Why Flowserve Valtek MaxFlo 4 Control Unit valve moves to failure position and has excessive air bleeding?
- SSarah FordAug 13, 2025
The valve moving to the failure position with excessive air bleeding could be due to a failure of the cylinder actuator O-ring, in which case you should replace the actuator O-ring. Alternatively, it could be due to a failure of the sliding seal assembly in the cylinder actuator, requiring you to repair or replace the sliding seal assembly.
