Delavan 0.90-70-A Oil Burner Nozzle 0.9 Gph 70 Degree

Product Description

The DELAVAN 0.90-70-A is a hollow-cone oil burner nozzle rated at 0.9 gallons per hour (GPH) with a 70-degree spray angle and a 100 psi operating pressure. It is identified by a red vial for quick field identification. This Type A nozzle is engineered for oil-fired burner assemblies where the air pattern matches a hollow-cone spray profile. Droplet distribution concentrates on the outer edge of the cone, supporting reliable ignition and low-noise combustion. HVAC technicians and oil burner service professionals install this nozzle as part of routine maintenance or burner setup on residential and light commercial heating equipment.

The 0.90-70-A is suited for oil burner applications with throughput requirements up to 2.00 GPH. The 70-degree spray angle and hollow-cone pattern work in conjunction with burners designed around a hollow-cone air pattern. It is a standard replacement nozzle used during annual tune-ups, combustion efficiency service calls, and burner conversions where matching the correct spray angle and flow rate is critical to achieving proper flame shape and combustion performance.

Key Features

• Hollow-cone Type A spray pattern concentrates droplets on the outside of the cone for stable ignition
• 0.9 GPH flow rate supports throughput applications up to 2.00 GPH
• 70-degree spray angle matched to burners with a hollow-cone air pattern
• 100 psi rated operating pressure
• Red vial color coding allows fast nozzle identification in the field
• Designed to deliver low-noise combustion characteristics

Compatibility

Designed as an OEM-style replacement nozzle for oil-fired burners requiring a hollow-cone Type A nozzle with a 0.9 GPH flow rate and 70-degree spray angle.

Installation Notes

Oil burner nozzle replacement is performed by qualified oil heat technicians following applicable NFPA 31 guidelines. Shut down the burner and allow all components to cool before beginning service. Use a proper nozzle wrench to avoid damage to the nozzle adapter or electrode assembly. Always verify the replacement nozzle matches the original spray angle, flow rate, and cone type specified on the burner nameplate before firing.
