826-6600 - Miller Smith 820 Silverline High Pressure Analytical Regulator, 0-4000 PSI, 1/4 FNPT

Precision High-Pressure Control for Analytical Applications

The Miller Smith 826-66-00 Silverline High Pressure Analytical Regulator is a premium gas control device engineered for environments demanding rigorous pressure management and structural integrity. Part of the renowned 820 Silverline Series, this single-stage regulator is specifically designed to handle non-corrosive inert gases in high-pressure scenarios, making it an indispensable tool for R&D laboratories, chemical plants, and advanced manufacturing processes. Its core mechanism utilizes a robust piston sensor design, which provides superior reliability and durability compared to traditional diaphragm systems when operating at elevated pressures.

Constructed with a nickel-plated brass body and bonnet, the 826-66-00 is built to resist corrosion and maintain a pristine appearance over an extended service life. This plating is particularly beneficial in laboratory settings where cleanliness and equipment longevity are paramount. The regulator is capable of accepting a maximum inlet pressure of 6000 PSIG and provides a controllable delivery range of 0 to 4000 PSIG. This wide range makes it highly versatile for applications such as purging and charging, high-pressure testing, and the operation of calibration kits. The unit comes equipped with 1/4" FNPT inlet and outlet connections, allowing for seamless integration into standard high-pressure piping systems or custom panel setups.

Operational safety and ease of use are central to the design. The regulator features a self-relieving adjusting screw, which permits low-torque pressure adjustments even in closed or dead-end systems, preventing pressure buildup and ensuring smooth operation. For enhanced safety, the bonnet includes a tapped 1/16" FNPT vent hole, allowing users to install a captured vent line to direct gases away from the immediate work area. Additionally, the large 2-1/2 inch single-scale gauges provide clear, accurate readings from a distance, reducing the need for operators to be in close proximity during high-pressure adjustments. Whether used for component testing or precise gas delivery, the Miller Smith 826-66-00 delivers the consistency and safety required by analytical professionals.
