Delavan 0.70-80-a 0.70 Gph 80 Degree a Hollow Cone Oil Burner Nozzle

Product Description

The Delavan 0.70-80-a is a precision-engineered oil burner nozzle designed for residential heating applications. It delivers a flow rate of 0.70 gallons per hour at a spray angle of 80 degrees using a Type A hollow cone spray pattern. HVAC technicians and heating system service professionals rely on this nozzle for consistent, clean fuel atomization in oil-fired boilers and furnaces. Proper fuel atomization is critical to combustion efficiency. A well-matched nozzle ensures the right fuel-to-air ratio, reduces soot buildup, and extends the life of the heat exchanger and combustion chamber. The Delavan 0.70-80-a is built to meet these demands with a brass body and steel orifice disc for durability and long service life. The brass body resists corrosion from heating oil and holds up through repeated heat cycles. The steel orifice disc maintains a precise spray pattern over time, which keeps combustion consistent season after season. This nozzle includes a sintered filter that traps fine particles before they reach the orifice. Keeping the orifice clear is essential for maintaining the rated flow and spray pattern. A clogged or worn nozzle can cause hard starts, smoke, and inefficient fuel burn. Replacing the nozzle with a correctly rated unit like the 0.70-80-a restores proper burner performance quickly. The 0.70 GPH flow rate is common in smaller residential oil burners, making this a frequently requested replacement part during annual tune-ups and service calls. The 80-degree spray angle pairs well with standard flame retention burner heads used in many residential systems. ISO 9001 manufacturing standards apply, supporting dimensional consistency and quality control across production runs. HVAC techs can install this nozzle with confidence knowing the specs are reliable and repeatable.
