321-00000102 - Miller Smith 320 Series High Purity Two-Stage Stainless Steel Regulator, 0-50 PSI

Precision Control for Specialty Gases

The Miller Smith 320 Series "Silverline" Two-Stage Regulator (Model 321-00-00-01-02) is the professional's choice for managing specialty, high-purity, and corrosive gases. In industries ranging from petrochemicals to pharmaceutical manufacturing, the integrity of your gas delivery system is paramount. This regulator is engineered to deliver unwavering performance, utilizing a two-stage design that steps down pressure in two increments. This mechanism ensures that your output pressure remains constant at your set point (0-50 PSIG), regardless of how much gas is left in the cylinder. This eliminates the "droop" effect common in single-stage regulators, providing you with consistent flow and protecting sensitive downstream equipment from pressure fluctuations.

Built to last in the toughest environments, the 321-00-00-01-02 is constructed from premium 316 stainless steel. Unlike brass regulators that can corrode and fail when exposed to aggressive gases, this stainless steel unit resists chemical attack, ensuring a long operational life and reducing replacement costs. The internal components are equally robust, featuring a PCTFE seat and a stainless steel diaphragm. The metal-to-metal diaphragm seal is a critical feature for maintaining gas purity, as it prevents atmospheric contamination and eliminates the risk of rubber or plastic components leaching into your gas stream. This makes it an ideal solution for applications where purity is non-negotiable.

Safety is built into every aspect of the Miller Smith design. When working with hazardous or toxic gases, you need equipment that prioritizes operator protection. This regulator includes captured vent ports that allow you to safely pipe away any vented gas in the unlikely event of a diaphragm failure. The large, easy-to-read 2-1/2 inch gauges allow for quick visual confirmation of system status. Additionally, the regulator is backed by Miller's reputation for quality and the True Blue warranty, giving you peace of mind. Whether you are setting up a new lab bench or upgrading an industrial process line, the Miller Smith 320 Series regulator provides the safety, durability, and precision you need to get the job done right.
