122-2006 - Miller Smith Silverline 120 Series Two-Stage Regulator CGA 350 100 PSI

Precision Control for Specialized Gases

The Miller Smith 122-20-06 Silverline Series General Purpose Two-Stage Regulator is engineered for professionals requiring exacting pressure control in laboratory, plant, and maintenance environments. Distinguished by its CGA 350 connection, this regulator is specifically configured for use with flammable gases such as Hydrogen, Methane, and Natural Gas, adhering to strict industry safety standards. Unlike single-stage counterparts, this two-stage device reduces cylinder pressure in two distinct steps, ensuring that the delivery pressure remains absolutely constant even as the cylinder pressure drops during use. This feature is indispensable for applications where pressure fluctuation could compromise process integrity or safety.

Constructed from rugged brass bar stock, the body and bonnet are plated to provide superior protection against corrosion and wear, ensuring a long service life even in demanding industrial settings. The regulator features a large 1-7/8 inch diaphragm which provides exceptional sensitivity and precise control over the 0-100 PSI delivery range. The inclusion of Sure-Seat technology and a filtered seat mechanism prevents debris from entering the seating area, significantly enhancing gas stream purity and preventing premature failure. With a maximum inlet pressure rating of 3500 PSI, it is compatible with standard high-pressure cylinders.

The unit is designed with usability in mind, featuring large 2-1/2 inch single-scale gauges that are easy to read at a glance. The body is also tapped for rear panel mounting, offering flexibility for installation in gas manifolds or fixed systems. While the Silverline series is generally described for inert gases, the specific CGA 350 fitting on this model dictates its specialized application for fuel gases like Hydrogen. Operators should always verify gas compatibility and safety protocols before use.
