The Miller Smith 121-00-06 is a premium component within the Silverline 120 Series, engineered specifically for the precise control of inert and non-corrosive gases. This unit is a two-stage regulator, a design architecture chosen for its ability to maintain a constant delivery pressure despite the inevitable decay in inlet pressure as the supply cylinder empties. This feature is critical in laboratory settings and precision maintenance applications where pressure fluctuation can compromise process integrity. The regulator is configured with a CGA 350 inlet connection, rated for a maximum inlet pressure of 3500 PSIG, and provides a delivery range of 0-60 PSIG.
Construction of the 121-00-06 utilizes a rugged brass bar stock body, ensuring high structural integrity and resistance to deformation under pressure. The body, bonnet, and gauges are plated to provide superior protection against environmental corrosion and wear. Internally, the regulator features a large 1-7/8 inch diaphragm which enhances sensitivity and response to pressure changes, allowing for fine-tuned control. The unit also incorporates Miller's proprietary Sure-Seat technology, which utilizes a filtered seat design. This filtration system prevents particulate contamination from entering the high-velocity gas stream, thereby protecting the seat from erosion and significantly extending the service life of the regulator.
The gauge assembly consists of large, 2-1/2 inch easy-to-read single scale gauges that allow operators to monitor both cylinder and delivery pressure at a glance. The body includes tapping for rear panel mounting, facilitating integration into fixed gas distribution panels or bench setups. A preset safety relief valve is integrated into the design, venting to the atmosphere to prevent over-pressurization; consequently, this regulator is strictly designated for non-hazardous gases such as Air, Nitrogen, CO2, and Argon. It is not recommended for applications requiring ultra-high purity where inboard diffusion of air or outgassing of elastomeric components is a concern.
