823-0000 - Miller Smith 820 Series Silverline Piston Regulator 0-500 PSIG

Precision Control for Analytical Applications

The Miller Smith 823-00-00 Silverline High Pressure Analytical Brass Single Stage Regulator is engineered to meet the rigorous demands of laboratory and analytical environments. Part of the esteemed 820 Silverline series, this regulator is designed specifically to manage high pressures from a wide variety of non-corrosive inert gases. With a delivery range of 0-500 PSIG and a maximum inlet pressure capability of 6000 PSIG, it stands as a robust solution for applications requiring substantial pressure reduction without compromising on stability or precision.

At the core of this regulator is a piston sensor design. Unlike traditional diaphragm sensors, the piston mechanism provides exceptional structural reliability, particularly when dealing with the mechanical stresses of high-pressure inputs. This design choice ensures consistent performance and longevity, even in high-cycle environments such as calibration kits and R&D laboratories. The unit is constructed from brass but features a high-quality nickel plating on the body, bonnet, and gauges. This plating not only provides a professional, clean aesthetic suitable for lab settings but also offers superior protection against corrosion, extending the service life of the equipment.

Safety and adaptability are paramount in analytical settings. The 823-00-00 addresses these needs with a self-relieving adjusting screw, which allows for low-torque pressure adjustments even in closed or dead-end systems. Furthermore, the bonnet includes a capturable vent port (1/16" FNPT), allowing users to pipe vented gases away from the immediate work area—a critical feature for maintaining safe atmospheric conditions in enclosed spaces. The regulator is also cleaned for oxygen service and 100% tested at maximum rated operating pressures, ensuring it meets strict safety standards right out of the box.

Installation flexibility is provided via 1/4" FNPT inlet and outlet connections, allowing for custom fittings or hard piping as required by the specific gas delivery system. The body is also tapped for rear panel mounting, making it an excellent choice for integrated control panels or fixed instrumentation setups. Large 2-1/2 inch single scale gauges provide clear, at-a-glance readings, reducing the risk of parallax errors and enhancing workflow efficiency.
