255-0000 - Miller Smith Silverline 250 Series High Purity Liquid Cylinder Regulator 0-350 PSIG

Technical Precision for High Purity Applications

The Miller Smith 255-00-00 Silverline High Purity Analytical Liquid Cylinder Regulator is engineered for the rigorous demands of laboratory and bulk gas distribution environments. Part of the renowned 250 Silverline Series, this single-stage regulator is specifically configured for gas withdrawal from liquid cylinders. It features a specialized back-mount inlet connection (1/4" FNPT) that facilitates direct and ergonomic attachment to liquid cylinder manifolds, minimizing strain on piping and connections.

At the core of this regulator's performance is a large 1-7/8 inch stainless steel diaphragm. Unlike elastomeric diaphragms, the stainless steel construction prevents off-gassing and absorption, maintaining the integrity of high-purity analytical gases. This material choice also provides extended service life in cryogenic applications where temperature fluctuations can degrade lesser materials. The regulator manages inlet pressures up to 3500 PSIG and provides a precise delivery range of 0-350 PSIG, making it suitable for a wide variety of analytical and process applications.

The unit is constructed from rugged brass bar stock but features a full nickel plating on the body, bonnet, and gauges. This plating offers superior protection against corrosion and environmental wear, essential for equipment used in industrial or 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, thereby reducing maintenance costs and downtime.
