823-0026 - Miller Smith 820 Series High Pressure Analytical Regulator, 0-500 PSI, CGA 347

Precision High-Pressure Control for Analytical Applications

The Miller Smith 823-00-26 Silverline High Pressure Analytical Brass Single Stage Regulator is engineered to meet the rigorous demands of laboratory and industrial testing environments. Part of the esteemed 820 Silverline series, this regulator is specifically designed to manage high inlet pressures up to 6000 PSIG while delivering a precise, stable output range of 0-500 PSIG. The core of its performance lies in its piston sensor design, which provides superior structural reliability compared to traditional diaphragm mechanisms when handling elevated pressures. This design choice ensures consistent performance during purging, charging, and calibration tasks where accuracy is paramount.

Material integrity is a focal point of the 823-00-26. The entire body, bonnet, and gauge casings are constructed from brass and finished with a durable nickel plating. This plating not only enhances the aesthetic appeal but, more importantly, offers significant protection against corrosion, extending the service life of the unit in varied environmental conditions. The regulator is cleaned for oxygen service, indicating a high level of cleanliness and suitability for high-purity applications, although it is configured with a CGA 347 connection typically used for high-pressure inert gases like nitrogen or air.

Operational safety and ease of use are integrated into every aspect of the design. The unit features a self-relieving adjusting screw that allows for low-torque pressure adjustments, even in closed or dead-end systems, reducing operator fatigue and mechanical stress on the component. For safety in enclosed spaces, the bonnet includes a 1/16-inch FNPT tapped vent hole, allowing users to install a captured vent line to direct gases away from the immediate work area. Large 2-1/2 inch single-scale gauges provide clear, legible readings from a distance, ensuring operators can monitor system status at a glance. Whether for R&D laboratories, chemical plants, or manufacturing processes, this regulator delivers the reliability required for critical high-pressure gas delivery.
