827-6609 - Miller Smith 820 Silverline High Pressure Piston Regulator 0-6000 PSI CGA 580

Precision High-Pressure Control for Analytical Applications

The Miller Smith 827-66-09 Silverline High Pressure Analytical Brass Single Stage Regulator is engineered to meet the rigorous demands of specialty gas delivery. Designed specifically for non-corrosive inert gases such as Argon, Nitrogen, and Helium, this regulator is a staple in R&D laboratories, chemical plants, and high-pressure testing facilities. Its robust construction and precise engineering make it the ideal choice for applications requiring delivery pressures up to 6000 PSIG.

At the core of the 827-66-09 is a reliable piston sensor design. Unlike diaphragm regulators which can be sensitive to extreme pressures, the piston mechanism provides superior structural integrity, ensuring consistent performance even at the maximum rated inlet pressure of 6000 PSI. This design is particularly beneficial for purging, charging, and calibration kits where reliability is paramount. The regulator is also 100% tested at maximum operating pressure, giving operators confidence in its safety and performance.

Durability and cleanliness are key features of the Silverline series. The entire assembly—including the body, bonnet, and gauges—is nickel-plated. This plating not only gives the regulator a professional aesthetic but, more importantly, protects the brass substrate from corrosion, significantly extending the service life of the unit. Furthermore, although intended for inert gases via the CGA 580 connection, the regulator is cleaned for oxygen service, ensuring a high level of cleanliness that minimizes contamination risks in analytical workflows.

Operator safety and ease of use have been thoughtfully integrated into the design. The unit features a self-relieving adjusting screw that permits easy, low-torque adjustment of pressures, even in closed or dead-end systems. For environments where gas venting is a concern, the bonnet includes a 1/16-inch FNPT tapped vent hole, allowing for the installation of a captured vent line to safely direct gases away from the work area. Large 2-1/2 inch single-scale gauges ensure that pressure readings are legible from a distance, enhancing operational efficiency.
