825-8110 - Miller Smith 820 Silverline High Pressure Piston Regulator, CGA 590, 0-2000 PSI Delivery

Precision Analytical Control for High Pressure Systems

The Miller Smith 825-81-10 Silverline High Pressure Analytical Brass Single Stage Regulator is an elite instrument designed for the rigorous demands of specialty gas delivery. Engineered within the renowned 820 Silverline series, this regulator is specifically calibrated to handle non-corrosive inert gases with a delivery range of 0-2000 PSI. At the core of its performance is a robust piston sensor design. Unlike standard diaphragm models, the piston sensor provides superior structural reliability, making it the ideal choice for high-pressure applications where inlet pressures can reach up to 6000 PSI. This design ensures stable outlet pressure even as the supply cylinder depletes, maintaining the integrity of your analytical processes.

Material quality is paramount in the 825-81-10. The entire assembly—including the body, bonnet, and gauges—features a durable nickel plating. This not only gives the unit a professional aesthetic but, more importantly, protects the brass substrate from corrosion and environmental wear, significantly extending the service life of the equipment. The regulator is cleaned for oxygen service and undergoes 100% testing at maximum rated operating pressures, ensuring it meets the highest safety and performance standards required by R&D laboratories and chemical plants.

Operational precision is achieved through a low-torque control adjusting screw. This self-relieving mechanism permits effortless adjustment of pressures, even in closed or dead-end systems, preventing pressure creep and ensuring safety. For enhanced safety management, the bonnet includes a tapped 1/16-inch FNPT vent hole, allowing users to install a captured vent line to divert gases away from the immediate work area. The unit is also equipped with large 2-1/2 inch single scale gauges, which provide clear, legible readings from a distance, reducing the need for operators to be in immediate proximity to high-pressure sources.

This regulator is equipped with a CGA 590 inlet connection, typically utilized for industrial air or sulfur hexafluoride, and is tapped for rear panel mounting, offering flexibility for integration into test benches, calibration kits, and manufacturing process panels. Whether used for purging, charging, or high-pressure testing, the Miller Smith 825-81-10 delivers the reliability and accuracy essential for critical industrial and analytical tasks.
