OPW Ball Float Inspection Reference Material The 30MV series is designed to meet EPA's requirement to notify the delivery driver of an overfill 30 minutes prior to the overfill occuring. The 30MV will have a 1/16 inch breather hole. The 53V series is designed to alert the driver of an overfill by restricting flow when the tank reaches 90% of the liquid capacity. The 53V will have a 1/8 inch breather hole. Specifying the Proper Length 53V Ball Float Step 1: Determine Dimension "X": Consult the tank chart (provided by the tank manufacturer) to determine the distance that corresponds to 10% of the total tank capacity Step 2: Determine Dimension "Y": Measure the dimension from the inside top of the tank to the top of the 4" threaded tank "bung" fitting. Step 3: Add measurements "X" and "Y". Then subtract 1/4" and round up to the nearest length ball float. Specifying the Proper Length 30MV Ball Float Step 1: Determine Dimension "X": Consult the tank chart (provided by the tank manufacturer) to determine the distance that corresponds to 308 gallons. Step 2: Determine Dimension "Y": Measure the dimension from the inside top of the tank to the top of the 4" threaded tank "bung" fitting. Step 3: Add measurements "X" and "Y". Then subtract 1/4" and round up to the nearest length ball float.
