The API 6D trunnion ball valve is a high-performance ball valve characterized by its trunnion-mounted ball design. This structure maintains the ball in a centralized position within the valve body during opening and closing operations, eliminating sliding friction between the ball and seats. Consequently, it significantly reduces torque requirements while enhancing sealing performance and service life of the valve.
