Delavan Oil nozzle 00200-80W1

The Delavan Oil nozzle 00200-80W1 is a precision consumable component that atomizes fuel into a fine spray for complete combustion in an oil burner. It has a capacity of 2 gallons per hour (GPH) and a spray angle of 80 degrees. The spray pattern is type W, which is neither truly hollow nor solid and can frequently be used in place of either solid or hollow cone nozzles. This nozzle is identified by the manufacturer code 00200-80W1 and is compatible with flow rates ranging from 0.40 to 8.00 GPH. It is installed in the oil supply line between the pump and the combustion head, working together with the oil pump, solenoid valve, and preheater if fitted.

When selecting a replacement nozzle of this type, three interdependent parameters must match the burner manufacturer's data plate: flow rate at a reference pressure, spray angle, and spray pattern. Using the correct flow rate but the wrong pattern can lead to sooting, flame pulsation, or unreliable ignition. Parts of this type are installed in the oil supply line between the pump and the combustion head. Always verify the flow rate, angle, and pattern against the burner manual before ordering.

Nozzles of this kind are wear items that lose their precise spray geometry over time due to heat and fuel deposits. This can result in incomplete combustion, sooting, flame pulsation, or unreliable ignition. Routine replacement is part of standard burner maintenance to ensure correct flame shape and stable operation.
