123-0009 - Miller Smith Silverline 2-Stage Inert Gas Regulator, 0-250 PSI Delivery, CGA 580

Precision Control for Inert Gas Applications

The Miller Smith 123-00-09 Silverline Series General Purpose Two Stage Regulator is engineered for professionals requiring exacting pressure control in laboratory, testing, and industrial environments. Designed specifically for inert and non-corrosive gases such as Air, Nitrogen, Carbon Dioxide (CO2), and Argon, this regulator exemplifies Miller Smith's commitment to quality and precision. The unit features a robust two-stage design, which is critical for applications where a constant delivery pressure is mandatory. Unlike single-stage regulators that may allow delivery pressure to fluctuate as the supply cylinder empties, the 123-00-09 maintains a steady 0-250 PSI output throughout the life of the cylinder, ensuring process consistency and data integrity.

Advanced Construction and Durability

Built to withstand the rigors of daily industrial use, the regulator boasts a rugged brass bar stock body and bonnet. This solid construction minimizes potential leak paths and provides superior resistance to physical impact compared to forged or die-cast alternatives. The body, bonnet, and gauges are fully plated, offering enhanced protection against corrosion and environmental wear. Inside, the regulator utilizes Sure-Seat technology, which incorporates a filtered seat to prevent debris from entering the seating area. This feature significantly extends the service life of the component and ensures the purity of the gas stream, a vital factor for analytical and high-purity applications.

Operational Specifications

The Miller Smith 123-00-09 is equipped with a CGA 580 inlet connection, making it compatible with standard inert gas cylinders. It handles a maximum inlet pressure of 3500 PSI, accommodating modern high-pressure tanks. The large 1-7/8 inch diaphragm provides exceptional sensitivity, allowing for precise adjustments within the 0-250 PSI delivery range. Operators can easily monitor system status via the large, easy-to-read 2-1/2 inch single scale gauges. A preset safety relief valve vents to the atmosphere, adding an essential layer of safety for non-hazardous gas applications. Whether used for pneumatic testing, blanketing, or analytical instrumentation, this Silverline Series regulator delivers the reliability and performance demanded by technical professionals.
