Failure Symptoms

Initial signs of a failing valve seat insert may include a slight decrease in hydraulic system responsiveness or a subtle increase in operating temperature. If ignored, the issue can progress to noticeable power loss, inconsistent actuator movement, and potential fluid leakage. Continued operation with a compromised valve seat can lead to accelerated wear on other hydraulic components.

Installation Tip

Ensure the valve body mating surface is perfectly clean and free of debris before attempting installation. Avoid using excessive force or improper tools, which can damage the new seat or the valve body.

Service Note

Inspect the associated valve spool and hydraulic fluid for contamination when replacing the valve seat insert.
