API 6D Trunnion Ball Valve is a specialized ball valve design where the ball is not free-floating as in a floating ball valve. Instead, it is secured within the valve body by two or more trunnions (typically bearings). This design keeps the ball in a fixed position during operation, preventing direct friction between the ball and the seats, thereby significantly reducing seat wear and extending the valve's service life. Additionally, the trunnion structure enables the valve to withstand higher pressures, making trunnion ball valves particularly suitable for high-pressure, large-diameter applications.
