How to fix incorrect valve position on a Rotork Controller?
- S
  sbuckleyAug 3, 2025
  An incorrect valve position on your Rotork Controller could be due to a few reasons. Check the position of the mechanical stop bolts and readjust them if they are incorrectly set. Also, check the limit switch position if there's an incorrect signal from the limit switches. It may also be due to a fault of the pipeline valve, in which case you should consult the valve manufacturer’s documentation.

Why is my Rotork Controller losing power?
- P
  Pamela BrandtAug 8, 2025
  Loss of power in your Rotork Controller can occur due to several reasons. It might be caused by inadequate supply pressure. Ensure that the supply pressure exceeds the minimum operating pressure and provides enough torque for the valve. Incorrect speed control settings may also be the cause; adjust the speed controls to increase flow. Blocked, crushed, or leaking pipework can also lead to power loss, so examine the pipework and clear or replace any damaged sections. If control accessories are present and faulty, contact Rotork. High valve torque or incorrect sizing can also be a factor, so consult the valve manufacturer’s documentation.

What to do if my Rotork Controller has erratic movement?
- A
  Audrey RamirezAug 13, 2025
  Erratic movement in your Rotork Controller can be caused by a few things. First, verify the supply pressure and correct it if it's irregular. It may also be due to worn parts, in which case you should dismantle and visually inspect for significant wear; actuator replacement may be required. If control accessories are present, a fault in them could be the cause, so contact Rotork. Lastly, the issue may stem from a fault in the pipeline valve, in which case you should consult the valve manufacturer’s documentation.

Why is there insufficient valve rotation in my rotork K-TORK?
- A
  Alexa CarterAug 18, 2025
  Insufficient valve rotation in your Rotork Controller might occur due to: 1. Insufficient air supply. Increase air supply flow. 2. Incorrect setting of mechanical stops. Adjust the stop bolts. 3. Debris left in the actuator during maintenance. Disassemble the actuator to remove debris and then reassemble it. It may also be due to a fault of the pipeline valve, in which case you should consult the valve manufacturer’s documentation.
