Description

The Delavan 1.50 GPH 80° Type B Solid Cone Fuel Nozzle (identified by its blue protective cap) is a professional-grade heating and combustion component. It serves as a critical replacement part for the burner assemblies of hot water pressure washers, commercial boilers, and oil furnaces, where it atomizes fuel to ensure highly efficient, clean, and stable heat generation.

With a 1.50 GPH flow rate, this nozzle provides a precise, medium-capacity thermal output, making it one of the most common configurations for standard industrial hot water pressure washers.

Key Features

• Type B Solid Cone Pattern: Distributes atomized fuel droplets evenly throughout the entire spray cone. This uniform distribution ensures smooth ignition, stable flame geometry, and highly efficient heat transfer while minimizing soot and carbon buildup.

• 80° Spray Angle: Provides a balanced flame profile that optimizes heat distribution within standard-sized combustion chambers and heating coils, ensuring maximum heat transfer to the water or air.

• Premium Bi-Metal Construction: Features a heavy-duty brass body for rapid heat dissipation (preventing fuel varnishing and residue buildup) combined with a precision-machined stainless steel internal metering section for maximum wear resistance.

• Integrated Sintered Filter: Equipped with a built-in mesh strainer at the base of the nozzle body to capture microscopic sediment, rust, and fuel impurities before they can reach the orifice, maintaining a consistent flame profile.

• Color-Coded Blue Cap: Standardized color coding by Delavan indicates a “Type B Solid Cone” nozzle configuration, allowing technicians to quickly identify the correct part during routine maintenance.
