825-0008 - Miller Smith 820 Silverline High Pressure Oxygen Regulator, 0-2000 PSI Delivery

Technical Overview of the Miller Smith 825-00-08

The Miller Smith 825-00-08 is a premium component within the 820 Silverline Series, engineered specifically for high-pressure analytical and industrial applications. This single-stage regulator is distinguished by its robust piston sensor design, which replaces the traditional diaphragm mechanism found in lower-pressure units. The piston configuration provides exceptional structural reliability, enabling the unit to safely handle maximum inlet pressures of up to 6000 PSIG while maintaining a stable delivery pressure range of 0-2000 PSIG. This makes it an ideal solution for demanding environments such as R&D laboratories, chemical plants, and high-pressure testing facilities.

Constructed from high-quality brass, the regulator features a full nickel plating on the body, bonnet, and gauges. This plating serves a dual purpose: it enhances the aesthetic appearance of the equipment and, more importantly, provides a significant layer of protection against corrosion, extending the service life of the unit in varied atmospheric conditions. The regulator is equipped with a CGA 540 connection, designating it for use with Oxygen, and is cleaned for oxygen service according to strict industry standards. The outlet configuration is a 1/4" FNPT, allowing for versatile integration into panel mounts or custom piping systems.

Operational precision is achieved through a low-torque control adjusting screw, which is self-relieving. This feature is critical for closed or dead-end systems, allowing users to reduce pressure settings without venting the downstream line manually. Safety and monitoring are further enhanced by the inclusion of large 2-1/2 inch single-scale gauges, which provide clear visibility of cylinder and delivery pressures. Additionally, the bonnet includes a 1/16" FNPT tapped vent hole, facilitating the installation of a captured vent line to safely divert gases away from the immediate work area, a crucial compliance feature for indoor laboratory settings.
