What is electric autuator?

The most extensive definition of executive agencies is: a driver that can provide straight or rotating motion, which uses some kind of driver energy and works under a certain control signal. The execution agency uses liquid, gas, electricity or other energy sources and converts it into a driver through motor, cylinder or other devices. There are three driving methods: part-turn, multi-turn, and linear (Linear).

Basic execution agencies are used to drive valves to the position of full or full level. The execution agency used to control valves can accurately make the valve walk to any position. Although most of the execution agencies are used for switching valves, the design of the execution agencies far exceeds simple switching functions. They include position sensing device, torque induction device, electrode protection device, logical control device, digital communication module And PID control modules, etc., and these devices are all installed in a compact shell.

Because more and more factories use automated control, manual operation is replaced by mechanical or automated equipment, people require that the execution agency can play the interface between control systems and valve mechanical movements. Environmental protection performance. In some dangerous occasions, automated execution agency devices can reduce personnel damage.

Some special valve requirements are urgently opened or closed under special circumstances. Valve execution agencies can prevent the danger from further diffusion and minimize factory losses to minimum loss. For some high -voltage and large -caliber valves, the required execution mechanism has a very large output torque. At this time, the required execution agency must improve the mechanical efficiency and use high output motors to operate the large -caliber valve smoothly. For some small torque valves, the fine -sized electric valves are also applied. Compared with ordinary types, it has the advantages of light weight, compact structure, and complete function.
