Abstract
A solenoid-operated valve for use with fuel cells has a valve housing made of aluminum, for example and having first through third heating medium passages defined therein. A valve seat disposed in and fastened to the valve housing is made of stainless steel, for example. A valve head has a disk which can be seated on and unseated off a valve seat member of a valve seat. The valve head is coupled by threaded surfaces to the distal end of a movable member which is displaceable when a solenoid is energized. The movable member is made of a magnetic metallic material, and the valve head is made of a corrosion-resistant metallic material such as stainless steel or the like, for example.
