826-0000 - Miller Smith 820 Silverline High Pressure Piston Regulator, 0-4000 PSIG, 1/4 FNPT

Precision High-Pressure Control for Analytical Applications

The Miller Smith 826-00-00 Silverline High Pressure Analytical Brass Single Stage Regulator is engineered for professionals who demand exact control over high-pressure gas delivery. Part of the renowned 820 Silverline series, this regulator is specifically designed to manage non-corrosive inert gases in critical environments such as R&D laboratories, chemical plants, and high-pressure testing facilities. With a delivery range of 0-4000 PSIG and a maximum inlet pressure of 6000 PSIG, it is built to handle substantial pressure loads that standard diaphragm regulators cannot support.

At the core of the 826-00-00 is a robust piston sensor design. Unlike rubber diaphragms which can fail under extreme high-pressure delivery conditions, the piston mechanism provides superior structural reliability and consistent performance. This design ensures that the regulator maintains stable pressure output even during demanding purging, charging, or calibration operations. The unit is equipped with 1/4-inch FNPT inlet and outlet connections, allowing for versatile plumbing configurations, including rear panel mounting for integrated system setups.

Durability and ease of maintenance are key features of this model. The entire body, bonnet, and gauges are nickel-plated, offering exceptional protection against corrosion and extending the service life of the equipment. The regulator features a self-relieving adjusting screw with low torque control, permitting easy and precise pressure adjustments even in closed or dead-end systems. Additionally, the bonnet includes a capturable vent port (1/16 inch FNPT), allowing users to pipe vented gases away from the work area safely. Cleaned for oxygen service and 100% tested at maximum operating pressure, this regulator represents the gold standard in high-pressure gas control.
