Delavan 0.65GPH, 60W (1) nozzle

This is a Delavan oil nozzle, listed as 0.65 GPH, 60W (1). The catalogue article is 345.892.019; the manufacturer code is P0065-60W1. It belongs to the category of oil nozzles. An oil nozzle of this type atomises fuel oil into a fine spray cone so that it can be fully burned in the combustion head. It is a precision consumable part: the flow rate (in GPH or kg/h at the reference pressure), spray angle, and spray pattern together determine how the flame sits in the burner. Selection must match all three parameters to the burner data plate – a nozzle with the correct rating but wrong pattern can cause sooting, pulsation, or unstable ignition. The part is replaced as a unit; no adjustment is possible. For this specific article, the rated flow is 0.65 GPH at the standard reference pressure, as indicated in the product name. The "60W" designation refers to the spray angle and pattern (commonly 60 degrees wide, though this should be confirmed against the burner specification). When replacing, ensure the flow, angle, and pattern exactly match the original nozzle fitted. Always check the burner manual or data plate for the correct nozzle code before ordering.
