825-6609 - Miller Smith 820 Silverline Series High Pressure Regulator, CGA 580, 0-2000 PSI

Miller Smith 825-66-09 Silverline High Pressure Regulator Overview

The Miller Smith 825-66-09 is a premium component within the 820 Silverline series, specifically engineered for high-pressure analytical and process applications. Designed to handle non-corrosive inert gases, this single-stage regulator combines robust construction with precise control mechanisms. It is an essential tool for professionals in R&D laboratories, chemical plants, and high-pressure testing facilities who require reliable gas delivery at elevated pressures.

Advanced Piston Sensor Technology

Unlike traditional diaphragm regulators, the 825-66-09 utilizes a piston sensor design. This architecture provides superior structural reliability, particularly when operating at high pressures. The piston mechanism ensures stable delivery pressures even as the inlet pressure fluctuates, making it ideal for critical applications such as calibration kits and system purging. With a maximum inlet pressure rating of 6000 PSIG, this regulator is built to withstand the rigors of heavy-duty industrial cylinders and manifold systems.

Durable and Safe Construction

Durability is a hallmark of the Silverline series. The regulator features a brass body, bonnet, and gauges that are fully nickel-plated. This plating offers exceptional protection against corrosion, extending the service life of the unit in challenging environments. Safety is also prioritized with a captured vent port in the bonnet (1/16" FNPT), allowing users to pipe vented gases away from the work area—a critical feature for enclosed or sensitive environments. Additionally, the unit is cleaned for oxygen service, ensuring a high level of cleanliness, although the CGA 580 connection is standard for inert gases like Argon, Nitrogen, and Helium.

Precision Control and Monitoring

Operators will appreciate the low-torque control adjusting screw, which is self-relieving. This feature permits easy and precise adjustment of delivery pressure, even in closed or dead-end systems, reducing operator fatigue and improving process efficiency. The regulator is equipped with large 2-1/2 inch single-scale gauges, providing clear and accurate readings of both cylinder and delivery pressures from a distance. The delivery range of 0-2000 PSIG covers a broad spectrum of high-pressure requirements, making this a versatile choice for specialized gas delivery.
