Delavan Oil nozzle P0080-60W1

The Delavan Oil nozzle P0080-60W1 is a precision consumable component for pressure-jet oil burners. It has a flow rate of 0.8 GPH (gallons per hour) and a spray angle of 60 degrees. The spray pattern is designated as W, with pattern variant 1. This nozzle is identified by manufacturer code P0080-60W1 and article number 345.892.077. It is installed in the burner's blast tube and should be replaced at regular service intervals.

When selecting a replacement oil nozzle of this type, the flow rate, spray angle, and spray pattern must match the burner data plate. The spray angle typically ranges between 30° and 80°, and the pattern can be hollow, solid, or semi-solid, as coded in the manufacturer's designation. The thread size is also a selection criterion, though it may not be stated in available data. The nozzle is mounted in the burner's blast tube and receives fuel from the oil pump via the solenoid valve and, where fitted, a preheater.

A worn or incorrect oil nozzle can cause sooting, pulsation, or unstable ignition. If the flow rate is correct but the pattern is wrong, combustion may be incomplete, leading to poor flame detection by UV or IR sensors. Regular replacement at intervals prescribed by the burner service manual is necessary to avoid these issues.
