254-0000 - Miller Smith Silverline 250 Series High Purity Liquid Cylinder Regulator 0-200 PSIG

Precision Control for Analytical Applications

The Miller Smith 254-00-00 Silverline High Purity Analytical Liquid Cylinder Regulator is engineered to meet the rigorous demands of laboratory and specialty gas applications. As part of the esteemed Silverline 250 Series, this single-stage regulator is specifically designed for use with liquid cylinders, offering a seamless rear-entry configuration that simplifies connection and reduces strain on piping systems. In environments where gas purity is paramount, such as chromatography, spectrometry, and bulk gas distribution, the 254-00-00 stands out as a reliable solution for maintaining the integrity of your process gases.

Advanced Contamination Prevention

One of the critical challenges in high-purity gas handling is preventing contamination from the regulator itself or the surrounding environment. This Miller Smith regulator addresses this with a nickel-plated brass body, bonnet, and gauges. This plating not only provides an aesthetically professional finish but, more importantly, offers superior protection against corrosion and oxidation, ensuring that the regulator does not introduce particulate matter into the gas stream. Furthermore, the regulator features Smith’s exclusive Sure-Seat™ filtered seat technology. This innovative design incorporates a filter directly into the seating area, preventing microscopic debris from damaging the seat or entering the downstream flow, thereby extending the service life of the unit and reducing costly downtime for repairs.

Optimized for Cryogenic Service

Liquid cylinders often present unique challenges due to the low temperatures associated with cryogenic gases. The 254-00-00 is equipped with a large 1-7/8 inch stainless steel diaphragm. Unlike elastomeric diaphragms that can become brittle or permeable at low temperatures, stainless steel maintains its flexibility and integrity, providing precise pressure control even in cryogenic applications. This metal-to-metal seal integrity is essential for preventing atmospheric contamination and ensuring a constant delivery pressure of 0-200 PSIG, regardless of minor fluctuations in inlet pressure.

User-Friendly Design and Safety

Safety and ease of use are built into every aspect of this regulator. It features large 2-1/2 inch single scale gauges that are easy to read from a distance, allowing technicians to monitor cylinder and delivery pressures quickly. The unit is constructed from rugged brass bar stock for durability and includes a built-in capturable preset safety relief valve to protect downstream equipment from over-pressurization. With 1/4" FNPT inlet and outlet connections, this regulator offers versatility for custom fitting configurations in complex laboratory setups.
