Abstract
A disclosed is a 2-way 2-position fluid control valve assembly operable to manually open and automatically block fluid flow therethrough. The fluid control valve assembly includes a valve and an electromagnetic actuator having an armature and a pole piece. The valve is biased to its closed position whereat the armature is spaced away from the pole piece. The armature is manually movable to contact the pole piece while opening the valve. The armature and the pole piece are latchable together, with only residual magnetism, only when there is zero air gap or substantially zero air gap between the armature and the pole piece. When latched, the armature and the pole piece remain in that state until they are delatched by canceling at least enough of the residual magnetism so that the biased valve closes while the armature moves away from the pole piece.
