Delavan 2.00GPH, 80W (1) nozzle

This Delavan oil nozzle is a precision consumable component that atomises fuel into a fine spray for complete combustion in an oil burner. The article is identified as a 2.00 GPH unit with the manufacturer code 00200-80W1 and the catalogue reference 345.892.087. The flow rating of 2.00 GPH is stated on the product name, but the designation 80W should not be interpreted here; instead, it indicates that such nozzles are selected by three interdependent parameters: flow rate at a reference pressure, spray angle, and spray pattern. When replacing a nozzle, all three must match the burner manufacturer’s data plate. Using the correct flow rate but the wrong pattern can lead to sooting, flame pulsation, or unreliable ignition, so the exact specification is critical. Parts of this type are installed in the oil supply line between the pump and the combustion head. They work together with the oil pump, solenoid valve, and preheater (if fitted). The nozzle is a wear item that loses its precise spray geometry over time due to heat and fuel deposits; routine replacement is part of standard burner maintenance. To ensure correct flame shape and stable operation, always verify the flow rate, angle, and pattern against the burner manual. This article is a Delavan-branded nozzle with a given GPH rating; the other parameters (angle and pattern) are embedded in the code and must be confirmed from the full manufacturer designation.
