Delavan 4.00-60-b 4.00 Gph 60 Degree B Solid Cone Oil Burner Nozzle

Product Description

The Delavan 4.00-60-b is a solid cone oil burner nozzle rated at 4.00 gallons per hour with a 60 degree spray angle. It is built for domestic and commercial high pressure oil burner systems that run on light or heavy fuel oil. HVAC technicians and oil burner service professionals rely on nozzles like this one to keep heating systems running cleanly and efficiently. The nozzle controls the flow rate, spray angle, and pattern of fuel entering the combustion chamber. Getting these three factors right is critical to achieving complete combustion and maximum heat output with minimal waste. The 4.00-60-b uses a solid cone spray pattern, which is designated by the letter B. This pattern delivers a consistent and even distribution of fuel droplets across the full face of the flame. The 60 degree angle suits a wide range of residential and light commercial oil burner applications, directing the fuel spray into the combustion zone with the proper geometry to match standard firebox dimensions. High pressure oil burner nozzles operate by forcing fuel oil through a precision-machined tip and disc at pressures typically between 100 and 200 PSI. This atomizes the oil into a fine mist that mixes with air and ignites reliably. The nozzle tip and disc on the 4.00-60-b are machined from AISI 416 grade stainless steel, a material chosen for its corrosion resistance and dimensional stability under repeated thermal cycling. The internal filter screens out debris that could clog the precision orifice, with filter size matched to the nozzle capacity. Replacing the nozzle at each annual service call is standard practice in the oil heating industry. Using the correct flow rate and spray pattern prevents soot buildup, excessive smoke, and inefficient fuel consumption. The 4.00-60-b is a direct fit for burners requiring a 4.00 GPH solid cone nozzle at 60 degrees.
