Featuring a 3/4″ pipe connection and a 1/4″ orifice, this valve is color-coded green to indicate its 6–14″ W.C. (water column) pressure operating range, making identification fast and reliable in the field.
Key Features
- 3/4″ pipe connection for straightforward installation into standard gas lines
- 1/4″ orifice sized for precise flow and pressure relief performance
- Green color coding for quick visual identification of the 6–14″ W.C. pressure range
- Operating pressure range: 6–14″ W.C. (water column)
- Internal relief valve design protects downstream equipment from over-pressure conditions
- Built to Sensus Gas Division quality standards for dependable, long-service performance
Application
This IRV is well-suited for use in gas pressure regulating stations, meter sets, and distribution systems where maintaining safe downstream pressure is critical. The internal relief function vents excess pressure internally, helping to protect connected appliances and piping from potentially damaging over-pressure events.
