Miller Smith 121-05-10 Silverline Series Two-Stage Regulator

The Miller Smith 121-05-10 is a premium General Purpose Two-Stage Regulator from the renowned Silverline 120 Series. Engineered for precision and durability, this regulator is specifically configured for Inert and non-corrosive gas applications, featuring a CGA 590 inlet connection tailored for Industrial Air. The unit is constructed from rugged brass bar stock, ensuring it can withstand the rigors of general plant and maintenance shop environments while maintaining laboratory-grade performance.

At the core of this regulator is a large 1-7/8 inch diaphragm which provides exceptional sensitivity and precise control over delivery pressure, ranging from 0 to 60 PSIG. The two-stage mechanism is a critical feature for professionals requiring consistent performance; it automatically compensates for the drop in cylinder pressure as the gas is consumed, delivering a steady flow without the need for constant manual adjustment. This makes it superior to single-stage alternatives in applications where pressure stability is paramount.

The 121-05-10 is built with Miller's proprietary Sure-Seat technology, which enhances seat integrity and gas purity. A filtered seat adds an extra layer of protection, preventing debris from the gas stream from damaging internal components. The body, bonnet, and 2-1/2 inch gauges are fully plated to resist corrosion and wear. Additionally, the body is tapped for rear panel mounting, offering versatile installation options for fixed systems. With a maximum inlet pressure rating of 3500 PSIG and a 1/4" MNPT outlet, this regulator is a robust solution for controlling industrial air supplies.
