Delavan Oil nozzles 00900-45B7

The Delavan 9.00GPH, 45B oil nozzle (SKU 00900-45B7, type P0135-45W1) is a component for oil burners, designed to regulate fuel flow and atomize oil for combustion. It has a capacity of 9 gallons per hour (9 GPH) and a spray angle of 45 degrees with a B spray pattern. This nozzle contributes to energy saving and efficient, stable, and safe combustion, while reducing emissions of harmful substances. It is installed in burners for heating systems and boilers.

Oil nozzles of this type are selected by matching the flow rate (GPH), spray angle, and spray pattern to the burner's specifications. Before ordering, verify the nozzle's capacity and angle against the burner manual or existing nozzle markings. Installation involves removing the old nozzle and fitting the new one securely, ensuring proper alignment and torque.

When oil nozzles fail, common symptoms include poor combustion, soot buildup, or unstable flame. The burner may struggle to ignite, produce excessive smoke, or have reduced heating efficiency. Check the nozzle for clogging, wear, or damage, and replace it if necessary.
