Resideo 388468D LP Gas Orifice L10

The Resideo 388468D LP Gas Orifice L10 is an accurate fuel metering part that is applied in HVAC systems to control the flow of liquid propane. Its main purpose is to regulate the amount of the gas fed to the burner by creating a precise opening in the line. The concept of operation is that gas is forced through the specified size of the orifice to provide adequate pressure and combustion properties. It involves sitting the orifice at the fitting of the gas valve that fits the direction of the flow.
