Abstract
A valve assembly () comprises a valve body (), a first valve (), a second valve (), and a manual override device (). The valve body () defines a first inlet (), a second inlet (), and an outlet (). Each valve () includes a plunger () that is electrically movable between a position whereat the corresponding inlet () communicates with the outlet () and a position whereat the inlet () is sealed from the outlet (). The override device () is manually movable to override positions whereat the electrical control of one of the valves () is overridden and the plunger's seat-sealing surface () is caused to move so that the corresponding inlet () communicates with the outlet ().
