213-0000 - Miller Smith 210 Series Silverline Analytical Regulator, 0-150 PSI, 1/4 FNPT

Precision Control for Analytical Applications

The Miller Smith 213-00-00 Silverline High Purity Analytical Single Stage Regulator is a premium gas control device engineered specifically for applications where gas purity is paramount. Part of the renowned 210 Silverline Series, this regulator bridges the gap between standard industrial regulators and ultra-high purity stainless steel models. It is constructed from rugged brass bar stock but features a fully plated body, bonnet, and gauges. This plating not only provides an aesthetic finish but also offers superior protection against external corrosion and wear, ensuring the unit maintains its integrity in laboratory and industrial environments.

At the heart of the 213-00-00 is a stainless steel diaphragm. Unlike neoprene or rubber diaphragms found in general-purpose regulators, the stainless steel construction prevents the absorption and release of atmospheric contaminants (outgassing) into the gas stream. This feature is critical for analytical instruments, gas chromatography, and biological laboratory applications where even trace impurities can skew results. The regulator also incorporates a filtered seat mechanism, which adds another layer of protection for the gas stream while extending the service life of the internal components by preventing particulate damage.

Designed for versatility, this model comes equipped with 1/4" FNPT (Female National Pipe Thread) inlet and outlet ports rather than fixed CGA cylinder connections. This configuration allows technicians and engineers to adapt the regulator for rear panel mounting, line regulation, or custom cylinder connections using specific pigtails. With a maximum inlet pressure rating of 3500 PSI and a delivery range of 0-150 PSI, it is robust enough to handle high-pressure sources while delivering steady downstream flow. The unit is also capable of withstanding vacuums generated during purging operations, making it highly effective for systems requiring strict atmosphere control.

Safety and ease of use are integral to the design. The regulator features a built-in capturable preset safety relief valve, which protects downstream equipment from over-pressurization. The large, 2-1/2 inch single scale gauges are easy to read, allowing operators to monitor tank and delivery pressure at a glance. Whether used in automotive emissions testing, chemical process plants, or research laboratories, the Miller Smith 213-00-00 delivers reliable, high-purity performance for non-corrosive gases.
