E-Series Technical Features
The E-series intelligent electric actuator is an advanced execution device in the field of control, which can make operation easier, function more powerful, use more flexibly, and provide richer working status information.
Debugging of working parameters without opening the lid
After the actuator is assembled with the valve, it often needs to reset the valve's closing and opening positions, as well as set some working parameters, such as the valve's closing direction and the protective torque during the valve's closing or opening process. The parameter debugging without opening the cover not only greatly reduces the workload of on-site debugging personnel, but also prevents external dust, moisture, and harmful substances from entering the interior of the actuator, reducing the possibility of corrosion and oxidation of electronic circuits and low-voltage switch contacts, thereby greatly improving the service life and reliability of the actuator.
Multiple language display, accessible operation
The parameter settings, signal queries, status, and fault information of the actuator can be displayed correctly on the LCD screen according to the pre-agreed language, avoiding misunderstandings, misjudgments, and misoperations caused by language differences, reducing the probability of errors.

The actuator provides 6 sets of passive dry contact feedback signals, and each set of signals can be freely defined by users according to their needs. There are up to 11 defined options, which can meet the control requirements of the DCS system through different combinations. For situations that require more feedback signals, expansion circuits can be installed to increase the number of contacts, up to a maximum of 6 contacts.
Fault self-diagnosis, worry-free and effortless
Various faults may occur during the operation of the actuator, such as power phase loss, motor overheating, signal loss, internal faults, etc. The actuator can diagnose various faults on its own and protect it, while also sending alarm information to the central control room (DCS or PLC, etc.) and displaying the fault type on the actuator's display screen, thereby shortening the time to find faults.
Phase sequence self-discrimination, random wiring
The actuator can automatically identify the phase sequence of the three-phase power supply connected by the user, and always ensure that the actions of the actuator in the direction of opening and closing are correctly executed, without the need for the user to consider the phase sequence of the three-phase power supply.
Valve position detection, always correct
Using a magnetic absolute encoder to detect the position information of the actuator, even if the valve position is changed by manually turning the handwheel in the event of a power outage, the position information will not be incorrect and does not require battery support.
Current calibration and calibration, worry-free accuracy
The actuator can accurately calibrate the 4-20mA control current sent to the actuator from the central control room, thereby improving the control accuracy of the actuator; The executing agency can also accurately calibrate the 4-20mA position current sent to the central control room, thus meeting the detection accuracy requirements of the central control room for position current.
Signal inquiry, fast and convenient
The executing agency can query various control commands (signals) sent to the executing agency by the central control room to understand whether the executing agency has correctly received the instructions issued by the central control room.
