Failure Symptoms

Early indications of a failing bridge valve may include inconsistent hydraulic operation or slight pressure drops during load changes. If ignored, this can lead to more pronounced issues such as sluggish actuator response or uncontrolled hydraulic movements. Continued operation with a faulty bridge valve risks damage to other hydraulic components and potential operational interruptions.

Installation Tip

Thoroughly clean the mounting surface and ensure all sealing surfaces are free of debris or damage before installing the new valve. Avoid over-tightening the mounting bolts, as this can warp the valve body and cause leaks.

Service Note

Inspect the hydraulic fluid and filter for any signs of contamination or wear particles during the replacement of this bridge valve.
