The most common definition of electric actuators is: a driving device that can provide linear or rotary motion, which uses a certain driving force and performs tasks under a certain control signal. In some risky places, automated electric actuators The device can increase personnel damage. Although most electric actuators are used to open and close valves, the design of today's electric actuators far exceeds the complex switching functions. They include position sensing devices, torque sensing devices, and electrode maintenance. Device, logic control device, digital communication module and PID control module, etc. All of these devices are installed in a compact housing. The basic electric actuator is used to drive the valve to the fully open or fully closed position.
The electric actuator uses liquid, gas, electricity or other power and converts it into a drive through a motor, cylinder or other device.The electric actuator used to control the valve can accurately make the valve go to any position.
As more and more factories adopt automatic control and manual operations are replaced by machinery or automation equipment, people require electric actuators to play the role of the interface between the control system and the mechanical movement of the valve. They also require electric actuators to enhance the safety of their tasks. Function and environmental maintenance function. Some special valves require emergency opening or blocking under special conditions. The valve electric actuator can prevent the risk from spreading further and minimize factory losses. For some high-pressure large-caliber valves, the required The input torque of the electric actuator is very large. At this time, the required electric actuator must improve the mechanical efficiency and use a high-input motor to operate the large-caliber valve smoothly.
