      Jordan CarrollAug 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.

      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.

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.
