The working process of API 6D trunnion ball valves can be divided into two stages: opening and closing. When the valve is closed the valve ball and valve seat close fit, preventing the flow of media. When the valve is open, the torque is applied by the operating device to make the valve ball rotate, thus separating it from the valve seat, so that the quality can flow through the valve.
