221-2009 - Miller Smith 220 Series Silverline High Purity Two-Stage Regulator, CGA 580

Rugged Reliability for Specialty Gas Delivery

The Miller Smith 221-20-09 Silverline Regulator represents the pinnacle of gas control technology for specialty gas delivery. While it is built with the precision required for analytical laboratories, its rugged construction makes it equally suitable for demanding industrial environments where high purity is a requirement. The regulator features a robust brass bar stock construction, which is then plated to resist corrosion and environmental damage. This ensures that the device can withstand the rigors of daily use while maintaining the high standards of cleanliness expected in a Silverline product.

One of the standout features of this model is its two-stage regulation mechanism. In many welding and industrial processes, as a gas cylinder empties, the outlet pressure can fluctuate, leading to inconsistent flow rates. The two-stage design of the 221-20-09 eliminates this issue by stepping down the pressure in two stages, guaranteeing a constant delivery pressure from a full cylinder down to a nearly empty one. This is particularly beneficial for processes requiring a steady 0-50 PSI flow, ensuring process stability and reducing waste. The unit connects via a standard CGA 580 inlet, making it compatible with a wide range of inert gases such as Argon, Helium, and Nitrogen.

Operational efficiency is enhanced by the regulator's thoughtful engineering. It is designed to withstand vacuums generated during purging operations, a common procedure when switching gases or ensuring system cleanliness. The stainless steel diaphragm offers precise control and superior response characteristics compared to rubber alternatives. Furthermore, the automatic reseating safety relief valve adds a layer of protection for both the equipment and the operator. With a maximum inlet pressure rating of 3500 PSI, the Miller Smith 221-20-09 is a versatile and dependable choice for any facility handling high-purity non-corrosive gases.
