Norgas Controls and Metering NGR02-DDA Gas Regulator 1-1/4" NPT 1/2" Orifice 6.5"-16" WC

The Norgas Controls and Metering NGR02-DDA Gas Regulator is a gas pressure regulation component used to maintain consistent downstream fuel pressure for burner and heating applications. It is installed in gas supply lines, where it reduces incoming pressure and stabilizes flow to ensure proper combustion performance. The 1-1/4" NPT 1/2" Orifice 6.5"-16" WC specification defines the inlet connection size, flow orifice and regulated pressure range, allowing accurate fuel delivery under supply conditions. In HVAC systems, it supports secure and efficient operation of gas-fired equipment by maintaining steady fuel delivery, improving burner stability, combustion efficiency, and overall system during operation.
