As for the characteristics of the electric ball valve, it is similar to the plug valve, except that its closing part is a sphere. The ball valve operates around the center line of the valve body to achieve the purpose of opening or closing. 　　

The pneumatic ball valve includes the main valve body, the auxiliary valve body and the pneumatic actuator. The main valve body and the auxiliary valve body of the product are fixedly connected. The main valve body and the auxiliary valve body of the product are provided with an annular seal ring, and also include a spherical valve core. The spherical valve core of the product is connected with the pneumatic actuator through the valve stem. One side of the spherical valve core of the product is provided with a plane parallel to the axis of the valve stem, The other side opposite to the plane of the product is provided with a V-shaped scheduling slot. The bottom of the V-shaped scheduling slot of the product coincides with a diameter of the spherical valve core of the product and is perpendicular to the axis of the valve stem. There are valve seats between the spherical valve core of the product and the main valve body and the auxiliary valve body of the product respectively. The pneumatic actuator of the product is fixed on the main valve body through a bracket, A sealing element is arranged between the cylinder surface of the valve rod and the main valve body of the product, and the sealing element of the product is pressed by a gland. This equipment has simple manufacturing process, low cost, and good sealing performance. A V-shaped scheduling slot is set on the spherical valve core. During operation, the flow can be controlled by scheduling the rotating viewpoint of the spherical valve core.
