Delavan Oil nozzle P0050-60E5

The Delavan Oil nozzle P0050-60E5 is a precision fuel-metering component for oil burners, rated at 0.5 gallons per hour (GPH) with a 60-degree spray angle and an E spray pattern. It atomizes pressurized liquid fuel into a fine spray cone for efficient combustion. This nozzle has a capacity of 0.5 kg/h and is identified by article number 345.892.139. It is designed for use in high-pressure oil burner systems.

When selecting a replacement oil nozzle of this type, verify the flow rate (in GPH at the reference pressure), spray angle, and spray pattern against the burner manufacturer's specification. The thread size is standardized, but confirm compatibility with the burner's nozzle adapter. Before installation, isolate the oil supply and set the pump pressure to the specified value. Inspect the nozzle seat for damage or debris, then fit the new unit and check for leaks.

Oil nozzles of this kind can fail due to clogging, wear, or damage, leading to improper atomization. Symptoms include sooting, pulsation, unstable ignition, or flame impingement on the combustion head or heat exchanger. Check the nozzle for debris or erosion and verify that the flow rate, angle, and pattern match the burner's requirements.
