Delavan 2.50-70-b 2.50 Gph 70 Degree Type B Solid Cone Oil Burner Nozzle

Product Description

The Delavan 2.50-70-b is a Type B Solid Cone oil burner nozzle designed for residential heating applications. It delivers a flow rate of 2.50 GPH at a spray angle of 70 degrees. HVAC technicians and heating contractors rely on this nozzle for dependable performance in oil-fired furnaces, boilers, and residential heating systems. The Solid Cone spray pattern distributes fuel droplets fairly uniformly throughout the complete spray pattern. This uniform distribution supports smooth ignition and promotes efficient combustion, which is especially important in larger residential burners. At flow rates above 8.00 GPH the spray pattern becomes progressively more hollow, but at 2.50 GPH this nozzle maintains consistent cone coverage for reliable burner operation. The nozzle body is constructed from brass, which resists corrosion and holds up well in demanding fuel oil environments. The orifice disc is made from steel, providing durability at the critical metering point where fuel atomization occurs. A Monel strainer is integrated into the nozzle to filter out contaminants before they reach the orifice, protecting the precision orifice from clogging and extending service life. The pressure rating of 100 PSI and temperature rating of 80 degrees F make it compatible with standard residential oil burner operating conditions. The 70 degree spray angle is a widely used angle in residential oil heating equipment, making this nozzle a common replacement part for routine maintenance and burner service calls. Manufactured to ISO 9001 standards, the Delavan 2.50-70-b meets established quality benchmarks expected by professional HVAC technicians. This nozzle is a direct replacement option for residential oil burner service, tune-ups, and combustion efficiency upgrades.

• Type B Solid Cone spray pattern for uniform droplet distribution throughout the full spray cone at residential flow rates
• Brass body and steel orifice disc construction for corrosion resistance and long service life in fuel oil environments
• Integrated Monel strainer filters contaminants to protect the precision orifice and maintain consistent atomization
