100-0000 - Miller Smith Silverline 100 Series Line Regulator 0-15 PSI

Technical Analysis: Miller Smith 100-00-00 Silverline Regulator

The Miller Smith 100-00-00 is a single-stage line regulator from the renowned Silverline Series, engineered specifically for the control of inert and non-corrosive gases including Air, Nitrogen, CO2, and Argon. Designed for installation downstream from a high-pressure source—such as a bulk tank or manifold system—this unit manages inlet pressures up to 1200 PSIG, reducing them to a stable working pressure range of 0-15 PSIG. The regulator features 1/4" FNPT inlet and outlet connections, making it compatible with standard industrial piping and hose fittings.

Internally, the regulator utilizes a large 1-7/8 inch diaphragm. This diaphragm size is critical for maintaining consistent delivery pressure even as flow demand fluctuates, providing adequate sensitivity for general purpose applications. The unit incorporates Miller's proprietary Sure-Seat technology. This filtered seat design is a significant technical advantage, as it prevents the ingress of particulate matter into the high-velocity seating area, thereby preventing seat degradation and creep. This feature is particularly valuable in shop environments where gas purity at the station drop cannot always be guaranteed.

Construction-wise, the 100-00-00 is built from rugged brass bar stock, ensuring structural integrity and resistance to deformation under pressure. The body, bonnet, and gauges are plated to provide superior protection against environmental corrosion. The 2-1/2 inch single-scale gauges offer clear readability, allowing operators to monitor pressure at a glance. While not intended for high-purity applications requiring minimal inboard diffusion, this regulator excels in standard industrial MRO, fabrication, and laboratory support roles where reliable, low-pressure gas delivery is required.
