ULLAGE (VAPOR SPACE) VALVES
Dometic patented “ullage valves” provide 3 functions for a compliant marine fuel system.
• The primary function is to drive fuel up the fill hose to activate the automatic fuel nozzle shut off during refueling. • Their secondary function is to maintain an exact expansion space within installed marine fuel tanks. This space allows for fuel expansion as
the diurnal temperate rises and protects sensitive system components from contamination. • Additionally, BluSkies ullage valves provide the best spit-back and well-back protection of any marine fuel system. Lastly they provide
adequate venting for vessels to meet ABYC H-24 Standards.
