121-2005 - Miller Smith Silverline 2-Stage Regulator, 0-50 PSI, CGA 346

Precision Gas Control with Miller Smith Silverline Series

The Miller Smith 121-20-05 Silverline Series General Purpose Two Stage Regulator is engineered for professionals requiring exacting control over inert and non-corrosive gases. Designed to handle Air, Nitrogen, CO2, and Argon, this regulator excels in laboratory, general plant, and maintenance shop environments where maintaining a constant delivery pressure is critical. Unlike single-stage regulators that may allow delivery pressure to rise as the cylinder pressure falls, this two-stage unit compensates for inlet pressure decay, providing a steady and reliable flow throughout the life of the cylinder.

Robust Construction and Design

Built to withstand the rigors of industrial use, the 121-20-05 features a rugged brass construction machined from bar stock. The body, bonnet, and gauges are fully plated, offering superior protection against corrosion and wear. This plating not only enhances durability but also helps maintain the cleanliness required for high-purity gas applications. The regulator incorporates a large 1-7/8 inch diaphragm, which provides exceptional sensitivity and precise control over the 0-50 PSI delivery range. The inclusion of Miller's Sure-Seat technology further enhances reliability by filtering the gas stream, protecting the seat from debris, and extending the service life of the unit.

Safety and Usability

Safety is paramount in gas regulation. This model includes a preset safety relief valve that vents to the atmosphere, ensuring the regulator remains safe for use with non-hazardous gases. The large 2-1/2 inch single scale gauges are designed for easy readability, allowing operators to monitor cylinder and delivery pressure at a glance. The body is also tapped for rear panel mounting, offering flexibility for installation in fixed systems or test benches. With a maximum inlet pressure rating of 3500 PSIG and a CGA 346 connection, this regulator is a versatile and dependable choice for compressed air and inert gas service.
