This series of electric actuators offers three models to meet different needs. The ON/OFF type actuator employs 90-degree fixed-point rotation design which works for basic switch control; the regulating type actuator allows stepless 0-90 degree rotation for precise flow control; the intelligent actuator features LED display capable of showing real-time valve position on the regulating type. The entire series is designed for universal AC/DC dual power supply, standard signal control system, emergency manual operation, and maximum output torque of 4000Nm which addresses the intelligent control and heavy-load reliability demand.
