122-2002 - Miller Smith Silverline 2-Stage CO2 Regulator, 0-100 PSI, CGA 320

Precision Two-Stage CO2 Control

The Miller Smith 122-20-02 Silverline Series Regulator is a high-performance general-purpose regulator engineered for applications requiring absolute pressure stability. As a two-stage regulator, it reduces cylinder pressure in two distinct steps, ensuring that the delivery pressure remains constant even as the cylinder pressure drops during use. This feature is critical for laboratory, analytical, and precision maintenance applications where fluctuations in gas flow can compromise results.

Robust Construction & Reliability

Built to withstand the rigors of industrial environments, this regulator features a body machined from solid brass bar stock, which is then plated for enhanced corrosion resistance and durability. The internal mechanism includes a large 1-7/8 inch diaphragm that provides exceptional sensitivity and precise control over the 0-100 PSIG delivery range. Additionally, the regulator is equipped with Miller's Sure-Seat technology, which incorporates a filtered seat to trap particulates and prevent debris from damaging the seating surface, significantly extending the service life of the unit.

Optimized for Carbon Dioxide

This specific model comes configured with a CGA 320 inlet connection, making it directly compatible with standard Carbon Dioxide (CO2) cylinders. It also features a 1/4" MNPT needle valve outlet for fine flow adjustments. The large 2-1/2 inch single-scale gauges are easy to read, allowing operators to monitor cylinder and delivery pressure at a glance. With a maximum inlet pressure rating of 3500 PSIG, the 122-20-02 is a safe and reliable choice for managing high-pressure gas sources in non-hazardous environments.
