620-01090000 - Miller Smith 620 Series Silverline High Purity Two-Stage Regulator, CGA 580, 0-30 PSI

Precision Control for High Purity Applications

The Miller Smith 620 Series Silverline High Purity Brass Two-Stage Regulator is engineered for professionals who demand exacting standards in gas delivery. Designed specifically for non-corrosive specialty gases, this regulator combines the durability of brass with the purity features typically reserved for stainless steel units. The core of its performance lies in its two-stage construction, which provides a constant delivery pressure regardless of fluctuations in the inlet pressure. This is critical for analytical applications where a drop in cylinder pressure could otherwise skew results or disrupt sensitive processes.

Advanced Material Construction

Purity is paramount in the 620 Series. The regulator features a stainless steel diaphragm that offers superior chemical resistance and eliminates the outgassing associated with elastomeric diaphragms. A metal-to-metal seal between the body and the diaphragm further ensures the integrity of the gas stream. The body itself is machined from brass bar stock and finished with nickel plating, providing a robust, corrosion-resistant exterior that maintains a clean appearance in laboratory environments. Additionally, a 316 stainless steel filter is integrated into the seat to trap particulates, extending the service life of the regulator and protecting downstream equipment.

Safety and Versatility

Safety is built into the design with capturable vents in the bonnet (1/16" FNPT). In the unlikely event of a diaphragm failure, hazardous gases can be piped away safely, making this unit suitable for a wider range of lab environments. The regulator is also designed to withstand internal vacuums, facilitating effective purging operations without damage. With a delivery range of 30" Hg vacuum to 30 PSIG and a maximum inlet of 3500 PSIG, it is perfectly suited for applications such as gas chromatography, emission monitoring systems, and research laboratories utilizing inert gases like Argon, Nitrogen, or Helium via the CGA 580 connection.
