Electromagnetic regulating valves are critical control units in industrial automation processes. As the level of automation in industrial fields continues to rise, they are increasingly used in various industrial production sectors. Compared to traditional pneumatic regulating valves, they offer distinct advantages: energy-efficient (consume electricity only when in operation), environmentally friendly (no carbon emissions), and easy to install (no need for complex pneumatic pipelines and compressor workstations). Valves are categorized according to the power source of the actuator they are paired with, and by their functions and characteristics into three types: linear characteristics, proportional characteristics, and parabolic characteristics.
