      If you're experiencing a fault with the ROTADISK Pneumatic Actuator on your Flowserve Controller, begin by ensuring the control unit has a power supply. If not, connect it. Next, verify the compressed air supply is connected and that no vents are blocked. Following that, inspect the control air lines for leaks, obstructions, and proper routing. Finally, check that all control components are correctly connected and are switching in response to a control signal.

      If you're encountering a fault on the valve of your Flowserve Controller, first, check the add-on between the pneumatic actuator and the valve for defects or incorrect installation; repair or correctly install if necessary. Also, the pneumatic actuator could be too weak, so design the control pressure or sparing package correctly. Finally, a defective transmission shaft/ball connection could be the cause, so repair the valve.
