Delavan 00650-90a7 Oil Burner Nozzle 6.50 Gph 90 Degree

Product Description

The DELAVAN 00650-90a7 is a Type A hollow-cone oil burner nozzle rated at 6.50 GPH flow rate with a 90-degree spray angle. It is designed for residential oil-fired burner applications where a hollow cone air pattern is required. The brass body and steel orifice disc construction provide durability under normal service conditions. A sintered filter element is integrated into the nozzle assembly. Rated at 100 psi operating pressure and a temperature rating of 80 degrees F, this nozzle delivers concentrated droplet distribution along the outside of the spray cone, supporting reliable ignition and low-noise combustion.

This nozzle is suited for residential oil-fired heating systems where throughput requirements are at or below 2.00 GPH per the hollow cone Type A design specification, though this unit is rated at 6.50 GPH for applications demanding higher output. It is used in burners configured with a hollow cone air pattern. The hollow cone spray profile concentrates fuel droplets at the outer edge of the cone, making it appropriate for burner heads engineered to match that distribution pattern. Licensed oil burner technicians and HVAC service professionals are the primary installers.

Key Features

• Hollow cone Type A spray pattern concentrates droplets on the outside of the cone for consistent ignition
• 6.50 GPH flow rate at 100 psi rated operating pressure
• 90-degree spray angle for compatible burner head geometry
• Brass body with steel orifice disc for reliable service life
• Integrated sintered filter element to protect the orifice from debris
• ISO 9001 applicable standard manufacturing

Compatibility

Designed as an OEM-style replacement nozzle for residential oil-fired burner systems requiring a Type A hollow cone spray pattern at a 90-degree angle and 6.50 GPH flow rate.

Installation Notes

Oil burner nozzle replacement should be performed by a licensed oil burner technician or qualified HVAC service professional. Shut down the burner and disconnect power before servicing the nozzle assembly. Use the correct nozzle wrench to avoid damaging the brass body or misaligning the orifice disc. After installation, verify burner operation and combustion performance with appropriate test instruments before returning the system to service.
