622-03100000 - Miller Smith Silverline 620 Series High Purity 2-Stage Regulator CGA 590

Precision Control for Specialty Gases

The Miller Smith 622-03-10-00-00 Silverline High Purity Brass Two Stage Regulator is an elite solution designed for the rigorous demands of non-corrosive specialty gas applications. Engineered within the renowned 620 Silverline Series, this regulator exemplifies precision and reliability. It is specifically configured with a CGA 590 connection, making it suitable for Industrial Air and Sulfur Hexafluoride applications where maintaining gas stream integrity is paramount. The unit features a robust nickel-plated brass bar stock body which not only provides a professional aesthetic but also offers enhanced durability and resistance to environmental factors compared to standard brass models.

At the core of this regulator's performance is its two-stage reduction mechanism. Unlike single-stage counterparts, this design compensates for the drop in cylinder pressure as the gas is consumed, delivering a steady, unwavering outlet pressure of 0-100 PSI throughout the life of the cylinder. This characteristic is critical for analytical instrumentation where pressure drift can compromise data validity. The regulator utilizes a specially designed stainless steel diaphragm, which provides a metal-to-metal seal with the body. This construction eliminates the off-gassing associated with elastomeric diaphragms, ensuring that the high purity of the source gas is maintained all the way to the process application.

Safety and versatility are also key components of the 622-03-10-00-00. The bonnet includes a captured 1/16" FNPT vent port, allowing for the safe piping of vented gases away from the work area in the unlikely event of a diaphragm failure. Additionally, the regulator is designed to withstand internal vacuums, facilitating effective purging operations without damage to the internal components. A 316 stainless steel filter protects the seat from particulate damage, extending the service life of the unit. With threaded front and rear bonnets, this regulator is also ready for panel mounting, offering flexibility for laboratory and industrial system integrations.
