123-2002 - Miller Smith Silverline 2-Stage CO2 Regulator 250 PSI CGA 320

Precision CO2 Control with Miller Smith Silverline

The Miller Smith 123-20-02 Silverline Series General Purpose Two Stage Regulator is engineered for professionals requiring consistent and precise control of Carbon Dioxide (CO2). As part of the renowned Silverline 120 Series, this regulator features a robust two-stage design. Unlike single-stage counterparts, the two-stage mechanism reduces cylinder pressure in two steps, ensuring that the delivery pressure remains constant even as the cylinder pressure drops during use. This characteristic makes it an excellent choice for laboratory settings, general plant maintenance, and applications where pressure stability is critical.

Constructed from rugged brass bar stock, the body is built to withstand the rigors of industrial environments. The exterior, including the bonnet and gauges, is plated for superior protection against corrosion and wear. Inside, Miller's proprietary Sure-Seat technology incorporates a filtered seat that prevents debris from entering the high-pressure seating area, significantly extending the service life of the regulator and maintaining gas purity. The large 1-7/8 inch diaphragm allows for sensitive pressure adjustments, while the 2-1/2 inch single-scale gauges provide clear, easy-to-read metrics.

Equipped with a CGA 320 inlet connection, this model is specifically configured for CO2 cylinders. It offers a delivery pressure range of up to 250 PSIG and can handle a maximum inlet pressure of 3500 PSIG. A preset safety relief valve is included to vent excess pressure to the atmosphere, adding a layer of safety for non-hazardous gas applications. Whether for pneumatic testing, blanketing, or process control, the 123-20-02 delivers reliability and performance.
