The extended stem butterfly valve is a common fluid control device, which is characterized by a long shaft, which can be rotated to adjust the on-off of the fluid. The valve uses a butterfly plate as a shut-off element, through the shaft and the handle or motor connection, to achieve the control of the pipeline fluid.
