Doosan DH420 DH500 Control Relief Valve LNC0261 Excavator Parts
As a safety valve, the overflow valve used to prevent hydraulic system overload is normally closed, as shown in Figure a. When the pressure in front of the valve does not exceed a preset limit, the valve closes without oil leakage. When the pressure in front of the valve exceeds this limit value, the valve immediately opens, and the oil flows back to the oil tank or low-pressure circuit, thus preventing overloading of the hydraulic system. Usually, safety valves are mostly used in systems with variable displacement pumps, and the overload pressure they control is generally 8% to 10% higher than the working pressure of the system.
Attention: If the cone valve or main valve core is excessively worn or the sealing surface is in poor contact, it will also cause excessive internal leakage and even affect normal operation

For safe drainage purposes.
When the pressure inside the pipeline reaches the set pressure of the overflow valve, the overflow valve automatically opens and discharges. When the pressure inside the pipeline decreases, the overflow valve automatically closes, stopping pressure relief, and providing safety protection for the pipeline.
