| ACTION STATE | HYDRAULIC DRIVE SITUATION | POSITION OF THE BALL | VALVE STATE | FLUID PATH SITUATION |
|---|---|---|---|---|
| Opening | The hydraulic system delivers pressurized oil to the actuator, and the piston displaces under the oil pressure | The channel of the ball coincides with the channel of the valve body | Open | The fluid medium passes through smoothly |
| Closing | The hydraulic system controls the piston to move in the reverse direction, driving the valve stem to rotate | The ball The ball rotates 90 degrees, and the channel is staggered with the channel of the valve body | Closed | The fluid path is cut off |
| Adjusting | Adjust the pressure and flow of the hydraulic oil to precisely control the movement of the piston | The ball rotates to a specific angle, changing the cross - sectional area of the channel | Flow regulation | Achieve different flow control |
