Delavan 0.50-70-W Oil Burner Nozzle 0.5 Gph 70 Degree

Product Description

The DELAVAN 0.50-70-W is a Type W all-purpose oil burner nozzle rated at 0.5 gallons per hour (GPH) with a 70-degree spray angle and an operating pressure of 100 psi. Type W nozzles produce a spray pattern that is neither fully hollow nor fully solid cone, making them adaptable across a wide range of oil-fired appliance configurations. This nozzle is identified by a green vial and is designed for installation by HVAC technicians and oil-burner service professionals working on residential and light-commercial heating equipment.

The 0.50-70-W is suited for oil burner applications across the 0.4 to 8.00 GPH flow-rate range where a Type W spray pattern is called for. At lower flow rates, the spray pattern tends toward a more solid cone, which can be beneficial in burners where flame shape and combustion stability are critical. Its all-purpose nature means it can frequently substitute for either solid or hollow cone nozzles without requiring changes to the burner air-pattern setup, simplifying service calls where an exact-match nozzle is unavailable.

Key Features

• Type W all-purpose spray pattern — compatible with both solid and hollow cone burner configurations
• 0.5 GPH flow rate at 100 psi operating pressure
• 70-degree spray angle for wide-pattern combustion coverage
• Green vial color coding for fast field identification
• Lower flow rates produce a more solid spray pattern for improved flame stability
• Usable across the 0.4 to 8.00 GPH application range

Compatibility

Designed as an OEM-style replacement nozzle for residential and light-commercial oil-fired burners requiring a Type W all-purpose nozzle at 0.5 GPH and a 70-degree spray angle.

Installation Notes

Oil burner nozzle replacement is performed by qualified HVAC or oil-burner service technicians. Shut down the burner and allow the system to cool before beginning service. Use a proper nozzle wrench to remove and install the nozzle to avoid damage to the nozzle adapter or electrodes. After installation, verify combustion performance with appropriate test equipment before returning the system to service.
