Description

The Delavan 4.00 GPH 80° Type B Solid Cone Fuel Nozzle (identified by its blue protective cap) is a high-capacity, heavy-duty combustion component. It is engineered for large-scale heating applications, industrial boilers, and maximum-output hot water pressure washers, where it atomizes fuel to deliver clean, efficient, and stable heat generation.

With a high flow rate of 4.00 GPH, this nozzle is designed for large-capacity combustion chambers and heating coils that require substantial thermal energy to heat high volumes of water or air rapidly.

Key Features

• Type B Solid Cone Pattern: Distributes atomized fuel droplets evenly throughout the entire spray cone. This uniform distribution ensures smooth ignition, excellent flame stability, and maximum heat transfer efficiency while minimizing soot or carbon buildup.

• 80° Spray Angle: Provides a balanced, standard-width flame profile that matches the internal geometry of large heating coils and combustion chambers, preventing the flame from directly impinging on the walls.

• Premium Bi-Metal Construction: Features a heavy-duty brass body for rapid heat dissipation (which prevents fuel varnishing and internal clogs) 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 pattern type during routine maintenance.
