213-0302 - Miller Smith 210 Silverline High Purity CO2 Regulator, 0-150 PSIG, CGA 320

Miller Smith 213-03-02 Silverline High Purity Analytical Regulator

The Miller Smith 213-03-02 is a premium single-stage regulator from the 210 Silverline Series, specifically engineered for high-purity, non-corrosive gas applications. Designed to meet the rigorous demands of instrument analysis, automotive emissions testing, and biological laboratories, this regulator ensures that the integrity of the gas stream is maintained from the cylinder to the application point. The unit features a CGA 320 inlet connection, making it suitable for Carbon Dioxide (CO2) service, and provides a delivery pressure range of 0-150 PSIG.

Central to the performance of the 213-03-02 is its stainless steel diaphragm. Unlike standard neoprene diaphragms, the stainless steel construction prevents off-gassing and absorption, ensuring precise pressure control without contaminating the gas stream. This material choice also provides high resistance to inboard diffusion of atmospheric contaminants, a critical factor in analytical environments. The regulator is constructed from rugged brass bar stock, which is then plated—along with the bonnet and gauges—to offer superior protection against corrosion and wear in laboratory or industrial settings.

Operational safety and longevity are enhanced by a filtered seat mechanism that traps particulates, extending the service life of the regulator components. The unit includes a built-in capturable preset safety relief valve to protect against over-pressurization. For ease of monitoring, the regulator is equipped with large, 2-1/2 inch single-scale gauges that are easy to read at a glance. The body is also tapped for rear panel mounting, providing versatility for installation in gas cabinets or benchtop setups. This regulator is capable of withstanding vacuums generated during purging operations, further solidifying its suitability for high-purity gas management systems.
