Overfill prevention valve

An overfill prevention valve configured for use with a tank defining an interior chamber, said chamber configured to contain a fluid defining an actual fill level, said valve comprising:

• an inlet element at least in part defining a fluid fill path;
• a valve element shiftable between open and closed valve element positions, wherein the valve element at least substantially prevents flow along the fluid fill path when in the closed valve element position;
• and
• a float assembly including an actuator and a repositionable float configured to be selectively fixed relative to and moveable relative to the actuator to adjust a target fill level,
• said float configured to be buoyantly supported by the fluid such that the float and the actuator are shiftable in correspondence with the actual fill level,
• said actuator being operably coupled with the valve element such that the valve element shifts to the closed valve element position when the actual fill level nears the target fill level and the actuator has shifted to a valve shut-off position,
• said float being shiftable away from the actuator to facilitate shifting of the float relative to the actuator,
• said float being securable relative to the actuator to facilitate operation of the float assembly,
• one of said actuator and said float including a first complementary element,
• the other of said actuator and said float including a plurality of second complementary elements spaced in a direction extending along the length of the actuator,
• each of said second complementary elements at least in part defining a discrete float calibration position,
• said complementary elements configured to engage one another to selectively fix the float relative to the actuator at a selected one of the float calibration positions, wherein the selected one of the float calibration positions corresponds to the target fill level.
