4. Screw rod: transmits the rotational force of the handwheel to the gate.

5. Handwheel: used to operate valves.

6. Packing box: used to seal the gap between the screw and the valve cover.

7. Bearing: supports the rotation of the screw rod.

8. Sealing gasket: used to seal various connections of the valve.
