FAQ

Home / Resources / FAQ

  • Q Who should I contact if problems arise?

    A Please contact us first. We work with qualified freight forwarders and shipping companies, and coordinate the whole process including customs clearance and insurance claims. In case of major disputes, we will assist in liaising with relevant authorities to fully protect your rights and interests.

  • Q Will the goods be detained due to the conflict?

    A The probability is extremely low. We avoid high-risk routes and ports, clearly state that the products are for non-military use, and verify document compliance in advance to avoid detention risks from the source. If any abnormality occurs, we can coordinate and resolve it quickly.

  • Q How do you guarantee delivery?

    A We prioritize air freight for urgent orders, or sea/multimodal transport via ports in Oman to bypass high-risk areas. We prepare all customs clearance documents in advance, including mandatory certifications such as Saudi SABER and EMC test reports, and take out war risk insurance. We track cargo status in real time to ensure delivery control. With mature processes, we have extensive experience in Middle East project deliveries.

  • Q Q: What are the key points of daily maintenance for the actuator?

    A
    A: Regularly check the sealing parts (such as O-rings) and the lubrication state of transmission parts, and clean the wiring terminals; calibrate the torque protection, limit switch and feedback accuracy quarterly, and record the operation data to facilitate fault prediction.

  • Q Q: How to purchase original spare parts? What are the precautions for replacement?

    A
    A: Purchase through official channels or authorized distributors and provide the product model and spare parts code; after replacing key components such as encoders and motors, the valve position and torque parameters must be recalibrated to ensure normal communication and feedback.

  • Q Q: How long is the product warranty period? How to handle man-made damage?

    A A: The warranty period for core components is usually 12-24 months (subject to the contract agreement); non-man-made faults are repaired free of charge, and parts and labor fees are charged for man-made damage or out-of-warranty maintenance. Paid extended warranty service is provided.

  • Q Q: How to obtain technical support in case of equipment failure?

    A A: Call the official after-sales hotline and provide the product model, fault phenomenon, alarm code and on-site working conditions; the engineers will guide the troubleshooting remotely. On-site service will be arranged if necessary, and the core components will be repaired and replaced free of charge within the warranty period.

  • Q Q: How to ensure the adaptation to the valve during installation?

    A A: Check the coincidence of the drive shaft sleeve groove and the hollow output shaft key, and fix the bearing retainer firmly; the connecting flange of the actuator and the valve must be cleaned, and the bolts should be tightened evenly to avoid eccentric load.

  • Q Q: What technical parameters need to be provided for product selection?

    A
    A: It is required to provide the rated torque of the valve, flange size, valve stem diameter/thread, control mode (on-off/analog/digital), feedback mode, power supply mode and medium working conditions, etc.

  • Q Cause Analysis and Troubleshooting Methods for "Phase Loss" Alarm in CKD Actuators

    A
    • Cause Analysis 1: Loss of one phase in the three-phase power supply of the actuator.
    Troubleshooting Method 1: Inspect the external power supply for normality and eliminate faults in the power distribution system and lines.
     
    • Cause Analysis 2: Damage to circuit components related to the power board.
    Troubleshooting Method 2: Replace with a power board of the same model.

  • Q Cause Analysis and Troubleshooting Methods for "Start-up Timeout" or "Motor Stall" Faults in CKD Actuators

    A
    • Cause Analysis 1: Manual/Electric Switching Device is jammed, leading to motor idling.
    Troubleshooting Method 1: Control the actuator to reverse; if it operates normally, the fault is resolved. If switching to electric mode fails after repeating the above operation multiple times, contact the manufacturer.
     
    • Cause Analysis 2: External obstacles affecting the normal operation of the actuator (e.g., valve jamming).
    Troubleshooting Method 2: User shall eliminate the external obstacles that hinder the actuator's normal operation.
     
    • Cause Analysis 3: Poor contact or damage to the Motor Control Unit (MCU).
    Troubleshooting Method 3: Inspect the cable connections of the MCU and check for signs of damage to the unit itself.
     
    • Cause Analysis 4: Disconnection between the Position Detection Unit and the Signal Feedback Shaft.
    Troubleshooting Method 4: Check if the encoder is disconnected from the Signal Feedback Shaft or if the contact is unreliable.
     
    • Cause Analysis 5: Failure of the Position Detection Unit.
    Troubleshooting Method 5: Replace the encoder.

  • Q Cause Analysis and Troubleshooting Methods for "No Display Upon Power-on" Fault in CKD Actuators

    A
    • Cause Analysis 1: Power failure of the three-phase power supply.
    Troubleshooting Method 1: Inspect the external power supply for normality and eliminate faults in the power distribution system and lines.
     
    • Cause Analysis 2: Blown fuse on the primary side of the transformer on the power board.
    Troubleshooting Method 2: Replace with a fuse of the same model.
     
    • Cause Analysis 3: Abnormal output voltage of the power board.
    Troubleshooting Method 3: Replace the power board.
     
    • Cause Analysis 4: Failure of the display board.
    Troubleshooting Method 4: Replace the display board.

  • Q Cause Analysis and Troubleshooting Methods for "Motor Overheating" Fault in CKD Actuators

    A
    • Cause Analysis 1: The motor operates continuously for a long time, with the temperature exceeding 130℃, causing the temperature switch to automatically disconnect.
    Troubleshooting Method 1: Suspend the actuator's operation and resume work only after the motor temperature cools down.
     
    • Cause Analysis 2: Damage to the temperature switch inside the motor.
    Troubleshooting Method 2: Temporarily short-circuit the temperature detection connector for short-term operation. Replace the motor during maintenance.
     
    • Cause Analysis 3: Damage to circuit components related to the main control board.
    Troubleshooting Method 3: Replace with a main control board of the same model.

  • Q Cause Analysis and Troubleshooting Methods for "Over-torque" Fault in CKD Actuators

    A
    • Cause Analysis 1: The torque protection setting value is too low.
    Troubleshooting Method 1: Increase the torque protection setting value.
     
    • Cause Analysis 2: External obstacles affecting the normal operation of the actuator (e.g., valve jamming).
    Troubleshooting Method 2: User shall eliminate the external factors that hinder the actuator's normal operation.
     
    • Cause Analysis 3: Mismatch between the actuator selection and on-site operating conditions.
    Troubleshooting Method 3: Select and replace with a model matching the on-site requirements.
     
    • Cause Analysis 4: Damage to relevant components on the main control board.
    Troubleshooting Method 4: Replace the main control board.
