operational principle

Rotate the handwheel counterclockwise, and the transmission thread inside the handwheel and the transmission thread on the bracket act. The handwheel pushes the valve stem and seat up to open the valve, and the opening height is adjusted according to different working conditions on site; Rotate the handwheel clockwise to push the valve stem and seat down, causing the seat sealing ring to compress the sealing surface of the lower valve body and close the lower valve port. Different opening heights result in different KV values.
