320-83250000 - Miller Smith 320 Series High Purity Stainless Steel Two-Stage Regulator, 0-25 PSI, CGA 660

Precision and Purity for Specialty Gas Applications

When your operation demands absolute precision and uncompromised purity, the Miller Smith 320 Series High Purity Stainless Steel Regulator is the professional's choice. Designed for welders, lab technicians, and industrial operators handling corrosive or specialty gases, this regulator eliminates the variables that can ruin a process. Whether you are managing calibration gases, laser mixtures, or corrosive chemical feeds, the 320-83-25-00-00 ensures that the gas delivered to your equipment is as pure as the gas in the cylinder.

The two-stage design is a game-changer for consistency. In single-stage regulators, delivery pressure can fluctuate as the cylinder pressure drops—a phenomenon known as the "decaying inlet characteristic." This Miller Smith regulator solves that problem by stepping down the pressure in two stages, providing a rock-steady 0-25 PSIG output regardless of whether your tank is full (3500 PSIG) or nearing empty. This stability is essential for long-duration processes where constant monitoring isn't feasible.

Durability is built into every component. The body and internal wetted parts are machined from 316 stainless steel, offering superior resistance to corrosion compared to standard brass regulators. This makes it compatible with a wide range of aggressive gases that would otherwise eat through lesser equipment. The regulator also features a metal-to-metal diaphragm seal, removing rubber or plastic seals that could leak or contaminate your gas stream. For added safety, the captured vent ports allow you to pipe hazardous fumes away from the workspace, ensuring a safer environment for your team. With easy-to-read 2-1/2 inch gauges and a standard CGA 660 connection, this regulator is ready to integrate seamlessly into your high-purity gas system.
