310-85220000 - Miller Smith 310 Series Silverline High Purity Stainless Steel Regulator, CGA 330, 0-25 PSIG

Precision Control for High Purity and Corrosive Gases

The Miller Smith 310-85-22-00-00 Silverline High Purity Regulator is an advanced single-stage pressure control device engineered specifically for the rigorous demands of specialty gas delivery. Designed to maintain the integrity of high-purity systems, this regulator excels in applications involving corrosive, non-corrosive, or toxic gases. The core of its performance lies in its material construction; all wetted parts are manufactured from 316 PCTFE and 316 Stainless Steel. This selection of materials ensures that the regulator remains inert to aggressive media, preventing corrosion that could compromise system safety or gas purity.

One of the standout technical features of the 310 Series is the convoluted stainless steel diaphragm. Unlike standard flat diaphragms, this convoluted design offers superior sensitivity and response to pressure changes, allowing for highly accurate regulation of delivery pressure within the 0-25 PSIG range. The diaphragm utilizes a metal-to-metal seal against the body, eliminating the need for elastomeric seals that can degrade over time or introduce contaminants. This metal-to-metal integrity is crucial for maintaining a leak-tight system, especially when handling hazardous gases where even minute leaks are unacceptable.

Safety and versatility are integral to the design. The regulator includes a captured vent port (1/16” FNPT) located in the bonnet. 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 the immediate work environment. Additionally, the unit is capable of withstanding an internal vacuum, making it suitable for purge cycles and vacuum applications often required in analytical laboratories. The 316 stainless steel filtered seat further enhances reliability by trapping particulates before they can damage the seating surface, thereby extending the operational lifespan of the unit. With mounting options for both front and rear panels, the Miller Smith 310 Series provides a flexible, high-performance solution for complex gas delivery networks.
