Product Description
Temperature difference Type, 3-Way DN20(PN16) Connection Electric Drive Linear HVAC Valve Actuator
1. The temperature communication actuator is an intelligent control actuator driven by a brushless motor. It is mainly used to control the temperature difference between the supply and return water of the fan coil. PID control function is adopted to ensure real-time performance, speed, and regulation stability.
2. Even if the communication is interrupted, the automatic control can still be maintained to ensure the control system's safety.
3. The return water temperature does not reach the set temperature, the actuator, according to the temperature difference, stepless adjustment of the actuator opening finally ensures a constant return water temperature difference.
4. Return water temperature set to 2-45℃ (can be changed through Modbus protocol).
5. The actuator with high precision and multi-function and field bus function is adopted. The parameters of the actuator can be set by fieldbus, and the functions of the actuator can be controlled by fieldbus or analog input.
