826-8128 - Miller Smith Silverline High Pressure Analytical Brass Regulator, 0-4000 PSI, CGA 680

Precision High-Pressure Analytical Control

The Miller Smith 826-8128 Silverline High Pressure Analytical Brass Single Stage Regulator is engineered for professionals requiring exacting control over high-pressure inert gases. Designed as part of the renowned 820 Silverline series, this regulator is specifically built to manage delivery pressures ranging from 0 to 4000 PSIG, making it an indispensable tool for specialized applications such as calibration kits, R&D laboratories, and chemical manufacturing processes. The unit features a robust piston sensor design, which offers superior structural reliability compared to traditional diaphragm mechanisms when dealing with the extreme forces associated with high-pressure cylinders.

Constructed with a nickel-plated brass body and bonnet, the 826-8128 provides excellent resistance to corrosion, extending the service life of the equipment even in industrial environments. The regulator is equipped with a CGA 680 inlet connection, suitable for high-pressure inert gas cylinders. A key feature for analytical work is the self-relieving adjusting screw. This low-torque control mechanism permits easy and precise adjustment of pressures, even in closed or dead-end systems, preventing pressure buildup and ensuring safety. Furthermore, the bonnet vent hole is tapped (1/16 inch FNPT), allowing users to install a captured vent line to safely divert gases away from the immediate work area, a critical safety feature in enclosed laboratory settings.

Visibility and ease of use are enhanced by the large 2-1/2 inch single scale gauges, which allow operators to read pressure settings accurately from a greater distance than standard 2-inch gauges. Although designed for inert gases, the regulator is 100 percent tested at maximum rated operating pressure and cleaned for oxygen service, ensuring the highest levels of cleanliness and safety. Whether used for purging, charging, or high-pressure testing, the Miller Smith 826-8128 delivers the consistent performance and reliability required for critical analytical tasks.
