122-0002 - Miller Smith Silverline 2-Stage CO2 Regulator, CGA 320, 0-100 PSI Delivery

Precision Control with Miller Smith Silverline Series

The Miller Smith 122-00-02 Silverline Series General Purpose Two-Stage Regulator is engineered for professionals who demand consistent performance and reliability in their gas control systems. Specifically configured for Carbon Dioxide (CO2) applications, this regulator features a CGA 320 inlet connection, making it the ideal choice for laboratories, industrial plants, and maintenance shops where pure gas delivery is critical. As part of the renowned Silverline 120 Series, this unit distinguishes itself with a robust two-stage design. Unlike single-stage regulators that experience delivery pressure fluctuations as the cylinder drains, this two-stage mechanism maintains a steady 100 PSI output (adjustable range 0-100 PSIG) from full cylinder pressure down to depletion, ensuring your processes remain stable and accurate without constant manual adjustment.

Durability is at the core of the 122-00-02's construction. The body and bonnet are machined from rugged brass bar stock, providing superior strength compared to forged or die-cast alternatives. This solid construction is complemented by a plated finish that resists corrosion and wear in harsh industrial environments. Internally, the regulator utilizes Miller Smith's advanced Sure-Seat technology. This filtered seat design prevents debris and particulate matter from entering the high-pressure seat area, significantly extending the service life of the regulator and maintaining gas stream purity. The large 1-7/8 inch diaphragm offers exceptional sensitivity, allowing for precise pressure control across the entire delivery range.

User convenience and safety are also paramount. The regulator is equipped with large, easy-to-read 2-1/2 inch single-scale gauges that provide clear readings of both cylinder and delivery pressure. The outlet is configured with a 1/4" FNPT connection, offering versatility for various hose and fitting adaptations. A preset safety relief valve vents to the atmosphere, adding a layer of protection for non-hazardous gas applications. Whether you are managing CO2 for shielding gas, pneumatic tools, or analytical instruments, the Miller Smith 122-00-02 delivers the unwavering precision and longevity required for high-stakes industrial environments.
