310-66000000 - Miller Smith 310 Series Silverline Stainless Steel High Purity Regulator, 0-25 PSIG

Precision Control for High Purity Applications

The Miller Smith 310-66-00-00-00 Silverline High Purity Regulator is an elite solution designed for the rigorous demands of laboratory, analytical, and specialty gas applications. Engineered to maintain the integrity of high-purity systems, this single-stage regulator is constructed almost entirely from 316 stainless steel bar stock. This material choice is critical for preventing contamination and ensuring compatibility with corrosive, non-corrosive, and toxic gases. The regulator features a 316 PCTFE (Polychlorotrifluoroethylene) filtered seat, which not only aids in maintaining gas stream purity but also significantly extends the service life of the unit by resisting chemical degradation.

At the heart of the 310 Series is a specially designed, convoluted stainless steel diaphragm. Unlike standard rubber or neoprene diaphragms, this metal diaphragm provides a metal-to-metal seal, ensuring maximum leak integrity—a non-negotiable feature when handling hazardous media. The convoluted design allows for extremely precise control of delivery pressure, offering stable regulation even as cylinder pressure decays. This specific model provides a delivery pressure range of 0-25 PSIG, making it ideal for low-pressure applications requiring fine adjustments. Furthermore, the regulator is capable of withstanding an internal vacuum, which is essential for effective purging cycles during cylinder changes.

Safety is paramount in the design of the Silverline series. The bonnet includes a captured vent port (1/16" FNPT), which allows operators to pipe vented gases away to a safe location in the rare event of a diaphragm failure. This feature is particularly important when working with toxic or flammable gases. The unit is also designed for versatility in installation, featuring a threaded bonnet for front panel mounting and a tapped body for rear panel mounting. Large, 2-1/2 inch single-scale gauges provide clear, immediate visual feedback on system status. Whether used in gas chromatography, emission monitoring systems, or research laboratories, the Miller Smith 310 Series delivers the reliability and purity required for critical processes.
