Description
The Norgas Controls and Metering B42R-1 is a 1-inch Internal Relief Valve (IRV) engineered for precision gas pressure management in commercial and industrial metering applications. Featuring a 1/2 x 9/16-inch orifice and a dark green color-coded spring calibrated for a 6 to 16 inches water column (W.C.) pressure range, this IRV provides dependable overpressure protection within gas distribution and metering systems.
Designed to integrate seamlessly into Norgas metering assemblies, the B42R-1 helps safeguard downstream equipment by relieving excess pressure before it reaches critical thresholds. The color-coded dark green spring allows for quick field identification of the correct pressure range, reducing installation errors and simplifying maintenance.
