Introduction of electric control valve

Electric control valve is an important executive unit instrument in industrial automation process control. With the increasing degree of automation in the industrial field, it is being used more and more in various industrial production fields. Compared with the traditional pneumatic control valve, it has obvious advantages: the electric control valve is energy-saving (consumption of electricity only when working), environmental protection (no carbon emissions), and quick and convenient installation (no need for complicated pneumatic pipelines and air pump workstations). According to the power used by the actuator, the valve is divided into three types: linear characteristic, equal percentage characteristic and parabolic characteristic according to its function and characteristics.

How Folding Works

Working power supply: DC24V, AC220V, AC380V and other voltage levels.

Input control signal: DC4-20MA or DC1-5V.

Feedback control signal: DC4-20MA (load resistance below 500 ohms)

By receiving the signal of the industrial automation control system (such as: 4-20mA) to drive the valve to change the cross-sectional area between the valve core and the valve seat to control the flow, temperature, pressure and other process parameters of the pipeline medium. Realize automatic adjustment function.

The new electric control valve actuator contains the function of feeding clothes, accepts a unified 4-20mA or 1-5V·DC standard signal, converts the current signal into a corresponding linear displacement, and automatically controls the opening of the control valve to reach the pipeline Continuous adjustment of process parameters such as internal fluid pressure, flow, temperature, and liquid level.
