Case Construction Equipment N7655 Safety Relief Valve

Case Construction Equipment N7655 Safety Relief Valve is a hydraulic relief valve designed to protect Case wheel loader circuits from overpressure. It is specified to fit Case W18, W18B, W20, W20A, and W20B wheel loaders, aligning with the machines' hydraulic port layouts and control circuits. In operation, a relief valve of this type monitors system pressure and vents excess fluid back to the reservoir when preset thresholds are exceeded, helping prevent pump cavitation, hose bursts, and actuator damage during pressure spikes. As part of routine maintenance or component diagnosis, technicians reference the N7655 designation to identify the correct valve for the loader's hydraulic system, ensuring compatibility with the machine's service procedures. Because the models listed share common hydraulic architectures in the W-series lineup, the N7655 relief valve provides a targeted solution for overpressure protection on these specific Case wheel loaders. Verify model compatibility and part number before ordering to ensure a precise fit and proper hydraulic performance.
