680571-1 is a kind of electro-hydraulic actuator applicable for various valves. It features a small compact structure, light self weight, low power consumption, high application flexibility and long service life. The communication module is able to support different industrial communication protocol, which makes it suitable for various communication network environment. Moreover, it is equipped with independent safety pole and heating core protection. This makes it being widely used in automatic control systems in many industries, like gas, metallurgical and chemical industry.

Operation Principle

The actuator\'s working principle is when the power is on, the control processor will receive the control signal which regulated by the upper control system, then send out controlling pulse signal to the thyristor control transformer, and then it will convert the current and regulate it to the linear motion of spool in the actuator, so the cylinder pressure towards the setting input direction can be controlled. The position sensor with non-contact measurement can achieve exact feedback, and the regulator can make sure that the object becomes more close to the working pressure.

Application Field

Due to the flexible control way, accurate feedback, custom setting and easy installation, 680571-1 actuator has been widely used in factories, water treatment systems, building automation and fuel systems, off shore equipment, fire fighting system, oil refinery, chemical production facility, process control and many other industrial field.

In addition, it can also be used for controlling pipe gate valve, spherical valve, oval strainers, air-condition units, ventilation valve, and other large-diameter industrial valves. It is reliable, energy efficient and fully adjustable, and can easily meet the demand in many industrial application.

Conclusion

680571-1 actuator is a compact and intelligent electro-hydraulic actuator, with reliable and accurate characteristics. It is suitable for various control valves, and can be applied in quite a few industrial application. With its fast reaction time, accurate feedback, easy installation and custom setting ability, this actuator is a perfect solution for various industrial automatic control system.
