OVERVIEW

Precision Control for Specialty Gases


The Miller Smith 620-81-09-00-00 Silverline High Purity Brass Two Stage Regulator is engineered for the rigorous demands of analytical laboratories and high-precision industrial applications. Designed specifically for non-corrosive specialty gases, this regulator exemplifies the Miller Smith commitment to quality and accuracy. The 620 Series Silverline distinguishes itself with a robust two-stage design, ensuring that delivery pressure remains constant even as the inlet pressure from the cylinder fluctuates. This feature is critical for applications requiring unwavering flow stability over the life of the gas cylinder.



At the heart of this regulator is a unique, specially designed stainless steel diaphragm. Unlike elastomeric diaphragms that can degrade or off-gas, the stainless steel construction offers superior chemical resistance and maintains the purity of the gas stream. The metal-to-metal seal between the body and the diaphragm eliminates the need for gaskets that could introduce contaminants, further ensuring the integrity of your process gas. A 316 stainless steel filter is integrated into the inlet to trap particulates, protecting the seat and extending the service life of the unit.



Safety and versatility are paramount in the 620 Series design. The regulator features a nickel-plated brass bar stock body that provides excellent durability and corrosion resistance for the intended service environment. It is equipped with capturable vents in the bonnet (1/16" FNPT) for both stages, allowing for the safe piping away of hazardous gases in the unlikely event of a diaphragm failure. Additionally, the unit is capable of withstanding internal vacuums, making it suitable for purging operations without risk of damage. With a delivery range of 30" Hg vacuum to 30 PSI and a maximum inlet pressure of 3500 PSI, this regulator is a versatile tool for precise gas management.
