122-2009 - Miller Smith Silverline 2-Stage Inert Gas Regulator, 0-100 PSI, CGA 580

Precision Control for Inert Gas Applications

The Miller Smith 122-20-09 Silverline Series General Purpose Two Stage Regulator is engineered to provide reliable and precise pressure control for inert and non-corrosive gases such as Air, Nitrogen, Helium, and Argon. Designed for laboratory, general plant, and maintenance shop environments, this regulator excels in applications where a constant delivery pressure is critical. The two-stage reduction mechanism compensates for the drop in cylinder pressure as the gas is consumed, ensuring a stable output without the need for frequent manual readjustments. This feature is particularly valuable in long-duration processes where consistency is key.

Constructed from rugged brass bar stock, the body and bonnet are plated to offer superior protection against corrosion and wear. The regulator features a large 1-7/8 inch diaphragm which provides exceptional sensitivity and precise control over the 0-100 PSIG delivery range. A filtered seat is integrated into the design to trap particulates, enhancing the purity of the gas stream and significantly extending the service life of the seat assembly. The unit is equipped with large, 2-1/2 inch single-scale gauges that are easy to read, allowing operators to monitor cylinder and delivery pressure at a glance.

Safety and versatility are built into the 122-20-09. It includes a preset safety relief valve that vents to the atmosphere, making it suitable for non-hazardous gas applications. The body is also tapped for rear panel mounting, offering flexible installation options for fixed systems. With a maximum inlet pressure rating of 3500 PSIG and a CGA 580 connection, this regulator is a robust solution for managing high-pressure inert gas cylinders. Note that while the series covers various gases, the CGA 580 fitting specifically connects to standard inert gas cylinders.
