Shanghai Yi Rotork Electric Actuator is produce by Shanghai Automation Instrumentation Co., Ltd. The broadest definition of an actuator is a drive that provides linear or rotational motion that uses some kind of drive energy and works with some kind of control signal. The actuator uses liquid, gas, electricity or other energy sources and converts it into a drive through a motor, cylinder or other device. The basic types are partial rotation (Part-Turn), multi-turn (Multi-Turn) and linear (Linear).

The basic actuator is used to drive the valve to a fully open or fully closed position. The actuator used to control the valve is able to accurately move the valve to any position. The design of the actuator far exceeds the simple switching function. They include position sensing devices, asynchronous sensing devices, electrode protection devices, logic control devices, digital communication modules and PID control modules, all of which are mounted in one volume. Inside the enclosure.

Because more and more factories use automatic control, manual operation is replaced by mechanical or automation equipment, people are required to control the interface between the system and the mechanical movement of the valve, and the actuator is required to enhance work safety and environmental protection. performance. In some dangerous situations, automated actuators can reduce the risk of personal injury.

Some special valves require emergency opening or closing under special conditions, and the valve actuator prevents further spread of the hazard while minimizing plant losses. For some high pressure and large diameter valves, the required actuator output current is very large. In this case, the actuator must be mechanically efficient and use a high output motor in order to operate the large diameter valve stably. For some small valve valves, small and small electric valves are also used. Some common models have the advantages of light weight, exquisite structure and complete functions.
