The structure of electric actuated ball valve
Electric actuated ball valve is a kind of fluid control valve, its structure is composed of valve body, ball, valve disc, valve stem, pneumatic components and electric motor. There is a sphere on the valve body, and a disc on the sphere, which can rotate according to the control of the motor, thereby controlling the flow of fluid. The valve stem is driven by an electric motor, and the power of the electric motor is transmitted to the valve clack through the pneumatic components, so as to realize the opening or closing of the valve clack. When the control signal of the motor changes, the valve stem also changes accordingly, thereby controlling the flow of fluid.

Working principle of electric ball valve
The electric actuated ball valve is a commonly used valve, which is composed of a ball and a driving mechanism. When the drive mechanism receives a signal, it converts the electricity into mechanical energy, pushing the ball to rotate, thereby changing the flow direction of the fluid.
The action process of the electric actuated ball valve is as follows:
1. After receiving the signal, the driving mechanism of the electric ball valve converts the electric power into mechanical energy and drives the ball to rotate;
2. When the sphere rotates, its two channels will change to form a new channel, so that the fluid will flow to the new channel;
3. When the ball rotates to a certain position, the flow direction of the fluid will change, so as to achieve the purpose of controlling the flow.

How to choose and customize the appropriate electric ball valve?
When selecting an electric ball valve, you must first identify the relevant parameters of the valve body based on the working conditions of the pipeline. These parameters must then be compared to the corresponding parameters of the control system and the valve body. Afterwards, the relevant parameters of the actuator can be identified.
The motorized ball valve is an electromechanical integrated device, which relies on the rotation of the motor to rotate the ball valve body. It consists of two parts, the actuator and the valve body, and is mainly used in pipelines with fluids under different working conditions. When selecting a valve body material, it is important to consider the medium of the pipeline, the temperature of the medium, the operating conditions, and any regulatory requirements; for instance, stainless steel valves are recommended for drinking water and food equipment, medical equipment, while UPVC ball valves may be used for seawater and corrosive liquids.

Additionally, ball valves can be divided into two categories based on their flow characteristics: quick-open switch-type and equal percentage or linear regulation. If you need a valve that simply cuts off or connects fluid, changes direction of medium flow, or adjusts the size of flow, you can use an adjustable flow control valve body. However, if you require a ball valve that has linear flow characteristics, with a “V” groove ball center, or any other special liquid or gas flow specifications, our company can select and customize one for you.
