Electric regulating valve is an important execution unit instrument in industrial automation process control. With the increasing degree of automation in the industrial field, it is being more and more used in a variety of industrial production fields. Compared with the traditional pneumatic regulator valve has obvious advantages: the electric regulator valve energy saving (only consumes electricity), environmental protection (no carbon emissions), fast and convenient installation (no need for complex pneumatic pipeline and gas pump workstation). According to the power used by the actuator, the valve is divided into linear characteristics, equal to percentage characteristics and parabolic characteristics.

1. With the characteristics of small volume, light weight, simple connection, large flow rate and high adjustment accuracy, it is widely used in the industrial process automatic control system in electric power, petroleum, chemical industry, metallurgy, environmental protection, light industry, teaching and scientific research equipment industries.

2, flow characteristics: straight line characteristics, equal percentage characteristics or fast opening characteristics.

3, using the power supply is convenient and economical, saving a series of costs to establish a gas source station;

4. From the economic point of view, in addition to saving the cost of gas source station, but also save the cost of electrical valve positioner;

5. The link is reduced, and the maintenance workload is reduced accordingly.
