Frequently Asked Questions
How do I choose the right electric actuator model?
Consider the following factors: valve type (e.g. ball valve, butterfly valve), required torque/thrust, power supply (AC/DC), control signal (e.g. 4–20mA, on/off), protection rating (IP level), explosion-proof requirements (e.g. ATEX), and ambient temperature.
How is the actuator torque calculated?
Refer to the valve manufacturer's data for the required operating torque, then add a safety margin of 20–30%. In some applications, factors like medium pressure and sealing class should also be considered.
What should I pay attention to when wiring the electric actuator?
Ensure the power supply matches the actuator specifications. Signal cables should be shielded and grounded, and should not run parallel with power cables to avoid interference.
How do I set travel limits and torque protection?
AOX electric actuators use mechanical limit screws or electronic parameter settings. Please refer to the user manual for manual or automatic calibration instructions.
How do I switch to manual mode?
AOX actuators can be switched to manual mode using a handwheel or clutch handle. Manual operation is required when the power is off.
What is the recommended maintenance cycle?
It is recommended to inspect sealing performance, lubricate gears, and clean external dust every 6–12 months.
What should I do if the fault code shows “Overload”?
Check if the valve is stuck or if the torque setting is too low. After resolving the issue, reset the actuator and test again.
What communication protocols are supported for your electric actuators?
Common supported protocols include Modbus RTU, Profibus, and HART. Ensure compatibility with your control system.
What is your warranty period?
Typically 1 year, depending on the terms specified in the contract.
