Shanghai Automation actuator

Shanghai actuator uses liquid, gas, electricity or other energy and converts it into driving action through motor, cylinder or other devices. The basic actuator is used to drive the valve to the fully open or fully closed position. The actuator with the control valve can accurately make the valve go to any position. Although most actuators are used to switch valves, the design of today's actuators goes far beyond simple switching functions. They include position sensing devices, torque sensing devices, electrode protection devices, logic control devices, digital communication modules and PID control modules, all of which are installed in a compact shell.

The most extensive definition of the actuator is: a driving device that can provide linear or rotary motion, which uses a certain driving energy and works under the action of a certain control signal.

Because more and more factories have adopted automatic control, and manual operation has been replaced by machinery or automatic equipment, people require the actuator to act as the interface between the control system and the mechanical movement of the valve, and they also require the actuator to enhance the performance of work safety and environmental protection. In some dangerous situations, automatic actuator devices can reduce personal injury. Some special valves require emergency opening or closing under special circumstances, and the valve actuator can prevent the further spread of danger and minimize plant losses. For some high-pressure large-diameter valves, the required actuator output torque is very large. At this time, the required actuator must improve mechanical efficiency and use high output motors to operate large-diameter valves smoothly.
