311-00320000 - Miller Smith 310 Silverline SS Single Stage Regulator, CGA 590, 0-50 PSIG

Precision Control for High Purity and Corrosive Gases

The Miller Smith 311-00-32-00-00 Silverline High Purity Regulator is an elite-tier pressure control device engineered specifically for the rigorous demands of analytical instrumentation, process control, and specialty gas management. Part of the renowned 310 Silverline Series, this single-stage regulator is constructed almost entirely from 316 Stainless Steel bar stock, ensuring exceptional resistance to corrosion and minimizing particle generation in the gas stream. This specific model is configured with a CGA 590 inlet connection and provides a delivery pressure range of 0-50 PSIG, making it ideal for applications requiring precise low-to-mid pressure regulation of sulfur hexafluoride and other compatible industrial gases.

Technical integrity is the cornerstone of the 310 Series design. The regulator features a convoluted stainless steel diaphragm that offers superior sensitivity and stable pressure regulation compared to flat diaphragm designs. Crucially, the diaphragm utilizes a metal-to-metal seal with the body, eliminating the need for elastomeric seals that can degrade, outgas, or leak over time. This design achieves maximum leak integrity, essential when handling toxic or high-cost high-purity gases. The seat assembly is crafted from PCTFE (Polychlorotrifluoroethylene), a material chosen for its hardness, chemical resistance, and ability to maintain a tight shut-off even in corrosive environments. A built-in filter within the seat assembly further protects the regulator from particulate contamination, extending the service life of the unit.

Safety and versatility are integrated into the housing. The bonnet includes a captured 1/16-inch FNPT vent port, allowing operators to pipe hazardous fumes away to a safe exhaust system in the event of a diaphragm failure. The unit is also capable of withstanding an internal vacuum, facilitating effective purging cycles during cylinder changeovers to maintain system purity. With a maximum inlet pressure rating of 3500 PSIG and large, easy-to-read 2-1/2 inch single scale gauges, the Miller Smith 311-00-32-00-00 provides the reliability and performance required for critical laboratory and industrial gas systems.
