Delavan Oil nozzle PH030-60B4

The Delavan Oil nozzle PH030-60B4 is a low-flow oil nozzle with a capacity of 0.3 gallons per hour and a spray angle of 60 degrees. It features a spray pattern classified as 'W', indicating it is neither truly hollow nor solid. This nozzle is designed to minimize clogging at very low flow rates by using a special interior design that flushes contaminants through, reducing build-up. It is compatible with other hollow and solid cone nozzles in the range of 0.40 to 8.00 gph, with lower flow rates tending to be more hollow. The nozzle's low contamination sensitivity and minimized clogging risk make it suitable for applications requiring precise low-flow oil delivery.

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 flow rate and angle must correspond to the manufacturer's specifications for the burner. Installation involves removing the old nozzle and fitting the new one securely, ensuring proper alignment and torque. Always verify the nozzle's compatibility with the burner's air pattern and flow range before installation.

Oil nozzles of this kind can fail due to clogging from contaminants, leading to improper atomization and incomplete combustion. Symptoms include soot buildup, reduced heating efficiency, or a noisy flame. Regular inspection and cleaning of the nozzle and its filter can prevent such issues. If the nozzle is blocked, the burner may fail to ignite or produce a weak, uneven flame.
