working principle

Rotate the handwheel anticlockwise. The driving thread in the handwheel and the driving thread on the bracket act. The handwheel pushes the valve stem seat upward to open the valve. Adjust the opening height according to different working conditions on site. Rotate the handwheel clockwise to push the valve stem seat downward, so that the sealing ring of the valve seat presses the sealing plane of the lower valve body and closes the lower valve port. Different opening height results in different Kv value.
