620-00070000 - Miller Smith 620 Silverline High Purity Regulator, CGA 510, Two-Stage

Precision Control for Specialty Gas Applications

The Miller Smith 620-00-07-00-00 Silverline High Purity Brass Two Stage Regulator is engineered for professionals who demand exacting standards in gas delivery. Designed specifically for non-corrosive gases requiring precise and stable pressure control, this regulator is a staple in laboratory and high-tech industrial environments. The 620 Series distinguishes itself with a two-stage design, which ensures that the outlet pressure remains constant even as the inlet pressure from the cylinder decays. This feature is critical for analytical applications where pressure fluctuations can compromise results or damage sensitive downstream equipment.

At the heart of the 620 Silverline is a unique, 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. The metal-to-metal seal between the body and the diaphragm further eliminates potential leak paths and contamination sources, making it suitable for high-purity applications. The regulator body is machined from brass bar stock and finished with nickel plating, offering a robust and corrosion-resistant exterior that withstands the rigors of industrial use while maintaining a clean aesthetic suitable for lab environments.

Safety and versatility are paramount in the 620 Series design. It features capturable vents in the bonnet (1/16" FNPT) for both stages, allowing for the safe piping of hazardous or flammable gases away from the work area in the unlikely event of a diaphragm failure. Additionally, the regulator is capable of withstanding internal vacuums, making it compatible with purging operations essential for maintaining system purity. With a delivery range of 30" HG vacuum to 30 PSIG and a maximum inlet pressure of 3500 PSIG, this regulator offers the flexibility needed for a wide range of specialty gas applications utilizing a CGA 510 connection.
