Electric handwheel ball valve is a handwheel rotation switching device ball valve of an electric actuator. The beneficial effect of the utility model is that the manual and automatic switching of the electric actuator is simple and the operation is more convenient. Adding a worm gear manual device prevents the valve cylinder from being powered off and the valve can be manually operated to make the pneumatic valve safer and more reliable. The execution speed of the electric actuator is relatively fast, and does not require workers to do it themselves, which saves human resources and time to a large extent.
