622-00050000 - Miller Smith Silverline 620 Series High Purity Air Regulator, 2-Stage, 0-100 PSI

Precision Control for High Purity Applications

The Miller Smith 622-00-05-00-00 Silverline High Purity Brass Two-Stage Regulator is engineered for professionals who demand exacting standards in gas delivery. Designed specifically for non-corrosive gases like compressed air (CGA 346), this regulator is part of the renowned 620 Silverline Series. It is built to provide constant, unwavering outlet pressure regardless of fluctuations in inlet pressure, making it an ideal choice for laboratory environments, gas chromatography, and analytical instrumentation where stability is paramount.

At the core of this regulator is a specially designed stainless steel diaphragm. Unlike elastomeric diaphragms that can absorb or release contaminants, the stainless steel construction ensures maximum accuracy and maintains the purity of the gas stream. This is further reinforced by a metal-to-metal body-to-diaphragm seal, which eliminates the need for gaskets that could outgas or degrade over time. The body itself is machined from nickel-plated brass bar stock, offering excellent durability and diffusion resistance, ensuring that the gas you deliver is as pure as the gas in the cylinder.

Safety and versatility are also key features of the 622-00-05-00-00. It includes a capturable vent in the bonnet (1/16" FNPT), allowing for the safe venting of gases if necessary. The unit is equipped with a 316 stainless steel filter to protect the seat from particulate damage, extending the service life of the regulator. With a delivery range of 0-100 PSIG and a maximum inlet pressure of 3500 PSIG, this regulator handles high-pressure cylinders with ease. The threaded front and rear bonnet design also facilitates panel mounting, providing flexibility for system integration.
