OPD Valves

On the outside of the cylinder there is a gadget called the OPD, the overfill prevention gadget. Inside the tank is this gadget that acts as a float. It floats to the top when the tank has reached maximum capacity. 

The propane distributor has a mathematical formula that is utilized to establish that the tank is full. The container knows that the tank is full when a white mist is transmitted out of a small opening on the OPD valves. 

The overfilling prevention gadget has upset and greatly increases the safety of utilizing propane cylinders at home or in a business. The gadget actually stops the filling cycle when propane tanks are about 80 percent full. 

This is important because it leaves sufficient space in the tank to allow for the expansion and contraction of fuel when the tanks are presented to different temperatures.
