122-4009 - Miller Smith Silverline 2-Stage Inert Gas Regulator 0-100 PSI CGA 580

Precise Inert Gas Control with Miller Smith Silverline

The Miller Smith 122-40-09 Silverline Series General Purpose Two Stage Regulator is engineered for applications requiring stable and precise delivery pressures. Designed for use with inert and non-corrosive gases such as Air, Nitrogen, CO2, and Argon, this regulator features a CGA 580 inlet connection compatible with standard industrial gas cylinders. The unit is constructed from rugged brass bar stock, ensuring structural integrity, while the plated body, bonnet, and gauges provide superior protection against corrosion and wear in industrial environments.

At the core of this regulator is a two-stage mechanism that reduces cylinder pressure in two steps, resulting in a constant delivery pressure regardless of fluctuations in the inlet pressure. This is particularly critical in laboratory and testing environments where consistent flow is mandatory as the supply cylinder empties. The regulator utilizes a large 1-7/8 inch diaphragm, which enhances sensitivity and allows for fine-tuned pressure adjustments within the 0-100 PSI delivery range. The inclusion of a filtered seat adds an extra layer of protection, preventing debris from entering the gas stream and extending the service life of the internal components.

Safety and usability are paramount in the 122-40-09 design. It includes a preset safety relief valve that vents to the atmosphere, making it suitable for non-hazardous gases. The large 2-1/2 inch single scale gauges are easy to read, allowing operators to monitor cylinder and delivery pressures at a glance. With a maximum inlet pressure rating of 3500 PSIG, this regulator is robust enough to handle high-pressure supply sources while delivering reliable performance for general plant, maintenance, and laboratory tasks.
