Removal and Installation of the Feedback Mechanism of the Flowserve Logix 3800 Positioner



This video demonstrates the removal and installation of the feedback mechanism of the Flowserve Logix 3800 valve positioner.

Make sure the valve is bypassed or in a safe condition. Disconnect power to the positioner. Disconnect air supply to the positioner. Remove the take off arm and follower arm.

Note, it is recommended that when the positioner is removed from the valve, it is taken to a clean work environment for disassembly and reassembly.

Note, the procedure is the same for both intrinsically safe, or explosion-proof, positioners.

Begin by removing the three screws that attach the feedback assembly to the positioner housing. Install the replacement feedback assembly to the positioner housing.

Note, the orientation is irrelevant since the feedback mechanism has a clutch. Torque the screws to 0.9 Newton meters or 8 inch pounds. Next reconnect the positioner follow arm and take off arm to the valve.
