Abstract

An overfill prevention valve for use with a tank includes a valve element disposed in a fluid fill path and a float assembly including an actuator and a repositionable float. The float is selectively fixed relative to and moveable relative to the actuator to adjust a target fill level. The float is buoyantly supported by the fluid such that the float and the actuator are shiftable in correspondence with an actual fill level. The actuator is coupled with the valve element such that the valve element shifts to a closed position when the actual fill level nears a target fill level. The float includes discrete buoyant components that are shiftable away from each other and from the actuator to facilitate shifting of the float relative to the actuator and that are securable relative to each other and relative to the actuator to facilitate operation of the float assembly.
