122-4010 - Miller Smith Silverline 2-Stage Industrial Air Regulator 0-100 PSI CGA 590

Precision Control for Industrial Air Applications

The Miller Smith 122-40-10 Silverline Series General Purpose Two Stage Regulator is engineered for professionals who demand reliability and precision in gas control. Designed specifically for Industrial Air applications utilizing a CGA 590 inlet connection, this regulator exemplifies the high manufacturing standards of the Miller Smith brand. As part of the renowned Silverline 120 Series, it combines rugged durability with sensitive pressure management, making it a top choice for laboratory, plant, and maintenance shop environments.

Two-Stage Performance

Unlike single-stage counterparts, this two-stage regulator reduces cylinder pressure in two distinct steps. This mechanical advantage ensures that the delivery pressure remains constant even as the pressure in the supply cylinder drops. For applications where consistent flow is critical—such as calibration, testing, or continuous process supply—the 122-40-10 eliminates the need for frequent manual adjustments, providing a stable 0-100 PSI delivery range throughout the life of the cylinder.

Advanced Construction and Purity

Constructed from solid brass bar stock, the body of the regulator is built to withstand the rigors of daily industrial use. The exterior features a plated finish on the body, bonnet, and gauges, offering superior protection against corrosion and wear. Internally, Miller Smith's Sure-Seat technology incorporates a filtered seat that prevents debris from entering the high-pressure seating area. This feature significantly extends the service life of the regulator and maintains gas stream purity, which is essential for sensitive instrumentation.

User-Friendly Features

The unit is equipped with a large 1-7/8 inch diaphragm, which allows for highly responsive pressure control. Operators can easily monitor system status via the large 2-1/2 inch single scale gauges, which provide clear readings of both cylinder and delivery pressure. The inclusion of a 1/4" FNPT needle valve on the outlet offers added versatility, allowing for fine-tuning of gas flow directly at the regulator. With a maximum inlet pressure rating of 3500 PSI, this regulator is ready for high-pressure industrial cylinders.
