Ugello Delavan 0.90GPH, 60B (1)

This Delavan oil nozzle is a precision component that atomises fuel oil into a fine spray cone for complete combustion. It is a consumable part designed for a specific flow rate, spray angle, and pattern. The nozzle is identified by its manufacturer code P0090-60B1 and catalogue article 345.892.098, with a rated flow of 0.90 GPH. The designation 60B indicates the spray angle and pattern type, but these markings are part of the manufacturer's coding system and should be verified against the burner data plate. In an oil-fired burner system, the nozzle is mounted in the combustion head and receives pressurised oil from the pump via the solenoid valve. The atomised oil mixes with combustion air delivered by the fan. For a replacement to work correctly, the flow rate (GPH), spray angle, and pattern (hollow, solid, or semi-solid) must all match the burner’s original specification. Using a nozzle with the correct flow but wrong pattern can cause sooting, flame instability, or ignition failure. This part operates at the reference pressure stated on the burner nameplate; no additional dimensions or thread details are provided here, so the installer should confirm that the physical fit is appropriate for the existing burner head.
