320-00250000 - Miller Smith 320 Series High Purity SS Two-Stage Regulator, CGA 660, 0-25 PSI

Precision Engineering for High Purity Applications

The Miller Smith 320-00-25-00-00 High Purity Corrosion Resistant Stainless Steel Two Stage Regulator is the definitive solution for laboratories and analytical facilities requiring absolute precision and cleanliness in gas delivery. Engineered specifically for high purity and corrosive gas service, this regulator is part of the esteemed 320 Silverline Series, known for its uncompromising quality and performance standards. The unit is constructed from high-grade 316 stainless steel bar stock, ensuring that the wetted path remains inert and resistant to chemical attack, which is critical when handling reactive specialty gases.

At the heart of this regulator is a convoluted stainless steel diaphragm that provides exceptional sensitivity and pressure control. Unlike elastomeric diaphragms that can outgas or degrade over time, the metal-to-metal diaphragm seal ensures maximum leak integrity, boasting a design that prevents contamination of the gas stream. This feature is essential for chromatography, EPA protocol gases, and other applications where even trace impurities can compromise results. The two-stage design further enhances performance by maintaining a constant delivery pressure of 0-25 PSI, regardless of fluctuations in the cylinder's inlet pressure. This means that as your gas supply depletes, your process pressure remains rock-steady, eliminating the need for constant manual adjustments.

Safety and longevity are paramount in the design of the 320 Series. The regulator features a 316 stainless steel filtered seat that not only aids in maintaining gas stream purity but also extends the service life of the component by preventing particulate damage. For applications involving hazardous gases, the bonnet includes a captured vent port (1/16" FNPT), allowing for the safe piping and venting of gases in the unlikely event of a diaphragm failure. Additionally, the regulator is designed to withstand internal vacuums, making it suitable for rigorous purging operations required during cylinder changes. With large, easy-to-read 2-1/2 inch gauges and panel mounting capabilities, this Miller Smith regulator combines functional excellence with user-friendly design.
