Butterfly valves have been used for shut-off and throttling-control application. It is found that the information available on loss coefficients of butterfly valves for good throttling control is limited at present. This report investigates the performance of two different configurations of butterfly valve: perforated blades and different diameter of solid blades that allow partial opening of the valve at closed position. The experimental results support the suitability of a butterfly valve for good flow control.
