313-00200000 - Miller Smith Silverline 310 Series SS Regulator, 0-250 PSIG, CGA 320

Precision Control for High Purity Applications

The Miller Smith 313-00-20-00-00 Silverline High Purity Regulator is an elite component designed for the most demanding gas delivery systems. Engineered specifically for applications involving corrosive, non-corrosive, or toxic gases, this single-stage regulator ensures the integrity of your gas stream is never compromised. The unit is built around a 316 stainless steel bar stock body, providing exceptional resistance to chemical attack and environmental corrosion, making it a staple in laboratory, research, and industrial specialty gas environments.

Advanced Material Construction

At the heart of the 310 Silverline series is a commitment to material purity. All wetted parts—those exposed to the flowing media—are constructed from 316 PCTFE or 316 Stainless Steel. This includes a specialized 316 stainless steel filtered seat which not only adds to the gas stream purity but significantly extends the service life of the regulator by preventing particulate damage. The diaphragm is also crafted from stainless steel and features a convoluted design. This engineering choice allows for maximum accuracy and stable regulation of delivery pressure, minimizing the hysteresis often found in flat diaphragm designs.

Safety and Leak Integrity

Safety is paramount when handling hazardous or toxic gases. The Miller Smith 313-00-20-00-00 addresses this with a metal-to-metal diaphragm seal that provides maximum leak integrity, ensuring that hazardous gases remain contained within the system. Furthermore, the bonnet is equipped with a captured vent port (1/16" FNPT). In the unlikely event of a diaphragm failure, this port allows for the safe piping and venting of hazardous gases away from the operator and workspace. This feature is critical for compliance with safety protocols in high-purity gas handling.

Versatile Installation and Monitoring

Designed for integration into complex systems, the regulator features a bonnet threaded for front panel mounting and a body tapped for rear panel mounting, offering flexibility in system design. The large 2-1/2 inch single scale gauges provide clear, easy-to-read pressure data at a glance. With a delivery range of 0-250 PSIG and a maximum inlet pressure of 3500 PSIG, this regulator is a robust solution for precise gas control. Note that a Cross Purge Assembly is recommended for use with this series to ensure effective purging of hazardous gas traces during cylinder changes.
