Tips: What is a handle butterfly valve?
The handle butterfly valve is simple in structure, small in size and light in weight, and only consists of a few parts. Moreover, it can be quickly opened and closed by only rotating 90°, and the operation is simple. At the same time, the valve has good fluid control characteristics. When the butterfly valve is in the fully open position, the thickness of the butterfly plate is the only resistance when the medium flows through the valve body, so the pressure drop generated by the valve is very small, so it has good flow control characteristics.
