123-0002 - Miller Smith Silverline 2-Stage CO2 Regulator 0-250 PSI

Precision Control with Miller Smith Silverline Series

The Miller Smith 123-00-02 Silverline Series General Purpose Two Stage Regulator is engineered for applications requiring unwavering delivery pressure and exceptional durability. Designed for use with Carbon Dioxide (CO2) via a CGA 320 inlet connection, this regulator is a staple in laboratories, general plant facilities, and maintenance shops where gas purity and flow consistency are paramount. The unit features a robust brass bar stock body, ensuring it can withstand the rigors of industrial environments while maintaining the precision required for analytical work.

Two-Stage Performance

Unlike single-stage counterparts, this two-stage regulator reduces cylinder pressure in two steps. This mechanical advantage ensures that the delivery pressure remains constant throughout the life of the cylinder, even as the inlet pressure decays. This feature is critical for processes that cannot tolerate pressure fluctuations, such as calibration testing, blanketing, or precise pneumatic control. The large 1-7/8 inch diaphragm further enhances sensitivity, allowing operators to dial in exact pressure settings within the 0-250 PSI delivery range.

Advanced Engineering and Safety

Miller Smith has integrated their proprietary Sure-Seat technology into the 123-00-02. This filtered seat design prevents particulate contamination from entering the high-pressure seat area, a common cause of regulator failure. By filtering the gas stream, the regulator achieves added purity and an extended service life. Safety is addressed with a preset relief valve that vents to the atmosphere, making this unit suitable for non-hazardous, non-corrosive gases. The body, bonnet, and 2-1/2 inch gauges are plated for superior protection against environmental corrosion. Additionally, the body is tapped for rear panel mounting, offering versatile installation options for fixed systems.
