The electric regulating valve is mainly composed of valve body, sleeve, valve disc, valve stem and other parts. There are through holes in the valve seat and the valve seat. Equipped with zkj or other types of electric angular travel actuator, it can complete remote control and automatic control. Electric regulating valve is widely used in water supply pipeline for conditioning and saving energy, and can also be used in oil pipeline. The internal heat generated by the motor operation of the electric regulating valve will lead to thermal protection and stop the operation of the electric regulating valve. Because it is necessary for the motor to output torque through multi-stage deceleration, the running speed is not very fast, and it is not applicable in some occasions requiring fast opening and closing. Large torque and high speed are still a relatively difficult contradiction; because there are many moving parts, it is relatively easy to generate In this case, it is better to choose pneumatic regulating valve.
