What are the control methods for electric actuators?

Electric actuators are an important type of actuator, consisting of an actuator and a regulating valve. It is composed of a servo system scheme, where the signal from the regulator drives the motor through the servo amplifier, drives the regulating valve through the reducer, and feeds back the stroke of the valve stem to the servo amplifier through the position transmitter, forming a position servo system. By relying on negative position feedback, it ensures that the input signal is accurately converted into the stroke of the valve stem.

Advantages and disadvantages of pneumatic and electric control valves

The difference between pneumatic control valves and electric control valves is as follows: 1. Performance characteristics of electric control valves: Electric control valves are composed of electric actuators and control valves, and their main characteristics are: 1. Light weight and beautiful appearance. 2. Functionally, it can replace many products with incomplete functions, simplify the design, and solve the shortcomings of complex factory management, complex selection, and heavy maintenance workload.

What are the four good uses of analyzing fluorine lined butterfly valves?

Four advantages of fluorine lined butterfly valves: Firstly, the butterfly plate of the fluorine lined valve is installed in the diameter direction of the pipeline. In the cylindrical channel of the butterfly valve body, the disc shaped butterfly plate rotates around the axis, with a rotation angle between 0 ° and 90 °. When the rotation reaches 90 °, the valve is fully open.

Five major issues to pay attention to during pressure test of regulating valves

Attention should be paid to the pressure test of the regulating valve: 1. The pressure test of the regulating valve body should be carried out using a manual pressure testing pump for water pressure test, and it is strictly prohibited to use an electric pressure testing pump. 2. The test medium is clean water.

Definition of electric actuators

The most widely defined electric actuator is a driving device that can provide linear or rotational motion, utilizing a certain driving energy source and working under a certain control signal. Electric actuators use liquid, gas, electricity, or other energy sources and convert them into driving effects through motors, cylinders, or other devices.
