The special ball valve is the one with flap swiveling around the valve axis through the valve stem. It has advantages of simple and compact design, reliable sealing, long service life and corrosion resistance. The torque is output by angular displacement actuator, and the valve opens/closes rapidly with good sealing effect. It is always used as a switch and shut-off valve, and is applicable for the pipelines with conveyed fluid or pulp containing containing suspended fibers or small solid particles. The valve can be controlled remotely. There are two types of special ball valves, namely, full plastic and steel lined type, and they are seen popular in the pulp fluid or corrosive medium pipelines of chemical, petroleum, pharmacy, electric power, and steel industries, etc.
