What to do if my Air Torque Controller loses power?
- P
  Patrick HuffmanAug 9, 2025
  If your Air Torque Controller experiences a loss of power, first ensure that the supply pressure is correct by checking the control system. Then, inspect all tubing and fittings for blockages, compression, or sealing issues, removing any obstructions or damaged parts. Also, you should disassemble the actuator to inspect and replace any damaged seals. Check the air exhaust hole and remove any plugs or foreign objects that may be blocking it.

Why is my Air Torque AT101U rotation uneven?
- J
  Jamie OrtegaAug 19, 2025
  Uneven rotation in your Air Torque Controller can stem from several causes. Start by checking the supply system to ensure the pressure is correct. If that's not the issue, the actuator may need lubrication; disassemble it, lubricate all sliding parts, and then reassemble. Worn or damaged components can also cause this, so inspect and replace any that are faulty. Ensure the control system components are correctly assembled. If the actuator is mounted on a valve, consult the valve documentation and contact the manufacturer for assistance.

  Incomplete rotation of your Air Torque Controller can occur due to several reasons. First, ensure the stroke is correctly adjusted. Next, disassemble the actuator and check for any foreign objects inside. Also, incorrect assembly after maintenance can cause this issue, so disassemble and reassemble the actuator correctly. Make sure the control system components are correctly assembled. If the actuator is mounted on a valve, check the valve documentation and contact the manufacturer.
