Overview
The trunnion(fixed) ball valve ball has another stem at the bottom to fixed the position of the ball, so the ball can’t move. When the trunnion ball valve is closed, the ball does not produce displacement.
The trunnion ball valve is a kind of double-block-and-bleed(DDB) valve, while the floating ball valve only seal the downstream side.The trunnion ball valve can block both upstream and downstream media. And when the pressure in the middle cavity is greater than the seat spring force, the seat will be pushed open to release the pressure inside the chamber to ensure safety.
The trunnion ball valve can be used in high pressure conditions and the size can be up to 60 inches.
