121-2006 - Miller Smith Silverline 120 Series Two-Stage Regulator CGA 350 0-60 PSI

Precision Control with Miller Smith Silverline Series

The Miller Smith 121-20-06 Silverline Series General Purpose Two Stage Regulator is engineered for applications requiring unwavering delivery pressure and exceptional durability. Designed as part of the renowned Silverline 120 Series, this regulator utilizes a true two-stage design. This configuration drops cylinder pressure in two steps, ensuring that the delivery pressure remains constant throughout the life of the cylinder, regardless of fluctuations in inlet pressure. This feature is critical for laboratory, analytical, and precise manufacturing environments where consistency is paramount.

Robust Construction and Sure-Seat Technology

Built to withstand the rigors of general plant and maintenance shop environments, the 121-20-06 features a rugged brass bar stock body and bonnet. The entire assembly is plated to provide superior protection against corrosion and wear. At the heart of the regulator is Miller Smith's proprietary Sure-Seat technology. This filtered seat design prevents debris and particulates from entering the high-pressure seat area, a common cause of regulator failure. By filtering the gas stream, the regulator ensures purity and significantly extends the service life of the component.

Specifications and Performance

This model is equipped with a CGA 350 inlet connection, making it suitable for gases such as Hydrogen, Methane, and other compatible media (users should always verify gas compatibility with the CGA standard). It offers a delivery pressure range of 0-60 PSI, controlled via a large 1-7/8 inch diaphragm that provides sensitive response to adjustment. The unit includes two large 2-1/2 inch single-scale gauges that are easy to read at a glance. With a maximum inlet pressure rating of 3500 PSI, it is ready for high-pressure cylinders. The body is also tapped for rear panel mounting, offering versatility for fixed installations.
