Abstract
A shut off valve () is provided for use in an aircraft lavatory system () during maintenance sanitizing operations. The shut off valve includes an inlet passage () in intermittent fluid communication with an outlet passage () and a magnetic flapper body () movable between a rest position and a seal position between said inlet passage and said outlet passage. The flapper body is moved by a magnetic actuator () whereby upon placing said magnetic actuator within the proximity of the flapper body, the flapper body is moved form the rest position and, with the assistance of fluid flow within the valve, into the seal position, thus preventing fluid communication between the inlet passage and the outlet passage.
