The Intelligent electric actuator integrates a digital control board and LCD display system, supporting local parameter configuration, real-time opening display, and automatic fault diagnosis. It is compatible with multiple communication protocols including 4-20mA analog signals, HART bus, and RS485, allowing direct connection with factory DCS and PLC automation systems.
The built-in high-precision position sensing module provides excellent adjustment linearity. Multiple safety functions including fault self-diagnosis, signal loss protection, overheating protection, overload protection, and valve position limiting ensure reliable operation under complex industrial conditions.
Large torque models are suitable for large-diameter high-temperature and high-pressure control valves, while compact models support precise micro-flow adjustment. All models are equipped with local manual operation mechanisms and support switching between remote and local control modes.
Application Areas:
Large petrochemical process units, power plant steam regulation systems, intelligent coal chemical production lines, lithium battery automated manufacturing equipment, continuous pharmaceutical production systems, and smart metallurgical cooling networks.
