What to do if my Eaton Vickers DF3S4-16 Control Unit valve spool fails to move?
- EEmily LewisAug 10, 2025
If the valve spool on your Eaton Control Unit fails to move, there are several potential causes. First, check for dirt in the system, and if present, disassemble, clean, and flush the unit. Next, verify the solenoids are working by checking the electrical source and the solenoids themselves. Also, ensure the unit is assembled correctly by referring to the appropriate figure and assembly procedure. Finally, confirm that the installation connections are correct by checking the installation drawings.
