323-70250000 - Miller Smith 320 Series High Purity 2-Stage Stainless Steel Regulator, CGA 660, 0-250 PSI

High Purity Stainless Steel Regulation

The Miller Smith 323-70-25-00-00 is a premium high-purity, two-stage regulator designed specifically for applications requiring the utmost precision and cleanliness. Part of the 320 Silverline Series, this regulator is engineered to handle both corrosive and non-corrosive gases, making it an essential component for laboratory, research, and industrial specialty gas delivery systems. The unit features a robust 316 stainless steel bar stock body and a convoluted stainless steel diaphragm, ensuring compatibility with aggressive media while maintaining structural integrity over a long service life.

One of the standout features of this model is its metal-to-metal diaphragm seal, which provides maximum leak integrity—a critical factor when working with hazardous or high-purity gases. The regulator utilizes a 316 stainless steel filtered seat that not only aids in maintaining gas stream purity but also protects the internal components from particulate damage. With a delivery pressure range of 0-250 PSI and a maximum inlet pressure of 3500 PSI, it offers versatile performance for various setups. The two-stage design is particularly beneficial for maintaining constant delivery pressure regardless of fluctuations in the cylinder's inlet pressure, ensuring stable flow throughout the life of the cylinder.

Safety is paramount in the design of the 323-70-25-00-00. It includes captured vent ports (1/16" FNPT) in the bonnet, allowing users to pipe hazardous gases away safely in the unlikely event of a diaphragm failure. Additionally, the regulator is designed to withstand internal vacuums, facilitating effective purging operations during cylinder changes. Equipped with a CGA 660 stainless steel connection, this regulator is ready for immediate integration into your high-purity gas system.
