Electric Actuator With Ball Valve
The Working Principle Of Ball Valve
The opening and closing part of the ball valve is a sphere with a circular channel, which rotates around an axis perpendicular to the channel. The ball rotates with the valve stem to achieve the purpose of opening and closing the channel. The ball valve only needs to be rotated 90 degrees and a small rotational torque to close tightly. According to the needs of working conditions, different driving devices can be assembled to form ball valves with various control methods, such as electric ball valves, pneumatic ball valves, hydraulic ball valves, etc.
When the ball valve rotates 90 degrees, the inlet and outlet should all present spherical surfaces, thereby closing the valve and cutting off the flow of the medium.

Types And Classifications Of Ball Valves
A ball valve is a valve with a ball as a closing member. It is mainly composed of a valve body, a valve seat, a ball, a valve stem, a handle (or other driving devices, such as electric actuators, pneumatic actuators or hydraulic actuators). The valve stem drives and rotates around the axis of the ball valve. It is mainly used to cut off, distribute and change the flow direction of the medium in the pipeline.
There are many types of ball valves, including different working principles, media used, and application locations. Users should choose different types of ball valves according to the working conditions. The types of ball valves are classified according to the actual working conditions on site.
