Are There Differences and Connections Between Electric Actuators and Electric Valves?
Electric actuators and electric valves are different in function and application, but they frequently need to be used together in practical applications. Below is an overview of their main differences and connections.
Electric valves mainly use an electric actuator to open and close the valve and regulate the flow of media to meet different process requirements. While electric actuators use an electric drive to control the rotary or linear motion of industrial equipment, delivering the specific movement paths and positioning accuracy.
The internal structure of electric actuator is more complex, it consists of a motor, reduction mechanism, transmission system, guide rails, limit switches, and controller, etc. An electric valve generally comprises the electric actuator, valve body, check valve components, and electrical parts, making its overall structure relatively simpler.
Electric actuators can be applied across different operating environments and process requirements. They are commonly used to regulate parameters such as temperature, pressure, and liquid level, as well as to support material transporting and processing. Electric valves, however, are mainly used for shutting off, regulating, and distributing process media.
Although electric actuators and electric valves have obvious differences in functions and applications, they always need to be used together in actual applications. An electric actuator often works as a key component of an electric valve. By driving and controlling the actuator, the valve can achieve automatic control and precise flow regulation. In practice, electric actuators and electric valves are interdependent and work in coordination with each other.
In summary, electric actuators and electric valves differ in functions, structures, and typical use cases. However, they are designed to complement each other, working together to deliver accurate and efficient automation for industrial equipment.
