Delavan 0.50-80-A Del-o-flo Oil Burner Nozzle 0.50 Gph 80 Degree Type a Hollow Cone Red Vial

Product Description

The Delavan 0.50-80-A Del-O-Flo is a precision oil burner nozzle designed for residential and light commercial heating systems that run on fuel oil. This nozzle delivers a flow rate of 0.50 gallons per hour at a rated operating pressure of 100 PSI. It produces a hollow cone spray pattern at an 80-degree spray angle, which is classified as Type A. HVAC technicians and heating system service professionals rely on this style of nozzle for consistent, efficient fuel atomization in oil-fired furnaces, boilers, and water heaters. Proper atomization is critical to clean combustion. When fuel oil is broken into a fine mist at the correct angle and flow rate, the burner runs more efficiently, produces less soot, and reduces the risk of combustion problems. The hollow cone pattern distributes fuel around the outer edge of the spray cone, making it well suited for specific burner head configurations that require this spray geometry. The body of this nozzle is constructed from brass, which resists corrosion and holds up well in the demanding environment inside an oil burner assembly. The orifice disc is made from stainless steel, providing long-term durability and resistance to wear at the critical metering point. A red vial color coding system makes it easy to identify the correct nozzle during installation or service. HVAC technicians frequently stock multiple nozzle sizes and angles, and the color-coded vial helps prevent mix-ups in the field. This nozzle is a direct replacement part used during annual burner tune-ups, combustion analysis servicing, or any time a worn or clogged nozzle needs to be swapped out. Matching the correct GPH rating, spray angle, and pattern type to the burner manufacturer specifications is essential for safe and efficient operation.
