China Reduced bore ball valve manufacturer, factory and supplier. In reduced bore ball valves, flow through the valve is one pipe size smaller than the valve's pipe size resulting in flow area becoming lesser than pipe. But the flow discharge remains constant as it is a multiplier factor of flow discharge is equal to area of flow into velocity. the velocity increases with reduced area of flow and decreases with increased area of flow.
The biggest difference between the full bore ball valve and the reduced bore ball valve is that the flow passage of the former is the same size as the pipeline, and its size cannot be smaller than the standard value, which is roughly equivalent to the nominal diameter of the ball valve. For example, the flow passage size of DN50 full bore ball valves is about 50mm. The flow area of the reduced bore ball valve is smaller than the pipe.
