120-2002 - Miller Smith Silverline 120 Series Two-Stage CO2 Regulator 0-30 PSI CGA 320

Precision Control with Miller Smith Silverline Series

The Miller Smith 120-20-02 Silverline Series General Purpose Two Stage Regulator is engineered for professionals who demand consistent and precise gas delivery. As part of the renowned Silverline 120 Series, this regulator is designed to handle inert and non-corrosive gases, specifically configured with a CGA 320 inlet for Carbon Dioxide (CO2) service. Its two-stage architecture is a critical feature for applications requiring unwavering outlet pressure; by reducing pressure in two steps, it eliminates the fluctuation often seen in single-stage regulators as the supply cylinder empties. This makes it an excellent choice for laboratory environments, testing facilities, and general maintenance shops where accuracy is paramount.

Robust Construction and Reliability

Durability is at the core of the 120-20-02's design. The body is machined from rugged brass bar stock, ensuring it can withstand the rigors of daily industrial use. To further enhance its longevity and resistance to environmental factors, the body, bonnet, and gauges feature a high-quality plated finish. Inside, the regulator utilizes Sure-Seat technology, which includes a filtered seat to trap particulates, preventing seat degradation and maintaining gas stream purity. This attention to detail extends the service life of the unit and reduces maintenance downtime.

Optimized for Low-Pressure Applications

With a delivery range of 0-30 PSIG (often referenced as a 15 PSI model for specific set-point applications), this regulator provides exceptional control at lower pressures. The large 1-7/8 inch diaphragm is highly sensitive, allowing for fine adjustments that are crucial when working with delicate equipment or processes. The easy-to-read 2-1/2 inch single scale gauges allow operators to monitor cylinder and delivery pressure at a glance. Whether you are managing CO2 for blanketing, purging, or analytical work, the Miller Smith 120-20-02 delivers the reliability and performance synonymous with the Miller brand.

Safety and Compliance

Safety is built into every component. The regulator includes a preset safety relief valve that vents to the atmosphere, providing a fail-safe against over-pressurization. Note that due to this venting mechanism, this regulator is suitable only for non-hazardous gases like CO2. The unit is tapped for rear panel mounting, offering versatile installation options for fixed systems or benchtop setups.
