What to do if Parker Control Unit valve does not switch on?
- JJessica MuellerAug 11, 2025
If the Parker Control Unit valve isn't switching on, begin by verifying the electrical connections. If the wiring is correct, check the general control system for a signal. A defective coil could also be the culprit; measure its resistance and replace if necessary. Additionally, examine the operating conditions and fastening bolt torques. If these are correct, the valve may need inspection by the manufacturer. Finally, for pilot operated valves, ensure there is adequate pilot oil pressure and delivery.
