320-00240000 - Miller Smith 320 Series High Purity Stainless Steel Two-Stage Regulator, CGA 580, 0-25 PSI

Precision Control for High Purity Applications

The Miller Smith 320-00-24-00-00 is a premium High Purity Corrosion Resistant Stainless Steel Two-Stage Regulator designed for the most demanding industrial and laboratory environments. Part of the renowned 320 Silverline Series, this regulator is engineered to handle both corrosive and non-corrosive gases where maintaining gas stream purity is critical. The unit features a body machined from 316 stainless steel bar stock, ensuring robust resistance to chemical attack and environmental corrosion.

At the heart of this regulator is a sophisticated two-stage mechanism. Unlike single-stage regulators that experience a drop in delivery pressure as the cylinder empties, the 320 Series maintains a constant delivery pressure regardless of inlet pressure fluctuations. This makes it an ideal choice for analytical instruments, chromatography, and other applications requiring unwavering stability. The delivery range of 0-25 PSI allows for fine-tuned low-pressure control, essential for sensitive equipment.

Leak integrity is paramount in high-purity applications. This model utilizes a unique metal-to-metal diaphragm seal and a convoluted stainless steel diaphragm, eliminating the outgassing and permeation issues associated with elastomeric seals. A 316 stainless steel filtered seat further protects the gas stream from particulate contamination while extending the service life of the regulator. For safety, the bonnet includes captured vent ports (1/16" FNPT), allowing hazardous gases to be piped away safely in the unlikely event of a diaphragm failure.

Designed for versatility, the regulator is equipped with a CGA 580 connection suitable for inert gases like Argon, Nitrogen, and Helium. It is rated for a maximum inlet pressure of 3500 PSI and is capable of withstanding internal vacuums during purging operations, making it compatible with rigorous cylinder changeover protocols.
