sanitary electric ball valve is a type of valve that has an electric actuator to drive the valve stem to rotate and control the opening and closing of the ball. It can be remotely controlled and is easy to install and use. It is mainly used to control the flow and unclog the media in the pipeline. Its flow pipe is smooth and seamless inside, which can be used to transfer different medium in flanges, welded, quick-install, internal/external threads the food, biopharmaceutical fields.
Ball valve is a new type of valve that has been widely used in recent years. It has been widely used in food and beverage, pharmaceutical, petroleum, chemical, biological processing and other industry.Electric ball valve is a commonly used valve, it has the characteristics of quick disassembly, suitable for the need for quick switching occasions. This valve is usually driven by an electric actuator, which controls the opening and closing of the valve through the rotation of the ball.
When installing and using electric ball valves, the following points need to be noted:
The structure of the electric ball valve is simple, mainly composed of a wide body, a ball, a sealing ring and an electric actuator, it is easy to operate, can be controlled by the electric actuator to achieve the opening and closing of the valve, in addition, its sealing performance is good, can effectively prevent the leakage of fluid
The series ball valves are used for material transfer and control. This type of valve is extensively used in food, beverage processing and pharmacy, chemical industry.

1. Introduction to Electric Actuator Valves
An electric actuator valve is one of the most important components in modern industrial automation, providing precise, stable, and reliable control of fluid flow through electrically driven mechanisms. As industries continue to embrace automation and digitalization, the demand for accurate and programmable valve control has increased dramatically. Electric actuator valves—also known as motorized valves, electric valve actuators, or motor operated valves (MOVs)—play a crucial role in ensuring that pipelines, process equipment, and fluid systems maintain proper operating conditions.
Unlike pneumatic or hydraulic actuator valves that rely on air pressure or oil pressure, an electric actuator valve uses an electric motor to generate torque and position the valve. This type of valve control is ideal for situations requiring high accuracy, steady control, remote automation, and integration with smart systems such as SCADA, PLC, DCS, and IoT-based industrial platforms.
Today, electric actuator valves are used across various industries, including power generation, HVAC, chemical manufacturing, water treatment, petroleum refining, food processing, and pharmaceutical production. Their exceptional performance, low maintenance requirements, and intelligent features make them a preferred choice for modern process control.
2. Working Principle of an Electric Actuator Valve
An electric actuator valve consists of two major parts:
The electric actuator, which produces the motion
The valve body, which regulates fluid flow
When the actuator receives an electrical signal, the motor rotates or moves linearly, causing the valve to open, close, or position itself somewhere in between. The control signal can be:
On/Off control (Open/Close)
Modulating control (0–10V, 4–20mA, or digital control signals)
Intelligent control via fieldbus protocols (Modbus, Profibus, CANbus, Ethernet/IP)
Rotary electric actuators rotate the valve stem 90°, used for:
Ball valves
Butterfly valves
Plug valves
Linear actuators convert rotation into linear motion, ideal for:
Globe valves
Gate valves
Diaphragm valves
These advanced systems include:
Microprocessor control
Display screens
Built-in diagnostics
Data logging

Smart actuators enhance the functionality of an electric actuator valve by offering precise control and real-time monitoring, supporting predictive maintenance and energy optimization.
