Delavan 00650-90B7 Oil Burner Nozzle 6.50 Gph 90 Degree

Product Description

The DELAVAN 00650-90B7 is a solid-cone Type B oil burner nozzle rated at 6.50 gallons per hour (GPH) with a 90-degree spray angle. It is designed to atomize fuel oil into a fine, uniform spray pattern that supports smooth ignition and efficient combustion in residential oil-fired heating systems. The brass body and steel orifice disc construction provide reliable service at a rated pressure of 100 psi. The integrated sintered filter helps protect the orifice from debris. Licensed oil burner technicians install this nozzle as a routine maintenance or service replacement component.

This nozzle is suited for residential oil burner applications where a solid-cone spray pattern is specified. Solid-cone Type B nozzles distribute droplets fairly uniformly throughout the complete spray pattern at moderate flow rates. The spray pattern becomes progressively more hollow at higher flow rates, particularly above 8.00 GPH. This makes the 00650-90B7 well matched to larger residential burners that benefit from the more uniform distribution a solid-cone pattern provides at the 6.50 GPH flow rate.

Key Features

• Solid-cone Type B spray pattern for uniform droplet distribution at rated flow
• 6.50 GPH flow rate at 100 psi operating pressure
• 90-degree spray angle for compatible burner head geometry
• Brass body with steel orifice disc for durability
• Integrated sintered filter to protect the orifice from particulate contamination
• Manufactured to ISO 9001 quality standards

Compatibility

Designed as a standard replacement oil burner nozzle for residential oil-fired heating equipment specifying a solid-cone Type B nozzle at 6.50 GPH and a 90-degree spray angle.

Installation Notes

Oil burner nozzle replacement is performed 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 remove and install the nozzle to avoid damaging the nozzle adapter or electrodes. Always verify the replacement nozzle GPH rating, spray angle, and spray pattern type match the burner manufacturer specifications before firing the unit.
