Miller Smith 820 Silverline High Pressure Piston Regulator, 0-2000 PSI, CGA 347

Miller Smith 820 Silverline: Reliability Under Pressure

Welders Supply is proud to offer the Miller Smith 825-66-26, a premium high-pressure regulator from the trusted 820 Silverline series. Designed for professionals who demand accuracy and durability, this single-stage regulator is optimized for analytical and high-pressure applications involving non-corrosive inert gases. It features a CGA 347 inlet connection and is rated for a maximum inlet pressure of 6000 PSIG, with a delivery pressure range of 0-2000 PSIG.

The core of this regulator's performance lies in its piston sensor design. Piston sensors are preferred for high-pressure applications because they offer greater structural integrity compared to traditional diaphragms, reducing the risk of failure under heavy loads. This makes the 825-66-26 an excellent choice for calibration kits, high-pressure testing, and system purging. The entire unit—including the body, bonnet, and gauges—is nickel-plated. This not only gives it a distinctive silver appearance but also provides a robust shield against corrosion and wear, ensuring long-term reliability.

Operational efficiency is enhanced by the low-torque control adjusting screw, which is self-relieving to permit easy pressure reduction in closed systems without the need to bleed the line manually. The regulator is also equipped with large, easy-to-read 2-1/2 inch gauges, allowing operators to monitor cylinder and delivery pressures accurately at a glance. For installations requiring fixed positioning, the body is tapped for rear panel mounting, offering flexibility in system integration.

Safety and compliance are built into every unit. The bonnet includes a capturable vent port (1/16" FNPT) to vent gases away from the user, a critical feature for enclosed environments. All regulators are cleaned for oxygen service and undergo rigorous testing to ensure they handle the rated pressures safely. Choose the Miller Smith 825-66-26 for a high-performance solution that combines the strength of brass with the resilience of nickel plating and the precision of piston technology.
