Delavan 2.50-80-b 2.50 Gph 80 Degree Solid Cone Type B Oil Burner Nozzle

Product Description

The Delavan 2.50-80-b is a Solid Cone Type B oil burner nozzle designed for residential heating systems. It delivers a flow rate of 2.5 GPH at a spray angle of 80 degrees. This nozzle is a go-to choice for HVAC technicians and heating equipment service professionals who need reliable, repeatable combustion performance in oil-fired furnaces and boilers.

Type B Solid Cone nozzles distribute droplets evenly throughout the entire spray pattern. This uniform distribution supports smooth ignition and efficient combustion, especially in larger residential burners. The spray pattern remains consistent at lower flow rates and becomes progressively more hollow above 8.0 GPH. At 2.5 GPH, this nozzle operates well within the optimal solid-cone range, making it a dependable choice for standard residential oil burner applications.

The nozzle body is constructed from brass, which resists corrosion and holds up well in fuel oil environments. The orifice disc is made from steel for durability and consistent spray performance over time. A Monel strainer filters incoming fuel to protect the orifice from debris and contamination. Monel is a nickel-copper alloy known for its resistance to fuel oil, water, and oxidation. This strainer helps extend the service life of the nozzle and reduces the risk of clogging or erratic spray patterns.

This nozzle meets ISO 9001 quality standards, confirming that it is manufactured under a certified quality management system. It is rated for operation at 100 PSI and 80 degrees Fahrenheit. HVAC technicians installing or replacing oil burner nozzles in residential furnaces, boilers, or water heaters will find this nozzle compatible with standard Delavan nozzle body threads. It is a direct replacement option for systems requiring a 2.5 GPH, 80-degree, Type B solid cone nozzle.

• Solid Cone Type B spray pattern for uniform droplet distribution and smooth ignition
• Brass body and steel orifice disc for corrosion resistance and long service life
• Monel strainer filters fuel to protect the orifice and maintain consistent spray performance
