120-8406 - Miller Smith Silverline 2-Stage Hydrogen/Methane Regulator 15 PSI

Precision Gas Control with Miller Smith Silverline

The Miller Smith 120-84-06 Silverline Series Regulator is a premium two-stage gas control device engineered for applications requiring absolute pressure stability. Unlike single-stage regulators that allow delivery pressure to rise as the cylinder pressure decays, this two-stage unit maintains a constant output pressure throughout the life of the cylinder. This feature is critical in laboratory settings, analytical instrumentation, and precise manufacturing processes where flow fluctuations cannot be tolerated.

Constructed from rugged brass bar stock, the body and bonnet are nickel-plated to provide superior protection against corrosion and wear, extending the service life of the unit in industrial environments. The regulator features a large 1-7/8 inch diaphragm which offers exceptional sensitivity, allowing for fine adjustments within the 0-15 PSI delivery range. The incorporation of Miller's Sure-Seat technology, which includes a filtered seat, ensures gas stream purity by trapping debris before it can damage the seating surface or contaminate downstream equipment.

This specific model, SKU 120-84-06, is configured with a CGA 350 inlet connection, making it specifically suitable for Hydrogen, Methane, Carbon Monoxide, and other compatible fuel gases. It is rated for a maximum inlet pressure of 3500 PSIG. The outlet is equipped with a standard 9/16-18 Left Hand thread, adhering to safety standards for fuel gas connections. Large 2-1/2 inch single-scale gauges provide clear, easy-to-read pressure monitoring for both cylinder contents and delivery pressure.

Whether used for chromatography, laser mixtures, or general plant maintenance involving specific fuel gases, the Miller Smith 120-84-06 delivers the reliability and precision associated with the Silverline brand. The unit is also tapped for rear panel mounting, offering versatility for installation in gas cabinets or benchtop setups.
