Trunnion Mounted Ball Valve

        Ball valves are mainly used to cut off, distribute and change the flow direction of medium in the pipeline. It can be closed tightly with 90° rotation operation and small rotation torque. Ball valve is most suitable for switching and closing valve, v-type ball valve. In addition to the pipeline parameters, the electric valve should pay special attention to the environmental conditions. Because the electric device in the electric valve is an electromechanical equipment, its operating condition is greatly affected by its use environment. In general, the electric ball valve and butterfly valve shall be used in the following environment with special attention.
