas Control

When your work demands the highest level of accuracy and cleanliness, the Miller Smith 222-20-02 Silverline Regulator delivers. While Miller is famous for industrial toughness, their Silverline series brings that same durability to the laboratory bench. This high-purity, two-stage regulator is built for applications where standard industrial regulators simply cannot perform, such as gas chromatography and precision calibration. If you are working with Carbon Dioxide (CO2) in a critical setting, this regulator with a CGA 320 connection is the professional choice.

Built for Consistency

Fluctuating gas pressure can ruin a calibration or a test run. The Miller Smith 222-20-02 solves this with its two-stage regulation mechanism. By stepping down the pressure twice, it ensures that your output pressure remains rock-steady at your set point (0-100 PSI), regardless of how much pressure is left in the tank. This means you can use your gas cylinders more completely without worrying about the "end-of-tank" pressure spike common in cheaper regulators.

Rugged and Readable

Durability doesn't take a backseat to precision here. The regulator features a rugged brass bar stock construction that is fully plated for corrosion resistance and easy cleaning. The large, 2-1/2 inch single scale gauges are easy to read at a glance, allowing operators to monitor tank and delivery pressure without squinting. The unit also features a stainless steel diaphragm, which is critical for preventing internal contamination and ensuring precise response to pressure adjustments.

Safety and Longevity

Invest in equipment that lasts. The 222-20-02 includes a filtered seat design that traps microscopic particles before they can damage the internal sealing surfaces, significantly extending the life of the regulator. For safety, an automatic reseating relief valve is built-in to prevent over-pressurization. Whether you are setting up a new lab station or upgrading your gas delivery system, the Miller Smith Silverline series offers the perfect blend of high-purity performance and industrial-grade reliability.
