1 Pneumatic ball valve structure Pneumatic ball valve is evolved from plug valve. Its opening and closing parts, as a ball, use the ball to rotate 90 degrees around the axis of the valve stem to achieve the purpose of opening and closing.

Anti static structure: when operating the valve, the friction between the ball and the valve seat will produce electrostatic charges and accumulate on the ball. In order to prevent electrostatic sparks, an electrostatic device is specially set on the valve to export the charges accumulated on the ball
