Performance:
1. In the closed position, the ball is pressed against the valve seat by the mechanical pressure of the valve stem.
2. When open the valve, the valve stem moves in reverse, and the angular plane at the bottom makes the ball disengage from the valve seat.
3. The stem continues to lift and interacts with the guide pin in the spiral groove of the stem to make the ball start to rotate without friction.
4. Until the fully open position, the valve stem is raised to the limit position, and the ball rotates to the fully open position.
5. When closed, turn the handwheel clockwise, the valve stem starts to lower and the ball leaves the valve seat and starts to rotate.
6. Continue to rotate the handwheel, the valve stem is subjected to the guide pin embedded in the spiral groove on it, so that the valve stem and the ball rotate 90 ° at the same time.
7. When it is about to close, the ball has rotated 90 ° without contact with the valve seat.
8. In the last few rotations of the handwheel, the angled plane at the bottom of the valve stem mechanically wedges the ball, pressing it tightly against the valve seat to achieve a complete seal.
