The Norgas Controls and Metering NGR02-BBA 3/4" Gas Regulator 1/4" Orifice 6.5 -16" WC is a control element that is required in HVAC systems to stabilize and regulate the pressure of gas that is supplied to heating parts. This system works by limiting the pressure inlet to a regulated outlet to maintain steady combustion throughout the operation. It is used in commercial and residential furnaces, boilers, and unit heaters and plays a major role in the system concept in that it controls the fuel delivery, pressure balance, and damage due to change of pressure under normal operating conditions.
