322-00200100 - Miller Smith 320 Silverline Series 2-Stage SS Regulator CGA 320 0-100 PSI

Precision Control for Specialty Gas Applications

The Miller Smith 322-00-20-01-00 High Purity Two-Stage Regulator represents the pinnacle of gas control technology within the 320 Silverline Series. Designed specifically for applications requiring absolute precision and cleanliness, this regulator is engineered to handle both corrosive and non-corrosive gases with ease. The unit is configured with a CGA 320 inlet connection, making it the ideal choice for high-purity Carbon Dioxide (CO2) service in laboratory, analytical, or process environments where contamination is not an option.

At the core of this device is its 316 Stainless Steel bar stock body and a convoluted stainless steel diaphragm. This metal-to-metal diaphragm seal is a critical feature, ensuring maximum leak integrity and preventing the outgassing or contamination often associated with elastomeric seals. The seat is constructed from PCTFE, a material chosen for its chemical resistance and ability to maintain a tight seal under varying conditions, thereby extending the service life of the regulator even in demanding cycles. The two-stage architecture is essential for analytical work; it steps down the pressure in two phases, ensuring that the delivery pressure remains rock-steady at your set point (0-100 PSIG) even as the cylinder pressure drops from a full 3500 PSIG down to empty.

Safety and versatility are built into the design. The bonnet features captured vent ports (1/16" FNPT) on both stages, allowing users to pipe vented gases away to a safe location—a mandatory requirement when handling hazardous or toxic media. Furthermore, the regulator is designed to withstand internal vacuums, making it compatible with rigorous purging operations necessary during cylinder changeovers. Whether used for gas chromatography, EPA protocol standards, or laser gas systems, the Miller Smith 322-00-20-01-00 delivers the reliability and purity required by industry professionals.
