310-00310000 - Miller Smith 310 Series Stainless Steel Regulator, CGA 705, 0-25 PSIG

High Purity Precision for Corrosive Environments

The Miller Smith 310-00-31-00-00 Silverline High Purity Regulator is a premium single-stage pressure control device engineered specifically for the rigorous demands of specialty gas delivery. Designed to handle corrosive, non-corrosive, and toxic gases, this regulator is built from high-grade 316 stainless steel bar stock. This construction ensures that all wetted parts resist corrosion and maintain the integrity of the gas stream, making it an essential component for laboratories, semiconductor manufacturing, and industrial chemical processes where purity is paramount.

Advanced Design Features

At the heart of the 310 Series is a specially designed convoluted stainless steel diaphragm. Unlike standard flat diaphragms, this convoluted design provides superior sensitivity and stable regulation of delivery pressure, even as cylinder pressure decays. The diaphragm utilizes a metal-to-metal seal, eliminating the need for elastomeric seals that can degrade or outgas, thereby ensuring maximum leak integrity. A 316 PCTFE filtered seat is incorporated to further protect the regulator from particulate contamination, extending the service life of the unit and ensuring consistent performance.

Safety and Versatility

Safety is a critical focus in the design of the Silverline series. The bonnet features a captured vent port (1/16" FNPT), which allows for the safe piping and venting of hazardous gases in the unlikely event of a diaphragm failure. This model is equipped with a CGA 705 connection, typically used for ammonia and other specific corrosive gases, and delivers a precise pressure range of 0-25 PSIG. The large, 2-1/2 inch single-scale gauges provide clear readability, ensuring operators can monitor system status at a glance. Whether for analytical instrumentation or process control, the Miller Smith 310 Series delivers the purity and precision required for critical applications.
