222-0309 - Miller Smith Silverline 220 Series Two-Stage Analytical Regulator CGA 580

Miller Smith Silverline: The Standard for High Purity Regulation

For industrial and laboratory professionals requiring exacting control over inert gases, the Miller Smith 222-03-09 Silverline Regulator stands out as a top-tier solution. This two-stage regulator is built to deliver unwavering performance in applications where standard industrial regulators fall short. Whether you are managing gas supply for advanced welding shielding mixtures or, more commonly, precision analytical instruments, the 222-03-09 provides the stability and purity necessary for critical tasks.

The defining characteristic of this model is its ability to provide a flat delivery pressure curve. The two-stage reduction mechanism steps down the high cylinder pressure in two phases, effectively isolating the output pressure from the fluctuations of the supply cylinder. This means that as your gas cylinder drains from 3500 PSI down to the bottom of the tank, your set delivery pressure (adjustable up to 100 PSI) remains rock steady. This reliability is essential for processes that cannot tolerate the "decay" or rising delivery pressure typical of single-stage units.

Durability meets precision in the physical construction of the Silverline 220 Series. The body is machined from solid brass bar stock and finished with a high-quality plating that resists tarnishing and corrosion. Inside, a stainless steel diaphragm replaces standard rubber or neoprene, providing a non-reactive surface that ensures the gas purity is not compromised by the regulator itself. This metal diaphragm also offers superior sensitivity, allowing for fine-tuned pressure adjustments. The inlet is equipped with a CGA 580 connection, suitable for inert gases like Argon, Helium, and Nitrogen, while the outlet features a 1/4-inch tube fitting for secure integration into laboratory tubing systems.

Miller has also integrated key maintenance and safety features. A filtered seat prevents microscopic debris from damaging the sealing surface, significantly prolonging the regulator's operational life. The automatic reseating safety relief valve adds a layer of protection for both the user and the equipment. With its combination of robust plated construction, high-precision stainless steel internals, and reliable two-stage performance, the Miller Smith 222-03-09 is the professional's choice for high-purity gas regulation.
