The DELAVAN .60 70 W is a semi-solid, Type W oil burner nozzle rated at 0.60 gallons per hour (GPH) with a 70-degree spray angle. Constructed from brass, it atomizes fuel oil into a fine, consistent pattern for efficient combustion in residential and light commercial oil-fired heating equipment. The semi-solid spray pattern delivers a blend of hollow and solid cone characteristics, making it a versatile all-purpose choice. Licensed oil burner technicians and HVAC service professionals install this nozzle as a routine maintenance replacement during annual tune-ups or burner servicing.
This nozzle is suited for residential oil-fired furnaces, boilers, and water heaters operating at standard firing rates that require a 0.60 GPH flow rate and a 70-degree spray angle. The Type W semi-solid pattern is commonly specified for a wide range of burner heads where an all-purpose atomization profile is acceptable. It is a direct drop-in replacement during routine service calls on oil heating systems of comparable firing capacity.
Designed as an OEM-style replacement nozzle for residential and light commercial oil-fired furnaces, boilers, and water heaters requiring a 0.60 GPH, 70-degree, Type W semi-solid spray pattern.
Oil burner nozzles should be replaced by a licensed oil burner technician or qualified HVAC service professional. Shut down the burner and allow the system to cool before servicing. Use a proper nozzle wrench to avoid damaging the nozzle adapter, and always replace the nozzle with the exact GPH rating, spray angle, and pattern type specified for the burner. Refer to the burner manufacturer service manual and applicable local codes for fuel oil system servicing requirements.
