622-01090000 - Miller Smith 620 Silverline High Purity 2-Stage Regulator, CGA 580, 0-100 PSI

Precision Control for High Purity Applications

The Miller Smith 622-01-09-00-00 Silverline High Purity Brass Two Stage Regulator is engineered for professionals who demand exacting standards in gas delivery. Part of the renowned 620 Silverline Series, this regulator is specifically designed for non-corrosive specialty gases where maintaining gas stream purity is paramount. The unit features a robust nickel-plated brass bar stock body that resists corrosion and wear, ensuring a long service life even in demanding industrial or laboratory environments.

At the heart of this regulator is a unique stainless steel diaphragm. Unlike standard rubber or elastomer diaphragms, the stainless steel construction prevents off-gassing and contamination, making it ideal for high-purity applications. The metal-to-metal seal between the body and the diaphragm further guarantees a leak-tight enclosure, eliminating the risk of external atmospheric contamination. With a delivery range of 0-100 PSI and a maximum inlet pressure of 3500 PSI, it provides versatile performance for a variety of inert gas setups utilizing a CGA 580 connection.

Stability is the hallmark of the two-stage design. By reducing pressure in two steps, the 622-01-09-00-00 maintains a constant outlet pressure regardless of fluctuations in the supply cylinder. This ensures that your downstream equipment receives a steady, reliable flow of gas from the start of the cylinder to the very end. Additional features include a 316 stainless steel filter to protect the seat, a 2-1/2 inch single scale gauge for clear visibility, and threaded bonnets for easy panel mounting.

Safety is also a key consideration. The regulator includes a capturable vent in the bonnet (1/16" FNPT), allowing users to pipe away gases in the unlikely event of a diaphragm failure—a critical feature for enclosed workspaces. Whether for analytical instrumentation, laser systems, or precision welding, the Miller Smith 622-01-09-00-00 delivers the purity and consistency required for critical operations.
