Product Overview

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 areas. Compared with the traditional pneumatic control valves have obvious advantages: electric control valves energy saving (only in the work of electrical energy consumption), environmental protection (no carbon emissions), quick and easy to install (no need for complex pneumatic piping and air pump workstations). Valve according to its matching actuator using the power, according to its function and characteristics are divided into linear characteristics, equal percentage characteristics and parabolic characteristics of the three.

Product features

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

2, flow characteristics: linear characteristics, equal percentage characteristics or fast-open characteristics.

3、Using the power supply is both convenient and economical, eliminating a series of costs to establish a gas station;

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

5, the link is reduced, the corresponding reduction in maintenance workload.
