818-00090000 - Miller Smith Silverline 810 Series High Purity Piston Regulator, 500 PSI, CGA 580

Miller Smith 818-00-09-00-00 Silverline High Purity Analytical Regulator

The Miller Smith 818-00-09-00-00 is a premium component of the 810 Silverline Series, engineered specifically for high-purity analytical applications where gas integrity and precise pressure control are paramount. Constructed from high-grade brass and finished with a durable nickel plating, this single-stage regulator is designed to resist corrosion and maintain the purity of the gas stream, making it an essential tool for laboratories, research and development facilities, and chemical manufacturing environments. The nickel plating not only enhances the aesthetic but serves a critical functional role in preventing the brass substrate from interacting with the environment or the media, ensuring that the gas delivered remains free from particulate contamination.

At the core of this regulator is a robust piston sensor design. Unlike diaphragm sensors which can be sensitive to high-pressure spikes, the piston mechanism provides exceptional structural reliability, particularly when managing delivery pressures up to 500 PSI. This design choice makes the 818-00-09-00-00 particularly suitable for applications such as high-pressure testing, charging systems, and purging operations where durability is as critical as precision. The unit features a low-torque adjustment knob, allowing operators to fine-tune outlet pressure with ease, ensuring safe and accurate adjustments even in closed or dead-end systems.

Versatility in installation is a key feature of the Silverline series. The regulator body is tapped for rear panel mounting, and the bonnet is threaded for front panel mounting, providing seamless integration into control panels, gas cabinets, or benchtop setups. Safety and environmental control are addressed via the capturable vent port (1/16" FNPT) located in the bonnet, which allows users to pipe vented gases away from the work area—a critical feature when working in enclosed spaces or with specific gas mixtures. Equipped with clear, easy-to-read 2-1/2 inch single scale gauges, this regulator provides immediate visual confirmation of cylinder and delivery pressures.

This model comes equipped with a CGA 580 inlet connection, making it compatible with a wide range of inert gases including Nitrogen, Argon, and Helium. With a maximum inlet pressure rating of 3500 PSI and a delivery range of 0-500 PSI, it bridges the gap between standard industrial regulators and ultra-high-purity instrumentation, offering a cost-effective yet high-performance solution for analytical tasks.
