OVERVIEW

Industrial Grade Reliability for Liquid Cylinders

The Miller Smith 252-82-08 Silverline Regulator represents the gold standard for managing gas delivery from liquid cylinders in industrial and bulk gas distribution settings. Built by Miller Smith, a name synonymous with quality gas equipment, this regulator is part of the 250 Silverline series, designed to bridge the gap between heavy-duty industrial tools and high-precision laboratory instruments. If your operation relies on bulk liquid oxygen supply, this regulator provides the durability and precision necessary to keep your downstream processes running smoothly.

Robust Construction & Corrosion Resistance

Industrial environments can be harsh, but the 252-82-08 is built to last. The entire exterior—body, bonnet, and gauges—is nickel-plated. This plating is not just for looks; it provides a robust shield against corrosion and wear, extending the service life of the unit even in challenging conditions. The regulator is constructed from rugged brass bar stock, ensuring it can withstand the physical demands of daily use. Furthermore, the back-entry design is specifically tailored for liquid cylinders, keeping the regulator profile compact and protecting the connection points from unnecessary strain.

Advanced Diaphragm & Seat Design

Consistency is key in welding and fabrication support. This regulator features a large 1-7/8 inch stainless steel diaphragm. Unlike neoprene or rubber diaphragms that can stiffen and crack under the cold temperatures generated by liquid cylinder gas vaporization, the stainless steel diaphragm remains flexible and accurate. This results in a steady delivery pressure of 0-100 PSIG, regardless of the cylinder's liquid level or temperature. Additionally, the unit features a built-in capturable preset safety relief valve, adding an extra layer of safety for your personnel and equipment.

Maintenance-Free Operation

Downtime is the enemy of productivity. That is why Miller Smith equipped this regulator with their proprietary Sure-Seat™ technology. By filtering out contaminants before they can damage the high-pressure seat, this regulator virtually eliminates the most common cause of regulator failure. This means fewer repairs, fewer replacements, and more uninterrupted work. With a CGA 540 inlet for oxygen and a max inlet rating of 3500 PSI, the Miller Smith 252-82-08 is the professional's choice for reliable, high-purity gas regulation from liquid sources.

FAQ

The Miller Smith 252-82-08 is rated for a maximum inlet pressure of 3500 PSIG.

This regulator is designed to control the delivery of gas, not liquid. It connects to the gas use valve of a liquid cylinder (dewar) to regulate the vaporized gas pressure.

The CGA 540 connection is the standard standard for Oxygen service in the United States.

A stainless steel diaphragm is used because it provides superior performance in cryogenic applications. It withstands the cold temperatures associated with liquid cylinders better than elastomers and ensures high purity by not off-gassing.

This regulator has a delivery pressure range of 0-100 PSIG.

The nickel plating on the body, bonnet, and gauges protects the regulator from corrosion, extends its service life, and helps maintain the purity of the environment by preventing brass oxidation.

While the CGA 540 fitting will physically connect to a standard oxygen cylinder, the regulator is 'back mount' (rear entry) designed specifically for the geometry of liquid cylinders. Using it on a standard cylinder may result in the gauges facing an awkward direction.

Sure-Seat is a filtered seat design exclusive to Smith Equipment. It prevents contamination from entering the seating area, which is the leading cause of regulator creep and failure.
