What is the working principle of electric valve actuator?

2022-11-05
Electric valve actuator, also known as valve electric device, is an actuator that uses electricity as the energy source in the control system. It receives electrical signals from regulating instruments, changes the amount of manipulation according to the size of the signal, and changes the amount of material or energy of the input or output control object to achieve automatic program adjustment. There are many types of actuators, such as multi rotation, partial rotation, straight through, angle through, etc.

The electric valve actuator is an important part of the automatic regulation system. It directly controls the delivery of materials or energy regulated media according to the command of the regulator. Its working principle is: the electric valve actuator takes the DC current as the control and feedback signal. When the upper instrument or computer sends a control signal, the electric actuator acts in proportion to the size of the signal, and opens the valve or damper to the corresponding opening through the output shaft, The system opening signal is fed back to the control room to complete the system regulation function.
