Fluidics W2-130-50 nozzle

The Fluidics W2-130-50 nozzle (catalogue article 480.892.089) is an oil nozzle listed in the oil nozzles category. Parts of this type are precision consumables that atomise the fuel oil into a fine spray cone, enabling complete combustion in the burner. In an oil-fired burner system, the nozzle works together with the oil pump, solenoid valve, and, where fitted, a preheater. The pump delivers oil at a regulated pressure to the nozzle, which then meters and atomises it. When selecting a replacement nozzle of this class, three parameters must be matched to the burner data plate: the flow rate (given in USGPH or kg/h at the reference pressure), the spray angle (typically between 30° and 80°), and the spray pattern (hollow cone, solid cone, or semi-solid). The thread size must also correspond to the burner’s nozzle holder. Using the correct flow rate but the wrong pattern can cause sooting, pulsation, or unstable ignition, so all three values must be verified. Because the nozzle is a wear item that degrades over time due to thermal stress and fuel residues, replacing it at the interval recommended by the burner manufacturer is essential for reliable operation and consistent flame shape.
