The flow characteristic of an electric control valve is the relationship between the relative flow rate of the medium passing through the electric control valve and its opening, under the condition that the pressure difference at both ends of the valve remains constant.

　　The flow characteristics of electric control valves include linear characteristics, equal percentage characteristics, and parabolic characteristics.

Installation instructions for electric control valve:

　　The electric control valve is suitable for installation as the upper end of the working piston is located below the horizontal pipeline. The temperature sensor can be installed in any position, and the entire length must be immersed in the controlled medium.

　　Electric control valves generally include drivers that receive driver signals (0-10V or 4-20MA) to control the valve for adjustment. They can also form an intelligent network control system according to control needs to optimize control and achieve remote monitoring.
