ABSTRACT:
A fluid control valve includes a valve member movable into engagement with a seating to prevent the flow of fluid through the valve, and an actuating member which is biased in one direction by a return spring and is moved against the action of the return spring by the armature of the actuator when the winding thereof is energized. The movement of the actuating element is transmitted to the valve member through an under travel spring which yields to allow continued movement of the actuating element when the valve member engages the seating.
