Delavan 00900-90B7 Oil Burner Nozzle 9 Gph 90 Degree

Product Description

The DELAVAN 00900-90B7 is a solid-cone Type B oil burner nozzle rated at 9.00 gallons per hour (GPH) with a 90-degree spray angle. It is designed for residential oil-fired heating systems where smooth ignition and efficient combustion are required. The nozzle features a brass body with a steel orifice disc and a sintered filter, operating at a rated pressure of 100 psi. The solid-cone spray pattern distributes droplets uniformly throughout the full pattern at standard flow rates. Note that the pattern becomes progressively more hollow at flow rates above 8.00 GPH. Licensed oil burner technicians and heating service professionals are the typical installers of this component.

This nozzle is suited for residential oil burner applications where a solid-cone spray pattern supports stable flame formation and complete combustion. Solid-cone Type B nozzles perform well in larger residential burner configurations where the uniform droplet distribution across the full cone angle contributes to consistent ignition. The 90-degree spray angle makes this nozzle appropriate for shorter combustion chambers typical of residential heating equipment. Always verify burner manufacturer specifications for nozzle type, flow rate, and spray angle before installation.

Key Features

• Solid-cone Type B spray pattern for uniform droplet distribution across the full cone at standard flow rates
• 9.00 GPH flow rate at 100 psi operating pressure
• 90-degree spray angle suited to shorter combustion chambers
• Brass body with steel orifice disc construction for durability in oil service
• Sintered filter type for particulate protection at the nozzle inlet
• Manufactured to ISO 9001 quality standards

Compatibility

Designed as an OEM-style replacement nozzle for residential oil-fired burner systems requiring a solid-cone Type B nozzle at 9.00 GPH and a 90-degree spray angle. Confirm burner nameplate and service manual specifications before replacing.

Installation Notes

Oil burner nozzle replacement should be performed by a licensed oil burner technician or qualified heating service professional. Before servicing, shut off fuel supply and disconnect electrical power to the burner. Use an appropriate nozzle wrench to avoid damaging the nozzle body or adapter; do not overtighten. Confirm that the replacement nozzle matches the required flow rate, spray angle, and pattern type listed on the burner nameplate or service documentation.
