Delavan 4.50-60-b 4.5 Gph 60 Degree Type B Solid Cone Oil Burner Nozzle

Product Description

The Delavan 4.50-60-b is a Type B Solid Cone oil burner nozzle designed for residential heating systems. It delivers a flow rate of 4.5 gallons per hour at a spray angle of 60 degrees. HVAC technicians and oil burner service professionals rely on this nozzle for clean, consistent fuel atomization in forced-air furnaces and boiler systems. The solid cone spray pattern distributes droplets uniformly throughout the full spray cone. This makes it well suited for larger residential burners where smooth ignition and stable combustion are critical. At flow rates above 8.00 gallons per hour, the pattern becomes progressively more hollow, but at 4.5 gallons per hour this nozzle maintains an even, reliable distribution. The brass body provides corrosion resistance and durability in heating oil environments. The steel orifice disc delivers consistent spray geometry over repeated firing cycles. A built-in Monel strainer filters out particulates that could clog the orifice or disrupt the spray pattern. This nozzle is rated for operation at 100 PSI and a temperature rating of 80 degrees Fahrenheit, making it appropriate for standard residential oil burner applications. It meets ISO 9001 standards, confirming consistent manufacturing quality. Whether you are performing a seasonal tune-up, replacing a worn nozzle, or commissioning a new oil-fired heating system, the Delavan 4.50-60-b is a direct fit for systems that call for a 4.5 GPH, 60-degree, Type B nozzle. Proper nozzle selection is one of the most important steps in achieving efficient combustion and reducing soot buildup in heat exchangers and flue passages.

• Type B Solid Cone spray pattern for uniform droplet distribution across the full cone at 4.5 GPH
• Brass body and steel orifice disc construction for durability in residential oil burner service
• Built-in Monel strainer protects the orifice from particulates for consistent spray performance
