| Comparison Items | Trunnion Mounted Ball Valve | Floating Ball Valve |
| Ball | The ball has a fixed shaft at the bottom, and its position is fixed. | The ball only has an upper valve stem, no fixed shaft, and can displace under the action of medium pressure. |
| Sealing Mechanism | The medium pressure drives the valve seat to move and closely adhere to the ball for sealing. | The ball is pressed tightly against the outlet - end valve seat sealing surface under the action of medium pressure to achieve sealing. |
| Seat Structure | There are often springs at the end of the metal valve seat, and valves above 4 '' usually have grease injection valves. | The structure is relatively simple, with fewer compensation structures such as springs, and generally no grease injection valves. |
