The seat of the full bore ball valve is usually of elastic or metal seal construction, which closely fits the ball to ensure good sealing in the closed state. At the same time, in order to meet the requirements of the full bore, the inlet and outlet channels of the valve are also consistent with the ball through the hole and the inner diameter of the pipeline to ensure the smooth flow of the fluid.
