121-2009 - Miller Smith Silverline 2-Stage Inert Gas Regulator 0-60 PSI CGA 580

Precision Control for Laboratory and Industrial Gases

The Miller Smith 121-20-09 Silverline Series General Purpose Two Stage Regulator is engineered for professionals who demand stability and purity in their gas delivery systems. Designed specifically for inert and non-corrosive gases such as Argon, Nitrogen, and Helium, this regulator features a robust two-stage mechanism. Unlike single-stage counterparts, a two-stage regulator reduces pressure in two steps, ensuring that the delivery pressure remains constant even as the cylinder pressure drops significantly during use. This feature is critical for laboratory applications, analytical testing, and precision manufacturing where pressure fluctuations can compromise results.

Constructed from rugged brass bar stock, the body and bonnet are plated to provide a clean, corrosion-resistant finish suitable for controlled environments. The heart of the regulator is its large 1-7/8 inch diaphragm, which offers exceptional sensitivity and precise control over the 0-60 PSIG delivery range. This model is equipped with Miller's proprietary Sure-Seat technology, which incorporates a filtered seat to prevent debris from entering the high-pressure stream, thereby extending the service life of the regulator and maintaining gas stream purity. The inclusion of a 1/4" MNPT needle valve allows for fine-tuning of the flow rate directly at the outlet.

Safety and ease of use are paramount in the Silverline Series. The regulator includes a preset safety relief valve that vents to the atmosphere, ensuring safe operation with non-hazardous gases. The large 2-1/2 inch single-scale gauges are easy to read, allowing operators to monitor tank and delivery pressure at a glance. Whether for gas chromatography, purging applications, or general laboratory maintenance, the Miller Smith 121-20-09 delivers the reliability and performance expected from a top-tier gas equipment manufacturer.
