123-0010 - Miller Smith Silverline 2-Stage Industrial Air Regulator 250 PSI

Technical Overview of the Miller Smith 123-00-10 Silverline Regulator

The Miller Smith 123-00-10 is a premium component of the Silverline 120 Series, engineered specifically for general purpose applications requiring precise control of inert and non-corrosive gases. This model is configured with a CGA 590 inlet connection, making it the standard choice for Industrial Air cylinders. As a two-stage regulator, it excels in environments where maintaining a constant delivery pressure is critical, regardless of fluctuations in the supply cylinder's pressure. This characteristic makes it superior to single-stage alternatives for laboratory, testing, and precision maintenance applications where pressure stability is paramount.

Constructed from rugged brass bar stock, the body and bonnet are designed to withstand the rigors of industrial environments while minimizing potential leak paths. The unit features a large 1-7/8 inch diaphragm which enhances sensitivity, allowing for fine-tuned pressure adjustments within the 0-250 PSI delivery range. The regulator is rated for a maximum inlet pressure of 3500 PSI, accommodating high-pressure cylinders with ease. A key technical feature is the Sure-Seat technology, which incorporates a filtered seat to prevent particulate contamination from entering the high-pressure seat area, significantly extending the service life of the regulator and ensuring gas stream purity.

The 123-00-10 is equipped with large, 2-1/2 inch single-scale gauges that provide clear readability of both cylinder and delivery pressures. The body is plated for corrosion resistance and includes tapping for rear panel mounting, offering versatility in installation configurations. Safety is addressed via a preset relief valve that vents to the atmosphere, ensuring the device remains within safe operating limits. Note that due to the atmospheric venting and elastomeric components, this regulator is strictly for non-hazardous, non-corrosive gases and is not suitable for applications sensitive to inboard diffusion.
