310-00200000 - Miller Smith 310 Series Silverline SS Regulator CGA 320 0-25 PSIG

Precision Engineering for High Purity Applications

The Miller Smith 310-00-20-00-00 Silverline High Purity Regulator is a premier solution designed for the rigorous demands of specialty gas delivery. Engineered to maintain the integrity of high purity systems, this single-stage regulator is constructed 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 filtered seat, which not only extends the service life of the unit but also provides added assurance against gas stream impurities.

Advanced Diaphragm Technology

At the heart of the 310 Series is a specially designed convoluted stainless steel diaphragm. This component is engineered to deliver maximum accuracy and stable regulation of delivery pressure, even under fluctuating conditions. The metal-to-metal diaphragm seal is a standout feature, providing superior leak integrity compared to elastomeric seals. This design eliminates the risk of off-gassing and permeation, making it ideal for analytical and process applications where gas purity is paramount. The regulator is also capable of withstanding an internal vacuum, adding to its versatility in various system configurations.

Safety and Operational Features

Safety is a top priority in the design of the Miller Smith 310 Series. The bonnet includes 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 feature is essential for protecting personnel and the environment in laboratory and industrial settings. Additionally, the regulator is equipped with large, 2-1/2 inch single-scale gauges that are easy to read, ensuring operators can monitor system pressure with confidence. The bonnet is threaded for front panel mounting, and the body is tapped for rear panel mounting, offering flexible installation options to suit your specific equipment layout.

Technical Specifications

This specific model comes with a CGA 320 stainless steel inlet connection and provides a delivery pressure range of 0-25 PSIG. It is rated for a maximum inlet pressure of 3500 PSIG. For applications involving corrosive media, all wetted parts are constructed from 316 PCTFE and stainless steel, ensuring long-term durability and resistance to chemical attack. Note that a Cross Purge Assembly is recommended for use with this series to ensure effective purging of hazardous gas traces during cylinder changes.
