Product introduction:

The biggest difference between a full port ball valve and a reduced-diameter ball valve is that the full-bore ball valve is a constant-width flow passage, and its size cannot be less than the standard-specified value, which is roughly equivalent to the nominal diameter of the specification, such as the DN50 full-bore ball valve. The flow path diameter is about 50mm; the flow path inlet of the reduced diameter ball valve is wider than the flow path diameter, and the actual diameter of the flow path is about one specification smaller than the specification. For example, the DN50 reduced diameter ball valve flows to a diameter of about 38, which is roughly The specifications of the DN40 are equivalent. In process piping systems, most valves are designed to limit the flow to a certain range by making the flow path or area of ​​the closure element smaller than the inner diameter of the line. Some ball valves can be designed such that their internal flow passages are of sufficient size to allow the flow to pass through without any significant restrictions. This ball valve is called a full bore ball valve because its internal flow path is equal to the full area of ​​the inlet and the full bore ball valve is primarily used for switching. And open circuit conditions.
