Delavan 1.20-70-b Oil Burner Nozzle 1.20 Gph 70 Degree Solid Cone Type B

Product Description

The Delavan 1.20-70-B is a solid cone Type B oil burner nozzle designed for residential heating systems that run on fuel oil. It delivers a steady, controlled spray of fuel into the combustion chamber of an oil-fired furnace, boiler, or water heater. HVAC technicians and heating system installers rely on Delavan nozzles for consistent atomization and repeatable performance across a wide range of oil burner applications. This nozzle produces a flow rate of 1.20 gallons per hour at a standard operating pressure of 100 PSI, making it suitable for low-to-mid capacity residential heating equipment. The 70-degree spray angle produces a wide, solid cone pattern that promotes thorough fuel-air mixing and efficient combustion. A solid cone pattern means fuel is distributed evenly throughout the entire cone shape, not just along the outer edge. This helps reduce unburned fuel, lower smoke output, and improve combustion efficiency. The nozzle body is constructed from brass, which resists corrosion and holds up well under the heat and pressure conditions found inside an oil burner assembly. The orifice disc is made from steel for durability and precise spray geometry. A sintered filter is integrated into the nozzle to trap debris before it reaches the orifice, helping to protect the spray pattern and extend service life. This nozzle meets ISO 9001 quality standards, which means it is manufactured under a documented quality management system. It is rated for use at temperatures up to 80 degrees Fahrenheit on the inlet side and operates reliably at 100 PSI. HVAC service professionals should match the nozzle flow rate and angle to the specific burner manufacturer specifications before installation. The Delavan 1.20-70-B is a direct replacement nozzle for residential oil heating systems requiring a 1.20 GPH, 70-degree, solid cone Type B nozzle.

• Solid cone Type B spray pattern ensures even fuel distribution and efficient combustion in residential oil burners
• Brass body and steel orifice disc construction provide durability and corrosion resistance under normal operating conditions
• Integrated sintered filter helps protect the orifice from debris and maintains consistent spray performance
