Delavan Oil nozzles P0135-45W1

The Delavan P0135-45W1 is an oil nozzle with a capacity of 1.35 gallons per hour and a spray angle of 45 degrees. It features a W spray pattern, which is neither truly hollow nor solid, and can often replace solid or hollow cone nozzles. This nozzle is designed for use in burners to regulate fuel flow, atomize fuel for efficient combustion, and help prevent carbon monoxide formation. It is compatible with flow rates ranging from 0.40 to 8.00 gph.

When selecting a replacement oil nozzle of this type, ensure the capacity (in gallons per hour), spray angle, and spray pattern match the burner's requirements. The nozzle's thread size and type must also be compatible with the burner's adapter. Before installation, compare the nozzle's markings with the original part's specifications, and verify that the flow rate and angle are appropriate for the burner's application.

Oil nozzles of this kind can fail due to clogging from debris or carbon buildup, leading to incomplete combustion, soot formation, or uneven flame. Symptoms include reduced heating efficiency, increased fuel consumption, or the burner failing to ignite. Regular inspection and cleaning of the nozzle can prevent these issues.
