612-00090000 - Smith Silverline 610 Series High Purity Regulator CGA 580

Technical Overview

The Miller Smith 612-00-09-00-00 is a premium component within the Silverline 610 Series, engineered specifically for high-purity gas delivery systems. This single-stage regulator is constructed from brass nickel-plated bar stock, providing a robust housing that resists environmental corrosion while maintaining a high degree of internal cleanliness. It is designed to handle non-corrosive gases such as Argon, Nitrogen, and Helium, utilizing a CGA 580 inlet connection.

Construction and Purity

Central to the 612-00-09-00-00's performance is its stainless steel diaphragm. Unlike elastomeric diaphragms which can absorb and release contaminants, the stainless steel construction ensures a non-permeable barrier, preserving the integrity of the gas stream. The regulator features a metal-to-metal body-to-diaphragm seal, eliminating the need for gaskets that could degrade or off-gas over time. A 316 stainless steel filter is integrated into the inlet to trap particulates, further protecting the seat and downstream equipment. The seat itself is filtered, adding another layer of defense against impurities.

Performance Specifications

This model is rated for a maximum inlet pressure of 3500 PSI and provides a delivery pressure range of 0-100 PSI. It is equipped with a 2-1/2 inch single scale gauge for clear pressure monitoring. The bonnet includes a 1/16 inch FNPT port, allowing for the capture and venting of gases in the unlikely event of a diaphragm failure, a critical safety feature for laboratory and industrial environments. The outlet connection is a 1/4 inch FNPT, offering versatility for various piping and instrumentation configurations.

Applications

The Silverline 610 Series is ideal for analytical instrumentation, gas chromatography, and other applications requiring stable pressure regulation without contamination. Its packless diaphragm outlet valve (if equipped/configured) and rigorous construction standards make it a reliable choice for maintaining system purity in specialty gas delivery.
