Description
Norgas Controls and Metering N5A Series Gas Pressure Regulator
The Norgas Controls and Metering N5A-0500-S-VL0125 is a dependable gas pressure regulator engineered for precise downstream pressure control in commercial and residential gas distribution systems. Featuring a 1/2″ NPT connection and a factory-set outlet pressure range of 7–11″ W.C. (water column), this regulator is well-suited for natural gas appliance supply lines, HVAC equipment, and other gas-fired systems requiring consistent, regulated pressure delivery.
The integrated vent limiter (VL) is a key safety feature that restricts the flow of gas from the regulator vent in the event of a diaphragm failure, helping to reduce the risk of hazardous gas accumulation in confined or indoor installations. This makes the N5A-0500-S-VL0125 an ideal choice for applications where venting to atmosphere indoors is required and code compliance demands a vent limiting device.
