Operating principle of electric regulating valve

Operating principle of electric regulating valve

Power supply: DC24V,AC220V,AC380V, etc.
Input control signal: dc4-20ma or dc1-5v. Feedback control signal of electric regulating valve: dc4-20ma (load electrical obstruction less than 500 ohm)
By receiving industrial automation control system signals (such as: 4~20mA) to drive the valve to change the size of 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 feeding function, accepts the uniform 4-20ma or 1-5v ·DC standard signal, converts the current signal into the corresponding linear displacement, automatically controls the opening of the control valve, and achieves the continuous adjustment of the pressure, flow, temperature, liquid level and other process parameters in the pipeline.
Electric regulating valve flow characteristics
The flow characteristic of the electric control valve is the relation between the relative flow of medium flowing through the electric control valve and its opening degree under the condition that the pressure difference between the two ends of the valve remains constant.
Electric control valve flow characteristics: linear characteristics, equal percentage characteristics and parabolic characteristics of three.
