121-2002 - Miller Smith Silverline 2-Stage CO2 Regulator 0-60 PSI CGA 320

Precision CO2 Control for Laboratory and Industrial Applications

The Miller Smith 121-20-02 Silverline Series General Purpose Two Stage Regulator is engineered to meet the rigorous demands of laboratory and analytical environments where gas purity and pressure stability are paramount. Designed specifically for Carbon Dioxide (CO2) service with a CGA 320 inlet connection, this regulator exemplifies the quality and reliability associated with the Miller Smith brand. The two-stage design is a critical feature for applications requiring unwavering consistency; unlike single-stage regulators that may allow delivery pressure to fluctuate as the supply cylinder drains, this unit maintains a constant output pressure throughout the life of the cylinder.

At the heart of the 121-20-02 is a large 1-7/8 inch diaphragm, which provides exceptional sensitivity and precise control over the delivery pressure range of 0-60 PSIG. This level of control is essential for sensitive instrumentation and process control where even minor deviations can impact results. The regulator also features Miller's proprietary Sure-Seat technology and a filtered seat design. These features work in tandem to prevent debris from entering the seating area, thereby ensuring maximum gas stream purity and significantly extending the service life of the regulator. This makes it an ideal choice for facilities that cannot afford downtime due to equipment failure or contamination.

Durability is not sacrificed for precision. The body is machined from rugged brass bar stock and finished with a high-quality plating that protects the bonnet, body, and gauges from corrosion and wear. The large 2-1/2 inch single scale gauges are easy to read, allowing operators to monitor cylinder and delivery pressure at a glance. Whether used for inert gas blanketing, analytical instruments, or general plant maintenance, the Miller Smith 121-20-02 delivers the performance and reliability required by professional gas users.
