Delavan 0.50-45-b 0.50 Gph 45 Degree Type B Solid Cone Oil Burner Nozzle

Product Description

The Delavan 0.50-45-b is a Type B Solid Cone oil burner nozzle built for residential heating systems that demand reliable ignition and consistent combustion. Designed and manufactured to ISO 9001 standards, this nozzle features a brass body paired with a steel orifice disc, giving it the durability and precision that HVAC technicians and oil burner service professionals rely on in the field. The nozzle delivers a flow rate of 0.50 GPH at a pressure rating of 100 PSI and is rated for operation at 80 degrees Fahrenheit, making it well suited for standard residential oil-fired heating applications. The 45 degree spray angle is one of the most common configurations used in residential boilers and furnaces, helping direct the fuel spray into the combustion chamber for efficient burn performance. The Type B Solid Cone spray pattern distributes droplets fairly uniformly throughout the complete cone pattern. This uniform distribution supports smooth ignition and efficient combustion, especially in larger residential burners where an even fuel-air mixture is critical. It is worth noting that the spray pattern can become progressively more hollow at higher flow rates, particularly above 8.00 GPH, but at 0.50 GPH this nozzle operates well within the ideal range for a consistent solid cone pattern. The sintered filter screen integrated into the nozzle body helps protect the orifice disc from debris that could disrupt spray pattern or reduce flow accuracy. HVAC technicians replacing worn or clogged nozzles on oil burners will find this a direct and dependable solution for residential service calls. Whether you are performing seasonal maintenance, troubleshooting combustion issues, or completing a full burner tune-up, the Delavan 0.50-45-b delivers the precision and repeatability that keeps heating systems running efficiently all season long.
