Abstract
An overflow protection device includes a valve body having an inlet conduit passing vertically therethrough. The inlet conduit includes an outlet end below a valve chamber. A valve within the valve chamber is movable between and open and closed position. A float is pivotally mounted below the valve and the float cams, an actuator upwardly when the float experiences a less than full tank and cams the actuation downwardly to permit the valve to move downwardly when the float rises to a predetermined level as it floats on the liquid within the tank.
