The CH series actuators can directly receive signals from computers or industrial instruments, such as 4â€“20mADC or 1â€“5VDC control signals, along with a 220VAC power supply. Based on the valve position feedback and setpoint error, the actuator drives the motor for intelligent step-by-step adjustment (PID control), ensuring precise positioning of the valve or other components. It also outputs a 4â€“20mADC position feedback signal. The core control unit uses advanced digital technology, integrating signal acquisition, processing, feedback, and control. An original electronic brake circuit and mechanical damping are added to eliminate inertia, enabling instant stop and no oscillation during positioning. Positioning accuracy can reach above 0.3%. SCR output ensures fast action, stable output, and high reliability. Its compact design, lightweight, and durable performance make it ideal for thick media containing particles or fibers. It is widely used in food, environmental protection, light industry, oil, paper, chemicals, teaching, and research equipment, as well as in electrical industries for industrial control.
