Description
Overview
The Sensus 121-8-2 is a 2-inch gas pressure regulator engineered for dependable downstream pressure regulation in commercial and industrial gas distribution systems. Equipped with a black spring calibrated for an outlet pressure range of 2 to 4.25 pounds per square inch (PSI), this regulator is designed to maintain consistent gas pressure under varying flow conditions, helping to protect downstream equipment and ensure safe, efficient operation.
Key Features
- 2-inch (2″) regulator body for high-capacity gas flow applications
- Black spring with an outlet pressure range of 2–4.25 PSI
- Designed for use in commercial and industrial gas distribution systems

Application
The Sensus 121-8-2 regulator is well-suited for natural gas and LP gas service applications where precise pressure control is required. The 2-inch connection size makes it appropriate for medium- to large-scale distribution lines, and the 2–4.25 PSI black spring range is ideal for systems requiring low-pressure outlet settings downstream of high-pressure supply lines.
