A dual temperature valve positioned in a bypass passageway can move to an open position when two temperature conditions are met. When opened, the dual temperature valve can allow warm fluid from a first line to mix with cold fluid from a second line to heat the same. The valve is preferably utilized

A dual temperature valve positioned in a bypass passageway can move to an open position when two temperature conditions are met. When opened, the dual temperature valve can allow warm fluid from a first line to mix with cold fluid from a second line to heat the same. The valve is preferably utilized in an engine fuel system and positioned in a bypass passageway extending between a fuel supply line and a fuel return line. In this application, the dual temperature valve can prevent possible fuel transfer problems, such as cold start gaseous circulation.
