122-0005 - Miller Smith Silverline 2-Stage Air Regulator CGA 346 0-100 PSI

Precision Two-Stage Control for Compressed Air

The Miller Smith 122-00-05 Silverline Series General Purpose Two Stage Regulator is engineered for applications requiring consistent delivery pressure and robust durability. Designed specifically for compressed air service, this regulator features a CGA 346 inlet connection and provides a delivery pressure range of 0-100 PSIG. As a two-stage device, it reduces cylinder pressure in two steps, ensuring that the working pressure remains stable even as the cylinder pressure drops during use. This characteristic makes it an excellent choice for laboratories, testing facilities, and precision maintenance shops where pressure fluctuation cannot be tolerated.

Rugged Construction and Reliability

Built to withstand the rigors of industrial environments, the 122-00-05 features a body and bonnet machined from solid brass bar stock. This construction offers superior strength compared to forged or die-cast alternatives. The internal components are equally robust, utilizing Miller's proprietary Sure-Seat technology. This filtered seat design prevents debris and particulate matter from entering the high-pressure seat area, a common cause of regulator failure. By filtering the gas stream, the regulator maintains purity and extends its operational lifespan, reducing maintenance downtime.

Operational Features

The regulator is equipped with a large 1-7/8 inch diaphragm, which provides high sensitivity and precise control over the outlet pressure. Operators can easily monitor system status via the large 2-1/2 inch single-scale gauges, which are plated for corrosion resistance. The unit is rated for a maximum inlet pressure of 3500 PSIG, making it compatible with standard high-pressure air cylinders. Additionally, the body includes tapping for rear panel mounting, allowing for integration into gas management panels or fixed installations. Note that while the Silverline series covers various inert gases, this specific SKU is configured with a CGA 346 fitting for air service.
