At the forefront of nozzle development, Delavan created its nozzle using bi-metal construction. The Brass body and stainless steel metering parts permit machining to close tolerances for precision and consistently high performance. Brass transmits heat fast from the nozzle face to reduce the possibility of varnish and oil residue buildup. Stainless steel provides that extra durability for metering parts where wear is a factor. Type "A" nozzles are mainly used on burners with a hollow cone air pattern and for throughputs up to 2.00 GPH. The droplet distribution is concentrated on the outside of the cone and results in good ignition and low-noise combustion
