AS1002F-04: Intelligent Regulation, Precision Flow Control! Electric Control Valve Empowers High-Precision Process Control​

In process automation requiring precise regulation of flow or pressure, control valves must meet extremely high demands for accuracy, response speed, and intelligent control capabilities. The AS1002F-04 Electric Control Valve integrates a high-precision actuator, intelligent positioner, and high-quality valve body into a single unit. By receiving control signals, it enables continuous and precise adjustment of fluid parameters, making it a key actuator for improving process quality and achieving intelligent control.​​Core Product Advantages​​​​High-Precision Electric Regulation​​Utilizes a stepper motor or servo motor drive, providing high spool displacement control accuracy (up to ±0.5% FS) and supporting seamless, precise regulation of flow/pressure.​​Intelligent Closed-Loop Control​​Features a built-in position feedback sensor (e.g., potentiometer, encoder) for real-time valve position monitoring and automatic calibration. This ensures close alignment between the set value and actual output, with strong anti-interference capability.​​Optimized Linear Characteristics​​The specially designed spool curve (e.g., equal percentage, linear) offers excellent flow characteristics, meeting the regulatory needs of different working conditions and ensuring control linearity and stability.​​Digital Communication Integration​​Supports analog signal input (4-20mA / 0-10V). Some models integrate digital communication protocols like RS485, PROFIBUS, or Modbus, enabling remote parameter configuration, real-time monitoring, and fault diagnosis.​​Corrosion-Resistant & Wide Compatibility​​The valve body is constructed from stainless steel or carbon steel, with seals made of EPDM or Viton. Suitable for various media including water, steam, and gases, offering good corrosion resistance.​​Typical Application Scenarios​​

• ​​Process Control:​​ Precise flow/pressure regulation for reactor feeding, pH adjustment, and temperature control in chemical and pharmaceutical production.
