Is the butterfly valve suitable for flow regulation

The butterfly valve has a small flow resistance when fully opened. When opened between about 15°~70°, sensitive flow control can be carried out, so in the field of large diameter adjustment, the application of butterfly valves is very common. Due to the wipeability of the butterfly plate movement, most butterfly valves can be used in media with suspended solid particles. Depending on the strength of the seal, it can also be used for powder and granular media. Butterfly valves are suitable for flow regulation. Because the pressure loss of the butterfly valve in the pipe is relatively large, about three times that of the gate valve, the influence of the pipeline system by the pressure loss should be fully considered when selecting the butterfly valve, and the strength of the butterfly plate under the pipeline medium pressure should also be considered when it is closed. In addition, the operating temperature limitations of the elastic seat material at high temperatures must be considered.
