Overview

The Schneider electric control valve actuator receives command signals from the regulator and converts them into corresponding angular or linear displacements through the actuator to manipulate the regulating mechanism and change the energy or material input and output of the controlled object, in order to achieve automatic control of the process. The actuator often operates under harsh conditions such as high temperature, high pressure, deep freezing, strong corrosion, high viscosity, easy crystallization, flash evaporation, cavitation, and high pressure difference. Therefore, it is the weak link of the entire control system.

Schneider Electric Control ValveThe function of the actuator:

The actuator receives command signals from the regulator and converts them into corresponding angular or linear displacements through the actuator to manipulate the regulator and change the energy or material input and output of the controlled object, in order to achieve automatic control of the process. The actuator often operates under harsh conditions such as high temperature, high pressure, deep freezing, strong corrosion, high viscosity, easy crystallization, flash evaporation, cavitation, and high pressure difference. Therefore, it is the weak link of the entire control system.

The integrated linear electric actuator consists of isolated electrical parts and gear transmission parts, with the motor serving as the intermediate component connecting the two isolated parts. The motor outputs torque according to control requirements, which is transmitted to the trapezoidal screw through multi-stage spur gears. The trapezoidal screw converts torque into thrust through threads. There is a flagpole connected to the output shaft stop ring, which runs synchronously with the output shaft. The displacement of the output shaft is converted into an electrical signal through a rack plate connected to the flagpole, and provided to the intelligent control board as a comparison signal and valve position feedback output.

Electric control valve is an important execution unit instrument in industrial automation process control. Compared with traditional control valves, electric control valves have obvious advantages: energy-saving (only consuming electricity during operation), environmentally friendly (no carbon emissions), and easy to install (no need for complex pneumatic pipelines and air pump workstations).
