611-00000000 - Miller Smith 610 Series High Purity Brass Regulator, 0-50 PSI Delivery, 1/4 FNPT

Precision Control for High Purity Applications

The Miller Smith 611-00-00-00-00 Silverline High Purity Brass Single Stage Regulator is engineered specifically for analytical and process applications where maintaining gas stream integrity is paramount. Part of the renowned 610 Series Silverline, this regulator is designed to prevent contamination in high-purity systems, making it an essential component for laboratory instrumentation, gas chromatography, and other sensitive environments utilizing non-corrosive gases.

At the core of this regulator's performance is its stainless steel diaphragm. Unlike elastomeric diaphragms that can absorb and release contaminants (off-gassing) or allow diffusion, the stainless steel construction provides a hermetic barrier that preserves the purity of the gas being regulated. This is complemented by a metal-to-metal seal between the body and the diaphragm, eliminating the need for gaskets that could degrade over time or introduce impurities. The regulator also features a filtered seat and a 316 stainless steel filter, further ensuring that particulate matter does not compromise the downstream equipment or the regulator's internal mechanisms.

The body is machined from brass bar stock and nickel-plated, offering a robust housing that resists environmental corrosion while maintaining a clean aesthetic suitable for laboratory settings. The unit is designed with versatility in mind, featuring 1/4" FNPT inlet and outlet ports rather than fixed CGA connections, allowing for customized plumbing into panels or line systems. It is fully capable of withstanding an internal vacuum, which is critical for purge cycles in high-purity lines. Additionally, the bonnet is threaded and the body tapped for rear panel mounting, providing secure and professional installation options.

Safety and precision are integrated into every aspect of the design. The 2-1/2 inch single scale gauge provides clear, accurate readings of delivery pressure within the 0-60 PSI range. A capturable vent in the bonnet (1/16" FNPT) allows for the safe piping away of hazardous gases in the unlikely event of a diaphragm failure, ensuring operator safety in enclosed environments.
