Fluidics W1-180-50 nozzle

The Fluidics W1-180-50 nozzle is an oil nozzle, a precision consumable part that atomises fuel oil into a fine spray cone for complete combustion. In an oil burner, this nozzle sits at the combustion head and works with the oil pump and solenoid valve to deliver fuel at the correct pressure and pattern. The spray cone must match the combustion head geometry to establish a stable flame that sits correctly in the blast tube. Parts of this type are selected by three key parameters: flow rate (given in USGPH or kg/h at a reference pressure), spray angle (typically 30° to 80°), and spray pattern (hollow, solid, or semi-solid). Thread size and type also vary among nozzles. Using a nozzle of the correct rating but wrong pattern can cause sooting, pulsation, or unreliable ignition. When replacing such a nozzle, always confirm the rating, angle, and pattern from the burner data plate. The nozzle output is rated at a specific pressure (usually 7 bar or 100 psi for domestic oil burners); if the working pressure differs, effective flow changes. Because the nozzle is a calibrated component, no attempt should be made to alter its orifice or spray angle. The W1-180-50 article is one variant within this product group; the designation indicates its family, but the correct selection must always be based on the burner manufacturer’s specification, not the code alone.
