Angular stroke electric actuator is an instrument used in automatic control systems to manipulate and change the displacement of the control mechanism (valve) based on changes in the control instrument signal. The DKJ type angular stroke electric actuator can be used in conjunction with transmitters, regulators, and other instruments. It is powered by a power source, receives 4-20mADC or 0-10mADC signals, converts them into angular displacement corresponding to the input signal, and automatically operates adjustment mechanisms such as dampers, butterfly valves, ball valves, etc. to complete automatic adjustment tasks, or is equipped with an electric operator for remote manual control. This actuator and its accessories can be widely used in the control systems of industrial sectors such as power plants, steel plants, chemical plants, and light industries. Angular stroke electric actuators have three control modes: continuous adjustment, remote manual control, and local manual operation. The angular stroke electric actuator produced by Shanghai Yihuan is suitable for places with non corrosive gases, ambient temperatures ranging from -25 ℃ to+70 ℃, and relative humidity ≤ 95%.
