Is Butterfly Valve Suitable For Flow Regulation?
When the butterfly valve is fully opened, the butterfly valve on the centerline of the support ear has a small flow resistance. When opened between approximately 15 ° to 70 °, it can also perform sensitive flow control, making butterfly valves widely used in the field of large-diameter regulation. Due to the wiping nature of the butterfly valve disc movement, most butterfly valves can be used for media with suspended solid particles. According to the strength of the sealing element, it can also be used for powder and granular media. Butterfly valves are suitable for flow regulation. Due to the large pressure loss of butterfly valves in the pipeline, which is about three times that of gate valves, when selecting butterfly valves, the impact of pressure loss on the pipeline system should be fully considered, and the strength of the butterfly plate to withstand the pressure of the pipeline medium when closed should also be considered. In addition, it is also necessary to consider the limitations of the working temperature that elastic seat materials can withstand at high temperatures.
