The full bore ball valve has a constant-width flow, that is, the size of the pores from inflow to outflow is the same, and its size cannot be less than the value specified by the standard, which is roughly equivalent to the nominal diameter of the specification. For example, the flow diameter of the DN50 full-bore ball valves also needs to be around DN50.

What Is The Difference Between Reduced Bore And Full Bore Ball Valve ?



The major difference between a full bore valve and a reduced bore ball valve is as below:

For the full bore valve, the hole in the ball has the same internal diameter as the pipe, whereas a reduced bore valve has a smaller bore diameter than the internal diameter of the pipework it is on. For example, the bore size in a 4 inch full-port ball valve is 4 inch in internal bore, while the bore diameter in a reduced & standard ball valve is 3 inch in internal diameter.
