Stiefel Oil Burners: Exceptional Efficiency & Global Support | Industrial Heating

Equally important, Stiefel’s solenoids fuel coking prevention features double-block structures with self-cleaning mechanisms to ensure burner oil safety. Tungsten carbide seats are used because of their ability to maintain tight seals after 500,000 cycles and resist coking wear from abrasive particles found in waste oil. Our valves increased maritime boiler fuel leak performance from 95% to previous models leaks by 95% through metal-to-metal sealing and automated back-flush functions. Operating at 300°C, the valves retain reliability during long-duration firing cycles while 24V DC makes them suitable for marine electrical systems.
