255-0008 - Miller Smith 250 Series Silverline High Purity Liquid Cylinder Regulator CGA 540

High Purity Precision for Analytical Applications

The Miller Smith 255-00-08 Silverline High Purity Analytical Liquid Cylinder Regulator is a premium gas control solution designed specifically for the rigorous demands of laboratory and analytical environments. Part of the esteemed 250 Silverline series, this single-stage regulator is engineered to maintain gas purity while providing precise pressure control. It features a specialized rear-mount inlet configuration, making it the ideal choice for direct connection to liquid cylinders (dewars) where traditional side-entry regulators would be awkward or unsafe to install.

At the heart of this regulator is a large 1-7/8 inch stainless steel diaphragm. Unlike neoprene or rubber diaphragms, stainless steel prevents off-gassing and absorption, ensuring that the high purity gas stream remains uncontaminated during regulation. This makes the 255-00-08 particularly suitable for analytical instruments where even trace impurities can skew results. The regulator is capable of handling inlet pressures up to 3500 PSI and delivers a consistent outlet pressure ranging from 0 to 350 PSI, accommodating a wide variety of application requirements.

Durability and longevity are key components of the Miller Smith design. The entire body, bonnet, and gauge cases are nickel-plated, offering exceptional resistance to corrosion and wear. This plating not only protects the brass bar stock construction but also helps maintain a clean, professional appearance in laboratory settings. The regulator also incorporates Smith's exclusive Sure-Seat™ technology. This filtered seat design prevents particulate contamination from entering the high-pressure seating area, a common cause of regulator failure. By filtering out debris, the Sure-Seat significantly reduces repair costs and downtime, ensuring reliable performance over the long term.

For ease of use, the unit is equipped with large 2-1/2 inch single scale gauges that are easy to read from a distance. The outlet connection is a standard 1/4" FNPT, allowing for versatile integration with various piping and instrumentation setups. Whether used for bulk gas distribution or direct instrument supply, the Miller Smith 255-00-08 delivers the reliability and purity required by professionals.
