Abstract
A 3-position valve simultaneously supplies oil to a burner and supplies steam/air as an atomizing medium for the oil. The vapor valve element and oil valve element are positioned relative to their seats by a common stem system. After the oil valve element is seated and the oil thereby shut off, a position is given the vapor valve element to flow the vapor as a purging medium principally through the oil outlet line from the valve to the burner.
