Abstract:
An overfill valve associated with a drop tube segment fluidly connected to a fluid reservoir is described. The overfill valve includes a valve body positioned within the drop tube segment and a non-contact valve actuator positioned exterior to the drop tube segment and operable to actuate the valve body from an open position to a closed position without requiring any physical penetration through the wall of the drop tube segment. The non-contact valve actuator has a first position in which the non-contact valve actuator does not actuate the valve body from the open position to the closed position in a second position, achieved when the liquid reservoir reaches a predetermined level approaching the capacity of the liquid reservoir, the non-contact valve actuator actuating the valve body from the open position to the closed position when the non-contact valve actuator obtains the second position.
