About the electric control valve introduction

The electric control valve is an important actuator unit in industrial automation process control. With the increasing degree of automation in the industrial field, more and more applications are being applied in various industrial production fields. Compared with the traditional pneumatic control valve, it has obvious advantages: the electric control valve can only consume electricity when it is working, it is environmentally friendly (no carbon emission), and it is quick and convenient to install (no complicated pneumatic piping and air pump workstation).
    working principle
    Working power: DC24V, AC220V, AC380V and other voltage levels. 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. Implement automatic adjustment functions.
    The flow characteristic of the electric regulating valve is the relationship between the relative flow rate of the medium flowing through the electric regulating valve and its opening under the condition that the pressure difference across the valve is kept constant. The flow characteristics of the electric control valve are: linear characteristics, equal percentage characteristics and parabolic characteristics.
