120-0008 - Miller Smith Silverline 2-Stage Oxygen Regulator 0-15 PSI CGA 540

Precision Control with Miller Smith Silverline Series

The Miller Smith 120-00-08 Silverline Series General Purpose Two Stage Regulator is engineered for applications requiring exacting pressure control and unwavering stability. Designed specifically for Oxygen service with a CGA 540 inlet, this regulator exemplifies the engineering excellence of the Miller Smith brand. The core advantage of this unit lies in its two-stage design. Unlike single-stage regulators that allow delivery pressure to rise as the cylinder pressure decays (a phenomenon known as the supply pressure effect), this two-stage mechanism reduces pressure in two steps. This ensures that the output pressure remains constant at your set point of 0-15 PSIG throughout the entire life of the cylinder, making it an ideal choice for laboratory environments, testing facilities, and precision maintenance operations.

Durability is central to the 120-00-08's construction. The body and bonnet are machined from rugged brass bar stock, offering superior resistance to deformation and corrosion compared to forged or die-cast alternatives. The internal components are equally robust, featuring Miller Smith's proprietary Sure-Seat technology. This filtered seat design prevents microscopic debris from entering the high-pressure seat area, which is the most common cause of regulator failure. By filtering the gas stream, the regulator maintains purity and significantly extends its service life, reducing downtime and replacement costs.

Operational precision is achieved through a large 1-7/8 inch diaphragm, which provides exceptional sensitivity to pressure adjustments. This allows operators to fine-tune the delivery pressure with high accuracy, critical for low-pressure applications in the 0-15 PSIG range. The unit is equipped with large, 2-1/2 inch single-scale gauges that are easy to read at a glance, housed in plated cases for added protection. The body is also tapped for rear panel mounting, offering versatile installation options for fixed systems or benchtop setups. With a maximum inlet pressure rating of 3500 PSIG, this regulator is ready for modern high-pressure cylinders.
