621-40060000 - Miller Smith Silverline 620 Series High Purity Two-Stage Regulator, CGA 350, 0-60 PSI

Precision Control for Specialty Gases

The Miller Smith Silverline 620 Series High Purity Two-Stage Regulator is a premium solution designed for the precise management of non-corrosive specialty gases. Engineered with the needs of analytical laboratories and high-tech manufacturing in mind, this regulator combines robust construction with sensitive control mechanisms. The unit features a CGA 350 inlet connection, making it compatible with gases such as hydrogen and methane, and offers a delivery pressure range of 0-60 PSI.

Uncompromised Purity

Maintaining gas purity is critical in chromatography and other analytical processes. The Silverline 620 addresses this with a 316 stainless steel filter at the seat to trap particulates and a stainless steel diaphragm that prevents off-gassing and diffusion. The metal-to-metal seal between the body and the diaphragm ensures a leak-tight enclosure, capable of withstanding internal vacuums during purging operations. This design eliminates the use of elastomeric seals in the gas stream, significantly reducing the risk of sample contamination.

Stable and Safe Operation

As a two-stage regulator, the 621-40-06-00-00 provides a constant outlet pressure regardless of fluctuations in the supply cylinder. This stability is essential for long-duration tests and processes where pressure drift could compromise results. Safety is also paramount; the regulator includes captured 1/16" FNPT vent ports on the bonnet, allowing hazardous gases to be piped away safely in the event of a diaphragm failure. The nickel-plated brass bar stock body ensures long-term durability while maintaining a clean, professional appearance suitable for laboratory environments.
